CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application is a continuation of International Patent Application No. PCT/CN2016/088721 filed on Jul. 5, 2016, which is hereby incorporated by reference in its entirety. 
    
    
     TECHNICAL FIELD 
     The present disclosure relates to the intelligent transportation field, and in particular, to a vehicle management method and apparatus. 
     BACKGROUND 
     An intelligent transportation system (ITS) integrates and applies advanced technologies such as an information technology, a communications technology, a sensing technology, a control technology, and a computer technology in order to establish a real-time, accurate, efficient, and comprehensive transportation management system that plays an all-round role in a wide range. Automated driving plays an essential role in the ITS. By means of automated driving, a disadvantage of a human driver in determining, reaction, and operation can be effectively avoided in order to improve transportation safety. Automated driving can make better use of information and resources provided by a transportation system in order to improve transportation efficiency. 
     Currently, in the ITS, an automated driving technology frees people from a vehicle driver role such that a vehicle provides a more convenient service for people. However, in the automated driving technology, vehicles cannot be distinguished from each other to use different scheduling rules. Consequently, a vehicle resource in the ITS cannot be flexibly used in the automated driving technology. 
     SUMMARY 
     Embodiments of the present disclosure provide a vehicle management method and apparatus in order to dynamically adjust a vehicle resource. 
     According to a first aspect, a vehicle management method is provided, including obtaining mode identifier information of a vehicle, where the mode identifier information indicates whether the vehicle is in a sharing mode or an exclusive mode, the sharing mode indicates that different users are allowed to share the vehicle, and the exclusive mode indicates that only a single user is allowed to use the vehicle, and scheduling the vehicle according to the mode identifier information. 
     According to the vehicle management method in an embodiment of the present disclosure, a management center obtains the mode identifier information of the vehicle and schedules the vehicle according to the mode identifier information of the vehicle in order to dynamically adjust the vehicle resource. 
     In this embodiment of the present disclosure, the mode identifier information of the vehicle may be determined by the management center or be set by a user for the vehicle. 
     In this embodiment of the present disclosure, the different users in the sharing mode may be at least two different users, and the single user may be one single user. 
     In some possible implementations, obtaining mode identifier information of a vehicle includes receiving the mode identifier information from the vehicle. 
     In this embodiment of the present disclosure, the mode identifier information of the vehicle that is received by a management device may be provided or sent by the vehicle. 
     Optionally, before receiving the mode identifier information from the vehicle, the method further includes sending a query message to the vehicle, where the query message is used to obtain the mode identifier information. 
     In this embodiment of the present disclosure, the management device may actively query the mode identifier information from the vehicle. 
     In some possible implementations, the obtaining mode identifier information of a vehicle includes generating the mode identifier information according to vehicle usage information of an ITS. 
     Herein, the management device may receive the mode identifier information sent by the vehicle, and may also independently generate or set the mode identifier information with reference to the vehicle usage information. 
     In some possible implementations, after the obtaining mode identifier information of a vehicle, the method further includes sending the mode identifier information to the vehicle such that the vehicle uses the sharing mode or the exclusive mode. 
     After obtaining the mode identifier information of the vehicle, the management device may send the mode identifier information to the vehicle such that the vehicle uses the sharing mode or the exclusive mode according to the mode identifier information. 
     Optionally, the method further includes setting the mode identifier information for the vehicle. 
     Therefore, the management device may directly set the mode identifier information for the vehicle, or the management center sends specified mode identifier information to the vehicle such that the vehicle changes a status of the vehicle according to the mode identifier information. 
     With reference to the first aspect, in a first possible implementation, scheduling the vehicle according to the mode identifier information includes obtaining a driving route plan of a usage to-be-allowed user when the mode identifier information indicates that the vehicle is in the sharing mode, where the usage to-be-allowed user is another user other than a usage allowed user, and the usage allowed user is a user that has been allowed to use the vehicle, and sending a first vehicle usage notification message to the vehicle when a driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user, where the first vehicle usage notification message includes identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user in order to instruct the vehicle to execute a command that is input by the user and that is corresponding to the driving route plan of the user. 
     Therefore, when the vehicle is in the sharing mode, the management device may schedule the vehicle to both the usage to-be-allowed user and the usage allowed user, and send related information of the usage to-be-allowed user to the vehicle. 
     Optionally, before obtaining a driving route plan of a usage to-be-allowed user, the method further includes obtaining the driving route plan of the usage allowed user, and sending a second vehicle usage notification message to the vehicle, where the second vehicle usage notification message includes identity information of the usage allowed user and the driving route plan of the usage allowed user. 
     Therefore, when the vehicle is in the sharing mode, the management device may preobtain the driving route plan of the usage allowed user such that the vehicle learns of related information of the usage allowed user in order to properly arrange the usage to-be-allowed user and the usage allowed user to share the vehicle. 
     In some possible implementations, obtaining a driving route plan of a usage to-be-allowed user includes receiving a first vehicle usage request message of the usage to-be-allowed user, where the first vehicle usage request message includes the identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user. 
     Herein, the management device may obtain the driving route plan of the usage to-be-allowed user by receiving the first vehicle usage request message of the usage to-be-allowed user. 
     In some possible implementations, obtaining the driving route plan of the usage allowed user includes receiving a second vehicle usage request message of the usage allowed user, where the second vehicle usage request message includes the identity information of the usage allowed user and the driving route plan of the usage allowed user. 
     Similarly, the management device may obtain the driving route plan of the usage allowed user by receiving the second vehicle usage request message of the usage allowed user. 
     With reference to the first aspect, in a second possible implementation, scheduling the vehicle according to the mode identifier information includes obtaining a driving route plan of the single user when the mode identifier information indicates that the vehicle is in the exclusive mode, and sending a third vehicle usage notification message to the vehicle, where the third vehicle usage notification message includes identity information of the single user and the driving route plan of the single user. 
     Herein, when the mode identifier information of the vehicle indicates that the vehicle is in the exclusive mode, the management device may schedule the vehicle to only the single user for use, and send related information of the single user to the vehicle. 
     Therefore, when the vehicle is in the exclusive mode, the management device may schedule the vehicle to only the single user for use, and send the related information of the single user to the vehicle. 
     Optionally, in some possible implementations, the management center determines, according to the mode identifier information, a vehicle resource set corresponding to the vehicle, and schedules the vehicle according to the vehicle resource set corresponding to the vehicle. 
     Optionally, determining, according to the mode identifier information, a vehicle resource set corresponding to the vehicle includes determining that the vehicle resource set corresponding to the vehicle is a shared vehicle resource set when the mode identifier information indicates that the vehicle is in the sharing mode. 
     Optionally, determining, according to the mode identifier information, a vehicle resource set corresponding to the vehicle includes determining that the vehicle resource set corresponding to the vehicle is an exclusive vehicle resource set when the mode identifier information indicates that the vehicle is in the exclusive mode. 
     Optionally, the vehicle is scheduled according to the vehicle resource set corresponding to the vehicle. 
     Therefore, in a specific implementation process, the management device may classify vehicles into different vehicle resource sets according to mode identifier information of the vehicles in order to facilitate subsequent scheduling of a corresponding vehicle according to the vehicle resource sets. 
     According to a second aspect, a vehicle management method is provided, including receiving a vehicle scheduling message sent by a management device according to mode identifier information of a vehicle, where the mode identifier information indicates whether the vehicle is in a sharing mode or an exclusive mode, the sharing mode indicates that different users are allowed to share the vehicle, and the exclusive mode indicates that only a single user is allowed to use the vehicle, and performing usage control according to the vehicle scheduling message. 
     According to the vehicle management method in an embodiment of the present disclosure, the vehicle receives the vehicle scheduling message sent by the management device according to the mode identifier information, and performs the usage control according to the vehicle scheduling message such that the management device can dynamically adjust a vehicle resource. 
     For example, that the vehicle performs the usage control according to the vehicle scheduling message includes executing, according to a driving route plan of a user, a command that is input by the user and that is corresponding to the driving route plan of the user. 
     Herein, the driving route plan of the user may be an original driving route plan of the user, for example, a driving route plan of the usage to-be-allowed user in the exclusive mode of the vehicle or a driving route plan of the single user in the sharing mode of the vehicle, or may be a processed driving route plan of the usage to-be-allowed user, for example, a processed driving route plan of the usage to-be-allowed user in the sharing mode of the vehicle. 
     The processed driving route plan of the usage to-be-allowed user is a driving route plan obtained after the driving route plan of the usage to-be-allowed user and the driving route plan of the usage allowed user are combined or integrated. 
     With reference to the second aspect, in a first possible implementation, the method further includes obtaining the mode identifier information of the vehicle, and using the sharing mode or the exclusive mode according to the mode identifier information. 
     Optionally, in some possible implementations, the obtaining mode identifier information of a vehicle includes receiving the mode identifier information set by a user, where the user includes a vehicle owner, a user that has management permission of the vehicle, or a user that is allowed to change a status of the vehicle. 
     A permission level of the vehicle owner, a permission level of the user that has the management permission of the vehicle, and a permission level of the user that is allowed to change the status of the vehicle are in a descending order. That is, the vehicle owner has highest permission of the vehicle, the user that has the management permission of the vehicle is a specified permission owner set by the vehicle owner, and the user that is allowed to change the status of the vehicle includes a user that is allowed to change the status of the vehicle and that is set by the vehicle owner or the user that has the permission of the vehicle. 
     Therefore, in the present disclosure, the mode identifier information that is received may also be set by a user. Similarly, the mode identifier information set by the user may also be provided for the management device. 
     With reference to the second aspect or the first possible implementation of the second aspect, in a second possible implementation, the receiving a vehicle scheduling message sent by a management device according to mode identifier information of a vehicle includes receiving a first vehicle usage notification message sent by the management device when the mode identifier information of the vehicle indicates that the vehicle is in the sharing mode, where the first vehicle usage notification message includes identity information of a usage to-be-allowed user and a driving route plan of the usage to-be-allowed user, the usage to-be-allowed user is another user other than a usage allowed user, the usage allowed user is a user that has been allowed to use the vehicle, and a driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user. 
     Therefore, when the vehicle is in the sharing mode, the vehicle may further receive the first vehicle usage notification message. The first vehicle usage notification message includes the identity information of the usage to-be-allowed user and a usage time plan of the usage to-be-allowed user. In this case, the vehicle may be shared by the usage to-be-allowed user and the usage allowed user. 
     Optionally, in some possible implementations, before receiving a first vehicle usage notification message sent by the management device, the method further includes receiving a second vehicle usage notification message sent by the management device, where the second vehicle usage notification message includes identity information of the usage allowed user and the driving route plan of the usage allowed user. 
     After the vehicle confirms the identity information of the usage to-be-allowed user, the usage allowed user and the usage to-be-allowed user are allowed to share the vehicle. For example, a driving route is readjusted, or the usage to-be-allowed user is picked up when convenient. The driving route plan of the usage allowed user and the driving route plan of the usage to-be-allowed user are combined for driving. 
     With reference to the second aspect or the first possible implementation of the second aspect, in a third possible implementation, receiving a vehicle scheduling message sent by a management device according to mode identifier information of a vehicle includes receiving a third vehicle usage notification message sent by the management device when the mode identifier information of the vehicle indicates that the vehicle is in the exclusive mode, where the third vehicle usage notification message includes identity information of the single user and a driving route plan of the single user. 
     Therefore, when the vehicle is in the exclusive mode, the vehicle may receive the identity information of the single user and the driving route plan of the single user such that the vehicle is used by only the single user. 
     Optionally, in some possible implementations, when the vehicle is in the exclusive mode, the method further includes receiving a fourth vehicle usage notification message sent by the management device, where the fourth vehicle usage notification message includes identity information of a non-single user and a driving route plan of the non-single user, and the non-single user is another user other than the single user, and sending a rejection message to the management device, where the rejection message is used to indicate rejection of executing the fourth vehicle usage notification message. 
     Therefore, when the vehicle is in the exclusive mode, the vehicle receives the third vehicle usage notification message, where the third vehicle usage notification message includes the identity information of the single user and a usage time plan of the single user, and afterwards, if the vehicle further receives related vehicle usage information of another user other than the single user, the vehicle may send the rejection message to the management device to indicate rejection of executing the fourth vehicle usage notification message. 
     Optionally, when the vehicle is in the exclusive mode, the vehicle may also choose to receive the fourth vehicle usage notification message if the vehicle is idle, and send a response message to the management device. The response message is used to indicate that the vehicle agrees to receive the fourth vehicle usage notification message. 
     That is, when the vehicle is in the exclusive mode, if the vehicle is in an idle state, the vehicle may choose to receive the fourth vehicle usage notification message. 
     Optionally, the vehicle and the management device may determine or change the mode identifier information of the vehicle using a negotiation mechanism. 
     Optionally, in some possible implementations, after the mode identifier information is provided for the management device, the method further includes receiving new mode identifier information from the management device, and updating the current mode identifier information using the new state identifier message. 
     The vehicle receives the mode identifier information set by the management device. The mode identifier information is mode identifier information that is for updating the vehicle and that is set or generated by the management device according to vehicle usage information of an ITS. 
     Optionally, in some possible implementations, the method further includes sending the mode identifier information to the management device. 
     Herein, the vehicle sends the mode identifier information to the management device such that the management device generates the vehicle scheduling message according to the mode identifier information. 
     Optionally, in some possible implementations, before the mode identifier information of the vehicle is provided for the management device, the method further includes receiving a query message sent by the management device, where the query message is used by the management device to obtain the mode identifier information. 
     According to a third aspect, a vehicle management apparatus is provided, where the vehicle management apparatus is configured to perform the method in the first aspect or any possible implementation of the first aspect. The apparatus includes a unit that is configured to perform the method in the first aspect or any possible implementation of the first aspect. 
     According to a fourth aspect, a vehicle is provided, where the vehicle is configured to perform the method in the second aspect or any possible implementation of the second aspect. The apparatus includes a unit that is configured to perform the method in the second aspect or any possible implementation of the second aspect. 
     According to a fifth aspect, a vehicle management apparatus is provided. The apparatus includes a processor, a memory, and a communications interface. The processor is connected to the memory and the communications interface. The memory is configured to store an instruction. The processor is configured to execute the instruction. The communications interface is configured to communicate with another network element under the control of the processor.

     DESCRIPTION OF EMBODIMENTS 
     The following clearly describes the technical solutions in the embodiments of the present disclosure with reference to the accompanying drawings in the embodiments of the present disclosure. 
     The technical solutions of the present disclosure may be applied to scenarios such as an ITS or an ITS based on an Internet of Things (IoT) technology. According to the ITS, an advanced information technology, a data communication technology, a sensor technology, an electronic control technology, a computer technology, and the like are effectively integrated to be used in an entire transportation management system in order to establish a comprehensive transportation and management system that plays an all-round role in a wide range, for example, an urban transportation intelligent scheduling system, a motor vehicle auto control system, a station passenger flow grooming system, and a highway intelligent scheduling system.  FIG. 1  shows a schematic diagram of an application scenario of an ITS according to an embodiment of the present disclosure. It should be noted that the example in  FIG. 1  is intended to help a person skilled in the art better understand this embodiment of the present disclosure, instead of limiting the scope of this embodiment of the present disclosure. 
     As shown in  FIG. 1 , the ITS may include a transportation management subsystem  11 , a vehicle control subsystem  12 , and a transportation information subsystem  13 , and the like. Main transportation participants in the system include a user  14 , a management center  15 , a vehicle  16 , an infrastructure  17 , and the like. The transportation management subsystem  11  is responsible for coordinating and controlling actions of the transportation participants (including  14 ,  15 ,  16 , and  17 ) according to transportation information. The vehicle control subsystem  12  is responsible for safely and efficiently controlling driving of the vehicle  16 . The transportation information subsystem  13  is responsible for correctly collect, process, and exchange information about the transportation participants (including  14 ,  15 ,  16 , and  17 ) in time. Both the user  14  and the vehicle  16  are general terms. The user  14  may include multiple users, and the vehicle  16  may include multiple vehicles. 
     The user in this embodiment of the present disclosure may be a vehicle owner, a permission owner specified by the vehicle owner, or a user allowed by the vehicle owner to use the vehicle. Generally, identity authentication information of the vehicle owner is set when the vehicle is sold or delivered. The vehicle owner has highest permission, and the vehicle owner may set more users that are allowed by the vehicle owner to use the vehicle. The vehicle also saves identity authentication information of the users allowed by the vehicle owner, and sends, to the management center, the saved identity authentication information of the vehicle owner or the user allowed by the vehicle owner to use the vehicle 
     It should be understood that the identity authentication information of the user may include a user password (for example, a password identified based on input via a button, a touch sense, or a gesture), an identifier card (for example, an identity card, a phone card, or a key card), a biometric feature (for example, a fingerprint, a face, an iris), and the like. This is not limited herein. 
     In this embodiment of the present disclosure, the user and the vehicle interact in a relatively flexible manner. For example, the user may input identity authentication information using a man-machine interaction interface in order to interact with the vehicle. 
       FIG. 2  shows a schematic flowchart of a vehicle management method  200  according to an embodiment of the present disclosure. The method  200  is performed by the management center  15  in  FIG. 1 . For example, the management center may be a management device or a control center. The following uses the management center as an example for description. The method  200  includes the following steps. 
     Step S 210 . Obtain mode identifier information of a vehicle, where the mode identifier information indicates whether the vehicle is in a sharing mode or an exclusive mode, the sharing mode indicates that different users are allowed to share the vehicle, and the exclusive mode indicates that only a single user is allowed to use the vehicle. 
     Step S 220 . Schedule the vehicle according to the mode identifier information. 
     In this embodiment of the present disclosure, the management center obtains the mode identifier information of the vehicle. The mode identifier information is used to indicate whether the vehicle is in the sharing mode or the exclusive mode. The management center schedules the vehicle according to the mode identifier information to provide a transportation service in order to dynamically adjust a vehicle resource. 
     In this embodiment of the present disclosure, the different users may be at least two different users, and the single user may be one single user. 
     In this embodiment of the present disclosure, the mode identifier information may be received by the management center from the vehicle, or may be determined by the management center according to vehicle usage information of an ITS or a transportation service requirement. The management center may schedule or manage a vehicle in the ITS according to the mode identifier information obtained in any manner. 
     The mode identifier information may be a state identifier set by the user or the management center for the vehicle. The mode identifier information is used to identify whether the vehicle is in the sharing mode or the exclusive mode, or used to indicate whether the vehicle can be shared. The mode identifier information may be implemented using a flag bit. A data type of the mode identifier information may be an enumeration type, and a value includes sharing or exclusive. Alternatively, a data type of the mode identifier information may be an integer type, and a value includes 0 and 1, where the values 0 and 1 may be respectively corresponding to the exclusive mode and the sharing mode. Optionally, the mode identifier information further includes an effective duration of a state, for example, an effective duration of the exclusive mode or an effective duration of the sharing mode. 
     It should be understood that a value of the identifier bit of the mode identifier information corresponding to the sharing mode or the exclusive mode may be set according to a requirement, and the sharing mode or the exclusive mode does not necessarily to be corresponding to a specific value. 
     It should be noted that in this embodiment of the present disclosure, the mode identifier information (including a state identifier value corresponding to the mode identifier information and a meaning of a value of the mode identifier information) is uniformly defined in the ITS and is understood by all participants in the ITS. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the management center schedules the vehicle according to the mode identifier information of the vehicle in order to dynamically adjust the vehicle resource. 
     Optionally, after obtaining mode identifier information of a vehicle, the method further includes sending the mode identifier information to the vehicle such that the vehicle uses the sharing mode or the exclusive mode. 
     The management center sends the mode identifier information to the vehicle. Therefore, the vehicle uses the corresponding sharing mode or the exclusive mode according to the mode identifier information, or the management center enables the vehicle to be in the sharing mode or the exclusive mode. 
     Optionally, in an embodiment, scheduling the vehicle according to the mode identifier information includes when the mode identifier information indicates that the vehicle is in the sharing mode, obtaining a driving route plan of a usage to-be-allowed user, where the usage to-be-allowed user is another user other than a usage allowed user, the usage allowed user is a user that has been allowed to use the vehicle, and the sharing mode indicates that at least two people are allowed to use the vehicle, and sending a first vehicle usage notification message to the vehicle when a driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user, where the first vehicle usage notification message includes identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user. 
     If the mode identifier information indicates that the vehicle is in the sharing mode, the management center determines that the vehicle may be scheduled to both the usage allowed user and the usage to-be-allowed user for use. The usage allowed user is a user of the vehicle, and the usage to-be-allowed user is another user other than the usage allowed user. The management center obtains the driving route plan of the usage to-be-allowed user. When the management center determines that the driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user, the management center determines to schedule the vehicle to both the usage allowed user and the usage to-be-allowed user for use, and sends the first vehicle usage notification message to the vehicle. The first vehicle usage notification message includes the identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user. That is, when the vehicle is in the sharing mode, multiple users may be allowed to share the vehicle. Driving route plans of these users are the same or similar. The usage to-be-allowed user and the usage allowed user are different users in the foregoing-mentioned “different users” in the sharing mode. 
     In this embodiment of the present disclosure, that the driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user means that the driving route plans are the same or similar. For example, a driving route of the usage allowed user overlaps with a driving route of the usage to-be-allowed user, or a route can be modified in an acceptable degree for a pick-up. 
     In addition, if the driving route plan of the usage to-be-allowed user does not match the driving route plan of the vehicle, the management center may perform selection from other vehicles in the sharing mode in order to schedule a proper vehicle for the usage to-be-allowed user. 
     Optionally, before obtaining a driving route plan of a usage to-be-allowed user, the method further includes obtaining the driving route plan of the usage allowed user, and sending a second vehicle usage notification message to the vehicle, where the second vehicle usage notification message includes identity information of the usage allowed user and the driving route plan of the usage allowed user. 
     Certainly, before obtaining the driving route plan of the usage to-be-allowed user, the management center may preobtain the driving route plan of the usage allowed user, and schedule, according to the driving route plan of the usage allowed user, the vehicle to the usage allowed user for use. After obtaining the driving route plan of the usage to-be-allowed user, the management center may integrate the driving route plan of the usage allowed user and the driving route plan of the usage to-be-allowed user, and schedule, according to an integrated driving route plan, the vehicle to both the usage allowed user and the usage to-be-allowed user for use. Herein, before the vehicle is scheduled to both the usage allowed user and the usage to-be-allowed user for use or before the driving route plan of the usage to-be-allowed user is obtained, even though the mode identifier information of the vehicle indicates that the vehicle is in the sharing mode, the vehicle may be temporarily used by only the usage allowed user. This is not limited herein. 
     Optionally, obtaining a driving route plan of a usage to-be-allowed user includes receiving a first vehicle usage request message of the usage to-be-allowed user, where the first vehicle usage request message includes the identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user. 
     The management center may receive the first vehicle usage request message of the usage to-be-allowed user. The first vehicle usage request message includes the identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user. When determining to schedule the vehicle to both the usage allowed user and the usage to-be-allowed user for use, the management center sends the first vehicle usage notification message to the vehicle. The first vehicle usage notification message includes the identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user. Therefore, the vehicle authenticates the identity information of the usage to-be-allowed user according to the first vehicle usage notification message, and performs related processing according to the driving route plan of the usage to-be-allowed user. That is, when determining to schedule the vehicle to a user with a matched driving route plan, the management center may send a notification message to the vehicle. The notification message is used to instruct the vehicle to make related preparation. The notification message may include identity information and a get-on/off plan of an allowed sharing-required user. For example, the sharing-required user is the usage to-be-allowed user. The identity information may be identity authentication information or permission information of the usage to-be-allowed user, and the get-on/off plan is a get-on/off time or specific location information of the usage to-be-allowed user. 
     Optionally, obtaining the driving route plan of the usage allowed user includes receiving a second vehicle usage request message of the usage allowed user, where the second vehicle usage request message includes the identity information of the usage allowed user and the driving route plan of the usage allowed user. 
     The management center may receive the second vehicle usage request message of the usage allowed user. The first vehicle usage request message includes the identity information of the usage allowed user and the driving route plan of the usage allowed user. The management center determines, according to the driving route plan of the usage allowed user to schedule the vehicle to the usage allowed user, and sends the second vehicle usage notification message to the vehicle. The second vehicle usage notification message includes the identity information of the usage allowed user and the driving route plan of the usage allowed user such that the vehicle authenticates the identity information of the usage allowed user according to the second vehicle usage notification message, and travels according to the driving route plan of the usage allowed user. 
     It should be understood that a time and a channel for receiving or sending the identity information and a time and a channel for receiving or sending the driving route plan of the user are not limited in this embodiment of the present disclosure. The identity information and the driving route plan may be received or sent at a same time or at different times, and may also be carried in another proper message. This is not limited herein. 
     Optionally, in an actual data implementation process, for example, that the management center may determine, according to the mode identifier information, a vehicle resource set corresponding to the vehicle includes determining that the vehicle resource set corresponding to the vehicle is a shared vehicle resource set when the mode identifier information indicates that the vehicle is in the sharing mode. 
     Optionally, the management center schedules the vehicle according to the vehicle resource set corresponding to the vehicle. 
     The management center adds the vehicle into the shared vehicle resource set when the mode identifier information indicates that the vehicle is in the sharing mode. In a duration in which the vehicle can be shared, the management center receives a request message from the usage to-be-allowed user, where the usage to-be-allowed user is another user other than a current user of the vehicle, then matches the driving route plan of the usage to-be-allowed user with a driving route plan of each vehicle in the shared vehicle resource set, and determines to schedule the vehicle to both the usage allowed user and the usage to-be-allowed user for use when the driving route plan of the usage to-be-allowed user matches the driving route plane of the usage allowed user. 
     In this embodiment of the present disclosure, that the driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user means that the driving route plans are the same or similar. For example, a driving route of the usage allowed user overlaps with a driving route of the usage to-be-allowed user, or a route can be modified in an acceptable degree for a pick-up. 
     For example, when current mode identifier information of the vehicle is set to the sharing mode by a current user A, the management center adds the vehicle to the shared vehicle resource set after receiving the mode identifier information of the vehicle. In this case, if a user B sends, to the management center, a vehicle usage application request attached with identity information and a driving route of B, after the management center receives the request of B, the management center finds, from the shared vehicle resource set, A whose driving route plan is similar to or the same as the driving route of B, and the management center determines to combine the driving route of B with the driving route of A, that is, the management center adjusts the route or use a route the same as an original route such that A and B can share the vehicle. 
     It should be understood that in this embodiment of the present disclosure, a quantity of vehicles in the ITS or a quantity of users in the ITS is not limited, the usage allowed user and the usage to-be-allowed user are only used as an example herein for description, and processing should be flexibly performed according to a situation in practice. 
     It should be further understood that in this embodiment of the present disclosure, serial numbers “first”, “second”, and the like are merely used for distinguishing between different objects such as different users, and are not intended to limit the scope of this embodiment of the present disclosure. The present disclosure is not limited thereto. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the management center schedules the vehicle according to the mode identifier information of the vehicle in order to dynamically adjust the vehicle resource. 
     Optionally, in an embodiment, scheduling the vehicle according to the mode identifier information includes obtaining a driving route plan of the single user when the mode identifier information indicates that the vehicle is in the exclusive mode, and sending a third vehicle usage notification message to the vehicle, where the third vehicle usage notification message includes identity information of the single user and the driving route plan of the single user. 
     If the mode identifier information indicates that the vehicle is in the exclusive mode, the management center determines that the vehicle may be scheduled to the single user, where the exclusive mode indicates that only the single user is allowed to use the vehicle. The management center obtains the driving route plan of the single user, determines to schedule the vehicle to the single user for use, and sends the third vehicle usage notification message to the vehicle. The third vehicle usage notification message includes the identity information of the single user and the driving route plan of the single user. Therefore, after confirming the identity information of the single user, the vehicle can travel according to the driving route plan of the single user. 
     Optionally, obtaining the driving route plan of the single user includes receiving a vehicle usage request message of the single user, where the vehicle usage request message includes the identity information of the single user and the driving route plan of the single user. 
     Optionally, in an actual data implementation process, for example, that the management center may determine, according to the mode identifier information, a vehicle resource set corresponding to the vehicle includes determining that the vehicle resource set corresponding to the vehicle is an exclusive vehicle resource set when the mode identifier information indicates that the vehicle is in the exclusive mode. 
     Optionally, that the management center schedules the vehicle according to the vehicle resource set corresponding to the vehicle includes scheduling the vehicle according to the driving route plan of the single user of the vehicle. 
     When the mode identifier information is exclusive mode identifier information, the management center adds the vehicle to the exclusive vehicle resource set, and then schedules the vehicle according to the driving route plan of the single user of the vehicle. After the management center receives the exclusive mode identifier information of the vehicle, in an effective duration of the exclusive mode of the vehicle, the management center performs scheduling according to only the driving route plan of the single user of the vehicle. For example, the usage allowed user is the current user of the vehicle. That is, in the ITS, the management center schedules the vehicle of the driving route plan of the single user in a whole-process coordination planning manner. Certainly, the management center may send a notification message to the vehicle. The notification message carries the driving route plan and the identity information of the single user. In an actual ITS environment, a vehicle owner or a vehicle property owner may not use his/her own vehicle because the vehicle may have been scheduled to another user for use. Therefore, to use the vehicle, the vehicle owner or the vehicle property owner needs to further make an application to the management center to authenticate an identity. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the management center schedules the vehicle according to the mode identifier information of the vehicle in order to dynamically adjust the vehicle resource. 
     Optionally, in an embodiment, step S 210  includes receiving the mode identifier information from the vehicle. 
     The management center may receive the mode identifier information provided or sent by the vehicle, and then use the mode identifier information as a reference for managing a related activity and matter. Herein, the mode identifier information sent by the vehicle is mode identifier information set by the user for the vehicle. That is, the management center may schedule the vehicle according to the mode identifier information sent by the vehicle to provide a transportation service. 
     Optionally, before receiving the mode identifier information from the vehicle, the method may further include sending a query message to the vehicle, where the query message is used to obtain the mode identifier information. 
     That is, the management center may send a query request to the vehicle, and actively query the mode identifier information of the vehicle. 
     Optionally, in an embodiment, step S 210  further includes generating the mode identifier information according to vehicle usage information of an ITS. 
     Optionally, the management center sets the mode identifier information for the vehicle. 
     In this embodiment of the present disclosure, mode identifier information set by the management center and mode identifier information set by the user have an equal effect. The management center sends the mode identifier information to the vehicle, or directly sets the mode identifier information for the vehicle. The management center schedules the vehicle according to the mode identifier information of the vehicle to dynamically adjust the vehicle resource. 
     In this embodiment of the present disclosure, a function of the vehicle usage information may be understood as that when a vehicle needs to be scheduled in an area in the ITS, the management device may determine, with reference to vehicle usage information of all vehicles managed by the management device in the ITS, whether to schedule a vehicle to provide a service in the area, or whether to schedule a vehicle out of the area. For example, the vehicle usage information may be an element such as a distance between a vehicle and a dense crowd area. 
     For example, the management center may adjust mode identifier information of a vehicle in the ITS in real time according to a scheduling requirement in the ITS, and send the mode identifier information to the vehicle, or the management center directly sets the mode identifier information for the vehicle. For example, because an area (a dense crowd area, an arterial road, and the like) in the ITS is prone to traffic congestion to improve utilization of a vehicle and release a vehicle flow burden, when a vehicle is driven into the area, the management center compels the vehicle to enable a sharing mode, that is, the management center compellingly sets mode identifier information of the vehicle to the sharing mode, where the mode identifier information is attached with a sharing mode identifier parameter and an effective duration. When the management center compels the vehicle to enable the sharing mode, another user in the area may share a shared vehicle in the area by means of scheduling by the management center. In this case, a user in the area may not need to own a vehicle, and use a shared vehicle in the area to implement shuttling (transferring or getting on a vehicle) in the area. For example, the user in the area may temporarily park his/her own vehicle outside the area. In an actual operation, the management center may provide a proper return for the vehicle that is compellingly switched to the sharing mode. 
     When changing the mode identifier information of the vehicle, the management center may simultaneously save an effective duration and a status of the vehicle before the vehicle is compelled to enable the sharing mode in order to recover the vehicle to an original exclusive or sharing mode after the duration of the compelled sharing mode ends. For example, when the vehicle leaves the foregoing area, the management center instructs the vehicle to end the compelled sharing mode, and attaches a state identifier parameter of the vehicle before the compelled sharing mode. 
     Certainly, instead of compellingly sharing, the management center may maintain, according to a requirement, an original status of some specific or professional vehicles (such as a police car and an ambulance) driven into the area. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the management center sets the mode identifier information for the vehicle, and schedules the vehicle according to the mode identifier information of the vehicle in order to dynamically adjust the vehicle resource. 
     The foregoing describes the vehicle management method according to this embodiment of the present disclosure from the perspective of the management center, and the following describes a vehicle management method according to an embodiment of the present disclosure from a vehicle side with reference to  FIG. 3 . 
       FIG. 3  shows a schematic flowchart of a vehicle management method  300  according to an embodiment of the present disclosure. The method is performed by a vehicle. The method  300  may be performed by a vehicle-mounted device of the vehicle or a proper device that is of the vehicle and that can communicate with a management center of an ITS. This is not limited herein. The method  300  includes the following steps. 
     Step S 310 . Receive a vehicle scheduling message sent by a management device according to mode identifier information of a vehicle, where the mode identifier information indicates whether the vehicle is in a sharing mode or an exclusive mode, the sharing mode indicates that different users are allowed to share the vehicle, and the exclusive mode indicates that only a single user is allowed to use the vehicle. 
     Step S 320 . Perform usage control according to the vehicle scheduling message. 
     In this embodiment of the present disclosure, the vehicle receives the vehicle scheduling message sent by the management device according to the mode identifier information, and performs the usage control according to the vehicle scheduling message such that the management device can dynamically adjust a vehicle resource. 
     For example, that the vehicle performs the usage control according to the vehicle scheduling message includes executing, according to a driving route plan of a user, a command that is input by the user and that is corresponding to the driving route plan of the user. 
     The command corresponding to the driving route plan of the user may include a command that is of a driving route plan and that is input by the user in the exclusive mode, or a command that is of a driving route plan and that is input by the user in the sharing mode. The driving route plan in the sharing mode may also be a driving route plan of the user before processing is performed, or a processed driving route plan of the user. The “processing” is combing or integrating multiple driving route plans. That is, the driving route plan in the exclusive mode does not need to be processed, and the command that is of the driving route plan and that is input by the user may be directly executed. However, the driving route plan in the sharing mode may be obtained after some processing is performed on driving route plans of multiple users, and finally, a command of a processed driving route plan is performed. 
     That is, the driving route plan of the user may be an original driving route plan of the user, for example, a driving route plan of the single user in the exclusive mode of the vehicle or a driving route plan of the usage to-be-allowed user in the sharing mode of the vehicle, or may be a processed driving route plan of the usage to-be-allowed user, for example, a processed driving route plan the user in the sharing mode of the vehicle. The processed driving route plan of the user is a driving route plan obtained after the driving route plan of the usage to-be-allowed user and the driving route plan of the usage allowed user are combined or integrated. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the vehicle receives the vehicle scheduling message sent by the management device according to the mode identifier information, and performs the usage control according to the vehicle scheduling message such that the management device can dynamically adjust the vehicle resource. 
     Optionally, the method further includes obtaining the mode identifier information of the vehicle, and using the sharing mode or the exclusive mode according to the mode identifier information. 
     In this embodiment of the present disclosure, the single user may be one single user. 
     The vehicle obtains the mode identifier information of the vehicle, and uses the sharing mode or the exclusive mode according to the mode identifier information. The sharing mode indicates that at least two different users are allowed to share the vehicle, and the exclusive mode identifier information is used to indicate that only a single user is allowed to use the vehicle. The vehicle may provide the mode identifier information for the management device such that the management device generates a vehicle usage notification message according to the mode identifier information. Therefore, the vehicle can implement a corresponding execution action according to different mode identifier information. 
     Optionally, obtaining the mode identifier information of the vehicle includes receiving the mode identifier information set by a user, where the user includes a vehicle owner, a user that has management permission of the vehicle, or a user that is allowed to change a status of the vehicle. 
     The vehicle may receive the mode identifier information set by the user, and sends the mode identifier information to the management center such that the management center determines, according to the mode identifier information, a vehicle resource set corresponding to the vehicle. 
     Herein, the user represents a common name of users that can set a vehicle status, and has no other presumable ambiguity. Certainly, the user is not limited to a vehicle owner. The user may include the vehicle owner, the user that has permission of the vehicle, or the user that is allowed to change the status of the vehicle. For example, the user may include, the vehicle owner (that has highest permission of the vehicle and can be set when the vehicle is delivered), a permission owner specified by the vehicle owner (the vehicle owner may set multiple users that has the permission of the vehicle, and the permission of the multiple users is lower than only the permission of the vehicle owner), and another user (that has lowest permission and that is allowed to change only the vehicle status) that is set by the vehicle owner or the permission owner specified by the vehicle owner and that is allowed to change the vehicle status. The vehicle owner or the permission owner specified by the vehicle owner has permission to set whether to allow another user of the vehicle to change the mode identifier information of the vehicle in a usage duration. That is, each of the vehicle owner, the permission owner specified by the vehicle owner, and the other user that is set by the vehicle owner or the permission owner specified by the vehicle owner and that is allowed to change the vehicle status may set the mode identifier information of the vehicle. 
     For example, when a management user plans to drive the vehicle to perform some activities or matters and drives through a road in a period, if the management user has no intention of sharing the vehicle with another user in the ITS (similar to a pick-up when convenient), the management user may set the mode identifier information of the vehicle to the exclusive mode and set an effective duration of the state. After receiving the mode identifier information set by the management user, the vehicle sends the mode identifier information to a management device (a control center, a scheduling center, or a management center) in the ITS. The parameter value of the mode identifier information indicates that the mode identifier information includes the corresponding effective duration and the vehicle is currently in the exclusive mode. After receiving the mode identifier information, the management center adds the vehicle to an exclusive vehicle resource set for management. During this period, the vehicle is scheduled according to only a driving route plan of the management user. 
     For another example, when a management user plans to drive the vehicle to perform some activities or matters and drives through a road in a period, if the management user has an intention of sharing the vehicle with another user in the ITS (similar to a pick-up when convenient), the management user may set the mode identifier information of the vehicle to the sharing mode and set an effective duration of the state. After receiving the mode identifier information set by the management user, the vehicle sends the mode identifier information to a management center (a control center, a scheduling center, or a management center) in the ITS. The mode identifier information includes the corresponding effective duration and a parameter value that indicates that the vehicle is currently in the sharing mode. After receiving a report message, the management center adds the vehicle into a shared vehicle resource set for management. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the vehicle receives the vehicle scheduling message sent by the management device according to the mode identifier information, and performs the usage control according to the vehicle scheduling message such that the management device can dynamically adjust the vehicle resource. 
     Optionally, obtaining the mode identifier information of the vehicle includes receiving new mode identifier information from the management device, and updating the mode identifier information according to the new state identifier message. 
     That is, the mode identifier information of the vehicle may be mode identifier information generated or set by the management center according to a transportation service scheduling requirement or vehicle usage information of the ITS. A method for determining the mode identifier information by the management center according to a scheduling requirement of the ITS is described above, and details are not described herein again. After receiving the mode identifier information set by the management center, the vehicle updates the mode identifier information of the vehicle according to the mode identifier information. For example, when the management center needs the vehicle to be set to the sharing mode, the vehicle changes the original exclusive mode to the sharing mode. In addition, after an effective duration of a changed state ends, the vehicle may receive a notification message from the management center, and be recovered to an original state. 
     Optionally, the method further includes sending the mode identifier information to the management device. 
     Optionally, before the mode identifier information of the vehicle is provided for the management device, the method further includes receiving a query message sent by the management device, where the query message is used by the management device to obtain the mode identifier information. 
     Optionally, receiving a vehicle scheduling message sent by a management device according to mode identifier information of a vehicle includes receiving a first vehicle usage notification message sent by the management device when the mode identifier information of the vehicle indicates that the vehicle is in the sharing mode, where the first vehicle usage notification message includes identity information of a usage to-be-allowed user and a driving route plan of the usage to-be-allowed user, the usage to-be-allowed user is another user other than a usage allowed user, the usage allowed user is a user that has been allowed to use the vehicle, and a driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user. 
     Optionally, before receiving a first vehicle usage notification message sent by the management device, the method further includes receiving a second vehicle usage notification message sent by the management device, where the second vehicle usage notification message includes identity information of the usage allowed user and the driving route plan of the usage allowed user. 
     When the mode identifier information of the vehicle indicates that the vehicle is in the sharing mode, the vehicle may further receive the second vehicle usage notification message before receiving the first vehicle usage notification message. The second vehicle usage notification message includes the identity information of the usage allowed user and the driving route plan of the usage allowed user. The driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user. That is, when the vehicle is in the sharing mode, the vehicle may receive the first vehicle usage notification message, and may further receive the second vehicle usage notification message sent by the management device. The second vehicle usage notification message includes the identity information of the usage allowed user and the driving route plan of the usage allowed user. In the sharing mode, before confirming the identity information of the usage to-be-allowed user, the vehicle also needs to authenticate the identity information of the usage allowed user. After completing the authentication, the vehicle allows the usage allowed user and the usage to-be-allowed user to share the vehicle. That is, the usage allowed user also needs to provide identity authentication information and a get-on/off plan of the usage allowed user. Then, according to a get-on/off plan of the usage to-be-allowed user, the vehicle adjusts and updates the original driving route plan of the usage allowed user, or keeps the original driving route plan of the usage allowed user unchanged such that the usage to-be-allowed user and the usage allowed user can share the vehicle to participate in an activity or a matter. 
     For example, when the vehicle is in the sharing mode, if another user sends a vehicle usage requirement message to the management center, the management center matches a driving route plan of the other user with a driving route plan of a current user of each vehicle in the shared vehicle resource set. If a vehicle whose driving route plan is the same as or similar to the driving route plan of the other user (for example, routes completely overlap, or a route can be modified in an acceptable degree) is found in the shared vehicle resource set, the management center determines to schedule the vehicle to the other user for use, and sends a notification message to the vehicle. The notification message includes identity authentication information and a get-on/off plan of the user. After receiving the notification message, the vehicle first confirms identity information of the user. Only after usage permission is confirmed, the other user can share the vehicle with the current user to complete a driving route. Certainly, the other user herein may be multiple users. The vehicle may be shared provided that routes or driving route plans of the multiple users are similar or same, and driving matters of the multiple users can be implemented after a vehicle route is adjusted within an acceptable range. 
     Optionally, the receiving a vehicle scheduling message sent by a management device according to mode identifier information of a vehicle includes receiving a third vehicle usage notification message sent by the management device when the mode identifier information of the vehicle indicates that the vehicle is in the exclusive mode, where the third vehicle usage notification message includes identity information of the single user and a driving route plan of the single user. 
     When the vehicle is in the exclusive mode, the vehicle may receive the third vehicle usage notification message. The third vehicle usage notification message includes the identity information of the single user and the driving route plan of the single user such that the vehicle is provided for only the single user to use. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the vehicle receives the vehicle scheduling message sent by the management device according to the mode identifier information, and performs the usage control according to the vehicle scheduling message such that the management device can dynamically adjust the vehicle resource. 
     Optionally, when the vehicle is in the exclusive mode, the method further includes receiving a fourth vehicle usage notification message sent by the management device, where the fourth vehicle usage notification message includes identity information of a non-single user and a driving route plan of the non-single user, and the non-single user is another user other than the single user, and sending a rejection message to the management device, where the rejection message is used to indicate rejection of executing the fourth vehicle usage notification message. 
     When the mode identifier information of the vehicle indicates that the vehicle is in the exclusive mode, the exclusive mode indicates that only the single user is allowed to use the vehicle, and the mode identifier information is obtained by the vehicle. The vehicle receives the fourth vehicle usage notification message sent by the management device. The fourth vehicle usage notification message includes the identity information of the non-single user and a usage time plan of the non-single user. The non-single user is another user other than the single user. In this case, after the vehicle receives the third vehicle usage notification message, the single user has used the vehicle in the exclusive mode. Therefore, the vehicle sends the rejection message to the management device. The rejection message is used to indicate rejection of executing the fourth vehicle usage notification message. 
     Optionally, when the mode identifier information of the vehicle indicates that the vehicle is in the exclusive mode, a negotiation mechanism may be used between the vehicle and the management device, to change the mode identifier information. For example, when the vehicle receives the fourth vehicle usage notification message and the fourth vehicle usage notification message includes the identity information of the non-single user and the driving route plan of the non-single user, if the vehicle is idle at this moment, the vehicle may respond to the driving route plan of the non-single user, and send a response message to the management device to provide the vehicle for a new user to use, or if the vehicle is currently occupied, the vehicle may choose to reject a request of the new user, and send a rejection message to the management device. Certainly, as a management device that has highest permission in the ITS, in some special emergency cases, the management device may compellingly schedule a vehicle. For example, the management device compellingly schedules a vehicle in the exclusive mode to a dense crowd area. That is, herein, even though the vehicle sends the rejection message, the management device may compel the vehicle. This is not limited. 
     It should be noted that the management device in the ITS learns of the mode identifier information of the vehicle. If there is no special or emergent case, the management device may schedule the vehicle according to the mode identifier information of the vehicle. Certainly, it is also possible that the management device compelling changes the mode identifier information of the vehicle in an emergency case. 
     Therefore, according to the vehicle management method in this embodiment of the present disclosure, the vehicle receives the vehicle scheduling message sent by the management device according to the mode identifier information, and performs the usage control according to the vehicle scheduling message such that the management device can dynamically adjust the vehicle resource. 
     With reference to  FIG. 4 , the following describes a vehicle management method according to an embodiment of the present disclosure.  FIG. 4  shows a schematic diagram of an interaction example of the method according to this embodiment of the present disclosure. It should be noted that this is merely intended to help a person skilled in the art better understand this embodiment of the present disclosure, but are not intended to limit the scope of this embodiment of the present disclosure. As shown in  FIG. 4 , a management center may be the management center  15  in  FIG. 1 , a vehicle is one of the vehicles  16  in  FIG. 1 , a first user is another user other than a second user, and the second user is a current user of the vehicle. The method includes the following steps. 
     Step S 401 . The vehicle receives mode identifier information set by the second user, where the mode identifier information indicates whether the vehicle is in a sharing mode. 
     The vehicle receives the mode identifier information set by the second user. Herein, description is provided using an example that the second user sets a status of the vehicle to the sharing mode. 
     Step S 402 . The vehicle sends the mode identifier information to the management center. 
     After the vehicle sends the mode identifier information to the management center, the management center receives the mode identifier information sent by the vehicle. 
     Step S 403 . The management center determines that a vehicle resource set corresponding to the vehicle is a shared vehicle resource set. 
     Herein, the management center classifies the vehicle into the shared vehicle resource set. Certainly, if the mode identifier information indicates that the vehicle is in an exclusive mode, the management center adds the vehicle into an exclusive vehicle resource set. Herein, a shared vehicle resource set corresponding to the sharing mode is used as an example for description. 
     Step S 404 . The management center receives a request message sent by the first user. 
     The first user is another user other than the current user of the vehicle. The first user sends, to the management center, a vehicle usage request message attached with identity authentication information and a driving plan of the first user. 
     Step S 405 . The management center determines that driving plans match. 
     Herein, the management center determines that the driving plan of the first user matches a driving plan of the second user such that the first user may be picked up, or the route may be modified within an acceptable range. 
     Step S 406 . The management center sends a notification message to the vehicle. 
     The management center sends the notification message to the vehicle. The notification message carries the identity authentication information and the driving plan of the first user. 
     Step S 407 . The vehicle determines a driving plan after determining an identity of the first user. 
     After receiving the notification message from the management center, the vehicle needs to confirm the identity of the first user. After the identity or permission of the first user is confirmed, the first user and the second user are allowed to share the vehicle. The vehicle adjusts the driving plan, or is driven according to an original route. 
     Optionally, in step S 408 , the management center may also determine the mode identifier information. 
     Herein, description is provided using an example that the vehicle is set to the sharing mode according to the mode identifier information. When the vehicle is set to the exclusive mode according to the mode identifier information (not shown in the figure), processing may be performed with reference to the foregoing method in the exclusive mode. Details are not described herein again. 
     It should be understood that the first user and the second user are merely examples for description herein. The method in this embodiment of the present disclosure is also applicable to an actual application in which more users share a vehicle resource in order to meet a vehicle service requirement of each user. Therefore, the management center determines, according to the mode identifier information of the vehicle, the vehicle resource set corresponding to the vehicle, and schedules the vehicle according to the vehicle resource set corresponding to the vehicle such that the first user and the second user can share the vehicle in order to flexibly allocate the vehicle. 
     It should be understood that sequence numbers of the foregoing processes do not mean execution sequences in various embodiments of the present disclosure. The execution sequences of the processes should be determined according to functions and internal logic of the processes, and should not be constructed as any limitation on the implementation processes of the embodiments of the present disclosure. 
     The foregoing describes in detail the vehicle management method according to this embodiment of the present disclosure, and the following describes a vehicle management apparatus according to an embodiment of the present disclosure. 
       FIG. 5  shows a schematic block diagram of a vehicle management apparatus  500  according to an embodiment of the present disclosure. The apparatus may be a management center or a control center of an ITS, another device that has a function of centrally controlling an ITS system, or the like. As shown in  FIG. 5 , the apparatus  500  includes an obtaining module  510  configured to obtain mode identifier information of a vehicle, where the mode identifier information indicates whether the vehicle is in a sharing mode or an exclusive mode, the sharing mode indicates that different users are allowed to share the vehicle, and the exclusive mode indicates that only a single user is allowed to use the vehicle, and a scheduling module  520  configured to schedule the vehicle according to the mode identifier information obtained by the obtaining module  510 . 
     According to the vehicle management apparatus in this embodiment of the present disclosure, a management center schedules the vehicle according to the mode identifier information of the vehicle in order to dynamically adjust a vehicle resource. 
     In this embodiment of the present disclosure, the obtained mode identifier information may be sent by the vehicle or set by the management center for the vehicle.

     Optionally, in another embodiment, the obtaining module  510  is configured to generate the mode identifier information according to vehicle usage information of an ITS. 
     Optionally, the apparatus further includes a sending module configured to set the mode identifier information for the vehicle. 
     Optionally, the scheduling module  520  is configured to determine that the vehicle resource set corresponding to the vehicle is a shared vehicle resource set when the mode identifier information indicates that the vehicle is in the sharing mode. 
     Optionally, the scheduling module  520  is configured to obtain a driving route plan of a usage to-be-allowed user when the mode identifier information indicates that the vehicle is in the sharing mode, where the usage to-be-allowed user is another user other than a usage allowed user, and the usage allowed user is a user that has been allowed to use the vehicle, and send a first vehicle usage notification message to the vehicle when a driving route plan of the usage allowed user matches the driving route plan of the usage to-be-allowed user, where the first vehicle usage notification message includes identity information of the usage to-be-allowed user and the driving route plan of the usage to-be-allowed user in order to instruct the vehicle to execute a command that is input by the user and that is corresponding to the driving route plan of the user.
