<1-4. Communication System Processing>
Next, processing of the communication system 100 will be described. 6 and 7 are diagrams illustrating a processing flow of the communication system 100. FIG. Hereinafter, the processing flow of the communication system 100 will be described by focusing on one vehicle 5. Hereinafter, the vehicle 5 of interest is referred to as “target vehicle”, and the user of the target vehicle is referred to as “target user”.
When the information providing apparatus 2 for the target vehicle is activated, first, the control unit 30 identifies the target user and acquires identification information of the target user (step S21). The control unit 30 identifies the target user based on the information regarding the target user acquired by the user monitoring device 52. The control unit 30 can identify the target user based on, for example, information on a portable device possessed by the target user, an image of the target user, or biological information of the target user.
Next, the control part 30 acquires the kind of vehicle function with which an object vehicle is provided (step S22). The control unit 30 transmits a signal to the function providing device 50 via the in-vehicle communication unit 33 to grasp what kind of vehicle function the target vehicle has. Normally, one vehicle 5 has a plurality of vehicle functions such as ACC, LKA, and snow mode. Hereinafter, the target vehicle will be described as having a plurality of different vehicle functions.
Next, the position acquisition unit 34 acquires the current position of the target vehicle based on signals from a plurality of satellites (step S23).
Next, the environment acquisition unit 30a acquires the traveling environment at the current position of the target vehicle (step S24). The environment acquisition unit 30a transmits an environment request signal for requesting a traveling environment to the server device 1. This environment request signal includes the current position of the target vehicle acquired by the position acquisition unit 34.
In response to the environment request signal, the transmission processing unit 10b of the server device 1 transmits the traveling environment to the information providing device 2 (step S11). The transmission processing unit 10b refers to the map data 15a, the traffic jam data 15b, the weather data 15c, and the like in the database 15, and acquires the road type, the presence / absence of traffic jam, the weather, and the like as the driving environment at the current position of the target vehicle. Then, the information is transmitted to the information providing apparatus 2 via the network 9. Thereby, the environment acquisition unit 30a acquires the travel environment at the current position of the target vehicle from the server device 1 via the network 9. Furthermore, the environment acquisition unit 30a acquires the current date and time as part of the traveling environment by using the timekeeping function of the server device 1 or the control unit 30.
As described above, the environment acquisition unit 30a acquires the traveling environment of the target vehicle from the server device 1 via the network 9, and thus acquires the traveling environment even if the vehicle 5 does not include a device that detects the traveling environment. Can do.
Next, the condition acquisition unit 30b acquires from the server device 1 a determination condition for determining that the use of the vehicle function included in the target vehicle is preferable. First, the condition acquisition unit 30b transmits a condition request signal for requesting a determination condition to the server device 1 (step S25). This condition request signal includes the current position of the target vehicle and identification information of a plurality of vehicle functions included in the target vehicle.
In response to this condition request signal, the condition setting unit 10c of the server device 1 sets a vehicle function determination condition provided in the target vehicle (step S12). The condition setting unit 10c selects the function-specific data 15e related to the vehicle function included in the target vehicle from the function-specific data 15e in the database 15. The condition setting unit 10c refers to the function-specific data 15e, and the users of the plurality of vehicles 5 related to the communication system 100 actually use the vehicle function in the vicinity of the current position of the target vehicle (for example, within a radius of 1 km). Statistically grasp the driving environment. In other words, the condition setting unit 10c allows the user (unspecified number of users) of a plurality of other vehicles other than the target vehicle to actually perform the vehicle function in any driving environment in the vicinity of the current position of the target vehicle. Statistically grasp whether it is used. Then, the condition setting unit 10c sets a determination condition based on the grasped traveling environment.
For example, in the case where 80% or more of the users who use the vehicle function are using the vehicle function when the road type is an expressway and there is no traffic jam, the condition setting unit 10c sets the “road type "=" Expressway "and" Congestion presence "=" None "are set. The “date and time” of the function-specific data 15e is classified into time zones such as early morning, morning, noon, evening, night, and midnight. And when there is a specific tendency in the time zone in which the users of the plurality of vehicles 5 have used the vehicle function, “time zone” is set as the determination condition.
The condition setting unit 10c sets such a determination condition for each of a plurality of vehicle functions included in the target vehicle. As a result, the condition setting unit 10c generates a determination condition table T1 as shown in FIG. The determination condition table T1 includes a plurality of determination conditions respectively corresponding to a plurality of vehicle functions included in the target vehicle. The determination condition table T1 is data in a table format and has a plurality of records Rc. Each record Rc corresponds to one vehicle function and indicates a determination condition set for the vehicle function.
In each record Rc, a “vehicle function name” for identifying the vehicle function and a driving environment (“time zone”, “road type”, “presence / absence of traffic congestion) as a determination condition for determining that the use of the vehicle function is preferable. ”,“ Weather ”, etc.). In the example of FIG. 8, the determination conditions for ACC are “road type” = “highway” and “presence of traffic jam” = “none”.
As described above, the condition setting unit 10c sets the determination condition based on the actual usage situation of the users of the plurality of vehicles 5 in the vicinity of the current position of the target vehicle. For this reason, it is possible to flexibly set appropriate judgment conditions reflecting judgment results (judgment results by humans) determined by a plurality of users in the vicinity of the current position.
Since the condition setting unit 10c sets the determination condition according to the current position of the target vehicle, the determination condition may change if the current position of the target vehicle changes. For example, when the current position of the target vehicle has moved, the determination condition for ACC may change to “road type” = “general road” and “presence of traffic jam” = “none”.
When the condition setting unit 10c generates such a determination condition table T1, the condition setting unit 10c transmits the determination condition table T1 to the information providing apparatus 2 via the network 9 (step S13). Thereby, the condition acquisition unit 30b acquires the determination condition table T1 including the respective determination conditions for the plurality of vehicle functions included in the target vehicle from the server device 1 via the network 9 (step S26).
Thereafter, based on the travel environment of the target vehicle acquired by the environment acquisition unit 30a and the determination condition table T1 acquired by the condition setting unit 10c, the suitability determination unit 30c uses each of the plurality of vehicle functions included in the target vehicle. Judge whether it is preferable.
First, the suitability determination unit 30c selects one of a plurality of vehicle functions included in the target vehicle as a “target function” to be determined (step S27 in FIG. 7).
Next, the suitability determination unit 30c determines whether or not the traveling environment of the target vehicle satisfies the determination condition for the target function included in the determination condition table T1 (step S28). For example, when the target function is ACC and the determination condition table T1 is as shown in FIG. 8, the driving environment of the target vehicle is “road type” = “highway”, “congestion presence / absence” = “none”. The suitability determination unit 30c determines whether or not the determination condition is satisfied.
If the traveling environment of the target vehicle does not satisfy the determination condition for the target function (No in step S28), the suitability determination unit 30c determines that the use of the target function is not preferable, and the process proceeds directly to step S35.
On the other hand, when the traveling environment of the target vehicle satisfies the determination condition for the target function (Yes in step S28), the suitability determination unit 30c determines that the use of the target function is preferable. In this case, subsequently, the user determination unit 30d executes a user determination process (step S29) to determine whether or not to suggest the use of the target function to the target user.
If the use of the vehicle function is preferred and the user is suggested to use it uniformly, there are users who feel that such a proposal is troublesome. On the other hand, there are some users who do not know the operation method of the vehicle function or forget to actively propose the use of the vehicle function because they forgot. For this reason, in the user determination process (step S29), the user determination unit 30d proposes the target user to use the target function based on the past usage situation regarding the target function of the target user so as to meet the target user's request. It is determined whether or not.
FIG. 9 is a diagram showing a detailed flow of the user determination process (step S29).
First, the user determination unit 30d acquires user-specific data 15d representing the past usage status related to the target function of the target user from the server device 1 (step S41). The condition acquisition unit 30b transmits a data request signal for requesting the user-specific data 15d to the server device 1. The data request signal includes the identification information of the target user acquired in step S21 of FIG.
In response to this data request signal, the transmission processing unit 10b of the server device 1 transmits the user-specific data 15d of the target user to the information providing device 2 via the network 9 (step S15). As a result, the user determination unit 30d acquires the user-specific data 15d from the server device 1 via the network 9.
Next, the user determination unit 30d refers to “user correspondence” in the record Ra of the target function in the user-specific data 15d (see FIG. 4), and determines whether or not the latest correspondence of the target user regarding the target function is “denied”. It is determined whether or not (step S42).
When the response of the latest target user regarding the target function is “denied” (Yes in step S42), it is considered that the target user does not want to use the target function. Therefore, in principle, the user determination unit 30d determines that the proposal for using the target function is “unnecessary” (step S47).
However, when a relatively long time (for example, half a year) has passed since the last time the target user was handled, it is possible that the target user is changed and desires to use the target function. For this reason, when the first threshold time (for example, half a year) has elapsed since the last time the target user was handled (Yes in step S43), the user determination unit 30d proposes the use of the target function. It is judged as “necessary” (step S46).
If the response of the latest target user related to the target function is not “denied” (No in step S42), the user determination unit 30d then sets the response of the latest target user related to the target function to “use”. Is determined (step S44).
When the response of the latest target user regarding the target function is “use” (Yes in step S44), since the target user has experience in using the target function, the target user who wants to use the target function is spontaneous It is considered that the target function is used by operating the operation unit. Therefore, in principle, the user determination unit 30d determines that the proposal for using the target function is “unnecessary” (step S48).
However, when a certain amount of time (for example, one month) has elapsed since the last time the target user was handled, the target user may forget the operation method of the target function. For this reason, when the second threshold time (for example, one month) has elapsed since the last time the target user was handled (Yes in step S45), the user determination unit 30d proposes the use of the target function. Is determined to be “necessary” (step S46).
In addition, when the response of the latest target user regarding the target function is neither “denial” nor “use” (No in step S44), it is considered that the target user has no experience in using the target function. In this case, in order for the target user to experience the convenience of the target function, the user determination unit 30d determines that the proposal for using the target function is “necessary” (step S46).
As described above, the user determination unit 30d determines whether or not to suggest the use of the target function to the target user based on the past usage situation regarding the target function of the target user. For this reason, according to the request | requirement of an object user, it can be determined appropriately whether it proposes to an object user.
Returning to FIG. 7, when the user determination process (step S29) is completed, a process according to the determination result of the user determination process is performed. If it is determined that the use of the target function is “unnecessary” in the user determination process (No in step S30), the use of the target function is not proposed, and the process directly proceeds to step S35.
On the other hand, when it is determined that the use of the target function is “necessary” in the user determination process (Yes in step S30), the user proposing unit 30e proposes the use of the target function to the target user (step S31). In this case, the user proposing unit 30e controls the information output unit 32 to display a message for proposing use of the target function on the screen of the display 21 as shown in FIG. At this time, it is desirable to output a predetermined sound from the speaker in accordance with the message display.
In addition, two command buttons, an approval button 21a and a denial button 21b, are further displayed on the screen of the display 21. The target user touches one of these two command buttons. Thereby, the target user can approve or deny the use of the target function in response to the proposal of the use of the target function.
When the target user approves the use of the target function (Yes in step S32), the function execution unit 30f transmits a predetermined signal to the function providing device 50 that provides the target function via the in-vehicle communication unit 33. The target function is executed (step S33). Therefore, the target user can easily execute the target function only by approving in response to the proposal. Subsequently, the control unit 30 transmits usage status data indicating that the target function has been used to the server device 1 via the network 9 (step S34).
On the other hand, when the target user denies the use of the target function (No in step S32), the function execution unit 30f does not execute the target function, and the use indicating that the control unit 30 denies the proposal of the target function The situation data is transmitted to the server device 1 via the network 9 (step S34).
The usage status data transmitted in this way is received by the server device 1. The reception processing unit 10a of the server device 1 updates the contents of the user-specific data 15d and the function-specific data 15e in the database 15 to reflect the contents of the received usage status data (step S14).
When the process related to one vehicle function is completed in this way, the suitability determination unit 30c determines whether there is a vehicle function that is not set as the target function among the plurality of vehicle functions included in the target vehicle (step S35). . If it exists (Yes in step S35), the process returns to step S27, the next one of the plurality of vehicle functions is selected as a new target function, and the target function is the same as described above. It is determined whether or not the use of is preferable. Such processing is repeated, and it is determined whether or not the use is preferable for all the vehicle functions included in the target vehicle.
When it is determined whether or not use is preferable for all vehicle functions (No in step S35), the process returns to step S23 in FIG. 6, the current position of the target vehicle is newly acquired, and the same process as described above. Will be repeated again.
As described above, in the information providing apparatus 2 of the present embodiment, the environment acquisition unit 30a acquires the traveling environment of the vehicle 5, and the condition acquisition unit 30b determines that it is preferable to use the vehicle function provided in the vehicle 5. Are obtained from the predetermined server device 1 via the network 9. Then, the user proposing unit 30e proposes use of the vehicle function to the user when the traveling environment satisfies the determination condition. Since it is determined whether or not the use of the vehicle function is preferable based on the determination condition acquired from the server device 1 in this way, the use of the vehicle function can be appropriately proposed.
Further, the position acquisition unit 34 acquires the current position that is the current position of the vehicle 5, the environment acquisition unit 30 a acquires the traveling environment at the current position of the vehicle 5, and the condition acquisition unit 30 b becomes the current position of the vehicle 5. Acquire the judgment condition according to. For this reason, it is possible to determine whether or not the use of the vehicle function is preferable based on the current position of the vehicle 5, and it is possible to further appropriately propose the use of the vehicle function.
In addition, the condition setting unit 10 c of the server device 1 sets the determination condition according to the usage status of the vehicle functions of the users of the plurality of vehicles 5 related to the communication system 100. For this reason, it is possible to flexibly set an appropriate determination condition that reflects the actual usage status of a plurality of users. And since it is judged whether use of a vehicle function is preferable based on the judgment conditions reflecting such an actual use condition, the proposal of use of a vehicle function can be performed further appropriately.
In addition, the user determination unit 30d determines whether or not to suggest the use of the vehicle function to the user based on the use situation of the user's vehicle function in the past. For this reason, use proposal of a vehicle function can be performed appropriately so that a user's request may be met.
Further, user-specific data 15 d representing the usage status of the user's vehicle functions in the past is stored in the server device 1, and the user determination unit 30 d acquires the user-specific data 15 d from the server device 1 via the network 9. For this reason, even when the user changes the vehicle 5, based on the user-specific data 15d stored in the server device 1, the user can be appropriately proposed to use the vehicle function. .
Next, a second embodiment will be described. Since the configuration and operation of the communication system 100 according to the second embodiment are substantially the same as those of the first embodiment, the following description will focus on differences from the first embodiment.
In the first embodiment, when the traveling environment satisfies any of the determination conditions for a plurality of vehicle functions, the user proposing unit 30e proposes the use of the vehicle function corresponding to the determination conditions. When the user approves the use of the vehicle function in response to the proposal, the function execution unit 30f executes the vehicle function. In contrast, in the second embodiment, when the traveling environment satisfies any of the determination conditions for a plurality of vehicle functions, when the vehicle function corresponding to the determination conditions is a specific function, the function execution unit The vehicle function 30f automatically executes the vehicle function without the user's approval.
Among a plurality of vehicle functions provided in the vehicle 5, a specific function that is automatically executed in this way is determined in advance. For example, a function for displaying images and information such as MAV is preferably a specific function. On the other hand, for example, a function that intervenes in the operation of the driver such as an accelerator and a steering wheel such as ACC is not desirably a specific function. Which of the plurality of vehicle functions included in the vehicle 5 is set as the specific function may be set by the user according to preference.
In the present embodiment, which of the plurality of vehicle functions included in the vehicle 5 is the specific function is determined by the determination condition table acquired from the server device 1 by the condition acquisition unit 30b.
FIG. 11 is a diagram illustrating an example of the determination condition table T2 according to the second embodiment. The judgment condition table T2 of the present embodiment is also data in a table format and has a plurality of records Rc. Each record Rc corresponds to one vehicle function and indicates a determination condition set for the vehicle function. At the same time, each record Rc has an item “specific function”, and “Yes” or “No” is registered in “specific function”. The vehicle function of the record Rc in which “Yes” is registered in the “specific function” is the specific function.
The processing flow of the communication system 100 according to the second embodiment is that after the user determination process determines that the use of the target function is “necessary” (Yes in step S30 in FIG. 7), This is partly different from the first embodiment. FIG. 12 mainly shows a part of the processing flow of the communication system 100 according to the second embodiment that is different from the first embodiment.
When it is determined that the use of the target function is “necessary” in the user determination process (Yes in step S30), the function execution unit 30f determines whether the target function is a specific function (step S301). ). This target function corresponds to a vehicle function corresponding to a determination condition that satisfies the traveling environment. The function execution unit 30f refers to the determination condition table T2 and determines whether or not the target function is a specific function.
If the target function is not a specific function (No in step S301), the user proposing unit 30e proposes the use of the target function to the target user as in the first embodiment (step S31). If the target user approves the use of the target function (Yes in step S32), the function execution unit 30f executes the target function (step S33).
On the other hand, when the target function is a specific function (Yes in step S301), the proposal to the target user by the user proposal unit 30e is omitted, and the function execution unit 30f can execute the target function without the user's approval. Is automatically executed (step S33).
When the function execution unit 30f automatically executes the target function without user approval as described above, the function execution unit 30f controls the information output unit 32 and automatically executes the target function as shown in FIG. A message indicating that it has been displayed is displayed on the screen of the display 21. At this time, it is desirable to output a predetermined sound from the speaker in accordance with the message display.
In addition, two command buttons, an OK button 21c and a cancel button 21d, are further displayed on the screen of the display 21. The target user can stop the execution of the automatically executed target function by touching the cancel button 21d of these two command buttons.
As described above, in the second embodiment, when it is determined that the use of a certain vehicle function is preferable, the function execution unit 30f, when the vehicle function is a specific function, the vehicle without the user's approval. Perform the function automatically. For this reason, the burden of a user's operation can be reduced significantly.
Next, a third embodiment will be described. Since the configuration and operation of the communication system 100 according to the third embodiment are substantially the same as those of the first embodiment, the following description will focus on differences from the first embodiment.
In the first embodiment, it is determined whether or not it is preferable to use the vehicle function at the current position of the vehicle 5. In contrast, in the third embodiment, a planned position, which is a position where the vehicle 5 is scheduled to travel, is derived, and it is determined whether or not it is preferable to use the vehicle function at the planned position of the vehicle 5. It has become.
FIG. 14 is a diagram mainly illustrating a configuration of the information providing apparatus 2 according to the third embodiment. The information providing apparatus 2 according to the third embodiment includes a position deriving unit 30g as one of the functions of the control unit 30 realized by executing the program 35a. Other configurations are the same as those of the first embodiment.
The position deriving unit 30g derives a planned position that is a position where the vehicle 5 is scheduled to travel. The position deriving unit 30g uses the current position of the vehicle 5, the route to the destination, and the speed of the vehicle 5 to determine the position where the vehicle 5 is scheduled to travel after a predetermined time (for example, 10 minutes later). Derived as
The processing flow of the communication system 100 according to the third embodiment is partially different from that of the first embodiment. In the communication system 100 according to the third embodiment, the “predicted position” of the vehicle 5 is used instead of the “current position” of the vehicle 5 in the first embodiment. Therefore, the environment acquisition unit 30 a acquires the traveling environment at the predicted position of the vehicle 5, and the condition acquisition unit 30 b acquires the determination condition according to the predicted position of the vehicle 5.
FIG. 15 mainly shows a part of the processing flow of the communication system 100 according to the third embodiment that is different from the first embodiment.
First, the control unit 30 identifies the target user (step S21), and acquires the type of vehicle function included in the target vehicle (step S22).
Next, the position deriving unit 30g acquires the current position of the vehicle 5 from the position acquisition unit 34, the route from the navigation device to the destination included in the in-vehicle information device 54, and the speed of the vehicle 5 from the vehicle monitoring device 53 ( Step S231). The position deriving unit 30g derives a planned position of the vehicle 5 based on the current position of the vehicle 5, the route to the destination, and the speed of the vehicle 5 (step S232).
Next, the environment acquisition unit 30a acquires the traveling environment at the planned position of the target vehicle (step S24). The environment acquisition unit 30a transmits an environment request signal including the planned position of the target vehicle to the server device 1. Thereby, the environment acquisition unit 30a acquires the travel environment at the planned position of the target vehicle from the server device 1 via the network 9. In addition, the environment acquisition unit 30a acquires a date and time obtained by adding a predetermined time (for example, 10 minutes) to the current date and time as a part of the traveling environment.
Next, the condition acquisition unit 30b acquires a determination condition at the planned position of the target vehicle. The condition acquisition unit 30b transmits a condition request signal including the planned position of the target vehicle to the server device 1 (step S25). In response to the condition request signal, the condition setting unit 10c of the server device 1 sets a vehicle function determination condition included in the target vehicle (step S12). The condition setting unit 10c sets the determination condition based on the actual usage situation of the users of the plurality of vehicles 5 in the vicinity of the planned position of the target vehicle.
Then, the condition setting unit 10c transmits the determination condition table T1 to the information providing apparatus 2 via the network 9 (step S13). Thereby, the condition acquisition unit 30b acquires the determination condition table T1 including the respective determination conditions for the plurality of vehicle functions included in the target vehicle from the server device 1 via the network 9 (step S26).
Thereafter, based on the travel environment of the target vehicle acquired by the environment acquisition unit 30a and the determination condition table T1 acquired by the condition setting unit 10c, the suitability determination unit 30c uses each of the plurality of vehicle functions included in the target vehicle. Judge whether it is preferable. Therefore, it can be determined whether or not the use of the vehicle function is preferable based on the predicted position of the vehicle 5.
As described above, in the third embodiment, since it is determined whether or not the use of the vehicle function is preferable based on the planned position of the vehicle, the use of the vehicle function can be proposed in advance. For example, prior to a situation where the use of a certain vehicle function (eg, ACC, etc.) is favorable, a user can make a suggestion to use the vehicle function. For this reason, the user can quickly use the vehicle function when the use of the vehicle function is preferable.
Hereinafter, other embodiments will be described. All the forms including the above-described embodiment and the form described below can be appropriately combined.
<4-1. User type>
The condition setting unit 10c may set the determination condition in consideration of the user type. For example, the user can be classified into types such as a skilled driver and a beginner driver. Such user types can be preset. The condition setting unit 10c sets the determination condition using only the record Rb of the same type of user as the target user from the function-specific data 15e in the database 15. According to this, since it is determined whether or not the use of the vehicle function is preferable based on the determination condition in consideration of the type of the user, the use of the vehicle function can be further appropriately proposed.
<4-2. User physical condition>
The condition setting unit 10c may set the determination condition in consideration of the physical condition of the user. For example, the user's physical condition changes every moment, such as sleepiness and fatigue. Such physical condition of the user can be acquired based on information such as a biosensor. The condition setting unit 10c sets the determination condition using only the record Rb of the user having the same physical condition as the target user from the function-specific data 15e in the database 15. According to this, since it is determined whether or not the use of the vehicle function is preferable based on the determination condition considering the physical condition of the user, the use of the vehicle function can be further appropriately proposed.
<4-3. Use of vehicle>
The condition setting unit 10 c may set the determination condition in consideration of the usage application of the vehicle 5. For example, the user uses the vehicle 5 for various uses such as leisure and business. Such usage can be acquired based on information such as a route to the destination. The condition setting unit 10c sets a determination condition using only the record Rb having the same usage as that of the target user from the function-specific data 15e in the database 15. According to this, since it is determined whether or not the use of the vehicle function is preferable based on the determination condition considering the usage application of the vehicle 5, the use of the vehicle function can be further appropriately proposed.
In the above embodiment, the information providing device 2 has been described as an in-vehicle device mounted on the vehicle 5. However, a portable information terminal such as a tablet terminal or a smartphone that the user brings into the vehicle 5 may function as the information providing device 2. .
In the above embodiment, the information providing device 2 and the electronic devices 51 to 54 are described as separate devices. However, the information providing device 2 is integrated with any one of the electronic devices 51 to 54. May be used. For example, the information providing device 2 may be integrated with a navigation device that is one of the in-vehicle information devices 54.
Moreover, in the said embodiment, the environment acquisition part 30a acquired the driving environment of the target vehicle mainly from the server apparatus 1. FIG. On the other hand, the environment acquisition unit 30a may acquire part or all of the traveling environment from an apparatus included in the target vehicle itself. For example, when the target vehicle includes a navigation device, the environment acquisition unit 30a can acquire the road type at the current position or the planned position from the navigation device. The environment acquisition unit 30a may acquire a part or all of the traveling environment from a communication device other than the predetermined server device 1. For example, the environment acquisition unit 30a can acquire the weather at the current position or the planned position from a communication device that provides weather information.
Further, the condition setting unit 10c may change the content of the proposal for using the vehicle function according to the presence or absence of a passenger in the vehicle 5. For example, if the passenger is prone to motion sickness, the use of vehicle functions related to the behavior of the vehicle 5 may not be proposed.
In addition, the function described as one block in the above embodiment is not necessarily realized by a single physical element, and may be realized by distributed physical elements. Further, the functions described as a plurality of blocks in the above embodiments may be realized by a single physical element. In addition, even if the device in the vehicle and the device outside the vehicle share processing related to any one function and exchange information by communication between these devices, the one function can be realized as a whole. Good.
In addition, all or a part of the functions described as being realized by software in the above-described embodiment may be realized by an electrical hardware circuit. Further, the function described as one block in the above-described embodiment may be realized by cooperation of software and hardware.
