     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A mode (embodiment) for carrying out the present invention will be described in detail with reference to the drawings. The present invention is not limited by contents described in the following embodiment. In addition, constituent elements described below include constituent elements that can be easily assumed by those skilled in the art and constituent elements that are substantially the same. Further, configurations described below can be appropriately combined. In addition, various omissions, substitutions, or changes of the configurations can be made within a scope not departing from a gist of the present invention. 
     Embodiment 
     A vehicle system  100  according to an embodiment will be described with reference to the drawings.  FIG. 1  is a block diagram illustrating a configuration example of the vehicle system  100  according to the embodiment.  FIG. 2  is a view illustrating types of odors according to the embodiment. The vehicle system  100  is a system that suppresses remaining of an odor in the interior of a vehicle V for vehicle allocation. The vehicle V for vehicle allocation is, for example, an autonomously driving car such as a ride-sharing car, a bus, and a taxi. As illustrated in  FIG. 1 , the vehicle system  100  includes a management center M, a cleaning center N, and the vehicle V for vehicle allocation. 
     The management center M is a facility that manages the autonomously driving vehicles V such as ride-sharing cars, buses, and taxis, and allocates the vehicle V according to a request. The management center M registers the plurality of vehicles V in an identifiable manner, and manages states of the respective vehicles V. The management center M is connected to these vehicles V by wireless communication and can transmit and receive information to and from the vehicle V. 
     For example, when the management center M receives a request from a user who wants to use the vehicle V, the management center M dispatches the vehicle V to the user of the vehicle V by autonomous driving. In addition, when the allocated vehicle V becomes stained due to an odor, the management center M receives cleaning request information from the vehicle V. Here, the cleaning request information is information that requests cleaning of the vehicle V at the cleaning center N because it is difficult for the host vehicle V to deodorize the odor of a stain. The management center M is connected to the cleaning center N communicably and can transmit and receive information to and from the cleaning center N. When receiving the cleaning request information from the vehicle V, the management center M transmits cleaning reservation information indicating a reservation of cleaning of the vehicle V to the cleaning center N. In addition, the management center M can receive substitute vehicle request information from the allocated vehicle V. Here, the substitute vehicle request information is information indicating a request for a substitute vehicle in place of the host vehicle V. When the management center M receives the substitute vehicle request information from the vehicle V, the management center M dispatches an unallocated vehicle V to the vehicle V from which the substitute vehicle request information has been transmitted by autonomous driving. 
     The cleaning center N is a facility that cleans the vehicle V. The cleaning center N is connected to the management center M communicably and can transmit and receive information to and from the management center M. The cleaning center N can receive cleaning reservation information indicating a reservation for cleaning of the vehicle V from the management center M. When receiving the cleaning reservation information, the cleaning center N cleans the vehicle V based on the cleaning reservation information. 
     The vehicle V for vehicle allocation includes a speaker S, a display D, a power window P as an odor deodorizing device, a traveling system actuator Q, and an in-vehicle device  1 . 
     The speaker S converts an electrical signal into sound. The speaker S is provided in the interior of the vehicle V so as to be capable of outputting the sound, and is connected to the in-vehicle device  1 . The speaker S converts voice data output from the in-vehicle device  1  into a sound wave (voice) and outputs the converted sound data to the interior of the vehicle V. The speaker S, for example, converts pre-registered voice data into a sound wave (voice) and outputs the converted sound data to the interior of the vehicle V. The voice data recorded in advance has, for example, a content to notify that ventilation is performed in order to deodorize the odor in the interior of the vehicle V, and is registered in a voice registration unit  21  to be described later. An occupant of the vehicle V can notice the ventilation of the odor in the interior of the vehicle V by hearing the voice output from the speaker S. 
     The display D is a display that displays information. The display D is provided so as to be visually recognizable by the occupant of the vehicle V, and is connected to the in-vehicle device  1 . The display D displays character data output from the in-vehicle device  1  as an image (a moving image or a still image). This image, for example, has a content to notify that ventilation is performed in order to deodorize the odor in the interior of the vehicle V, and is stored in advance in a character registration unit  23  to be described later. The occupant of the vehicle V can notice the ventilation of the odor in the interior of the vehicle V by visually recognizing the image displayed on the display D. 
     The power window P is a device that raises and lowers a window glass forming a boundary between the interior and the exterior of the vehicle V. The power window P can raise and lower the window glass by an operation of the occupant. In addition, the power window P is connected to the in-vehicle device  1  and can raise and lower the window glass under the control of the in-vehicle device  1 . The power window P can communicate the interior space of the vehicle V with the exterior space by lowering the window glass, and can replace interior air of the vehicle V with exterior air. On the other hand, the power window P can block the interior space from the exterior space of the vehicle V by raising the window glass, and can confine interior air of the vehicle V to the interior. 
     The traveling system actuator Q makes the vehicle V travel. The traveling system actuator Q includes a drive unit such as an engine and a traveling motor, and a drive train (for example, a transmission, a drive shaft, or the like) that transmits the power of the drive unit to wheels. The traveling system actuator Q is connected to an operation decision unit  60 , and makes the vehicle V travel based on a drive signal output from the operation decision unit  60 . 
     The in-vehicle device  1  is a device that prevents the odor from remaining in the interior of the vehicle V. As illustrated in  FIG. 1 , the in-vehicle device  1  includes a communication device  10 , a notification processor  20 , an odor processor  30 , an imaging unit  40 , an image processor  50 , and the operation decision unit  60 . 
     The communication device  10  is a device capable of communicating with a communication network outside the vehicle V. The communication device  10  communicates with the management center M via, for example, an external communication network. The communication device  10  is connected to the operation decision unit  60 , and transmits information indicating a measure of the vehicle V determined by the operation decision unit  60  to the management center M. For example, the communication device  10  transmits, to the management center M, the cleaning request information indicating that it is difficult for the host vehicle V to deodorize the odor and requesting the cleaning center N for cleaning of the vehicle V. In addition, the communication device  10  outputs information received from the management center M (for example, substitute vehicle arrangement information) to the operation decision unit  60 . 
     The notification processor  20  processes a content that the occupant of the vehicle V is notified of. The notification processor  20  includes the voice registration unit  21 , an output voice determination unit  22 , the character registration unit  23 , and an output character determination unit  24 . 
     The voice registration unit  21  is a non-volatile memory storing information. In the voice registration unit  21 , a plurality of pieces of voice data representing that, for example, ventilation is performed to deodorize the odor in the interior of the vehicle V, that a substitute vehicle has been arranged, and the like are registered in advance. The voice registration unit  21  is connected to the output voice determination unit  22 , and the output voice determination unit  22  selects specific voice data from among the plurality of pieces of voice data. 
     The output voice determination unit  22  determines voice data to be output to the interior of the vehicle V. The output voice determination unit  22  is connected to the operation decision unit  60 , and determines specific voice data from among the plurality of pieces of voice data registered in the voice registration unit  21  based on the measure determined by the operation decision unit  60 . The output voice determination unit  22  is connected to the speaker S, and outputs the determined specific voice data to the speaker S. 
     The character registration unit  23  is a non-volatile memory storing information. In the character registration unit  23 , a plurality of pieces of character data representing that, for example, ventilation is performed to deodorize the odor in the interior of the vehicle V, that a substitute vehicle has been arranged, and the like are registered in advance. The character registration unit  23  is connected to the output character determination unit  24 , and the output character determination unit  24  selects specific character data from among the plurality of pieces of character data. 
     The output character determination unit  24  determines character data to be displayed in the interior of the vehicle V. The output character determination unit  24  is connected to the operation decision unit  60 , and determines specific character data from among the plurality of pieces of character data registered in the character registration unit  23  based on the measure determined by the operation decision unit  60 . The output character determination unit  24  is connected to the display D, and outputs the determined specific character data to the display D. 
     The odor processor  30  includes an odor sensor  31  and an odor type determination unit  32 . The odor sensor  31  is a sensor that is mounted on the vehicle V and detects the odor in the interior of the vehicle V. The odor sensor  31  is installed on the ceiling, a seat, or the like in the interior of the vehicle V. The odor sensor  31  is, for example, a crystal oscillator type sensor. In this crystal oscillator type sensor, a film that reacts to an odor is provided on a surface of the crystal oscillator. When an odorous substance adheres to the film, a frequency of the crystal oscillator changes to detect an odor component. The odor sensor  31  detects, for example, ammonia, hydrogen sulfide, methyl sulfide, and the like as the odor components. The odor sensor  31  also detects the concentration of the odorous substance based on the amount of the odorous substance adhering to the film. The odor sensor  31  is connected to the odor type determination unit  32 , and outputs the detected odor component and its concentration to the odor type determination unit  32 . 
     The odor type determination unit  32  determines a type of the odor. The odor type determination unit  32  is connected to the odor sensor  31  and determines the type of the odor based on the odor component and its concentration detected by the odor sensor  31 . Here, a table illustrating a relationship between an odor component (including a concentration of the odor component) and a type of an odor is stored in a storage unit (not illustrated), for example, as illustrated in  FIG. 2 . The odor type determination unit  32  refers to the table stored in this storage unit, and determines the type of the odor based on the odor component (including the concentration of the odor component) detected by the odor sensor  31 . The odor type determination unit  32  determines, for example, that the type of the odor is an “excreta odor” when the odor component contains an A component, a C component, an E component, and the like at a predetermined concentration. In addition, the odor type determination unit  32  determines that the type of the odor is a “coffee odor” when the odor component contains a D component, an F component, and the like at a predetermined concentration. Then, the odor type determination unit  32  determines that the intensity of the odor is relatively strong when the overall concentration of the odor components is relatively high, and determines that the intensity of the odor is relatively weak when the overall concentration of the odor components is relatively low. The odor type determination unit  32  is connected to the image processor  50 , and outputs the determined odor type and the intensity thereof to the image processor  50 . 
     The imaging unit  40  is a camera that captures an image (a moving image or a still image). One or a plurality of the imaging units  40  are installed in the interior of the vehicle V to capture the interior of the vehicle V. One or the plurality of imaging units  40  are set to have an angle of view capable of capturing the entire interior of the vehicle V. While the vehicle V is in use, the imaging unit  40  captures the interior of the vehicle V regardless of whether the vehicle V is traveling or being stopped. The imaging unit  40  is connected to the image processor  50  and outputs the captured image to the image processor  50 . 
     The image processor  50  processes the image. The image processor  50  includes an occupant detection unit  51  and a stain identification unit  52 . 
     The occupant detection unit  51  detects the occupant in the vehicle V based on the image. The occupant detection unit  51  detects an occupant using, for example, a well-known image recognition technique such as a pattern recognition technique for recognizing an object based on a feature of an image. The occupant detection unit  51  is connected to the imaging unit  40 , and detects the presence or absence of the occupant in the vehicle V based on the image of the interior of the vehicle V captured by the imaging unit  40 . The occupant detection unit  51  is connected to the operation decision unit  60 , and outputs detected occupant detection information indicating the presence or absence of the occupant to the operation decision unit  60 . 
     The stain identification unit  52  identifies an object generating an odor. The stain identification unit  52  is connected to the odor processor  30  and the imaging unit  40 , and identifies the object generating the odor based on the type and intensity of the odor output from the odor processor  30  and the interior image output from the imaging unit  40 . 
     For example, in the case where the type of the odor is the excreta odor, the stain identification unit  52  identifies the object generating the odor is a stain representing excreta when the stain representing the excreta is detected from the interior image. In addition, for example, in the case where the type of the odor is the coffee odor, the stain identification unit  52  identifies that the object generating the odor is a stain generated by spilled coffee when the stain generated by spilled coffee is detected from the interior image. On the other hand, in the case where the type of the odor is the coffee odor, the stain identification unit  52  identifies that the coffee odor is not an odor to be deodorized when an occupant drinking coffee is detected from the interior image rather than the stain generated by spilled coffee. The stain identification unit  52  is connected to the operation decision unit  60 , and outputs odorous object information representing the object generating the odor to the operation decision unit  60 . 
     The operation decision unit  60  decides an operation of the vehicle V based on the odorous object information output from the stain identification unit  52 . When deciding that the interior odor can be deodorized by the host vehicle V based on the odorous object information, the operation decision unit  60  deodorizes the interior odor by the host vehicle V. On the other hand, when deciding that it is difficult to deodorize the interior odor by the host vehicle V based on the odorous object information, the operation decision unit  60  deodorizes the odor at an external facility. 
     For example, the odorous object information represents a coffee odor (stain) and it has been decided that the interior odor can be deodorized by the host vehicle V, the operation decision unit  60  performs a first operation of driving the power window P of the host vehicle V to deodorize the interior odor. In this case, the operation decision unit  60  drives, for example, the power window P to lower the window glass such that the interior space of the vehicle V and the exterior space communicate with each other, ventilates the vehicle V by replacing the interior air with the exterior air to deodorize the coffee odor in the interior. 
     In addition, when it has been decided that the odorous object information represents the excreta odor and it is difficult for the host vehicle V to deodorize the interior odor, the operation decision unit  60  transmits the cleaning request information to the management center M via the communication device  10 . Then, when it is difficult for the host vehicle V to deodorize the interior odor, the operation decision unit  60  performs a second operation of transmitting a drive signal to the traveling system actuator Q to drive the traveling system actuator Q to direct the host vehicle V to the external cleaning center N. At this time, the operation decision unit  60  determines the presence or absence of an occupant existing in the interior based on the occupant detection information output from the occupant detection unit  51 . Then, when there is the occupant in the interior, the operation decision unit  60  requests the external management center M for a substitute vehicle to replace the host vehicle V via the communication device  10 . The operation decision unit  60  transmits, for example, the substitute vehicle request information for requesting a substitute vehicle to the management center M via the communication device  10 . On the other hand, the operation decision unit  60  decides not to request the external management center M for the substitute vehicle to replace the host vehicle V via the communication device  10  when there is no occupant in the interior. That is, the operation decision unit  60  does not transmit the substitute vehicle request information requesting the substitute vehicle to the management center M via the communication device  10 . 
     Next, an operation example of the vehicle system  100  will be described.  FIG. 3  is a flowchart illustrating the operation example of the vehicle system  100  according to the embodiment. As illustrated in  FIG. 3 , in the vehicle system  100 , the odor sensor  31  of the allocated vehicle V detects the odor in the interior of the vehicle V (Step S 1 ). The odor sensor  31  repeats the process of detecting the odor when no odor in the interior of the vehicle V is detected (Step S 1 ; No). When detecting the odor in the interior of the vehicle V (Step S 1 ; Yes), the odor sensor  31  outputs the detected odor component and its concentration to the odor type determination unit  32 . 
     The odor type determination unit  32  determines the type of the odor and the intensity thereof based on the odor component and its concentration output by the odor sensor  31  (Step S 2 ). The odor type determination unit  32  refers to  FIG. 2 , for example, and determines that the type of the odor is the “coffee odor” when the odor component contains the D component, the F component, and the like at a predetermined concentration. Then, the odor type determination unit  32  determines that the intensity of the odor is relatively strong when the overall concentration of the odor components is relatively high, and determines that the intensity of the odor is relatively weak when the overall concentration of the odor components is relatively low. Next, the stain identification unit  52  identifies the object generating the odor based on the type (including the intensity) of the odor determined by the odor type determination unit  32  and the interior image captured by the imaging unit  40  (Step S 3 ). For example, in the case where the type of the odor is the coffee odor, the stain identification unit  52  identifies that the object generating the odor is a stain generated by spilled coffee when the stain generated by spilled coffee is detected from the interior image. 
     Next, the operation decision unit  60  determines whether or not the occupant is present in the interior based on the occupant detection information output from the occupant detection unit  51  (Step S 4 ). When the occupant is present in the interior (Step S 4 ; Yes), the operation decision unit  60  determines whether or not deodorization can be performed by the host vehicle V (Step S 5 ). When the deodorization can be performed by the host vehicle V in the case where the occupant is present in the interior (Step S 5 ; Yes), the operation decision unit  60  notifies the occupant that ventilation is to be performed to deodorize the odor in the vehicle V (Step S 6 ). For example, the operation decision unit  60  controls the notification processor  20 , outputs a voice representing a content indicating that the ventilation is to be performed from the speaker S, and displays an image representing the content indicating that the ventilation is to be performed on the display D. Next, the operation decision unit  60  performs ventilation processing (Step S 7 ). The operation decision unit  60  drives, for example, the power window P to lower the window glass such that the interior space of the vehicle V and the exterior space communicate with each other, ventilates the vehicle V by replacing the interior air with the exterior air, and ends the processing. 
     In Step S 5  above, the operation decision unit  60  notifies the management center M (Step S 8 ) when the occupant is present in the interior and it is difficult for the host vehicle V to perform deodorization (Step S 5 ; No). The operation decision unit  60  transmits, for example, the cleaning request information requesting the cleaning center N for cleaning the vehicle V and the substitute vehicle request information indicating the request for the substitute vehicle to the management center M. When receiving the cleaning request information from the vehicle V, the management center M transmits cleaning reservation information indicating a reservation of cleaning the vehicle V to the cleaning center N. In addition, when receiving the substitute vehicle request information from the vehicle V, the management center M dispatches an unallocated vehicle V to the vehicle V to which the substitute vehicle request information has been transmitted by autonomous driving (Step S 9 ). 
     Next, the operation decision unit  60  notifies the occupant of transfer (Step S 10 ). The operation decision unit  60  controls, for example, the notification processor  20  to output a voice representing the transfer to the substitute vehicle from the speaker S, and to display an image representing the transfer to the substitute vehicle on the display D. Next, the operation decision unit  60  moves the vehicle V to the cleaning center N (Step S 11 ). For example, the operation decision unit  60  transmits a drive signal to the traveling system actuator Q to drive the traveling system actuator Q, directs the host vehicle V to the cleaning center N, and ends the processing. 
     When the occupant is not present in the interior in Step S 4  (Step S 4 ; No), the operation decision unit  60  determines whether or not deodorization can be performed by the host vehicle V (Step S 12 ). The operation decision unit  60  performs ventilation processing (Step S 13 ) when the occupant is not present in the interior and the deodorization can be performed by the host vehicle V (Step S 12 ; Yes). The operation decision unit  60  drives, for example, the power window P to lower the window glass such that the interior space of the vehicle V and the exterior space communicate with each other, ventilates the vehicle V by replacing the interior air with the exterior air, and ends the processing. The operation decision unit  60  notifies the management center M (Step S 14 ) when the occupant is not present in the interior and it is difficult for the host vehicle V to perform deodorization (Step S 12 ; No). The operation decision unit  60  transmits, for example, the cleaning request information requesting the cleaning center N for cleaning the vehicle V to the management center M. Since the occupant is not present in the interior, the operation decision unit  60  does not request the substitute vehicle. When receiving the cleaning request information from the vehicle V, the management center M transmits cleaning reservation information indicating a reservation of cleaning the vehicle V to the cleaning center N. Next, the operation decision unit  60  moves the vehicle V to the cleaning center N (Step S 15 ). For example, the operation decision unit  60  transmits a drive signal to the traveling system actuator Q to drive the traveling system actuator Q, directs the host vehicle V to the cleaning center N, and ends the processing. 
     As described above, the in-vehicle device  1  according to the embodiment includes the odor sensor  31 , the odor type determination unit  32 , and the operation decision unit  60 . The odor sensor  31  is mounted on the vehicle V and detects the odor in the interior of the vehicle V. The odor type determination unit  32  determines the type of the odor detected by the odor sensor  31 . The operation decision unit  60  decides the operation of the vehicle V based on the type of the odor determined by the odor type determination unit  32 . With this configuration, the in-vehicle device  1  can cause the vehicle V to perform an appropriate operation according to the type of the odor. The in-vehicle device  1  can, for example, perform deodorization by the vehicle V or move the vehicle V to the cleaning center N according to the type of the odor. As a result, there is a case where the in-vehicle device  1  can perform deodorization without cleaning the vehicle V depending on the type of the odor, and the efficiency of vehicle allocation is likely to deteriorate if the vehicle V is cleaned in this case. However, the deterioration in allocation efficiency is suppressed by performing deodorization by the host vehicle V. As a result, the in-vehicle device  1  can appropriately deal with the odor in the interior of the vehicle V, and can suppress the deterioration in vehicle allocation efficiency due to the odor. In addition, the in-vehicle device  1  can prevent the odor from remaining in the interior of the vehicle V, so that the occupant can get on the vehicle comfortably. In addition, since the in-vehicle device  1  notifies the management center M of a stain caused by the odor, the stain can be dealt with appropriately, and improvement in work efficiency at the time of maintaining the vehicle V can be expected. 
     In the in-vehicle device  1 , the operation decision unit  60  decides either the first operation of driving a power window P of a host vehicle V to deodorize the odor of the interior or the second operation of driving a traveling system actuator Q that makes the host vehicle V travel to direct the host vehicle V to an external cleaning center N based on the type of the odor. With this configuration, the in-vehicle device  1  can suppress the deterioration in vehicle allocation efficiency due to the odor, as the host vehicle V performs deodorization depending on the type of the odor. In addition, the in-vehicle device  1  can reliably deodorize the odor by cleaning at the cleaning center N depending on the type of the odor. 
     In the in-vehicle device  1 , the operation decision unit  60  requests the external management center M for the substitute vehicle substituting for the host vehicle V via the communication device  10  in the case where the occupant is present in the vehicle V when the second operation is decided, and decides not to request the external management center M for the substitute vehicle substituting for the host vehicle V via the communication device  10  in the case where no occupant is present in the vehicle V when the second operation is decided. With this configuration, the in-vehicle device  1  can provide another vehicle V to the occupant even if the vehicle V is directed to the cleaning center N, and can prevent the occupant from being unable to board the vehicle V. 
     The above in-vehicle device  1  further includes the imaging unit  40  that captures the interior of the vehicle V, and the operation decision unit  60  decides the operation of the vehicle V based on the image captured by the imaging unit  40  and the type of the odor determined by the odor type determination unit  32 . With this configuration, the in-vehicle device  1  can identify the object generating the odor, and can more appropriately decide the operation of the vehicle V based on the identified object. 
     Modifications 
     Note that the above description has been given regarding the example in which the vehicle V for vehicle allocation is a car that autonomously drives, but the present invention is not limited thereto, and the vehicle V may be a car driven by a driver. 
     Although the example in which the odor sensor  31  is a crystal oscillator type sensor has been described, another sensor may be used without being limited thereto. For example, the odor sensor  31  may be a semiconductor type sensor that identifies an odor component based on a change of a resistance value in a semiconductor due to the adsorption of an odorous substance on a surface of the semiconductor and the surface reaction. 
     The in-vehicle device  1  has been described with the example in which the first operation is the operation of driving the power window P of the host vehicle V to deodorize the odor in the interior based on the type of the odor, but any other operation may be performed without being limited thereto. As the first operation, the in-vehicle device  1  may drive an air purifier of the host vehicle V to deodorize the odor in the interior and may recommend the occupant to use a deodorant spray through the speaker S and the display D. 
     The in-vehicle device  1  has been described with the example in which the second operation is the operation of driving the traveling system actuator Q that makes the host vehicle V travel to direct the host vehicle V to the external cleaning center N based on the type of the odor, but any other operation may be performed without being limited thereto. As the second operation, the in-vehicle device  1  may be directed to the management center M, or may be directed to another facility (a repair shop, or the like). 
     The description has been given regarding the example in which the operation decision unit  60  requests the management center M for the substitute vehicle in the case where the occupant is present in the vehicle V when the second operation of directing the host vehicle V to the cleaning center N is decided, but the present invention is not limited thereto, and the request to the management center M for the substitute vehicle is not necessarily made. 
     The description has been given regarding the example in which the operation decision unit  60  decides the operation of the vehicle V based on the image captured by the imaging unit  40  and the type of the odor determined by the odor type determination unit  32 , but the present invention is not limited thereto. The operation of the vehicle V may be determined based on the type of the odor determined by the odor type determination unit  32  without using the image captured by the imaging unit  40 . 
     The description has been given regarding the example in which the operation decision unit  60  notifies the occupant through the speaker S and the display D, but the present invention is not limited thereto, and the notification may be issued to a mobile phone of the occupant. 
     The description has been given regarding the example in which the operation decision unit  60  is provided in the in-vehicle device  1 , but the present invention is not limited thereto, and the operation decision unit  60  may be provided in, for example, a server (cloud server) outside the vehicle V. 
     Since the in-vehicle device according to the embodiment determines an operation of the vehicle based on a type of the odor, it is possible to appropriately deal with the odor in the interior of the vehicle. 
     Although the invention has been described with respect to specific embodiments for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art that fairly fall within the basic teaching herein set forth.
