In the above-described configuration, the memory unit 22 of the server device 10 prestores vehicle information for identifying the vehicle 12 to be used for overnight stays. The vehicle information includes, for each vehicle, vehicle identification information and associated vehicle owner identification information. The vehicle information is sent from the vehicle 12 to the server device 10 in response to an operation by the owner of the vehicle 12, for example. Alternatively, the vehicle information is sent to the server device 10 from an arbitrary communication terminal device operated by the owner of the vehicle 12. In the server device 10, the control unit 23 receives the vehicle information via the communication unit 21 and stores it in the memory unit 22.

Figures 4 and 5 are sequence diagrams for explaining the operation procedure of the vehicle management system in this embodiment. Figures 4 and 5 show the procedure for the linkage operation between the server device 10 and the vehicle 12. The steps relating to various information processing of the server device 10 and the vehicle 12 in Figures 4 and 5 are executed by the control unit 23 of the server device 10 and the control unit 33 of the vehicle 12, respectively. In addition, the steps relating to the transmission and reception of various information between the server device 10 and the vehicle 12 are executed by the control unit 23 of the server device 10 and the control unit 33 of the vehicle 12 transmitting and receiving information to each other via the communication units 21 and 31, respectively.

The procedure in Figure 4 is an example of the procedure when the vehicle 12 transitions to overnight stay mode when a disaster occurs.

In step S400, the server device 10 detects the occurrence of a disaster. For example, the control unit 23 detects the occurrence of a disaster by receiving disaster information via the communication unit 21 from a cloud server that distributes disaster information. Disasters include natural disasters caused by earthquakes, weather, volcanic eruptions, etc., and man-made disasters caused by accidents in transportation, factory facilities, etc., and acts of terrorism, etc.

In step S402, the server device 10 grasps the damage situation. For example, the control unit 23 grasps the damage situation by receiving information on the damage situation via the communication unit 21 from a cloud server that distributes various news information or a server of each local government. The damage situation includes information on the affected areas, the number of victims, the occupancy status of evacuation shelters in the affected areas, etc.

In step S404, the server device 10 determines areas where car camping is available based on the disaster situation. For example, the control unit 23 determines a disaster area as an area where car camping is available when the occupancy status of an evacuation shelter indicates that the shelter is not able to accommodate all the disaster victims. Alternatively, the control unit 23 may divide the disaster area into any number of unit areas, and determine one or more unit areas that are more than an arbitrary standard distance away from an evacuation shelter, that is, unit areas where it is highly likely that evacuees will have difficulty reaching the evacuation shelter, as areas where car camping is available.

In step S406, the server device 10 uses prestored vehicle information to request location information and availability from the vehicle 12 being used for overnight stays. Availability is information indicating whether the vehicle 12 is occupied by its owner for overnight stays, i.e., whether it is available for other evacuees to use for overnight stays.

In step S408, the vehicle 12 sends its own vehicle position information and availability information to the server device 10 in response to a request from the server device 10. The control unit 33 acquires the position information from the positioning unit 34 and sends it to the server device 10. The control unit 33 also outputs information from the output unit 36 prompting the owner to input whether or not the vehicle 12 will be used for sleeping in the vehicle, and receives information from the owner from the input unit 35 indicating whether or not the vehicle 12 will be used for sleeping in the vehicle. If the owner does not use the vehicle 12, the vehicle 12 is available, so the vehicle 12 sends information indicating availability to the server device 10. On the other hand, if the owner uses the vehicle 12, the vehicle 12 is not available, so the vehicle 12 sends information indicating occupancy to the server device 10.

In step S410, the server device 10 selects a vehicle for overnight stays to be used for overnight stays. The control unit 23 selects an available vehicle 12 located in an area where overnight stays are available as a vehicle for overnight stays based on the location information and availability of the vehicle 12. Furthermore, the control unit 23 may set a condition for identifying a vehicle 12 as an overnight stay vehicle that the vehicle 12 is not parked in a location that would cause an obstruction to traffic, such as within a lane on a road or at a railroad crossing. This makes it possible to avoid situations in which a parked vehicle for overnight stays obstructs evacuation or the transportation of relief supplies.

In step S412, the server device 10 sends a vehicle camping mode preparation instruction to prepare the vehicle 12 for overnight stays to transition from the normal operating mode to the overnight stay mode.

In step S414, the vehicle 12 acquires authentication information of the evacuee who intends to stay overnight in the vehicle in preparation for switching to the overnight stay mode. After receiving an instruction to prepare for the overnight stay mode, the control unit 33 causes the communication unit 31, the detection unit 37, or the imaging unit 38 to start acquiring authentication information. For example, the communication unit 31 receives authentication information from the communication terminal device of the evacuee by short-range wireless communication. The evacuee uses an application on the communication terminal device, such as a smartphone, to input a password or a personal identification number and send it to the vehicle 12. The control unit 33 stores the password or personal identification number in the memory unit 32 as authentication information. In addition, the detection unit 37 reads a fingerprint from the finger of the evacuee who touches the door knob or the like using a fingerprint sensor provided on the door knob or the like, and sends the read information to the control unit 33. The control unit 33 extracts the characteristics of the fingerprint and stores information indicating the characteristics in the memory unit 33 as authentication information. In addition, the imaging unit 38 captures the face of the evacuee who approaches within an arbitrarily set distance range using an external camera, and sends the captured image to the control unit 33. The control unit 33 extracts facial features and stores information indicating those features in the storage unit 32 as authentication information.

When executing step S414, the vehicle 12 may output information indicating that it is a vehicle for overnight camping, making it easier for the evacuees to recognize the presence of the vehicle 12. For example, the control unit 33 may cause the lights of the vehicle 12 to blink in an arbitrary pattern or project information indicating that it is a vehicle for overnight camping onto the windshield. Alternatively, the server device 10 may distribute information indicating the location of the vehicle 12 selected as a vehicle for overnight camping to the information communication terminal device of the evacuees.

In step S416, the vehicle 12 sends the authentication information to the server device 10.

In step S418, the server device 10 verifies the authentication information received from the vehicle 12. The control unit 23 compares the authentication information received from the vehicle 12 with authentication information associated with the vehicle information of the other vehicle. If the authentication information received from the vehicle 12 is associated with the vehicle information of the other vehicle, it indicates that the evacuee has already secured another vehicle for overnight stays in the vehicle. Therefore, in this case, the control unit 23 returns to step S412, for example, to keep the vehicle 12 in a preparation state after the overnight stay mode so that the vehicle 12 does not transition to the overnight stay mode for the evacuee. This ensures that other evacuees have the opportunity to use the vehicle for overnight stays in the vehicle. On the other hand, if the authentication information received from the vehicle 12 is not associated with the vehicle information of the other vehicle, the control unit 23 associates the authentication information with the vehicle information of the vehicle 12. As a result, the vehicle 12 is assigned to the evacuee as a vehicle for overnight stays in the vehicle. Then, in step S420, the server device 10 sends a vehicle camping mode transition instruction to transition the vehicle 12 to a vehicle for camping in the vehicle camping mode.

In step S422, the vehicle 12 transitions from the normal operation mode to the overnight stay mode. In the normal operation mode, the vehicle 12 operates the door locks, transmission, brakes, and engine in response to the user's operations. On the other hand, in the overnight stay mode, the vehicle 12 unlocks the doors if they are locked, and stops operations in response to driving operations. The control unit 33 sends an instruction to the ECU 39 to transition to the overnight stay mode. For example, the control unit 33 sends an instruction to the door ECU to unlock the doors. The control unit 33 also sends one or more of the following to the target ECUs: an instruction to the transmission ECU to stop releasing the parking range, an instruction to the brake ECU to stop releasing the parking brake, and an instruction to the engine ECU to stop starting the engine. Each of the ECUs 39 operates in response to the instruction, and the vehicle 12 transitions to the overnight stay mode.

When the vehicle 12 transitions to the overnight stay mode, the doors are unlocked, allowing evacuees to get into the vehicle and spend the night there. Even if operations for driving are performed, such as releasing the parking range, releasing the parking brake, and starting the engine, at least one of the actions corresponding to such operations is stopped, so the vehicle 12 cannot be moved. This makes it possible to prevent the vehicle 12 from being moved or taken away without the owner's knowledge.

The procedure in FIG. 5 is the procedure after the vehicle 12 has switched to overnight stay mode. The procedure in FIG. 5 is executed when an evacuee who will be overnight stay in the vehicle gets into the vehicle 12 and begins overnight stay in the vehicle.

In step S500, the vehicle 12 acquires authentication information for evacuees who are staying overnight in the vehicle.

In step S502, the vehicle 12 sends the authentication information to the server device 10.

In step S504, the server device 10 performs authentication by checking the authentication information received from the vehicle 12 against the authentication information associated with the vehicle 12. If the authentication is not successful, the server device 10 cancels the subsequent steps. On the other hand, if the authentication is successful, in step S506, the server device 10 sends an operation response instruction to the vehicle 12 to cause the vehicle 12 to respond to the operation by the evacuee.

In step S508, the vehicle 12 accepts the operation to lock or unlock the doors by the evacuees, and in step S510, locks or unlocks the doors in response to the operation. For example, the control unit 23 sends an instruction to the door ECU to permit acceptance of the operation and locking and unlocking the doors in response to the operation.

According to the procedure in Figure 5, evacuees who stay overnight in the vehicle 12 can lock the vehicle from inside the vehicle, and can lock and unlock the vehicle when they leave the vehicle. This makes it possible to ensure the safety of evacuees who stay overnight in the vehicle, as well as the safety of their belongings that are left behind in the vehicle when they leave the vehicle.

As described above, this embodiment makes it possible to improve convenience for evacuees and vehicle owners in the event of a disaster.
