The wireless communication I/F 31E is capable of performing Bluetooth Low Energy (BLE) (registered trademark) communication with the portable device 80, which is described below.

FIG. 7 is a block diagram illustrating an example of a functional configuration of the ECU 31. The ECU 31 includes, as a functional configuration, a seat control section 311, a driving assistance control section 312, a door lock control section 313, a lighting control section 314, a display control section 315, an audio control section 316, a setting control section 317, and a transmission/reception control section 318. These are implemented by the CPU 31A reading and executing a program stored in the ROM 31B.

The seat control section 311 controls at least one of the actuator 42 or the actuator 48 to change at least one of a sliding position or a reclining position of the driver's seat 36. For example, when a position control switch (not illustrated) provided at the driver's seat 36 is operated, the seat control section 311 controls the actuator 42 to change the reclining position of the driver's seat 36. Moreover, when the position control switch is operated, the seat control section 311 controls the actuator 48 to change the sliding position of the driver's seat 36.

The driving assistance control section 312 executes driving assistance control selected by the driving assistance switch 50 when the driving assistance switch 50 is operated. For example, when adaptive cruise control (ACC) is selected by the driving assistance switch 50, the driving assistance control section 312 controls the drive source and the brake device (neither of which are illustrated) of the first vehicle 30. This causes the first vehicle 30 to travel so as to maintain a following distance between the first vehicle 30 and a preceding vehicle (not illustrated) located ahead of the first vehicle 30 at a set distance.

For example, when the wireless communication I/F 31E receives a lock control signal from the portable device 80, the door lock control section 313 controls the actuators 54 to switch the door lock devices 53 from the unlocked state to the locked state. Moreover, when the wireless communication I/F 31E receives an unlock control signal from the portable device 80, the door lock control section 313 controls the actuators 54 to switch the door lock devices 53 from the locked state to the unlocked state.

The lighting control section 314 performs autonomous lighting control when the detection value of the light sensor 57 has reached or exceeded the predetermined first threshold value. Namely, the lighting control section 314 automatically turns on the headlights 56. Moreover, under the condition in which the start button 64 is off, when a time corresponding to the second threshold value has elapsed since the doors 52A and 52B were switched from the open state to the closed state, the lighting control section 314 turns off the interior light 58 that was in a lit state.

The display control section 315 controls the display 33. For example, when the navigation application is running, based on the navigation setting information, the display control section 315 changes the scale of the map displayed at the display 33, the display direction of the map, and the language and the unit representing the length (distance) of the map.

The audio control section 316 controls the audio device 60. For example, based on the audio setting information, the audio control section 316 changes the volume of the above-described speaker and conditions relating to BLE communication between the wireless earphone worn by the user UE and the wireless communication I/F 31E.

The setting control section 317 records the setting information for the first vehicle 30 in the storage 31D. For example, assume a case in which the sliding position and the reclining position of the driver's seat 36 are respectively at predetermined positions. In this state, when the user UE inputs a seat position determination instruction into the display 33 (touch panel), the setting control section 317 records the seat position setting information relating to the sliding position and the reclining position at this time in the storage 31D as setting information. Moreover, using the display 33 (touch panel), when the driving assistance setting information, the headlight setting information (the first threshold value), the navigation setting information, the audio setting information, the interior light setting information (the second threshold), and the door lock setting information of the boarding setting information, the travel setting information, and the deboarding setting information are input, the setting control section 317 records these pieces of information in the storage 31D.

When the setting information is recorded in the storage 31D, the seat control section 311, the driving assistance control section 312, the door lock control section 313, the lighting control section 314, the display control section 315, and the audio control section 316 perform control based on the setting information recorded in the storage 31D. For example, in a case in which the sliding position and the reclining position of the driver's seat 36 are recorded in the storage 31D as setting information, the seat control section 311 sets the sliding position and the reclining position of the driver's seat 36 to a position represented by the setting information. Moreover, in a case in which driving assistance setting information is recorded in the storage 31D, the driving assistance control section 312 executes driving assistance control based on this driving assistance setting information. Further, in a case in which information to execute automatic door lock control and automatic door unlock control is recorded in the storage 31D as door lock setting information, the door lock control section 313 executes automatic door lock control and automatic door unlock control.

Moreover, each time the setting information is updated, the setting control section 317 controls the wireless communication I/F 31E so as to wirelessly transmit, to the management server 20, the setting information recorded in the storage 31D. In a case in which the wireless communication I/F 21E receives the latest setting information from the first vehicle 30, the information management section 213 of the management server 20 creates (updates) the setting information list 25 illustrated in FIG. 8, and records this in the storage 21D. The setting information list 25 includes all of the setting information relating to the first vehicle 30. The setting information list 25 further includes vehicle ID information, which is ID information for the vehicle corresponding to the setting information, and member ID information, which is ID information for the member. The setting information list 25 includes information relating to priority. The setting information list 25 of the present exemplary embodiment indicates that the priority of the boarding setting information is “1”, the priority of the travel setting information is “2”, and the priority of the deboarding setting information is “3”. The smaller the number representing the priority, the higher the priority.

The transmission/reception control section 318 controls the wireless communication I/F 31E. The wireless communication I/F 31E, which is controlled by the transmission/reception control section 318, is capable of recording data received from an outside in the ROM 31B and the storage 31D, and of wirelessly transmitting the data recorded in the ROM 31B and the storage 31D to an outside.

The second vehicle 70 illustrated in FIG. 1 is one of many vehicles managed by the above-described administrator. The second vehicle 70 is a selected vehicle that is selected by the user UE from this vehicle group. The vehicle type of the second vehicle 70 is the same as the vehicle type of the first vehicle 30. In other words, the vehicle type code of the second vehicle 70 is the same as the vehicle type code of the first vehicle 30. Namely, the hardware configuration of the second vehicle 70 is the same as the hardware configuration of the first vehicle 30, and the same program (application) as that installed in the ECU 31 of the first vehicle 30 is installed in the ECU 71 of the second vehicle 70.

As illustrated in FIG. 9, the ECU 71 of the second vehicle 70 further includes, as a functional configuration, a seat control section 711, a driving assistance control section 712, a door lock control section 713, a lighting control section 714, a display control section 715, an audio control section 716, a setting control section 717, and a transmission/reception control section 718, which respectively correspond to the seat control section 311, the driving assistance control section 312, the door lock control section 313, the lighting control section 314, the display control section 315, the audio control section 316, the setting control section 317, and the transmission/reception control section 318. The ECU 71 further includes, as a functional configuration, a digital key acquisition section 719, a portable device digital key acquisition section 720, and a digital key authentication section 721.

The digital key acquisition section 719 acquires a digital key wirelessly transmitted by the management server 20 when the wireless communication I/F 71E receives this digital key.

The portable device digital key acquisition section 720 acquires a digital key (authentication data) from a portable device (for example, the portable device 80) via a Bluetooth Low Energy (BLE) (registered trademark) link established with the portable device.

The digital key authentication section 721 performs digital key authentication using the digital key acquired by the digital key acquisition section 719 and the digital key acquired by the portable device digital key acquisition section 720.

The user UE may inform the administrator in the above-described building of which vehicle is the selected vehicle. In this case, the administrator inputs information relating to the selected vehicle of the user UE into an operation terminal (not illustrated) connected to the management server 20. The information relating to the selected vehicle input into the operation terminal is transmitted from the operation terminal to the management server 20, and is recorded in the storage 21D. Alternatively, the user UE may input the information relating to the selected vehicle into the portable device 80 via the display (input section) 82. In this case, the portable device 80 wirelessly transmits the information relating to the selected vehicle input into the portable device 80 to the management server 20, and the management server 20 records the received information relating to the selected vehicle in the storage 21D. Moreover, the transmission/reception control section 212 of the management server 20 transmits the digital key to the portable device 80 and the second vehicle 70 which is the selected vehicle.

Further, although in the following explanation, the processing illustrated in the respective flowcharts of FIG. 12 to FIG. 16 is executed by a single processor (CPU), plural processors (CPUs) may execute the processing illustrated in the respective flowcharts of FIG. 12 to FIG. 16.

The CPU 21A of the management server 20 repeatedly executes the processing of the flowchart of FIG. 12 every time a predetermined period of time elapses.

At step S10, the CPU 21A determines whether or not setting information for the vehicle has been acquired. For example, in a case in which the first vehicle 30 wirelessly transmits the setting information recorded in the storage 31D to the management server 20, the CPU 21A determines YES at step S10, and proceeds to step S11.

At step S11, the CPU 21A creates (updates) the setting information list 25.

Next, at step S12, the CPU 21A determines whether or not the wireless communication I/F 21E has received a transmission request for the setting information list 25. The transmission request can be transmitted by the portable device 80. Note that a transmission request input into the above-described operation terminal may be transmitted from the operation terminal to the management server 20. The transmission request includes vehicle ID information and member ID information, which correspond to the setting information list 25 that is the transmission object, as well as information relating to the vehicle ID of the selected vehicle.

In a case in which the determination at step S12 is YES, the CPU 21A proceeds to step S13, and controls the wireless communication I/F 21E so as to transmit all of the setting information listed in the setting information list 25 to the second vehicle 70. At this time, the management server 20 transmits the respective setting information in an order based on the priority described above. Note that at this time, the management server 20 may transmit the respective setting information in an arbitrary order. Moreover, at step S13, the CPU 21A controls the wireless communication I/F 21E so as to wirelessly transmit the digital key to the second vehicle 70 and the portable device 80.

Next, at step S14, the CPU 21A determines whether or not the wireless communication I/F 21E has received a confirmation signal from the second vehicle 70. As described below, when receiving the setting information included in the setting information list 25, the second vehicle 70 wirelessly transmits a confirmation signal to the management server 20. On the other hand, in a case in which a failure has occurred in wireless communication between the management server 20 and the second vehicle 70, the CPU 21A determines NO at step S14.

In a case in which the determination at step S14 is NO, the CPU 21A proceeds to step S15 to wirelessly transmit the setting information list 25 to the portable device 80. At this time, the management server 20 transmits the respective setting information in an order based on the priority described above. Note that at this time, the management server 20 may transmit the respective setting information in an arbitrary order.

In a case in which the determination at step S12 is NO, in a case in which the determination at step S14 is YES or in a case in which the processing at step S15 has ended, the CPU 21A temporarily ends the processing of the flowchart of FIG. 12.

Next, explanation follows regarding processing performed by the CPU 71A of the ECU 71 of the second vehicle 70. The CPU 71A repeatedly executes the processing of the flowchart of FIG. 13 every time a predetermined period of time elapses.

At step S20, the CPU 71A determines whether or not the digital key has been received from the management server 20.

In a case in which the determination at step S20 is YES, the CPU 71A proceeds to step S21, records the acquired digital key in the storage 71D, and sets the value of a first key flag to “1”. Note that the initial value of the first key flag is “0”.

In a case in which the determination at step S20 is NO, or in a case in which the processing at step S21 has ended, the CPU 71A proceeds to step S22 to determine whether or not the respective setting information specified in the setting information list 25 has been received from the management server 20. In a case in which a failure has occurred in wireless communication between the management server 20 and the second vehicle 70, the CPU 71A makes a NO determination at step S22.

In a case in which the determination at step S22 is YES, the CPU 71A proceeds to step S23, and controls the wireless communication I/F 71E so as to transmit the confirmation signal to the management server 20. Moreover, the CPU 71A sets the value of a first information flag to “1”. Note that the initial value of the first information flag is “0”.

Next, the CPU 71A proceeds to step S24, and records the acquired setting information in the storage 71D. This enables the seat control section 711, the driving assistance control section 712, the door lock control section 713, the lighting control section 714, the display control section 715, and the audio control section 716 to perform control based on the setting information recorded in the storage 71D.

In a case in which the determination at step S22 is NO, or in a case in which the processing at step S24 has ended, the CPU 71A temporarily ends the processing of the flowchart of FIG. 13.

The CPU 71A repeatedly executes the processing of the flowchart of FIG. 14 every time a predetermined period of time elapses.

At step S30, the CPU 71A determines whether or not the digital key has been received from the portable device 80.

In a case in which the determination at step S30 is YES, the CPU 71A proceeds to step S31 to determine whether or not the value of the first key flag is “1”.

In a case in which the determination at step S31 is YES, the CPU 71A proceeds to step S32, and performs authentication of the digital key acquired from the portable device 80 using the digital key acquired from the management server 20.

In a case in which the digital key acquired from the portable device 80 is authenticated at step S32, the CPU 71A proceeds to step S33, and controls the actuator 54 to switch the door lock devices 53 that were in the locked state to the unlocked state.

Next, the CPU 71A proceeds to step S34 to determine whether or not the value of the first information flag is “0”.

In a case in which the determination at step S34 is YES, the CPU 71A proceeds to step S35 to determine whether or not the portable device 80 is transmitting the setting information to the second vehicle 70.

In a case in which the determination at step S35 is YES, the CPU 71A proceeds to step S36 to cause the wireless communication I/F 71E to receive the setting information. At this time, the portable device 80 sequentially transmits the respective setting information to the second vehicle 70 according to the priority specified in the setting information list 25 recorded in the portable device 80. Namely, the portable device 80 transmits the respective setting information to the second vehicle 70 in the order of the boarding setting information, the travel setting information, and the deboarding setting information. In this case, for example, when transmitting the boarding setting information, the wireless communication I/F 81E may transmit the door lock setting information after transmitting the seat position setting information. Further, the wireless communication I/F 81E may transmit the travel-related setting information prior to the entertainment related setting information. Moreover, the wireless communication I/F 81E may transmit the travel-related setting information in the order of the driving assistance setting information, the headlight setting information, the door lock setting information, and the navigation setting information. The wireless communication I/F 81E may transmit the deboarding setting information in the order of, for example, the interior light setting information and the door lock setting information.

The respective setting information received by the wireless communication I/F 71E is recorded in the storage 71D in the received order. This enables the seat control section 711, the driving assistance control section 712, the door lock control section 713, the lighting control section 714, the display control section 715, and the audio control section 716 to perform control based on the setting information recorded in the storage 71D. For example, in a case in which only the seat position setting information is recorded in the storage 71D, the seat control section 711 controls the actuator 42 and the actuator 48 based on the seat position setting information recorded in the storage 71D. On the other hand, at this time, the driving assistance control section 712, the door lock control section 713, the lighting control section 714, the display control section 715, and the audio control section 716 cannot execute control based on the setting information recorded in the storage 71D.

In a case in which the determination at step S30 to step S32, step S34 or step S35 is NO, or in a case in which the processing at step S36 has ended, the CPU 71A temporarily ends the processing of the flowchart of FIG. 14.

Next, explanation follows regarding processing performed by the CPU 81A of the portable device 80. The CPU 81A repeatedly executes the processing of the flowchart of FIG. 15 every time a predetermined period of time elapses.

At step S40, the CPU 81A determines whether or not the transmission request has been input via the display (touch panel) 82.

In a case in which the determination at step S40 is YES, the CPU 81A proceeds to step S41, and controls the wireless communication I/F 81E so as to transmit the transmission request to the management server 20.

In a case in which the determination at step S40 is NO, or in a case in which the processing at step S41 has ended, at step S42, the CPU 81A determines whether or not the digital key has been received from the management server 20.

In a case in which the determination at step S42 is YES, the CPU 81A proceeds to step S43, records the acquired digital key in the storage 81D, and sets the value of a second key flag to “1”. Note that the initial value of the second key flag is “0”.

In a case in which the determination at step S42 is NO, or in a case in which the processing of step S43 has ended, the CPU 81A proceeds to step S44 to determine whether or not the setting information list 25 has been received from the management server 20.

In a case in which the determination at step S44 is YES, the CPU 81A proceeds to step S45, and sets the value of a second information flag to “1”. Note that the initial value of the second information flag is “0”.

In a case in which the determination at step S44 is NO, or in a case in which the processing at step S45 has ended, the CPU 81A temporarily ends the processing of the flowchart of FIG. 15.

The CPU 81A repeatedly executes the processing of the flowchart of FIG. 16 every time a predetermined period of time elapses.

At step S50, the CPU 81A determines whether or not a BLE link has been established with the second vehicle 70 (the wireless communication I/F 71E). A BLE link is established when the distance between the portable device 80 and the second vehicle 70 is equal to or less than a predetermined distance.

In a case in which the determination at step S50 is YES, the CPU 81A proceeds to step S51 to determine whether or not the value of the second key flag is “1”.

In a case in which the determination at step S51 is YES, the CPU 81A proceeds to step S52, and controls the wireless communication I/F 81E so as to transmit the digital key to the second vehicle 70.

When the processing of step S52 has ended, the CPU 81A proceeds to step S53, and determines whether or not an instruction to change the content of the setting information recorded in the storage 81D has been input into the portable device 80 via the display 82.

In a case in which the determination at step S53 is YES, the CPU 81A proceeds to step S54 to update the content of the setting information recorded in the storage 81D. For example, in a case in which setting information relating to the sliding position of the driver's seat 36 is already recorded in the storage 81D, when new setting information relating to the sliding position is input via the display 82, the CPU 81A updates the setting information relating to the sliding position recorded in the storage 81D.

When the processing of step S54 has ended, the CPU 81A proceeds to step S55 to determine whether or not the value of the second information flag is “1”.

In a case in which the determination at step S55 is YES, the CPU 81A proceeds to step S56, and causes the wireless communication I/F 81E to transmit the setting information specified in the setting information list 25 to the second vehicle 70. At this time, the portable device 80 transmits the respective setting information to the second vehicle 70 in the manner described above based on the priority. Note that at this time, the wireless communication I/F 81E may simultaneously transmit data representing the boarding setting information and data representing the digital key to the second vehicle 70. For example, in a case in which the seat position setting information is transmitted prior to the door lock setting information, the wireless communication I/F 81E may use one packet to transmit data representing the seat position setting information and data representing the digital key to the second vehicle 70.

In a case in which the determination at step S50, step S51, step S53 or step S55 is NO, or in a case in which the processing of step S56 has ended, the CPU 81A temporarily ends the processing of the flowchart of FIG. 16.

As described above, in a case in which a failure has occurred in wireless communication between the management server 20 and the second vehicle 70, the portable device 80 of the present exemplary embodiment acquires setting information, which is information relating to user settings of the onboard devices of the first vehicle 30, from the management server 20, for example. Moreover, the portable device 80 transmits the setting information relating to the onboard devices of the first vehicle 30 to the second vehicle 70 by wireless communication with the second vehicle 70. Accordingly, even in a case in which a failure has occurred in wireless communication between the management server 20 holding the setting information and the second vehicle 70, the second vehicle 70 can receive the setting information.

Moreover, the second vehicle 70 receives the setting information from the portable device 80 only in a case in which the second vehicle 70 authenticates the digital key transmitted by the portable device 80. Accordingly, for example, the onboard devices of the second vehicle 70 are not controlled based on the setting information transmitted by a portable device owned by a person who is not a member of the system 10.

Furthermore, based on the priority specified in the setting information list 25, the portable device 80 sequentially transmits the respective setting information to the second vehicle 70. Namely, in the present exemplary embodiment, the setting information is transmitted to the second vehicle 70 in the order of the boarding setting information, the travel setting information, and the deboarding setting information. In this manner, the boarding setting information is first transmitted to the second vehicle 70. Accordingly, for example, before the second vehicle 70 completes receiving the travel setting information and the deboarding setting information, the sliding position and the reclining position of the driver's seat 36 of the second vehicle 70 can be changed based on the setting information relating to the sliding position and the reclining position of the driver's seat 36. Accordingly, regardless of whether or not the second vehicle 70 has completed receiving the travel setting information and the deboarding setting information, the sliding position and the reclining position of the driver's seat 36 can be set to a position that is preferable for the user UE when the user UE boards the second vehicle 70. Moreover, even in a case in which the second vehicle 70 is unable to receive the deboarding setting information due to a communication failure, for example, the display 33, the headlights 56, the audio device 60, the car navigation system, and the execution system of driving assistance control can be controlled based on the respective setting information during travel of the second vehicle 70.

Although the portable device, the setting information transmission method, and the non-transitory recording medium according to the exemplary embodiment have been explained above, appropriate design modifications to the portable device, the setting information transmission method, and the non-transitory recording medium can be made within a range that does not depart from the gist of the present disclosure.

For example, the setting information of the first vehicle 30 may be input into the above-described operation terminal, and the management server 20 may create (update) the setting information list 25 based on the setting information.

The portable device 80 may receive the setting information for the first vehicle 30 from the first vehicle 30 by wireless communication, and may wirelessly transmit the setting information acquired from the first vehicle 30 to the second vehicle 70. For example, when the setting information recorded in the storage 31D of the first vehicle 30 is updated, when the start button 64 of the first vehicle 30 is switched from an ON state to an OFF state, or when the door lock device 53 is switched from the unlocked state to the locked state, the first vehicle 30 may wirelessly transmit the setting information to the portable device 80. In this case, the portable device 80 may classify the setting information acquired from the first vehicle 30 based on the priority described above.

The first vehicle 30 and the second vehicle 70 may include a steering wheel 34 (a movable member), a position of which is adjustable in the front-rear direction (an axial direction of the steering wheel 34), and an actuator for adjusting a position of the steering wheel 34. In this case, the ECUs 31 and 71 may control the actuator based on setting information relating to the position of the steering wheel 34 in the front-rear direction. Note that the setting information relating to the position of the steering wheel 34 in the front-rear direction is boarding setting information.

The first vehicle 30 and the second vehicle 70 may include a rearview mirror (a movable member), a position of which adjustable, and an actuator for adjusting the position of the rearview mirror. In this case, the ECUs 31 and 71 may control the actuator based on setting information relating to the position of the rearview mirror. Note that the setting information relating to the position of the rearview mirror is boarding setting information.

The first vehicle 30 and the second vehicle 70 may include a side mirror (a movable member), an angle of which is adjustable with respect to a vehicle body, and an actuator for adjusting an angle of the side mirror. In this case, the ECUs 31 and 71 may control the actuator based on setting information relating to the angle of the side mirror. Note that the setting information relating to the angle of the side mirror is boarding setting information.

The second vehicle 70 and the portable device 80 may perform wireless communication using at least one of radio frequency (RF) band wireless communication, low frequency (LF) band wireless communication, near field communication (NFC) standard wireless communication or Wi-Fi.

The system 10 may be configured using a communication method conforming to a Car Connectivity Consortium (CCC) standard. Namely, the management server 20 may be an owner/friend device OEM server conforming to the CCC standard, and the portable device 80 may be an owner device or a friend device. In this case, the second vehicle 70 may authenticate the portable device 80 using BLE communication conforming to the CCC standard and a digital key. Moreover, the second vehicle 70 may execute the processing of step S33 when the second vehicle 70 has authenticated the portable device 80.

Alternatively, the portable device 80 may transmit the setting information to the second vehicle 70 when the second vehicle 70 authenticates the portable device 80 using wireless communication and the portable device 80 authenticates the second vehicle 70 using wireless communication.

In a case in which the second vehicle 70 authenticates the portable device 80, the portable device 80 may measure the distance to the second vehicle 70 using an ultra wideband (UWB) conforming to the CCC standard, and when the portable device 80 determines that the distance between the portable device 80 and the second vehicle 70 is equal to or less than a predetermined distance, the processing of step S33 and step S56 may be executed while using BLE communication. Alternatively, the processing of step S56 may be executed when the processing of step S33 is executed while using BLE communication.

The portable device 80 may be configured to switch between a state in which the setting information recorded in the storage 81D can be transmitted to the second vehicle 70 and a state in which the setting information cannot be transmitted. These two states are implemented when, for example, a predetermined instruction is input from the display 82 into the portable device 80.

In a case in which the vehicle type codes of the first vehicle 30 and the second vehicle 70 are different from each other, the portable device 80 may convert data representing the setting information for the first vehicle 30 into data usable by the vehicle group of the system 10, and then transmit this data to the vehicles of the system 10. In this case, the portable device 80 may acquire the vehicle codes of the first vehicle 30 and the vehicle group of the system 10 recorded in the storage 21D of the management server 20 by wireless communication. Moreover, the portable device 80 may acquire these vehicle codes by short-range wireless communication with the first vehicle 30 and the vehicle group of the system 10. Further, in a case in which the digital key for the first vehicle 30 recorded in the portable device 80 includes data representing the vehicle code of the first vehicle 30, and the digital key for the second vehicle 70 recorded in the portable device 80 includes data representing the vehicle code of the second vehicle 70, the portable device 80 may acquire the vehicle codes of the first vehicle 30 and the second vehicle 70 from these digital keys.

When the onboard devices of the second vehicle 70 become controllable based on the setting information due to the setting information being recorded in the storage 71D of the second vehicle 70, notification devices of the second vehicle 70 and the portable device 80 may inform the user UE thereof. The notification device of the second vehicle 70 is, for example, the display 33 and speakers of the audio device 60. The notification device of the portable device 80 is, for example, the display 82.

The first vehicle 30 need not be a vehicle owned by the user UE. For example, the first vehicle 30 may be a vehicle of a car sharing system. Similarly, the second vehicle 70 need not be a vehicle of the car sharing system. For example, the second vehicle 70 may be a vehicle owned by the user UE.

Note that the processing executed by each CPU reading and executing software (a program) in the above-described exemplary embodiment may be executed by various types of processor other than a CPU. Such processors include programmable logic devices (PLD) that allow circuit configuration to be modified post-manufacture, such as a field-programmable gate array (FPGA), and dedicated electric circuits, these being processors including a circuit configuration custom-designed to execute specific processing, such as an application specific integrated circuit (ASIC). Further, the respective processing may be executed by any one of these various types of processor, or by a combination of two or more of the same type or different types of processor. The hardware structure of these various types of processors is an electric circuit combining circuit elements such as semiconductor elements.
