DETAILED DESCRIPTION OF THE INVENTION

[0012] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0013] (First embodiment) 1 shows an example of the configuration of a vehicle control system 1 according to a first embodiment of the present invention. The vehicle control system 1 includes a vehicle control device 2 and a smartphone 3.

[0014] The vehicle control device 2 is provided in the vehicle. The smartphone 3 is a device having a battery, and performs wireless communication with the vehicle control device 2. The smartphone 3 also has a digital key and supports wireless power supply such as Qi.

[0015] 2 shows an example of the configuration of the vehicle control device 2. The vehicle control device 2 includes a vehicle control unit 20, a communication unit 21, a power supply unit 22, a battery 23, and a storage unit 24.

[0016] The vehicle control unit 20 controls the entire vehicle control device 2. The vehicle control unit 20 has a communication control unit 200, a digital key authentication unit 201, a door control unit 202, an engine control unit 203, a wireless power supply authentication unit 204, and a power supply control unit 205.

[0017] The communication control unit 200 controls wireless communication performed by the communication unit 21 with the smartphone 3. The digital key authentication unit 201 performs authentication before digital key-related controls, such as unlocking and locking doors and starting and stopping the engine, are performed. The door control unit 202 controls unlocking and locking doors. The engine control unit 203 controls starting and stopping the engine. The wireless power supply authentication unit 204 determines whether the smartphone 3 is compatible with wireless power supply by performing wireless power supply authentication (Qi authentication). The power supply control unit 205 causes the power supply unit 22 to perform wireless power supply.

[0018] The vehicle control unit 20 may be realized by a processor such as a CPU (Central Processing Unit) executing a program recorded on a computer-readable recording medium. The vehicle control unit 20 may be realized by hardware (circuitry) such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field-Programmable Gate Array). The vehicle control unit 20 may be realized by a combination of software and hardware.

[0019] The computer-readable recording medium may be a portable medium such as a flexible disk, a magneto-optical disk, a ROM, or a CD-ROM, or a storage unit such as a hard disk built into a computer system. The above-mentioned program may be a differential file (differential program). The functions of the vehicle control unit 20 may be realized by combining a program already stored in the computer with the differential program.

[0020] The communication unit 21 performs wireless communication with the smartphone 3. The power supply unit 22 has a power supply pocket in which the smartphone 3 is placed. When the smartphone 3 is placed in the power supply pocket, the power supply unit 22 transfers power from the battery 23 to the smartphone 3, charging the smartphone 3. The battery 23 is a rechargeable secondary battery.

[0021] The storage unit 24 is a non-volatile memory such as an erasable programmable read-only memory (EPROM), an electrically programmable read-only memory (EEPROM), or a flash memory. The storage unit 24 stores information about the digital key possessed by the smartphone 3.

[0022] The storage unit 24 may be configured as a tamper-resistant secure element. The digital key authentication unit 201 and the wireless power supply authentication unit 204 may each be configured as an application, and these applications may run on a single secure element. Alternatively, the storage unit 24 may be configured as two secure elements, and the digital key authentication unit 201 and the wireless power supply authentication unit 204 may run on different secure elements.

[0023] 3 shows an example of the configuration of the smartphone 3. The smartphone 3 includes a smartphone control unit 30, a communication unit 31, a battery 32, a display unit 33, and a storage unit .

[0024] The smartphone control unit 30 controls the entire smartphone 3. The smartphone control unit 30 includes a communication control unit 300, a digital key authentication unit 301, a wireless power supply authentication unit 302, a battery control unit 303, and a display control unit 304.

[0025] The communication control unit 300 controls wireless communication executed by the communication unit 31 with the vehicle control device 2. The digital key authentication unit 301 executes authentication before control related to the digital key is executed. The wireless power supply authentication unit 302 executes wireless power supply authentication. The battery control unit 303 controls the battery 32. The display control unit 304 controls the display unit 33.

[0026] The smartphone control unit 30 may be realized by a processor executing a program recorded on a computer-readable recording medium. The smartphone control unit 30 may be realized by hardware (circuit) such as an ASIC or FPGA. The smartphone control unit 30 may be realized by a combination of software and hardware. The functions of the smartphone control unit 30 may be realized by a combination of a program already recorded on a computer and a differential program.

[0027] The communication unit 31 performs wireless communication with the vehicle control device 2. The battery 32 is a rechargeable secondary battery. The display unit 33 is a display device such as an LCD display, and displays the status of the smartphone 3, etc. The memory unit 34 is a non-volatile memory such as an EPROM, EEPROM, or flash memory. The memory unit 34 stores information about the digital key.

[0028] The storage unit 24 of the vehicle control device 2 stores in advance information about the device public key, which is the digital key of the smartphone 3, and an ID for identifying the device public key. The storage unit 34 of the smartphone 3 stores in advance information about the public key of the vehicle control device 2 and an ID for identifying the public key of the vehicle control device 2. The ID stored in the storage unit 24 and the ID stored in the storage unit 34 are the same.

[0029] Fig. 4 shows an example of processing executed by the vehicle control device 2. The processing executed by the vehicle control device 2 will be described with reference to Fig. 4. For example, when a user holds the smartphone 3 over the door of the vehicle, the processing shown in Fig. 4 is executed.

[0030] (Step S100) The digital key authentication unit 201 performs authentication to unlock the vehicle doors. Details of step S100 will be described later.

[0031] (Step S101) If the authentication is successful, the door control unit 202 unlocks the door. If the authentication is not successful, the door control unit 202 does not unlock the door, and the process shown in FIG. 4 ends.

[0032] (Step S102) After the door is unlocked, the communication control unit 200 generates a message display instruction to instruct the smartphone 3 to display a message prompting charging, and outputs the message display instruction to the communication unit 21. The communication unit 21 transmits the message display instruction to the smartphone 3.

[0033] As will be described later, the smartphone 3 receives the message display instruction and displays a message prompting charging on the display unit 33. The user of the smartphone 3 follows the message and places the smartphone 3 in the power supply pocket.

[0034] (Step S103) After the smartphone 3 is set in the power supply pocket, the wireless power supply authentication unit 204 performs wireless power supply authentication. Details of step S103 will be described later.

[0035] (Step S104) If the wireless power supply authentication is successful, the power supply control unit 205 causes the power supply unit 22 to start wireless power supply. The power supply unit 22 starts wireless power supply and charges the smartphone 3. If the wireless power supply authentication is unsuccessful, wireless power supply is not performed, and the processing shown in FIG. 4 ends.

[0036] (Step S105) After wireless power supply is started, the digital key authentication unit 301 activates (validates) the digital key.

[0037] (Step S106) After the digital key is activated, the digital key authentication unit 201 performs authentication to start the vehicle engine. In step S106, the same process as in step S100 is performed.

[0038] (Step S107) If the authentication is successful, the engine control unit 203 starts the engine. If the authentication is unsuccessful, the engine control unit 203 does not start the engine.

[0039] Fig. 5 shows an example of processing executed by the smartphone 3. The processing executed by the smartphone 3 will be described with reference to Fig. 5. For example, when a user holds the smartphone 3 over a vehicle door, the processing shown in Fig. 5 is executed.

[0040] (Step S200) The digital key authentication unit 301 performs authentication to unlock the vehicle doors. Details of step S200 will be described later.

[0041] (Step S201) If the authentication is successful, the communication unit 31 receives a message display instruction from the vehicle control device 2 and outputs the message display instruction to the smartphone control unit 30. The display control unit 304 displays a message on the display unit 33 urging the user to charge the smartphone 3. If the authentication is not successful, the processing shown in FIG. 5 ends.

[0042] (Step S202) After checking the message displayed in step S201, the user places the smartphone 3 in the power supply pocket. After the smartphone 3 is placed in the power supply pocket, the wireless power supply authentication unit 302 performs wireless power supply authentication. Details of step S202 will be described later.

[0043] (Step S203) If the wireless power supply authentication is successful, the digital key authentication unit 301 executes authentication to start the vehicle engine. In step S203, the same processing as in step S200 is executed.

[0044] After wireless power supply authentication is performed, the power supply control unit 205 may repeatedly check whether the smartphone 3 is set in the power supply pocket. If the smartphone 3 is removed from the power supply pocket, the display control unit 304 may cause the display unit 33 to display again a message urging the user to charge the smartphone 3.

[0045] Fig. 6 shows an example of processing executed by the vehicle control device 2 and the smartphone 3 in steps S100 and S106 shown in Fig. 4 and steps S200 and S203 shown in Fig. 5. The processing executed by the vehicle control device 2 and the smartphone 3 will be described with reference to Fig. 6.

[0046] (Step S300) The communication control unit 200 of the vehicle control device 2 generates AUTHENTICATE including the vehicle temporary public key and the vehicle ID, and outputs AUTHENTICATE to the communication unit 21. The communication unit 21 transmits AUTHENTICATE to the smartphone 3. The communication unit 31 of the smartphone 3 receives AUTHENTICATE and outputs AUTHENTICATE to the smartphone control unit 30.

[0047] (Step S301) The digital key authentication unit 301 generates a response including the device temporary public key of the smartphone 3 and outputs the response to the communication unit 31. The communication unit 31 transmits the response to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the response and outputs the response to the vehicle control unit 20.

[0048] (Step S302) The digital key authentication unit 201 generates signature data by encrypting the vehicle ID with the vehicle temporary private key. The digital key authentication unit 201 generates AUTHENTICATE including the signature data and outputs AUTHENTICATE to the communication unit 21. The communication unit 21 transmits AUTHENTICATE to the smartphone 3. The communication unit 31 of the smartphone 3 receives AUTHENTICATE and outputs AUTHENTICATE to the smartphone control unit 30.

[0049] (Step S303) The digital key authentication unit 301 decrypts the signature data included in the AUTHENTICATE received in step S302 using the vehicle temporary public key included in the AUTHENTICATE received in step S300. The digital key authentication unit 301 verifies the signature data by comparing the vehicle ID obtained by decrypting the signature data with the vehicle ID included in the AUTHENTICATE received in step S300.

[0050] (Step S304) If the two vehicle IDs are the same, authentication is successful. The digital key authentication unit 301 generates a response including the ID stored in the memory unit 34 and outputs the response to the communication unit 31. The communication unit 31 transmits the response to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the response and outputs the response to the vehicle control unit 20. If the two IDs are different, authentication fails.

[0051] (Step S305) The digital key authentication unit 201 identifies the same ID as the ID included in the response received in step S304 in the storage unit 24. The digital key authentication unit 201 identifies the device public key associated with the identified ID.

[0052] In step S101, the door control unit 202 of the vehicle control device 2 unlocks the door by using the device public key. In step S107, the engine control unit 203 of the vehicle control device 2 starts the engine by using the device public key.

[0053] Fig. 7 shows an example of the processing executed by the vehicle control device 2 and the smartphone 3 in step S103 shown in Fig. 4 and step S202 shown in Fig. 5. The processing executed by the vehicle control device 2 and the smartphone 3 will be described with reference to Fig. 7.

[0054] (Step S400) The wireless power supply authentication unit 204 of the vehicle control device 2 generates a GET CERTIFICATE command and outputs the GET CERTIFICATE command to the communication unit 21. The communication unit 21 transmits the GET CERTIFICATE command to the smartphone 3. The communication unit 31 of the smartphone 3 receives the GET CERTIFICATE command and outputs the GET CERTIFICATE command to the smartphone control unit 30.

[0055] (Step S401) The wireless power supply authentication unit 302 generates a response including the certificate and outputs the response to the communication unit 31. The communication unit 31 transmits the response to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the response and outputs the response to the vehicle control unit 20.

[0056] (Step S402) The wireless power supply authentication unit 204 generates a CHALLENGE command including a random number and outputs the CHALLENGE command to the communication unit 21. The communication unit 21 transmits the CHALLENGE command to the smartphone 3. The communication unit 31 of the smartphone 3 receives the CHALLENGE command and outputs the CHALLENGE command to the smartphone control unit 30.

[0057] (Step S403) The wireless power supply authentication unit 302 generates signature data by using the certificate included in the response received in step S401 and the random number included in the CHALLENGE command received in step S402. The signature data is encrypted with the private key of the smartphone 3.

[0058] (Step S404) The wireless power supply authentication unit 302 generates a response including the signature data and outputs the response to the communication unit 31. The communication unit 31 transmits the response to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the response and outputs the response to the vehicle control unit 20.

[0059] (Step S405) The wireless power supply authentication unit 204 decrypts the signature data using the public key of the smartphone 3. The wireless power supply authentication unit 204 generates signature data by using the certificate included in the response generated in step S401 and the random number included in the CHALLENGE command generated in step S402. The wireless power supply authentication unit 204 verifies the signature data by comparing the generated signature data with the signature data received from the smartphone 3.

[0060] If the two signature data are the same, the wireless power authentication is successful. If the two signature data are different, the wireless power authentication is unsuccessful.

[0061] In the wireless power supply authentication, the wireless power supply authentication unit 204 determines whether the smartphone 3 supports wireless power supply. If the smartphone 3 supports wireless power supply, the vehicle control device 2 performs wireless power supply to the smartphone 3, thereby preventing the remaining charge of the battery 32 of the smartphone 3 from running low while the vehicle is traveling.

[0062] As described above, the wireless power supply authentication unit 204 (determination unit) of the vehicle control device 2 determines whether the smartphone 3 supports wireless power supply. Specifically, the wireless power supply authentication unit 204 determines whether the smartphone 3 supports wireless power supply by performing wireless power supply authentication. If it is determined that the smartphone 3 supports wireless power supply, the power supply unit 22 of the vehicle control device 2 starts wireless power supply to the smartphone 3. The communication unit 21 (first communication unit) of the vehicle control device 2 receives digital key information (ID) for starting the vehicle engine from the smartphone 3. After wireless power supply is started, the engine control unit 203 (control unit) starts the engine by using the digital key (device public key) indicated by the digital key information (ID).

[0063] The battery 32 of the smartphone 3 is charged by wireless power supply. The memory unit 34 of the smartphone 3 stores the digital key information (ID). The communication unit 31 (second communication unit) of the smartphone 3 transmits the digital key information to the vehicle control device 2.

[0064] With the above configuration, the vehicle control system 1 can prevent the remaining charge of the battery 32 of the smartphone 3 from running low while the vehicle is traveling.

[0065] (First Modification of the First Embodiment) A first modification of the first embodiment of the present invention will be described. In the first modification of the first embodiment, the vehicle control device 2 performs wireless power supply to the smartphone 3 when the remaining charge of the battery 32 of the smartphone 3 is low.

[0066] Fig. 8 shows an example of processing executed by the vehicle control device 2. The processing executed by the vehicle control device 2 will be described with reference to Fig. 8. Processing that differs from the processing shown in Fig. 4 will be described, and a description of processing that is the same as the processing shown in Fig. 4 will be omitted.

[0067] (Step S110) After the vehicle doors are unlocked in step S101, the wireless power supply authentication unit 204 generates a remaining charge check instruction to instruct the smartphone 3 to check the remaining charge of the battery 32 of the smartphone 3, and outputs the remaining charge check instruction to the communication unit 21. The communication unit 21 transmits the remaining charge check instruction to the smartphone 3.

[0068] The communication unit 31 of the smartphone 3 receives the remaining charge check instruction and outputs the remaining charge check instruction to the smartphone control unit 30. The battery control unit 303 checks the remaining charge of the battery 32 and generates remaining charge information indicating the remaining charge. For example, the remaining charge information indicates the ratio of the remaining charge to the total capacity of the battery 32. The battery control unit 303 outputs the remaining charge information to the communication unit 31. The communication unit 31 transmits the remaining charge information to the vehicle control device 2.

[0069] (Step S111) The communication unit 21 of the vehicle control device 2 receives the remaining amount information and outputs the remaining amount information to the vehicle control unit 20.

[0070] (Step S112) The wireless power supply authentication unit 204 determines whether the remaining amount indicated by the remaining amount information is equal to or greater than a predetermined amount (for example, 20%). The predetermined amount is pre-stored in the storage unit 24. The predetermined amount is not limited to 20%. If the remaining amount is equal to or greater than the predetermined amount, step S105 is executed. If the remaining amount is less than the predetermined amount, step S102 is executed.

[0071] As described above, the communication unit 31 of the smartphone 3 transmits remaining charge information indicating the remaining charge of the battery 32 of the smartphone 3 to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the remaining charge information from the smartphone 3. If the remaining charge indicated by the remaining charge information is less than a predetermined amount, the wireless power supply authentication unit 204 of the vehicle control device 2 determines whether the smartphone 3 supports wireless power supply. If it is determined that the smartphone 3 supports wireless power supply, the power supply unit 22 of the vehicle control device 2 starts wireless power supply to the smartphone 3. This allows the vehicle control system 1 to reliably prevent the remaining charge of the battery 32 of the smartphone 3 from running low while the vehicle is traveling.

[0072] (Second Modification of the First Embodiment) A second modified example of the first embodiment of the present invention will be described. In the second modified example of the first embodiment, the vehicle control device 2 instructs the smartphone 3 to check the remaining charge of the battery 32. If the remaining charge of the battery 32 is low, the smartphone 3 instructs the vehicle control device 2 to perform wireless power supply authentication.

[0073] Fig. 9 shows an example of processing executed by the vehicle control device 2. The processing executed by the vehicle control device 2 will be described with reference to Fig. 9. Processing that differs from the processing shown in Fig. 8 will be described, and a description of processing that is the same as the processing shown in Fig. 8 will be omitted.

[0074] In step S110, the vehicle control device 2 transmits a remaining charge check instruction to the smartphone 3. As will be described later, upon receiving the remaining charge check instruction, the smartphone 3 checks the remaining charge of the battery 32. If the remaining charge of the battery 32 is low, the smartphone 3 transmits a wireless power supply authentication instruction to the vehicle control device 2 to instruct the vehicle control device 2 to perform wireless power supply authentication.

[0075] (Step S120) After the remaining power check instruction is sent to the smartphone 3 in step S110, the wireless power supply authentication unit 204 determines whether or not a wireless power supply authentication instruction has been received. If a wireless power supply authentication instruction has been received, step S103 is executed. If a wireless power supply authentication instruction has not been received, step S105 is executed.

[0076] Fig. 10 shows an example of processing executed by the smartphone 3. The processing executed by the smartphone 3 will be described with reference to Fig. 10. Processing that differs from the processing shown in Fig. 5 will be described, and a description of processing that is the same as the processing shown in Fig. 5 will be omitted.

[0077] (Step S220) If the authentication in step S200 is successful, the communication unit 31 receives a remaining amount check instruction from the vehicle control device 2 and outputs the remaining amount check instruction to the smartphone control unit 30.

[0078] (Step S221) After receiving the remaining charge check instruction, the battery control unit 303 checks the remaining charge of the battery 32 and generates remaining charge information indicating the remaining charge.

[0079] (Step S222) The wireless power supply authentication unit 302 determines whether the remaining amount indicated by the remaining amount information is equal to or greater than a predetermined amount (for example, 20%). The predetermined amount is pre-stored in the storage unit 34. The predetermined amount is not limited to 20%. If the remaining amount is equal to or greater than the predetermined amount, step S203 is executed. If the remaining amount is less than the predetermined amount, step S223 is executed.

[0080] (Step S223) If the remaining amount is less than the predetermined amount, the wireless power supply authentication unit 302 generates a wireless power supply authentication instruction and outputs the wireless power supply authentication instruction to the communication unit 31. The communication unit 31 transmits the wireless power supply authentication instruction to the vehicle control device 2. After the wireless power supply authentication instruction is transmitted, step S201 is executed.

[0081] As described above, when the remaining charge of the battery 32 is less than a predetermined amount, the communication unit 31 of the smartphone 3 transmits a wireless power supply authentication instruction (instruction information) to the vehicle control device 2 to instruct the smartphone 3 to determine whether or not the smartphone 3 is compatible with wireless power supply. The communication unit 21 of the vehicle control device 2 receives the wireless power supply authentication instruction from the smartphone 3. When the wireless power supply authentication instruction is received, the wireless power supply authentication unit 204 of the vehicle control device 2 determines whether or not the smartphone 3 is compatible with wireless power supply. When it is determined that the smartphone 3 is compatible with wireless power supply, the power supply unit 22 of the vehicle control device 2 starts wireless power supply to the smartphone 3. This allows the vehicle control system 1 to reliably prevent the remaining charge of the battery 32 of the smartphone 3 from running low while the vehicle is traveling.

[0082] (Third Modification of the First Embodiment) A third modification of the first embodiment of the present invention will be described. In the third modification of the first embodiment, the vehicle control device 2 performs authentication based on the driver's license information and vehicle inspection certificate information of the user of the smartphone 3 in addition to wireless power supply authentication.

[0083] The memory unit 34 of the smartphone 3 stores driver's license information in advance. The driver's license information includes vehicle model information indicating the vehicle model, expiration information indicating the driver's license renewal expiration date, and user name information. The memory unit 24 of the vehicle control device 2 stores vehicle inspection certificate information in advance. The vehicle inspection certificate information includes vehicle model information, expiration information, and owner information indicating the owner of the vehicle.

[0084] Fig. 11 shows an example of processing executed by the vehicle control device 2. The processing executed by the vehicle control device 2 will be described with reference to Fig. 11. Processing that differs from the processing shown in Fig. 4 will be described, and a description of processing that is the same as the processing shown in Fig. 4 will be omitted.

[0085] In step S102, a message display instruction is sent to the smartphone 3. The smartphone 3 receives the message display instruction and displays a message on the display unit 33 prompting the user to charge the smartphone 3. The smartphone 3 also sends the driver's license information stored in the memory unit 34 to the vehicle control device 2.

[0086] (Step S130) After the message display instruction is sent to the smartphone 3 in step S102, the communication unit 21 receives the driver's license information from the smartphone 3 and outputs the driver's license information to the vehicle control unit 20. The wireless power supply authentication unit 204 verifies the legitimacy of the user of the smartphone 3 by using the driver's license information and the vehicle inspection certificate information stored in the memory unit 24. In other words, the wireless power supply authentication unit 204 determines whether the user of the smartphone 3 is a legitimate driver.

[0087] The wireless power supply authentication unit 204 verifies that predetermined conditions are met for each of two or more items. For example, the wireless power supply authentication unit 204 verifies that the vehicle model information included in the driver's license information matches the vehicle model information included in the vehicle inspection certificate information. The wireless power supply authentication unit 204 verifies that the renewal period for the driver's license information has not expired. The wireless power supply authentication unit 204 verifies that the vehicle inspection certificate has not expired. The wireless power supply authentication unit 204 verifies that the name information included in the driver's license information matches the owner information included in the vehicle inspection certificate information. Items for verifying the legitimacy of the user of the smartphone 3 are not limited to these examples.

[0088] If the predetermined conditions are met for all of the two or more items, the wireless power supply authentication unit 204 determines that the user of the smartphone 3 is a legitimate driver. If the predetermined conditions are not met for one or more of the two or more items, the wireless power supply authentication unit 204 determines that the user of the smartphone 3 is not a legitimate driver.

[0089] If the user of the smartphone 3 is a legitimate driver, step S103 is executed. If the user of the smartphone 3 is not a legitimate driver, the process shown in FIG. 11 ends.

[0090] As described above, the memory unit 24 of the vehicle control device 2 stores vehicle inspection certificate information. The memory unit 34 of the smartphone 3 stores driver's license information. The communication unit 31 of the smartphone 3 transmits the driver's license information to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the driver's license information from the smartphone 3. The wireless power supply authentication unit 204 of the vehicle control device 2 determines whether the user of the smartphone 3 is a legitimate driver by using the vehicle inspection certificate information and the driver's license information. If it is determined that the smartphone 3 is compatible with wireless power supply and that the user of the smartphone 3 is a legitimate driver, the power supply unit 22 starts wireless power supply to the smartphone 3. This allows the vehicle control system 1 to prevent the remaining charge of the battery 32 of the smartphone 3 from running low while the vehicle is traveling, and to prevent anyone other than the legitimate driver from driving the smartphone 3.

[0091] (Second embodiment) A second embodiment of the present invention will be described. A vehicle control system 1 according to the second embodiment includes a smartphone 3 and a vehicle control device 2a shown in FIG. 12. FIG. 12 shows the configuration of the vehicle control device 2a. Configurations that differ from the configuration shown in FIG. 2 will be described, and descriptions of configurations that are the same as the configuration shown in FIG. 2 will be omitted.

[0092] The vehicle control device 2a includes a vehicle control unit 20a, a communication unit 21, a power supply unit 22, a battery 23, a memory unit 24, and a position measurement unit 25. The communication unit 21 receives remaining charge information indicating the remaining charge of the battery 32 of the smartphone 3 from the smartphone 3. The position measurement unit 25 includes, for example, a GPS (Global Positioning System) receiver and measures the current position of the vehicle. For example, the position measurement unit 25 measures the latitude, longitude, and altitude of the current position.

[0093] The storage unit 24 stores map information in advance. The map information includes, for example, location information including the latitude, longitude, and altitude of multiple locations on a map. For example, a car navigation system is provided in the vehicle, and the car navigation system uses the map information to provide route guidance to a destination.

[0094] The memory unit 24 also stores in advance an estimated value (estimated consumption amount) of the consumption amount of the battery 32 of the smartphone 3 according to the traveling distance of the vehicle. The vehicle control device 2a periodically communicates with the smartphone 3 to confirm that the smartphone 3 is present in the vehicle while the vehicle is traveling. Therefore, the smartphone 3 consumes power from the battery 32 while the vehicle is traveling. The number of times this communication is performed is proportional to the traveling distance of the vehicle. For example, the consumption amount of the battery 32 according to the traveling distance of the vehicle is measured multiple times in advance, and an estimated value is calculated from the measured value. The memory unit 24 may store the estimated consumption amount for each traveling distance of the vehicle. Alternatively, the memory unit 24 may store a calculation formula for calculating the estimated consumption amount from the traveling distance of the vehicle.

[0095] 2 is replaced with a vehicle control unit 20a. The vehicle control unit 20a includes a communication control unit 200, a digital key authentication unit 201, a door control unit 202, an engine control unit 203, a wireless power supply authentication unit 204, a power supply control unit 205, a distance calculation unit 206, and a remaining power calculation unit 207.

[0096] The distance calculation unit 206 calculates the planned driving distance of the vehicle from the current position (starting point) to the destination based on map information. The remaining amount calculation unit 207 acquires from the storage unit 24 the estimated power consumption of the battery 32 according to the distance calculated by the distance calculation unit 206 and the corresponding driving distance. The remaining amount calculation unit 207 calculates the estimated remaining amount of the battery 32 when the vehicle arrives at the destination by subtracting the estimated power consumption from the remaining amount indicated by the remaining amount information received by the communication unit 21. If the estimated remaining amount is low, the wireless power supply authentication unit 204 performs wireless power supply authentication.

[0097] Fig. 13 shows an example of processing executed by the vehicle control device 2a. The processing executed by the vehicle control device 2a will be described with reference to Fig. 13. Processing that differs from the processing shown in Fig. 8 will be described, and a description of processing that is the same as the processing shown in Fig. 8 will be omitted.

[0098] (Step S140) After the remaining charge check instruction is sent to the smartphone 3 in step S110, the position measurement unit 25 measures the current position of the vehicle and outputs current position information indicating the current position to the vehicle control unit 20a. The distance calculation unit 206 acquires the current position information.

[0099] (Step S141) After the current position information is acquired, the distance calculation unit 206 acquires destination information. For example, the distance calculation unit 206 acquires destination information from a car navigation system.

[0100] (Step S142) The distance calculation unit 206 acquires information on a point corresponding to the destination from map information, and calculates the distance from the current position to the destination (planned driving distance).

[0101] (Step S143) The remaining charge calculation unit 207 acquires from the storage unit 24 an estimated power consumption amount according to the travel distance corresponding to the distance calculated in step S142. The remaining charge indicated by the remaining charge information received by the communication unit 21 indicates the current remaining charge of the battery 32. The remaining charge calculation unit 207 subtracts the estimated power consumption amount from the current remaining charge of the battery 32 to calculate the estimated remaining charge of the battery 32 when the vehicle arrives at the destination.

[0102] (Step S144) The wireless power supply authentication unit 204 determines whether the estimated remaining amount calculated in step S143 is equal to or greater than a predetermined amount (for example, 5%). The predetermined amount is pre-stored in the storage unit 24. The predetermined amount is not limited to 5%. If the estimated remaining amount is equal to or greater than the predetermined amount, step S105 is executed. If the estimated remaining amount is less than the predetermined amount, step S102 is executed.

[0103] As described above, the memory unit 24 of the vehicle control device 2a stores the estimated power consumption of the battery 32 according to the vehicle's travel distance. The position measurement unit 25 of the vehicle control device 2a measures the vehicle's current position. The distance calculation unit 206 of the vehicle control device 2a calculates the distance from the current position to the destination based on map information. The communication unit 21 of the vehicle control device 2a receives remaining power information indicating the remaining power of the battery 32 from the smartphone 3. The remaining power calculation unit 207 of the vehicle control device 2a acquires from the memory unit 24 an estimated power consumption according to the travel distance corresponding to the calculated distance, and calculates the estimated remaining power of the battery 32 by subtracting the acquired estimated power consumption from the remaining power indicated by the remaining power information. If the estimated remaining power is less than a predetermined amount, the wireless power supply authentication unit 204 of the vehicle control device 2a determines whether the smartphone 3 is compatible with wireless power supply. If it is determined that the smartphone 3 is compatible with wireless power supply, the power supply unit 22 of the vehicle control device 2a starts wireless power supply to the smartphone 3. This allows the vehicle control system 1 to prevent the remaining charge of the battery 32 of the smartphone 3 from running low while the vehicle is traveling.

[0104] (Third embodiment) A third embodiment of the present invention will be described. A vehicle control system 1 according to the third embodiment includes a vehicle control device 2 and a smartphone 3a shown in FIG. 14. FIG. 14 shows the configuration of the smartphone 3a. Configurations that differ from the configuration shown in FIG. 3 will be described, and descriptions of configurations that are the same as the configuration shown in FIG. 3 will be omitted.

[0105] The smartphone 3a has a smartphone control unit 30a, a communication unit 31, a battery 32, a display unit 33, a memory unit 34, and a position measurement unit 35. The position measurement unit 35 has, for example, a GPS receiver and measures the current position of the smartphone 3a. When the smartphone 3a is held up to the door of the vehicle, the position measurement unit 35 measures the current position of the smartphone 3a. The current position of the smartphone 3a is the same as the current position of the vehicle.

[0106] The storage unit 34 stores map information in advance, and also stores an estimated value (estimated consumption amount) of the power consumption of the battery 32 according to the travel distance of the vehicle in advance.

[0107] The smartphone control unit 30a includes a communication control unit 300, a digital key authentication unit 301, a wireless power supply authentication unit 302, a battery control unit 303, a display control unit 304, a distance calculation unit 305, and a remaining battery calculation unit 306.

[0108] The distance calculation unit 305 calculates the distance from the current position (starting point) of the smartphone 3a to the destination based on map information. The remaining charge calculation unit 306 acquires from the storage unit 34 an estimated power consumption of the battery 32 according to the distance calculated by the distance calculation unit 305 and the corresponding travel distance. The remaining charge calculation unit 306 calculates the estimated remaining charge of the battery 32 when the vehicle arrives at the destination by subtracting the estimated power consumption from the current remaining charge of the battery 32. The communication unit 31 transmits estimated remaining charge information indicating the estimated remaining charge to the vehicle control device 2.

[0109] Fig. 15 shows an example of processing executed by the vehicle control device 2. The processing executed by the vehicle control device 2 will be described with reference to Fig. 15. Processing that differs from the processing shown in Fig. 4 will be described, and a description of processing that is the same as the processing shown in Fig. 4 will be omitted.

[0110] (Step S150) After the vehicle doors are unlocked in step S101, the wireless power supply authentication unit 204 generates an estimated remaining capacity calculation instruction to instruct the smartphone 3a to calculate an estimated remaining capacity of the battery 32 of the smartphone 3a, and outputs the estimated remaining capacity calculation instruction to the communication unit 21. The communication unit 21 transmits the estimated remaining capacity calculation instruction to the smartphone 3a.

[0111] As will be described later, upon receiving the instruction to calculate the estimated remaining amount, the smartphone 3a calculates the estimated remaining amount of the battery 32. The smartphone 3a transmits, to the vehicle control device 2, estimated remaining amount information indicating the estimated remaining amount.

[0112] (Step S151) The communication unit 21 of the vehicle control device 2 receives the estimated remaining amount information and outputs the estimated remaining amount information to the vehicle control unit 20.

[0113] (Step S152) The wireless power supply authentication unit 204 determines whether the estimated remaining amount indicated by the estimated remaining amount information is equal to or greater than a predetermined amount (for example, 5%). The predetermined amount is pre-stored in the storage unit 24. The predetermined amount is not limited to 5%. If the estimated remaining amount is equal to or greater than the predetermined amount, step S105 is executed. If the estimated remaining amount is less than the predetermined amount, step S102 is executed.

[0114] Fig. 16 shows an example of processing executed by the smartphone 3a. The processing executed by the smartphone 3a will be described with reference to Fig. 16. Processing that differs from the processing shown in Fig. 5 will be described, and a description of processing that is the same as the processing shown in Fig. 5 will be omitted.

[0115] (Step S250) If the authentication in step S200 is successful, the communication unit 31 receives an instruction to calculate the estimated remaining amount from the vehicle control device 2 and outputs the instruction to calculate the estimated remaining amount to the smartphone control unit 30.

[0116] (Step S251) After receiving the instruction to calculate the estimated remaining capacity, the battery control unit 303 checks the remaining capacity of the battery 32 and generates remaining capacity information indicating the remaining capacity.

[0117] (Step S252) After checking the remaining charge of the battery 32, the position measurement unit 35 measures the current position of the smartphone 3a and outputs current position information indicating the current position to the smartphone control unit 30a. The distance calculation unit 305 acquires the current position information.

[0118] (Step S253) After the current location information is acquired, the distance calculation unit 305 acquires information about the destination. For example, the distance calculation unit 305 acquires information about the destination input into the smartphone 3a by the user.

[0119] (Step S254) The distance calculation unit 305 acquires information on a point corresponding to the destination from map information, and calculates the distance from the current position to the destination (planned driving distance).

[0120] (Step S255) The remaining charge calculation unit 306 obtains from the storage unit 34 an estimated power consumption amount according to the travel distance corresponding to the distance calculated in step S254. The remaining charge indicated by the remaining charge information generated in step S251 indicates the current remaining charge of the battery 32. The remaining charge calculation unit 306 subtracts the estimated power consumption amount from the current remaining charge of the battery 32 to calculate the estimated remaining charge of the battery 32 when the vehicle arrives at the destination.

[0121] (Step S256) The remaining amount calculation unit 306 generates estimated remaining amount information indicating the estimated remaining amount calculated in step S255, and outputs the estimated remaining amount information to the communication unit 31. The communication unit 31 transmits the estimated remaining amount information to the vehicle control device 2. After step S256 is executed, step S201 is executed. If steps S102 to S104 shown in FIG. 15 are not executed, steps S201 to S203 are not executed.

[0122] As described above, the memory unit 34 of the smartphone 3a stores the estimated power consumption of the battery 32 according to the vehicle's travel distance. The position measurement unit 35 of the smartphone 3a measures the current location of the smartphone 3a. The distance calculation unit 305 of the smartphone 3a calculates the distance from the smartphone 3a's current location to the destination based on map information. The remaining power calculation unit 306 of the smartphone 3a obtains the estimated power consumption according to the calculated distance and the corresponding travel distance from the memory unit 34, and calculates the estimated remaining power of the battery 32 by subtracting the obtained estimated power consumption from the remaining power of the battery 32. The communication unit 31 of the smartphone 3a transmits estimated remaining power information indicating the estimated remaining power to the vehicle control device 2. The communication unit 21 of the vehicle control device 2 receives the estimated remaining power information. If the estimated remaining power indicated by the estimated remaining power information is less than a predetermined amount, the wireless power supply authentication unit 204 of the vehicle control device 2 determines whether the smartphone 3a supports wireless power supply. If it is determined that the smartphone 3a supports wireless power supply, the power supply unit 22 of the vehicle control device 2 starts wireless power supply to the smartphone 3a. This allows the vehicle control system 1 to prevent the remaining charge of the battery 32 of the smartphone 3a from running low while the vehicle is traveling.

[0123] (Modification of the third embodiment) A modified example of the third embodiment of the present invention will be described. In the modified example of the third embodiment, the smartphone 3a executes a determination regarding the estimated remaining amount. When the estimated remaining amount of the battery 32 is low, the smartphone 3a instructs the vehicle control device 2 to execute wireless power supply authentication.

[0124] Fig. 17 shows an example of processing executed by the vehicle control device 2. The processing executed by the vehicle control device 2 will be described with reference to Fig. 17. Processing that differs from the processing shown in Fig. 15 will be described, and a description of processing that is the same as the processing shown in Fig. 15 will be omitted.

[0125] In step S150, the vehicle control device 2 transmits an estimated remaining amount calculation instruction to the smartphone 3a. As will be described later, when the estimated remaining amount of the battery 32 is low, the smartphone 3a transmits a wireless power supply authentication instruction to the vehicle control device 2 to instruct the vehicle control device 2 to perform wireless power supply authentication.

[0126] (Step S160) After the estimated remaining power calculation instruction is sent to the smartphone 3a in step S150, the wireless power supply authentication unit 204 determines whether or not the wireless power supply authentication instruction has been received. If the wireless power supply authentication instruction has been received, step S103 is executed. If the wireless power supply authentication instruction has not been received, step S105 is executed.

[0127] Fig. 18 shows an example of processing executed by the smartphone 3a. The processing executed by the smartphone 3a will be described with reference to Fig. 18. Processing that differs from the processing shown in Fig. 16 will be described, and a description of processing that is the same as the processing shown in Fig. 16 will be omitted.

[0128] (Step S260) The wireless power supply authentication unit 302 determines whether the estimated remaining amount calculated in step S255 is equal to or greater than a predetermined amount (for example, 5%). The predetermined amount is pre-stored in the storage unit 34. The predetermined amount is not limited to 5%. If the estimated remaining amount is equal to or greater than the predetermined amount, step S203 is executed. If the estimated remaining amount is less than the predetermined amount, step S261 is executed.

[0129] (Step S261) If the estimated remaining amount is less than the predetermined amount, the wireless power supply authentication unit 302 generates a wireless power supply authentication instruction and outputs the wireless power supply authentication instruction to the communication unit 31. The communication unit 31 transmits the wireless power supply authentication instruction to the vehicle control device 2. After the wireless power supply authentication instruction is transmitted, step S201 is executed.

[0130] As described above, the memory unit 34 of the smartphone 3a stores the estimated power consumption of the battery 32 according to the vehicle's travel distance. The position measurement unit 35 of the smartphone 3a measures the current position of the smartphone 3a. The distance calculation unit 305 of the smartphone 3a calculates the distance from the current position to the destination based on map information. The remaining power calculation unit 306 of the smartphone 3a acquires, from the memory unit 34, the estimated power consumption according to the calculated distance and the corresponding travel distance, and calculates the estimated remaining power of the battery 32 by subtracting the acquired estimated power consumption from the remaining power of the battery 32. If the estimated remaining power is less than a predetermined amount, the communication unit 31 of the smartphone 3a transmits a wireless power supply authentication instruction (instruction information) to the vehicle control device 2 to instruct the vehicle control device 2 to determine whether or not the smartphone 3a is compatible with wireless power supply. The communication unit 21 of the vehicle control device 2 receives the wireless power supply authentication instruction. When the wireless power supply authentication instruction is received, the wireless power supply authentication unit 204 of the vehicle control device 2 determines whether or not the smartphone 3a is compatible with wireless power supply. If it is determined that the smartphone 3a supports wireless power supply, the power supply unit 22 of the vehicle control device 2 starts wireless power supply to the smartphone 3a. This allows the vehicle control system 1 to prevent the remaining charge of the battery 32 of the smartphone 3a from running low while the vehicle is traveling.
