Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The same or corresponding parts in the drawings are designated by the same reference numerals, and the description thereof will not be repeated.

(First Embodiment)
FIG. 1 is an overall configuration diagram of a vehicle rental system according to the first embodiment. As shown in FIG. 1, the vehicle 1 includes an electronic key system 4 that performs ID verification wirelessly with the electronic key 2 to execute or permit the operation of the in-vehicle device 3. The electronic key system 4 is a smart key system that executes ID collation (smart collation) by narrow-range radio in the wake of communication from the vehicle 1. In the smart key system, ID verification is automatically performed without directly operating the electronic key 2. The in-vehicle device 3 is, for example, a door lock device 5 or an engine 6.

The vehicle 1 includes a collation ECU (Electronic Control Unit) 7 for ID collation, a body ECU 8 for controlling in-vehicle electrical components, and an engine ECU 9 for controlling the engine 6. The collation ECU 7, the body ECU 8 and the engine ECU 9 are electrically connected via a communication line 10 in the vehicle. The communication line 10 is, for example, CAN (Controller Area Network) or LIN (Local Interconnect Network). In each memory (not shown) of the collation ECU 7 and the electronic key 2, the electronic key ID of the electronic key 2 registered in the vehicle 1 and the electronic key unique key used at the time of ID verification authentication are registered. The body ECU 8 controls a door lock device 5 that locks and unlocks the vehicle door.

The vehicle 1 includes a transmitting unit 11 for transmitting radio waves and a receiving unit 12 for receiving radio waves. The transmission unit 11 includes, for example, an outdoor use for transmitting radio waves to the outside of the vehicle interior and an indoor use for transmitting radio waves to the inside of the vehicle interior. The transmission unit 11 transmits radio waves in the LF (Low Frequency) band. The receiving unit 12 receives radio waves in the UHF (Ultra High Frequency) band. The electronic key system 4 communicates with the electronic key 2 by bidirectional communication of LF-UHF.

When the wake signal for activating the electronic key 2 is LF transmitted from the transmission unit 11, when the electronic key 2 enters the communication area of the wake signal and receives it, the electronic key 2 is activated from the standby state and collates with the collation ECU 7 (smart). Collation) is executed. Smart verification includes, for example, electronic key ID verification for confirming the correctness of an electronic key ID, challenge-response authentication using an electronic key unique key (encryption key), and the like. When the collation ECU 7 confirms that the ID collation (outdoor smart collation) is established with the electronic key 2 outside the vehicle interior, the body ECU 8 permits the vehicle door to be locked and unlocked.

When the collation ECU 7 confirms that the ID collation (indoor smart collation) is established with the electronic key 2 in the vehicle interior, the collation ECU 7 transmits a signal permitting the operation of the engine 6 to the engine ECU 9. As a result, for example, when the engine switch is operated with the brake pedal depressed, the engine 6 starts.

The vehicle 1 can be compatible with a car sharing system in which one vehicle 1 is shared by a plurality of people (vehicles are rented out). The car sharing system is a system capable of renting one vehicle to a plurality of people, and is an example of the "vehicle rental system" in the present disclosure. In the car sharing system of the present embodiment, a rental key 30 (hereinafter, also referred to as an NFC card 30) composed of an IC card capable of short-range wireless communication (NFC: Near Field Communication) is mounted on the vehicle 1. It is realized by communicating with the device 14 using short-range wireless communication (NFC).

In the present embodiment, the car sharing device 14 has a configuration independent of the hardware configuration of the electronic key system 4 of the vehicle 1. The car sharing device 14 includes a share ECU 15 that controls the operation of the car sharing device 14, a BLE communication unit 17 that performs short-range wireless communication (BLE: Bluetooth Low Energy), and an NFC communication unit that performs short-range wireless communication (NFC). It includes 18 and a storage unit 19. The share ECU 15 is connected to the collation ECU 7 via a communication line 10. The storage unit 19 stores a unique key (encryption key) 20 and a unique ID 21 used for communication with the mobile terminal 40 and the NFC card 30. The unique key 20 and the unique ID 21 are pre-written in the memory (not shown) of the matching ECU 7. When the share ECU 15 and the collation ECU 7 are connected via the communication line 10, the unique key 20 and the unique ID 21 written in the collation ECU 7 are written in the storage unit 19.

The mobile terminal 40 includes a terminal control unit 41 that controls the operation of the mobile terminal 40, a network communication unit 42 that performs network communication in the mobile terminal 40, and a BLE communication unit 43 that performs short-range wireless communication (BLE). It includes an NFC communication unit 44 that performs wireless communication (NFC), a storage unit 45, and an input unit 46. For example, the mobile terminal 40 is a smartphone provided with a touch panel display corresponding to the input unit 46. However, the present invention is not limited to this, and any mobile terminal can be adopted as the mobile terminal 40, and may be a tablet terminal, a wearable device (for example, a smart watch), or the like. A common key for pairing is stored in the storage unit 45 of the mobile terminal 40 and the storage unit 19 of the car sharing device 14. The pairing of the mobile terminal 40 and the car sharing device 14 is performed by communicating with the BLE communication unit 43 or the NFC communication unit 44 of the mobile terminal 40 and the BLE communication unit 17 or the NFC communication unit 18 of the car sharing device 14 to obtain a common key. It is done using. When the pairing is completed, the unique key 20 and the unique ID 21 stored in the storage unit 19 of the car sharing device 14 are written in the storage unit 45 of the mobile terminal 40. After the unique key 20 and the unique ID 21 are written in the storage unit 45, the ID matching between the car sharing device 14 and the mobile terminal 40 is performed using the unique key 20 and the unique ID 21.

The rental key 30 (NFC card 30) is an IC card capable of communication by short-range wireless communication (NFC). In the present embodiment, the short-range wireless communication (NFC) is a short-range wireless communication defined by a standard such as "ISO / IEC18092", and performs non-contact communication within a distance of several cm. In the present embodiment, the short-range wireless communication (BLE) is a short-range wireless communication based on the Bluetooth (registered trademark) standard, and is a low power consumption communication mode added in the standard of Bluetooth 4.0 or later. In the embodiment, the communication distance is about several meters.

The NFC card 30 includes an antenna 31 and an IC chip 32. When the NFC card 30 is held over the NFC communication unit 18 of the car sharing device 14 or the NFC communication unit 44 of the mobile terminal 40 (when approaching a distance of several cm or less), the NFC communication unit 18 (NFC communication unit 44) An induced current is generated in the antenna 31 by the AC magnetic field generated from the antenna, and the IC chip 32 operates using this induced current as the electromotive force to enable communication between the NFC communication unit 18 (NFC communication unit 44) and the NFC card 30. .. When the NFC communication unit 18 (NFC communication unit 44) and the NFC card 30 can communicate with each other, the data stored in the NFC card 30 can be read and written. As described above, the NFC communication unit 18 and the NFC communication unit 44 have a reader / writer function of the NFC card 30, and the car sharing device 14 and the mobile terminal 40 operate as an "information writing device" of the NFC card 30.

FIG. 2 is a diagram showing data written in the memory area of the NFC card 30 (memory area of the IC chip 32). The authentication key storage area can store a common key and a unique key. The vehicle information registration area can store information indicating a unique key, a unique ID, and usage conditions. FIG. 3 is a diagram showing a step of writing data to the memory area of the NFC card 30 (hereinafter, may be abbreviated as S). When the NFC card 30 is held over the NFC communication unit 44 of the mobile terminal 40, power is supplied to the IC chip 32 and short-range communication (NFC) is connected (S1). When short-range communication (NFC) is connected, the common key information encrypted with the common key stored in the authentication key storage area of the NFC card 30 is transmitted to the mobile terminal 40 (S2). The mobile terminal 40 uses the common key stored in the storage unit 45 to decrypt and collate the received common key information. If the NFC card 30 is valid, the common keys of both are the same, and the collation is established (S3).

When the collation is established, the mobile terminal 40 reads the data of the unique key 20 and the unique ID 21 which are the vehicle information of the vehicle 1 from the storage unit 45 and transmits the data to the NFC card 30 (S4). Further, the mobile terminal 40 transmits to the NFC card 30 the usage conditions input by the user from the input unit 46, for example, information regarding the rental date and time and information regarding the number of times the vehicle has been used (S4). Then, the NFC card 30 writes the received unique key 20 in the authentication key storage area, and writes the received unique key 20, the unique ID 21, and the usage conditions in the vehicle information registration area (S5). In this way, writing of various data to the NFC card 30 is completed (S6). The unique ID is unique information of the vehicle 1, and may be, for example, a vehicle body number or the like.

When the vehicle information (unique key 20, unique ID 21) and usage conditions are written in the NFC card 30 (rental card 30) by the mobile terminal 40, the vehicle 1 can be rented using the NFC card 30. The user who has received the loan of the NFC card 30 can use the vehicle 1 by holding the NFC card 30 over the NFC communication unit 18 of the car sharing device 14. When the NFC card 30 is held over the NFC communication unit 18, power is supplied to the IC chip 32, and short-range communication (NFC) is connected. The unique key 20 and the unique ID 21 stored in the NFC card 30 match the unique key 20 and the unique ID 21 stored in the storage unit 19 of the car sharing device 14. Therefore, the ID verification between the NFC card 30 and the car sharing device 14 is established by the inquiry by the share ECU 15, and the authentication is completed. When this ID verification is established and the authentication is completed, the share ECU 15 determines whether or not the current use of the vehicle 1 satisfies the usage condition stored in the NFC card 30. When the share ECU 15 determines that the current use of the vehicle 1 satisfies the usage condition, the share ECU 15 transmits a permission signal permitting the use of the vehicle 1 to the matching ECU 7. Upon receiving the permission signal, the collation ECU 7 permits the body ECU 8 to unlock the vehicle door, and transmits a signal to the engine ECU 9 permitting the operation of the engine 6. As a result, the vehicle 1 can be used.

When the share ECU 15 transmits a permission signal permitting the use of the vehicle 1 to the collation ECU 7, the share ECU 15 rewrites the usage count data so that the usage count value stored in the vehicle information storage area of the NFC card 30 is reduced by one. The NFC communication unit 18 is provided, for example, on each of the window glass and the center console of the vehicle 1 that cannot be opened and closed, and the vehicle door is unlocked when the NFC card 30 is held over the NFC communication unit 18 provided on the window glass. It may be permitted, and the operation of the engine 6 may be permitted when the NFC card 30 is held over the NFC communication unit 18 provided on the center console. If the current use of the vehicle 1 does not satisfy the usage conditions stored in the NFC card 30, the share ECU 15 does not transmit a permission signal permitting the use of the vehicle 1 to the collation ECU 7, and the vehicle 1 is used. Do not allow. In this case, an alarm may be issued by an alarm device or the like (not shown).

In the present embodiment, vehicle information (unique key 20, unique ID 21) is stored in the storage unit 45 of the mobile terminal 40. Further, the usage conditions (rental date and time, number of times of use) can be input from the input unit 46 of the mobile terminal 40. Then, when the vehicle 1 is rented, the NFC card 30 (rental key 30) is held over the NFC communication unit 44 of the mobile terminal 40 to hold the vehicle information (unique key 20, unique ID 21) and use of the mobile terminal 40. Information on the conditions (rental date and time, number of uses) is written on the NFC card 30. By holding the NFC card 30 in which the vehicle information (unique key 20, unique ID 21) and information on the usage conditions (rental date and time, number of times of use) are written over the NFC communication unit 18 of the car sharing device 14, the unique key 20 and unique ID verification is performed using the ID 21, and the vehicle 1 can be used.

In this embodiment, vehicle information (unique key 20, unique ID 21) and usage conditions (rental date and time, number of times of use) are written on the NFC card 30 by using the short-range wireless communication (NFC) between the mobile terminal 40 and the NFC card 30. As a result, the NFC card 30 can be used as the rental key 30. The rental key 30 can be manufactured even in an environment where network communication is not possible, and the vehicle 1 can be rented without network communication. Therefore, the man-hours for constructing and developing a network communication system using a server or the like can be reduced, and the cost for maintaining the server or the like can also be reduced.

In this embodiment, the usage conditions are written on the NFC card 30. The usage condition is a condition for renting the vehicle 1, such as the date and time when the vehicle 1 can be used (rental date and time), the number of times of use, or the usable distance (travelable distance). If the usage conditions written on the NFC card 30 are no longer satisfied, for example, if the rental date and time is out of date or the number of times the vehicle 1 is used exceeds the number of times of use, the ID verification between the car sharing device 14 and the NFC card 30 is established. Even so, the share ECU 15 does not give permission to use the vehicle 1. That is, the NFC card 30 does not function as the rental key 30. (The NFC card 30 becomes invalid.) Therefore, it is possible to guarantee that the vehicle 1 is rented in the originally planned form, and it is possible to prevent the illegal rental (unauthorized use) of the vehicle 1.

The NFC card 30 of the present embodiment can be used as a rental key used for the valet parking service in which the vehicle 1 is deposited in the valet clerk. Depositing the electronic key 2 or the mobile terminal 40 to a valet clerk, such as a hotel boy, may raise concerns in terms of security, personal information protection, and the like. In this case, by depositing the NFC card 30 with the information that minimizes the number of times of use (for example, the number of times of use is set to 3) and the information that disallows unlocking the trunk room as the conditions of use to the bullet clerk. , It will be possible to eliminate these concerns.

In the present embodiment, the unique key 20 and the unique ID 21 stored in the storage unit 45 of the mobile terminal 40 are stored in the storage unit 19 of the car sharing device 14 after the pairing of the mobile terminal 40 and the car sharing device 14 is completed. The unique key 20 and the unique ID 21 that have been created are written in the storage unit 45 of the mobile terminal 40. On the other hand, by communicating via the network communication unit 42 of the mobile terminal 40, network communication is performed with the server specified by the user, the unique key 20 and the unique ID 21 stored in the server are downloaded, and stored in the storage unit 45. The unique key 20 and the unique ID 21 may be written.

In the present embodiment, the mobile terminal 40 corresponds to the "information writing device" and the car sharing device 14 corresponds to the "vehicle-mounted device".

(Second Embodiment)
In the first embodiment, vehicle information and usage conditions are written on the NFC card 30 by performing short-range wireless communication (NFC) between the mobile terminal 40 and the NFC card 30. In the second embodiment, vehicle information and information on usage conditions are written on the NFC card 30 by performing short-range wireless communication (NFC) between the car sharing device 14 and the NFC card 30. FIG. 4 is an overall configuration diagram of the vehicle rental system according to the second embodiment. The same configurations as those of the first embodiment shown in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted.

The vehicle 1 includes an input unit 22. The input unit 22 receives input from the user. The input unit 22 is operated by the user and outputs a signal corresponding to the user's operation to the share ECU 15. The communication method may be wired or wireless. Examples of the input unit 22 include various pointing devices, keyboards, touch panels, and the like. The input unit 22 may be an operation unit of a car navigation system, or may be a smart speaker that accepts voice input. The user can shift the car sharing device 14 to the registration mode by operating the input unit 22. In addition, the user can input usage conditions such as information on the rental date and time and information on the number of times the vehicle has been used by operating the input unit 22. The unique ID 21 is written in the storage unit 19 of the car sharing device 14, but the unique key 20 is not stored at first. (Although the unique ID 21 is written in advance in the collation ECU 7, the unique key 20 is not written.) The common key and the unique key 20 are stored in the authentication key storage area of the NFC card 30. The other configuration has the same configuration as that of the first embodiment, except that the mobile terminal 40 in the first embodiment is not essential.

FIG. 5 is a diagram showing a step of writing data to the memory area of the NFC card 30 in the second embodiment. The step shown in FIG. 5 starts when the user operates the input unit 22 and the car sharing device 14 shifts to the registration mode. When the NFC card 30 is held over the NFC communication unit 18 of the car sharing device 14, power is supplied to the IC chip 32 and short-range communication (NFC) is connected (S11). When short-range communication (NFC) is connected, the common key information encrypted with the common key stored in the authentication key storage area of the NFC card 30 and the information of the unique key 20 are transmitted to the car sharing device 14 (S12). The share ECU 15 uses the common key stored in the storage unit 19 to decode and collate the received common key information. If the NFC card 30 is valid, the common keys of both are the same, and the collation is established (S13).

When the collation is established, the share ECU 15 writes the received information of the unique key 20 in the storage unit 19 (S14). When the writing of the unique key 20 is completed, the share ECU 15 reads the data of the unique key 20 and the unique ID 21 as vehicle information from the storage unit 19 and transmits the data to the NFC card 30 (S15). Further, the share ECU 15 transmits to the NFC card 30 the usage conditions input by the user from the input unit 22, for example, information regarding the rental date and time and information regarding the number of times the vehicle has been used (S15). Then, the NFC card 30 writes the received unique key 20, unique ID 21, and usage conditions in the vehicle information registration area (S16). In this way, writing of various data to the NFC card 30 is completed (S17).

When the vehicle information (unique key 20, unique ID 21) and usage conditions are written in the NFC card 30 (rental card 30) by the share ECU 15, the vehicle 1 using the NFC card 30 is used as in the first embodiment. It can be rented out. The user who has received the loan of the NFC card 30 can use the vehicle 1 by holding the NFC card 30 over the NFC communication unit 18 of the car sharing device 14. Since the unique key 20 and the unique ID 21 stored in the NFC card 30 match the unique key 20 and the unique ID 21 stored in the storage unit 19 of the car sharing device 14, the NFC card is authenticated by the share ECU 15. ID matching between 30 and the car sharing device 14 is established. When this ID verification is established, the share ECU 15 determines whether or not the current use of the vehicle 1 satisfies the usage condition stored in the NFC card 30. When the share ECU 15 determines that the current use of the vehicle 1 satisfies the usage condition, the share ECU 15 transmits a permission signal permitting the use of the vehicle 1 to the matching ECU 7. Upon receiving the permission signal, the collation ECU 7 permits the body ECU 8 to unlock the vehicle door, and transmits a signal to the engine ECU 9 permitting the operation of the engine 6. As a result, the vehicle 1 can be used.

The NFC communication unit 18 is provided on each of the window glass and the center console of the vehicle 1 that cannot be opened and closed. If the registration mode shown in FIG. 5 is executed (the step of writing data to the memory area of the NFC card 30 is executed) while the NFC card 30 is held over the NFC communication unit 18 provided on the center console, the vehicle The NFC card 30 as the rental key 30 can be manufactured while ensuring the same operability as when the mobile terminal 40 of the first embodiment is used with the user in the first embodiment.

According to the second embodiment, the NFC card 30 as the rental key 30 can be manufactured without using the mobile terminal 40 while exhibiting the same operation and effect as the first embodiment.

When manufacturing a plurality of rental keys 30 (NFC card 30), as many unique keys 20 as the number to be manufactured are required. In the first embodiment, as many unique keys 20 as the number to be manufactured are stored in the storage unit 19 of the car sharing device 14 (when the unique key 20 is read and stored from the collation ECU 7 and stored in the memory of the collation ECU 7). You need to keep it. On the other hand, in the second embodiment, the unique key 20 is stored in the NFC card 30. In the second embodiment, the unique key 20 stored in the NFC card 30 is read out and written to the storage unit 19 of the car sharing device 14, so that it is necessary to store a plurality of unique keys 20 in the storage unit 19. No.

In the present embodiment, the car sharing device 14 corresponds to the "information writing device" and the "vehicle-mounted device".

(Modification example)
FIG. 6 shows an overall configuration diagram of a vehicle rental system according to a modified example. In the first embodiment, the share ECU 15 of the car sharing device 14 is connected to the collating ECU 7 by a communication line 10, and the car sharing device 14 is mounted on the vehicle 1 at the factory shipment stage of the vehicle 1. In the modified example shown in FIG. 6, the car sharing device 140 can be retrofitted to the vehicle 1. In the car sharing device 140, the smart communication unit 16 is added to the configuration of the car sharing device 14 of the first embodiment.

The electronic key ID and the electronic key unique key are stored in the storage unit 19 of the car sharing device 140, and the smart communication unit 16 and the transmission unit 11 and the reception unit 12 perform the same collation as the electronic key 2. Then, the communication between the share ECU 15 and the collation ECU 7 is established via the smart communication unit 16, the transmission unit 11, and the reception unit 12. The first embodiment except that the communication between the share ECU 15 and the collation ECU 7 is executed not via the communication line 10 in the first embodiment but through the smart communication unit 16, the transmission unit 11, and the reception unit 12. It works in the same way as the form. Therefore, in this modification, the vehicle 1 can be used for car sharing by retrofitting the car sharing device 140.

In each of the above embodiments, in the NFC card 30, an induced current is generated in the antenna 31 by an alternating magnetic field generated from the antenna of the NFC communication unit 18 (NFC communication unit 44), and the IC chip 32 uses this induced current as an electromotive force. Although described as a so-called "passive tag" type that operates, it may be an "active tag" type that has a power supply. For example, if the mobile terminal 40 is a smartphone equipped with an "active tag" type IC chip, the mobile terminal 40 can be used as a rental key.

In each of the above embodiments, it is also possible to manufacture a rental key using short-range wireless communication (BLE). For example, in the first embodiment and the second embodiment, the NFC card 30 is replaced with a smartphone, and the smartphone and the BLE communication unit 17 of the car sharing device 14 or the BLE communication unit 43 of the mobile terminal 40 and short-range wireless communication ( By performing BLE), vehicle information (unique key 20, unique ID 21) and usage conditions can be written on the smartphone, and the smartphone can be used as a rental key.

In each of the above embodiments, the share ECU 15 of the car sharing device 14 performs ID verification (authentication) with the NFC card 30, but the NFC card is used by the verification ECU 7 using information such as the unique key 20 and the unique ID 21.
