Hereinafter, one embodiment of a sharing system is described according to FIGS. 1 to 6.
As shown in FIG. 1, the vehicle 1 includes an electronic key system 4 that performs ID verification by wireless with the electronic key 2 and executes or permits the operation of the on-vehicle device 3. The electronic key system 4 is a key operation free system that executes ID verification (smart verification) by short-range wireless communication triggered by communication from the vehicle 1. In the key operation free system, ID verification is automatically performed without directly operating the electronic key 2. The in-vehicle device 3 includes, for example, a door lock device 5, an engine 6, an in-vehicle communication device 7, and the like. The in-vehicle communication device 7 is preferably a communication device capable of communication by Bluetooth (registered trademark), for example.

  The vehicle 1 includes a verification ECU (Electronic Control Unit) 9 that performs ID verification, a body ECU 10 that manages the power supply of in-vehicle electrical components, and an engine ECU 11 that controls the engine 6. These ECUs are electrically connected via a communication line 12 in the vehicle. The communication line 12 is, for example, a controller area network (CAN) or a local interconnect network (LIN). In each memory (not shown) of the verification ECU 9 and the electronic key 2, the electronic key ID of the electronic key 2 registered in the vehicle 1 and a key unique key used at the time of ID verification authentication are registered. The body ECU 10 controls a door lock device 5 that switches locking and unlocking of the vehicle door 13.

  The vehicle 1 includes a radio wave transmitter 16 for transmitting radio waves in the vehicle 1 and a radio wave receiver 17 for receiving radio waves in the vehicle 1. The radio wave transmitter 16 includes, for example, an outdoor unit that transmits a radio wave outdoors and an indoor unit that transmits a radio wave indoors. The radio wave transmitter 16 transmits radio waves in the LF (Low Frequency) band. The radio receiver 17 receives radio waves in the UHF (Ultra High Frequency) band. The electronic key system 4 communicates with the electronic key 2 by bi-directional communication of LF-UHF.

  When the wake signal for activating the electronic key 2 is LF transmitted from the radio wave transmitter 16, when the electronic key 2 enters the communication area of the wake signal and is received, the electronic key 2 is activated from the standby state, and ID collation with the verification ECU 9 ( Perform smart matching). The smart verification includes, for example, electronic key ID verification for confirming the correctness of the electronic key ID, challenge response authentication using a key unique key (encryption key), and the like. When the collation ECU 9 confirms that the ID collation (outdoor smart collation) is established with the outdoor electronic key 2, the collation ECU 9 permits or executes the locking and unlocking of the vehicle door 13 by the body ECU 10.

  When the collation ECU 9 confirms that ID collation (indoor smart collation) is established with the electronic key 2 in the room, the power supply transition operation by the engine switch 18 is permitted. Thus, for example, when the engine switch 18 is operated with the brake pedal depressed, the engine 6 is started.

  The vehicle 1 of the present example as a common item 24 shared by a plurality of people includes a sharing system 21 that realizes sharing among a plurality of people. In the sharing system 21 of this example, the encrypted key information Dk is registered from the server 20 to the portable terminal 22, and the authentication device 23 having an encryption key (authentication device unique key) capable of decrypting the key information Dk is installed. The key information Dk is transmitted from the portable terminal 22 to the vehicle 1 and authenticated by the authentication device 23. If the authentication is established, the operation of the operation target 25 provided on the vehicle 1 is permitted.

  The mobile terminal 22 is preferably, for example, a high-performance mobile phone. The key information Dk is preferably, for example, a one-time key (one-time password) whose use is permitted only once. The operation target 25 is, for example, a door lock device 5 (vehicle door 13), a vehicle power supply (engine 6), an in-vehicle communication device 7 or the like. The on-vehicle communication device 7 can communicate with a wearable terminal or the like worn by the driver through, for example, Bluetooth communication.

  The authentication device 23 controls the operation of the sharing system 21 and is independent of the hardware configuration of the electronic key system 4 of the vehicle 1. The authentication device 23 is connected by wire to a component of the electronic key system 4 through a wire 31 (for example, a lead wire), and power is supplied from the battery + B of the vehicle 1. The authentication device 23 is, for example, wired connected to various ECUs such as the verification ECU 9 or wired connected to the communication line 12 in the vehicle.

  The mobile terminal 22 includes a terminal control unit 26 controlling operation of the mobile terminal 22, a network communication module 27 performing network communication in the mobile terminal 22, and a short distance wireless communication module 28 performing short distance wireless communication in the mobile terminal 22. , And a memory 29 capable of rewriting data. The portable terminal 22 acquires key information Dk from the server 20 by the network communication module 27 and writes the key information Dk in the memory 29 for storage. The near field communication is preferably Bluetooth, for example.

  The mobile terminal 22 includes a user interface application 30 that manages the operation of the sharing system 21 in the mobile terminal 22. The user interface application 30 is provided in the terminal control unit 26, for example, downloaded from the server 20. In the memory 29 of the portable terminal 22, a user authentication key required at the time of communication when operating the vehicle 1 by the portable terminal 22 is registered. The user authentication key is, for example, a random number whose value changes every time it is generated, and may be registered in advance in the sharing system 21 or may be generated and registered when the vehicle is used.

  The authentication device 23 includes a controller 33 for controlling the operation of the authentication device 23, a short distance wireless module 35 for performing short distance wireless communication in the authentication device 23, a memory 36 capable of rewriting data, and a date and time in the authentication device 23. And a timer unit 37 for managing. In the memory 36, an authentication device ID which is a unique ID of each authentication device 23 and an authentication device unique key used for encrypted communication with the portable terminal 22 are written and stored. The timer unit 37 includes, for example, a soft timer. The authentication device 23 is in one-to-one correspondence with the vehicle 1 by associating the authentication device ID with the vehicle ID (body number).

  The authentication apparatus unique key is a type of key used to authenticate the key information Dk of the mobile terminal 22. A plurality of authentication device unique keys are written and stored in the memory 36 of the authentication device 23. This is to make one authentication device 23 operable in a plurality of mobile terminals 22 (in this example, the first mobile terminal 22a and the second mobile terminal 22b). This is not limited to a scene in which the share vehicle 1 is driven by only one first portable terminal 22a, for example, returning to the share vehicle 1 by another second portable terminal 22b while using the share vehicle 1 The shared vehicle 1 is sent automatically by short distance wireless transmission of biological information (pulse information) acquired by the watch-type second portable terminal 22b (so-called wearable terminal) while putting in luggage or using the share vehicle 1 This is to realize the function of stopping or the like. In the case of this example, in the memory 36, for example, an authentication apparatus unique key A, an authentication apparatus unique key B,.

  The authentication device 23 includes an operation control unit 38 that operates the in-vehicle device 3 through communication with the portable terminal 22. The operation control unit 38 is provided in the controller 33. The operation control unit 38 controls the operation of various devices of the vehicle 1 when it is switched to the “authentication completed state” through communication with the portable terminal 22.

  The sharing system 21 includes a multiple use permission unit 40 that enables the common item 24 to be operated by a plurality of portable terminals 22 owned by each person. The multiple use permitting unit 40 is provided in the controller 33 of the authentication device 23. The plural use permitting unit 40 of this example confirms whether or not the key information Dk can be correctly decoded by using a plurality of authentication apparatus unique keys, and the common item 24 can be operated by the portable terminal 22 that can be decoded. By doing this, the common item 24 can be operated across a plurality of portable terminals 22.

  Next, the operation and effects of the sharing system 21 of the present embodiment will be described using FIGS. 2 to 6. First, using FIG. 2, a procedure for reservation registration of the portable terminal 22 as a vehicle key will be described. Here, for example, an example in which the main user registers the portable terminal 22 (first portable terminal 22a) in the authentication device 23 will be described.

  In step 101, the mobile terminal 22 (user interface application 30) and the server 20 execute user authentication to confirm the user who reserves the vehicle 1. In the user authentication of this example, authentication of the user ID and password and a use reservation procedure for registering the vehicle 1 to be reserved are performed. In the use reservation procedure, for example, the vehicle 1 to be used, the date and time, etc. are input. The user ID and password are input to the mobile terminal 22 and transmitted to the server 20 through network communication. When the user 20 inputs a user ID and a password from the portable terminal 22, the server 20 authenticates these, and if the authentication is established, the process is continued, and if the authentication is not established, the process is forcibly terminated.

  In step 102, when user authentication is established, the server 20 generates key information Dk. The server 20 generates key information Dk using, for example, an authentication device unique key of the authentication device 23 mounted on the vehicle 1 used by the user. In the case of this example, the server 20 uses, for example, “reservation date and time”, “terminal ID”, “user authentication key”, “time information”, and “permission function” as plain text, and a predetermined encryption key (in this example, an authentication device Using a unique key as an encryption key, a ciphertext is generated by passing them through a cryptographic expression (cipher algorithm), and this ciphertext is used as key information Dk.

  Here, since an example in which the main user performs registration work of the portable terminal 22 is given, “A”, for example, is used as the authentication apparatus unique key. The terminal ID is a unique ID of the portable terminal 22. The user authentication key is, for example, a key for which a different value is generated each time the user is generated, and is a type of key used in encrypted communication between the portable terminal 22 and the authentication device 23. The time information is information used to correct the time of the timer unit 37 of the authentication device 23.

  The permission function is a function requested by the user to be used during the use procedure, that is, a function whose operation is permitted by the server 20 among various operations on the vehicle 1. When the main user performs an operation of registering his / her portable terminal 22 as a vehicle key, it is preferable that “smart operation function” is set as the permission function. The smart operation is an operation of operating the vehicle 1 by the above-described key operation free system.

In step 103, the server 20 transmits the generated key information Dk to the portable terminal 22 via a network.
In step 104, the portable terminal 22 (user interface application 30) and the authentication device 23 execute connection of near field communication (BLE: Bluetooth Low Energy). Here, the authentication device 23 periodically transmits an advertisement. The portable terminal 22 transmits a communication connection request to the authentication device 23 when receiving the advertisement within the reservation time to borrow the vehicle 1. When receiving the communication connection request from the portable terminal 22, the authentication device 23 transmits, to the portable terminal 22, a communication connection confirmation for notifying the other party that the communication has been established. Thereby, BLE communication of the portable terminal 22 and the authentication device 23 is established.

In step 105, when the communication connection (BLE connection) is completed, the authentication device 23 transmits a key information request for requesting notification of the key information Dk registered in the portable terminal 22.
In step 106, when receiving the key information request from the authentication device 23, the portable terminal 22 (user interface application 30) transmits a key information notification for notifying the authentication device 23 of the key information Dk registered therein.

  In step 107, when receiving the key information Dk from the portable terminal 22, the authentication device 23 executes an authentication operation of the key information Dk. In the case of this example, the multiple use permitting unit 40 decrypts the key information Dk using the authentication device unique key registered in the authentication device 23. Here, a plurality of authentication device unique keys A, B,... Are registered in the memory 36 of the authentication device 23 of this example. Therefore, the multiple use permitting unit 40 decrypts the key information Dk by sequentially decrypting with the authentication apparatus unique key. Then, if the decryption of the key information Dk is successful, the multiple-use permission unit 40 determines that the key information Dk received from the portable terminal 22 is correct and the authentication is successful. On the other hand, if the authentication is not established, the multiple-use permission unit 40 determines that the key information Dk is not correct, fails the authentication, and disconnects the connection of BLE communication.

In step 108, when the authentication operation of the key information Dk is completed, the authentication device 23 executes the user authentication key notification of notifying the portable terminal 22 of the user authentication key.
In step 109, when the portable terminal 22 (user interface application 30) acquires the user authentication key, it transmits a key function on request to the authentication device 23. The key function on request is a request for switching the operation control unit 38 of the authentication device 23 to the on state (valid state).

  In step 110, when receiving the key function on request from the portable terminal 22, the authentication unit 23 switches the operation control unit 38 to the on state. As a result, the authentication device 23 is in a state in which the in-vehicle device 3 can be operated.

  In step 111, the authentication device 23 stores the key information Dk and the user authentication key in the memory 36 of the authentication device 23 after the operation control unit 38 is switched to the on state. Then, the portable terminal 22 and the authentication device 23 shift to the “authentication completed state”. As described above, the authentication device 23 is in a state capable of vehicle door locking and unlocking and engine start operation.

  Here, as shown in FIG. 3, when the main user lends out the share vehicle 1 to another user (third party etc.), the main user operates the first mobile terminal 22a of his own, and the lending procedure of the share vehicle 1 is performed. I do. In this lending procedure, the main user first performs user authentication with the server 20 by operating the first mobile terminal 22a of the main user. After completion of user authentication, the main user inputs to the first mobile terminal 22a the reservation date (use date) desired by the other user, the terminal ID of the second mobile terminal 22b possessed by the other user, the permission function for lending to the other user, etc. Do. The first portable terminal 22a may obtain such information from the second portable terminal 22b of another user through communication. The second portable terminal 22b in this example is, for example, positioning of a bullet key.

  When only the locking / unlocking of the vehicle door 13 is permitted to lend the permission function to another user, “request for permission for locking / unlocking the vehicle door” is input and when only starting of the engine 6 is permitted, “engine start” When "permission request" is input and operation of the vehicle power supply is permitted until ACC transition, "ACC transition permission request" is input. In addition, when the Bluetooth communication function of the vehicle 1 is permitted, “Bluetooth communication permission request” is input.

  After entering the necessary items, the main user sends a lending procedure request to the server 20. When the server 20 receives the lending procedure request from the first portable terminal 22a, the server 20 generates key information Dk based thereon. In the case of this example, the server 20 uses, for example, “reservation date and time”, “terminal ID”, “user authentication key”, and “permission function” as plain text, and an encryption key different from the above (this example is an authentication device unique key). Cipher) is used as an encryption key, and a ciphertext is generated by passing them through a cipher equation (cipher algorithm), and this ciphertext is used as key information Dk.

  Here, an example is given in which the share vehicle 1 can be operated by the second mobile terminal 22b of another user, so that “B”, for example, is used as the authentication apparatus unique key. Further, in the permission function included in the key information Dk at this time, the permission request input by the main user at the first portable terminal 22a is written when lending the permission function to another user. For example, when only locking and unlocking the vehicle door 13 is permitted when the vehicle 1 is rented, “vehicle door locking and unlocking permission” is written as the permission function.

  The server 20 performs network transmission of the generated key information Dk to the second mobile terminal 22 b of the other user. Then, the second mobile terminal 22b of the other user authenticates the key information Dk with the authentication device 23, and if it can correctly decrypt the key information Dk, the second mobile terminal 22b shifts to the authentication completed state. That is, since the multiple use permitting unit 40 can correctly decrypt the key information Dk with the authentication apparatus unique key B, the multiple use permitting unit 40 permits the vehicle operation at the second portable terminal 22b. In addition, since the process performed at this time is the same as that of above-mentioned step 104-step 111, description is abbreviate | omitted.

  Here, when it is preferable to set the use limit time in the permission function, the key information Dk includes time information Tr (in this example, reservation date and time information). This is because, for example, the permission function (smart operation function, vehicle door locking / unlocking function, engine start function, ACC transition request) related to the vehicle travel system is not good in terms of securing the security against the vehicle theft if the use is permitted unlimitedly. In the case of these functions, it is better to have a time limit for use.

  On the other hand, as shown in FIG. 4, when it is not necessary to set the use restriction in the permission function, the key information Dk does not include the time information Tr (in this example, the reservation date and time information). As described above, in the case of this example, the reservation date and time is an option (selection type) in which setting presence / absence is selected according to the permitted function designated by the user. Therefore, the permission function (for example, the Bluetooth communication function) having no time concept for use can be freely used anytime regardless of time.

  Here, as shown in FIG. 5, when the key information Dk of the portable terminal 22 (the first portable terminal 22a, the second portable terminal 22b) in which the permission function related to the vehicle travel system is set can be correctly decoded, The “reservation date, terminal ID, user authentication key, time information, permission function” included in the key information Dk can be acquired. That is, the reservation date and time, the terminal ID, the user authentication key, the time information, and the permission function can be linked to the portable terminal 22 that has successfully decoded the key information Dk. Therefore, it is possible to cause the authentication device 23 to recognize the date and time when, for example, the smart function, the locking and unlocking function of the vehicle door 13, the engine start function, the ACC transition function of the vehicle power supply, and the like can be used.

  On the other hand, when the key information Dk of the portable terminal 22 (the first portable terminal 22a, the second portable terminal 22b) for which the permission function having no time concept is set is successfully decoded, the key information Dk is included. "Terminal ID, user authentication key, permission function" can be acquired. That is, the terminal ID, the user authentication key, and the permission function can be linked with respect to the portable terminal 22 that has successfully decoded the key information Dk except for the parameters of the time information Tr.

  As shown in FIG. 6, in step 201, it is assumed that the user has operated the operation request button on the portable terminal 22 that has shifted to the authentication completed state. The operation request button includes various buttons corresponding to the permission function, such as a smart operation request button, a door unlock request button, a door lock request button, an engine start request button, an ACC transition request button, and a wireless communication request button. The operation request button is preferably a button displayed on the touch panel of the mobile terminal 22.

  In step 202, when the portable terminal 22 (user interface application 30) detects that the operation request button has been operated on the portable terminal 22, it encrypts the operation request signal corresponding to the operation request button with the user authentication key. The operation request signal is a signal including a command, a terminal ID and the like corresponding to the operated operation request button.

In step 203, the portable terminal 22 (user interface application 30) transmits the encrypted operation request signal to the authentication device 23 via short distance wireless communication.
In step 204, when receiving the operation request signal from the portable terminal 22, the authentication device 23 controls the operation of the in-vehicle device 3 based on this signal. In the case of this example, the operation control unit 38 identifies the portable terminal 22 from the received terminal ID. Then, the operation control unit 38 executes the operation of the permission function according to the acquired terminal ID.

  By the way, the 1st portable terminal 22a is positioning of the vehicle key which a main user uses. Therefore, it is preferable that the permission function registered in the first portable terminal 22a is a smart operation function that can operate the vehicle 1 freely.

  Here, it is assumed that a smart operation request signal is transmitted to the authentication device 23 as an operation request signal from the first portable terminal 22a in a position where the vehicle 1 can be operated freely. In this case, since the operation control unit 38 receives the smart operation request signal from the first portable terminal 22 a, the operation control unit 38 outputs the smart operation permission to the verification ECU 9 through the wiring 31. The verification ECU 9 switches to the state of the smart operation permission by receiving the effect of the smart operation permission from the operation control unit 38. Therefore, under the external smart verification, the vehicle door 13 is unlocked if the outside door handle is touched, and the vehicle door 13 is locked if the lock button on the outside door handle is operated. Further, when the engine switch 18 is operated while the brake pedal is depressed while the indoor smart verification is established, the engine 6 is started.

  In addition, the second portable terminal 22b is positioning of the bullet key. This is because, as a main user's request, there is a situation where it is desired to permit only some functions, instead of permitting other users to use the entire vehicle 1 entirely. Therefore, for the second portable terminal 22b used by other users, only the opening / closing operation of the vehicle door 13, only the operation of switching the vehicle power to ACC to listen to the music by the in-vehicle audio, the in-vehicle wireless communication function (Bluetooth Allow only the operation to turn on the communication function). Therefore, it is preferable that the permission functions registered in the second mobile terminal 22b are functions of only door unlocking permission, only door locking permission, only engine start permission, only ACC transition permission, and only wireless communication permission.

  Here, it is assumed that a door unlocking request signal is transmitted to the authentication device 23 as an operation request signal from the second portable terminal 22b in the bullet key positioning. In this case, since the operation control unit 38 receives the door unlocking request signal from the second portable terminal 22b, the operation unlocking is output to the verification ECU 9 through the wiring 31 and the vehicle door 13 is released to the body ECU 10 Lock it. The notification of the door unlocking request may be output directly from the authentication device 23 to the body ECU 10, or may be output to the body ECU 10 through the communication line 12, for example. The body ECU 10 unlocks the vehicle door 13 based on the acquired door unlocking permission.

  Further, when the second mobile terminal 22 b is a wearable terminal, it is assumed that a wireless communication request signal is transmitted from the wearable terminal as an operation request signal to the authentication device 23. In this case, since the operation control unit 38 receives the wireless communication request signal from the wearable terminal, the operation control unit 38 outputs an indication of wireless communication permission to the in-vehicle communication device (not shown) through the wiring 31 and between the wearable terminal and the in-vehicle communication device. Switch to enable wireless communication. In the case of this example, use of the wireless communication function has no time limit and is always permitted. Therefore, when the wearable terminal operates the function of sequentially monitoring the biological information (pulse information), the detected biological information (pulse information) can be continuously sent from the wearable terminal to the vehicle 1 without time restriction.

  Furthermore, when the driving support function for automatically stopping the vehicle 1 at the time of abnormality is mounted on the vehicle 1, it is assumed that the driving support request signal is transmitted from the second portable terminal 22b to the authentication device 23. In this case, since the operation control unit 38 receives the driving support request signal from the second mobile terminal 22b, the operation control unit 38 outputs a driving support permission message to a device (not shown) that controls the driving support function. Here, if the driving support function is set so as not to be limited in time, it becomes possible to always operate the driving support function regardless of time.

  Now, in the case of this example, when operating the in-vehicle apparatus 3 of the share vehicle 1 with the portable terminal 22, the in-vehicle apparatus 3 can be operated not only by one portable terminal 22 but also by other portable terminals 22. Therefore, one share vehicle 1 can be operated by a plurality of portable terminals 22.

  The authentication device 23 includes a plurality of authentication device unique keys used for authentication of the key information Dk in the memory 36. The plural use permitting unit 40 confirms whether or not the key information Dk can be correctly decoded by using a plurality of authentication device unique keys, and the vehicle 1 can be operated by the portable terminal 22 that can be decoded, The vehicle 1 can be operated across a plurality of portable terminals 22. Therefore, the vehicle 1 can be operated by the plurality of portable terminals 22 by a simple method of registering a plurality of authentication device unique keys in the memory 36 of the authentication device 23.

  When the in-vehicle device 3 is operated by the portable terminal 22, the authentication device 23 identifies the portable terminal 22 from the terminal ID that each of the portable terminals 22 has.
