An embodiment of an authentication system, a device control method, and a detection unit will be described below.
As shown in FIG. 1 , a vehicle 2 as an operated body 1 includes an authentication system 4 that performs user authentication and controls the operation of a device 3 of the operated body 1 . The authentication system 4 includes a first authentication function unit 6 that authenticates the electronic key 5 through first communication, which is communication with the electronic key 5 , and permits or executes the operation of the device 3 . The first authentication function unit 6 is, for example, preferably an electronic key system that authenticates the electronic key 5 using a verification device 7 provided on the operated body 1 . The device 3 is, for example, a door lock device, a steering lock device, an engine device, or the like.

The electronic key system includes, for example, a smart system that executes authentication processing triggered by communication from the operated body 1 and a wireless key system that executes authentication processing triggered by communication from the electronic key 5 . The smart system uses, for example, LF (Low Frequency) band radio waves for communication from the operated object 1 to the electronic key 5, and UHF (Ultra High Frequency) band radio waves for communication from the electronic key 5 to the operated object 1. The electronic key 5 is authenticated by smart communication using . The wireless key system remotely operates the operated object 1 by wireless communication that transmits radio waves to the operated object 1 when the electronic key 5 is operated, for example.

In this example, the communication executed by the smart system is referred to as "smart communication", and the authentication of the electronic key 5 by smart communication is referred to as "smart collation". Further, in the case of this example, communication executed by the wireless key system is referred to as "wireless communication", and authentication of the electronic key 5 by wireless communication is referred to as "wireless verification".

The ID information Did of the electronic key 5 registered in the operated body 1 is stored in a memory (not shown) of each of the electronic key 5 and the verification device 7 . The ID information Did includes, for example, an ID code of the electronic key 5, an encryption key used for encryption such as challenge-response authentication, and the like. The verification device 7 transmits radio waves communicated by the electronic key system from the transmission section 8 provided in the operated body 1 . The verification device 7 receives radio waves communicated by the electronic key system with a receiving section 9 provided in the operated body 1 .

The operated body 1 includes an operation detection unit 12 that detects an operation (user operation) performed by a user when operating the operated body 1 . The operation detection unit 12 includes, for example, a lock operation detection unit 13 that detects a user operation for locking the vehicle door, and an unlock operation detection unit 14 that detects a user operation for unlocking the vehicle door. The lock operation detection unit 13 is preferably, for example, a switch or a sensor that is provided on the exterior door handle 15 and detects a touch operation by a user's fingertip. The unlock operation detection unit 14 is preferably, for example, a sensor that is provided in the vehicle exterior door handle 15 and detects a grip operation of the vehicle exterior door handle 15 by the user. The operation detection unit 12 outputs a detection signal Sk to the verification device 7 via wiring 16 inside the vehicle.

When the verification device 7 detects an operation of the lock operation detection unit 13 or the unlock operation detection unit 14 by the user outside the vehicle, the verification device 7 performs smart communication (external smart communication) to authenticate the electronic key 5 with the electronic key 5 located outside the vehicle. communication). In the case of this example, when the verification device 7 detects an operation of the lock operation detection unit 13 or the unlock operation detection unit 14, the transmission unit 8, which transmits LF band radio waves to the outside of the vehicle, transmits radio waves to the electronic key 5. , to carry out smart communication outside the vehicle. When the electronic key 5 receives radio waves from the transmission unit 8 for external communication, the electronic key 5 responds to the verification device 7 with radio waves in the UHF band. Wireless smart matching between the electronic key 5 and the matching device 7 includes, for example, ID code authentication, challenge-response authentication, and the like.

When the verification device 7 detects that the lock operation detection unit 13 has been operated while the doors are unlocked, the verification device 7 establishes vehicle exterior smart verification and locks the vehicle doors. When the verification device 7 detects that the unlocking operation detection unit 14 has been operated while the doors are locked, the verification device 7 determines that the vehicle exterior smart verification is established and unlocks the vehicle door.

For example, when the verification device 7 detects an operation of the engine switch 17 in the driver's seat, the verification device 7 performs smart communication (in-vehicle smart communication) to authenticate the electronic key 5 with the electronic key 5 located inside the vehicle. In this example, when the verification device 7 detects the operation of the engine switch 17, the transmitter 8 that transmits LF band radio waves to the inside of the vehicle transmits radio waves to the electronic key 5 to perform in-vehicle smart communication. The verification device 7 permits the transition operation of the vehicle power supply when the in-vehicle smart verification is established. As a result, for example, when the engine switch 17 is pushed while the brake pedal of the driver's seat is depressed, the engine is started.

When locking and unlocking the vehicle door using the wireless key system, the operation button 18 provided on the electronic key 5 is operated. The operation button 18 includes, for example, a lock button and an unlock button. When the operation button 18 is operated, wireless communication is performed, and more specifically, an operation request is transmitted from the electronic key 5 to the verification device 7 using radio waves in the UHF band. The verification device 7 performs wireless verification by authenticating the operation request received from the electronic key 5, and locks and unlocks the vehicle door if the wireless verification is successful.

The authentication system 4 includes a second authentication function unit 22 that authenticates the terminal 21 through second communication, which is communication with the terminal 21 , and permits or executes the operation of the device 3 . Thus, the second authentication function unit 22 is, for example, a terminal key system that authenticates the terminal 21 instead of the electronic key 5 and controls the operation of the device 3 . The terminal 21 preferably has a main function different from the key function, and is preferably a terminal to which the key function is added separately. The terminal 21 is preferably a multifunctional terminal such as a high-performance mobile phone, for example.

The second authentication function unit 22 has a wireless authentication device 23 that controls the operation of the second authentication function unit 22 . The wireless authentication device 23 has a short-range wireless block 24 that authenticates the terminal 21 via short-range wireless communication. The short-range wireless block 24 includes an antenna 25 that performs short-range wireless communication with the terminal 21 and an authentication unit 26 that authenticates the terminal 21 . Authentication unit 26 authenticates terminal 21 by executing short-range wireless communication with terminal 21 via antenna 25 . The wireless authentication device 23 is preferably a product that can be retrofitted to the operated body 1 .

The short-range wireless communication may be PAN (Personal Area Network) communication or short-range wireless communication. Personal area network communication includes, for example, Bluetooth (registered trademark) communication, UWB (Ultra Wide Band) communication, and Wi-Fi (registered trademark) communication. Bluetooth communication is preferably BLE (Bluetooth Low Energy). Short-range wireless communication includes, for example, NFC (Near Field Communication) as a kind of RFID.

The terminal 21 includes a terminal control unit 29 that controls the operation of the terminal 21, an input unit 30 that is used when performing an input operation on the terminal 21, a display unit 31 that includes a display or the like, a memory 32 that can store data, It has a network communication unit 33 that communicates with the outside through network communication, and a communication module 34 that performs short-range wireless communication. The terminal 21 performs short-range wireless communication with the wireless authentication device 23 via the communication module 34 . The display unit 31 is, for example, a touch panel.

An application 35 necessary for operating the terminal 21 as a key of the operated body 1 is registered in the memory 32 of the terminal 21 . The application 35 is, for example, acquired from a server or the like through network communication, and written and stored in the memory 32 . By registering the application 35 in the terminal 21, it becomes possible to download the key information Dk to the terminal 21 and to operate the operated object 1 on the terminal 21. FIG.

The terminal 21 can be used as a key of the operated body 1 by registering the key information Dk necessary for authentication in the second authentication function unit 22 . The key information Dk is written and saved in the memory 32 . The terminal 21 preferably downloads the key information Dk by various methods such as download from a server, wireless acquisition from a master key, and image reading of code information. The key information Dk is, for example, a one-time key (one-time password) that is permitted to be used only once or for a certain period of time, a predetermined session key used as a key for encrypted communication, or the like. The key information Dk may be downloaded to the terminal 21 from the outside, or may be pre-written at the time of shipment.

The wireless authentication device 23 includes a verification device 7 and a smart communication block 36 that performs smart verification. The smart communication block 36 performs smart matching with the matching device 7 when the terminal 21 is authenticated by the short-range wireless block 24 . When executing smart verification with the smart communication block 36, the verification device 7 controls the operation of the device 3 based on whether or not this smart verification is established.

FIG. 2 illustrates an authentication communication sequence (second communication sequence) executed between the terminal 21 and the wireless authentication device 23 (the short-range wireless block 24).
At step 101, the short-range wireless block 24 periodically and repeatedly transmits Advertise for notifying information related to communication of the own device. Advertise is a type of packet data, for example, and is regularly transmitted from the short-range wireless block 24 at all times.

In step 102, when the terminal 21 receives the Advertise transmitted from the short-range wireless block 24, the terminal 21 performs scanning processing. It is preferable that the terminal 21 starts the scanning process, for example, when the received signal strength when receiving the advertisement reaches or exceeds a specified value. At this time, after the scanning process, the terminal 21 transmits a connection request to the wireless authentication device 23 as a request for providing details of the short-range wireless communication.

In step 103, when the terminal 21 and the short-range wireless block 24 perform the above exchanges, the short-range wireless communication is connected, that is, the communication connection state is entered.
In step 104, the terminal 21 and the short-range wireless block 24 authenticate the terminal 21 when the short-range wireless communication transitions to a communication connection state. In this example, for example, the terminal 21 transmits the key information Dk registered in the memory 32 to the short-range wireless block 24 by short-range wireless communication in response to the request from the short-range wireless block 24 . When the short-range wireless block 24 receives the key information Dk, the authentication unit 26 authenticates the key information Dk received from the terminal 21 . In the case of this example, the authentication unit 26 can correctly decrypt the key information Dk, and when the authentication of the key information Dk is established, for example, the usage time (usage start time/usage end time) of the operated body 1 , a session key to be used in subsequent short-range wireless communication, a terminal ID that is a unique ID of the terminal 21, and the like. On the other hand, if the key information Dk is not correct, the authentication unit 26 forcibly terminates the process and does not permit the use of the operated body 1 .

In step 105, when the key information Dk is authenticated, the terminal 21 and the short-range wireless block 24 enter an authentication completion state in which the establishment of authentication is recognized. The authentication completed state is a state in which both the terminal 21 and the short-range wireless block 24 know the common session key and terminal ID. This enables vehicle operations (door lock/unlock operation and engine start operation) using the terminal 21 .

FIG. 3 shows an example of the procedure for locking and unlocking the vehicle door using the terminal 21. As shown in FIG.
At step 201, the terminal 21 and the short-range wireless block 24 are shifted to an authentication completion state through short-range wireless communication.

In step 202, when the terminal 21 locks and unlocks the vehicle door, the terminal 21 transmits a remote operation request Sa corresponding to the operation to the short-range wireless block 24 by short-range wireless communication. The remote operation request Sa is an unlocking request signal when the vehicle door is to be unlocked. The remote operation request Sa is a lock request signal in the case of a vehicle door lock operation.

When the short-range wireless block 24 receives the remote operation request Sa from the terminal 21, if the short-range wireless block 24 is in the authentication completed state, the smart communication block 36 sends a wireless signal Sr1 based on this remote operation request Sa to It is transmitted to the verification device 7 by radio waves in the UHF band. That is, the smart communication block 36 transmits the wireless signal Sr1 corresponding to the remote operation request Sa to the verification device 7 when the short-range wireless block 24 is in the authentication completion state. The wireless signal Sr1 includes, for example, a command requesting the start of locking/unlocking operation and a unique ID code possessed by the smart communication block 36 . The communication for transmitting the wireless signal Sr1 from the smart communication block 36 to the verification device 7 is communication similar to the wireless communication executed between the electronic key 5 and the verification device 7 .

In step 203, upon receiving the wireless signal Sr1 from the smart communication block 36, the verification device 7 operates based on the wireless signal Sr1 to lock and unlock the vehicle doors. In the case of this example, the verification device 7 authenticates the ID code included in the wireless signal Sr1. If the ID code is correct, the wireless verification is established, and the doors are locked and unlocked according to the command. When the verification device 7 receives a door unlock request as a wireless signal Sr1 from the smart communication block 36, it unlocks the vehicle door, and when it receives a door lock request as a wireless signal Sr1 from the smart communication block 36, it locks the vehicle door. .

FIG. 4 illustrates an example of a procedure for starting the engine with smart engine start, which does not require operation of the terminal 21 when starting the engine of the vehicle 2 .
In step 301, when starting the engine, first, the terminal 21 and the short-range wireless block 24 are shifted to the authentication completed state in the same manner as when locking and unlocking the vehicle door.

In step 302, when the engine start permission operation is performed on the terminal 21, the terminal 21 transmits a permission request signal Sb corresponding to the operation to the short-range wireless block 24 by short-range wireless communication. The permission request signal Sb is a signal requesting the short-range wireless block 24 for permission to start the engine.

In step 303 , the verification device 7 performs smart verification with the smart communication block 36 of the wireless authentication device 23 when detecting that the engine switch 17 has been operated, for example. In this example, when the short-range wireless block 24 is in the authentication completion state and the short-range wireless block 24 receives the permission request signal Sb from the terminal 21, the smart communication block 36 performs smart matching with the matching device 7. to run. In this smart collation, for example, the ID code and encryption key registered in the smart communication block 36 are authenticated. Thus, the smart matching performed between verification device 7 and smart communication block 36 is similar to the smart matching performed between electronic key 5 and verification device 7 .

The verification device 7 permits the power transition operation (engine start operation) by the engine switch 17 when the smart verification with the smart communication block 36 is established. On the other hand, if the smart verification with the smart communication block 36 is not established, the verification device 7 does not permit the power transition operation (engine start operation) by the engine switch 17 .

In step 304, when the verification device 7 detects that the engine switch 17 is operated while depressing the brake pedal under the condition that smart verification is established between the verification device 7 and the smart communication block 36, the engine is started. switch. This makes it possible to drive the vehicle 2 .

As shown in FIG. 1, the authentication system 4 has a function (extended function) that enables smart operation of the operated body 1 (hands-free operation of the second authentication function unit 22) on the condition that a valid terminal 21 is possessed. I have. The extension function of this example is for realizing extension of the function without adding a special modification to the wireless authentication device 23, for example.

The authentication system 4 comprises a detection unit 39 that communicates with the terminal 21 based on the user's operation on the operated object 1 . The detection unit 39 is preferably, for example, a product that can be retrofitted to the operated body 1 . The detection unit 39 is electrically connected to the wiring 16 to which the detection signal Sk of the operation detection section 12 is output. The detection unit 39 may be mounted at any position on the operated body 1 as long as it is arranged at a position where communication with the terminal 21 is possible.

The detection unit 39 has a signal input 40 connected to the wiring 16 . The signal input unit 40 inputs the detection signal Sk output from the operation detection unit 12 via the wiring 16 .
The detection unit 39 includes a radio wave transmitter 41 capable of radio wave transmission to the terminal 21 via short-range wireless communication. In this case, the short-range wireless communication may use any communication such as Bluetooth, Wi-Fi, and UWB. Based on the detection signal Sk input by the signal input unit 40, the radio wave transmission unit 41 transmits an operation detection notification S1 corresponding to the detection signal Sk to the terminal 21. FIG. As described above, the detection unit 39 of this example is provided in the operated body 1, and when detecting a user operation on the operated body 1, transmits an operation detection notification S1 corresponding to the user operation to the terminal 21. FIG.

The authentication system 4 includes a transmission processing unit 42 for automatically transmitting a remote operation request S2 based on the operation detection notification S1 transmitted from the detection unit 39 from the terminal 21 to the operated object 1. FIG. The transmission processing unit 42 is provided in the terminal 21 (terminal control unit 29), for example. The transmission processing unit 42 is preferably functionally generated by the application 35 stored in the memory 32, for example. The transmission processing unit 42 communicates with the short-range wireless block 24 of the wireless authentication device 23 via short-range wireless communication.

In this example, when the terminal 21 receives the operation detection notification S1 transmitted from the detection unit 39, the transmission processing unit 42 transmits a remote operation request S2 corresponding to the operation detection notification S1 from the terminal 21 to the operated object. 1 automatically and causes the operated body 1 to perform an operation based on the user's operation. The remote operation request S2 is preferably a signal including, for example, a terminal ID, which is a unique ID of the terminal 21, a command requesting locking/unlocking, and the like. When the short-range wireless block 24 receives the remote operation request S2 transmitted from the terminal 21, the wireless authentication device 23 sends a wireless signal Sr2 corresponding to the remote operation request S2 to the verification device 7 via the smart communication block 36. to cause the verification device 7 to perform an operation according to the wireless signal Sr2.

Next, the operation of the authentication system 4 (hands-free operation of the second authentication function unit 22) of this embodiment will be described.
First, as a premise, for example, the detection unit 39 is not installed in the vehicle 2, which is the operated object 1, at the initial stage. A detection unit 39 is added. Also, if necessary, the application 35 of the terminal 21 is updated so that the hands-free operation of the second authentication function unit 22 can be executed.

As shown in FIG. 5, it is assumed that the user carrying the terminal 21 approaches the vehicle 2 . At this time, when the terminal 21 receives the Advertise transmitted from the short-range wireless block 24 of the wireless authentication device 23 and the received signal strength reaches or exceeds a specified value, communication between the terminal 21 and the short-range wireless block 24 is started. . Then, when the authentication unit 26 of the short-range wireless block 24 authenticates the terminal 21 and confirms that the terminal 21 is legitimate, the terminal 21 and the short-range wireless block 24 shift to the authentication completed state.

As shown in FIG. 6, it is assumed that the user holding the terminal 21 touches the outside door handle 15 to unlock the vehicle door. The unlocking operation detecting unit 14 as the operation detecting unit 12 outputs a detection signal Sk based on the touch operation to the wiring 16 when detecting an unlocking touch operation on the exterior door handle.

When the detection signal Sk is output from the unlocking operation detection section 14 , the detection unit 39 receives the detection signal Sk at the signal input section 40 . Then, when the detection signal Sk indicating that an unlocking operation has been performed is input by the signal input unit 40, the detection unit 39 transmits an operation detection notification S1 notifying that effect to the terminal 21 by short-range wireless communication. . If the user operation is an unlock operation, the operation detection notification S1 is an unlock operation detection notification that notifies that the vehicle 2 has been unlocked.

In this case, the operation detection notification S1 is preferably transmitted, for example, on the Advertise periodically transmitted by the detection unit 39 . That is, it is preferable that the radio wave transmission unit 41 include the operation detection notification S1 in the advertisement periodically transmitted by the detection unit 39 and transmit the advertisement to the terminal 21 . In this case, the detection unit 39 may use a communicator that only sends advertisements. Therefore, the terminal 21 can receive the operation detection notification S<b>1 transmitted from the detection unit 39 without going through the process of connecting the detection unit 39 to the terminal 21 .

Also, the detection unit 39 is not limited to taking the action of periodically transmitting advertisements. For example, the detection unit 39 may operate to transmit the operation detection notification S1 to the terminal 21 when the detection signal Sk is input from the operation detection section 12 as a trigger. In this case, it is advantageous for avoiding radio wave collision in short-range wireless communication.

As shown in FIG. 7, when the terminal 21 receives the operation detection notification S1 transmitted from the detection unit 39, the terminal 21 transmits a remote operation request S2 to the operated body 1 in accordance with the operation detection notification S1. This transmission operation is executed by the transmission processing unit 42 of the terminal 21 . At this time, since the terminal 21 and the wireless authentication device 23 are in a communication connection state, the short-range wireless block 24 of the wireless authentication device 23 can receive the remote operation request S2 from the terminal 21. It is possible.

The remote operation request S2 is a request signal for causing the operated body 1 to execute the user operation performed on the operated body 1 . Further, the remote operation request S2 is transmitted from the terminal 21 to the wireless authentication device 23 in the process of regular exchange of radio waves after the short-range wireless communication between the terminal 21 and the wireless authentication device 23 becomes a communication connection. preferably. When the user's operation is an unlocking operation, the remote operation request S2 is an unlocking remote operation request for requesting the vehicle 2 to perform an unlocking operation. Further, the remote operation request S2 may be the same signal as the aforementioned remote operation request Sa, or may be a different signal.

When the short-range wireless block 24 receives the remote operation request S2 transmitted from the terminal 21, the smart communication block 36 transmits a wireless signal based on this remote operation request S2 if the wireless authentication device 23 is in an authentication completed state. Sr2 is transmitted to the verification device 7 by radio waves in the UHF band. Smart communication block 36 transmits wireless signal Sr2 to verification device 7 via wireless communication with verification device 7 .

The wireless signal Sr2 includes, for example, a command requesting the initiation of an operation corresponding to a user's operation and a unique ID code possessed by the smart communication block 36. FIG. If the user's operation is an unlocking operation, the wireless signal Sr2 is a door unlock request requesting that the vehicle 2 perform an unlocking operation. The wireless signal Sr2 may be the same signal as the wireless signal Sr1 described above, or may be a different signal.

When receiving the wireless signal Sr1 from the smart communication block 36, the verification device 7 operates based on the wireless signal Sr1 to lock and unlock the vehicle doors. In the case of this example, the verification device 7 unlocks the vehicle door when receiving the door unlocking request as the wireless signal Sr2. As described above, even when the user gets into the vehicle 2 with the terminal 21 in hand, it is possible to unlock the door and get into the vehicle without operating the terminal 21 separately.

When the vehicle door is locked by the hands-free operation of the terminal 21, the same processing is executed with respect to the unlocking of the vehicle door, except that the locking and unlocking operations are different. Therefore, the explanation of unlocking the vehicle door is omitted with the explanation of locking the vehicle door.

According to the authentication system 4 of the above embodiment, the following effects can be obtained.

FIG. When the terminal 21 receives the operation detection notification S1 transmitted from the detection unit 39, the transmission processing unit 42 automatically transmits a remote operation request S2 corresponding to the operation detection notification S1 from the terminal 21 to the operated object 1. to cause the operated body 1 to perform an operation based on the user's operation.
