Description

  The present invention relates to a keyless authentication system and a vehicle with a keyless authentication system.

A keyless entry device for a vehicle includes a device (fixed unit) attached to the vehicle and a plurality of portable devices carried by a vehicle user. Each portable device has a unique identification number, and the identification number of the portable device forming the set is registered in the fixed unit.
In some keyless entry devices, the fixed unit communicates with the portable device only when the holder of the portable device approaches the door. In this communication, the mobile device is authenticated using the identification number, and if the authentication is successful, the fixed unit allows the door lock device to perform unlocking.

Some keyless entry devices have a request button attached to the door. When the user presses the request button, the fixed unit communicates with the portable device and uses the identification number to identify the portable device. Authenticate. If the authentication is successful, the fixed unit allows the door lock device to execute unlocking as in the previous case.
In addition, some keyless entry devices lock the engine start switch, and when the user tries to turn on the start switch, the fixed unit similarly authenticates the portable device. If the authentication is successful, the fixed unit unlocks the engine start switch.

If a plurality of portable devices are registered in the fixed unit, the fixed unit communicates with the portable devices one by one in an appropriate order, and repeats communication until authentication is established.
In this type of keyless entry device, the accuracy and speed of authentication affect vehicle operation. In particular, when a plurality of portable devices are registered in the fixed unit, the authentication success rate decreases, the authentication speed decreases, and problems such as the door not being easily opened or the engine being unable to start up quickly occur.

  Therefore, in the prior art, every time authentication is performed, the identification number of the portable device that has been successfully authenticated is stored, and in the next authentication, authentication is attempted with the highest priority on the portable device having the identification number that has been successfully authenticated last. (For example, refer to Patent Document 1 and Patent Document 2). This method is based on the idea that a target portable device to be authenticated is likely to be the same as a portable device that has succeeded in authentication in the past. According to this method, it is considered that the authentication success rate is surely increased, and as a result, the authentication speed (response time) is increased.

The transmitting antenna 22 is provided so that the in-vehicle unit 12 and the portable device 14 can communicate with each other when the portable device 14 is near the door outside the vehicle and when the portable device 14 is near the driver's seat in the vehicle. It has been. For this reason, for example, the communicable distance of each transmission antenna 22 is appropriately limited.

[Input device]
The engine start request button 26 and the door unlock request button 28 are input devices for receiving commands from the user.
Specifically, for example, a brake pedal can also serve as the engine start request button 26. By depressing the brake pedal, the user can operate an engine start switch provided separately from the engine start request button 26, and can start the engine.
The engine start switch can be provided on the dashboard or steering column in the vehicle.

  The door unlocking request button 28 is provided, for example, integrally with a door knob outside the vehicle or in the vicinity of the door knob. When the user touches the door unlock request button 28, a door unlock command is input to the in-vehicle device 20.

[In-vehicle machine]
The in-vehicle device 20 includes, for example, an in-vehicle device control unit 30 composed of a CPU (Central Processing Unit), an input unit 32, an output unit 34, an in-vehicle device memory 36, a transmission unit 38, and a reception unit 40, and the in-vehicle device control unit. 30, an input unit 32, an output unit 34, an in-vehicle device memory 36, a transmission unit 38, and a reception unit 40 are electrically connected to each other.

  The input unit 32 inputs commands received from the user by the engine start request button 26 and the door unlock request button 28 to the in-vehicle device control unit 30. The in-vehicle device control unit 30 causes the transmission unit 38 and the transmission antenna 22 to transmit an authentication request signal when a command is input from the input unit 32. The authentication request signal includes a code for specifying the portable device 14 to be communicated for authentication and a code for making the portable device 14 respond.

When the portable device 14 to be communicated receives the authentication request signal, it transmits a response signal including a code corresponding to its own unique identification number. The receiving unit 40 receives the response signal via the receiving antenna 24 and inputs the identification number included in the received response signal to the in-vehicle device control unit 30.
The in-vehicle device control unit 30 compares the unique identification number of the portable device 14 included in the response signal with the identification number stored in the in-vehicle device memory 36, and when these match each other, the authentication of the portable device 14 is performed. Succeeds.

  If the authentication is successful, the in-vehicle device control unit 30 transmits a command from the user to the external device, that is, the engine control device 16 or the door lock device 18 via the output unit 34, and the engine control device 16 or the door lock device. 18 allows the user's instructions to be executed.

The portable device control unit 42 receives the authentication request signal via the transmission / reception antenna 44 and the transmission / reception unit 46, and transmits a response signal as a response to the authentication request signal. An identification number unique to each portable device 14 to be included in the response signal is stored in the portable device memory 48.

  The portable device button 50 is a button for instructing the door lock device 18 to unlock or lock the door when the user is away from the vehicle 10. For example, when the portable device button 50 is pressed, the portable device 14 transmits a command signal including an identification number, and the in-vehicle unit 12 receives the command signal. And the vehicle equipment control part 30 will permit execution of a command to the door lock apparatus 18, if authentication of the identification number contained in a command signal is successful.

[Priority data]
Here, since the vehicle with a keyless authentication system has a plurality of portable devices 14, the in-vehicle unit 12 performs communication for authentication with the portable device 14 one by one in accordance with a predetermined order. Therefore, in this embodiment, in-vehicle priority small table (hereinafter also referred to as in-vehicle small table) and out-vehicle small table priority small table (hereinafter referred to as out-of-vehicle use) according to the type of command executed by the user. Is also stored in the in-vehicle device memory 36.

In the in-vehicle small table and the out-of-vehicle small table, the priority order of the portable device 14 when performing communication is respectively defined, and the in-vehicle device control unit 30 stores the stored in-vehicle small table and in-vehicle small table. According to the type of reading and command, communication is sequentially performed with the portable device 14 according to the small table for the vehicle or the small table for the vehicle.
In addition, the in-vehicle device control unit 30 can change and store (update) the stored in-vehicle small table and the in-vehicle small table in a predetermined case.

Specifically, when the in-vehicle device control unit 30 receives a door unlock command via the door unlock request button 28 and succeeds in authenticating the mobile device 14, the priority order of the mobile device 14 that has succeeded in authentication is given. Update the small external table so that it is the highest.
On the other hand, when the in-vehicle device control unit 30 receives an instruction to start the engine via the engine start request button 26 and succeeds in the authentication of the portable device 14, the priority order of the portable device 14 that has succeeded in authentication becomes the highest. Update the in-car small table.

  The in-vehicle device memory 36 stores the in-vehicle small table and the out-vehicle small table, so that the information on the position of the portable device 14 indicates whether the portable device 14 that has been successfully authenticated is in the vehicle or outside the vehicle. It can be said that the priority order is stored.

[Main program]
Hereinafter, with reference to FIG. 2, the main program which the vehicle equipment control part 30 mentioned above performs is demonstrated.
When the main program is executed, the vehicle exterior small table and the vehicle interior small table are read as initial settings, and the repetition number n is set to 1 (step S10). Then, it is determined whether or not a command has been input via the door unlock request button 28 and the engine start request button 26 (step S12).

  When the door unlocking command is input, the in-vehicle unit 12 transmits an authentication request signal to the portable device 14 having the priority order corresponding to the repetition number n in the on-vehicle small table (step S20). When step S20 is performed for the first time, since the repetition number n is 1, an authentication request signal is transmitted to the portable device 14 with the first priority in the small outside table.

  After step S20 is performed, it is determined whether or not the authentication is successful (step S22). In step S22, if the portable device 14 with the first priority is within the range in which the authentication request signal can be received, the authentication is successful. That is, the portable device 14 with the first priority order transmits a response signal, and the in-vehicle unit 12 receives this response signal and performs authentication, and authentication is successful. On the other hand, if the portable device 14 with the first priority is not within the range in which the authentication request signal can be received, the authentication fails. That is, the portable device 14 with the first priority does not transmit a response signal, and the in-vehicle unit 12 cannot perform authentication.

  When the authentication fails, that is, when a predetermined response waiting time elapses without receiving a response signal, the repetition number n is incremented by 1 (step S24). The repetition number n after the increment is compared with the total number N of the portable devices 14 (step S26). If the repetition number n does not exceed the total number N, step S20 is executed again. That is, until authentication is successful, communication for authentication with the portable device 14 is performed one by one in accordance with the priority order of the external small table.

If the authentication is successful in step S22, the in-vehicle device 20 permits the door lock device 18 to unlock the door (step S28), and as a result, the door is unlocked.
Then, after step S28, the priority order in the small table for the outside of the portable device 14 that has been successfully authenticated is updated to the first (step S30). For example, when the authentication of the portable device 14 with the second priority or lower is successful, the priority of the portable device 14 that has succeeded in the authentication is set to the first, and the priority of the portable device 14 that has been the first until then is the priority. The rank is set to No.2. In addition, when the authentication of the portable device 14 with the first priority is successful, there is no change in the priority in the small outside table.

  On the other hand, when an engine start command is input in step S12, the in-vehicle unit 12 transmits an authentication request signal to the portable device 14 having the priority order corresponding to the repetition number n in the in-vehicle small table (step S40). ). When step S40 is performed for the first time, since the repetition number n is 1, an authentication request signal is transmitted to the portable device 14 with the first priority in the small outside table.

  After step S40 is performed, it is determined whether or not the authentication is successful (step S42). In step S42, if the portable device 14 with the first priority is within the range in which the authentication request signal can be received, i.e., in the vicinity of the driver's seat in the passenger compartment, the authentication is successful. That is, the portable device 14 with the first priority order transmits a response signal, and the in-vehicle unit 12 receives this response signal and performs authentication, and authentication is successful. On the other hand, if the mobile device 14 with the first priority is not near the driver's seat in the passenger compartment, the authentication fails. That is, the portable device 14 with the first priority does not transmit a response signal, and the in-vehicle unit 12 cannot perform authentication.

  When the authentication fails, that is, when a predetermined response waiting time elapses without receiving a response signal, the repetition number n is incremented by 1 (step S44). The repetition number n after the increment is compared with the total number N of the portable devices 14 (step S46). If the repetition number n does not exceed the total number N, step S40 is executed again. That is, until the authentication is successful, communication for authentication with the portable device 14 is performed one by one in accordance with the priority order of the in-vehicle small table.

If the authentication is successful in step S42, the in-vehicle device 20 permits the engine control device 16 to start the engine (step S48) and turns on the engine start switch.
Then, after step S48, the priority order in the in-vehicle small table of the portable device 14 that has been successfully authenticated is updated to No. 1 (step S50). For example, when the authentication of the portable device 14 with the second priority or lower is successful, the priority of the portable device 14 that has succeeded in the authentication is set to the first, and the priority of the portable device 14 that has been the first until then is the priority. The rank is set to No.2. In addition, when the authentication of the portable device 14 with the first priority is successful, there is no change in the priority in the small outside table.

FIG. 3 illustrates the operation of the vehicle with the keyless authentication system of the first embodiment described above in time series.
In this example, among the four registered portable devices A to D, Mr. X possesses the portable device A and Mr. Y possesses the portable device B. When Mr. Y operates the door unlocking request button 28, the in-vehicle unit 12 first transmits an authentication request signal to the portable device A having the first priority according to the priority order defined in the small outside table. However, since Mr. X is not near the door of the vehicle 10, the authentication of the portable device A is not successful.

Next, the in-vehicle unit 12 transmits an authentication request signal to the portable device A having the second priority. Since Mr. Y is in the vicinity of the door of the vehicle 10, the authentication of the portable device B is successful and the door is unlocked. In addition, the priority order of the portable device B that has been successfully authenticated in the small outside table is updated to the first.
After unlocking the door, Mr. Y sits in the passenger seat, for example, and Mr. X sits in the driver's seat. When Mr. X operates the engine start request button 26, the in-vehicle unit 12 first transmits an authentication request signal to the portable device A having the first priority according to the priority order defined in the in-vehicle small table. At this time, since Mr. X is in the driver's seat in the vehicle, the authentication of the portable device A is successful. Therefore, Mr. X can turn on the engine start switch.

On the other hand, FIG. 4 illustrates the operation of a vehicle with a keyless authentication system of the prior art in time series.
In the prior art, a priority table (hereinafter also referred to as a conventional table) that does not take into account the position of the portable device was used. Therefore, after Mr. Y unlocked the door as in the example of FIG. The priority order of the portable device B in the conventional table is set to the first. When Mr. X operates the engine start request button 26, the in-vehicle unit 12 transmits an authentication request signal to the portable device B according to the priority order defined in the conventional table.

  At this time, Mr. Y is in the passenger seat, so the portable device B is not in the vicinity of the driver seat and authentication fails. Therefore, next, the in-vehicle unit 12 transmits an authentication request signal to the portable device A having the second priority, and the authentication is successful because the portable device A is in the vicinity of the driver's seat. Therefore, after authentication fails once, Mr. X can turn on the engine start switch.

  As described above, according to the vehicle with the keyless authentication system of the first embodiment, the vehicle unit 12 includes a plurality of portable devices 14 because the priority order is defined according to the information related to the position of the portable device 14.

As a result, according to the vehicle with the keyless authentication system, the authentication success rate is improved and the authentication speed is increased.

  Further, in the vehicle with the keyless authentication system of the first embodiment, the in-vehicle unit 12 uses a plurality of small tables, that is, a small table for in-vehicle use and a small table for external use for each position information, and finally authenticates in each small table. By setting the priority of the portable device 14 that has succeeded in the highest order, even if a plurality of portable devices 14 are registered, communication with the holder's portable device 14 is performed accurately first. As a result, according to the vehicle with the keyless authentication system, the authentication success rate is improved and the authentication speed is increased.

  Furthermore, in the vehicle with the keyless authentication system of the first embodiment, the information on the position of the portable device 14 is information indicating whether the portable device 14 that has been successfully authenticated is in the vehicle or outside the vehicle. Even if a plurality of portable devices 14 are registered, communication is accurately performed first with respect to the portable device 14 of the holder who intends to perform a predetermined action. As a result, according to the vehicle with the keyless authentication system, the authentication success rate is improved and the authentication speed is increased.

  Furthermore, in the vehicle with the keyless authentication system of the first embodiment, the in-vehicle unit 12 is used for authentication with the portable device 14 when one of the door unlock request button 28 and the engine start request button 26 is operated. Even if the communication is started, the communication with the holder's portable device 14 is performed accurately first. As a result, according to the vehicle with the keyless authentication system, the authentication success rate is improved and the authentication speed is increased.

The present invention is not limited to the first embodiment described above, and various modifications are possible.
For example, in the first embodiment, the in-vehicle small table and the small external table are stored in the in-vehicle device memory 36, but the small internal table and the small external table are electronic information, and two small tables are not necessarily included. It doesn't have to exist. In short, it is sufficient that the in-vehicle unit 12 has priority data as map data that defines the priority according to the position of the portable device 14, and the format of the priority data is not particularly limited. When viewed from the entire priority order data, the in-vehicle small table and the out-vehicle small table can be regarded as one data element group constituting the priority data.

  In the first embodiment, by limiting the communicable area of the transmission antenna 22, when the portable device 14 is near the door outside the vehicle and when the portable device 14 is near the driver's seat in the vehicle, the in-vehicle unit 12 And the portable device 14 can communicate with each other. However, the in-vehicle unit 12 may detect the absolute position of the portable device 14 and update the priority table according to the detected position. Good. That is, the information regarding the position of the portable device 14 may be information on a rough location or range of the portable device 14 or more detailed location information. And the acquisition method of the information regarding a position is not specifically limited.

  In the first embodiment, the in-vehicle unit 12 starts communication by operating the door unlock request button 28 and the engine start request button 26 as a trigger. However, the in-vehicle unit 12 communicates regularly or irregularly. May start. That is, the in-vehicle unit 12 may start communication only when the holder of the portable device 14 approaches the door or only when the holder of the portable device 14 is in the driver's seat in the vehicle.

In such a case, the door unlock request button 28 and the engine start request button 26 are not necessarily required. For example, a table update routine as shown in FIG. 5 may be executed regularly or irregularly.
In the table update routine of FIG. 5, the position of the portable device 14 is executed regularly or irregularly (step S70). Then, the result of step S70 is determined (step S72), and if the portable device 14 is detected in the vicinity of the door outside the vehicle, the priority order of the portable device 14 that has been successfully authenticated is set to the highest rank in the small outside table. (Step S74). On the other hand, if the portable device 14 is detected in the vicinity of the driver's seat in the vehicle, the priority of the portable device 14 that has been successfully authenticated is set to the highest in the small table for the vehicle (step S76).
