The present invention relates to a user authentication device.

  2. Description of the Related Art Conventionally, a vehicular user authentication device that is mounted on a vehicle and authenticates whether or not the vehicle driver is an authorized user is known (see, for example, Patent Document 1).

Patent Document 1 discloses a PIN code spoken by a passenger for the purpose of enabling user authentication in a hands-free manner when an automobile passenger uses a mobile phone network to make a payment. An apparatus for recognizing by voice recognition and collating with a pre-stored personal identification number to confirm the user is disclosed.
JP 2005-31711 A

  Certainly, the conventional device described in the above-mentioned Patent Document 1 enables a hands-free password input by adopting a voice recognition technology.

  However, even with such an input method, the user is reminded while driving, 1) the required password number, and 2) the voice recognition device can correctly recognize the password number. A series of actions are required to speak slowly and clearly.

  In other words, even if manual operation is no longer necessary due to voice input, every time an action that requires user authentication during driving operation (payment settlement in this case) is performed, an operation other than driving operation is requested from the driver. In that respect, it can be said that the user authentication method in the conventional device described in Patent Document 1 can also reduce the driver's attention to driving operation.

  The user authentication method in the conventional device described in Patent Document 1 is not necessarily highly user-friendly because it requires the driver to speak carefully so that voice recognition is correctly performed. Further, it is difficult to say that the vehicle driving safety is sufficient in that the driver's attention is directed to uttering the password.

  The present invention is to solve such problems, and a main object of the present invention is to provide a vehicular user authentication device that appropriately achieves both driving safety and user convenience.

  One aspect of the present invention for achieving the above object is a vehicle user authentication device that is mounted on a vehicle and authenticates whether or not the vehicle driver is the authorized user himself / herself, and a user authentication result at the time of boarding the vehicle Is a vehicle user authentication device that is effective until the vehicle is alighted.

  In the above aspect, when the vehicle is in a vehicle, for example, a) a period from when the vehicle propulsion power source is started until the vehicle starts to travel, and b) after the driver has been seated in the driver's seat, the vehicle travels. A period until the vehicle starts, or c) a period from when the driver's seat door is locked in a state where the driver is seated on the driver's seat until the vehicle starts to travel. When the vehicle gets off, for example, a) When the operation of the vehicle propulsion power source is stopped, b) when the driver's seat door is unlocked while the driver is seated in the driver's seat, or c) when the driver leaves the driver's seat.

  Moreover, in the said one aspect | mode, when user authentication is performed by collation of a PIN code, the PIN code input at the time of boarding a vehicle is hold | maintained until a vehicle alights.

  According to the above aspect, the user authentication result at the time of getting on the vehicle is not valid only for one operation, but is valid until the vehicle gets off, so that the vehicle driver is the authorized user himself when getting on the vehicle. When authenticated, it is possible to allow the operation of the in-vehicle device that requires user authentication until the vehicle gets off without any operation for user authentication, and the driver can perform any operation for user authentication while driving the vehicle. It is not required, and the security is ensured by user authentication, and the improvement of user convenience and the improvement of vehicle running safety by not requiring any user operation / operation during driving are properly achieved. Can do.

  In the above aspect, in the case of user authentication based on password verification, a dedicated pushbutton for inputting the password or shared with another in-vehicle system such as an air conditioner may be provided. A touch panel type button displayed on a display combined with another in-vehicle system such as a navigation system may be provided, or a voice input device (microphone) and a voice recognition processing unit may be provided, or Any combination of these may be used. When the personal identification number is input by voice input, it is preferable that execution of user authentication is allowed only when all doors and windows of the host vehicle are closed.

  Moreover, in the said one aspect | mode, for the user who does not want the user authentication result at the time of a vehicle boarding to be validated until the time of a vehicle alighting, according to the request | requirement from a user, the user authentication result at the time of boarding a vehicle It is preferable that the switch is made so as not to be effective until the vehicle gets off.

  ADVANTAGE OF THE INVENTION According to this invention, the user authentication apparatus for vehicles which can make driving | running | working safety and user convenience compatible appropriately can be provided.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the accompanying drawings.

  Hereinafter, a vehicle user authentication device according to an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a schematic configuration diagram of a vehicle user authentication device 100 according to the present embodiment.

  The vehicle user authentication device 100 includes a user input unit 101 for the driver of the own vehicle to input a password. The user input unit 101 may be a push button that is dedicated or used in combination with another in-vehicle system such as an air conditioner, or a touch panel displayed on a display that is dedicated or used in combination with another in-vehicle system such as a navigation system. It may be a button of a formula, or may be constituted by a voice input device (microphone) and a voice recognition processing unit, or any combination thereof.

  Three specific examples are shown in FIG. FIG. 2A shows an example of a case where a dedicated push button representing numbers 0 to 9 is provided at the bottom of the display panel. Further, the code number here is equivalent to the code number and need not be limited to numbers. For example, as shown in FIG. 2B, for example, a dedicated code representing alphabets A to J around the display panel. The user authentication may be completed (passed) when the push buttons are provided and are pressed in a regular order (for example, A → D → I → H → C) registered in advance. Furthermore, a temporary PIN code may be displayed on the display by using voice recognition processing, and an addition value or a subtraction value with the true PIN number may be input by voice to the user. In FIG. 2C, when the true password is “1250”, a temporary password “1234” is displayed, and the user authentication is completed when the user inputs “plus 16” by voice input (pass) ) Shows an example.

  In the following description, as an example, the user input unit 101 is configured to require the user to input a personal identification number, for example, as shown in FIG. It is assumed that the user authentication is completed when the registered regular password matches.

  Returning to FIG. The vehicular user authentication device 100 further includes a storage unit 102 that stores and holds a normal password in advance and temporarily stores and holds an authentication result. In the present embodiment, the storage unit 102 may be a storage medium of any format / type as long as it can be rewritten.

  The vehicle user authentication device 100 further includes a control unit 103 that comprehensively controls each component of the vehicle user authentication device 100. In the present embodiment, the control unit 103 is, for example, an ECU (Electronic Control Unit).

  In the present embodiment, the control unit 103 is configured to receive engine ON / OFF information and vehicle speed information. The vehicle speed is detected by, for example, a wheel speed sensor (not shown).

  In the vehicle user authentication device 100 having such a configuration, the control unit 103 has a user input unit only when the engine is started and the vehicle speed is still zero and the vehicle has not started running. It is configured to accept user input through 101.

  In other words, while the vehicle is running, user input for user authentication is not accepted, and user authentication cannot be performed.

  The vehicle-mounted device that requests user authentication for security reasons when starting the device or performing a predetermined device function performs user authentication processing on the vehicle user authentication device 100 and returns an authentication result when requesting user authentication. To ask.

  At normal time, the control unit 103 collates the personal identification number input through the user input unit 101 with a regular personal identification number stored in advance in the storage unit 102, and another in-vehicle device that has requested user authentication for the verification result. However, as will be described in detail later, in this embodiment, the authentication result of the user authentication performed when the vehicle is stopped when the vehicle gets on is stored and held as valid until the vehicle gets off. Therefore, when such a valid user authentication result is stored and held in the storage unit 102 when the user authentication is requested, the control unit 103 immediately performs the user authentication without performing the password verification process one by one. An authentication result of completion (authentication OK) is returned to the other in-vehicle device as the request source.

  Next, the flow of user authentication processing by the vehicle user authentication device 100 according to the present embodiment will be described in detail with reference to the flowchart of FIG.

  First, the control unit 103 waits for engine start (S301).

  When the engine is started (“YES” in S301), the control unit 103 determines whether the host vehicle is stopped, that is, whether the vehicle speed is zero (S302).

  When it is determined that the vehicle speed is greater than zero and the vehicle has already started running ("NO" in S302)), in this embodiment, the user authentication cannot be performed while the vehicle is running. It is determined that the user authentication method according to the present embodiment in which user authentication is completed during the stop is no longer available, and one routine of this flow is immediately terminated.

  On the other hand, when it is determined that the vehicle speed is zero and the vehicle is stopped (“YES” in S302), the control unit 103 then determines a password for user authentication from the user through the user input unit 101. Wait for input (S303).

  When the password is input from the user (“YES” in S303), the control unit 103 then collates the input password with the regular password stored in advance in the storage unit 102, It is determined whether or not the user who has input the personal identification number is a regular user (S304).

  When the personal identification number input by the user through the user input unit 101 and the regular personal identification number stored in advance in the storage unit 102 do not match, the control unit 103 determines that the user (driver) who has input the personal identification number is authorized. It is determined that the user is not a user (“NO” in S304), and one routine of this flow is immediately terminated.

  On the other hand, when the personal identification number input by the user through the user input unit 101 matches the regular personal identification number stored in the storage unit 102 in advance, the control unit 103 is the user (driver) who has input the personal identification number. Is determined to be a regular user (“YES” in S304), and the authentication result indicating that user authentication is completed (authentication OK) is temporarily stored in the storage unit 102 (S305).

  When the user authentication is completed in a stopped state before the vehicle starts to travel in this way, the user authentication is thereafter performed from an in-vehicle device that requires user authentication for starting or performing a predetermined function while the vehicle is traveling. Is requested (“YES” in S306), the control unit 103 replies to the other in-vehicle device that requests such user authentication that the user authentication is completed (authentication OK) ( S307).

  That is, since the user authentication is completed when the engine is started and the vehicle is stopped before the vehicle starts running, the authentication result at the time of boarding can be obtained even if the driver does not perform any operation / action while the vehicle is running. Since it is effectively used and user authentication is automatically completed (authentication OK), the driver can use an in-vehicle device or function that requires user authentication without depriving attention other than driving operation. .

  When such user authentication is requested, the user authentication is automatically completed based on the authentication result stored in the storage unit 102 without requiring the driver to perform any operation / operation such as input of a personal identification number. Is continued until the engine is stopped ("NO" in S308 and the process returns to S306).

  When the engine stops (“YES” in S308), the control unit 103 clears the user authentication result at the time of boarding temporarily stored in the storage unit 102 (S309).

  As described above, according to the present embodiment, once user authentication is completed at the time of starting the engine, the authentication result is effectively held until the engine is stopped next time, so user authentication is required during vehicle travel. When using the functions of an in-vehicle device, the driver does not need to perform any operation / operation for user authentication and is not deprived of attention. Vehicle driving safety is ensured by ensuring that the driver does not operate if user authentication is not completed as it is, and that the driver who is driving the vehicle is not deprived of attention to operations / operations other than driving operation. And user convenience can be appropriately achieved.

  In the above-described embodiment, as an example, user authentication is performed when the engine is started as an example when the vehicle gets on, and the user authentication result temporarily stored when the engine is stopped is cleared as an example when the vehicle gets off. However, the present invention is not limited to such an embodiment. For example, when the vehicle is in the vehicle, the vehicle travels during the period from when the driver is seated in the driver's seat until the vehicle starts running or after the driver's seat door is locked while the driver is seated in the driver's seat. It is also possible to accept the input of a personal identification number for user authentication during the period until the start of. Similarly, when the vehicle gets off, for example, when the driver's seat door is unlocked while the driver is seated in the driver's seat, or when the driver leaves the driver's seat, the data is temporarily stored. The user authentication result may be cleared.

  Further, in the above embodiment, for a user who does not want the user authentication result when the vehicle gets on the vehicle to be valid until the vehicle gets off, for example, a switch for turning off the operation of this function is added. If requested by the user, the user authentication result at the time of getting on the vehicle may be switched so as not to be valid until the vehicle gets off.

  The present invention can be used for a vehicle user authentication device. The power source type, fuel type, appearance design, weight, size, running performance, etc. of the vehicle to be mounted are all unquestioned.
