Description

  The present invention relates to a vehicle user authentication system.

  Conventionally, user information (such as a user ID) is registered in advance in a center mainly composed of servers, and user authentication (vehicles) is performed based on a user ID transmitted from the in-vehicle device (a user ID input by the user to the in-vehicle device). Alternatively, a system for performing association between an in-vehicle device and a user is known (for example, Patent Document 1).

JP 2004-248042 A

  However, in the system as described above, since the user needs to input user information such as a user ID registered in the center to the in-vehicle device and receive user authentication, the user information may be notified in advance. Many. Therefore, the following problems may occur.

  For example, when handing over a document describing user information at a dealer to a user who purchased a vehicle, depending on the country, it may be assumed that the user likes the vehicle that he / she took a test ride with, and then pays the credit at a later date. For this reason, it may be difficult to provide an opportunity to hand over the document. Even if there is an opportunity to hand over the document, there is a possibility that the dealer's employee may forget the task of handing over the document to the user.

  In addition, when user information is notified in advance including handing over a document, the user may not be able to confirm the user information due to loss of the document.

  Then, in view of the said subject, it aims at providing the user authentication system for vehicles in which a user can receive the authentication with respect to a vehicle, without notifying user information beforehand.

In order to achieve the above object, in one embodiment of the present invention,

And a center that performs user authentication for the vehicle based on first user information (such as a user ID and an initial password) that is associated with the vehicle and defined in advance. The in-vehicle device of the vehicle user authentication system is stored in an in-vehicle storage unit that stores in advance second user information (such as a user ID and an initial password) having the same content as the first user information, and an in-vehicle storage unit. An output processing unit that outputs the second user information as light or sound using a light emitting device or an acoustic device mounted on the vehicle. In addition, the mobile terminal of the vehicle user authentication system acquires light or sound output from the light emitting device or the acoustic device of the in-vehicle device, and recognizes the second user information and the second recognized by the recognition unit.

It is a flowchart which shows an example of a process of a portable terminal (a recognition part, a transmission process part) roughly. It is a flowchart which shows an example of a process of a center (authentication part) roughly.

  Hereinafter, embodiments for carrying out the invention will be described with reference to the drawings.

  FIG. 1 is a schematic block diagram showing an example of the configuration of a vehicle user authentication system (hereinafter simply referred to as “user authentication system”) 1 according to the present embodiment. The user authentication system 1 is provided on the vehicle 2 mounted on the vehicle 2, the mobile terminal 3, and the vehicle 2, and is mounted on the vehicle 2, the mobile terminal 3, and the wireless communication network 5 (for example, a mobile phone network). To user information (information registered in advance in the center 4 including a user ID, an initial password, etc .; hereinafter referred to as “first user information”). And a center 4 that performs user authentication for the vehicle 2 (linkage between the vehicle 2 and the user). When the user authentication by the center 4 is successful, the user uses the user ID and password (initial password or password changed by the user) to request the center 4 to remotely control the vehicle 2 from the portable terminal 3 or another terminal ( Remote control request) can be performed. Then, the center 4 performs remote control of the vehicle 2 in response to the remote control request (transmits a remote control command to the vehicle 2).

  The remote control of the vehicle 2 that can be requested from the user to the center 4 is, for example, locking / unlocking the vehicle 2, activation of an air conditioner mounted on the vehicle 2 (pre-air conditioning), and the like.

  The in-vehicle device 21 includes a DCM (Data Communication Module) 211, an ECU (Electrical Control Unit) 212, a notification unit 213, and an output unit 214.

  The DCM 211 is a communication device that performs two-way data communication with the center 4 via the wireless communication network 5 such as a mobile phone network. The DCM 211 is communicably connected to the ECU 212 via a one-to-one communication line or the like.

  The ECU 212 is an electronic control unit that executes main control processing in the in-vehicle device 21. The ECU 212 includes, for example, a microcomputer (an example of an output processing unit) and the like, and can execute various control processes described later by executing various programs stored in the ROM on the CPU. ECU 212 includes an internal memory (an example of an in-vehicle storage unit).

  The ECU 212 operates in either “initial registration mode” or “normal mode”. The “initial registration mode” is an operation mode for performing the above-described user authentication. On the other hand, the normal mode is a state in which user authentication for the vehicle 2 is completed, that is, in a state where the user and the vehicle 2 are linked. This is an operation mode, specifically, an operation mode for executing a control process based on a remote control command from the center 4. When the vehicle 2 is shipped from the factory, the operation mode of the ECU 212 is, of course, the initial registration mode. Is set to

  When the ECU 212 is in the initial registration mode, the ECU 212 is at a predetermined timing (for example, a timing after completion of the initial processing after the ignition (IG-ON) of the vehicle, a timing when a predetermined operation is performed on the in-vehicle device 21), or the like. User information (information including a user ID and an initial password having the same contents as the first user information registered in advance in the center 4, hereinafter referred to as “second user information”) is output via the output unit 214. Execute the process. Hereinafter, the flow of such processing will be described with reference to FIG.

  FIG. 2 is a flowchart schematically showing an example of processing by the in-vehicle device 21 (ECU 212).

  In step S <b> 102, the ECU 212 performs a notification (notification that the second user information is output toward the mobile terminal 3) that prompts the mobile terminal 3 to acquire the second user information via the notification unit 213. . For example, the notification unit 213 is a speaker provided in the vehicle interior, and the ECU 212 outputs voice guidance from the speaker. In addition, for example, the notification unit 213 is a display unit in the meter, and the ECU 212 displays a content indicating that the second user information is output to the display unit and a wording that prompts the acquisition of the second user information. Let

  In step S104, the ECU 212 executes a process of outputting the second user information via the output unit 214 in order to cause the mobile terminal 3 to acquire the second user information. In the internal memory of the ECU 212, a user ID and a plurality of initial registration passwords are stored in advance at the time of factory shipment, and one of the user ID and the plurality of initial registration passwords is output as second user information. Is done.

  Note that the user ID and the plurality of initial registration passwords (second user information) stored at the time of factory shipment are generated by a predetermined algorithm with respect to the VIN (Vehicle Identification Number) information of the vehicle 2. Further, the second user information may be stored in advance in a memory external to the ECU 212 (for example, the internal memory of the DCM 211), and the ECU 212 may acquire the second user information from the external memory. Further, the second user information may be in a form generated by the ECU 212 with a similar algorithm instead of being stored in advance in the internal memory of the ECU 212 at the time of factory shipment. Further, the first user information registered in advance in the center 4 (stored in advance in the center storage unit 42 to be described later) is generated by the same algorithm with respect to the VIN information of the vehicle 2. The first user information and the second user information have the same content.

  For example, the output unit 214 is a light-emitting device (specifically, an LED lamp for an emergency call indicator) provided in the passenger compartment. In such a case, the ECU 212 uses the encoded second user information (code information) as a predetermined blink pattern (bit string data using lighting / flashing, etc.) and outputs the second user information (code information). 214 (light emitting device) repeatedly (predetermined number of times).

  The emergency call indicator is an indicator indicating that an emergency call is being made, and the LED lamp blinks in a predetermined pattern. In addition, an emergency call is made through the DCM 211 in the event of an emergency of the vehicle 2 (for example, when the vehicle 2 collides with an obstacle, or when the user presses the emergency call button due to a sudden change in his / her physical condition). (Such as the center 4 or help net center).

  For example, the output unit 214 is an acoustic device (speaker) provided in the vehicle interior. In this case, for example, the ECU 212 repeatedly outputs (predetermined number of times) the second user information (code information) from the output unit 214 as bit string data (sound data) using the pitch of the sound.

  Further, for example, the output unit 214 is a communication module based on a communication standard such as Wi-Fi or Bluetooth (both are registered trademarks). The ECU 212 outputs second user information via the output unit 214 (communication module) based on a communication standard such as Wi-Fi or Bluetooth (transmits the second user information to the mobile terminal 3).

  Returning to FIG. 1, when in the normal mode, the ECU 212 executes control processing according to the remote operation command transmitted from the center 4 as described above. For example, when the remote operation command from the center 4 is a command to lock the door of the vehicle 2, the ECU 212 transmits a locking request to a body ECU (not shown). As a result, the body ECU operates the door lock motor to lock the door. When the remote operation command transmitted from the center 4 is a command for starting the air conditioner, the ECU 212 IG-ONs the vehicle 2 and transmits an air conditioning start request to the air conditioner ECU (not shown) to be registered in advance. The air conditioner is operated in the set state or the set state included in the command.

  The mobile terminal 3 is an information processing terminal that can be carried by a user, and is an information processing terminal that can perform data communication with the center 4 via a wireless communication network 5 such as a mobile phone network. It is a mobile phone owned by the user. A predetermined application downloaded via the Internet is installed in the mobile terminal 3 according to a predetermined operation. The portable terminal 3 includes a recognition unit 31 and a transmission processing unit 32 as functional units realized by executing such an application on the OS of the portable terminal 3. Hereinafter, with reference to FIG. 3, the processing operation by the portable terminal 3 (recognition unit 31, transmission processing unit 32) will be described.

  The mobile terminal 3 includes a camera (not shown) and a microphone (not shown). The application is provided by a manufacturer that manufactures the vehicle 2, and the user can download the application through, for example, an application site for smartphones or an Internet site designated by the manufacturer.

  FIG. 3 is a schematic flowchart illustrating an example of processing performed by the mobile terminal 3 (the recognition unit 31 and the transmission processing unit 32). FIG. 3A is a flowchart in the case where the output unit 214 of the in-vehicle device 21 is the above-described light emitting device (LED lamp of an emergency notification indicator), and FIG. It is a flowchart in the case of the audio equipment (speaker) mentioned above. Such a flowchart is executed in response to a predetermined operation on the mobile terminal 3 by the user.

  Note that the flowcharts shown in FIGS. 3A and 3B represent a typical flow, and supplementary explanation will be given as appropriate for the branch processing (determination processing) and the like that are actually executed.

  First, FIG. 3A will be described.

  In step S202, the recognition unit 31 acquires a captured image (camera image) of the camera of the mobile terminal 3.

  In step S204, the recognition unit 31 executes processing for recognizing the blinking pattern described above from the acquired camera image.

  If the blinking pattern cannot be recognized because the camera of the mobile terminal 3 is not properly directed to the light emitting device, the recognition unit 31 may end the processing according to this flowchart, or may be performed again with the camera. A notification that prompts the user to capture the blinking pattern may be displayed on the display unit of the mobile terminal 3, and the processes in steps S202 and S204 may be repeated.

  In step S206, the recognizing unit 31 executes a process of restoring the blinking pattern as second user information (such as a user ID and an initial password). That is, the recognition unit 31 performs the reverse process of the process in which the ECU 212 of the in-vehicle device 21 converts the second user information (code information) into the blinking pattern, and acquires the second user information.

  In step S208, the transmission processing unit 32 transmits the acquired second user information to the center 4 and performs processing for requesting user authentication to the center 4 (user authentication request).

  In step S210, when the user authentication in the center 4 is successful (the vehicle 2 and the user are linked), the transmission processing unit 32 performs initial registration in the center 4 according to the user's operation on the mobile terminal 3. Processing to be executed is performed (initial registration processing). The transmission processing unit 32 displays, for example, a screen for selecting a service to be used on the display unit of the mobile terminal 3 and a screen on which the center 4 agrees to collect information from the vehicle 2 (various sensors, actuator detection signals, control signals, etc.). Display processing is performed to prompt the user to perform initial registration. Then, the transmission processing unit 32 performs processing for transmitting the content (initial registration information) input by the user's operation on the mobile terminal 3 to the center 4.

  Subsequently, FIG. 3B will be described.

  In step S <b> 302, the recognizing unit 31 performs a process of acquiring sound (microphone sound) collected by the microphone of the mobile terminal 3.

  In step S304, the recognizing unit 31 executes a process of recognizing a sound corresponding to the bit string data (sound data) using the above-described pitch or length of the sound from the acquired microphone sound (sound recognition).

  If sound recognition cannot be performed because the microphone of the mobile terminal 3 is covered with a hand or the like, the recognition unit 31 may end the process according to this flowchart, or prompt the microphone to collect sound again. The notification may be displayed on the display unit of the mobile terminal 3, and the processes in steps S302 and S304 may be repeated.

  In step S306, the recognition unit 31 executes a process of restoring the recognized sound (sound data) as second user information (such as a user ID and an initial password). That is, the recognition unit 31 performs the reverse process of the process in which the ECU 212 of the in-vehicle device 21 converts the second user information into the sound data, and acquires the second user information.

  Steps S308 and S310 are the same processes as steps S208 and S210, respectively, and thus description thereof is omitted.

  When the output unit 214 is the communication module described above, the second user transmitted from the output unit 214 (communication module) with a compliant communication standard instead of the processing of steps S202 to S206 or steps S302 to S306. What is necessary is just to perform the process which receives information. However, the mobile terminal 3 needs to be set in a state where communication by Wi-Fi, Bluetooth or the like is possible. When the communication standard is Wi-Fi, the mobile terminal 3 needs to be connected to the Wi-Fi network formed by the output unit 214.

  Returning to FIG. 1, the center 4 is configured with a server or the like as the center, and includes a transmission / reception unit 41, a center storage unit 42, an authentication unit 43 and the like.

  The transmission / reception unit 41 receives data transmitted from the in-vehicle device 21 (DCM 211) and the portable terminal 3 through the wireless communication network 5 such as a cellular phone network. The transmission / reception unit 41 transmits data to the in-vehicle device 21 (DCM 211) and the mobile terminal 3 through the wireless communication network 5.

  The center storage unit 42 stores in advance first user information (information including a user ID and an initial password) associated with the vehicle 2 (specifically, VIN information of the vehicle 2). As described above, the first user information stored in the center storage unit 42 is stored in the ECU 212 (internal memory) of the vehicle 2 at the time of factory shipment with respect to the VIN information of the vehicle 2 that is defined in advance. It is generated by the same algorithm as when user information is generated. Therefore, as described above, the first user information registered in the center 4 and the second user information stored in the ECU 212 (internal memory) have the same contents.

  Based on the first user information stored in advance in the center storage unit 42 and the second user information transmitted from the mobile terminal 3, the authentication unit 43 performs user authentication for the vehicle 2 (correlation between the vehicle 2 and the user). )I do. Hereinafter, the processing in the authentication unit 43 will be described with reference to FIG.

  FIG. 4 is a flowchart schematically showing an example of processing of the center 4 (authentication unit 43). This flowchart is executed when the transmission / reception unit 41 receives the second user information from the portable terminal 3.

  Note that the flowchart shown in FIG. 4 shows a typical flow, and supplementary explanation will be given as appropriate regarding the branch processing (determination processing) and the like actually executed.

  In step S <b> 402, the authentication unit 43 acquires second user information received by the transmission / reception unit 41 from the mobile terminal 3.

  In step S404, the authentication unit 43 receives the second user information (user ID and initial password) received by the transmission / reception unit 41 from the mobile terminal 3, and the first user information (user ID and user ID) stored in the center storage unit 42. The user authentication is performed by comparing with the initial password. If the first user information and the second user information match, the authentication unit 43 authenticates the user's legitimacy for the vehicle 2 (authentication success), and otherwise does not authenticate (authentication failure). When the authentication is successful, the authentication unit 43 transmits a notification that the authentication is successful to the mobile terminal 3 through the transmission / reception unit 41.

  If authentication fails, the authentication unit 43 may end the processing according to this flowchart, or request the mobile terminal 3 to retransmit the second user information via the transmission / reception unit 41. May be.

  In step S406, the authentication unit 43 performs initial registration based on the initial registration information received from the portable terminal 3 by the transmission / reception unit 41.

  Note that, for example, when the application is terminated without performing the initial registration operation on the mobile terminal 3, the transmission / reception unit 41 does not receive the initial registration information even after a predetermined period elapses. The process of step S408 is executed without executing the process.

  In step S408, the authentication unit 43 transmits a user information output stop command and a normal mode transition command to the in-vehicle device 21 (DCM 211), and ends the current process. The user information output stop command is a command to stop the process in which the ECU 212 described above outputs the second user information from the output unit 214. The normal mode transition command is a command for shifting the operation mode of the ECU 212 to the normal mode. Based on the user information output stop command received by the DCM 211, the ECU 212 prevents the process of outputting the second user information from the output unit 214 described above. This avoids a situation in which a third party receives user authentication using the mobile terminal 3 even though user authentication has already been performed and the user and the vehicle 2 have been linked. Can do. Further, based on the normal mode transition command received by the DCM 211, the ECU 212 sets the operation mode to the normal mode.

  When the user of the vehicle 2 changes, for example, when a new user makes a request to the center 4 by means (phone, fax, e-mail, etc.) prescribed in advance, the authentication unit 43 of the center 4 passes through the transmission / reception unit 41. The initial registration mode transition command is transmitted to the in-vehicle device 21 (DCM 211). Thereby, based on the initial registration mode transition command received by the DCM 211, the ECU 212 sets the operation mode to the initial registration mode, so that a new user can receive user authentication in the center 4 according to the above-described content.

  As described above, the user authentication system 1 according to the present embodiment is provided on the vehicle 2 mounted on the vehicle 2, the mobile terminal 3, and the vehicle 2, and can communicate with the vehicle-mounted device 21 and the mobile terminal 3. And a center 4 that performs user authentication for the vehicle 2 based on first user information that is defined in advance in association with the vehicle 2. Further, the in-vehicle device 21 of the user authentication system 1 stores, in the vehicle, an internal memory that stores in advance second user information having the same content as the first user information, and second user information stored in the internal memory. An ECU 212 including a microcomputer or the like that is output from an output unit 214 (light emitting device, acoustic device, or communication module) to be mounted is provided. In addition, the mobile terminal 3 of the user authentication system 1 acquires second user information (corresponding to light, sound, or communication data) output from the output unit 214 of the in-vehicle device 21, and acquires the second user information. A recognition unit 31 that recognizes and a transmission processing unit 32 that transmits second user information recognized by the recognition unit 31 to the center 4 are provided. The center 4 of the user authentication system 1 includes a center storage unit 42 that stores first user information in advance, and a transmission / reception unit 41 that receives second user information transmitted from the transmission processing unit 32 of the mobile terminal 3. An authentication unit 43 that performs user authentication based on the first user information stored in the center storage unit 42 and the second user information received by the transmission / reception unit 41 is provided. Therefore, when the user brings the mobile terminal 3 (for example, a mobile phone owned by the user) close to the output unit 214 (light emitting device, acoustic device, or communication module) of the in-vehicle device 21, the recognition unit 31 of the mobile terminal 3 Sound, light, or communication data output from the output unit 214 is acquired to recognize the second user information, and the transmission processing unit 32 of the portable terminal 3 transmits the second user information to the center 4. The transmission / reception unit 41 of the center 4 receives the second user information from the transmission processing unit 32 of the mobile terminal 3, and the authentication unit 43 of the center 4 stores the first user information stored in advance in the center storage unit 42. And user authentication based on the second user information received by the transmission / reception unit 41. Therefore, the user can receive authentication for the vehicle 2 without notifying the user of the vehicle 2 in advance of user information.

  Further, when utilizing a light emitting device or an acoustic device mounted on the vehicle 2 as the output unit 214, it is not necessary to provide a dedicated device for transmitting the second user information from the in-vehicle device 21 to the mobile terminal 3, An increase in cost for performing user authentication can be suppressed.

  As mentioned above, although the form for implementing this invention was explained in full detail, this invention is not limited to this specific embodiment, In the range of the summary of this invention described in the claim, various Can be modified or changed.

  For example, in the above-described embodiment, the mobile terminal 3 directly acquires light, sound, communication data, or the like corresponding to the second user information output from the output unit 214, but the present invention is not limited to this mode. For example, the second user information is displayed on the display unit in the meter as the output unit 214, and the user recognizes the user ID and the initial password displayed on the display unit, and inputs the operation to the portable terminal 3. May be. Even in such a case, the user can receive authentication for the vehicle 2 without notifying the user of the vehicle 2 in advance of user information.
