Description

  One aspect of the present invention relates to a vehicle antitheft device having a function of preventing theft of a vehicle by a third party by authenticating a driver of the vehicle.

  Conventionally, various techniques have been proposed as an apparatus for preventing theft of a vehicle. For example, Patent Document 1 discloses a technology in which an authentication system is mounted on a vehicle, and an operator (driver) of the vehicle is authenticated to determine whether or not the vehicle can be driven. In this technology, the face of the operator photographed by the in-vehicle camera is identified by comparison with the face of the registrant previously stored in the storage unit, and the door opening or engine start is permitted only for a specific limited operator. doing. In this case, since the owner of the vehicle is usually the operator (driver), the face image of the owner of the vehicle is registered in advance in the storage unit. Moreover, there are techniques as described in Patent Literature 2 to Patent Literature 4 as similar techniques.

  However, it is not limited to only the owner of the vehicle that can be the driver of the vehicle. For example, if the owner of the vehicle has a co-resident such as a family, these family members can also be drivers. In addition, there is also a case where a dealer's person drives between a home and a repair shop for vehicle maintenance such as car inspection. Furthermore, when traveling with a friend, there is also a case where this friend drives on behalf of the friend. In this respect, with regard to the family, it is conceivable to register the face image in the storage section in advance as a possible driver, but it is a reality that the face image is registered in advance with respect to the dealer and friends. It is not target. In addition, the task of registering in the storage unit the face images of all the potential drivers in the first place is complicated.

  In other words, the driver's authentication is performed using a face image registered in advance, and the driver can operate the vehicle by opening the door or starting the engine after the authentication is successful. It was difficult to cope with family shopping in the neighborhood and temporary driving of the vehicle by dealers and friends, as they were making a limited decision that they would not be allowed. Furthermore, under the situation where the face image can not be registered in the storage unit, even though the owner of the vehicle permits it, there has been a situation where the engine of the vehicle can not even be started.

  The present invention adopts the following means in order to solve the above problems.

In the following description, the main flow will be described first with reference to FIG. 3, and then the driver authentication process, which is a feature of the present embodiment, will be described with reference to FIG. 4.

<S400 to S420>
When the driver 2 of the vehicle 1 inserts a key into the vehicle 1 and makes it rotate, the key recognition device 80 detects this operation and notifies the antitheft control device 10 of the main flow of the vehicle antitheft processing. It is started (S400). First, the antitheft control device 10 activates each component of the vehicle antitheft device shown in FIG. Then, the antitheft control device 10 starts the engine by instructing the electronic control device 60 via the ECU-IF unit 16 (S410). Then, the antitheft control device 10 instructs the handle lock device 70 to lock (lock) the handle in a non-rotatable state (S420).

<S430 to S440>
Next, the antitheft control device 10 confirms whether the inserted key is legitimate or not by the key collating system such as the immobilizer (S430). If the key confirmation is successful (Y in S430), the antitheft control device 10 executes a driver authentication process (S440). The specific content of the driver authentication process will be described later with reference to FIG.

<S450 to S480>
As a result of the driver authentication process (S440), when the driver authentication is successful (Y in S450), the anti-theft control device 10 instructs the handle lock device 70 to make the handle rotatable (cancel the handle lock) ) (S460), the vehicle antitheft process is ended (S480).

<S470 to S480>
Here, if the key confirmation fails (N in S430) or if the driver authentication fails (N in S450), the antitheft control device 10 may control the electronic control device via the ECU-IF unit 16 Instructs 60 to shut down the engine. At this time, the electronic control unit 60 performs a process of stopping the engine according to the instruction, and the vehicle antitheft process is ended (S480).

<Driver authentication process (S440)>
Next, the process of the driver authentication process (S440) will be specifically described with reference to FIG.

<S100 to S110>
When the driver authentication process starts (S100), the antitheft control device 10 activates the scanner device 40 (S110). Then, the antitheft control device 10 controls the display control unit 13 and the car navigation IF unit 11 to urge the driver to cause the liquid crystal display device of the car navigation device 50 to read the driver's license by the scanner device 40 (see FIG. Display the image). It should be noted that the notification to the driver by the car navigation device 50 may output voice from the voice output device instead of or in addition to displaying an image on the liquid crystal display device.

<S120 to S130>
Next, the scanner device 40 reads and acquires the driver's face image from the driver's face image portion in the driver's license which the driver intends to read (S120). The face image acquired here is stored in the scanner image storage unit 22 via the antitheft control device 10. If the driver's license has not been read because the driver does not carry the driver's license (N in S130), the process proceeds to S260.

<S140>
If reading of the face image from the driver's license is successful (Y in S130), the anti-theft control device 10 controls the imaging device 30 to image the face of the person who got on the driver's seat of the vehicle 1 (S140). The imaging device 30 outputs, to the anti-theft control device 10, a face image of a person (driver) who got in the driver's seat that has been captured.

<S150 to S160>
Next, the antitheft control device 10 checks whether or not there is a face image registered in advance in the face image storage unit 21 (S150). When there is a face image registered in advance in the face image storage unit 21 (Y in S150), the anti-theft control device 10 is registered in the face image storage unit 21 other than the face image registered in advance. Check whether there is a latest registered image (S160). Here, the latest registered image is a face image of a person who has succeeded in authentication, which is stored in the face image storage unit 21 by the process (S280) described later, and authentication fails due to aging of the driver's face or the like. It is used to prevent that.

<S170 to S180>
When the latest registration image is stored in the face image storage unit 21 (Y in S160), the antitheft control device 10 controls the driver authentication unit 15, and the latest registration image and the driving input from the imaging device 30 The image is compared with the face image of the person (S170). The comparison of face images here is performed by the existing image processing technology. If the authentication by the driver authentication unit 15 is successful (Y in S180), the process proceeds to S270.

<S270 to S290>
When the driver's authentication is successful, the antitheft control device 10 transmits a driving permission instruction signal to the electronic control device 60 via the ECU-IF unit 16 (S270). In addition, the antitheft control device 10 updates the face image of the driver (the face image captured by the imaging device 30) which has succeeded in authentication by storing the face image in the face image storage unit 21 (S280). That is, the oldest face image among the face images of the same driver as the driver who succeeded in the authentication in this process is deleted, and the face image newly captured in this process is stored in the face image storage unit 21 The prevention control device 10 processes. Thereafter, the driver authentication process ends (S290).

<S190 to S200>
On the other hand, when the latest registration image is not stored in the face image storage unit 21 (N in S160), or when the authentication based on the latest registration image fails (N in S180), the antitheft control device 10 preliminarily Authentication based on the face image registered in the face image storage unit 21 is executed (S190). Specifically, the theft prevention control device 10 controls the driver authentication unit 15, and compares the pre-registered image stored in the face image storage unit 21 with the driver's face image input from the imaging device 30. I do. If the authentication is successful (Y in S200), the process proceeds to S270.

<S210 to S220>
If the face image storage unit 21 does not store the face image registered in advance in the first place (N in S150), or if the authentication based on the pre-registered image fails (N in S200), the antitheft control device 10 The authentication based on the face image of the driver's license read in the process of S120 is executed (S210). Specifically, the theft prevention control device 10 controls the driver authentication unit 15, and the driver's license face image stored in the scanner image storage unit 22 and the driver's face image input from the imaging device 30. Compare with. If the authentication is successful (Y in S220), the process proceeds to S270.

<S230 to S240>
When the authentication based on the face image of the driver's license fails (N in S220), the anti-theft control device 10 controls the imaging device 30 to capture the face of a person (accompanying person) who gets on the passenger seat of the vehicle 1 (S230). The imaging device 30 outputs the captured face image of the passenger to the antitheft control device 10. Then, the anti-theft control device 10 controls the driver authentication unit 15, and executes authentication based on the face image of the passenger by comparison with the face image registered in advance (S240). Here, authentication is performed based on whether the face image of the passenger matches any of the pre-registered image and the latest registered image stored in the face image storage unit 21 and the face image stored in the scanner image storage unit 22. Perform (S240). Note that this authentication does not necessarily have to be performed on all the face images stored in the face image storage unit 21 and the scanner image storage unit 22 of the external storage device 20, and authentication using any of the face images is performed. May be If the authentication is successful (Y in S250), the process proceeds to S270.

<S260>
When the authentication fails (S250), that is, when all the authentication fails, the antitheft control device 10 controls the display control unit 13 and the car navigation IF unit 11 to display the liquid crystal display of the car navigation device 50. Display a message to the effect that the operation is not permitted, such as “Operation not permitted”. At this time, voice is simultaneously output from the voice output unit of the car navigation device 50. After that, the driver authentication process is ended on the assumption that the authentication has failed (S290).

<Summary>
As described above, in the driver authentication process, (A) face image of driver or passenger, (B-1) face image indicated on driver's license, (B-2) face image storage unit 21 The face image as the latest registered image stored, or (B-3) the face image as the pre-registered image stored in the face image storage unit 21 is compared, and if any of the comparisons succeeds, the authentication succeeds. The process is to be done. As described above, in the vehicle antitheft device according to the present embodiment, the processing for putting the vehicle into the operable state is performed by the authentication of the driver or the passenger under several expanded conditions. This makes it possible to permit driving when it is estimated that the vehicle owner is allowed to drive under the same condition, thus eliminating the inconvenience caused by strictly authenticating the driver. can do.

  In the present embodiment, in particular, when the authentication based on the face image indicated by the driver's license is successful, the vehicle is in the drivable state, and thus the face image of the person permitted to drive the vehicle is not registered in advance. Even if the driver's license is presented, the vehicle can be made drivable. Further, since it is necessary to read the driver's license, it is possible to prevent the non-carrying of the driver's license.

  Further, in the present embodiment, even when the authentication based on the face image registered in advance is successful, the vehicle can be driven so that relatively flexible driver authentication can be performed.

  Further, in the present embodiment, the face image of the person who has succeeded in the authentication as the driver in the past is stored as the latest registered image, and the vehicle can be operated even when the authentication based on the latest registered image is successful. Therefore, even if the facial features change over time due to aging or the like, the authentication can be made easier to succeed.

  Further, in the present embodiment, even when the driver fails in authentication, if the passenger succeeds in authentication, it is processed as if authentication is successful, and therefore, more flexible authentication is possible. .
