[0030]
[Unlocking control of the first embodiment]
2 and 3 are flowcharts showing the unlock control of the first embodiment according to the present invention.
[0031]
In this first embodiment, in FIG. 1, the anti-theft performance is emphasized, and the system configuration is such that door unlocking is not permitted only by collation with the IC card 1, and the fingerprint authentication threshold value of the door unlocking fingerprint authentication device 5 is set to the door unlocking. The authentication control unit 6 is caused to function as a changing means that changes according to the collation status of the identification information by the IC card reader 2. As described above, the engine start IC card reader 11 and the engine start fingerprint authentication device 12 are not mounted.
[0032]
Specifically, when the user unlocks the door by using both verification by the IC card 1 and fingerprint authentication, the fingerprint authentication device 5 for unlocking the door is compared with the case of unlocking the door only by fingerprint authentication. Set the authentication threshold by.
[0033]
According to the above control, the threshold value for authentication by the fingerprint authentication device 5 for unlocking the door can be set to an optimum value that can maintain both security and improve the accuracy of the authentication. In spite of being there, it is possible to improve the refusal rate for rejecting identity.
[0034]
In addition to the above control, if the user has the IC card 1 and can check with the IC card, the door unlocking is performed when the door unlocking IC card reader 2 receives the radio wave from the IC card 1. The fingerprint authentication device 5 may be shifted from a standby state to an activated state where fingerprint authentication is possible. As a result, when the person to be authenticated touches the door unlocking fingerprint authentication device 5 with his / her finger, the fingerprint authentication processing can be performed immediately, so that the authentication time can be shortened and convenience is improved.
[0035]
<Control details of door unlocking using IC card and fingerprint authentication>
The following control example shows a case where the user unlocks the door using both the IC card 1 and fingerprint authentication.
[0036]
As shown in FIG. 2, the door unlocking IC card reader 2 reads the identification information from the IC card 1 in step S1 (YES in step S1), and the identification information registered in the IC card 1 in step S2 is stored in advance on the vehicle side. (Step S2: YES), the door unlocking fingerprint authentication device 5 is activated in step S3 to enable fingerprint authentication. If the identification information registered in the IC card 1 in step S2 does not match the information registered in advance on the vehicle side (NO in step S2), abnormal information such as collation failure is indicated in step S8 as a horn or direction indicator lamp. Alternatively, the notification is given through a display on the vehicle interior or an audio speaker.
[0037]
In step S4, since the door is unlocked by using both the verification using the IC card 1 and the fingerprint authentication, the door is only used for the fingerprint authentication without performing the verification using the IC card 1 (without holding the IC card 1). The authentication threshold value by the door unlocking fingerprint authentication device 5 is set lower than in the case of unlocking. This authentication threshold increases the authentication success rate by, for example, reducing the number of feature points of the fingerprint required for fingerprint authentication from the normal time.

And a standard value that is higher than the authentication threshold when fingerprint authentication is used together.
[0045]
Next, in step S24, the door unlocking fingerprint authentication device 5 reads the fingerprint as the user's feature information (YES in step S24), and in step S25, if the feature information matches the information registered on the vehicle side in advance ( In step S25, YES), in step S26, the authentication control unit 6 outputs an unlock signal to the door lock control device 7, and the door lock control device 7 brings the door lock mechanism 4 into an unlocked state.
[0046]
If the user cannot read the fingerprint as the feature information of the user even though the user touches the door unlocking fingerprint authentication device 5 in step S24 (NO in step S24), the user is prompted in step S29. In order to prompt the user to re-enter the fingerprint, notification is given by a horn, a direction indicator lamp, a display in the vehicle interior, a voice speaker, or the like.
[0047]
After notifying the re-input in step S29, the process after step S24 is executed again until a predetermined time elapses in step S30, and after the predetermined time elapses, the process proceeds to step S27 and abnormal information such as a collation failure is classified into horns. And a direction indicator lamp, or a display on the vehicle interior or an audio speaker.
[0048]
If the user feature information does not match the information registered in advance in the vehicle in step S25 (NO in step S25), the process passes through steps S29 and S30 as many times as preset in step S28. If the fingerprint authentication process is executed again and the set number of times is not satisfied but the two do not match (YES in step S28), the process proceeds to step S27 and abnormal information such as a collation failure is indicated by a horn, direction indicator lamp, or Notification is given by a display on the passenger compartment or a voice speaker.
