1. A smart entry system for a vehicle comprising:
- communication means for radio communication with a portable device carried by a user of a vehicle;
first validation means for validating the portable device by comparing identification information of the portable device received by the communication means with pre-stored first registration information indicative of a specified portable device;
biometric information detection means having a light inlet opening for detecting biometric information of the user based on light including the biometric information and passing through the light inlet opening;
second validation means for validating the user by comparing the biometric information detected by the detection means with pre-stored second registration information indicative of a specified user;
vehicle control means for executing a predetermined vehicle control when both the portable device and the user are validated by the first validation means and the second validation means, respectively; and
exposure control means for exposing the light inlet opening to the light thereby to render the detection means operable, only when the portable device is validated by the first validation means.

Abstract
An entry control system includes a portable device carried by a vehicle user and a biometric sensor attached to a vehicle door. The biometric sensor includes a CCD camera and a shutter. The shutter is moved to uncover the CCD camera only when the portable device is validated. After the biometric sensor detects the biometric information based on a finger print image of the user, the shutter is moved again to cover the CCD camera. Each time the shutter moves, a brush cleans the CCD camera. The vehicle door is enabled to be opened only when the user is validated based on the biometric information.

8. A method for controlling entry of a user through a door, the method comprising:
-
holding normally a biometric device disabled to be exposed to light so that the biometric device is protected from being stained;
detecting whether the user approaches the door;
enabling the biometric device to be exposed to the light thereby to detect biometric information of the user by the biometric device in response to a detection of approach of the user;
enabling the user to open the door only when the user is validated based on the biometric information detected by the biometric device; and
disabling again the biometric device to be exposed to the light. - View Dependent Claims (9, 10)
