Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle keyless entry system, and more particularly to a personal identification method and a personal identification system suitable for realizing the vehicle keyless entry system.

[0002]

2. Description of the Related Art Conventionally, when a door lock button or a door open button of an electronic key is operated to lock or open a door of a vehicle, the door does not have to be inserted into a key cylinder and rotated. A wireless type keyless entry system capable of performing lock and door opening is known.

A keyless entry system called a smart key system is also known. This smart key system sends a request signal from the in-vehicle transmitter when the user carrying the electronic key approaches within a predetermined range of the vehicle, and the electronic key receives the request signal and returns a response signal. Based on the information received by the in-vehicle receiver and obtained by repeating the request and response several times, the in-vehicle security ECU performs key verification, and if the key is legitimate, then the user touches the door knob. It is installed near the doorknob when a user with a legitimate key gets off the vehicle and closes the door when the sensor built into the doorknob detects that the door is turned on. When the door lock button is pressed, the door lock is executed.

According to these conventional keyless entry systems, the user does not have to insert the key into the key cylinder to perform a mechanical operation for locking / unlocking the door, and therefore, the locking / unlocking of the door. The effect that the burden on the user due to is reduced is exhibited.

[0005]

However, in these conventional keyless entry systems, the user must carry the electronic key without fail, so if the user forgets to leave the electronic key at home or loses the electronic key. However, there is a problem that the user himself cannot use the vehicle. Also, if someone stole the electronic key, they could also easily unlock the vehicle door using the electronic key, so the vehicle itself could be stolen or stolen in the vehicle. There is a problem that the existing article or the equipment mounted on the vehicle may be stolen.

As a method of solving such a problem, for example, a method of registering the fingerprint of the user and allowing the user to touch the fingerprint detection sensor near the door knob when the user tries to open the door is adopted. Then, the door can be unlocked without carrying the electronic key. However, there is a problem that the security is not sufficient because the fingerprint can be collected from the article touched by the user and the fingerprint may be stolen by a criminal. In addition, the door cannot be opened unless the fingerprint detection sensor is touched before the door knob is touched, which is troublesome.

In order to solve the problems when the personal identification method using the fingerprints is adopted, a keyless entry system for confirming the identity by adopting the personal identification method using the iris data, which is being practically used in ATMs of banks. Can be suggested. According to this method, the iris data is very unlikely to be stolen like a fingerprint, which is extremely preferable in terms of security, and the amount of information required for personal identification by the iris data is smaller than that by the fingerprint. Another advantage is that it is possible to reduce the price of the equipment required for personal identification. Furthermore, since it is a non-contact type, there is also an advantage that it is completely free of trouble.

However, when trying to acquire the iris data from a user standing near the vehicle to open the door, the height of the eyes changes depending on the height of the user's height, so that the user's eyes are close to the camera. However, there is a problem that it is difficult to match the installation location of the camera, the shooting direction of the camera, etc. For example, when the user is a woman, the average height is about 155 cm, but when the user is a man, the average height is about 170 cm, and there is a considerable difference depending on whether the user is male or female. Moreover, even if only men are seen, recently, there are many people whose height is 180 cm or more, while there are many people whose height is 160 cm or less, and individual identification based on iris data is becoming more difficult.

Further, when the door is unlocked by the personal identification method using the iris data, there is a problem how to set the photographing timing by the camera. In other words, if the camera is continuously driven during parking in order to unlock the door using the iris data, the power consumption will be large, which may cause the battery to run out. .

Further, a user who is trying to drive a vehicle may wear sunglasses, or may have a baggage at a different standing position, and even if he or she cannot obtain the iris data of the user, this may not be possible. is there.

In addition, the human pupil expands or contracts depending on the ambient brightness. Therefore, the iris also changes its shape depending on the ambient brightness. In this respect, as described in Japanese Patent Publication No. 5-84166, when acquiring the iris data, the irradiation angle and intensity of light are variously changed to make the pupil a predetermined size and then the iris data is obtained. A method has been proposed in which accurate personal identification is performed by performing acquisition. However, in such a method, there is a problem that it takes a long time for individual identification, or the structure and control of the lighting device become complicated.

Therefore, an object of the present invention is to solve the above-mentioned problems in unlocking a vehicle door by a personal identification method using iris data and establish it as a practical application technique. It is a thing. At the same time, it is an object of the present invention to provide a new personal identification method and a personal identification system that can establish such a practical application technique.

More specifically, according to the present invention, when the vehicle door is unlocked by the personal identification method using the iris data, the iris data can be surely acquired regardless of the physical constitution of the user. The first purpose is to be able to do so.

Further, according to the second aspect of the present invention, when the vehicle door is unlocked by the personal identification method using the iris data, the power consumption is reduced by operating the camera at an optimum timing. It is intended.

A third object of the present invention is to ensure that the iris data can be acquired when the vehicle door is unlocked by the personal identification method using the iris data. .

In addition, a fourth object of the present invention is to enable quick and accurate personal identification when unlocking a vehicle door by a personal identification method using iris data. Is.

A fifth object of the present invention is to provide a novel personal identification method suitable for achieving the above first to fourth objects.

In addition, a fourth object of the present invention is to provide a novel personal identification system suitable for achieving the above first to fourth objects.
