Identity recognition system for keyless entering automobile and its recognition method

Abstract

The invented identity identification system includes car-mounted control module, identity identification module and unlocking control module. Its identity identification method includes the following steps: car-mounted control module can produce first encrypted information produced by using first encrypted key, serial number, random data and instantaneous data rolling code of counter and transmit the signal with first encrypted information; the identity identification module can be used for receiving said signal to make identity identification, producing second encrypted information produced by using first encrypted information and second encrypted key and transmitting the feedback signal with second encrypted information; the car-mounted control module can be used for receiving said feedback information, making identity identification and controlling unlocking control module to execute unlocking operation.

Description

【Technical field】 [0001] The invention relates to the field of automobiles, in particular to an identification system and identification method for keyless entry into automobiles. 【Background technique】 [0002] At present, more and more cars have entered the field of work and life of people. While people require the convenience of using cars, people pay more and more attention to the safety of cars. There are many ways to enter the car, from opening the door with a key to opening the door with a remote control. Recently, with the market demand And with the development of electronic technology, some long-distance induction unlocking devices have appeared, that is, the vehicle-mounted control module on the car continuously sends out low-frequency signals. The low-frequency signal returns a signal with identity password information, and the on-board control module senses the signal and executes the unlocking action after passing the identity recognition. This device facilita...

Problems solved by technology

[0003] The main purpose of the present invention is to solve the problem that the password of the identity identification module in the prior art is easily intercepted, to provide an identification system and identification method for keyless entry into the car, to perform double identity authentication, and there are fixed parts in the password , and the random part

[0004] The second object of the present invention is to provide a keyless entry vehicle identification system and identification method to solve the problem in the prior art that there is no judgment on whether the owner wants to enter the vehicle and the control module on the vehicle consumes a lot of energy. When the owner is about to enter the car, the control module sends out a low-frequency signal

[0005] Another object of the present invention is to solve the problem that the door cannot be opened when the battery on the identity module is out of power in the prior art, and to provide an identity recognition system and method for keyless entry into the car, so that the battery on the identity module Can still return signal in case of no power
