Embodiment Construction

[0039] As the best embodiment of the present invention, it includes a human body sensing module, a vehicle control module, an identity identification module and an unlocking control module, such as figure 1 , 2 shown. The human body sensing module is connected with the vehicle control module, and wireless communication is performed between the vehicle control module and the identification module. The human body sensing module is located on the door handle, and when the human body sensing module senses that someone pulls the door handle, it sends a trigger signal to the vehicle control module. The vehicle control module includes a first signal transmitting unit, a first encryption key unit, a serial number generating unit, a random number generator, a first counter, a first encrypted information generating unit, a first signal receiving unit and a first identity verification unit, After the on-board control module receives the trigger signal, the first encrypted information g...

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...
