A car key learning method, system, vehicle control device and storage medium

Abstract

The invention relates to a car key learning method, system, vehicle control equipment and storage medium, which belongs to the field of automotive electronics technology, wherein the method includes: after receiving the matching start signal sent by the diagnostic instrument, entering the learning mode; If the pairing request signal sent by the target car key is received within the set pairing time window, the key code carried in the pairing request signal will be identified; a random encrypted confirmation signal will be generated based on a preset custom algorithm; the encrypted confirmation signal will be fed back to make the target car key Decrypt the encrypted confirmation signal; if the correct decoding result of the encrypted confirmation signal fed back by the target car key is received within the pairing time window, the key code is stored; when a preset number of key codes or pairing time is newly stored After the window closes, exit study mode. The application has the effect of improving the reliability of the car key and further improving the safety.

Description

technical field [0001] The invention relates to the field of automobile electronic technology, in particular to a method and system for learning a car key, a vehicle control device and a storage medium. Background technique [0002] With the development of science and technology and the improvement of people's living standards, cars have gradually become an indispensable means of transportation in people's daily life. In order to facilitate people's control of cars, wireless smart car keys have also emerged at the historic moment. [0003] In the field of automobile offline and after-sales service, it is often necessary to match the car key. In related technologies, the car key is usually equipped with an identification code function. At present, the common car key learning is mainly composed of the car key and the door control device of the vehicle. Carry out wireless communication and carry out recognition learning. When unlocking, the car key and the door control device...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned related technologies have the following defects: the car key and the door control device in the vehicle perform identity verification through wireless communication. Since the wireless communication channel is an open channel, the risk of communication information being intercepted is relatively high. Therefore, whether it is In the process of car key pairing and learning, or in the process of unlocking the car with the car key, there is a possibility that the signal will be intercepted, resulting in a greater possibility of the car key being mispaired or forged, which in turn increases the risk of vehicle theft
