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

Abstract

The invention relates to a car key learning method and system, a vehicle-mounted control device and a storage medium, and belongs to the field of automotive electronics technology. The method comprises: after a matching starting signal sent by a diagnostic instrument is received, entering a learning mode; if a pairing request signal sent by the target vehicle key is received in the preset pairing time window, identifying a key code carried in the pairing request signal; generating a random encryption confirmation signal based on a preset customization algorithm; feeding the encryption confirmation signal back so that the target vehicle key can decrypt the encryption confirmation signal; if a correct decoding result which is fed back by the target vehicle key and aims at the encryption confirmation signal is received in the pairing time window, storing the key code; and after the preset number of key codes are newly stored or the pairing time window is closed, exiting the learning mode. The method has the advantages that the reliability of the vehicle key is improved, and then the safety is improved.

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...
