Description

technical field [0001] The invention relates to a car key, in particular to an intelligent car key system based on a vehicle control system and a working method thereof. Background technique [0002] Automobile BCM (Automobile Body Control Module) is one of the most important modules in the automobile. At present, there are three main methods: decentralized, centralized and distributed (bus type). BCMs are used to control common "body" functions that do not require dedicated controllers, including functions such as window, mirror, door lock and light control, as well as RF receivers that receive information from vehicle keys and tire pressure monitors. In addition, BCM also acts as a gateway to transmit data between different modules through the network bus. Because the BCM connects multiple vehicle buses, it is an ideal platform for adding new functions to the vehicle. Although the requirements of automotive BCM vary from vehicle to vehicle, at present, they generally...
