According to the intelligent key system and the working method thereof, the structure is novel, the use procedure is clear, a user can obtain an automobile conveniently and timely. The intelligent key system comprises an intelligent key and a host connected with an automobile body controller in the automobile control system, the intelligent key comprises a first control unit, a first power source circuit, a first high frequency circuit, a first low frequency circuit, a first confidentiality circuit, a sound circuit, a display circuit and a vibration circuit; the host comprises a second control unit, a second storage circuit, a second power source circuit, a second high frequency circuit, a second low frequency circuit, a second confidentiality circuit, a wireless charging circuit and an automobile body network interface circuit. According to the intelligent key system based on the automobile control system and the working method thereof, the structure is novel, the use process is simple and convenient, the use procedure is clear, and a good use effect and great convenience are achieved through combination and application of a mobile phone, the intelligent key, the host and the automobile body controller.

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...
