Description

technical field [0001] The invention relates to an automobile body control system, in particular to an automobile body network control system and a control method thereof. Background technique [0002] At present, the automobile body control usually adopts the traditional wiring harness control method and the network control method. Among them, the traditional wiring harness control is to realize the control of car lights, doors and windows, rearview mirrors, etc. through relays; In terms of technological development trends and application prospects, it lags far behind the network control system and will gradually be replaced by network control methods. The network control method is to realize the control function by forming a local network through the bus, but the function of the existing vehicle network control is mainly responsible for the control of the car door, and its structure is as follows: figure 1 As shown, a body network is formed by a central control unit and ...

AI Technical Summary

Problems solved by technology

Its shortcomings are: there is no control on the front and rear lights, wipers and washing pumps; relays and fuses are still used in high-power electrical equipment such as wipers and lights, and electromagnetic interference is serious; the wiring harness under the instrument panel is basically complicated. No change, no display of temperature inside and outside the car and real-time display of fault information; no automatic protection of electric equipment such as lights and elevators and self-recovery function after troubleshooting
