Distributed Wireless Body Control System

Abstract

A distributed wireless vehicle body control system, including positioning antennas arranged at multiple positions of the vehicle body, characterized in that it also includes: a body control main module, which is integrated with the main control module of the keyless entry system, through which the main control module Communicate with positioning antennas everywhere; the regional body control modules arranged at multiple positions of the vehicle body are respectively integrated with the positioning antennas at the corresponding positions, or are set close to the positioning antennas at the corresponding positions; each regional body control module is configured to communicate with the positioning antennas at the corresponding positions The integrated positioning antenna or an adjacent positioning antenna receives the body control signal sent by the body control main module to perform corresponding control actions on the body parts in its area; the body control main module responds to the user's operation on the in-vehicle input The vehicle body control signal, the body control main module and the input module in the vehicle communicate through the vehicle bus. The above wireless body control system can reduce wiring complexity and wiring cost.

Description

technical field [0001] The invention relates to vehicle body control technology, in particular to a vehicle body control system that utilizes wireless communication to realize distributed vehicle body control functions. Background technique [0002] In some vehicles, the body controller is generally used to control body parts such as lights, central locking, power windows, rearview mirrors, etc. in a unified manner. At present, the more commonly used method is to set the driving circuits of each body part in the body controller, and connect the body controller to the above-mentioned many body parts through cables, so as to realize the control of the body controller on the above-mentioned many body parts. However, since the above-mentioned many components are distributed in various parts of the vehicle body, the wiring is very complicated. Moreover, since the price of the cable itself is not cheap, the more components that need to be connected, the higher the corresponding w...

AI Technical Summary

Problems solved by technology

However, since many of the above components are distributed in different parts of the vehicle body, the wiring is very complicated

Moreover, since the cable itself is not cheap, the more components that need to be connected, the higher the corresponding wiring cost

As more and more functions are expected to be included in the scope of "body control" at present, the complexity and cost of the above wiring are further increased
