Motor vehicle light control system

Abstract

The invention discloses a motor vehicle lamp control system and relates to the technical field of motor vehicle lamp control. The system has a front light control device and a rear light control device; the front light control device includes a microcontroller I, a communication module I connected with the microcontroller I, a left turn light switch connected with the microcontroller I, Right turn light switch, reverse light switch, brake light switch, width light switch, fog light switch and license plate light switch, front light driver connected with microcontroller Ⅰ, front left turn light connected with front light driver , front right turn light and front width indicator light, high beam light, low beam light and front fog light are directly connected with their corresponding switches; the rear light control device includes a microcontroller Ⅱ, and a communication module Ⅱ connected with the microcontroller Ⅱ , the rear lamp driver connected with the microcontroller II, the rear lamp connected with the rear lamp driver; the communication module I and the communication module II are connected through a serial bus. The advantages are: reducing the number of wiring harnesses and improving the reliability of control.

Description

technical field [0001] The invention relates to the technical field of motor vehicle lamp control, in particular to a motor vehicle lamp control system, which is suitable for the lamp control of electric tricycles, motorcycle tricycles and related vehicles. Background technique [0002] With more and more electrical equipment used in vehicles, from engine control to transmission system control, from driving, braking, steering system control, safety assurance system, instrument alarm system, and car lights and lights control, the motor vehicle electrical system A complex large system is formed, and all of them are controlled in the cab. Higher requirements are put forward for the integrated wiring of vehicles and the sharing and interaction of information. From the perspective of wiring, most of the traditional electrical systems use a single point-to-point communication method, with little connection with each other, which will inevitably lead to a huge wiring system, which...

AI Technical Summary

Problems solved by technology

The traditional control method of the motor vehicle light system is to use manual switch control, that is, to control the front lights of the vehicle and the rear lights of the vehicle, and to control the front lights. The front lamp is far away from the control switch, and there are many types of rear lamps, and there are many wire harnesses leading to the rear side of the vehicle, so the cost of the wire harness is relatively high, which also has a certain impact on reliability.
