Problems solved by technology

Traditionally, the brake light can be turned on only when the driver steps on the brake pedal, but in many cases, such as a brake pedal failure or an emergency, the driver is too late to step on the brake, resulting in the failure to turn on the brake light in time to convey the brake information to the driver. Rear-end accidents caused by vehicles behind

Abstract

The invention provides a brake lamp control system based on a CAN network and a control method thereof to improve the security of driving. The system comprises an input end, a brake controller, and an output end. The input end comprises wheel speed sensor input, downhill auxiliary switch input, electronic hand brake switch input, brake normally open switch input, gear signal input, engine controller signal input, and radar ranging controller input used to measure the safe distance in front of a vehicle. The output end comprises a brake connected with the brake controller, and a vehicle body controller connected with a brake lamp. The wheel speed sensor input, the downhill auxiliary switch input, the electronic hand brake switch input and the brake normally open switch input are connected with the brake controller by a rigid line. The gear signal input, the engine controller signal input and the radar ranging controller input are connected with the brake controller by a CAN bus. According to the invention, various driving conditions of a vehicle are judged, vehicle braking is executed when there is danger but the driver fails to react, and the vehicle body controller is requested to turn on or off the brake lamp to reduce the occurrence of accidents.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a CAN network-based brake light control system and a control method thereof. Background technique [0002] With the rapid development of the automobile industry, cars have gradually entered thousands of households and become a necessary means of transportation. Casualties and property damage also gradually increased. Automobile safety performance and related devices are getting more and more attention. Brake lights play an important role in transmitting traffic information in car driving. They are one of the important signal devices for cars to warn the rear vehicles to slow down or stop, and to ensure driving safety. Traditionally, the brake light can be turned on only when the driver steps on the brake pedal, but in many cases, such as a brake pedal failure or an emergency, the driver is too late to step on the brake, resulting in the failure to turn on ...
