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 CAN network-based brake light control system and a control method thereof, which improve driving safety. The system includes input, brake controller and output. The input includes wheel speed sensor input, downhill auxiliary switch input, electronic handbrake switch input, brake normally open switch input, gear signal input, and engine controller signal input. And the input of the radar ranging controller used to measure the safe distance in front of the vehicle, the output end includes the brake connected to the brake controller and the body controller, the body controller is connected to the brake light, wherein, the input of the wheel speed sensor, the downhill Auxiliary switch input, electronic handbrake switch input, brake normally open switch input and brake controller are hard-wired, gear signal input, engine controller signal input, radar ranging controller input and brake controller are CAN bus connect. The invention judges various running conditions of the vehicle, brakes the vehicle before the driver reacts to the danger, and requests the vehicle body controller to turn on or turn off the brake light, so as 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 ...
