Abstract

The invention discloses a lighting control method and system for automobile emergency braking. The method comprises the steps: when a vehicle body electronic stabilization system monitors that the vehicle speed during vehicle driving is larger than or equal to a vehicle speed threshold value and the deceleration of a vehicle is larger than or equal to a deceleration threshold value, the vehicle body electronic stabilization system outputs a brake response CAN signal in an activated state to a vehicle body controller; and after receiving the brake response CAN signal in the activated state, thevehicle body controller controls the rear brake lamp and the high brake lamp to flicker at a preset frequency through a hard wire so as to enter an emergency brake flickering mode. The entering and exiting of the emergency braking flickering mode are controlled by the vehicle body electronic stabilizing system and the vehicle body controller and can be achieved through internal programs of the vehicle body electronic stabilizing system and the vehicle body controller, so that external interference is avoided and reliability is high; the system is free of any new electronic components, and vehicle wiring harnesses and hardware layout do not need to be changed, so that the cost is low, and in addition, deviation and time delay can be effectively reduced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and system for controlling the lights of emergency braking of automobiles. Background technique [0002] Brake lights are an important part of a car. The significance of developing the emergency braking function of brake lights is that when the driver brakes urgently, it can remind the vehicle behind to avoid braking in time, thereby reducing the risk of rear-end collision and improving the safety performance of the vehicle. [0003] At present, there are many types of cars with emergency brake flashing on the brake light on the market, but most of them use new inertial sensing components to control the flashing of the brake light, which is not only costly to implement, but also susceptible to external interference and poor reliability. However, the traditional method of realizing emergency brake flashing through inertial physical perception sensors also has a large ...
