Abstract

The invention aims to provide an electric vehicle brake lamp control method and system as well as a vehicle so as to solve the problem that in the prior art, in the case of an electric vehicle which is in a self-adaptive cruise mode, a brake lamp cannot be turned on or turned off according to the vehicle braking condition, so that a rear-end collision of a rear vehicle is caused. The electric vehicle brake lamp control method comprises the following steps that when the vehicle is in a self-adaptive cruise mode, the current acceleration of the vehicle, a current brake pedal position signal anda brake signal output by an ESP system are acquired; and turning-on and turning-off of a brake lamp of the vehicle is controlled according to the current acceleration of the vehicle, the current brakepedal position signal or the brake signal output by the ESP system.

Description

technical field [0001] The invention relates to the field of control of brake lights of automobiles, in particular to a method and system for controlling brake lights of electric vehicles and an automobile. Background technique [0002] The function of the brake light of the car is to prompt the vehicles behind to prevent the rear-end collision of the vehicles, and it has other important functions in the field of car safety. [0003] For traditional fuel vehicles, when the vehicle is performing adaptive cruise control, the longitudinal control of the vehicle (which can be understood as accelerator torque and brake control) is controlled by the body control unit. Traditional fuel vehicles control the vehicle for deceleration braking or braking. When the brake pedal is activated, it is controlled to turn on and off by receiving the brake pedal signal and the control signal of the ESP system. [0004] As motor-driven electric vehicles become more and more popular, the adaptive...
