The invention discloses a brake lamp control method and system based on a brake-by-wire system and a vehicle. The brake lamp control method comprises the steps that the brake-by-wire system comprises a brake pedal simulator, a pressure sensor and a control module; the method comprises the steps that a brake pedal simulator and a pressure sensor respectively collect a brake pedal travel signal and a pipeline pressure signal in real time; the control module judges whether the brake pedal travel signal is greater than or equal to a preset travel value or the pipeline pressure signal is greater than or equal to a preset pressure value; if yes, it is indicated that braking exists, a first braking signal is sent to a vehicle control unit, and a braking lamp is controlled to be in a turned-on state; if not, it is indicated that braking does not exist, a second braking signal is sent to the vehicle control unit, and the braking lamp is controlled to be in an off state. According to the brake lamp control method and system based on the brake-by-wire system and the vehicle, the reliability and accuracy are improved, and the complexity of a whole vehicle framework and the whole vehicle cost are reduced.
本发明公开了一种基于线控制动系统的制动灯控制方法及系统、车辆,步骤包括:线控制动系统包括制动踏板模拟器、压力传感器和控制模块;步骤包括:制动踏板模拟器和压力传感器分别实时采集制动踏板行程信号和管路压力信号;控制模块判断制动踏板行程信号是否大于等于预设行程值或管路压力信号是否大于等于预设压力值;若是,表示有制动,向整车控制器发出第一制动信号,控制制动灯处于点亮状态;否则,表示无制动,向整车控制器发出第二制动信号,控制制动灯处于熄灭状态。通过本发明的基于线控制动系统的制动灯控制方法及系统、车辆,提升了可靠性和准确性,降低了整车架构的复杂程度及整车成本。
