The invention discloses a brake lamp control system and method. The vehicle body controller BCM sends out a request signal through a double-loop pedal travel sensor, an electronic parking brake systemEPBi and a vehicle control unit VCU, after judgment is conducted according to preset control logic, a control level signal is sent to a brake lamp control circuit, the brake lamp control circuit controls a relay to be switched off or switched on, and therefore diversified and accurate control over the brake lamp is achieved.
本发明公开的一种制动灯控制系统及方法,车身控制器BCM根据双回路踏板行程传感器、电子驻车制动系统EPBi、整车控制器VCU发出的请求信号,根据预设的控制逻辑判断后,发送控制电平信号至制动灯控制电路,制动灯控制电路控制继电器断开或者吸合,从而实现对制动灯的多样化准确控制。
