The invention discloses a brake pedal displacement detection module and a brake pedal displacement detection system. The brake pedal displacement detection module comprises a displacement sensor used for detecting the displacement of a brake pedal; the switch sensor is used for detecting whether a brake pedal is stepped down or not; and the driving circuit is used for controlling the on-off of a power supply loop of the displacement sensor according to a detection signal of the switch sensor. When the switch sensor detects that the brake pedal is stepped down, the driving circuit switches on a power supply loop of the displacement sensor so as to supply power to the displacement sensor; and when the switch sensor detects that the brake pedal is not stepped down, the driving circuit cuts off the power supply loop of the displacement sensor so as to stop supplying power to the displacement sensor. According to the invention, when the brake pedal is not stepped down, the displacement sensor for detecting the displacement of the brake pedal is in the uncharged dormant state, so that the power consumption of the intelligent brake system can be greatly reduced.
本发明公开一种刹车踏板位移检测模块和刹车踏板位移检测系统。所述刹车踏板位移检测模块包括:位移传感器,用于检测刹车踏板的位移;开关传感器,用于检测刹车踏板是否被踩下;和驱动电路,用于根据所述开关传感器的检测信号控制所述位移传感器的供电回路的通断。当所述开关传感器检测到所述刹车踏板被踩下时,所述驱动电路接通所述位移传感器的供电回路,以向所述位移传感器供电;当所述开关传感器检测到所述刹车踏板未被踩下时,所述驱动电路切断所述位移传感器的供电回路,以停止向所述位移传感器供电。在本发明中,在刹车踏板未被踩下时,用于检测刹车踏板位移的位移传感器处于不带电的休眠状态,因此,能够极大地降低智能刹车系统的功耗。
