A brake pedal displacement detection system according to an embodiment of the present invention includes a shaft that moves in conjunction with a brake pedal, a magnet that is supported by the shaft and generates a magnetic field, and a displacement detection device that detects a change in magnetic flux corresponding to a movement of the magnet and detects a displacement of the brake pedal. The control device is used for generating a brake control signal according to a measurement value of the displacement detection device; the displacement detection device includes a pedal wake-up sensor that generates a wake-up signal for activating the control device by detecting a change in magnetic flux, and a pedal stroke sensor that has a plurality of detection parts that independently detect the magnetic flux and measures a stroke of a brake pedal by detecting a change in magnetic flux; the control device verifies the reliability of the measured values measured by the plurality of detection units of the pedal stroke sensor by using the measured values of the pedal wake-up sensor.

    本发明提供一种制动踏板的位移检测系统及位移检测方法,本发明的实施例的制动踏板的位移检测系统包括:轴,以与制动踏板联动的方式运动,磁铁,由所述轴支撑并产生磁场,位移检测装置,检测与所述磁铁的移动对应的磁通量的变化,以及控制装置,根据所述位移检测装置的测量值来生成制动控制信号;所述位移检测装置包括:踏板唤醒传感器,通过检测磁通量的变化,来生成用于激活所述控制装置的唤醒信号,以及踏板冲程传感器,具有独立检测磁通量的多个检测部,通过检测磁通量的变化来测量制动踏板的冲程;所述控制装置利用所述踏板唤醒传感器的测量值,来验证所述踏板冲程传感器的多个所述检测部分别测量到的测量值的可靠性。
