PROBLEM TO BE SOLVED: To provide a stroke sensor improving a resolution power in the vicinity of starting to step on a brake pedal or finishing to step on the brake pedal.SOLUTION: A stroke sensor 1 is schematically comprising: a magnet 12 rotating according to the stroke of a brake pedal 6, the magnet 12 being provided on an end part 100 of a rotation axis 10 of a brake pedal 6; a first magnetic sensor 21 provided opposed to the magnet 12 and outputting a first detection signal Sby a change of the direction of a magnetic field 120 accompanied with the rotation of the magnet 12 and a second magnetic sensor 22 for outputting a second detection signal S; and a signal generation part 25 for generating a first output signal Sfor converting the first detection signal Sand taking a slope of the later half signal as being steeper than the first half signal of a stroke L of the brake pedal 6, and a second output signal Sfor converting the second detection signal Sand taking the slope of the later half signal as being steeper than the first half signal of the stroke L of the brake pedal 6.SELECTED DRAWING: Figure 3

    【課題】ブレーキペダルの踏み始めや踏み終わりの近傍における分解能を向上させたストロークセンサを提供する。【解決手段】ストロークセンサ1は、ブレーキペダル6の回転軸10の端部100に設けられ、ブレーキペダル6のストロークLに応じて回転する磁石12と、磁石12と対向して配置され、磁石12の回転に伴う磁場120の方向の変化によって第1の検出信号S1を出力する第1の磁気センサ21、及び第2の検出信号S2を出力する第2の磁気センサ22と、第1の検出信号S1を変換してブレーキペダル6のストロークLの後半よりも前半の信号の傾きを急峻とする第1の出力信号S3、及び第2の検出信号S2を変換してブレーキペダル6のストロークLの前半よりも後半の信号の傾きを急峻とする第2の出力信号S4を生成する信号生成部25と、を備えて概略構成されている。【選択図】図3
