To provide an abnormality diagnosis method for a brake pedal module that can detect an abnormality in which the position of a brake pedal no longer changes in a pedal module equipped with a sensor for detecting the position of the pedal.SOLUTION: A pedal module includes a pedal that receives a pedal force Y, a pedal arm that has the pedal on one end side and is rotatable about the other end as a rotational center when the pedal is stepped down, an angle detection unit capable of detecting a rotation angle X of the pedal arm, and a pedal force detection unit capable of detecting the pedal force Y. When the pedal arm of the pedal module stops moving at a rotation angle X1, it is diagnosed that an abnormality has occurred in the brake pedal module when the pedal force Y exceeding an allowable upper limit Y2 obtained by adding a predetermined value C to a normal value Y1 of the pedal force Y corresponding to the rotation angle X1 detected by the angle detection unit is detected by the pedal force detection unit.SELECTED DRAWING: Figure 1
【課題】ペダルの位置を検出するセンサを備えたペダルモジュールにおいて、ブレーキペダルの位置が変化しなくなった異常を検知できるブレーキペダルモジュールの異常診断方法を提供すること。【解決手段】踏力Yを受けるペダルと、ペダルを一端側に有しペダルが踏み込まれたときに他端側を回転中心として回動可能なペダルアームと、ペダルアームの回転角度Xを検出可能な角度検出部と、踏力Yを検出可能な踏力検出部と、を備えたペダルモジュールのペダルアームが回転角度X1で移動しなくなった場合、角度検出部により検出された回転角度X1に対応する踏力Yの正常値Y1に所定値Cを加算した許容上限Y2を超えた踏力Yが踏力検出部によって検出されたときにブレーキペダルモジュールに異常が発生したと診断する。【選択図】図1
