A brake operation sensor detects the position of an input member. An angular sensor detects the position of a power piston. An ECU drives and controls an electric motor on the basis of the relative positions of the input member and power piston. The relative displacement of the input member and power piston is mechanically limited by mutual abutment thereof with a level difference therebetween. The ECU advances and retracts the power piston independent of the movement of the input member and determines, on the basis of the detected relative positions, the state of abutment between the input member and power piston due to the mechanical limit. On the basis of this determination, the ECU corrects the relative positions of the input member and power piston to control the electric motor.

    制动操作传感器检测输入部件的位置。角度传感器检测动力活塞的位置。ECU基于输入部件和动力活塞的相对位置,驱动并控制电动马达。其中,输入部件和动力活塞通过以台阶彼此抵接,而它们的相对位移被机械地限制。ECU不通过输入部件的移动而使动力活塞进行进退移动,基于检测到的相对位置判定由机械的限制引起的输入部件和动力活塞的抵接状态。而且,基于该判定,ECU修正输入部件和动力活塞的相对位置而控制电动马达。
