The purpose of the present invention is to control a pressing/pushing force with high precision regardless of the individual difference, use condition, and the like of a brake device. When controlling an electric motor (8) that imparts thrust to a piston that presses a brake pad, the present invention calculates, as a plurality of candidate values (c1, c2, c3), a current and a voltage during an idle current period, or a change in a function comprising the current and the voltage during the idle current period, during a current change period prior to the idle current period. Then, at a predetermined time T0 during the current change period, one of a plurality of candidate values (c1, c2, c3) is selected on the basis of the current and the voltage, and on the basis of the current and the voltage related to the selected candidate value or a change in the function, a characteristic parameter of the motor (8) is calculated, and a stop current of the motor (8) is calculated.

    本发明的目的在于,不管制动装置的个体差和使用状况等,均高精度地控制按压推力。本发明在控制对按压制动块的活塞赋予推力的电动机(8)时,在怠速电流期间前的电流变化期间,将怠速电流期间的电流和电压、或由电流和电压构成的函数的变化作为多个候选值(c1、c2、c3)来进行运算。然后,在上述电流变化期间中的规定时间T0,基于上述电流和上述电压,选择多个候选值(c1、c2、c3)中的某一个,基于与选择出的候选值相关的上述电流和上述电压、或上述函数的变化,运算电动机(8)的特性参数,且运算电动机(8)的停止电流。
