To accurately control pressing thrust irrespective of an individual difference of brake devices and a use state.SOLUTION: When controlling a motor 8 which imparts thrust to a piston for pressing a brake pad, a current and a voltage in an idling current period, and a change of a function constituted of the current and the voltage are calculated as a plurality of candidate values (c1, c2 and c3) in a current change period before the idling current period, one of the plurality of candidate values (c1, c2 and c3) is selected at a prescribed time T0 in the current change period on the basis of the current and the voltage, a characteristic parameter of the motor 8 is calculated on the basis of the current and the voltage related to the selected candidate value, or a change of the function, and a stop current of the motor 8 is calculated.SELECTED DRAWING: Figure 8

    【課題】ブレーキ装置の個体差や使用状況などによらず押圧推力を精度よく制御する。【解決手段】ブレーキパッドを押圧するピストンに推力を与えるモータ8を制御するにあたり、アイドリング電流期間前における電流変化期間に、アイドリング電流期間の電流及び電圧、又はこれらから構成される関数の変化を複数の候補値(c1,c2,c3)として演算し、前記電流変化期間中の所定時間T0に、前記電流及び前記電圧に基づいて、複数の候補値(c1,c2,c3)のうち何れかを選択し、選択された候補値に関する前記電流及び前記電圧、又は前記関数の変化に基づいて、モータ8の特性パラメータを演算し、モータ8の停止電流を演算する。【選択図】 図8
