Claims (7)
前記ケーシングと前記入力部材との間に設けられて前記入力部材が待機状態にあるか否かを検出する待機状態検出手段を有することを特徴とする電動倍力装置。 The brake pedal includes an input member that moves forward and backward by operation of a brake pedal, an assist member that is movably disposed in accordance with the advancement and retraction of the input member, and an electric motor that moves the assist member forward and backward. In the electric booster for providing an input stroke detection means for detecting the amount of movement of the input member by the control means, the control means controls the electric motor based on the detection value of the input stroke detection means,
An electric booster comprising standby state detection means provided between the casing and the input member for detecting whether or not the input member is in a standby state.
前記制御手段は、前記待機状態検出手段により前記入力部材が非待機状態にあることが検出されたとき、前記入力ストローク検出手段の検出値に代えて、当該入力ストローク検出手段の検出値から前記ゼロ点データを減算して得られる値に相当するゼロ点補正検出値を前記電動モータの制御に用いることを特徴とする電動倍力装置。 The electric booster according to claim 1, wherein when the standby state detecting means detects that the input member is in a standby state, the zero point of the input stroke detecting means is stored as zero point data, Storage means for updating and storing the zero point data each time the standby state detecting means detects that the input member is in a standby state during the operation period of the control means;
When the standby state detection unit detects that the input member is in a non-standby state, the control unit replaces the detection value of the input stroke detection unit with the detection value of the input stroke detection unit. An electric booster characterized in that a zero point correction detection value corresponding to a value obtained by subtracting point data is used for controlling the electric motor.
ドライバが前記ブレーキペダルを踏んでいないと判断するための信号を出力する待機状態検出手段を有することを特徴とする電動倍力装置。An electric booster comprising standby state detection means for outputting a signal for determining that the driver is not stepping on the brake pedal.
