To provide a motor-driven brake device which generates a high braking force in braking during vehicle travel and is also capable of performing mechanical braking.SOLUTION: A motor-driven brake device (1) comprises an ECU (100) for selectively executing: first brake control in which a liquid path (60) is cut off by a first solenoid valve (54); an input piston (25) is then driven by an electric motor (22) in a direction where a pad (30) approaches a disc (3); and the pad (30) is pressed to the disc (3); and second brake control in which the liquid path (60) is opened by the first solenoid valve (54); the input piston (25) is then driven by the electric motor (22) in the direction where the pad (30) approaches the disc (3); and the pad (30) is pushed onto the disc (3).SELECTED DRAWING: Figure 1
【課題】車両走行中の制動では高い制動力を発生させると共に、機械的な制動を行うことも可能な電動制動装置を実現する。【解決手段】電動制動装置(1)は、第1電磁弁(54)により液路(60)を遮断させた上で、パッド(30)がディスク(3)に近づく方向に、電気モータ(22)により入力ピストン(25)を駆動させて、パッド(30)をディスク(3)に押し付ける第1制動制御と、第1電磁弁(54)により液路(60)を開放させた上で、パッド(30)がディスク(3)に近づく方向に、電気モータ(22)により入力ピストン(25)を駆動させて、パッド(30)をディスク(3)に押し当てる第2制動制御とを、選択的に実行するECU(100)、を備える。【選択図】図1
