摘要： An electro-mechanical brake achieves a safe traveling and braking with a high accuracy device for detecting a piston position at which a brake pad and a disk rotor contact each other. A pad contact position detecting device in which an electric circuit is not formed to prevent an electric current from flowing therethrough when a pad pressing force is not generated and the electric circuit is formed to enable the electric current to flow therethrough when the pad pressing force is generated is applied to the electro-mechanical brake. A pad contact position can thereby be detected accurately.

摘要： Provided is an electric brake capable of accurately estimating the brake pad temperature and securing a sufficient braking force and response. An electric brake has a disc rotor rotating with a wheel, an actuator for rectilinearly actuating a piston in the axial direction of the disc rotor by using an electric motor, a drive controller for controlling the drive of the actuator, a brake pad pressed by the piston to give a frictional resistance to the disc rotor in the direction of rotation, and a braking start position detector for detecting a braking start position of the piston where the disc rotor is brought into contact with the brake pad. The drive controller stores the braking start position detected by the braking start position detector as the maximum braking start position. When the braking start position shifts in the pressing force-increasing direction, the drive controller updates the value stored as the maximum braking-start position.

摘要： A motor-driven disk brake system is capable of preventing a pressing member from moving beyond a predetermined position at a time of stopping a motor. When a command for system termination is issued, motor current is reduced intermittently, which correspondingly reduces a motor displacement gradually such that a return force is spent gradually on a return displacement of a motor and a piston, thereby preventing a rotational speed of a rotor from increasing. A large accelerated backward movement of the motor and the piston beyond a predetermined position due to inertia is thereby prevented, because the return force does not act all at once during the return displacement of the motor and the piston. Accordingly, the piston is stopped near a standby position of non-braking state before system termination. As a result, a next activation of the motor-driven disk brake system can be conducted promptly.
摘要翻译：电动盘式制动系统能够在停止电动机时防止按压构件移动超过预定位置。当发出系统终止命令时，电动机电流间歇性地减小，这相应地减小了电动机的位移，使得在马达和活塞的返回位移上逐渐地消耗一个返回力，从而防止了转子的旋转速度增加。因此，由于在马达和活塞的返回位置期间马达和活塞不会一次作用，所以马达和活塞因惯性而超过预定位置的大的加速向后运动被阻止。因此，在系统终止之前，活塞停止在非制动状态的待机位置附近。结果，可以及时地进行电动盘式制动系统的下次启动。
