Title:
ELECTRIC BRAKE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/132019
Kind Code:
A1
Abstract:
Provided is an electric brake device which can improve vehicle braking feeling and can also reduce operating sounds. A control device (2) of this electric brake device (1) has a brake release command calculation unit (26) which, when a brake force command value is zero or a brake release request to release the brake force is recognized, controls the angle of an electric motor (4) so that the angle follows the motor angle command value that provides a predetermined clearance between a friction member (9) and a brake rotor (8). This brake release command calculation unit (26) has a function allowing the angle of the electric motor (4) to overshoot the motor angle command value and then track the motor angle command value when the brake force is brought to zero from a state in which brake force has been exhibited.
