Title:
ELECTRIC BRAKE, AND CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/066645
Kind Code:
A1
Abstract:
This electric brake is provided with: a brake mechanism which, on the basis of a brake demand, transmits a thrust force generated by means of the drive of an electric motor to a piston which moves a brake pad that is pressed against a disk rotor; and a rear electric brake ECU which controls the drive of the electric motor, and moves the piston to a prescribed clearance position in which a clearance between the brake pad and the disk rotor in a non-braking state is a prescribed amount. The rear electric brake ECU drives the electric motor in such a way that the time from the brake demand until the brake pad starts to press the disk rotor is a prescribed time period, regardless of the position of the piston when the brake demand is generated.
