Abstract
An electric brake apparatus includes an electric actuator configured to actuate a brake mechanism according to an actuation request signal, and an actuator controller configured to control an operation of the electric actuator with use of a power source mounted at a vehicle to perform control of holding and a release of braking by the brake mechanism. When a system recovers and the actuator controller detects that the control of the holding or the release has been interrupted with an uncompleted control state since system down occurred in the middle of the control of the holding or the release of the braking by the brake mechanism, the actuator controller maintains the interrupted state until a new actuation request signal is issued, and controls the operation of the electric actuator according to the content of the new actuation request signal.
