Abstract
An EPB control device controlling an electric actuator driving an EPB, wherein the device performs control to reach a lock position, a release position and a standby position between the lock position and the release position. In the lock position, a friction-applying member is thereby pressed against a friction-applied member by the EPB by actuating the electric actuator and a predetermined braking force is generated. In the release position, the friction-applying member is separated from the friction-applied member when the EPB is not actuated. In the standby position, a transition to the lock position is performed in a shorter time than when the EPB is actuated from the release position by the actuation of the electric actuator. The device controls, when a starting operation to start moving a vehicle is performed, the electric actuator such that the standby position is reached.
