Abstract:
1. An electric parking brake control device that controls an electric actuator that drives an electric parking brake, wherein the electric parking brake control device performs control to reach a lock position, a release position and a standby position between the lock position and the release position, wherein: in the lock position, the electric actuator is actuated, a friction-applying member is thereby pressed against a friction-applied member by the electric parking brake 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 electric parking brake is not actuated; and in the standby position, a transition to the lock position is performed in a shorter time than when the electric parking brake is actuated from the release position by the actuation of the electric actuator, the electric parking brake control device controls, when a starting operation to start moving a vehicle is performed, the electric actuator such that the standby position is reached, the electric actuator generates a brake force by causing a nut to come in contact with a piston such that the friction-applying member is pressed against the friction-applied member, and the standby position is a position at which a brake force of the electric parking brake is not generated, and a clearance between the piston and the nut at the standby position is smaller than a clearance between the piston and the nut at the release position.
