Abstract: An electric parking brake device generates pressing force by pressing friction materials against a brake disc by causing a piston to move by motor operation. A control device executes: parking processing wherein the motor increases the pressing force to an initial pressing force higher than a lower-limit pressing force; and re-drive processing wherein the motor is driven and the pressing force increased at a re-drive time, which is a predetermined time after the end of execution of parking processing. During parking processing, the control device uses one among the initial pressing force and the predetermined time, in addition to a pressing force decrease characteristic corresponding to an assumed temperature set for use in calculation, as a basis to calculate the other of the initial pressing force and the predetermined time such that the pressing force becomes equal to or less than the lower-limit pressing force at the re-drive time.

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.

Abstract translation: 控制驱动EPB的电动执行器的EPB控制装置，其中，所述装置执行控制以达到锁定位置和释放位置之间的锁定位置，释放位置和待机位置。 在锁定位置，通过致动电致动器，摩擦施加构件被EPB压靠在摩擦施加构件上，并产生预定的制动力。 在释放位置时，当EPB未致动时，摩擦施加构件与摩擦施加构件分离。 在待机位置，与通过致动器的致动从EPB从释放位置致动的时间相比，在更短的时间内执行到锁定位置的转换。 当执行开始移动车辆的开始操作时，该装置控制到达到待机位置的电致动器。
