ELECTRIC PARKING BRAKE CONTROL DEVICE, ELECTRIC PARKING BRAKE DEVICE AND CONTROL METHOD OF ELECTRIC PARKING BRAKE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric parking brake control device or the like capable of preventing the lowering of target tensile force and achieving power saving such as the miniaturization of an actuator to wind up a cable, etc.;SOLUTION: This electric parking brake control device 9 to control an electric PKB actuator 30 to wind up the cables 34R, 34L connected to parking brake units 35R, 35L of a wheel, respectively, and the brake actuator 10 to control braking pressure by a service brake of the wheel has a pressure boosting control means 9a to boost the braking pressure to a prescribed value by controlling the brake actuator 10 when a tensile force is lowered to a value smaller than target tensile force after winding up the cable until it reaches the prescribed target tensile force and a tensile force increase control means 9b to wind up the cable until it reaches the tensile force larger than the target tensile force by controlling the electric PKB actuator 30 after boosting it by the pressure boosting control means.;COPYRIGHT: (C)2008,JPO&INPIT
