Parking brake control device

A parking brake control device that controls a hydraulic pressure unit for braking wheels hydraulically and a parking brake device for braking the wheels by transmitting power of an electric motor to the wheels mechanically, the parking brake control device comprising:

• a hydraulic brake control unit configured to exercise a hydraulic brake control under which a brake is applied to the wheels by the hydraulic pressure unit, on condition that a signal is received from an actuation switch for actuating the parking brake device, while a vehicle is running;
• and
• a pressure decrease rate setting unit configured to set a rate of decrease of pressure in such a manner that when a pressure decrease control is exercised in a closing stage of the hydraulic brake control, the rate of decrease of pressure is set according to a closing condition satisfied upon entry into the closing stage of the hydraulic brake control,
• wherein if the closing condition is receipt of a request for cancellation of the hydraulic brake control as submitted by a driver's operation while the vehicle is running, the pressure decrease rate setting unit sets the rate of decrease of pressure at a first pressure decrease rate having a value greater than a minimum value thereof.
