  "textContent": "A parking brake control device 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 includes a hydraulic brake control unit capable of exercising 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 pressure decrease rate according to a closing condition satisfied upon entry into the closing stage of the hydraulic brake control when a pressure decrease control is exercised in a closing stage of the hydraulic brake control.",
