In the present invention, a brake device is equipped with: differential pressure control valves; pressure adjusting units which are connected to the differential pressure control valves through liquid passages; and a control device which controls the WC pressure Pwc in wheel cylinders by operating the differential pressure control valves and the pressure adjusting units. When predetermined suppression control permission conditions are satisfied while both the supply pumps of the pressure adjusting units and the differential pressure control valves are in operation, the control device performs self-excited vibration suppression control over the differential pressure control valves, the self-excited vibration suppression control being carried out in such a manner that a valve element separated from a valve seat is caused to abut on the valve seat, and, upon abutting on the valve seat, the valve element is separated from the valve seat.

Hydraulic control device for vehicles

Each of a plurality of electric brake devices corresponds to one of a plurality of wheels and includes a motor. A brake ECU, which controls the electric brake devices, determines whether there is an overheated motor of which the temperature T is greater than or equal to a first set threshold value Tth. Also, when there is only one overheated motor, the brake ECU reduces a current value Ix for the overheated motor at a more gradual gradient in the case where the temperature T of the overheated motor is low than in the case where the temperature is high.
