摘要:
A brake control device for a vehicle includes a master cylinder, a wheel cylinder, a brake pedal behavior simulator, a normally-open type electromagnetic valve, a normally-closed type electromagnetic valve, and a brake pressure control device. The brake pressure control device includes a pump, a reservoir, and two electromagnetic valves to increase and decrease wheel cylinder hydraulic pressure. When the brake pressure control device is normally operated, a hydraulic pressure in the wheel cylinder is controlled by the brake pressure control device. On the other hand, when the brake pressure control device malfunctions or is abnormally operating, the wheel cylinder hydraulic pressure is controlled by hydraulic pressure generated from the master cylinder. At least the normally-closed type electromagnetic valve is opened when the brake pedal is in the non-operational state.
