摘要： A brake fluid pressure control device controls brake fluid pressures through control of fluid pressure control valves operated in accordance with control signals from, for example, a computer. Signal lines for supplying control signals to control circuits controlling coils of linear valve devices for some wheels (e.g., front-left and rear-right wheels) are connected to a brake ECU by a connector, and signal lines for supplying control signals to the control circuits controlling coils of linear valve devices for other wheels (e.g., front-right and rear-left wheels) are connected to the brake ECU by a different connector. Thus, even if one of the connectors starts operating abnormally, it is possible to supply control signals via the signal lines connected by the other connector and control linear valve devices for some of the wheels (e.g., a pair of diagonally located wheels).

摘要： An electric brake apparatus generates an appropriate brake force without unnecessarily consuming electric power. The electric brake apparatus has a brake actuator generating a brake force. The brake actuator uses a brake motor system including a brake motor as a power source. A motor current provided to the brake motor is generated under a normal control so as to generate a brake force required for a vehicle. The motor current generated under the normal control is reduced when the brake motor is overheated or when the vehicle is stopped for a long time.

摘要： A hydraulic wheel brake system including a plurality of brakes and a hydraulic brake controller. The brakes includes wheel cylinders corresponding respectively to each wheel. The hydraulic brake controller includes a pump device, and a pump and valve controller. At least one pump included in the pump device is reversible. By controlling the pump and valve controller the pump increases brake fluid pressure in the brake during braking and the brake fluid pressure is reduced through the pump when it is required to be reduced. The hydraulic brake controller has a normal-open solenoid valve between a reservoir and the brake. The normal-open solenoid valve allows the brake fluid to flow when an electric current is not supplied. The hydraulic brake controller has also a normal-close solenoid valve between the reservoir and the brake. The normal-close solenoid valve prevents the brake fluid from flowing when an electric current is not supplied.

摘要： Hydraulic pressure control apparatus wherein a pressure difference across a seating valve disposed in a fluid passage acts on a valve member for placing the seating valve in an open state, while an elastic member biases the valve member for placing the seating valve in a closed state, and a valve driving device operated with an electric current applied thereto generates a drive force acting on the valve member so as to open the seating valve. A control device for controlling the electric current includes a stepping controller for incrementing the amount of the electric current when the seating valve is operated from the closed state into the open state, such that an increment of the electric current decreases with an increase in the pressure difference. The hydraulic pressure control apparatus may be suitably used in a vehicle braking system, for controlling fluid pressure in wheel brake cylinder.

摘要： A brake control apparatus has first and second wheel cylinders; a master cylinder unit; first and second systems; a separation valve; a pressure control mechanism that controls the working fluid pressure transferred to at least one of the first and second wheel cylinders independently of the brake operation, and a brake ECU. The brake ECU generates a differential pressure across the separation valve by operating the pressure control mechanism when there is no brake operation while a running drive source of a vehicle is stopped to determine whether the separation valve has a leakage abnormality.
