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 apparatus for an electric vehicle which maintains the regenerative energy generated in a traction motor of each of wheels to be at a maximum. A hydraulic pressure brake and a regenerative brake are provided in the same brake apparatus. The hydraulic pressure brake generates a brake torque by providing a hydraulic pressure to a wheel cylinder of each wheel of the vehicle. The regenerative brake generates a brake torque by regeneration in a traction motor for each wheel. The brake torque to be provided is calculated for each wheel. A maximum regenerative energy is calculated for each wheel. A hydraulic pressure calculating unit calculates a hydraulic pressure to be provided to the wheel cylinder of each wheel based on the brake torque and the maximum regenerative energy so that the regenerative energy generated by the traction motor of each wheel becomes a maximum. The hydraulic pressure calculated by the hydraulic pressure calculating unit is provided to the wheel cylinder of a corresponding wheel by a hydraulic pressure control valve which generates the hydraulic pressure by reducing a master cylinder pressure.

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.
