ABSTRACT:
A braking system of a motor vehicle including an accumulator, being coupled to a to motor-driven pump, for accumulating a hydraulic pressure which is supplied to a braking device to brake a wheel of the motor vehicle and a control valve provided between the accumulator and the braking device for regulating the hydraulic pressure to be applied from the accumulator to the braking device. Also included in the braking system is a control unit for controlling the control valve in accordance with the condition of the wheel. The control unit controls the motor-driven pump on the basis of the control time of the control valve.
