Abstract:
Brake pressure control system, comprising:a master cylinder which is connected by way of a brake line to at least one wheel brake so that brake pressure is built up when the master cylinder is operated,a low pressure accumulator into which pressure fluid is discharged for reducing the pressure in the wheel brake,a pump which is connected with its suction side to the low pressure accumulator and with its pressure side to the brake line,a device for sensing the actuating condition of the master cylinder which device is used to actuate the pump for emptying the low pressure accumulator when the master cylinder is released and brake pressure control took place, wherein the rotational speed of the pump is monitored in an emptying period, and the emptying period is terminated on command of the rotational speed signal by disconnection of the pump.
