Abstract

Electronic control of the supply pressure of the pump is suggested with respect to a hydraulic brake system which is used for brake slip control, traction slip control and further driving stability control operations. Means of action include, for example, the control or reduction of the motor current of the pump, electromagnetic closure of the suction valve of the pump or a brief change-over of the separating valve in the brake line.
