Abstract
The invention relates to an electrohydraulic control system () for the actuation of at least one actuator (-), in particular a piston-cylinder assembly in a motor vehicle, having an assembly () comprising an electronic control unit (ECU), having an electric motor () which is activated by the electronic control unit (ECU) in order to drive a high pressure pump (), and having a receiving body for receiving electrohydraulic valves (-), for receiving channels and for receiving the controllable high pressure pump () which is connected to a pressure transducer () and/or vessel () via a hydraulic connection (), and can also be connected to a pressure space of the actuator (-), in particular piston-cylinder assembly, wherein the electrohydraulic valves (-) and the electric motor () are networked to the electronic control unit (ECU), and wherein the electrohydraulic valves (-) are provided both for ventilating the high pressure pump () and for controlling the volume flow and/or pressure of the actuator (-). The core of the invention is considered to be using the same pairs of electrohydraulic valves (-) in an electrohydraulic control system () for ventilating the high pressure pump () and for controlling the pressure at the actuator (-).
