Abstract
The invention relates to an electrohydraulic control system (1) for the actuation of at least one actuator (2-5), in particular a piston-cylinder assembly in a motor vehicle, having an assembly (7) comprising an electronic control unit (ECU), having an electric motor (8) which is activated by the electronic control unit (ECU) in order to drive a high pressure pump (9), and having a receiving body for receiving electrohydraulic valves (10-17), for receiving channels and for receiving the controllable high pressure pump (9) which is connected to a pressure transducer (27) and/or vessel (34) via a hydraulic connection (30, 31; 32, 33), and can also be connected to a pressure space of the actuator (2-5), in particular piston-cylinder assembly, wherein the electrohydraulic valves (10-17) and the electric motor (8) are networked to the electronic control unit (ECU), and wherein the electrohydraulic valves (10-17) are provided both for ventilating the high pressure pump (9) and for controlling the volume flow and/or pressure of the actuator (2-5).The core of the invention is considered to be using the same pairs of electrohydraulic valves (10-17) in an electrohydraulic control system (1) …
