ABSTRACT:
A process and a system for controlling an electrohydraulic pressure supply for an auxiliary power device of an automotive vehicle in which a hydraulic pump system is operated by means of an electric motor the speed of rotation of which is controlled by operating parameters. In order to operate the auxiliary power system with the least possible energy, the changes in speed of rotation which differ from a predetermined desired speed of rotation of the electric motor are recognized and levelled out. In order to operate the power-assisted system with the least possible energy, the switching of the electric motor (2) from stand-by operation to full-load operation, or vice versa, takes place as a function of the speed of rotation (n) of the electric motor (2).
