Abstract

In order to improve a method for controlling the speed of an electromotor-driven pump of a hydraulic power steering device of a motor vehicle as a function of the steering speed, so that the overall efficiency of the system is optimized in a simple manner; it is proposed that the required volume flow of hydraulic fluid, calculated according to a determined steering speed, is increased up to a maximum by an additional correction factor that takes into account the overall efficiency of the system, in order to use the result to calculate and to adjust the set speed of the pump.
