Abstract

The rotational speed of at least one drive motor of a motor vehicle is controlled by an electronic control system, wherein the differential rotational speed between a specified target rotational speed and an actual rotational speed of the drive motor is considered as a system value for determining the control parameters that influence the rotational speed control process. As an additional system value, the magnitude and direction of the differential rotational speed gradient are considered when determining the control parameters.
