Abstract

A circuit configuration for controlling engine torque transmitted to a roadway through driven wheels of a motor vehicle includes a device for wheel-selective slip value detection and for determining a representative wheel slip, a device for specifying a set-point slip, and an engine controller that takes a slip status into account. The engine controller is preceded by a regulator, to which a difference between the set-point slip and the representative wheel slip is supplied as a control difference. A feedback signal characterizing the current engine torque is sent from the engine controller to the regulator.
