A setpoint torque is determined from a torque factor, a maximum torque and a minimum torque. The torque factor is derived from a pedal value and a rotational speed. The maximum and minimum torques are determined as a function of the rotational speed, a loss torque and engine performance parameters. The loss torque is determined as a function of the rotational speed and the performance parameters.

Method for controlling an internal combustion engine

A method and device for controlling an internal combustion engine includes a pedal position transmitter which registers the pedal position of a gas pedal. An estimated value of a desired torque to be applied at a clutch is derived cyclically from the pedal position and at least one operating variable of the internal combustion engine. A set point of the desired torque is ascertained as a function of an estimated value of the desired torque. A change over time of the set point (TQ.sub.-- REQ.sub.-- EST) of the desired torque is limited to a predefined change value (AW) while the set point remains in a predefined value range about the zero value of the desired torque.
