Abstract

For controlling an internal combustion engine, the activation of an accelerator pedal is sensed and a setpoint value for the angle setting of the throttle valve is determined in dependence on the measured variable of an accelerator pedal value signal transmitter and on further influencing variables from a vehicle movement dynamics control device, a cruise controller device and/or a gearbox control device. The setpoint value is restricted to an unthrottled throttle valve angle of an unthrottled state of the engine. An over travel of the throttle valve, which corresponds to an adjustment range of the throttle valve between the unthrottled throttle valve angle and a fully open setting of the throttle valve is used, in dependence on the measured variable and at least one of the influencing variables, to open the throttle valve beyond the unthrottled throttle valve angle.
