Abstract
In a method for determining an output torque in order to prevent pedal play in a gas pedal assigned to a combustion engine, a correction torque Muffset is calculated in this respect, which is dependent on the activation speed Nact of the idling regulator, the current speed, and the idling torque MIS calculated by the idling regulator.

A method for determining an output torque in order to prevent pedal play in a gas pedal assigned to a combustion engine, comprising the steps of:
- calculating a second torque for a stable idling speed corresponding in particular to the operating state of the combustion engine,
- measuring the current speed of the combustion engine,
- forming a difference from a further speed and the idling speed, which forms the denominator of the quotient, wherein the multiplication of the quotient by the second torque produces a first torque.
A device for determining an output torque comprising:
- a speed sensor for measuring the current speed of a combustion engine,
- an idling regulator for calculating a second torque, to which the speed sensor is connected, and
- a correction unit for calculating a first torque, to which the output of the idling regulator is connected, and for forming a first difference from a further speed and the current speed, and a second difference from the further speed and an idling speed dependent on the second torque, wherein the correction unit calculates a quotient from the first and second differentials, and wherein the multiplication of the quotient by the second torque is provided at the output of the correction unit.
A device for determining an output torque comprising:
- means for calculating a second torque for a stable idling speed corresponding in particular to the operating state of the combustion engine,
- means for measuring the current speed of the combustion engine, and
- means for forming a difference from a further speed and the idling speed, which forms the denominator of the quotient, wherein the multiplication of the quotient by the second torque produces a first torque.
