Abstract
A method for calibrating a drive of a throttle valve of an internal combustion engine of a motor vehicle includes detecting whether the internal combustion engine is currently running or is not running. The method further includes activating the drive to displace the throttle valve into a target position if it is detected that the internal combustion engine is currently not running. The method further includes calibrating a characteristic at the target position. A correlation between a rotor position of the drive and an output voltage of a throttle valve angle transducer follows a characteristic.
