Method and Control Unit for Calibrating a Drive of a Throttle Valve of an Internal Combustion Engine in a Motor Vehicle

A control unit for a motor vehicle, wherein the control unit is configured to perform a method, wherein a correlation between a rotor position of the drive and an output voltage of a throttle valve angle transducer follows a characteristic, the method including:

• detecting whether the internal combustion engine is running;
• and
• activating the drive to displace the throttle valve into a first target position and performing a first calibration of the characteristic at the first target position, if it is detected that the internal combustion engine is not running.

A computer program product, comprising computer-readable instructions that instruct the computer program product when run on a programmable control unit to perform a method, wherein a correlation between a rotor position of the drive and an output voltage of a throttle valve angle transducer follows a characteristic, the method including:

• detecting whether the internal combustion engine is running;
• and
• activating the drive to displace the throttle valve into a first target position and performing a first calibration of the characteristic at the first target position, if it is detected that the internal combustion engine is not running.
