Claim:
1. A method for carrying out a reference measurement on a sensor of an internal combustion engine of a motor vehicle during an overrun phase of the internal combustion engine, the sensor requiring a reference measurement having a minimum time duration to ensure operability, the method comprising: receiving, by an engine control unit of the motor vehicle, at least one data signal including route data of the motor vehicle, the route data including a route to be traveled by the vehicle and a topology along the route; predicting, by the engine control unit, a future overrun phase of the internal combustion engine and a duration of the overrun phase based on the topology of the route to be traveled by the vehicle of the route data; generating, by the engine control unit, an authorization signal to control performing of a reference measurement by the sensor conditional upon the predicted duration of the overrun phase being longer than the minimum time duration required to carry out the reference measurement completely; and controlling, by the engine control unit, the internal combustion engine and sensor to perform the reference measurement in response to the authorization signal.
