ABSTRACT:
The invention relates to a method for determining the fill quantity of an operating medium, in particular of the engine oil in a motor vehicle having a reservoir container of the operating medium and having a data processing device for determining the fill quantity of the operating medium. A fill level sensor for sensing the fill level is arranged in the reservoir container for the operating medium. In order to determine the fill level of the operating medium, operating states of the vehicle such as the temperature of the operating medium and the engine speed are also sensed. According to the invention, a characteristic variable for the engine load, for example the position of the accelerator pedal, the throttle valve position or the torque on the drive train are sensed. The fill quantity of the operating medium is determined from the sensed data by a data processing device.
