A process for determining the quantity of a liquid situated in a largely closed system of a motor vehicle is provided. The filling level of the liquid in the system fluctuates as a function of the driving condition. In the case of a known process of this type for determining the engine oil quantity, the oil quantity determination takes place by filling level measurements while the vehicle is standing and the engine is switched off. The present process determines driving-condition-indicating quantities in the driving operation, determines therefrom the momentary driving condition, and, at least during selected driving conditions in the driving operation, continuously sense the filling level, as well as determines therefrom the momentary filling quantity via a given dependence of the liquid quantity on the driving condition and on the filling level. This permits, for example, a monitoring of the engine oil quantity in the continuous driving operation.
A process for determining an engine oil quantity of engine oil contained in a largely closed system of a motor vehicle, wherein a filling level of the engine oil in the system fluctuates as a function of a driving condition, the process comprising the steps of:
