초록

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 mo...

청구항

[ What is claimed is:] [1.] 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:sensing driving-condition-indicative quantities in a driving operation of the motor vehicle, including a rotational engine speed;determining momentary driving conditions based on said sensed driving-condition-indicative quantities in the driving operation of the motor ve...
