ABSTRACT:
In a method and apparatus for measuring and displaying the engine oil filling level in a vehicle having a filling level switch or sensor, measured values of the switch or sensor, in the form of determined time components, are summed to determine a state duration of a particular state of the engine oil filling level. The state duration is compared with predefined time limiting values of the respective state of the engine oil filling level. According to the invention, the length of the individual time components is determined as a function of driving-state-dependent parameters.
