摘要： 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.

摘要： Die Erfindung bezieht sich auf ein Verfahren zur Bestimmung der Menge einer in einem weitgehend abgeschlossenen System eines Kraftfahrzeuges befindlichen Flüssigkeit, deren Füllstand im System fahrzustandsabhängig schwankt. Bei bekannten Verfahren dieser Art zur Motorölmengenbestimmung erfolgt die Ölmengenbestimmung durch Füllstandsmessungen bei stehendem Fahrzeug und abgestelltem Motor.
Es wird vorgeschlagen, im Fahrbetrieb fahrzustandsindikative Größen zu erfassen, daraus den momentanen Fahrzustand zu ermitteln und wenigstens während ausgewählter Fahrzustände im Fahrbetrieb laufend den Füllstand zu erfassen sowie daraus anhand einer vorgegebenen Abhängigkeit der Flüssigkeitsmenge vom Fahrzustand und vom Füllstand die momentane Füllmenge zu bestimmen. Dies erlaubt beispielsweise eine Motorölmengenüberwachung im laufenden Fahrbetrieb.
Verwendung in Kraftfahrzeugen.

摘要： A method for warning of insufficient engine oil for a vehicle includes: determining, by a controller, whether conditions for determining that the vehicle has insufficient engine oil are satisfied, after an engine of the vehicle is started; determining, by the controller, whether an integrated value obtained by integrating a difference between a target operating value and an actual operating value of a hydraulic continuously variable valve timing (CVVT) device included in the engine within an operating time period of the hydraulic CVVT device is equal to or greater than a reference difference value, when the conditions for determining whether the vehicle has insufficient engine oil are satisfied; and determining, by the controller, that the vehicle has insufficient engine oil based on counting information on the number of times the integrated value, obtained by integrating the difference between the target operating value and the actual operating value, is equal to or greater than the reference difference value.

摘要： Methods and systems are provided for filtering an oil dilution amount based on a current value of the oil dilution amount. In one example, filtering the oil dilution amount may include decreasing a sensitivity of filtering at lower oil dilution below a threshold; otherwise, increasing the sensitivity of filtering. The sensitivity of the filtering may be decreased by implementing a larger time constant, while the sensitivity of the filtering may be increased by implementing a smaller time constant.

The oil supply channel includes a pump downstream oil channel connecting the operating chamber with the filter and a control oil channel branched from the pump downstream oil channel and coupled to the control oil-pressure chamber. The device also includes a control valve provided in the control oil channel. A starting control is performed in which the valve opening is set larger than a predetermined rate before the pump starts driving and set smaller than the predetermined rate after the pump starts driving.
