Zusammenfassung:	In an oil level detection system of an internal combustion engine having a filter to capture particulates in exhaust gas that is burned off by fuel supplied by post injection to be regenerated and having an oil level sensor installed in an oil pan, it is determined whether the engine is under a long idling state (S12) and if so, an estimated value of the engine oil level is calculated by correcting output of the oil level sensor by an evaporation amount correction factor (S14). Then, it is determined whether the level of the engine oil is sufficient by comparing the estimated value with a threshold value (S16 to S20). With this, it becomes possible to detect the oil shortage without delay.
