Beschreibung
Zusammenfassung:	To detect tooth chipping of a toothed belt.SOLUTION: An electronic control unit compares an actual measurement value that is frequency of oil pressure pulsation calculated on the basis of time variation of hydraulic pressure detected by a hydraulic sensor with a theoretical value that is frequency of oil pressure pulsation calculated on the basis of rotational frequency of a crank shaft and the number of teeth of an inner rotor (Step S150). When the actual measurement value is deviated from the theoretical value, the electronic control unit detects an abnormality of a toothed belt (Step S170).SELECTED DRAWING: Figure 3 【課題】歯付ベルトの歯欠けを検知する。【解決手段】電子制御ユニットは、油圧センサが検出する油圧の時間変動に基づいて算出されるオイルの圧力脈動の周波数である実測値と、クランクシャフトの回転数及びインナロータの歯の数に基づいて算出されるオイルの圧力脈動の周波数である理論値とを比較する（ステップＳ１５０）。電子制御ユニットは、実測値が理論値からずれている場合に、歯付きベルトの異常を検出する（ステップＳ１７０）。【選択図】図３
