摘要： An engine ECU executes a program including the step of calculating a correlation coefficient K by dividing the sum SDS(I) of respective absolute values DS(I), which are each a difference between a magnitude in an engine vibration waveform and a magnitude in a knock waveform model for every crank angle, by an area S corresponding to magnitudes equal to or larger than a positive reference value in the knock waveform model (S110), and the step of determining whether or not knocking has occurred based on the correlation coefficient (S116, S120).

摘要： An engine ECU executes a program that includes the steps of: calculating 15-degrees integrated value integrating vibration intensity for each of six crank angle ranges (S110); detecting an amount of change in the 15-degrees integrated value between ignition cycles (S112); specifying two ranges having larger amounts of change (S114); specifying a crank angle having intensity larger than that of a neighboring crank angle in a search range determined to be the same as the specified ranges (S116); calculating a coefficient of correlation K corresponding to a difference between a vibration waveform and a knock waveform model (S122) while the specified crank angle is matched with a timing at which intensity peaks in the knock waveform model; and, if the coefficient of correlation K is larger than a threshold value K(0) (YES at S126), determining that knock has occurred (S128).

摘要： A motor current is estimated based on a target motor speed, an actual motor speed, and an engine speed. When the estimated motor current exceeds a predetermined value equivalent to a heat limiting current value, a variation (motor speed F/B amount) of the target motor speed outputted to an EDU (31) from an ECU (30) is restricted so that the motor current was restricted and heat generation in motor (26) is restricted. In consideration of a deterioration of responsivity of the variable valve timing control due to restriction of the motor current during execution of motor current restriction processing, an existence of the abnormalities of variable valve timing controller (18) is determined based on a deviation of the target camshaft phase and the actual camshaft phase.

摘要： An engine ECU executes a program including the steps of: calculating a coefficient of correlation K in accordance with a result of comparing a waveform of a vibration of a frequency band including a resonance frequency of an engine with a knock waveform model previously created as a waveform of a vibration caused when the engine knocks (S112); calculating a knock intensity N from an intensity of a vibration of a frequency band excluding the resonance frequency of the engine (S114); if knock intensity N is larger than a reference value and coefficient of correlation K is larger than a threshold value (YES at S116), determining that the engine knocks (S118); and if knock intensity N is smaller than the reference value and/or coefficient of correlation K is smaller than the threshold value, determining that the engine does not knock (S122).
