摘要:
An engine ECU executes a program including: the step (S222) of increasing a determination value V(J) by a correction amount A(3) if the number of knock intensities N not lower than the determination value V(J) is not smaller than a threshold value B(1) (YES at S220) among knock intensities N of a plurality of predetermined number of continuous ignition cycles; and the step (S232) of increasing the determination value V(J) by a correction amount A(5) if the number of knock intensities N not smaller than the determination value V(J) is not smaller than a threshold value B(3) (YES at S230), among knock intensities N of a plurality of ignition cycles satisfying the condition that a coefficient of correlation K calculated by comparing a vibration waveform and a knock waveform model is not smaller than a threshold value K(1), of the knock intensities of a plurality of predetermined continuous ignition cycles.
