    摘要: A device and associated method for controlling ignition timing of an internal combustion engine are provided. By comparing a determination value and knock magnitude, determination of knocking is made, and ignition timing is advanced or retarded. The device includes an operation unit that sets a correction amount of the determination value to a value corresponding to a degree of change of the determination value over time. The operation unit calculates, at a first timing, a first value related to an average value of the determination values; and calculates, at a second timing later than the first timing, a second value related to the average value of the determination values. The degree of change of the determination value is calculated as a difference between the first value and the second value.

    摘要: An engine ECU executes a program including a step of, when it has temporarily been determined that knocking had occurred because of the presence of an integrated value greater than a product of the reference magnitude and coefficient Y among the integrated values of vibration in fourth frequency band D that includes first to third frequency bands A to C, calculating knock magnitude N using the integrated values in the synthesized waveform of first to third frequency bands A to C and correlation coefficient K calculated from a vibration waveform of fourth frequency band D. Based on a comparison between knock magnitude N and determination value V(KX), whether or not knocking has occurred is determined. If there is no integrated value greater than a product of the reference magnitude and coefficient Y, it is determined that knocking has not occurred.
