METHOD AND DEVICE FOR CONTROL IGNITION TIMING THROUGH KNOCK CONTROL IN AN INTERNAL COMBUSTION ENGINE |
摘要 |
An engine ECU executes a program including: determining whether or not a condition for stopping knocking determination is satisfied; setting a flag of stopping correction of a determination value to "ON"; calculating a knock determination level based on the extracted magnitude value; and when the correction stop flag is not "ON", decreasing or increasing the determination value in accordance with a knock proportion KC that is a proportion of magnitude values greater than the knock determination level. The knock determination level is calculated even when the correction stop flag is "ON".
