    • An ignition timing control apparatus and method for an internal combustion engine, and an engine control unit are provided for more rapidly and effectively restraining knocking as the entire internal combustion engine, and extending the lifetime of the internal combustion engine. The ignition timing control apparatus comprising an ECU. The ECU determines a basic ignition timing on a cylinder-by-cylinder basis, calculates a knock intensity on a cylinder-by-cylinder bases based on a detected signal of a cylinder inner pressure sensor, and updates a correction coefficient learning value for a corresponding cylinder when the knock intensity is larger than a predetermined first determination value and is smaller than a predetermined second determination value larger than the predetermined first determination value, and updates the knock intensities for all the cylinders when the one knock intensity parameter is equal to or larger than the predetermined second determination value. Then, the ECU calculates a knock correction term on a cylinder-by-cylinder basis in accordance with the correction coefficient learning value, and corrects the basic ignition timing with the knock correction term, thereby determining an ignition timing on a cylinder-by-cylinder basis.
