ABSTRACT:
A controlled variable and a target in each of a variable valve event and lift control apparatus and a variable valve timing control apparatus are input, to calculate target opening timing of an intake valve corresponding to the target and also to calculate actual opening timing of the intake valve corresponding to the controlled variable, to correct ignition timing based on a deviation between the target opening timing and the actual opening timing.
