ABSTRACT:
An ECU executes a program including: detecting the engine speed NE and the current KL (S1010, S1020) when the ISC learning control is started (“YES” in S1000); changing the ignition efficiency so that the NE and the output torque are kept unchanged even when the throttle valve opening amount changes (S1030); calculating the target torque by multiplying the ISC target torque by the ignition efficiency (S1040); calculating the target KL based on the target torque, the NE and the MBT (S1050); calculating the throttle valve opening amount based on the target KL (S1060); calculating the target ignition timing based on the NE, the current KL and the target torque (S1070); and controlling an engine using the calculated throttle valve opening amount, ignition timing and fuel injection amount (S1080).
