摘要:
A base engine torque generated with an estimated intake air amount is estimated. An engine torque is corrected by correcting an ignition timing based on a difference between a required engine torque and the base engine torque. A torque correction amount is calculated based on a correction amount of the ignition timing. An actual engine torque is estimated based on the calculated torque correction amount and the base engine torque. A permitted component driving torque is a difference between the actual engine torque and the required vehicle driving torque. A component is controlled based on the permitted component driving torque.
