Abstract: A PCM comprises a basic target torque-deciding part for deciding a basic target torque, based on a driving state of a vehicle including an accelerator pedal operation state, a torque reduction amount-deciding part for deciding a torque reduction amount, based on a driving state of the vehicle other than the accelerator pedal operation state, a final target torque-deciding part for deciding a final target torque, based on the decided basic target torque and the decided torque reduction amount, and an engine output control part for controlling an engine to cause the engine to output the decided final target torque, wherein the engine output control part is operable to prohibit switching of an operation mode of the engine from being performed simultaneously with control of the engine according to a change in the final target torque corresponding to a change in the torque reduction amount.

Abstract: The engine control device comprises a basic target torque-deciding part for deciding a basic target torque based on a driving state of a vehicle, a torque reduction amount-deciding part for deciding a torque reduction amount based on a steering wheel operation state, an TCM for deciding a torque-down demand amount, based on a driving state of the vehicle other than the steering wheel operation state, and a final target torque-deciding part for deciding a final target torque, based on the decided basic target torque, the decided torque reduction amount and the decided torque-down demand amount, wherein the final target torque-deciding part is operable, when there is a torque-down demand, to restrict a change in the final target torque corresponding to a change in the torque reduction amount.
