Abstract
An engine control apparatus of the present invention sets a target torque τe, when the save mode mis set as an engine mode, according to the formula:τe←TRQ*RATIO+TRQ*(−RATIO) Basic target torque TRQand TRQare set based on the engine speed Ne and the throttle opening-degree θacc and with reference to the normal mode map Mpand the power mode map Mprespectively. The correction factor RATIOis an addition rate which is set based on an accelerator opening-degree θacc and a vehicle speed V and with reference to a correction factor map Mr. The correction factor map Mrstores a correction factor RATIOnear 0 (although 1≧RATIO>0) when the vehicle speed V is low and the accelerator opening-degree θacc is high.
