Abstract
An engine control device for controlling an engine based on a vehicle operating state is provided, that includes a basic target torque determinator for setting a vehicle target acceleration based on an accelerator pedal operation and determining a basic target engine torque based on the vehicle target acceleration, a torque reduction demand determinator for determining whether an engine torque reduction is demanded based on the vehicle operating state other than the accelerator pedal operation, a torque reduction amount determinator for determining an engine torque reduction amount according to the operating state when the torque reduction is demanded, a final target torque determinator for determining as a final target torque an engine torque calculated by subtracting the torque reduction amount from the basic target torque when the torque reduction is demanded, and an engine controller for controlling the engine so as to output the final target torque.
