Abstract:
First target torque of an engine is set based on a driver's operation, a vehicle behavior, and a request for shifting gears of an automatic transmission. The engine is controlled such that the difference between the first target torque and the actual output torque of the engine is reduced. Detection torque is calculated from an operation state of the engine. In consideration of dead time in control of the engine, calculation torque is calculated from the first target torque. In addition, first lookahead torque with the dead time in the engine being removed is calculated by feedback-correcting the first target torque according to an error e between the detection torque and the calculation torque.
