Patent ID: 7620487

Claim:
An engine torque control device comprising: a shifting control section configured to selectively disengage a clutch during a downshift operation to attain a neutral state of a shifting unit and engage the clutch to complete the downshift operation after an actual engine speed has been synchronized to a target speed of the downshift operation; and an engine output torque control section configured to selectively perform first and second feedback controls of an engine output torque from an engine during the downshift operation such that the actual engine speed approaches the target speed of the downshift operation, the engine output torque control section being further configured to switch the first feedback control to the second feedback control when a difference between the target speed and the actual engine speed is equal to or less than a specified value during the downshift operation, the second feedback control being different from the first feedback control, and the second feedback control being performed by at least a proportional control and a differential control to control the engine output torque from the engine during the downshift operation, the first feedback control being performed by control other than differential control prior to switching to the second feedback control.
