ABSTRACT:
An engine torque control device is configured to reduce shift shock while shortening shift time and improving shift response in an engine equipped with a shifting unit. In the engine torque control device engine output torque is subjected to feedback control so that the engine speed will be the target speed (synchronizing speed) after a downshift. The feedback control includes at least a proportional control and a differential control. The differential control is halted until the difference between the synchronizing speed and the actual engine speed is equal to or less than a specified value. Differential control is only performed at or below this specified value.
