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.
