Engine torque control device, in particular during downshift
DRIVE
May 10, 2006
An engine torque control device is configured to reduce shift shock while shortening shift time and improving shift response in an engine (1) 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.
