Abstract
The invention provides a torque feedback shift control device for an engine control system including an engine, an engine torque controller, an automatic transmission for changing output speed of the engine, and a transmission controller for controlling gear shifting in the transmission. A target torque generator is provided for generating a signal indicative of a target torque pattern in shifting of the automatic transmission according to a shifting signal from the transmission controller. A drive shaft torque detector detects an output torque of the automatic transmission, and the engine controller performs feedback control of the engine torque so that the output torque detected by the drive shaft torque detector in downshifting of the automatic transmission follows up the target torque pattern.
