ABSTRACT:
A method and system for controlling output torque of an internal combustion engine during a gearshift in an automatic shift manual transmission coupled to the engine is disclosed. The transmission includes a multiplicity of gears and a clutch actuated by a transmission control unit (TCU), which controls clutch disengagement, gear change, and clutch re-engagement. The engine includes an engine control unit in communication with the TCU. The method includes determining engine operator demanded engine torque; sending a signal to the engine control unit in response to actuation of the clutch; and, computing in the engine control unit in response to the sent clutch actuation signal and the determined engine operator demanded engine torque, a control signal for the engine, such engine, in response to such control signal changing engine torque during the gear change to substantially match demanded engine torque when the clutch is re-engaged.
