Patent ID: 7300381

Claim:
A method for controlling output torque of an internal combustion engine during a torque reduction phase of a gearshift event such torque being controlled by an electronically controlled throttle valve disposed in an engine intake, such method comprising: forecasting a throttle valve position to achieve a desired torque reduction in response to a signal indicating initiation of the gearshift event; actuating the throttle valve to position the throttle valve to said forecasted throttle valve position; determining a transmission requested torque trajectory with a transmission control unit coupled to said transmission; and adjusting fast actuators coupled to the engine to have the output torque match a torque trajectory during the torque reduction phase such that the torque trajectory and the requested torque trajectory are substantially the same during most of the torque reduction phase of the gearshift event wherein a fast actuator is an actuator in which the effect of an adjustment in said actuator is realized in a next engine combustion event.
