摘要:A control apparatus and method are provided for controlling a torque of an
engine coupled to an input shaft of an automatic transmission during a shift by thatautomatic transmission. In that control, torque-down control by which the engine torqueis decreased by a predetermined amount is performed, a torque-restore control startingpoint at which time torque-restore control is to be started is determined during thetorque-down control, and the torque-restore control so as to gradually restore theengine torque to a value before the torque-down control was performed is started atthe torque-restore control starting point. The torque-restore control starting point isdetermined according to a dynamic model which simulates the behavior of the automatictransmission over time from the start of the torque-down control, and so that arotational speed of the input shaft of the automatic transmission at a target pointsubstantially matches a target speed. A map does not need not to be created toimplement this control.
