    摘要: A control apparatus and method control a torque of an engine coupled to an input shaft of an automatic transmission during a shift by that automatic transmission. A torque-down control by which the engine torque is decreased by a predetermined amount is performed, a torque-restore control starting point at which time torque-restore control is to be started is determined, and the torque-restore control so as to gradually restore the engine torque to a value before the torque-down control was performed is started at the torque-restore control starting point. The torque-restore control starting point is determined according to a dynamic model which simulates behavior of the automatic transmission over time from start of the torque-down control, so that a rotational speed of the input shaft of the automatic transmission at a target point substantially matches a target speed.

    摘要: A characteristics change of a control object is functionally represented by a parameter &thgr; which varies between values of 0 and 1 as the gain of the control object is surveyed. The frequency of the identification signal is set at a frequency where the difference in gains becomes large. The amplitude of the identification signal is set so that the variation width of the output of the control object is less than or equal to a predetermined value. Because the identification accuracy improves where the input/output characteristics with respect to the parameter are more sensitive, the identification signal set by such a setting apparatus imparts high identification accuracy. Moreover, because the amplitude of the identification signal is set based on the variation width of the output of the control object, identification can be performed without significantly affecting the output of the control object.
