    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： When changing gear, engagement side clutch coupling force of an automatic transmission (32) is controlled in response to an engagement side clutch coupling force control amount set in advance in an engagement side clutch coupling force control amount storage section (36). A disengagement side clutch coupling force control amount calculating block (40) has a physical model of the automatic transmission (32) internally. This disengagement side clutch coupling force control amount calculating block (40) then calculates disengagement side clutch coupling force control amount from a transmission input torque estimation value estimated by a transmission input torque estimation block (34), a running resistance estimation value from a running resistance estimation block (38) and engagement side clutch coupling force control amount using the physical model, and controls the automatic transmission (32) using the calculated disengagement side clutch coupling force control amount. Since disengagement side clutch coupling force control amount is calculated using a physical model, it is easy to adjust the disengagement side clutch coupling amount. It is also suitable to control engine torque at the time of gear shift, and this engine torque can also be determined using a physical equation.

    摘要： A deviation between a target value of a quantity of state and an actual value of the quantity of state that is caused to follow the target value or a time-integral of the deviation is filtered. Based on the filtered value, a switching surface &sgr; is calculated. Based on a value of the switching surface &sgr;, a control input value u is outputted. The filter is set through comparison in Bode diagrams between a design model of a control system based on an ordinary sliding mode control method and a characteristic variation model of the control system, and by performing compensation in such a direction as to cancel out the variation. The filtering process makes it possible to properly control the control system having a dead time by the sliding mode control method.

    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.

    摘要翻译： 在控制对象的增益被调查的情况下，控制对象的特征变化在功能上由参数θ表示，该参数θ在0和1的值之间变化。 识别信号的频率被设定为增益差变大的频率。 识别信号的幅度被设定为使得控制对象的输出的变化幅度小于或等于预定值。 由于相对于参数的输入/输出特性更敏感，因此识别精度提高，所以由这种设定装置设定的识别信号具有高识别精度。 此外，由于基于控制对象的输出的变化宽度来设定识别信号的幅度，因此可以在不显着影响控制对象的输出的情况下进行识别。

    摘要： An instruction value Duty for bringing a slip rotation speed Nslip to a target rotation speed is feedback-controlled based on a difference e between the slip rotation speed Nslip and the target rotation speed, and a weight &thgr; from a parameter map. Weights &thgr; are assigned individually to a plurality of models, each of which includes a group of parameters and which are used to form a control model that represents a slip control system. Based on a weight that is assigned to one of the plurality of models, a weight that is assigned to at least one model that is other than the one of the plurality of models is specified. Thus, the amount of calculation required can be reduced by estimating weights for the models including the groups of parameters, which contain parameters that are used to construct the control model, instead of directly estimating the control model-constructing parameters.
