自动变速器的控制装置和控制方法
摘要：
本发明提供一种自动变速器的控制装置和控制方法。所述控制装置包括：有级变速机构；动力的接通/断开状态判断单元；以及变速控制单元，其通过根据输入至所述有级变速机构的扭矩使所述第一接合部分离并且使所述第二接合部接合，来对所述有级变速机构进行变速控制，以达到目标转速。所述变速控制单元使所述第一接合部和所述第二接合部中的具有抑制所述有级变速机构的输入转速变化的作用的接合部接合，其中所述输入转速的变化是在对所述有级变速机构进行变速控制的过程中因切换动力的接通/断开状态时的动力的接通/断开状态的切换而产生的，并且使所述第一接合部和所述第二接合部中的另一个接合部分离。
摘要（英）：

A control apparatus for an automatic transmission includes a stepwise variable transmission mechanism; a power ON/OFF state judging section; and a shift control section configured to control the stepwise variable transmission mechanism to a target rotational speed by disengaging the first engagement portion and engaging the second engagement portion in accordance with a torque inputted to the stepwise variable transmission mechanism, the shift control section being configured to engage one of the first engagement portion and the second engagement portion which has a function to suppress a variation of an input rotational speed of the stepwise variable transmission mechanism which is generated by a switching of the power ON/OFF state when the power ON/OFF state is switched at the shift control of the stepwise variable transmission mechanism, and to disengage the other of the first engagement portion and the second engagement portion.
