<p><P>PROBLEM TO BE SOLVED: To provide a control device for a vehicular automatic transmission, suppressing interference in learning of respective back pressure control and torque-up control of an accumulator in the case of speed change operation. <P>SOLUTION: This control device for the vehicular automatic transmission has the accumulators 104, 106, 108 for controlling hydraulic pressure supplied to a second clutch C2, a third clutch C3, and a third brake B3, makes the back pressure control controlling back pressure of the accumulators 104, 106, 108 in the case of the speed change operation, and also makes the torque-up control raising torque outputted from an engine 12. In this control device for the vehicular automatic transmission, it is decided whether the learning of the back pressure control is completed. When it is decided that the learning of the back pressure control is not completed, the torque-up control is not executed, and the learning of the back pressure control is executed. Thus, the interference of the learning of the respective back up pressure control and torque-up control is avoided. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
