Control device for automatic transmission

摘要

There is provided a control apparatus for an automatic transmission AT into which driving forces from driving sources including an engine Eng and a motor/generator MG are inputted. The control apparatus includes: a second brake B2 engaged in a D range; an engagement start determining section (steps S2→S3→S4); and a determination inhibit section (steps S2→S5→S6). The engagement start determining section determines that second brake B2 has started the engagement in a case where a load of the motor/generator MG is increased by a predetermined quantity during the revolution number control and when the D range is selected and second brake B2 in the release state is engaged. The determination inhibit section inhibits the engagement start determination in a case where a switching from an HEV mode to an EV mode occurs.

1. A control apparatus for an automatic transmission into which driving forces from driving sources including an engine and a motor are inputted, the control apparatus comprising:
a frictional engagement element engaged in a traveling range; engagement start determining means for determining that the frictional engagement element has started the engagement in a case where a load of the motor is increased by a predetermined quantity, during a revolution number control in which a revolution number of an input shaft of the automatic transmission is controlled to a predetermined target revolution number and when the traveling range is selected and the frictional engagement element in a release state is engaged; and determination inhibit means for inhibiting the determination by the engagement start determining means before the determination that the frictional engagement element has started the engagement and in a case where a switching from an HEV mode in which the driving forces from the engine and the motor are inputted to the input shaft to an EV mode in which the driving force of only the motor is inputted to the input shaft occurs.
