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; engagement start determining means (steps S2 †’ S3 †’ S4); and determination inhibit means (steps S2 †’ S5 †’ S6). The engagement start determining means 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 means inhibits the engagement start determination in a case where a switching from an HEV mode to an EV mode occurs in order to prevent an erroneous determination that the variation of the load which occurs due to the switching from HEV mode to the EV mode to the engagement start of the frictional engagement element.
