Abstract
During switching of an input rotation transmission mechanism, the actual engine rotational speed at the start of the switching and the speed changing ratio change amount owing to the switching operation are used as a basis for computing the target engine rotational speed of an engine and for computing the target speed changing ratio for an automatic transmission such that the rotational speed of automatic transmission on the side toward input rotation transmission mechanism nearly matches the rotational speed of input rotation transmission mechanism on the side toward automatic transmission, and shifting operation control for automatic transmission is executed in the opposite direction that is synchronized with the switching operation of input rotation transmission mechanism.
