Abstract
An ECU executes a program including the steps of: starting monitoring the turbine revolution speed and the output shaft revolution speed when a direct shift is started (YES in S) (S); performing complete disengagement control on a disengagement element () (S), lowering control pressure of a disengagement element () to preliminarily fixed control pressure (S); starting engagement control on an engagement element () when a set time period Is () passes (YES in S) (S); performing complete disengagement control on the disengagement element () when a set time period Is () passes (YES in S) (S); and starting the engagement control on an engagement element () when turbine revolution speed NT is equal to or larger than (the synchronous revolution speed of a gear after a shift—a set value Ns) (YES in. S) (S).
