    • 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 S100) (S102); performing complete disengagement control on a disengagement element (1) (S106), lowering control pressure of a disengagement element (2) to preliminarily fixed control pressure (S110); starting engagement control on an engagement element (1) when a set time period Is (1) passes (YES in S112) (S114); performing complete disengagement control on the disengagement element (2) when a set time period Is (2) passes (YES in S118) (S120); and starting the engagement control on an engagement element (2) 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 122) (S 124).
    • ECU执行程序,包括以下步骤:当开始直接换档时开始监测涡轮转速和输出轴转速(S100中为“是”)(S102); 对分离元件(1)执行完全脱离控制(S106),将分离元件(2)的控制压力降低到预先固定的控制压力(S110); 当设定时间段Is(1)通过时(S112中为“是”),对接合元件(1)开始接合控制(S114); 当设定时间段Is(2)通过时(S118为“是”),对分离元件(2)执行完全脱离控制(S120); 并且当涡轮转速NT等于或大于(变速后的档位的同期转速 - 设定值Ns)时,在接合元件(2)上开始接合控制(S122中的是)(S124 )。
