<P>PROBLEM TO BE SOLVED: To shorten the time required for determining the end of engagement as much as possible when determining the end of engagement of an engagement side friction engaging device based on rotational speed of a turbine to end speed-change control. <P>SOLUTION: Since the end of engagement is determined by the number of determination Noffon being smaller than the number of determination Non of usual power ON down-shift when power is turned ON during speed-change of 6 to 5 down-shift of power OFF, speed is further changed to a target second speed gear stage after speed is once changed to a fourth speed gear stage, and the end of shift of 5 to 4 down-shift is determined, speed-change time can be shortened while preventing erroneous determination, the time for remaining at the fourth speed gear stage being a relay gear stage is shortened, the second speed gear stage is achieved early, and excellent acceleration responsiveness is obtained. <P>COPYRIGHT: (C)2007,JPO&INPIT |
