<P>PROBLEM TO BE SOLVED: To attain a controller that can accurately determine transition when the engagement state of a second engagement device is changed. <P>SOLUTION: The controller includes: an objective rotary speed difference derivation section 43 in which each of detection results of a first rotary speed detector 91 and a second rotary speed detector 92 is converted into a rotary speed when they are transmitted to a specific rotary member 60, on the basis of the transmission gear ratio of a transmission 13, and a difference between two rotary speeds obtained from the conversion is derived as an objective rotary speed difference; and a transition determination section 44 that executes at least either of first transition determination for determining a transition to a slip engagement state from a direct engagement state of a second engagement device CM on the basis of comparison of the objective rotary speed difference with difference rotary threshold, and second transition determination for determining a transition to the direct engagement state from the slip engagement state of the second engagement device CM. The transition determination section 44 sets the difference rotary threshold to different values according to the transmission gear ratio of the transmission 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
