A coupling device including an engagement element provided on each of first and second elements and having a plurality of teeth, and a movable engagement member having a plurality of teeth meshing with the plurality of teeth of both engagement elements. , The first element and the second element are connected easily and smoothly. In the hybrid vehicle 20, for example, the movable engagement member EM2 is engaged with only the engagement portion 46e of the first motor shaft 46 while the movable engagement member EM2 is engaged with the engagement portion 46e and the second gear. When the first motor shaft 46 and the second gear 62a are coupled by engaging with both the engaging portions 62e of 62a, the number of rotations of the first motor shaft 46 with respect to the number of rotations of the second gear 62a. The motor MG1 is controlled so that the deviation matches the predetermined target rotational speed deviation, and the movable engagement member EM2 moves toward the engaging portion 62e only for a predetermined time after the rotational speed matches the target rotational speed deviation. Thus, the actuator 92 is controlled. [Selection] Figure 1 |
