In a vehicle that includes an auxiliary transmission mechanism 6 where a high-speed range and a low-speed range are switchable, a carrier 61 CA of an auxiliary transmission mechanism 6 is coupled to a motor-generator 67 to allow power transmission. When switching from the high-speed range to the low-speed range, the motor-generator 67 increases a rotational speed of the carrier 61CA such that a rotational speed of a low-speed range piece 62L is synchronized with a rotational speed of an input shaft 31. When switching from the low-speed range to the high-speed range, the motor-generator 67 increases a rotational speed of the carrier 61CA such that a rotational speed of an output shaft 32 is synchronized with a rotational speed of the input shaft 31. This allows range switch with a reduced gear change shock even while the vehicle is running.
