Slip of clutch engagement when a hybrid vehicle shifts from motor drive to hybrid drive is reduced to reduce shock. A hybrid vehicle 10 includes an internal-combustion engine 12, an engine starter ISG motor 14, a main motor 26 that drives rear wheels, a CVT pulley belt 32 disposed between an engine output shaft and a front wheel shaft, a clutch 16 connected between the output shaft of the internal-combustion engine and an input shaft 31 of the CVT, a battery 24, and a hybrid controller 50. When the hybrid controller determines that there is a need to add a traction force of the engine from a state where the vehicle is driven by the main motor 26 alone, the hybrid controller controls the respective components so as to start the engine 12 by the ISG motor 14 in a state where the clutch 16 is disengaged, control a speed ratio of the CVT so that a CVT input speed achieves a target speed for starting clutch engagement, detect the engine rotation speed, detects the CVT input speed, and engage the clutch 16 when a difference between those speeds falls within a predetermined range.
