The present invention can attain engine start when switching an electric traveling (EV) mode to a hybrid (HEV) mode under a low shock without giving the feeling of torque omission. Control is started in a mode 2301b in an EV to HEV mode switching request time t1 accompanied with accelerator increase, and a first clutch transmission torque capacity tTc1 for HEV is increased for controlling a driving force, and the cranking of an engine is started according to the dragging of the first clutch before the second clutch for EV and HEV starts to slip. In the mode 2301b, a second clutch transmission torque capacity tTc2 is maintained as an EV mode time maximum driving force evTmax. The mode is shifted to a mode 2303 in a time t2 when the second clutch starts to slide, and the Tc2 is determined so that the start of the engine can be performed according to the dragging of the first clutch while the second clutch is made to slide, and the tTc1 is determined so that the rising of the driving force and the stable slip of the second clutch can be maintained. |
