To reduce the shock at the time of connection (engagement) of a clutch and obtain a smooth vehicle starting feeling even in the case where the throttle opening at the time of vehicle starting is comparatively large. At an actual engine rotational speed corresponding to a half-clutch state of a starting clutch, a target gear ratio control of a continuously variable transmission is performed by determining a target gear ratio from a target engine rotational speed, whereas at an actual engine rotational speed corresponding to an engaged state of the starting clutch, the gear ratio is so controlled that t he actual engine rotational speed will converge to the target engine rotational speed. Therefore, when it is intended to start the vehicle with a comparatively large throttle opening, it is possible, in the half-clutch condition, to obviate a rise in the actual engine rotational speed with the gear ratio position sticking to the LOW position, so that a predetermined driving force can be attained when the starting clutch is engaged.
