ABSTRACT:
When the vehicle is traveling on an uphill road (step100: YES), the ECU executes a program in which, if the speed of the vehicle is equal to or higher than Vblt (step102: NO) and a speed ratio γ(1) required to secure a sufficient climbing capacity of the vehicle is equal to or lower than a speed ratio γ(2) required to secure a sufficient returnability of the belt of the continuously variable transmission (step106: NO), a belt returnability securing control is executed (step110), and otherwise (step102: YES or step106: YES), a climbing control is executed (step104or step108).
