A power transmission comprises a continuously variable transmission CVT, which transmits a rotational driving force from an engine to wheels, a starting clutch 5, which sets variably the transmission capacity of the continuously variable transmission, and a control valve CV, which controls the engagement actuation of the starting clutch 5. While a vehicle equipped with this power transmission is decelerating, the engagement of the starting clutch is controlled to transmit a rotational driving force from the wheels to the engine. Specifically, the engaging capacity of the starting clutch is controlled to bring the difference between the input and output rotational speeds of the starting clutch into a predetermined range, and the control pressure of the starting clutch that brings this difference in the predetermined range is learned, i.e., stored in memory and renewed, as a control value for the next deceleration of the vehicle. _23_ |
