Abstract
A continuously variable transmission (CVT) is controlled such that an actual engine speed becomes equal to a desired engine speed. The desired engine speed is set to a value not less than a minimum engine speed for fuel cut so that fuel is to be cut when an intake throttle valve is at a position below a predetermined position during the deceleration of a vehicle. When the position of the throttle valve exceeds the predetermined one, the desired engine speed is set during a predetermined period to a value different from a usual value which is defined as a function of parameters of the vehicle.
