ABSTRACT:
Method and apparatus for controlling a continuously variable transmission for a vehicle for transmitting an output of an engine of the vehicle to its drive wheels, comprising a step or device for detecting a running speed of the vehicle, a step or device for sensing a flow of an intake gas through an intake manifold toward the engine, a step or device for determining a target engine speed based on the detected running speed and the sensed intake gas flow, and according to a predetermined relation among the target engine speed, the running speed and the intake gas flow, which relation is predetermined to attain a required output of the engine with a minimum specific fuel consumption, and further comprising a step or device for controlling the speed ratio such that a speed of the engine coincides with the determined target engine speed.
