ABSTRACT:
Method and apparatus for controlling a continuously variable transmission operatively connecting an engine and drive wheels of a vehicle, wherein a speed ratio of the transmission is controlled such that an actual engine speed coincides with a target engine speed determined based on a currently required engine output and according to a predetermined relation between the target engine speed and the required engine output. The method and apparatus comprise a step or device for restraining a rate of variation in the speed ratio during a time span between the moment when the actual engine speed or output has exceeded a variation-restraint trigger speed or output of the engine, and the moment when the actual engine speed or output has reached the target speed or output. The trigger engine speed or output is determined based on a predetermined transmission efficiency of the transmission, and on the target engine speed or output, and is lower or smaller than the target engine speed or output.
