Abstract
A method of controlling speed reduction ratio in a continuously variable speed transmission comprises the steps of setting a prescribed parameter corresponding an accelerator opening which is opened to a certain extent from a fully closed condition setting a reference engine speed corresponding to a parameter which represents a driver's intention of acceleration so as to increase as said parameter increase from said prescribed parameter when said parameter is in a range higher than said prescribed parameter setting said reference engine speed so as to increase as said parameter decreases from said prescribed parameter when said parameter is in a range lower than said prescribed parameter, and controlling said speed reduction ratio so that the engine speed coincides with said reference engine speed.
