ABSTRACT:
A method of controlling speed reduction ratio comprises the following steps: determining "EB-REF-engine speed" which is higher than "R-REF-engine speed" when the accelerator opening is substantially closed and the vehicle brake is applied simultaneously, and controlling speed reduction ratio so that the actual engine speed coincides with the EB-REF engine speed. Although the above method also comprises the following steps as a normal ratio control: setting the R-REF engine speed in relation to the accelerator opening, and controlling speed reduction ratio so that the actual engine speed coincides with the R-REF engine speed.
