Abstract
A method and an apparatus for controlling the reduction ratio of a continuously variable transmission are disclosed wherein normally the reduction ratio is controlled in response to a desired optimum reduction ratio indicative signal obtained by retrieving the data stored in a memory versus engine load and vehicle speed, but when more vehicle acceleration is needed, the reduction ratio is controlled by a corrected desired optimum reduction ratio indicative signal to increase the reduction ratio.
