Abstract
A continuously variable transmission for use in a motor vehicle. A desired engine speed is defined as a nearby engine speed which produces a minimum specific fuel consumption when the engine generates a horsepower requirement as a function of either accelerator or throttle position. The desired engine speed is calculated in accordance with either the detected accelerator stroke or the detected throttle position and vehicle speed. The continuously variable transmission is feedback controlled such that an actual engine speed equals the calculated desired engine speed.
