A continuously variable transmission (CVT) for a motor vehicle. A desired speed ratio of the CVT is defined as a substantially continuous function of a throttle position and a vehicle speed. The desired speed ratio is calculated in accordance with a detected throttle position and a detected vehicle speed. The CVT is controlled in such a way that an actual speed ratio equals the calculated desired speed ratio.
