Abstract
According to this invention the driver's will to accelerate and decelerate is detected by a pressing amount of an accelerator pedal, or the like. Speed ratio of a continuously variable speed transmission and air-fuel ratio of air mixture in a combustion chamber of an engine are controlled according to that will. As a result, a WOT (Wide Open Throttle) period in which the vehicle travels with the optimum rate of fuel comsumption becomes longer, and an appropriate responsive property in acceleration and the maximum output horse power of an engine is ensured.
