Fuel consumption of the engine becomes sufficiently economical when it runs under operating conditions of low speed and high torque rather than of high speed and low torque. However, it is difficult for automobiles to run under such economical conditions because acceleration is frequently required. Therefore, if an automobile engine is operated by consolidated control with continuously variable transmission (CVT), the minimum fuel consumption will be achieved, satisfying the driver's demand for a particular vehicle speed. The advantage of this consolidated control for fuel economy depends on several factors, such as specifications of the automobile, the performance of controllers, the driving mode of the automobile and the performance of the control actuators. In this report, the required CVT's operating speed which involves the performance of the actuators was investigated by simulation studies as well as theoretical analysis.
