Abstract :
A passenger car equipped with continuously variable transmission (CVT) can steplessly change speed ratio according to road resistance during car driving. In the last decade, cars with CVT have rapidly increased in the world for smooth shifting without any uncomfortable shift shock, superb dynamic performance, low waste emission and good fuel economy. The paper establishes a dynamics model of a power train composed of engine-transmission-road. The integrated control of transmission-engine is investigated for improving a vehicle´s fuel economy, dynamic performance, as well as vehicle speed controllability in terms of driver requirements
