Optimization Of Performance For Automotive Power Transmission System

In the paper, by practical dynamic process instead of steady assumption, mathematical model in a meticulous way and the overall optimization for the design variables, it is applicable to determine the optimum performances for power transmission system. At the same time, according to typical driving cycle for the vehicle fuel economy is taken as objective function and the dynamic performance as restraint so that the rational coordination of fuel economy and dynamic one can be achieved. Finally, the optimum result shows that it is in a closs agreerment with the test result.
