In this paper ,the four-circle fuel consumption and constant speed 100km-oil consumption have been weighted summation as the whole goal function,making optimization for its minimum on transmission parameters,its parameters has been figured out by maximum likelihood esti- mation.
城市客车起步停车换挡频繁,燃油消耗量大,而传动系参数的合理匹配与燃油经济性的好坏有密切联系,以四工况燃油消耗量和等速百公里燃油消耗量加权建立目标函数,由最大似然法计算加权系数,对传动系参数进行优化。
