| 摘 要： | 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。并用该法对某样车进行了优化，经济性得到了一定的提高。

| Abstract: | City bus has characters such as frequently starting-stopping,shifting operation and great fuel consumption. Fuel-economy mainly depends on suitable matching of the transmission parameter. 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. Then an instance has been done to validate i... |
