摘 要：燃油经济性是车辆使用特性中的重要指标之一。本文首先从特性正向开发的角度，利用层次分析法，确定燃油经济性影响因素间的层次关系，建立判断矩阵，对影响车辆燃油经济性的主要因素权重进行分解。然后以某车型为研究对象，通过cruise软件仿真加以验证，结果表明：车辆燃油经济性的主要因素权重分解合理，为燃油经济性开发目标分解提供了理论和实践依据，提升了整车经济性开发的工作效率。

Abstract： Fuel economy is one of the important indexes in the use characteristics for the vehicle. In this paper， firstly the hierarchy relation between influence factors for fuel economy was determined by the analytic hierarchy process from the angle of the positive characteristic development， and the judgment matrix was built， and the main factors weight for the vehicle’s fuel economy was decomposed. And the simulation software cruise was used to verify the influence factors weight for certain kind of vehicle. The results showed that the main factors weight decomposition for vehicle’s fuel economy was reasonable， which provided the theoretical
