Abstract: As consumers pay more and more attention to the fuel economy of automobiles, the main engine manufacturers pay more and more attention to the mass control of the whole vehicle. Research shows that the fuel consumption can be reduced by 7% ~ 8% for every 10% reduction in the mass of vehicle. If the mass of the whole vehicle is to be controlled within a reasonable range, it must be controlled in the new product development stage. At present, the vehicle mass control mainly includes the steps of mass analysis of benchmark competitive products, goal setting, goal decomposition, formulation, promotion of mass reduction scheme, and evaluation of goal achievement. This paper mainly describes the vehicle mass management process, how to set and decompose the mass target, the formulation and promotion of the mass reduction scheme of each system, and the evaluation of the vehicle mass target. Through the above methods, the vehicle mass can be effectively controlled in the product development stage.
