摘　　要：在考虑了汽车生命周期成本、排放、行程和载重的情况下,提出了一种新的汽车全生命周期评价指标—汽车生命周期行程载重成本。给出了该指标的定义,并以小客车为案例,给出了该指标的计算方法。通过分析给出了提出这一新指标的意义,并指出提高汽车的生命周期行程,提高额定载重,降低成本,减少排放都会有利于降低汽车的生命周期行程载重成本,从而提高汽车的整体表现。该新指标的建立有利于今后更客观全面地评价汽车产品的综合表现,适用可持续发展的需要。Considering the life cycle cost,emission,journal,and load of the automobile,a new indicator,automobile life cycle cost of journal weight,has been proposed. The definition of the indicator has been given and the passenger car was taken as an analysis example. The method and the significance of the indi- cator were analyzed under the case stud）： For improving the total performance of the automobile ,the life cycle journal and average load of an automobile should be increased and the life cycle cost and emission should be reduced. This new indicator is important for us to analyze the total performance of an automobile more objectively and comprehensively. Its application will benefit to the sustainable development.
