Abstract: Vehicle life cycle evaluation is an important tool to explore whether the vehicle has good energy saving and emission reduction benefits and economic benefits. This paper systematically introduces the definition and methodological framework of life cycle costing (LCC) research, life cycle assessment (LCA) and hybrid life cycle assessment (HLCA). Then the research status of vehicle life cycle evaluation is reviewed from four aspects: evaluation scope, evaluation method, evaluation index and identification of important influencing factors. Finally, the future development direction of automotive life cycle research is proposed from the aspects of developing multi-objective optimization, strengthening model dynamics and applying multi-dimensional evaluation results. The results of this study provide a reference for more comprehensive and accurate comprehensive assessment of vehicle cost and its environmental impact in the future.

Key words: life cycle assessment; life cycle costing; hybrid life cycle assessment; energy saving and emission reduction

摘要： 汽车生命周期评价是探究汽车是否具有良好的节能减排效益和经济效益的重要工具。 文章系统地介绍了生命周期成本（LCC）研究、全生命周期评价（LCA）以及混合生命周期 研究（HLCA）的定义和方法框架。然后从评价范围、评价方法、评价指标和重要影响因素识 别四个方面梳理了汽车生命周期评价的研究现状。最后，从发展多目标优化、加强模型动态 化和评价结果应用多维化等方面提出了汽车生命周期研究未来的发展方向。该研究结果为未 来更全面和精准地综合评估汽车成本及其环境影响提供了参考。
