摘　　要：为进一步研究不同级别智能网联汽车全生命周期节能减排绩效,基于生命周期评价方法(LCA),以某国产合资紧凑型纯电动乘用车为评价对象,搭建智能网联汽车生命周期评价模型,研究分析其全生命周期的矿产资源消耗、化石能源消耗及环境排放影响;进而基于不同级别智能网联汽车采用智能装备的差异,对L0~L5级别智能网联汽车全生命周期各阶段能源消耗和环境影响进行评估预测与对比分析。研究结果表明:在智能网联汽车全生命周期矿产资源消耗方面,原材料获取阶段占比最高;在化石能源消耗方面,运行使用阶段占比最高;在综合环境影响方面,受中国电力结构影响,运行使用阶段环境影响综合值最大;随着智能化程度的不断提高,智能网联汽车相邻级别间全生命周期化石能源消耗可降低3.5%~6.3%,GWP、AP、EP、POCP环境排放最高可分别降低约13.9%、13.3%、13.7%、11.7%,其中使用阶段环境排放降低程度最为明显;综上,通过进一步加强汽车轻量化研究,拓展新型材料在智能网联汽车领域的应用,合理优化我国电力结构布局,提升车辆自主决策水平,加快云平台与大数据等关键技术在智能网联汽车上的应用等途径,可有效提升智能网联汽车节能减排效果。In order to further study the energy-saving and emission reduction performance of different levels of intelligent connected vehicles,this paper based on the life cycle assessment(LCA)method,established an intelligent connected vehicle life cycle evaluation model with a domestic joint venture compact pure electric passenger car as the evaluation object,research analyzed the impact of mineral resource consumption,fossil energy consumption and environmental emissions in its entire life cycle.In addition,based on the differences in the intelligent equipment adopted by different levels of intelligent connected vehicles,the energy consumption and environmental impact of L0-L5 intelligent connected vehicles at each stage of the whole life cycle are evaluated,predicted and compared.The research results show that in terms of the consumption of mineral resources in the life cycle of intelligent connected vehicles,the raw material acquisition stage accounts for the highest proportion,in terms of fossil energy consumption,the operation and use stage accounts for the highest proportion,in terms of comprehensive environmental impact,affected by China’s power structure,the comprehensive value of environmental impact in the operation and use stage is the largest.According to the differences in the life cycle resources and energy consumption and environmental impact of L0-L5 vehicles of different intelligent levels,it is concluded that with the continuous improvement of the degree of intelligence,the fossil energy consumption of the whole life cycle between the adjacent levels of intelligent connected vehicles can be reduced by about 3.5%-6.3%,and the environmental emissions of GWP,AP,EP,AND,POCP can be reduced by about 13.9%,13.3%,13.7%and 11.7%respectively,of which the environmental emissions at the use stage are the most obvious.In summary,by further strengthening the research on automobile lightweight,expanding the application of new materials in the field of intelligent connected vehicles,rationally optimizing the layout o
