摘　　要：整车“三高”(高寒、高温、高海拔)环境适应性试验,在整车试验开发和验证过程中至关重要,是必不可少的测试环节。文章选取某款纯电动乘用车,参照中国汽车工程学会标准T/CSAE 163—2020,以主观评价的方式对其在“三高”环境下的整车性能进行综合分析,并总结产品性能优势和缺陷。由评价结果分析可知,该款车型在“三高”环境下整车性能较为均衡,但也存在一些关键问题,如高寒环境下电耗过高、通过冰雪坑洼路况时悬架减震效果差等;高温环境下座椅透气性差、车机突发锁屏、胎压报警无数值显示等;高海拔环境下山路过弯时侧倾感较明显等。The“high-cold,high-hot and high-altitude”environmental adaptability test of the whole vehicle is very important in the process of vehicle test development and verification,and it is an indispensable test link.In this paper,a pure electric passenger car is selected.Referring to the standard T/CSAE 163—2020,its performance under the“high-cold,high-hot and high-altitude”environment is comprehensively analyzed by subjective evaluation,and the advantages and disadvantages of product performance are summarized.From the analysis of the evaluation results,it can be seen that the performance of this vehicle is relatively balanced under the"high-cold,high-hot and high-altitude"environment,but there are still some key problems,such as sudden locking of the vehicle screen,no numerical display of the tire pressure alarm,high power consumption in the high-cold environment.
