摘　　要：鉴于汽车舱内热环境与室内热环境的相似之处,选取温度、相对湿度、风速、平均辐射温度4个主要客观环境影响因素作为评价汽车舱内热环境的评价指标,分析其对人体舒适性的影响.根据我国相关标准和ASHRAE的热感觉7级分级法将汽车舱热环境分为7个等级,引入模糊(Fuzzy)数学思想和方法到层次分析法(AHP)中建立模糊互补判断矩阵确定各指标的权重集,采用常见三角形隶属函数确定隶属度矩阵,通过权重集和隶属度矩阵建立了汽车舱内热舒适环境的综合评价模型.通过3个实例验证表明,该模型能较好地反映汽车舱内热环境等级,为汽车舱内热环境评价提供了一种简单方法.In view of the similarities between thermal environment in an automobile cabin and indoor thermal environment, a thermal analysis of human comfort in an automobile cabin was made in this article using four major impact factors （temperature, relative humidity, air velocity, and mean radiant temperature） as evaluation indexes. By relevant Chinese standards and ASHRAE 7-point scales for thermal sensation, the thermal environment in the automobile cabin was divided into seven grades. Fuzzy mathematics theory and method was introduced into analytical hierarchy process（AHP） to establish the fuzzy complementary judgment matrix in determining the weight of each index set, and common triangle membership function applied to determine the membership degree matrix. The fuzzy comprehensive evaluation model for thermal comfort in automobile cabins was then built by index set weight and the fuzzy complementary judgment matrix. Three tests were made to verify that the model better reflects the grades of thermal environment in automobile cabins, and proves a simple method in evaluating thermal comfort in automobile cabins.
