摘　　要：电机驱动系统的可靠性是衡量电动汽车性能的重要指标。构建了纯电动轿车用异步电机驱动系统的可靠性分析模型,在综合衡量电机驱动系统使用条件的基础上引入可靠性指标评价体系,将主观评价权值同熵权客观权值相结合确定各指标的权重,并采用模糊理论对其可靠性水平作出有效评价。The reliability of motor drive system is an important indicator to measure the performance of EV. On the basis of considering all kinds of using conditions, reliability analysis model and indicator evaluation system was introduced. Indexes weight was determined scientifically by using comprehensive evaluation obtained from combining a subjective evaluation weight with objective entropy weight. An effective evaluation of reliability level was made by fuzzy theory.
