摘　　要：介绍了利用汽车制造企业售后服务网络反馈的故障信息对汽车进行可靠性评价的方法。该方法的关键是故障信息子样的确定,传统的方法是以销售信息来确定子样,本文提出了以首保信息为依据确定子样的新方法。对某一国产轿车进行了可靠性分析,得出了整车的故障里程分布规律,计算了相关的可靠性指标,对整车可靠性进行了总体评价。The automotive reliability analysis method based on failure information from after-service webs of automobile manufacture is discussed in this paper. As the key factor of the method, a new access, using the first-maintenance information instead of the traditional sale information to ascertain the sample of failure information, is put forward. According to this method, the reliability of a kind of native car is analyzed, and the law of failure distribution and the reliability evaluating values are obtained. Then, the reliability estimation of this kind of car is given in whole.
