汽车转向系统缺陷风险评估准则与汽车召回案例

摘要

Automobile steering system defects affect the automobile safety, and are important causes of automobile-recal . Risk assessment guidelines were proposed for automobile steering system defects to improve the manage efifciency of automobile recal , based on risk matrix and risk level after analyzed automobile steering system failure forms and their inlfuence. Automobile recal cases caused by steering system defects were analyzed using the risk assessment guidelines. The results show that the defect risk matrix method can identify steering system defects and evaluate the risk level. Therefore, the defect risk assessment guidelines can assess the automobile steering system defects risk and automobile recal , also can be extended to other defects of automobile, and enhance the process of automobile recal .%汽车转向系统缺陷严重影响汽车的行驶安全性，是汽车召回的重要原因之一。为了提高汽车召回的管理效率，该文分析了汽车转向系统故障缺陷的形式及其影响，以风险矩阵法和风险等级为依据，提出了一种汽车转向系统缺陷风险评估准则。以此分析了汽车被召回的案例。结果表明：本文的风险矩阵法，能识别转向系统缺陷，并评估其风险。因此，本汽车转向系统缺陷风险评估准则，能指导汽车转向系统缺陷的风险评估和汽车召回，也可扩展到汽车其他缺陷的风险评估中，服务于汽车召回。
