SRS气囊系统检测与诊断
摘要
近几年来,随着安全气囊制造成本的降低,安全气囊现在已经得到普及使用。当汽车发生正面严重碰撞事故时,安全气囊系统协同三点式安全带对前排成员的头部及胸部提供有效保护。发生侧面碰撞时,侧面安全气囊可减轻成员处于碰撞区域身体部位的伤害程度。本文介绍了安全气囊的国内和国外的发展应用状况,结构组成、工作原理和保护作用的机理等知识,还具体介绍了日本马自达626系列以及本田雅阁轿车SRS系统的特点、组成、原理。分别重点地论述了检测诊断部分,结合所学知识和搜集整理的大量资料,并与具体车型对应建立了大量的还有分别的故障诊断图,写了两款车型具体的故障诊断并且根据诊断过程根据自己的理解附加了诊断流程图也属于本篇论文创新的一部分,最后还通过故障实例来分析故障诊断的具体应用。

Inspection and diagnosis about SRS system
Abstract
In recent years, as the reduction of production costs of the SRS airbags, they have now been widely used. When facing a serious vehicle collision accident, SRS System synergy of three-point seat belts provides effective protection for front members in the head and chest. When side collision occurs, side SRS reduce the extent of the injury at the regional parts of passengers. This paper presents a safety airbag domestic and foreign development application, composition, working principle and mechanism of the protective effect, also briefly introduce characteristics, composition and mechanisms of Japanese Mazda 626 and Honda Accord series SRS system, It focused on detection and diagnosis respectively. With the knowledge we learned, a lot of collected information, and the corresponding fault diagnosis map made for specific models respectively, two specific types of fault diagnosis, According to the diagnostic process and, based on its own understanding of the additional diagnostic flow charts, which also belongs to this paper innovations. Finally, it analyzes fault diagnosis of the specific application through fault case.
