汽车安全技术的发展状分析毕业论文.docx

摘 要随着世界汽车工业的不断发展，汽车保有量迅速增加。在汽车给人们的生活和工作带来方便的同时，随之而来的交通事故严重危害了人们的生命和财产安全，于是人们对交通安全日益重视，而汽车安全技术对减少交通事故起着重要作用，使汽车安全技术的研究成为当今社会关注的重点。虽然对汽车安全技术的研究持续了一个多世纪，使交通事故数量有所减少，但是近年来交通事故的绝对数量却居高不下。因而，研究汽车安全技术的发展现状及趋势具有重要意义。论文简单介绍了汽车主、被动安全技术的发展现状。通过分析C-NCAP碰撞测试结果和典型汽车安全装置对减少交通事故的作用，重点探讨了汽车安全技术与交通安全之间的关系，充分显示了有效的汽车安全技术的重要性。在分析中找出现代汽车安全技术存在的一些不足，并在此基础上，从微观角度分析了主、被动安全技术的发展新方向。最后得出结论：集成化、智能化、系统化是未来汽车安全技术发展的宏观趋势。关键词： 汽车； 电喷汽油发动机； 电喷柴油发动机。AbstractWith the auto industry is increasingly developed, the sharp increase in global car ownership. Chinas vast land, as the most populous country in the world, the demand for car essential convenient transport, utilization great test of learning ability and practical experience in vehicle maintenance and repair personnel holdings.By engine as the core energy of the car to work properly, often working in the idle state, such as a red light, and also the ignition start. Necessary in the case of the principle structure, the depth of its common fault analysis and diagnosis as vehicle maintenance practitioners.The paper briefly introduces the current status of the active and passive safety technologies. The paper analyzes the C-NCAP crash test results and the significance of typical vehicle safety devices to reduce the traffic accidents, which sufficiently shows the importance of the efficient automotive safety technology. The shortages of the current automotive safety technology are found during the analysis. On this basis, the paper separately analyzes tends of the active and passive safety technologies from the microcosmic point of view,and educes the conclusion: integrationism, intelligentize, systematism are the macroscopical tends of it in the future.
