ABS系统的故障诊断 毕业论文.doc

I ABS 系统的故障诊断毕业设计(论文)中文摘要汽车是现在最主要的交通工具之一,汽车的安全性,经济性和舒适性是人们关注的核心问题。汽车电子的发展,改善了汽车的安全系统,保证汽车在高速行驶和复杂路况道路中行驶的安全。在现代新型汽车中,为了增强驾驶安全性能,普遍安装了制动防抱死系统(简称 ABS) 。ABS 系统的作用是保证汽车在任何路面上进行紧急制动时,能根据车轮的转速,自动调整制动管路内的制动液压力大小,去控制和调节车轮制动力,使汽车的滑移率始终保持在 15%~25% 之间,即车轮边滚动、边滑动状态,以防汽车出现侧滑、跑偏和丧失转向能力,从而防止车辆在紧急制动时可能发生倾翻的交通事故。 ABS 系统在使用中体现了其稳定性和安全性,现在国内外的轿车、客车生产厂都将其为标准装置,运用于汽车上,而国产车也越来越多采用这一新技术。所以, ABS 系统故障的诊断与排除技术也成为我们汽车修理中必须掌握的知识之一。关键词: 汽车制动防抱死系统故障诊断故障排除技术发展 II 毕业设计(论文)外文摘要 Title : Fault diagnosis of ABS system Abstract : Cars are now one ofthe most important part oftransport, car safety, economy fort are the core issues ofconcern. Development of automotive electronics, improved the car security system, guaranteed car athigh speed plicated road conditions and road safety. Inmodern cars, inorder toenhance driving safety performance, generally installed antilock braking system (ABS for short). ABS system ofrole isguarantee car inany pavement for emergency brake Shi, can under wheel ofspeed, automatically adjustment brake pipeline within ofbrake liquid pressure size, tocontrol and regulation wheel system power, makes car ofslip rate always keep in15%~25%, iswheel edge scroll, and edge sliding State, case car appears sideslip, and run partial and lost steering ability, toprevent vehicles inemergency brake Shi may occurs pour turned oftraffic accident. ABS system inuse reflects its stability and security, domestic and foreign cars, now buses production factory for standard devices, used incar, domestic car more and more with this new technology. Therefore, the technology offault diagnosis and troubleshooting ofABS system has also e one ofour auto repair knowledge must beacquired in.
