[汽车防抱死制动系统.doc

汽车防抱死制动系统，简称 ABS（Anti－Lock Brake System）系统。是利用电子电路自动控制车轮制动力，并可以充分发挥制动器的效能，提高制动减速度和缩短制动距离，且能有效地提高车辆制动地稳定性，放置车辆侧滑和甩尾，减少车祸。ABS 既有普通制动系统的制动功能，又能防止车轮锁死，使汽车在制动状态下仍能转向，保证汽车的制动方向稳定性，防止产生侧滑和跑偏，是目前汽车上最先进、制动效果最佳的制动装置。本文将详细介绍汽车防抱死制动系统的工作原理和常见故障，以及故障的诊断和解决方法。主要是针对通用汽车系列的 ABS 故障诊断方法进行探讨。 关键词：通用汽车； ABS； 故障； 诊断方法； 探General buick ABS fault diagnosis and maintenance Tutor:Mengjun Hao Professional Car 2009 No.200911921 Name:Daiqiang Wu Abstract Anti-lock braking system, or ABS (Anti-Lock Brake System) System. Is the use of electronic circuits control wheel braking force, and can give full play to brake performance, improve braking by the speed and reduce the braking distance and can effectively improve vehicle braking stability, Placing vehicle skidding and tail flick, reducing traffic accidents; ABS brake system of the existing ordinary braking function, but also to prevent wheel lock so that the car under braking can to ensure that the direction of vehicle braking stability , To prevent skidding and deviation, is currently the most advanced car, braking effect of the best brakes. This paper will detail the Anti-lock brakinystem and the principle of common fault and the fault diagnosis and solution. Is mainly directed against Chinas production of the Toyota assembly line of ABS fault diagnosis method to explore.
