Because it can make the vehicle achieve the minimum brake distance on most of the road. Now the ABS is used more and more widely and many manufacturers are developing the new ABS. During braking instant ,ABS can avoid the tire locking and ensure the lateral stability and turning steering at the time of braking when the vehicle urgent braking. The principle, function and present situation of ABS (Antilock Braking System) are briefly introduced, at last key technology and the developing trend of ABS are discussed. Keywords： automobile39。s Antilock Braking System； braking performance； slid rate；ABS technology； trend of development. 黃岡職業(yè)技術(shù)學(xué)校畢業(yè)論文 III 目錄 摘要 .................................................................................................................................................................................I ABSTRACT.....................................................................................................................................................................
