【摘要】 ABS系统作为一种辅助的制动系统在汽车紧急制动时可防止车轮抱死，保证车辆在制动时的侧向稳定性和转向操纵性，同时还可在大多数路面条件下获得最短的制动距离。目前，ABS的应用越来越广泛，许多生产厂家也正在开发新一代的ABS产品。在ABS产品开发过程中，对新产品的试验是一个重要阶段。ABS的试验费时、费力又需要大量的经费，同时ABS的试验需要专门的试验场地，因此又受到试验条件的制约。本文在应用计算机技术的基础上，以装备ABS的车辆的制动性能为研究对象，对ABS系统进行了模拟仿真。实现了ABS系统车辆的计算模拟试验。 本文重点针对中型汽车建立了汽车整车运动模型、制动系统模型、车轮轮胎模型以及ABS的逻辑控制模型。在此基础上，在Windows平台上利用Visual Basic6.0程序设计语言开发了双参数ABS动态模拟仿真系统。通过模拟结果与实车的试验结果的对比分析，证明了利用该系统可部分的取代ABS产品开发过程中的试验，具有一定的实际应用价值。更多还原

【Abstract】 The anti-lock brake system (ABS) as an auxiliary brake system can avoid the tire locking and ensure the lateral stability and turning steering at the time of braking when the vehicle urgent braking. Besides 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 developing the new product test is the most important phase. The test of the ABS is laborious and expensive and needs more time and the special field. So it is limited by the test’s condition. This thesis take the vehicle equipped ABS as research object and simulates the ABS based on the computer technique. It realizes the stimulant test of the vehicle equipped the ABS.The thesis builds moving model of the vehicle, brake system model, the tire model and the logic control model of ABS aimed at the medium-sized vehicle. Based above it uses the Visual Basic6.0 on the Windows plat develop the double parameters ABS dynamic simulation and emulator. By contrasting the stimulant result to the test result it is testified to substitute the test phase partly during the product development and to be of valuable and practical.更多还原
