汽车ABS技术的发展趋势研究 在汽车防抱死制动系统出现之前，汽车所用的都是开环制动系统。其特点是制动器制动力矩的大小仅与驾驶员的操纵力、制动力的分配调节以及制动器的尺寸和型式有关。由于没有车轮运动状态的反馈信号，无法测知制动过程中车轮的速度和抱死情况，汽车就不可能据此调节轮缸或气室制动压力的大小。因此在紧急制动时，不可避免地出现车轮在地面上抱死拖滑的现象。当车轮抱死时，地面的侧向附着性能很差，所能提供的侧向附着力很小，汽车在受到任何微小外力的作用下就会出现方向失稳问题，极易发生交通事故。在潮湿路面或冰雪路面上制动时，这种方向失稳的现象会更加严重。汽车防抱死制动系统（Anti-lock Braking System简称ABS）的出现从根本上解决了汽车在制动过程中的车轮抱死问题。它的基本功能就是通过传感器感知车轮每一瞬时的运动状态，并根据其运动状态相应地调节制动器制动力矩的大小以避免出现车轮的抱死现象，因而是一个闭环制动系统。 它是电子控制技术在汽车上最有成就的应用项目之一，汽车制动防抱死系统可使汽车在制动时维持方向稳定性和缩短制动距离，有效提高行车的安全性。 一、ABS的工作原理 汽车制动时由于车轮速度与汽车速度之间存在着差异，因而会导致车轮与路面之间产生滑移，当车轮以纯滚动方式与路面接触时，其滑移率为零；当车轮抱死时其滑移率为100％。当滑移率在8％～35％之间时，能传递最大的制动力。制动防抱死的基本原理就是依据上述的研究成果，通过控制调节制动力，使制动过程中车轮滑移率控制在合适的范围内，以取得最佳的制动效果。ABS系统硬件构成主要由传感器（包括轮速传感器、减速度传感器和车速传感器）、电子控制装置、制动压力调节器三大部分组成，形成一个以滑移率为目标的自动控制系统。传感器测量车轮转速并将这一数据传送至电子控制装置上，控制装置是一个微处理器，它根据车轮转速传感器信号来计算车速。在制动过程中，车轮转速可与控制装置中预先编制的理想减速度的特性曲线相比较。如果控制装置判断出车轮减速度太快和车轮即将抱死时，它就发出信号给液压调节器，液压调节器可根据来自控制装置的信号对制动器的卡钳或轮泵的油压进行控制（作用、保持、释放、重新作用）。这一动作，每秒钟能出现10次以上。 二、ABS技术的发展及应用现状 基于制动防抱理论的制动系统首先是应用于火车和飞机上。1936年，德国博世公司（BOSCH）申请一项电液控制的ABS装置专利，促进了ABS技术在汽车上的应用。汽车上开始使用ABS始于1950年代中期福特汽车公司，1954年福特汽车公司在林肯车上装用法国航空公司的ABS装置，这种ABS装置控制部分采用机械式，结构复杂，功能相对单一，只有在特定车辆和工况下防抱死才有效，因此制动效果并不理想。机械结构复杂使ABS装置的可靠性差、控制精度低、价格偏高。ABS技术在汽车上的推广应用举步艰难。直到70年代后期，由于电子技术迅猛发展，为ABS技术在汽车上应用提供了可靠的技术支持。ABS控制部分采用了电子控制，其反应速度、控制精度和可靠性都显著提高，制动效果也明显改善，同时其体积逐步变小，质量逐步减轻，控制与诊断功能不断增强，价格也逐渐降低。这段时期许多家公司都相继研制了形式多样的ABS装置。 进入90年代后，ABS技术不断发展成熟，控制精度、控制功能不断完善。现在发达国家已广泛采用ABS技术，ABS装置已成为汽车的必要装备。北美和西欧的各类客车和轻型货车ABS的装备率已达90％以上，轿车ABS的装备率在60％左右，运送危险品的货车ABS的装备率为100％。ABS装置制造商主要有：德国博世公司（BOSCH），欧、美、日、韩国车采用最多；美国德科公司（DELCO），美国通用及韩国大宇汽车采用；美国本迪克斯公司（BENDIX），美国克莱斯勒汽车采用；还有德国戴维斯公司（TEVES）、德国瓦布科（WABCO）、美国凯尔西海斯公（KELSEYHAYES）等，这些公司的ABS产品都在广泛地应用，而且还在不断发展、更新和换代。 近年来，ABS技术在我国也正在推广和应用，1999年我国制定的国家强制性标准GB12676-1999《汽车制动系统结构、性能和试验方法》中已把装用ABS作为强制性法规。此后一汽大众、二汽富康、上海大众、重庆长安、上海通用等均开始采用ABS技术，但这些ABS装置我国均没有自主的知识产权。 国内研究ABS主要有东风汽车公司、交通部重庆公路研究所、济南捷特汽车电子研究所、清华大学、西安交通大学、吉林大学、华南理工大学、合肥工业大学等单位，虽然起步较晚，也取得了一些成果。在气压ABS方面，国内企业包括东风电子科技股份有限公司、重庆聚能、广东科密等都已形成了一定的生产规模。液压ABS由于技术难度大，国外技术封锁严密，国内企业暂时不能独立生产，但在液压ABS方面也在做自主研发，力图突破国外跨国公司的技术壁垒，已经取得了一些新的进展和突破。如清华大学和浙江亚太等承担的汽车液压防抱死制动系统（ABS）“九五”国家科技攻关课题，在ABS控制理论与方法、电子控制单元、液压控制单元、开发装置和匹配方法等关键技术方面均取得了重大成果。采用的耗散功率理论，避免了传统的逻辑门限值研究方法的局限性，取得了理论上的突破，研发ABS成功且进入产业化、批量生产阶段。其试样在南京IVECO轻型客车上匹配使用全面达到了国家标准GB12676-1999和欧洲法规EECR13的要求。这对振兴我国汽车工业与汽车零部件业具有划时代意义，标志着我国汽车液压ABS国产化已迈出坚实的一步。同时合肥工业大学也研制出国内具有自主知识产权的液压制动电子防抱系统，率先在HF6700轻型汽车上匹配使用获得成功。国内液压ABS技术含量与国外虽有一定的差距，但在政府的大力支持和国内丰富的人力资源配合下，相信国内可以在较短的时间内在ABS技术某些领域赶超国际水平
