摘要
ABS的控制方法和其算法是汽车安全领域的ABS研究的核心,由于起步时间、知识产权保护、市场竞争及其它方面的原因,我国的汽车工业仅采用国外的ABS的公司提供的集成产品。因此研究ABS控制方法的理论,并开发出基于实用控制算法的ABS的控制系统,是填补国内汽车安全领域的ABS研究短板的关键步骤。它同时亦是高校诸如车辆工程专业研究的主要领域之一。因此,开发一套用于实验和教学的ABS控制系统十分有工程意义,通过它能了解和验证ABS控制方法的可行性和可靠性。
本文深入研究了汽车ABS控制原理和理论,建立了单轮车辆动力学模型;加入了路面识别系统确定实时路面,它能够更准确地调整制动力矩;用模糊控制方法实现了汽车ABS控制;搭建了在环仿真平台,在上位机采用VB. NET开发环境建立应用于单轮车辆动力学模型及其制动器模型,在下位机采用DSP模拟汽车ECU单元以建立ABS模糊控制的算法,并结合二者做闭环半实物仿真及分析;验证了模糊控制器应用于ABS的有效性;初步扩展了控制算法应用的种类。
结果表明,基于路面识别系统的模糊控制系统能够根据不同的路面设定最佳滑移率,从而使ABS控制的制动力矩的输出更加精确,有效地提高了制动性能,提升了车辆的安全性;验证了所设计的在环仿真实验平台能够比较真实、精确地模拟实车的ABS制动过程,对于实验和教学有着实际的意义。
ABS's control method and algorithm is the core of the area of Automobile Safety. Due to starting time, Intellectual Property Protection, market competition and other reasons, automobile industry in our country can only use integrated product provided by foreign ABS companies. Therefore, researching the theories of ABS control method and developing ABS control system based on practical and effective control algorithm are key steps to remove shortcomings of the research on ABS in our country. At the same time, it is also the main research area of universities'relative departments, such as Vehicle Engineering Department. Therefore, developing the ABS control system for experimental and teaching use owns huge practical engineering meaning. The feasibility and the reliablity of the control methods can also testified through it.
This thesis deeply researches on ABS control principle and theory. The quarter vehicle model is established, the pavement identification system which can precisely adjust braking torque to identify real-time pavement is added and the fuzzy control method to realize vehicle ABS control is employed. Then the close-loop Hardware-in-the-loop Simulation experimental platform based on the host computer using VB.NET and the slave ECU(DSP) using fuzzy control algorithm is built and analyzed. The good effectivity of using fuzzy controller to ABS is also testified. The variety of ABS control algorithms'applications is initially extended.
The Results indicate that the fuzzy control system can set the best slip ratio according to different pavement based on the pavement identification system. It makes the output of braking torque more accurate, effectively promotes braking character and advances the security of vehicles. The Hardware-in-the-loop Simulation experimental platform designed is also verified. It can actually and accurately simulate the ABS braking process of real vehicles. It prossesses practical significance for a lab and teaching.
