| 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.
