Abstract


Automotive anti-lock braking system (ABS), which is an automotive safety advantages of non-slip, anti-lock control system . ABS is the conventional brakes based on the improved technology , can be divided into two kinds of mechanical and electronic . Hyundai Motor installed on a large number of anti-lock braking system , ABS , both ordinary braking system braking function , but also to prevent wheel lockup , still steering the car under braking , to ensure that the direction of the car 's braking stability to prevent skidding and wandering , is currently the most advanced automotive brake braking effect . This paper introduces the development status at home and abroad for automotive anti-lock braking system , discusses the basic structure and its characteristics of anti-lock control system , and a detailed discussion of the antilock controller works . According to the working principle of the anti-lock braking system , the use of PID control algorithm , the establishment of the slip rate based on the single wheel ABS system simulation model and MATLAB / SIMULINK environment its dynamic simulation , the simulation results show that the program correctness and feasibility ; then complete hardware control circuit design , including design features of the implementation of the device for the power of the anti-lock braking system , anti-lock braking system drive part of the circuit , and flexibility in the use of highly integrated intelligent power drive module BTS6510, MC33289, the drive circuit is simple, economic and reliable . Overall hardware system with a wide range of high-precision wheel speed acquisition and processing , as well as timely and reliable hydraulic adjustment ability to meet the design requirements of the anti-lock controller hardware ; final hardware circuit to the NI LabVIEW platform , using a modular written in programming methods , the preparation of the system data acquisition and control algorithm enhances the portability and flexibility of the program , the control software for the ABS system has laid a foundation and the drum brake tester as a test platform for the soft The hardware joint test . The system will auto ABS control algorithm provides a good platform to improve future the ABS system development efficiency and shorten the development cycle of new products .
