Hardware Design And Analyse Of Anti-lock Braking System Based On XC164CS

There will be many non-stable factors appearing when vehicle brakes urgently, for example skidding, off tracking and steering ability losing. Traffic accident is induced by these factors. Non-stable factors are generated by the locked wheels. These non-stable factors can be avoided by Anti-lock Braking System (ABS) during braking, braking distance can be shorten also, and the safety braking can be guaranteed.In this paper, the present state of ABS in the world is introduced, its basic structure and characteristics are represented too. And the operating principle of ABS controller is discussed detailedly. According to the operating principle of ABS, the single wheel simulation model of ABS which make use of PID algorithm is established for the four-channel four-sensor structure. The model is simulated in MATLAB/SIMULATION environment. The exactitude and feasibility of this scheme is proved by the simulating result. The result has high reference merit to the design of hardware and software. The hardware which uses Infineon XC164CS as its controller core is designed, and the peripheral ciruit is designed also. The smart power switch BTS6510 and MC33385 are utilized flexibly in the design of drive circuit. These switches make the circuit simple, economic, reliable. The drive circuit is designed according to the characteristics of ABS performer. The whole hardware system has the wide range and high precision acquisition ability, it also has the reliable real-time adjusting ability to the hydraulic pressure. The test programme is written for the hardware. And a testing platform is supplied for ABS hardware. The portability and flexibility is increased by the modular programming of this test software. The final software of ABS can be written based on this test programme.
