Study on the Dynamic Characteristics of Pneumatic ABS Solenoid Valve for Commercial Vehicle

As the most key parts of pneumatic Antilock Braking System (ABS) for commercial vehicle, the dynamic characteristics of pneumatic ABS solenoid valve directly influence on the effectiveness of ABS. Modeling and simulation of pneumatic ABS solenoid valve is presented in this paper on the top of MATLAB/ SIMULINK, Hardware in the Loop (HIL) test bed of pneumatic ABS is developed, and the test of dynamic characteristics of pneumatic ABS solenoid valve is completed. Based on the results of simulation and test, the factors which influence the dynamic characteristics of solenoid valve is analyzed, and the design guideline of solenoid valve is brought forward.
