Abstract: The structure and principle about combine brake control system of heavy vehicle were introduced, the control characteristic and system characteristic for hydraulic control system were researched. In MATLAB/Simulink circumstance, the nonlinear model about the control component and system was built, the results of simulation were given. The control effect is ideal  comparing simulation results with the experiment data. The analysis shows that nonlinear of valve and the characteristic of hydraulic cylinder are important factor to the hydraulic system dyamic export.
