Simulation and Analysis of Electronic Parking Brake System Based on SimulationX
Electronic parking brake system(EPB)is the development direction of vehicle parking brake system,which belongs to one kind of wire control.SimulationX is used to simulate and analyze the automobile electronic parking brake system.According to the structure and working principle of the mechanical part of EPB system,the simulation models of deceleration mechanism,transmission mechanism and piston ejection mechanism are built,and the co-simulation of SimulationX and Matlab/Simulink is explored.The con-trol model is built in Matlab/Simulink,and the simulation model of EPB system is developed by combining the advantages of these two softwares.The clamping and releasing process of EPB system was simulated and analyzed,and the clamping force results were com-pared with the simulation model built with pure mathematical theory.The results show that the physical model built by SimulationX is real and reliable,and meets the design requirements of EPB system.Compared with the pure mathematical theoretical model,the physical modeling based on SimulationX is simpler,helps to improve the efficiency of modeling and simulation,and provides an im-portant technical support for the development of line control dynamic system products,especially the construction of virtual platform.
