Abstract

The air suspension has the characteristics of nonlinear variable spring rate. To improve vehicle handling stability and ride comfort, the characteristic curve can be designed to comply with the vehicle vibration. In this paper, air suspension and whole vehicle were selected as research object, vehicle’s mathematical model was established based on vehicle dynamic theory, the state space expression and suspension system frequency response function of mathematical model were derived. Fuzzy control was adopted as air suspension control strategy, vehicle’s ride comfort was analyzed and simulated using MATLAB/Simulink. The body vertical acceleration, the body pitch angular acceleration and the suspension deflections are obtained. Simulation results show that the mathematical model is reasonable. The fuzzy controller has a good performance to meet the actual demand. Vehicle’s ride comfort is improved.
