Research on intelligent suspension control strategy integrating driver intent and simulation

This paper focuses on the study of semi-active suspension control strategies for intelligent vehicles, aiming to balance the smoothness and handling performance of the vehicle and enhance suspension performance. A hybrid control strategy that integrates the driver's control intent is proposed. By establishing a dynamic model and using dynamic simulation software along with MATLAB/Simulink to build a combined vehicle simulation model and control model, the simulation results indicate that under different speeds and during lane-changing maneuvers, the semi-active suspension's roll angle suppression is improved by approximately 8% compared to the original passive suspension. Additionally, the vertical vibration on a flat road surface is reduced by about 8%. The proposed control strategy effectively balances the vehicle's driving smoothness and handling performance.
