Integrated Automotive Chassis Control Simulink Simulation with Suspension and Steering Systems

In this simulation, we utilize Simulink to develop an integrated automotive chassis control system that combines both suspension and steering subsystems. The simulation implements key control algorithms through Simulink blocksets, including PID controllers for suspension damping and steering assistance systems. Through this integrated approach, we can comprehensively analyze the working principles of automotive chassis systems and explore optimization strategies for enhancing suspension comfort and steering responsiveness. Using Simulink's simulation tools, we model various driving scenarios including different road surface conditions (such as bumpy terrain and smooth highways) and cornering maneuvers. The simulation incorporates mathematical models representing vehicle dynamics, with specific focus on quarter-car models for suspension analysis and rack-and-pinion models for steering systems. Key Simulink functions employed include Stateflow for control logic implementation and Vehicle Dynamics Blockset for realistic motion simulation. Through these simulated experiments, we can evaluate system performance metrics such as ride comfort, handling stability, and path tracking accuracy. The simulation results enable us to draw conclusions about system integration effectiveness and provide data-driven recommendations for improving chassis performance and stability through parameter tuning and control strategy enhancements.
