Integrated Design for Steering System and Suspension

Article Preview

Abstract:

A design method of integrated control for suspension system and steering system is proposed based on vehicle ride comfort and handling stability. A car simulation model is built applying the software of MATLAB and ADAMS. The construction and characteristic of the integrated simulation model of the suspension system and steering system is illustrated in detail which uses fuzzy method and PID method. Using the simulation model, body vertical acceleration, roll angle and yaw angular velocity are measured in three status which include no control condition, the individually control for active suspension, and the integration control respectively. The simulation data show that the integrated control method synchronously ensures the ride comfort and handling stability.
