The main aim of this paper is to investigate the influence of integration of vehicle dynamics control systems by proposing new control architecture to integrate the braking, steering, suspension and driveline. A 6 DoF nonlinear vehicle handling model is developed for in Matlab/Simulink. The modelling work contains linear suspensions with nonlinear tyres suitable for combined slip conditions. The results are validated against commercially available vehicle dynamics software. All the four active chassis control systems are evaluated over the entire range of vehicle handling region in standalone mode through simulation. Based on the analysis of these four standalone controllers, a novel rule based integration strategy is proposed to improve the vehicle handling. A comparison of the proposed integrated control strategy and the standalone control strategy is carried out and the results of the simulation are found to prove that the integrated control strategy improves vehicle stability across the entire vehicle operating region.
