Abstract: A dynamic vehicle simulation and control algorithm are developed in this study which utilise a nonlinear tyre model and coordinated four-wheel steering and braking systems to improve vehicle directional stability, controllability and response to driver|s command on different road conditions. The linear programming algorithm is utilised for the evaluation of the distribution of the normal forces on the tyres and the optimum tractive/braking forces required for ensuring stability. The computer simulation of the developed four-wheel steering and braking system shows that the proposed approach can considerably enhance the stability and robustness of the performance of the vehicle especially under slippery road conditions.

Keywords: four-wheel steering; braking forces; nonlinear models; tyre modelling; longitudinal forces; slip angle; yaw rate correction; dynamic modelling; vehicle dynamics; vehicle stability; simulation; slippery roads; slippery surfaces; road surfaces.
