| Abstract: | This paper considers the analysis and design of a differential gear mechanism type electric power assist steering system. This automotive steering system the can vary the overall steering ratio as a function of the vehicle's forward speeds has the potential to enhance the on-center handling performance of the vehicle for different driving situations. Dynamic simulation results demonstrate that differential gear mechanism steering system is capable improving the on-center handling performance of the vehicle. |
