Abstract: A new Traction Control System (TCS) based on the integrated control of gear shifting and throttle for the vehicle with automatic transmission is proposed. By means of differential geometry theory, the slip control system with non-linearity and uncertainties is transformed into a linear one. Then, the sliding mode control is introduced for the purpose of raising the robustness of the system. Furthermore, according to the dynamic programming, the optimal throttle opening and gear position are solved for the required driving torque. The simulation results indicate that the present TCS is characterised by its simple structure and good performance.
