Experiment Research on Control Algorithm of ESP System

In this paper a sliding mode controller was designed to calculate the target yaw moment for model tracking control and a fuzzy controller was used to real-timely determine the activation of the algorithm, which ensures the robustness of the control system, while avoiding chattering and undesired intervention of ESP at the same time. After testing the control algorithm on the HIL test bench in double-lane change condition, a comparison was made between the trajectories and handling stability of vehicles with the control algorithm and those without. The simulation and experimental results demonstrate that the designed control algorithm can effectively improve the stability of the vehicle.
