Human-in-the-loop optimization of vehicle dynamics control with rollover prevention

Two Vehicle Dynamics Control (VDC) systems with rollover prevention function are proposed in this paper. Control gains and threshold values of both designs are optimized via the UMTRI preview driver model and Man-Off-The-Street course. The first design consists of yaw rate following and sideslip angle following for path tracking, and is optimized with the information of the lateral load transfer ratio (LTR) to improve its capability of rollover prevention. The second design is similar to the first one, but with additional rollover prevention control. Yaw rate and lateral acceleration are used to design the rollover prevention control. Open-loop and closed-loop maneuvers are used to evaluate the performance of both designs in Matlab/Simulink with a CarSim model.
