This paper designs an integrated control strategy of vehicle yaw and rollover stability to enhance the active safety of highway vehicles in turning scenario. A rollover predictor is built based on Time-To-Rollover index. Modified Linear Quadratic Regulation is used in roll stability control, and Partial-Integral design is used in yaw stability control. With Carsim and MATLAB, simulations of fishhook maneuver and double lane-change test are conducted to evaluate the effectiveness of the control configuration and to validate the control method. The result shows that this controller performs well in maintaining vehicle roll and yaw stability. This study provides a theoretical basis towards a unified chassis control of coupled roll and yaw stability.
Keywords:vehicle dynamics; yaw stability control; roll stability control; simulation; Carsim
