The Combined Control of the Steering and Braking System of the Vehicle Rollover Avoidance Control

This paper analyzed vehicle rollover dynamic model when vehicle steering and rollover is occurring, which based on basic vehicle rollover problems. Three-degree-of-freedom vehicle roll model which considering roll angle was established, and physical quantities of model were analyzed. Input and output quantities were analyzed based on vehicle roll model, feedback quantities were determined, too. Controller state reset was added into traditional controller switch module so as to avoid undesired instantaneous pulse which appeared during switching. Three-degree-of-freedom vehicle roll model was put up in Simulink, Controller parameters set was tuned and I/O data were prepared to optimize control effect. The control method in this paper was verified finally.
