Abstract: This paper presents a control scheme to avoid or minimize the risk of vehicle rollover in certain maneuvers. An active suspension control approach using a linear quadratic regulator with output weighting (LQRY) control design is proposed to control the vehicle. This control scheme is integrated with the full vehicle dynamics simulation program. Motions of the sprung mass have been analyzed. The performance of the active suspension control is demonstrated in simulations. Moreover, the comprehensive vehicle subsystems have been modeled to include active suspensions. The dynamic behavior of a vehicle with active suspension was compared to that of a vehicle without active suspension and it was found that, due to roll angle reduction, the active suspension model was found superior for the purpose of the rollover prevention.
