Abstract

In this paper a combined control structure with an active antiroll bar control and an active braking control is developed to decrease the rollover risk of heavy vehicles. This control structure also results in a fault-tolerant system since in case of a failure an adequate tuning of the control mechanism guarantees the roll stability. The control design is based on LPV model of the vehicle in which the forward velocity and the lateral load transfer at the rear are selected as scheduling parameters. In the actual controlled system, the compensator also uses the output of a fault detection filter. The operation of the control mechanism is demonstrated in a double lane change maneuver.
