[email protected] Abstract Roll instability of sport utility vehicles is threatening to the vehicle and traffic safety. A new ap- proach to roll stability control of Sport Utility Vehicles is proposed in this paper. The idea of active camber control to improve roll dynamics is introduced. The study of dynamics of sport utility vehicle is performed using CarSim software package. A rule-based control strategy has been developed which effectively controls camber angle on front axle. Co-simulation is carried out by integrating Matlab/Simulink software with the vehicle simulation environment. It has been shown that active camber can improve roll stability of SUVs and reduce the risk of hazardous traffic accidents. Keywords: rollover; active camber; SUV 1. Introduction The automotive industry has been experiencing a greedy competence in the variety of products as well as an ever-increasing demand for safety standards. Sport Utility Vehicles have in the recent decade attracted noticeable attention. Among the frequently-occurring accidents, roll-over contrib- utes to a vast majority in SUVs due to their high center of gravity and ground height clearance. Sta- tistics reveal a significant fatality of 59% in roll-over accidents of this category of vehicles[1].
