Abstract

Vehicles rollover is considered as one of the most significant causes of injuries and fatalities in road accidents. Thus, automotive engineers have always been interested in devising mechanisms or modifying the vehicle design in order to prevent rollover. In this research, an active stabilizer is used to improve the roll stability of a SUV (sport utility vehicle). A novel fuzzy mamdani controller is designed in order to improve the performance of the anti-rollover system. Performance of the system is then evaluated using CarSim which is a car dynamic simulation software, while the Controller is implemented in Simulink Environment. Matlab/CarSim Co-simulation of the models during standard maneuvers demonstrates the versatility and reliability of the proposed mechanism in improving the vehicle roll motion stability and thus preventing rollover when necessary.
