The Effect Of Anti Roll Bar On The Heavy Vehicle Handling

Vehicle rollover contributes to huge number of tragic accident in recent years. Heavier vehicle have greater tendency to rollover due to their lower roll stiffness and
smaller rollover threshold. While common passenger car could overcome the stability issue by means of speed reduction, having higher points of centre of gravity,
it is impossible for heavier vehicle to seek balance between stability and speed. Simple balance spring device known as anti roll bar has been introduced to passenger
car to enhance the roll stiffness of the suspension system without having to trade off speed and ride comfort. A system with the same goal has been developed for heavier
vehicle. However, the system requires active feedback control system which resulted in the creation of a complex safety control system known as active anti roll system.
