Designing An Active Anti Roll Bar Control System For A Semi -Trailer

Résumé

Nowadays, tractor semi-trailer heavy vehicles are the most popular transport vehicle in the world because of their benefits. However, the traffic accidents related to these vehicles usually are serious consequences. The main reason causes these accidents is the loss stability of tractor semi-trailer heavy vehicles, particularly is the roll-over phenomenon of them. In order to improve the roll stability, most modern these vehicles are equipped a passive anti-roll bar system. However, the passive anti-roll bar does not meet the required stability when the vehicle is in emergencies. This paper investigates the influence of the suspension roll damping and roll stiffness parameters on the stability of the tractor semi-trailer and designs an active antiroll bar control system for semitrailer, by using Linear Quadratic Regulator (LQR) method. The obtained results show that these suspension parameters do not meet well for the vehicle roll stability when the tractor semi-trailer is in a cornering maneuver. In addition, the simulation results compare the performance between the passive and the LQR active anti-roll bar systems for semi-trailer show that by using the active system the reduction for the roll angle of the sprung mass is about 43%, 50% for the normalized load transfer and 50% for the roll angle of the unsprung mass.
