Tractor semi-trailer vehicle often poses serious highway safety risks due to its excessive weight, larger dimensions, directional and roll stability limits. There are many tractor semi-trailer vehicle accidents caused by lateral instabilities, which may be classified into two types: rollover and yaw instability. Rollover of tractor semi-trailer vehicle frequently occurs while directional maneuvers at high speed on roads with high adhesion coefficient. Dynamic rollover indicators are based on the loss of wheels from the ground (wheel lift-off). The rollover indicators of the tractor semi-trailer vehicle are more complicated than single vehicles. In this paper, a full dynamic model of tractor semi-trailer vehicle is developed based on Multibody System Dynamics analysis and Newton-Euler equations. The model includes adaptive sub-models as well as suspension model, non-linear tire model, fifth wheel model, and so on. This model is applied to determine the rollover indicators of the tractor semi-trailer while turning maneuvers.
