Abstract: This paper presents a concept of a warning system to prevent rollover of heavy vehicles. The system consists of several sensors which measure the heavy vehicle dynamics. Initially, these dynamics states are observed using observers, and then, knowing the infrastructure characteristics, the risk of rollover is predicted and assessed using the lateral acceleration of the vehicle, the height of the centre of gravity, and the Load Transfer Ratio (LTR). This coefficient is calculated using the estimated load on each wheel.

Keywords: rollover; warning systems; heavy vehicles; sliding mode observers; load estimation; risk prediction; vehicle dynamics.
