Abstract An anti-rollover control algorithm based on the Time-To-Rollover (TTR) metric is proposed in this paper. A simple model with steering and direct yaw moment control inputs was constructed to calculate the TTR in real-time. The TruckSim dynamic simulation software was used to verify the control performance, as well as to simulate the system dynamics in the UM-Oakland driving simulator. Both the simple and complex (TruckSim) models were tuned to match the behavior of a 1997 Jeep Cherokee vehicle with lateral acceleration up to 0.6 g. The performance of the proposed control system was compared with other threshold-based rollover-prevention control algorithms. Finally, a human-in-the-loop experiment was conducted to study the performance of the proposed algorithm under more realistic driving conditions.
