Rover warning algorithm of heavy commercial vehicle based on model prediction

Considering that the heavy-duty commercial vehicle(HCV) is vulnerable to rollover because of its high mass-center and bulky dimension, a HCV rollover warning algorithm was developed based on the rollover time prediction. The algorithm was derived from the built simplified HCV rollover warning model and the determination of dynamic rollover threshold. A real-time rollover warning controller to perceive the rollover risk in dangerous conditions was developed and verified by in-situ vehicle tests. The test results show that the derived warning algorithm worked well in the developed controller, it was capable of reminding the driver to take measures timely to avoid vehicle rollover at its approaching.
