Rollover warning algorithm based-on velocity for buses

This paper presents a rollover warning algorithm based-on velocity for buses, which can assist bus driver to resist rollover around the curve, especially around off-ramp. The paper mainly focused on a dynamic roll stability analysis and a warning method based-on velocity. At first dynamic roll stability limit (RSL) was designed for analyzing dynamic roll stability. And then a warning velocity for alerting drivers to slow down is determined using the measurement of lateral acceleration and the vehicle turning radius. The proposed rollover warning algorithm is evaluated by TruckSim software and simulation results show that the proposed warning velocity can give appropriate prediction of vehicle rollover in the typical scenario.
