Simulation of the sequence of dynamic events causing a vehicle to rollover could provide insight on the vehicle propensity to roll. It can also help in adapting control approaches to avoid vehicle rollover. Two analytical formulations of a similar vehicle modelling approach that reproduces the roll motion of a vehicle, including suspensions and tires, are derived. The effect of tire lift off during heavy cornering manoeuvres is considered. Disturbances such as lateral acceleration and road inputs causing vehicle roll can be applied. Critical vehicle dynamic conditions are simulated using the commercial human vehicle environment (HVE) three-dimensional simulation software and applied as inputs to the derived vehicle roll models. The vehicle dynamic behaviour simulated was validated by comparing with results from HVE. These models can serve as useful tools for testing vehicle roll stability algorithms for active suspension systems and for developing new anti-roll control strategies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
