The simulations on dynamic stability of Sports Utility Vehicles using Carsim/Vehsim software are presented on this paper with the aim of studying the rollover process occurring in such vehicles. Carsim/Vehsim is an integrated simulation package that has been developed for chassis dynamics controls and integration. The simulation procedure makes use of dynamic testing maneuvers (Fishhook tests, J-Turn test and Double Lane Change test) recommended by NHTSA to evaluate the antirollover propensities of SUVs on road. The simulation results emphasize the need for better understanding of SUV rollover performance and characteristics that are very essential in enhancing vehicle design. Furthermore, the simulation dramatically shows less development time and cost reduction compared to field testing. This paper, in general, investigates the dynamic rollover characteristics of 4 SUVs in 2 different road conditions.
