Abstract—Rollover propensity is an important safety issue which should be considered early in the design of a vehicle. Although there is a trend toward higher-tech solutions to mitigate rollover risk, we propose that a vehicle designer should also be fully aware of the impact many of the vehicle's design parameters have on rollover propensity. Such awareness is essential to making appropriate engineering trade-offs throughout the vehicle development process. This Study investigates the effect of various vehicle parameters on rollover propensity by performing simulations. The accuracy of the simulation was verified by comparing with experimental data from On-field testing of rollover of sport utility vehicles. The vehicle model used in the simulation study considers the non-linear, transient dynamics of both yaw and roll motion. The vehicle model was subjected to the specific steering input defined by the National Highway Traffic Safety Administration (NHTSA), the Slalom Test. Investigations were aimed at identification of correlations between the vehicle steering parametersand rollover propensity using validated vehicle simulation. During the study it was observed that one of the steering performance parameter aids in reducing rollover propensity. All such results are presented in this paper
