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
