摘要：	A variety of roll stability enhancement technologies exist or are under active development. An enhanced understanding of the events and conditions that lead to rollovers of SUVs in traffic crashes can identify opportunities for these technologies to intervene and reduce the incidence of rollover. Literature on SUV rollover is reviewed. Data from FARS and GES are analyzed to determine factors that affect rollover. SUVs are over three times more likely to roll over, given involvement in a traffic accident, than passenger cars. In single vehicle crashes, 29.9%of SUVs rolled over. Factors associated with higher rollover probability include driver age less than 25, driver drinking, three or more occupants in the vehicle, traversing a curve, road speed limits greater than 50 mph, roadway grades, ice on the roadway, and (for multiple vehicle accidents), travel between midnight and 6 a.m. In addition, 262 SUV rollovers in the NASS CDS file were reviewed and major rollover event sequences were identified. Three primary scenarios were defined: Loss of control, collision with another motor vehicle, and all other roll sequences. In the latter group, three pre-cursor scenarios were defined: drift off road, evasive maneuver, and ran off road. It was concluded that there may be an opportunity for vehicle stability control devices to affect up to 48.5%of SUV rollovers.
