Abstract: Since the launch of sport utility vehicle, it has been deeply loved by automobile consumers because of its power, trafficability and comfort of off-road vehicles. Subsequently, the prominent safety problems have attracted more and more attention from major automobile manufacturers and consumers. Relevant data show that compared with other types of vehicles, SUV is more likely to have rollover accidents. Moreover, compared with other types of traffic accidents, rollover accidents have a higher casualty rate, and have become a major cause that can not be ignored to threaten the safety of people's lives and property.
