The rollover process is complex. Most of the existing researches focus on the rollover monitor and control. But thewriter of this paper think that rollover warning and prediction can reduce theaccidents which were caused by human operation effectively. In order to optimize vehicle configuration,and enhance vehicle rollover stability,and ensure the road safety,rollover model is proposed .Besides, the reasons that have effect on rollover are analyzed in detail. The final result can provide a scientific basis for the optimization of the vehicle’s structure and improve the stability of vehicle rollover.Furthermore, some active control systems with rollover prevention are analysized and proposed. At last, the effective control system and the project how to achieve it are provided. This paper mainly introduces the static rollover test bench of automobile structure design and calculation，to make the measured motor performance parameters for driving safety, more convincing.
