The SUV has a risk of rollover because of the highness of center of mass in turning. The rate of traffic accident is not high, but it causes vital injuries for passenger and death rate is high on a slope than a flat. Although the study of design and control for rollover prevention to secure safety in driving are implemented, the information for roll-behavior of various road and driving conditions including the slope is insufficient and required necessity of these studies.
In this study dynamics model influenced by longitudinal and lateral angle of the inclination is considered in order to analyze roll-behavior of the vehicle in turning on a slope, it derives relations between forces acting on tires and roll angles, lateral accelerations and these behaviors and compares with the results of simulation. These analyses using ADAMS/Car that modeled the vehicle, 3d-road, driving condition at a constant velocity are performed, step or pish-hook steering and the variations of friction coefficient of the road, spring stiffness of suspension and the highness of center of mass are applied to the analyses. The results show that the relational expression between the ground force acting on the tire and the roll motion is well established. It is identified that the driving state of the vehicle becomes unstable at the lower or upper position of the slope, and the optimal suspension of the vehicle using taguchi method presents the improvement of roll-behavior.
