This paper describes the research of rollovers of passenger cars and proposes a ramp type test as a typical dynamic rollover test with evaluations of occupant injuries and vehicle deformation in accordance with various parametric functions. Many types of rollover tests have been conducted in the past and they have their merits and demerits. However, the ramp rollover test has a characteristic to evaluate both dummy injuries and vehicle deformations, and to perform tests under many conditions by exchanging ramp dimensions, steer timings made rotation and velocity of the vehicle.
