Rollover

In most accident situations, an effective rollover protection system has to detect the impending rollover early on and activate the systems that will effectively limit the impact of swinging motions on the vehicle’s occupants and the risk of occupants being thrown out of the vehicle.

RolloverContinental relies on intelligent networking of computer calculations and testing.
The process starts with vehicle dynamics calculations using ADAMS. In this step, rollover risks are determined depending on parameters such as the condition of the road surface, the geometric structure of obstacles, and the vehicle’s speed, direction of movement, and load status.
Then, vehicle occupant simulation is used to determine the parameters for the restraint systems and the optimum actuation times. Critical driving maneuvers are analyzed during testing in order to improve vehicle models and generate data for algorithm development.

Because the majority of the parameters that exert an influence on these cases cannot be covered by testing, the further rollover data needed for algorithm development are generated by means of numerical simulation.
Typical rollover behaviors that our computations and testing consider include corkscrewing, embankment rollovers, curb trips, pitchovers, and soil trips. The latter type of testing can also be performed, by customer request, with a phase of skidding caused by steering and braking maneuvers.
