Vehicle Rollover Avoidance

This article presented an overview of vehicle rollover testing standard and control development. Government testing procedures are first described. Necessary vehicle state estimation for rollover control is then developed. An energy-based RDI is then investigated. Finally, a control strategy based on state estimation and the RDI is developed and verified in vehicle tests. A 1DOF vehicle model, together with standard inertia sensors for the stability control system, provides state estimation needed for RDI and rollover avoidance control.
