Abstract

The University of Texas at Austin Center for Electromechanics has developed an active suspension system that recovers, stores, and manages energy while actively controlling vehicle suspension activity. Tests described in this paper quantify increases in rolling resistance from flat to rough terrain, and demonstrate that active suspension systems limit this increase to 50% of that experienced by passive suspension systems.
