Rollover Propensity Control Via Active Suspension for Off-road Vehicle

Abstract

A control strategy that improves rollover stability via active suspension is presented. The control structure is proposed considering the load transfer rate as the rollover propensity index. The controller is based on fuzzy logic and different stiffness on each active suspension limit the rollover propensity during cornering. Simulation results for off-road vehicle of fishhook test show that the proposed algorithm can effectively reduce rollover risk.
