A modified skyhook control system (SKDT) to improve suspension control strategy of vehicles

In order to achieve the desired ride comfort, road handling performance and to solve the uncertainties, a new modified skyhook control strategy with adaptive gain that dictates the vehicle´s semi-active suspension system has to be presented. Recent works do not consider the effect of road bank angle or the dynamic model of the tilting standard passenger vehicles. The lack of incorporating road bank angle creates a non-zero steady state torque requirement. The paper addresses these issues. The paper introduces a proposed skyhook control system (SKDT) along with direct tilt control which demonstrates that the integrated suspension control strategy can be used to tilt a vehicle inward to act against the lateral acceleration due to steering maneuvers. The designed SKDT system was observed to improve the isolation of the vibration and handling performance and stabilize the tilt mode of the system by keeping the vehicle stable and safe from rollover.
