Vertical Dynamics Control Using Active Tires and Preview

Abstract

In this paper, the effects of adding a tire actuator to a vehicle with active suspension and preview control are studied. For the controller, the LQR method is used. The dual actuator system with preview control is compared to other conventional systems to determine the performance gain. The results show a gain of 182.3% in comfort compared to the passive suspension. The dual actuator system with preview control outperforms systems with fewer actuators and is less affected by the trade-off between handling and comfort.
