Dynamic performance enhancement of vehicles with controlled momentum wheel system

Active yaw moment control is one the method in order to control the vehicle stability and improve its handling. In this method, a corrective yaw moment would be applied to the vehicle which can modify the dynamic behavior of the vehicle. This corrective yaw moment could be generated directly or indirectly and it would be a function of friction between tire and road. Therefore in low friction conditions, like icy roads, the ordinary yaw moment control system couldn't produce sufficient corrective yaw moment. In this paper a new approach which is inspired from aerospace technology is introduced to control the vehicle handling and stability. This innovative method uses a momentum wheel to produce corrective yaw moment which is independent from tire road interaction. The dynamic analysis of the model has been performed and computer simulation results for different road conditions are presented.
