The potential of contollable suspensions in directly affecting yaw motion of a vehicle is analyzed and tested. Continuously variable magneto rheological (MR) dampers and active roll bars are used to distribute the roll resisting moments between front and rear suspensions, so as to bring the actual (measured) vehicle yaw rate as close as possible to the desired yaw rate. The available control authority for each of the suspension systems, in terms of ability to generate corrective yaw moment, is evaluated. The results of simulations are then presented for vehicles equipped with MR dampers, active roll bars, and both. The effects of transient and steady state roll couple distributions on vehicle yaw response are examined using open loop and closed loop yaw control. Finally, the results of simulation and demonstrate benefits of the proposed control method, in terms of improved emergency handling, stability, and reduced driver steering effort.
