Incorporating the computer simulation for steering systems developed to analyze fundamental static and dynamic performance of vehicle behavior in our previous report, the influence of mechanical components of the steering system and vehicle properties on maneuvering performance of vehicle is examined. We focused on reducing friction in the steering system to improve the state of yaw appearance. As a result of the analysis, it is shown that gear meshing friction has strong influence on steering performance. Based on this result, the design approach inherent for a steering gear is proposed. A newly designed gear was mounted on the vehicle and was evaluated by experienced test drivers to confirm its contribution to better steering feeling. Total simulation considering both steering and vehicle system behavior indicates that steering system affects mainly on yaw rate appearance and suspension system affects mainly on progress of yaw rate. These characteristics coincide with the feeling evaluation of test drivers.
