Abstract Our previous report described a theoretical method for improving steering maneuverability and effectiveness based on the performance of high-effi cient actuator and actual vehicle evaluation. The higher transfer-effi ciency is not enough to achieve expected steering maneuverability, and other element characteristics should be properly established. Steer-by-wire system is well known as an innovative steering system that has a potential to create fl exible transfer characteristics. This report describes advantages of the steer-by-wire system for improving steering maneuverability in comparison with conventional steering systems, and design and evaluation technologies of steering transfer system using a steer-by-wire system.
