Abstract
Future steering systems must not only be compatible with automated driving systems, but also allow for improved driving space flexibility. To address these needs, we are currently developing a Steer-by-Wire system with no mechanical link. This paper proposes a fully redundant configuration, the state transition and, a control method of variable steering gear ratio and reaction force to achieve natural steering feel in a Steer-by-Wire vehicle assuming driver doesn't change hand position on the steering wheel. Moreover, taking advantage of the characteristics of Steer-by-Wire system, we also demonstrate the effectiveness of a control method to transmit only necessary road information to the driver.
