Steer-by-Wire (SbW) is a newly emerging technology entering the market in the next decade. The additional degree of freedom in the steering system leads to not only new and enhanced features, but also opens up numerous questions how the system needs to operate in specific situations to satisfy the driver. These situations encompass events where the separation of steering wheel and road wheels may lead to unique behaviours when compared to traditional steering systems. To better understand these use-cases, Ford Motor Company conducted multiple customer clinics as well as expert studies to define the requirements of the SbW system. One key question to be answered was, if a SbW system requires an electro-mechanic locking device to prevent misalignments between steering wheel and road wheel position. Other items of interest are feedback actuator sizing and strategies to mitigate hand and road wheel misalignment. This paper describes how a preliminary set of requirements were derived for Steer-by-Wire system to function without a feedback actuator locking device. Special attention was given to minimize system sizing and power consumption while achieving customer satisfaction.
