Vehicle steer-by-wire system (SBW) can improve the handling stability, passive safety, active safety and drive comfort significantly, which becomes a hot topic in research. However, the safety problem of SBW is one of the most critical problem in its practical application. In order to solve the safety reliability problem of SBW, a dual-redundancy steer-by-wire system (DSBW) is proposed in this paper by applying the redundancy theory, in which no system failure is achieved when any single random electrical fault occurs, showing that DSBW is a system-level dual-redundancy system rather than a system with local redundancy. Finally, a DSBW prototype is manufactured to prove its high safety reliability. Fault injection experiments of the system are performed, in which DSBW works normally when any single electrical fault occurs.
