Electric power steering (EPS) is an advanced steering system that uses an electric motor to provide steering assist. Being a new technology it lacks the history of conventional steering systems. Also conventional systems cannot be used to command an output independent of the driver input. In contrast EPS, by means of an electric motor, could be used to do so. As a result EPS systems may have additional failure modes, which need to be studied. In this paper the authors will consider the requirements for fail-safe operation. Strategies and procedures are proposed for classification of potential system faults into failure modes. The results of this paper have been implemented in various EPS-based programs.
