Diagnostic Development for 
an Electric Power Steering System
ABSTRACT
Electric power steering (EPS) is an advanced steering system that uses an electric motor to provide steeringassist. Being a new technology it lacks the extensive operational 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 we will consider the requirements for successful EPS operation. The steps required to develop diagnostics based on the requirements are also discussed. The results of this paper have been
implemented in various EPS-based programs. 
 CONCLUSION
This paper has proposed a diagnostic strategy to help design appropriate operation for vehicles during steering related failures. A vehicle simulation model (E-SIM) has been developed for fault analysis. In addition, a highlevel diagnostic algorithm approach has been discussed.
The results of this paper have been implemented in various E•STEER™-based programs.
