An Examination of EPS using Cables to Connect the Steering Wheel and Gearbox 2003-01-0584
We examined Electric Power Steering (EPS) for its benefits in increasing space in an automobile passenger compartment, particularly access to the driver's seat. Some automobile models offer better access than others, but no models offer particularly good access. We analyzed driver motions during ingress and egress and parameters which affect access to the driver's seat were identified. The relationship between the ease of access and those parameters were then examined with respect to posture. The affect of the presence of the steering wheel was also examined. As an achievement means, we proposed a flexible EPS structure which is connected by cables between the steering wheel and the gearbox. This paper describes the design concept of Cable-Based EPS and outlines the components offering steering performance and reliability, and its effectiveness.
