Abstract

To ensure drive's field of view, obstruction area generated by a steering wheel, hub and spoke must be considered at the early stage of automobile design. The current approach to computing obstruction area proposed by SAE is based on 2D drafting procedures so that it is not precise and errorprone. In the paper we discuss the novel approach which models the obstruction area as the shadows of the steering wheel, hub and spoke by assuming the human eye as light sources. The approach is based on ray tracing and space transformations for that it can be applied when free form curves are hired to represent the steering wheel, hub and spoke in CAD environment. As a result, it gives more predise and reliable results than SAE approach.
