Camera-Based Indirect Vision Systems for Heavy-Duty Vehicles – Phase I

Indirect vision systems are used by drivers to identify objects that do not fall directly within their line of sight. This can be accomplished through the use of a conventional mirror-based indirect vision system or by a camera-based indirect vision system. The purpose of this study is to evaluate the design factors surrounding the use of camera-based indirect vision systems, quantify the possible fuel savings which may be achieved through the use of such systems and to identify and quantify any secondary effects related to their use.

The design factors were separated into human design considerations and equipment design considerations. The two categories of design factors were evaluated through a literature review of past similar studies as well as other pertinent journal articles and texts.

The possible fuel savings which may be realized through the use of a camera-based indirect vision system were quantified by performing full-scale component testing in a 2m by 3m wind tunnel. The results of the component testing were compared to previously performed full-scale vehicle testing in order to determine the overall reduction in the vehicle drag coefficient expected through the use of a camera-based indirect vision system and, in turn, the possible fuel savings.
