Enhanced Camera/Video Imaging Systems (E-C/VISs) for Heavy Vehicles

Tests were performed to determine the feasibility of developing an Enhanced Camera/Video Imaging System (Enhanced C/VIS or E-C/VIS) to provide heavy-vehicle drivers with better situation awareness to the sides and rear of their vehicles. It is well known that large blind spots currently exist in these areas and that sideswipe crashes can occur as a result. An additional goal was to extend the operating envelope of conventional video to nighttime and to inclement weather. A three-channel system was envisioned in which there would be a camera at each (front) fender of the tractor looking backward along the sides of the rig. The third channel would be aimed rearward from the back of the trailer. The current document describes the project results. Indoor tests involved selection of components having the best capabilities, while early outdoor tests used the selected components in a single-channel side mounted system. Subjects evaluated rain and dark conditions. Results were satisfactory. Once developed, the three-channel system was tested and found to work well in the nighttime and inclement weather environments. Street lighting was also included in the testing.
