Abstract:This report describes the assessment of the driver interfaces of a type of electronics-based collision avoidance systems that has been recently developed to assist drivers of passenger vehicles in avoiding certain types of collisions. The electronics-based crash avoidance systems studied included: those which detect the presence of objects located on the left and/or right sides of the vehicle, called Side-Looking Collision Avoidance Systems, or SCAS; those which detect the presence of objects located to the rear of the vehicle, referred to as Rear-Looking Collision Avoidance Systems, or RCAS; and those which enhance the driver’s ability to see the presence of objects located to the rear of the vehicle using video cameras (also called RCAS). As many side and rear collision avoidance systems as could be obtained, including several pre-production prototypes, were acquired and tested. The testing focused on measuring the performance of the systems’ sensors and assessing the qualities of the systems’ driver interfaces. The sensor performance data is presented in an accompanying report by TRW. One goal of this research was to evaluate, based upon the principles of human factors, how well the driver interfaces of the collision avoidance systems studied were designed. The strengths and weaknesses of each driver interface were determined. Overall, while none of the SCAS had an “ideal” interface, most of the systems had ergonomically acceptable interfaces. Not surprisingly, the commercially available systems tended to have better driver interfaces than did the prototypes. Another goal of this research was to provide advice to future designers of collision avoidance warning system driver interfaces as to ergonomically desirable or undesirable features. From the interface evaluations performed, the authors have developed a preliminary set of driver interface performance specifications that may be of aid to future SCAS driver interface designers.
