Development of Performance Specifications for Collision Avoidance Systems forLane Change, Merging and Backing. Task 3. Human Factors Assessment of the Drivers Interfaces of Existing Collision Avoidance Systems

摘要

This report describes the assessment of the driver interfaces of a type ofelectronics-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.
