The IVHS Countermeasures for Rear-End Collisions program's primary objective is the development of practical performance guidelines or specifications for rear-end collision avoidance systems. This work focuses on light vehicles only and emphasizes autonomous in-vehicle-based equipment. This Task 2 interim report presents the functional goals developed for three basic types of rear-end collision avoidance and related systems [Driver Warning System (DWS), Intelligent Cruise Control (ICC) System, Automatic Control System (ACS)]. In addition, the report presents the dynamic situations relevant to the rear-end crash problem. These dynamic situations allow the events leading to accidents, and accidents themselves, to be subdivided into smaller groups that can be addressed individually. To establish the functional goals, a taxonomy of collision subsets and crash-related events that provide a basis for identifying opportunities for intervention in the sequence of events leading to a crash was developed. The functional goals established for each of the system types is based on this taxonomy. The report also established the terms and definitions as they relate to this program. This is done to provide background into the rear-end collision avoidance problem and to standardize on definitions and terminology. The results presented in this report are based on a limited amount of work carried out with limited interaction with the academic, research, and industry communities. |
