Integrated Vehicle-Based Safety System: Objective Test Scenario Warning Strategies: Kinematic Analyses and DVI Outputs

摘要

The Integrated Vehicle-Based Safety Systems (IVBSS) program is a four-year, two phase cooperative research program conducted by an industry team led by the University of Michigan Transportation Research Institute (UMTRI). The program goal is to integrate several collision warning systems into one vehicle in a way that alerts drivers to potential collision threats with an effective driver vehicle interface (DVI), while minimizing the number of excessive warnings presented to the driver. Basic program strategies for meeting this objective include systematically managing and prioritizing all information presented to the driver, minimizing the number of system false alarms, and restricting auditory alarms to higher urgency collision conditions. This report presents a series of analyses conducted by the DVI team on a subset of relevant driving scenarios to identify: the applicable warning algorithms, the corresponding DVI output, any potential ambiguities or conflicts in defining these detection algorithms and DVI outputs, and any potential issues in the time available to the driver to respond to the IVBSS warning.
