A Novel Evaluation Methodology for Combined Performance of Warning and Braking in Crash Imminent Braking Systems

Crash imminent braking (CIB) systems are equipped in high-end passenger vehicles by many auto manufactures. Due to the complex nature of the CIB technology, the features and performance of various CIB systems differ significantly. To date, there are no standards to evaluate and compare the comprehensive performance of different CIB systems. This paper describes a systematic methodology for the evaluation of CIB systems which include both warning and braking features. The percentage kinetic energy reduction is a measure used in the performance evaluation. The information collected from some ongoing vehicle active safety testing projects will be used to validate the proposed methodology.
