New Approach of Accident Benefit Analysis for Rear End Collision Avoidance and Mitigation Systems
Published October 12, 2011 by Society of Automotive Engineers of Japan in Japan
Approximately 31% of all casualty accidents in Japan are rear end collisions and OEMs as suppliers are therefore encouraged to introduce collision avoidance/mitigation systems to address these scenarios. Current strategies vary from simple warning over brake support to fully automated braking. Based on real world accidents sampled in Germany (GIDAS, German In-Depth Accident Study) and taking into account driver behavior, avoided collisions or reduction of collisions speed were determined in Germany. Then the efficiency of driver assistance systems was estimated before.
In this work, we transfer our results from the German market to Japanese accident situations, using data provided by JSAE (Society of Automotive Engineers of Japan). Accident avoidance/mitigation for different assistance systems show important benefits in Japan, taking driver behavior into account, ranges from 12% for warning up to 20% for automatic braking of all accidents with casualties.
