Abstract
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.
