EEVC/WG10 proposed three component pedestrian subsystem tests. Pedestrian subsystem impact tests with production cars have been conducted in Euro-NCAP according to the EEVC test method. From the Euro-NCAP the upper legform impact test has the most difficulty fulfilling the current injury criteria. However, recent accident analyses indicate that the priority of the upper legform test seems to be the lowest in the three EEVC subsystem tests. The objective of this research is to validate the test conditions of the EEVC upper legform impact test using computer simulation models. There is a possibility that the impact energy defined from the EEVC look-up graph may include significant errors. The values of the EEVC impact energy can be decreased about 30% for cars with a 650mm to 750mm bonnet leading edge height. It is not necessary to use an impact velocity look-up graph which should be calculated directly using a specific impactor mass and an impact energy defined from an impact energy look-up graph. (A)
