Pedestrian protection technology has drawn considerable affection. Three sub-system tests have been proposed by EEVC/WG17 to evaluate car front aggressiveness: legform to bumper test; upper legform to bonnet leading edge test; and headform to bonnet top test. In addition, a pedestrian full-scale dummy has been developed to evaluate the kinematics of a pedestrian. However, the differences between the sub-system tests and the full-scale dummy test have not been clarified yet. The object of this study is to clarify the differences by comparing the results of sub-system tests and full scale dummy tests on the same impact condition in a compact car. A typical compact car was selected and several kinds of car front specifications were implemented. A series of tests with combination of two impact speeds, 25 and 40km/h and several car front specifications was conducted using three impactors proposed by EEVC/WG17 and a full-scale dummy. A POLAR dummy developed by Honda R&D Co., Ltd. and GESAC was used. The kinematics were compared by video analysis. The head accelerations, the accelerations and loads of femur, leg and others were compared by electronic measurements. It is clarified how the results of sub-system tests and full-scale dummy tests have been influenced by the difference of impact speed and car front specifications.
