Due to the lack of the definition of a generic buck for full‐scale car‐pedestrian impact tests, it was not possible to develop standardized trajectory corridors for validating the biofidelity of a full‐scale pedestrian dummy in whole‐body kinematics. The objective of this study was to validate the buck representing sedans developed by the authors’ group against cars in the sedan category at the full‐scale level in terms of the representativeness of car‐pedestrian interactions.

Full‐scale lateral impact tests were conducted using the buck and the POLAR II pedestrian dummy at 40 km/h, and the tests were simulated using FE models of the buck and the pedestrian dummy to validate the buck model at the full‐scale level. The validated buck model was used to simulate a car‐pedestrian lateral impact at 40 km/h using a human FE model previously developed by the authors. The representativeness of the buck was validated against a combined dataset from five FE models of production cars and estimation of APROSYS (Advanced Protection Systems) data representing the sedan category, showing that the trajectories, contact forces and injury measures from the buck model generally fell within their variations among the cars in the category represented by the buck.
