Legform Impactor Tests Active Safety Systems

June 22nd, 2007

TRL has released a new ‘biofidelic legform impactor’ for use in testing and assessing contact sensor technology used in vehicles’ active safety pedestrian systems. The new legform will enable vehicle and component manufacturers to accurately test and evaluate new systems designed to reduce pedestrian head injury in the event of a impact.

Based on research data the legform resembles as far as is possible a human leg in terms of flesh density, while the bone material has properties that will enable fractures to occur with sufficient loads.

The aim of the new impactor is to replicate a vehicle impact with a pedestrian in order to ensure the vehicle active safety system deploys to reduce the risk of injury to the pedestrian. Conversely, the system needs to differentiate between pedestrians and other objects, such as animals or road debris, to avoid unwarranted deployments.
