Predictive safety for pedestrians The future of the automotive
industry is being shaped by developments such as predictive
pedestrian protection. Yet before the first models can actually
be equipped with intelligent systems to prevent collisions, the
necessary sensors must first be tested in realistic conditions.
To do this, a pedestrian dummy installed in a test rig is pulled
out of danger at the last second with a force of over 14 g.
These test rigs are developed and built by 4a engineering GmbH
and rely on control and drive technology from B&R. Hoisting the
dummy up and out of danger protects it and the vehicle from harm
and is one of many technological challenges in this
sophisticated experimental design. The system itself was
designed and built by 4a engineering, a technology-oriented R&D
company based in the Austrian town of Traboch that specializes
in developing and optimizing new products and procedures through
a profound understanding of physical and mechanical processes.
Hence, the 4a motto: "In phy
