AB Dynamics, a supplier of automotive test solutions, in collaboration with sister company Dynamic Research (DRI), has launched the child version of its pedestrian advanced driver assistance systems (ADAS) target, the Soft Pedestrian 360. This new target aims to address the increasing demand for child pedestrian testing, focusing on realism and reducing test downtime.
Jordan Silberling, general manager of DRI, highlighted the growing need for child pedestrian targets due to expanding Euro NCAP test scenarios. “Following the success of the adult version of our Soft Pedestrian 360, we have seen an increase in demand for a child target that caters to these test scenarios and uses the same proven architecture and technology.”
The new child target shares the modular architecture of its adult counterpart, designed to minimize the mass of any component that could potentially damage the test vehicle. The servos operating the articulating legs are encased in foam within each component, eliminating exposed hard points that could impact the test vehicle. This design aims to ensure that the vehicle under test is protected when the limbs disconnect upon impact.
Silberling emphasized the importance of reducing downtime during testing sessions due to vehicle or target damage. “Our goal is to help avoid unnecessary delays, ensuring efficient testing,” he commented.
To further minimize downtime, the child’s limbs attach to the body via foam blocks that engage corresponding sockets in the torso, allowing the leg subassembly to be changed in under a minute. The target also uses a novel slipper clutch, preventing servos from being back-driven during a collision, which improves durability. The cross-compatibility of components helps reduce overall testing costs and the need for storing spare parts.
The child version also uses durable fabric clothing similar to the adult version, maintaining a consistent shape throughout testing and protecting the foam core from wear and tear. The clothing is easily replaced if damaged.
