Devices, systems, and methods for testing crash avoidance technologies
First Claim
1. A soft body system adapted to form the body of a Guided Soft Target for testing crash avoidance technologies in a subject vehicle, wherein the soft body system is adapted to be mounted atop a motorized Dynamic Motion Element (DME) and when so mounted is adapted to collide with the subject vehicle while the DME is moving, the soft body system comprising:
- a plurality of panels each having an overall length, an overall width, and substantially uniform thickness, wherein the overall length and overall width are each at least ten times greater than the thickness;
the panels being soft and flexible, formed from one or more uniformly-distributed materials and having an overall hardness no greater than 100 Shore OO;
the panels being adapted to be removably attachable and re-attachable to each other at intersecting angles to form an interior framework of a Guided Soft Target, the interior framework adapted to support a covering that forms an exterior surface of the body of the Guided Soft Target; and
the panels being sufficiently rigid to be self-supporting when attached together to form the interior framework of the Guided Soft Target and when supporting the exterior surface covering of the Guided Soft Target, and when traveling at a speed just prior to the collision with the subject vehicle;
the panels and exterior surface covering being sufficiently yielding so as to detach from each other upon impact with the subject vehicle and sufficiently yielding so as to impart a minimal force to the subject vehicle upon impact, said force causing minimal to no damage to the subject vehicle.

Abstract
A Guided Soft Target (GST) system and method provides a versatile test system and methodology for the evaluation of various crash avoidance technologies. This system and method can be used to replicate the pre-crash motions of the CP in a wide variety of crash scenarios while minimizing physical risk, all while consistently providing radar and other sensor signatures substantially identical to that of the item being simulated. The GST system in various example embodiments may comprise a soft target vehicle or pedestrian form removably attached to a programmable, autonomously guided, self-propelled Dynamic Motion Element (DME), which may be operated in connection with a wireless computer network operating on a plurality of complimentary communication networks. Specific DME geometries are provided to minimize ride disturbance and observability by radar and other sensors. Computer controlled DME braking systems are disclosed as well as break-away and retractable antenna systems.
