A soft body system adapted to form the body and exterior surface of a Guided Soft Target for testing crash avoidance technologies in a subject vehicle is disclosed. 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 includes a semi-rigid form with an exterior surface. The form is sufficiently yielding so as to impart a minimal force to the subject vehicle upon impact. The form may be shaped like a vehicle or a part of a vehicle. The exterior surface includes a side skirt made of radar absorptive material (RAM), radar reflective material (RRM) or a combination of both, which is positioned adjacent to the ground and constructed to prevent radar wave from entering the soft body system.

The present invention discloses a method of filling simulated muscles for a limb of an automobile crash test dummy, the simulated muscles are molded with foaming in the inner cavity of the mold; the method comprises: obtaining a filling volume of the inner cavity of the mold by using a liquid casting method, preparing an adhesive liquid film layer, preparing a filler and conducting demolding detection on the limb. Wherein step 3 is to inject the mixed filler into the inner cavity of the mold so as to be foamed in the mold to form foamed sponge, and stand until the foamed sponge is foamed to the exhaust port and does not overflow any more.

The invention relates to a dummy object for testing the operationality of driver assistance systems or emergency braking systems in motor vehicles or rail vehicles. The dummy object is configured to be made to collide with a test object in a test of an emergency braking system, having a torso and at least one limb. The limb is coupled to the torso and is connected to be movable with respect to the torso by way of a first joint unit, and having at least one first electric drive unit. The first electric drive unit is configured to move the limb relative to the torso. It is provided according to the invention that the first electric drive unit forms an integrated structure with the limb.

The disclosure belongs to the technical field of autonomous vehicle, in particular to an automatic driving acceleration test method considering efficiency and coverage, which includes the following steps. Step 1 is definition of scenario test priority. Step 2 is zone division. Step 3 is search within zones. Step 4 is update of scenario test priorities. Step 5 is iterative test. After selecting the automatic driving function to be tested and setting the parameters of the vehicle operation zone, the scenario generation range is formed. The coverage of the test scenario is improved by dividing the generated range and setting the freedom of early autonomous driving exploration. The efficiency of the test process is improved by continuously improving the probability of generating dangerous scenarios in the test process. Thus, it is ensured that the generated test scenarios take into account both test efficiency and test coverage.
