Problems solved by technology

In either case, however, the dynamic capabilities of the balloon car or SSV will limit the tests that can be performed because if the balloon car or SSV moves too fast, they will deform, lift off, or otherwise behave differently than the vehicle

Embodiment Construction

[0027] Broad aspects of the invention include a system that allows a test vehicle with a collision avoidance system or other active vehicle control system to be tested in a manner crashes, accurately simulating real-world conditions without damaging the test vehicle or other components of the system. In addition to collision avoidance, the system can continuously repeat tests to allow precise comparisons between individual tests when required, evaluating test measurements against different operating parameters and / or components and / or collision avoidance systems or other active vehicles control system performance.

[0028] refer to figure 1 , taking the system 10 as an example to include an agile target 12 (herein, the agile target may be, but not limited to, a replica of a vehicle without personnel carrying capacity, or a replica of a real vehicle, or it may also be other common road vehicles such as pedestrians, bicycles, etc.), a test vehicle 14, and a wireless communica...

Abstract

A system and method for testing a test vehicle (14) or a system on the test vehicle (14) to warn of the presence of an object adjacent to the test vehicle (14) or system to avoid a collision, the system and The method includes positioning a self-powered, independently movable target (12, 12A-12G) adjacent the test vehicle (14), the target (12, 12A-12G) including a support frame, a motor (37), brakes (35 ), a control system, and an anti-collision system (40), the support frame has wheels, the engine (37) is operatively coupled to one or more wheels, the brake (35) is operatively coupled to each wheel , the control system is coupled to the engine (37), brakes (35), and wheels and is used to control the acceleration, braking, and steering of the wheels, and the collision avoidance system (40) can operate with the control system and is used to control the target ( 12, 12A‑12G) to prevent collisions with test vehicles.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority to U.S. Provisional Application No. 62 / 063,952, filed October 15, 2014, and U.S. Provisional Application No. 62 / 143,978, filed April 7, 2015, the contents of which are adopted in their entirety Incorporated herein by reference. Background technique [0003] Existing methods for testing active safety / collision avoidance systems for ground vehicles typically include a target vehicle. The idea behind a balloon car or crashable vehicle (SSV) is that if the test vehicle fails to avoid a collision, the test vehicle can crash into the balloon car or SSV, and then hopefully the test vehicle suffers only minimal damage . [0004] There are some notable drawbacks to balloon car or SSV testing. First, the balloon car is not a true replica of the vehicle as seen or sensed by a test driver sitting in the test vehicle or by sensors such as a radar unit because the materials and gener...
