In this test, the test vehicle (Volvo V60) turns across oncoming traffic. The driver sees one vehicle and starts to turn after the first vehicle has passed, but isn't aware that there's a second vehicle behind it. The Volvo is fitted with collision avoidance technology which detects the second vehicle and brakes to avoid a collision.
These tests can be done using AB Dynamics' soft target vehicles (SCT and GST) to avoid damage to the test vehicle.
This type of complex scenario is easy to create and run repeatably with AB Dynamics' soft targets and driving robots.
