Test: Lexus Pre-Collision System(PCS) with pedestrian detection on 2016 GS350 F-sport
Just in case anyone is interested
Ran 4 tests at speeds 15-25 mph. All have failed.
Failed 3ft by 8ft cardboard test
Failed 3ft by 8ft cardboard test
EDIT: So I did some research on PCS and grew some ***** and tried it out on a real person (myself):
Successful real human test

It would be nice if we could see what the cardboard pedestrian looks like as I am not sure how lifelike this was. And no there are no IR sensors for this. It's all based on the front facing camera.

I think the camera and radar are designed to detect vehicles and pedestrians only. So if the object, like your cardboard cutout, doesn't resemble either a person (shape) or a vehicle (metallic reflections) the system won't recognize it and will "fail."

It's part of F-Sport package. Soon every car will have this technology in it just like ABS and seatbelts..

The way the system works is that it uses camera to recognize objects, such as vehicles and pedestrians. And it uses radar to compute density of the object. That's why even if cardboard looks like a pedestrian, it will not be recognized by radar. Check out this video:

The problem lies in false positives and how the system reacts. Back before independent testing, Volvo was a pioneer in production collision avoidance, but the IIHS doesn't rate their system so well. Volvo has tuned it a bit to reduce false positives, but the real question is -- did Volvo dampen it too much or did others design better for the test?
This tech is something you hope to never need and you hope it works when it is needed. Most of us will never test it intentionally.
