The Collapsible Crash Test Robot Car

The Collapsible Crash Test Robot Car

A lot of modern cars come with
advanced driver assistance systems, things like adaptive cruise control that
keeps a safe distance from the car in front or automated emergency braking
to avoid collisions or lane assist, to… keep you in lane. Which is great, as long as the driver
knows the system’s limits. The worst modern car I’ve ever driven
came with adaptive cruise control
that turned itself off if you went under 20mph. So if the car in front slowed
down for a traffic jam, so would you, until you went under 20, at which point the car just
handed control off to you with a very quiet beep. And if you weren’t expecting that… This is the Global Vehicle Target and, as of this year, it is
part of the EuroNCAP standard on how to test the safety of
automated driving systems. But it isn’t just a static foam model. This base here is a robot platform
that goes up to 50mph, which means you can test safely with
both vehicles going at highway speed. Right, my turn in the passenger seat. I mean, of the real car, not this. This doesn’t have a passenger seat. – Thatcham Research is a not-for-profit
insurance-funded research centre. In about 2014, it became clear
that the next generation of technologies weren’t just going to look for
the rear end of the car, they were going to look
at the side of the car and even the front of the car. We’ve got to have a target that actually
looks like a three-dimensional car. The impactable bit,
the visual pieces of the car, are actually foam target blocks
which are assembled to look like a car and covered with a radar material. Generally, you can put
the target, from start, back together in about 15 to 20 minutes. And what we’ve done is
we’ve used test equipment that actually measures the radar
reflectivity of a real vehicle. So you get radar reflectivity of a wheel. And even the glass, the back of the vehicle,
has a certain radar signature. So it’s about putting radar reflectors and also radar-absorbent material
in the right place. So the brand-new tests that
we’re going to introduce in 2020 are what we call turn-across-path, where your vehicle is moving
in front of another vehicle and we want your vehicle to brake. We’re also developing junction tests where a vehicle moves
across your path laterally and therefore we need
to see the side of the vehicle. And we’re confident that if a
vehicle brakes for our target, it’ll brake for a real vehicle
in the real world. – This should stop in time? – Yes, yeah.
– OK. All right, let’s do it. [alarm chiming] [braking system rumbling]
– Whoa! First of all, that works. That’s good.
– Yep, we have stopped. – Oh, that made me feel so nervous. – It’s deliberately late and harsh. – Radars are very good at understanding
if something is moving. They can identify what it is. However, if you just come across
an object and it’s stationary, it’s much harder for the radar
to identify that that’s a vehicle. What’s the difficulty is understanding:
has the driver seen it? And what are the driver intentions? So if you’ve got a vehicle
that’s parked in front of you, it doesn’t want to warn you too early, because that’s gonna annoy the
driver and we don’t want that, because if your driver is annoyed, he’ll turn the system off. One of the problems vehicle
manufacturers have is there are not only differences
in the road infrastructure, but there’s actually
national characteristics. People in Germany tend to drive
slightly more aggressively. And, therefore, the
issue of false positives, it’s much more of an issue. Whereas the Swedes will tell
that they’re much more benign and, therefore, a vehicle
that’s just stationary, warning the driver won’t
really annoy him too much. – OK, so what happens if
we go slightly faster? – Well, we’ll try it, and
it should be, you know… We’ll do 40mph rather than 35. – All right. (Oh, I don’t like this.) I really don’t like this. [alarm chiming] [braking system rumbling]
– Ohhh! [alarm chiming] Does it slightly brake to warn you? – Yes.
– Yes. – You hope, with that little brake,
it’s enough for the driver to go, oh, this is…
something strange is happening, – Yeah, yeah.
– and do it themselves. – OK, yeah, that works. So does the target! – Yep, yeah. – Thank you very much to all
the team at Thatcham Research. Pull down the description
for more about them and their work. Wow! There is one tyre upright, just there.

  1. the real question is , can you put a chair on the platform and drive around using a controller? imagine a lawnchair driving past you on the highway

  2. As a biker, do they also test detection of motorcycles? I don't want the roads to be full of people trusting their car to prevent a collision and thus not paying attention to me. Nowadays I get overlooked/ignored on a regular basis already!

  3. While the radar reflective foam is interesting I'm most fascinated by that little platform. It's almost flat but can travel at highway speeds and endure being constantly run over.

  4. Why do you use MPH primarily instead of km/h? Use metric and/or SI units please. You can subtitle the MPH for the small remainder of the world that still uses the imperial system.

  5. Have you noticed that the license plate reads "WOB", which stands for Wolfsburg (in Lower Saxony), but the seal is Bavarian? What's up with that?

  6. 2:29 the wheel – is this some sort of key-frame anomaly/rolling shutter correction in post or something going on with the camera sensor? weird

  7. but… shouldn't the vehicle stop regardless if the object infront is a car? Would it want to go straight through a wall or a crowd of people?

  8. I can see in the future cars coming out with built in doppler radar that can warn you if you are approcing a twisting/dangerous storm and recomending you to take a evasive action by showing you the safest road to escape the storm….or to direct you to a nearby shelter.

  9. 2:32 that sound is way too nice. It sounds like you got a message on your phone, not like your car is about to slam on the breaks.

  10. Could they not have done it so that the foam car doesn't fly apart into a billion pieces, but just a couple instead? Maybe the individual pieces could be collapsible too so it only stays upright if all pieces are there, so it's easier to transport? The effort of gathering that all up and putting it all together is reeeeally dumb.

  11. Tom… What the everloving frick is going on at 2:30 with the wheel?
    The inner part of the rim is seemingly just stuttering a bit but the outer part seems to lock up.
    The inner bit looks like a rotor almost synching up with shutter speed, but…. shouldn't the outer part be connected to that!?
    What is going on?

    I mean i guess it has something to do with the inner part having a different number of distinct features, so each time we see an outer rim spoke pointed directly at the camera, you'd see the inner bolts and nuts holding the wheel in place in a slightly different position.
    But that doesn't really explain why the outer rim part, the spokes, seem to perfectly synch up and then be at a different position for another few split seconds, again perfectly synched up.

  12. Europe: lane assists, adaptive cruise control, blind spot indicators, alley cameras, proximity detectors, back-up cameras, and emergency braking are required by law in accordance with the European Transportation Safety Council for modern cars
    America: We just call those "extra features."

  13. Stupid that they take into NCAP and they Sant to make it mandatory. Over time, cheap affordable cars become more and more expensive and complicated for something I don't need if I am aware of the physics of a Car and people who don't know have to learn instead of creating a bubble around them.

  14. From 2:29 to 2:32, if you pay attention to the wheel in frame, it appears as though the scene has a whole bunch of jump-cuts, even though it's clearly one continuous shot. Does anyone know what is happening here?

  15. Wait why do you have to have radar reflective material. If there is a sudden obstruction on the road like maybe falling debris or the car car goes of road it won't stop?

  16. I want my next car to be built like that, so every time some idiot hits me I can simply strap the car back together.

  17. All these automated controls are bad. Drivers need to pay more attention to what's going on around them and this hand holding rubbish only encourages them to do the opposite.

  18. Um, so radar can't tell if the object sitting unmoving in the middle of the road is car or not? It's an unmoving object in the middle of the road! It doesn't matter if it's a car! You don't want to hit it!

    And two eyes are better than one.

  19. "This base here goes up to 50mph, so Highway speeds"
    Me: Laughs in German, proceeds to drive away at 150mph legally

  20. I was a little bummed to see them focusing on a single technology: radar. The test car should be compatible with any type of detection as to not limit innovation.

  21. So at 35mph it pulled up just short.. at 40mph it gave it a bump… so at 45mph what happens? Harder bump? What happens at 60mph?
    It's not that I don't think the system can work but showing it fail is probably not a good way to convince people of that!

  22. At the end it still hit the target car with enough force to cause at least $5,000 worth of damage to BOTH cars. Lets also not forget. What would happen if the road was wet or icy?

  23. awesome, awesome, very cool. Now where can I get one of those robot platforms? I'm asking for a friend, definitely not for an armored car heist.

  24. Safer cars are not making driving safer. They are making more dangerous drivers who think that their cars will save them. That's why there are still so much crashes.

  25. Self driving cars is an incredibly stupid idea, if you want to be a passenger get on a damn train or bus. Computers are set and stuck in their algorithms, they can't make judgement calls like a human can. Until true AI( we don't want that) is developed, the self driving car is a useless money pit idea.

  26. So a self driving car that uses radar comes across a car that has radar absorbent coatings ( used by cop avoiders) what happens then? There is an entire market based on nullifying radar, seems as if the scientist have tunnel visioned this project straight into the wall.

  27. In Tesla's technicality, the crash test robot car didn't collapse, it just disassembled itself out of the way of the moving vehicle!

  28. I love your videos but they are so short i dont feel like you have enough time to satisfy my interest in whatever the subject may be, I usually go find a longer more informative video on the same subject after watching yours
