      +Awesome Aasim It's not used in lieu of crash tests - in fact it can't be used for crash tests! It's used for crash AVOIDANCE systems. No one would be stupid enough to use this thing for crash tests.

      What you need for your motorcycle is that foam model so you could wear it as a cape! It'll be strapped to the top of your head like one of those umbrella hats.
      No but genuinely, these things are also looking out for pedestrians. I think a pedestrian clinging to a moving hunk of metal would be recognized just as easily.

      I'm surprised you were so nervous. It was a foam model! I mean, if you did actually hit it at high speed, the car would go right through, so who cares!?

    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.

    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.

    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!

  • ShellShock794
    ShellShock794 5 months ago

    This video is really well done and put together but this company seems like they're full of crap.
    We don't see the target move and there is no way those velcroed pieces hold together while in motion, the car clearly fails the 40mph test, having a deliberately delayed/harsh brake is a fantastic way to give the driver no time to react and get rear ended.
    Nobody wants to admit it but automated cars are ridiculous and impractical. Not to mention no one wants them.

    • lewis waugh
      lewis waugh 4 months ago +1

      The platform has been in production for years and is used by the majority of OEMs and test centres around the world. Check out AB Dynamics TVclip page for loads of videos on it.

    • Tappits84
      Tappits84 4 months ago

      They were just saying the platform can move, but the tests they are going to do are not for 1-2 years yet and there test car, the volvo does not have the software to do it yet.. It's more of a soon ™ kind of thing.
      They were just showing they have made the destructible car thing that mimics a real car so they can test the new types of systems that are been developed and with it. it's quick and easy and cheap to do test after test.
      I don't think you understand how strong Quality industrial velcro is, More than enough to hold the car on the platform at 50mph
      As for the failed at 40mph, It's not meant to totally stop the car from hitting in any situation, hitting at 10mph is better than not having the system at all and hitting at 40mph.
      The test shown has nothing to do with automated cars and has to do with cruise control systems which have been a thing in cars since 1958
      Also i would love an automated car.

      Its not made to fix all problems, Most crashes are at less than 100kph were this system would help or avoid.

    This is what I've said for years. A computer can easily calculate and compare speeds, and determine acceleration and figure out when two items at different speeds and accelerations will collide. - It's about inserting these values into the computer correctly. - With these values, the car can then make sure you always have enough space to break before hitting the car in front, and if the car in front slows down, so will yours. (2:30) The car needs to detect that the item ahead isn't moving, and slow down your car much earlier for a safter stopping distance. It can be slippery too, and it should also be comfortable. (2:55) It doesn't need to understand that it is a car; it is huge and it is blocking the way. So would this car just run straight into a container because it isn't a car? (3:05) It doesn't have to alert the driver that it is braking; or at least not with sound. It can have an indicator that it is auto-braking, just like it has ABS and TCS indicators.
    There's no reason to turn this system off, but if needed, there can be an override; examples are if you are overtaking and don't want it to slow down by the car you're going to overtake, and if you're pulling out of a queue and the car thinks you're going to get to close to the car ahead. - As self driving cars is the future, the goal is to make these assistive features take over your car. - It will slow down when needed, it will keep inside the lines, it will park for you, and it can read signs, and it has a GPS, and so on.

    My car's cruise control shuts off if it goes below 29 mph. Doesnt really matter since I never use cruise control anyway. It is not a comfortable feeling (especially for my foot) having the car accelerate itself.

  • geekskates
    geekskates 5 months ago

    As a motorcyclist, this tech and the developing driver reliance upon it scares me. You wouldn't consider the second test that impacted the stationery vehicle to have worked if you were on a bike. People are already far too complacent when driving, checking their phones and not taking it seriously, believing an airbag will save them if it all goes pear shaped. Get rid of it all and provide good driver training and a Tullock spike in every vehicle.

    • Tappits84
      Tappits84 4 months ago

      Its not a driver reliance system. Its a system that makes using cruise control safer. Normal CC systems will just drive right in the back if the driver is not paying attention, were as this system will make CC safer by slowing or stopping you totaly. Most people dont use CC so makes no differance.

      We could, but what about people with disabilities that make it difficult or just impossible to drive cars?

    "Brake late because otherwise it will just annoy the drivers". What about countries up here in the north that occasionally have snow or ice on the road. I hope they put that up for a discussion, cause these break tests would have ended badly on slightly worse road conditions than we saw here.

    I know teslas have a mechanism for seeing two cars ahead by bouncing radar under the car in front of you. Wouldn't having the test target on a base with so little ground clearance give inaccurate readings with a system that expects a gap at road level?

    • lewis waugh
      lewis waugh 5 months ago

      The base is only 100mm high and the target has radar absorbing lower edges which offers minimal radar reflection, although I've not come across a sensor that looks under cars for further traffic.

    There's an interesting shutter sync artefact at 2:29. Every five frames the alloy wheel "spokes" (which are otherwise in sync with the frame rate) jump, suggesting there's a slightly longer or shorter interval after every fifth frame, than otherwise. What camera was used for that segment?

  • David Buschhorn
    David Buschhorn 5 months ago

    I used to drive a delivery truck on Fridays. It was about 700 miles of almost all highway driving. It was incredible what your brain wouldn't let you see! There'd be stopped traffic on the freeway and you would almost never be aware of it until it was really close. Like the distance where you realize you need to change lanes to get around a slower car.
    One stopped car in the middle of the road and cars would only hit their brakes at the last second. After that, the huge crash caught other driver's eyes and they'd slow down in time, but until then, that car in the middle of the road was definitely going to get hit. :-(

    What happens with such braking assistants if friction is worse due to rain, gravel etc.? The braking distance can easily be twice as high.

    • Oskar Skog
      Oskar Skog 5 months ago

      You don't. You can measure the friction when the wheel start locking or spinning, which may have happened already. Otherwise, you estimate the friction.

    • Michael K
      Michael K 5 months ago

      Oskar Skog How do you measure friction without applying a force i.e. accelerating (either positive or negative acceleration)?

    • Oskar Skog
      Oskar Skog 5 months ago

      They have to take measurements long before they even warn the driver.

    • Michael K
      Michael K 5 months ago

      Rob Fraser But how would they know about the friction before the brakes are applied? Or is the short brake pulse to wake up the driver used to get an estimate?

      I imagine cars will have redundancy's, Volkswagen are developing radar while Google and Tesla both use cameras and AI but I reckon best practice policy will see all autonomous cars one day using every feature that is available to them in exactly the same way we see cars using both seatbelts and airbags instead of choosing one or the other.

  • MagicSkeleton
    MagicSkeleton 5 months ago

    This is all very encouraging. What could be great is if cameras/radar were installed on light poles, watching all the pedestrians (not recording or identifying anybody). Then AI would be calculating probabilities based on movement and speed whether someone was about to walk or run onto the road. All cars could be required to constantly interact with this AI, so that if, say, a child was running around erratically on a pavement, the AI could judge there was a 70% chance he could run into the road, and, based on his distance to the road, your cars' distance to him (plus speed), could prime the cars' brakes and steering.

    • MagicSkeleton
      MagicSkeleton 5 months ago

      No, that's not what I'm proposing. I'm proposing sensors or cameras on every lamp post, all connected to a central AI controller. It's not surveillance, which I made clear in my original comment. There would be no recording or ID'ing of people. Just movement prediction to prepare cars for evasive action. The car and driver would be ultimately responsible for what happened, but the AI would prime the car if it deemed a certainly probability of danger. And it would be worth all the money thrown at it if it would save lives.

    • KohuGaly
      KohuGaly 5 months ago

      The real question is, where should the money be spend for best effect on lives saved. What you are proposing is a large-scale integrated surveillance system - such things are ridiculously expensive. On order of magnitude they are similar to establishing no-driving zones and public transport to them, which would eliminate 100% of car-pedestrian encounters.

    • MagicSkeleton
      MagicSkeleton 5 months ago

      Of course the driver should be aware, but pedestrians are still killed all the time (whether it's their fault or the driver's). The point is obvious: investing in AI infrastructure will give superior protection to pedestrians, and save hundreds if not thousands of lives.

    • KohuGaly
      KohuGaly 5 months ago

      interesting, but a bit of an overkill with high maintenance cost. The driver should already be aware of pedestrians at or near the road and estimate (the uncertainty of) their motion. Putting warning road signs in critical areas and making road and pavement more visible solves 99% of problems with just a chainsaw, pole, metal sheet and bucket of paint. And you can spend the money you saved elsewhere for better effect.

    In the future all cars will be driverless, and thus there will be less need for automatic radar breaks becasue the car in front of your car will just say "hey i'm going to stop how" and your car will go "okay, i'll adjust accordingly" for non car related accidents it will be useful though.

    • Rob Fraser
