How Automobiles Work


Hello everyone and welcome. In this video, we’re going to be talking about
Honda’s new motorcycle technology, which they call Honda Riding Assist, which is
used to help prevent the bike from falling over. And now, usually something like this would require
gyroscopes, but Honda’s solution is actually really simple and doesn’t use any gyroscopes at all. So, if you think about sitting on a bike, or a bicycle
in this example, basically, you don’t really have any tools to help hold you up except, you know,
shifting your weight, and then of course you can change the location of where you turn the handlebars. And so as you turn the handlebar, that’s the exact same
tool that Honda is using in order to help their bikes stay upright. Now, in order to understand how this technology
works, we need to talk about trail length. So, there’s two different trail lengths we’re going to be
talking about: positive trail length, and this is where the streering axis on the bike lies ahead of where the
center of the tire is, and this is good for sporty riding, this is good for pretty much any riding at speed.
And then there’s something called negative trail length, and this is where the streering axis
will lie behind the center of the tire. And so this is good for super low
speeds to maintain stability. And so what these do is change how the bike
moves when you pivot that streering axis. And so if you turn to the right with positve
trail length if you turn that bike to the right it’s going to want to turn into that,
and fall into that corner. If you turn a negative trail length bike so you’re sitting
on a bike like this, you turn the wheel like that it’s going to want to push you out this way. And so to understand how that works,
we’re looking down on top of the tire. So there’s our center point that’s actually touching
the ground, and if you have positive trail length, that means your pivot point is going to be up here,
so if you were to pivot up here, that’s going to want to push that center this whole tire
this direction, and so, obviously, if you’re pushing the tire out that direction, it’s going to
want to make your bike fall over this way. So you turn the bike in, it pushes the bike
it pushes the tire that direction and you fall over. The other side with negative trail length, if you have that
center there, you’re pivoting the tire this direction, so your’e going to try to turn it like that.
You’re going to try to push the tire that way, rather than, like, this way and so that’s
going to push your bike, of course, that way. And so if you’re starting to fall over this direction, and
you turn the bike in you turn those handles in you’re going to push yourself back up. So a very simple demonstration here
using a coaster and a sheet of paper. You can see that if we have positive trail length,
so the pivot point is ahead of the center of the tire. If I rotate that, it’s going to move the
sheet of paper to the left. If we have negative trail length, so the pivot point
is behind the center of the tire and you rotate it, you’re going to move the sheet of paper to the right. So this is what Honda’s actually doing with their bike.
So they’ve got a simple setup. Here, you’ve got a variable sight angle system,
which extends the front of the bike out. You’ve got a steer by wire system for low speeds and
you’ve got the streering motor so that the computer can take over control. So the process is very simple. At low speeds, your
handlebars are going to disconnect from the streering and a computer is going to take over
and do those minute adjustments for you. So if the bike starts to tilt, it simply turns that
wheel into that direction that the bike starts to fall, and it maintains the bike upright,
so that it doesn’t fall over. Now, this is a pretty cool technology and I can almost
already read the comments of people saying, you know, “this is for people who have no
idea what they’re doing,” but I can certainly think of scenarios you know, if
you’re older, if you’re shorter, or if you just have a really heavy bike and you still want to ride and, you know,
these things are working against you, there are certainly scenarios in which this can be
beneficial and help make it easier for people. When you’re standing there at a stop light or, you know,
crawling at slow speeds in traffic and you don’t want to worry about putting your foot
down or things like that. You know, depending on if you’re older,
shorter, etc., how heavy the bike is… So I can certainly see the benefit of a system like
this and it is really cool how simple the system is. So thank you guys for watching, and if
you have any questions or comments, feel free to leave them below.

  1. Regardless of its application today, right now, this has some great potential uses and applications in the future especially in combination with other systems and the coming age of the self-driven automobile.

  2. I love the fact that we are working to build these awesome bikes but as a rider this is so unnecessary but you never know this might lead down another path that is awesome lol

  3. I know a great use of this technology.
    Self driving bikes.
    They've already started the process, the bike knows how to follow it's engineer.

  4. there smart we are not they make all the cool stuff in America we make nothing which will lead to our demise

  5. How expensive is the system? Will it be in hondas standard production bikes any times soon? Or just afuture concept bike?

  6. what a boring motorcycle, if you can't fall what's the fun about riding? anyway, wasn't it adorable when the bike followed the pilot like a doggy?

  7. Why can't you achieve the same thing with a positive trail length just by steering the opposite way of the way you're falling? It seems to be the same effect, but in reverse. And for that matter, WHY is a positive trail length more stable/desirable for high speed riding?

  8. Seeing that bike keep itself upright by itself with just this novel computer-controlled steering axis gimmick makes me think of another application. Remember those fully enclosed motorcycles ( LIT Motors )? Instead of those little retractable training wheels it uses to balance at a stop, it could use this tech. Would have to switch from leading swing arm suspension in the front to forks.

  9. I want the bike to park istelf into tight spots so i don't have to squirm out of them after i place the bike and have to leave.

  10. Hi , thanks for the wonderful videos. I don't understand how the computer sense de the the status of the bike in order to make corrections. You say they are not using gyroscopes (I guess of any kind ). Are they using other kind of aceleradora, or some sensor of other kind ? (Optical or radar or otherwise)

  11. This just makes riding a motorcycle a bit more practical and easy in some situations. I see no reason why it should looked down upon, just very cool engineering

  12. Loosing balance and falling over while stopped is one of the most common motorcycle accidents. Oily spots next to intersections get really slippery when it just starts to rain.

  13. you had explained very good I am following your channel for 2 years…
    I had one suggestion whatever you write use another people to write else writer clearly

    thank you so much for clearing my basics of automotive concept.

  14. Wtf? Who wants this? Put this in scooters for girls, that's where it belongs.

    Make something that makes the bike faster and more fun. Stop wasting time on nonsense.

  15. dunno. i em not an experienced rider, howeveri found heavy bikes more suitable.
    witch sounds bollocks, but it does help me a lot, i weight less, far less than my bike so whenever i corner, the bike "leads" my tilt so to say. all i have to do is basicly grip the tank with my legs and just sortha move along with the bike and things are really efforthless.
    on a small bike i had issues with slow speed manuvers. with thisone i can go at really really slow speeds without problems, and even manuver verry percisely.

  16. Imagine you can just take a walk with your bike 😀 who needs dogs, motorcycles are the best friend of the human now

  17. im short and have to jump off and stand beside it when i come to a stop light, id love to have this so i didn't have to stand beside it each time.

  18. No man, the bike will go to the same side, on both cases. when you turn the wheel, it's center goes always to the side you turn, so the bike always will pent to the other side. the only diference on the inclinate position of the turn point do, is to have more or less effect on that.

  19. Yeah, a bike that stands up on its own. what kind of loser needs a computer to keep their bike standing up on its own.

  20. Nerds will buy it. It's complicated. Nerds like complicated stuff that turns simple when you study it. Until something breaks. Anyhow, very interesting show.

  21. Wow! I'm blown away. If they produce it at a good price point, it will sell like hot cakes. My question though, when the wheel is turning all over the place then you go to take off,what keeps you from going side ways into another lane or causing you to fall over while taking off?

  22. im still kind of not clear on how the bike stays upright even with zero forward momentum… is it literally pushing itself upright with its front wheel?

  23. I think its cool in the sense of hopping off the bike for a second and just leaving it there but im still trying to find a situation it would be useful for me while actually riding.

    I guess if you are a first year waddler that cant go under 5mph without your feet down haha

    Cools stuff though

  24. Amazing, Honda keeps surprising us with their toys, made to make our life easier and safer on a bike! Hope to see this concept on our dealers.

  25. If I were old/disabled and wanted to ride, I’d just get a 3-wheel motorcycle. Also, having to put your feet down at a stoplight isn’t a problem big enough to want to buy an ultra expensive self-balancing bike. However, there is one big opportunity I see for this bike. And that’s shared transportation. In the future, Tesla wants to allow you to share your car with others while you’re not using it. Well, what if we could share motorcycles too? That’d be pretty sick!

  26. Great R&D for autonomous delivery bikes. Honda is thinking ahead, when humans will be banned from riding motorcycles.

  27. Honda engineers then you can use similar processes during high speed medium speed low speed Falls by keeping them motorcycle parallel to the road surface in most situations with a gyro

  28. Now that you've done one motorcycle video, I'd be interested to see more. Nobody is doing scientific evaluations of motorcycles. For instance, I'd love to see a video on the safety differences of different types of motorcycle, i.e. chopper, cruiser, sport bike, adventure bike, street bike, etc. All have different centers of gravity, riding positions and front fork angles and lengths. Which is optimal for maneuverability and safety?

  29. Kinda like learning to drive a stick shift by driving an automatic transmission…
    I'd rather develop skills rather than rely on engineering

  30. When he said that the bike will be controlled by a computer the first thing that came to my mind was Motor terminator lol.
