Understanding Anti-lock Braking System (ABS) !
Vložit
- čas přidán 30. 05. 2018
- Nowadays an anti lock braking system is used in almost all modern vehicles. This system prevents accidents like this, where you lose control of the steering as you apply the brakes. With ABS you will be able to steer the vehicle properly and it also reduces the braking distance. What is ABS? How is it able to prevent accidents due to the braking? We will explore these questions in this video.

Engineers who solve these problems are amazing.
Proud to be one of them.

Thank you!
Are you saying the issue is hard to fix
All engineers are awesome and underrated
I recently experienced the ABS system and I thought my brakes were messing up because the pedal was pulsating and pushing back, I now know that it was keeping me safe!
Yes youtube , this is exactly what i meant when i searched for abs.
Underrated 😂
Here's a good ab workout czcams.com/users/shortsroPCvEOUaNI?feature=share
😂
@Daniel Brockman more abs on my channel
ABS YOU ARE STRONG
0:00 Me high AF trying to act normally
Sorry for highjacking your comment.
But why the fuck would i know what a "slip ratio" is or a "coeffecient of friction" is if i dont even know how ABS works? What university professor is this guy teaching? And what university professor doesn't know what ABS is? How can people be so "unaware" of what they're doing? I just want to know what ABS is, such a simple system yet such complex physics concepts are applied to explain it? Videos like this are exactly why bourbaki exists and ends up having to write mathematics textbooks themsellves
@Srajan Agrawal It's called sarcasm and this wasn't taught at my HS Physics class. Hopefully you'll understand.
@Srajan Agrawal Same here. I guess the US high school science syllabus isn't as advanced.
@@privatemak8901 well I mean, the video says " understanding" not "introducing" ABS so... maybe it was made with physics students in mind...
@@MU5T1 not really sure how to respond to this. introducing abs is exactly what this video did, lol. if any physics student watched this video alone and managed to build a custom abs system, his brain would probably be preserved for research, since it could performs miracles.
just my opinion: if a physics student gets to the point of needing to develop an abs system, he would probably have completed highschool physics and a few years of college, and would not benefit from the explanation in this video.
I thought i knew this stuff, but you guys managed to provide a MUCH deeper understanding of ABS then i had imagined. Under 7 minutes!! Wow! Keep up the good work!
God dammit. At 3:20 the braking sounds sounded so real in my headphones that I thought they were coming from outside on the road.
I just popped out my window for the same reason...
Same! Lolz.
Same lol
same here😂😂
Same
Can I just say, this made my driving theory test so much easier, it helped me understand so many questions, and I don't know if I'd have passed without it, so thank you SO MUCH!
The theory doesn't ask you anything about how abs works so how did you conclude that?
@@elixier33 He definetly meant something else, not the actual driving theory, it would be a different world if driving licenses required you to be a mechanic, lol
0:37 she isn’t pressing the clutch she will stall the damn car 😂
Was wondering 😂😂😂
The absolute last of your worries
tch..women drivers
Hahaha
Puch break without clutch is much better
Awesome explanation and video! I learned in Physics before ABS became a standard item in most vehicles that rolling to a stop is better than locking your brakes to avoid skidding. That meant pumping your brakes about 60 times per second. Lucky there's ABS! Thank you very much Dr. Kyle and Sabine.
I imagine the foot technique required to press and partially release the break 60 times per second is quite hard to pull off.
@@hetsmiecht1029 YES, AT LEAST 60 HZ
I had been using ABS EBED since many years without knowing how it works on the road. Thanks for your video lesson. Hope to see you soon with another great video. Thank you.
This is the best video for ABS in whole CZcams. A personal view.
Thank you guys.
You can test this system really easy in winter with the shiny slick snow ice surface. Hit the brakes hard and you’ll hear the ABS pump go to work and the brake pedal will pulsate. It’s kinda fun to do in a safe area and this system really works I can’t believe cars were made without this system
In my country since long before abs was introduced we were asked to repeat pump the brake quickly for better grip, now I understand why
This is just an old advice which can be detrimental in any modern car or bike with or without ABS. ABS system will be turned off if brakes are pumped and in a non ABS car which uses hydraulic braking system or power brakes will lose any kind of braking ability. Because of the vacuum pressure inside the valves, both ABS and non ABS cars use hydraulic system while ABS just prevents wheels from locking up and give steering ability in an emergency situation. It's written in a car manual. This advice is still rolling around because people just don't understand how a modern Braking system works. And yes, ABS works in milliseconds which no human can match.
An old racing trick.
Since roads are designed so you can take a corner at the speed limit, people aren't trail braking into corners in their daily commutes.
But you can't possibly pump brakes fast enough to mimic ABS optimum grip profiles. Pumping the brakes (or as racers call it, Brake Feathering) used to be a way to retain steering while braking. Which is the entire purpose of ABS. Because as you learned, locking the wheels causes understeer.
An added benefit of feathering brakes is to create "weight transfer", which is when a car's motion is transfered to the front wheels under braking due to inertia. Grip is a function of the normal force applied to the gripping element. Weight over the tire, in simpler therms. Provided the wheels don't lock, this also increases the grip on the front tires. Racers use it to take turns at a higher speed as more grip means the car slips less thus can turn better.
You shouldn't pump ABS brakes though. Most ABS Systems will understand that as an override command so you'll have to keep doing it so the wheels won't lock up.
@@bokinoki If by *modern* you mean a vehicle that was made in recent years, then you're dead wrong.
My 100cc motorbike made in India in 2019 still works well with this technique. Go figure
Scare the shit out of me
Neel_kant I think you meant hydraulic/ air pressure based breaking systems.... cheaper vehicle like 2 wheelers still use cables to handle the breaks, they all have got Human ABS!.
As you mentioned, motor bikes that have hydraulic disk breaks, if they don’t have ABS, it becomes really tricky to hit the breaks.
In mountain bikes (cycle with fancy things), they call this feathering the breaks.
How about the fact that she’s driving with freaking high heels on?😂

How much time do you need to make one video? Appreciate your hard work
Exactly one month as of now :)
If anyone has doubts if this is reasonable, it totally is.
The quickest team by a big margin is South Park who make 20 minutes content in 6 days. But they have far more than 4 people and far more than 60 people if you were to extrapolate it to this video. And in the case of South Park all of the moving animations most often come from existing assets already and it's mostly still backgrounds that have to be added. Having to make all these new mechanical parts and making the animations for them is what takes so much time.
Learn Engineering Your all the videos are fabulous & very informative...... !!! Keep going !!! 👍👍
I wanted this information thanks
to nres
I kept on asking if the Friction is more in sliding why car would stop In less distance with ABS .
Really thanks for providing the answer . Really appreciate your good work
perfect sliding is actually almost always at a lower frictional coefficient than "beginning to slide". This applies even to a smooth block of brick.
No other There isn't any other such channel on CZcams which could explain any such certain topics in an eloquent manner like you guys Thanks guys .
I was driving today, and had to slam on my brakes to avoid a bicyclist that came in front of me. I felt my brakes slip. I knew my car had abs but didn’t know what it what or felt like. It concerned me. Thanks for teaching me something new.
Instead of going to your local auto mechanic with your concern you when home and watched youtube videos.
I did the same thing today. Did you have to repair anything? My abs brake system light is on, and taking it to the mechanic on Wednesday... trying to save money lol. I know your post is from 2 yrs ago, just giving this a shot..
@@annagarcia2456 they probably died because they thought they understood abs from this video
The part of explanation of negative acceleration is the best. Great video. Huge thanks from Armenia
The explanation of ABS is good. However, at 6:15 what is being referred to as EBD (Electronic Braking Distribution) is in fact not EBD. That is ESC (Electronic Stability Control) or a sub-function of ESC. EBD (actually Electronic Braketorque/Brakeforce Distrubution) distributes the brakeforce between front axle and rear axle. EBD does not counteract yawrate.
Thats the abilty of the transmitter and its distribution /release of pressure on individual reciever on each wheels...i forgot the instruments on each wheel ...on trailers air to open is applied to the diaphram of the brake drum the air is calibrated depending on the signal recieved by the transmitter
Dose ESC needs a different hardware or it's just a software changes in some parameters?
Same damn thing.
The author of the video is not an engineer I could tell easily
@@frackjohn different hardware as it requires varying the brake force without any intervention from the driver.
This video really helped me because automobile engineering is a subject in my school and some of the things our teacher taught were unclear, but after watching this video, I understood it a lot better. Also, my exams are coming soon and this video helped me to recall my memory. So wish me luck!
Actually the description is not 100% correct. This animation discripes 3 different systems as ABS. The ABS is just stopping the brakes from blocking not more ! The description for braking on a road with different surfaces or driving around a street barrier and holding the car in lane it's called ESC (Electronic Stability Control) or DSC. Also description how it works is not really correct. To hold the car in the lane on different surfaces the DSC (Drive Stability Control) is braking not blocking just one wheel at a time to hold the car in place. Also this system helps you to go around a barrier or any obstacle in your lane in a higher speed the system usually starts acting on a speed around 50km/h and prevents you car from slipping. This system (DSC) should be turned off by driving in deep snow. Because the DSC works together with the TCS (Traction Control System). The TCS prevents the wheels from continuous turning what makes you stuck in the snow. So next time you drive in deep snow find the button on your dashboard (or center console) with a DSC (or ESC, ESP) on it and push it A orange light will come on what says the car can slip now. This is ok for the moment because if you let the DSC on and drive in deep snow on the next hill you hit the gas pedal and the TCS will feel the wheels losing traction so it will bring down the motor tours and the wheels turning slower this will make you stuck in the snow!

The ABS actually increases the braking distance compared to braking perfectly with ABS off. However, it is very difficult to achieve and requires practise, not to mention the fact that ABS makes it easier to steer properly while braking. In the end I think ABS is a fair tradeoff between braking distance and steering capability.
Yep, proper threshold braking is a skill you need to train, while anyone can stomp on the brake pedal.
There was definitely a big difference between some of the domestic manufacturers and Bosch ABS systems, my Audi A4 was much much better in the snow breaking, it seemingly new when to increase the brake pressure to make up for lost distance when ABS was triggered.
You know that rolling wheel actually have more friction than a skidding wheel IF YOU HAD clear YOUR 11 CLASS PHYSICS BACKLOGS.
Therefore, reducing braking distance.
Not true. No matter how good you are at braking, under certain conditions, there will be times that one wheel may need more braking than another to most effectively reduce the car's speed. No matter how good you are at braking, you cannot choose which wheel is receiving X amount of brake pressure. So there are times where no matter what, ABS (assuming it's a solid system) will be superior to even the most trained drivers.
I would disagree, under most practical road conditions, ABS would decrease the braking distance during panic braking.. Only under hypothetical ideal conditions on paper would ABS increase the braking distance.. Dude, when u slip and slip badly, there is such a bad braking distance, which is enough to decide between life and death..
Thank you very much. WHen I was a university student there were no such learning aids. This would have helped me a lot.
You should be awarded for making a brilliant conceptual video on this topic. Teachers like you are the diamond which is not available every where. Thanks

Dude he is wrong that’s not the real reasons 😂
The explanation is just wow!!!! It amazes me how such concept is easily explained in this video,.. salute to you guys..
I have a Honda 2012 accord and we just got hit with a heavy snow storm up in New Hampshire recently. She's a good car, and did her job when I decided to go driving the next day. Upon exiting my drive way, the ABS system kicked in, as I was turning on some slippery slush, as it should. Unfortunately, the system never turned off and has been stuck in the 'On' position since then. I took out my manual and learned how to turn it off. I have a family member who works in the automotive industry and thinks I either might have low tire fluid or a glitch in my abs system. I'll be checking it out soon, but this is a nice video seeing how it works.
Absolutely amazing.
Yes. This technology saved my life last year...... When due to fog I was just about to meet an accident.....
Great video! I learned something new today. I learned it vaguely from my dad who is a mechanic what ABS does. This in-depth explanation clears a lot on the physics of this system. The level of engineering done on this is pretty amazing. Now I know what that box near the brake fluid chamber does :)
This is a straight up fantastic explanation!
Genius way of teaching. Should start doing fundamentals.

Very informative and educated, im always have many question for the ABS glad that been answer and i now understand how it work🙏 Thank you
“You still dont understand do you?”
“That eight six has human abs”
"After all, ABS can't outperform the right foot of a highly experienced driver like him"
"You can't figure out how to properly use ABS until you've mastered braking without it. That's the Toudou school's rule."

As a man I would never dream of wearing high heels when driving!🤣

In simple terms, ABS prevents the wheels from locking up so you don't skid.
Very simple and easy to understand! Keep on doing this type of video again😁👍
nice video, thanks for the information👍
ABS is a technological marvel, It has reminded me of my old friend from high school where his first car was a 1998 Chevrolet Cavalier with a faulty ABS system. He ended up smashing a telephone pole because the roads were incredibly icy at the time and was going too fast. Lack of ABS played a big role in when he wrote that car off
Check of u have ? If me

Driving in high heels isnt that bad, the smooth soles can slip on the pedals tho.
Wonderful, thank you!
After several years my jeep's ABS system is finally back to normal
Basically, how much force the wheel and surface can add to the car defines how fast the car stops.
When a wheel its not slipping, it's able to deliver more force than when it is slipping.
And thus the solution of slapping computational power into the problem reveals itself. Great series, BTW.
Great video, I've got answers to all of my questions!

Tdrr
Actually, I would explain one part of the video differently (sorry for my imperfect English in advance). Static friction on same contacting surfaces is much higher then sliding friction, that is why, for example, its harder to start sliding sofa then keep it sliding when pushing, it feels like its sticked to the floor. Here, when wheels are rolling, they have static friction with ground, ABS, as explained in the video, prevents wheels from locking and by this, it allows us to keep maximum friction with the ground to reduce braking distance. Great video overall ^^
Yeah he said friction during pure rolling is 0 which is not true, there can't be any rolling without friction.
Brilliantly Explained !!
ABS has a big flaw. Usually the intermittent action is mostly noted when raining and helps, however there have been times when I’ve been at normal speed in dry conditions and the car in front suddenly stopped, so I hit the brakes abruptly to the floor by instinct. ABS has caused the car to travel much more than what it would have if I had hit the brakes without the instinct of doing it abruptly, as I have made the test of being at the same speed and hitting the brakes normally. I always say I hate the ABS due to this fact but this video has helped me see this flaw is one of the many instances where ABS acts and more times than not it helps. I wish this issue could be looked at, perhaps releasing brake at a different or variable frequency
If you floor the brakes then i am glad you had abs with you.
If a car in front of you brakes suddenly and you floor the brakes probably you will hit them without abs in a dry/wet/any condition. Especially in manual drive.
So please dont disable abs for testing or for real.
@@YanYan-zu8dc Hi. I didn’t disable them, just did the same speed (which wasn’t that fast, about 45 mph), but braking not so fast and it stopped quicker without sliding because it didn’t trigger the ABS system. The problem is, you can’t control instinct as to not floor it in an emergency. I believe ABS serve its purpose when it’s raining or there’s a puddle, but in dry conditions ABS is good only if you’re at high speed
@@thelastofyou i dont think you understand what happens when the wheels lock up, especially the front ones. ABS is a safety device. A locked wheel provides no steering, zero. If your front wheels lock up you can go sideways very very fast. If your abs hadnt been there you would have gone straight to the curb or into oncoming traffic.
Disable your abs and go to an empty parking lot and slam your brakes. It will surprise you how fast your vehicle takes off to the side when the wheels lock up.
Proper braking technique always stops you faster. Abs only activates when you use improper braking technique and it prevents you from losing control of the vehicle.
