You are a born communicator! It isn't easy for grandmothers like myself to learn about these concepts but you make them totally understandable, thanks!😊
It's going to try and correct your rotation, so the tire that can do that will apply the brakes. If you're oversteering a right hand corner (wheels kick out to the left) the front left tire will brake initially, then if the car slides out too much the left rear tire will brake to control the moment.
@PixelBanger Not entirely sure, though I would assume it would use an accelerometer (or multiple) to feel the forces on the car. Once the tires are pointed one direction but there isn't an opposing force (via the tires) and no acceleration is felt, the car could assume it was sliding.
@marcusthedog Well, a lot of sources. The most help came from researching Ford's AdvanceTrac stability control system, they did a good job of explaining it. As for most of my material it either comes from online or reading of automotive engineering books.
It will start with left front, go to left rear if it needs to; the goal is to not let the car rotate enough to need to, since you'd be fairly sideways at that point.
Not saying that at all. The system operates when your vehicle is on, period. But you can't simply swerve to the left lane, then swerve to the right lane at 80 mph and expect everything to be fine.
Tbh 1st impression before i fully watch ur video, seems like it might be just an average guy trying to do explanation about something, but turns your explanation is very easy to understand with ur simple example.. perfect for ppl like me who just started to really understand the tech in vehicles. Thanks for your video, gonna subs to ur channel 👍🏻🙏🏻
Porsche SUV’s have a feature that prevents rollovers by locking the brakes on the front outside wheel in emergency maneuvers. The wheel remains locked to the degree necessary to reduce rollover risk by measuring steering angle speed and vehicle speed. Their small SUV(macan) got results that confused the people doing the “moose test” on another channel. How does locking the brakes up prevent a rollover?
sometimes the hybrid Lsd with hand in hand with abs works to help us control the car when it goes to slippery or rough road because my car is not equipe wt this ESP. the car still go straigt not going to U turn or getting out of the road but will feel a little bit drifting.i think the max traction was work at rear wheel to give the car more power. i dont know but this is my experience a few week ago. The best way to safety drive is slow down when driving on bad road condition. really thankful to god because im not involved in accident.
Hey dude, I do like your videos, I actually hadn't seen any in a while and I remembered now, as I was asking myself how is my ESP operating in a given situation. Basically I drive more violently, swerve and shake the car a lot, and I have stability engage many times a day, so I am used to it, and even feel which tire it attacks in a given situation. What you say is true, but I feel that most modern stability programs may attack more than 1 tire at a time. If you shake violently or slide rough, my car applies it at several points in a second or less. Maybe you are showing one tire so the example is simple where you put the pin/lock of the car, so it tends to rotate the direction you want it too,
@imthaman1234 I drive a 99' Integra, stock, no vtec. I have a video on FWD and RWD, just search my channel. Eventually I'll get around to AWD. Need to find a Subie in a junkyard when I've got free time.
Because someone once told that one of his friends had traction control and he was driving behind him during a snow storm and he saw the brake light being activated while the car was being stabilized. Back then, I didnt know brakes were involved, so I was kind of skeptical, but even now, I wonder why the brake light would be activated since the car entire car isnt really slowing down but rather just being stabilized.
👀Look how far you've come from this video lol .. I love wen I try to explain something to somebody I can always just go to one of your videos and you can explain it a 100% better and that they can understand it
That means that stability control will operate not only in order to prevent sliding, but it will also help to stabilize the car when it's already sliding.
Stability control makes an over or under steering vehicle into a neutral steering one at the expense of speed (since power is reduced and brakes are applied), a neutral steering vehicle can still skid into the ditch, it will just skid into the ditch with all 4 wheels equally losing traction.
How will stability control operate while going sideways? I tried that once intentionally on a very slippery road - going slowly left turn and suddenly pushed hardly acceleration pedal (AWD car) - stability control reacted instantly, nevertheless rear of the car flinged out, so I had to counter steer and for a few seconds I was going sideways, stability control light was flashing during whole slide - which wheel was breaking while counter-steering?
4 years alter, but if I may answer this question on his behalf, some people may see the video asking how it works now. From experience I have done this thousand times, in FWD car and AWD Subaru's. Basically f you shake the car to the point where the tail kicks out for example to the left, the left front tire will react as a pin to help rotate the car to its straight position. Like the author of the video said, also the left rear tire will kick in. Now I think what you are asking is, what happens if you counter-steer to help the situation, as if there was no Stability Control on the vehicle, correct. I have done it many times, most situations still the same activated to break with ABS effect by the Stability- left front, left rear. What dies the counter-steer do then, if applied properly it additionally helps the situation- my own experience though.
Well you can always try to get a job, and see what you end up getting, you're not forced to take any offers, so at least apply. And if you don't find anything you like, you could just continue your studies. Personally I was ready to get out after 4 years.
wow your awesome people pay money for this thanks for free knowledge, subscribed. just curious what kind of car do you drive and you should make a video on RWD AWD FWD and mid engine
Can traction control and stability control work all at once? It seems like it could be applied in your example on the right side the white board in a situation where is was raining with a small friction coefficient.
on the second case how the Stability Control knows that at the second turn it isnt a regular turn to the right? If it did, it would brake the front right tire instead...
I see some videos on UA-cam where Ferraris, Lamborghini, mustang losing control especially when they accelerates fast. I saw a video Lamborghini was making a fast turn on intersection and he loses control and crashes, why they lose control?
Great videos, subscribed! I understand how the car can determine the intended path (by driver inputs), but how does the car "know" the actual path it is on in order to make the proper adjustments? Is it monitoring the forces from the road through the tires?
hii yr videos are totally great and really helping me to prepare for my exams bt i hv a bit out of track question.. i will be graduating with my bachelors degree in ME nxt year so should i go overseas to pursue my masters degree in automobile and thn do a job or should i look for a job just after my graduation?? which will be a better prospect... just asking yr suggestion. cheers..
why in the over steering example the car does not apply break to the left back tire? if the car over steering too much and apply break to the left front tire. the car will start to spin.and it is unsafe. so why left front?
hi dude it sounds like tarction control nly. is this a sophisticated version of traction control......can you please make the difference between the two?
as for the braking part. they already make those. only they're e-brakes, pushing the hydraulic ebrake forward brakes the left rear tire and pulling the ebrake would brake the right rear tire (or vice versa) it's made for drifting because if you brake the inside tire, it'll kick the rear end out SUPER easily. as for the reverse thing, that's literally impossible and i'd recommend watching his video on transmissions and you'll see why, and honestly, i don't see a benefit of doing this
The question here is "How would a car knows when it is sliding?", Is there some sensor. gyro of some kind? I think an explanation on this should be included in this video; 'just saying! Overall, NICE!
So I guess the computer knows the intended path from the steering angle but how the hell does it know the actual path? Is there like a gyro in the car (like in a cellphone) or what?
he is basically saying this: " a car that has four brake petals instead of one. instead of one break petal controlling all four wheels, the driver could manually stop each wheel with the break petal. he then states that it would be cool if the tires could go in reverse while the other tires are going forward or breaking, basically meaning all tires are free to do whatever they want, which probably wouldnt happen lol
what if there was a car withe 4 brake petals that contorled each wheel. it would be hard to drive but a cool challenge. it would also be cool if you could have some wheels in revirse while others a braking and moving forward. this would be a car u would have to drive on an airforce base haha
That's because it's a race car with plates and blinkers. Anyone can crash, but remember that just because you have the money doesn't mean you should get into such a fast and sensitive car.
You are a born communicator! It isn't easy for grandmothers like myself to learn about these concepts but you make them totally understandable, thanks!😊
He's good isn't he :))
Essentially, it doesn't really steer the car but it alters the dynamics making it steer more neutrally, allowing a safe turn.
best explanation in youtube in 2019. less than under 3 minutes.
Good question. I believe that brake lights are connected to the actual brake pedal, so they only turn on if the pedal is pushed.
@Diemorder I'll be graduating with my BSME in two months. :)
@IronPump89 Both; when braking it doesn't make too much difference.
It's going to try and correct your rotation, so the tire that can do that will apply the brakes. If you're oversteering a right hand corner (wheels kick out to the left) the front left tire will brake initially, then if the car slides out too much the left rear tire will brake to control the moment.

Likely from a system of accelerometers, as well as using the direction of the tire to see if the two match up.
@marcusthedog Well, a lot of sources. The most help came from researching Ford's AdvanceTrac stability control system, they did a good job of explaining it. As for most of my material it either comes from online or reading of automotive engineering books.
Yep!
It will start with left front, go to left rear if it needs to; the goal is to not let the car rotate enough to need to, since you'd be fairly sideways at that point.
I subscribed just because of how clear your explanations are even without Animations. the best engineering explanations i've seen.
I didn't really learn this stuff from college courses, check out my faqs for some answers regarding this. You can find the link on my "about" tab.
im a sistemology student of engineering, but i love your videos explaining how cars work, good job dude!, I drive a smart
The actual G.O.A.T when it comes to explaining concepts
Your end word of advice on using it for safety situations rather than speeding situations is great advice to have added to this video! Awesome!
Really helpful video. Definitions for understeer & oversteer better than many text books.
i was looking for this simple explanation for a long time. thanks!
Not saying that at all. The system operates when your vehicle is on, period. But you can't simply swerve to the left lane, then swerve to the right lane at 80 mph and expect everything to be fine.
Excellent!

It will attempt to, yes.
Not sure, maybe some models flash a light just as a safety measure.
Brief, and clear explanation, bravo!

GREAT EXPLANATION OF STABILITY CONTROL
Your videos are addictive man, keep it up :)

Best Channel on UA-cam :)
So, are you saying stability control only works up to a certain speed. If so, what is this max speed?
Good job explaining this stuff.
I'd love to see a vid on motorcycle safety controls
Very well explained

Great job bro
Very good talk
Take that Red Bull! Haha thank you!
Intended path -> Streering wheel
Actual path -> Inertial sensors (per example)
How much do the Stability Control systems differ between the various manufacturers?
on the second case how the Stability Control knows that at the second turn it isnt a regular turn to the right? If it did, it would brake the front right tire instead...
I see some videos on UA-cam where Ferraris, Lamborghini, mustang losing control especially when they accelerates fast. I saw a video Lamborghini was making a fast turn on intersection and he loses control and crashes, why they lose control?
the pilot disable the tractions control.
you mean all those super cars losing control turned their traction control off??
Jack Bauer the stability and traction control can altered by mechanics, tuners or the driver itself if they know how to alter it.
Great videos, subscribed!
I understand how the car can determine the intended path (by driver inputs), but how does the car "know" the actual path it is on in order to make the proper adjustments? Is it monitoring the forces from the road through the tires?
Sure, watch my video on traction control. Just search my channel. :)
hii yr videos are totally great and really helping me to prepare for my exams bt i hv a bit out of track question..
i will be graduating with my bachelors degree in ME nxt year so should i go overseas to pursue my masters degree in automobile and thn do a job or should i look for a job just after my graduation?? which will be a better prospect...
just asking yr suggestion.
cheers..
hey thanx for yr suggestion i will look forward to it.
please explain us: how the link satabilizer works? does it matter?
why in the over steering example the car does not apply break to the left back tire? if the car over steering too much and apply break to the left front tire. the car will start to spin.and it is unsafe. so why left front?
hi! as always this vidwo too is highly informative.
i have a question.
does this ESP system available only on automatic transmission??
No, it is available on most modern cars, and basically almost every car produced nowadays, which means manual also.
You make my life so much easier taking Grade 11 Transportation Technology!
I am gonna try to replicate this in the game stormworks. This is gonna be fun, I can just tell.
hi dude it sounds like tarction control nly. is this a sophisticated version of traction control......can you please make the difference between the two?
Almost killed me one rainy day. Now I know why.
Well explained!
very well done.
When the computer makes the car brake in a certain wheel, does the brake light come up?
Awesome video is awesome!
What can you tell me about stability control on in wet conditions vs off assuming you can magically turn off it .
as for the braking part. they already make those. only they're e-brakes, pushing the hydraulic ebrake forward brakes the left rear tire and pulling the ebrake would brake the right rear tire (or vice versa) it's made for drifting because if you brake the inside tire, it'll kick the rear end out SUPER easily. as for the reverse thing, that's literally impossible and i'd recommend watching his video on transmissions and you'll see why, and honestly, i don't see a benefit of doing this
Hi! Nice vids , i am watching them all.
Whats the difference between ESP and ESC?
Michele Debenedittis Just marketing terms for stability control.
ESC closes the application.
iam dheeraj parmar from indian iam automobile engineer student thanks sir your video very good
Is it possible for a system like this to be designed to perform tight u-turns, intentionally, without a slippery surface?
Oh man found this oldie ✌️
What if the COG was to the other side of the front wheel? Wouldn't it just make the problem worse?
how about to discuss a u-split situation?
The question here is "How would a car knows when it is sliding?", Is there some sensor. gyro of some kind? I think an explanation on this should be included in this video; 'just saying! Overall, NICE!
How different is vehicle stability control from electronic stability control?
They're all the same system, just going by different names.
can you make a video about how to brake when to brake? have a car with out esp and van with abs and suv with esc.
Assuming no slip?
FINALLY THANK YOU!
Thankyou man
How does the car monitor its actual path?
So I guess the computer knows the intended path from the steering angle but how the hell does it know the actual path? Is there like a gyro in the car (like in a cellphone) or what?
sogerc1 yes, several in some cases.
Totally lost...
When he was explaining the under steer, isn't that differentials job?
Great, but can i add ESC to my car?
he is basically saying this: " a car that has four brake petals instead of one. instead of one break petal controlling all four wheels, the driver could manually stop each wheel with the break petal. he then states that it would be cool if the tires could go in reverse while the other tires are going forward or breaking, basically meaning all tires are free to do whatever they want, which probably wouldnt happen lol
it has only saved my life once
other times it has almost ended it lmao
goo work
how does the ecu know that the car is not travelling in the intended direction
Oldy but a goody
What would happen if there was a collision and the car says it has stability control damage
GREAT
cool mate
what if there was a car withe 4 brake petals that contorled each wheel. it would be hard to drive but a cool challenge. it would also be cool if you could have some wheels in revirse while others a braking and moving forward. this would be a car u would have to drive on an airforce base haha
GM's StabiliTrak kicks A! It is why I can drive a 650hp car, yet my insurance cost is pocketchange.
goated video
remember folks: A porsche carrera GT does NOT have stability control and that is what killed Paul Walker!
That's because it's a race car with plates and blinkers. Anyone can crash, but remember that just because you have the money doesn't mean you should get into such a fast and sensitive car.
It has very high lateral g at legal speeds it doesn't need stability control.... At (LEGAL) speeds.
It has very high lateral g at legal speeds it doesn't need stability control.... At (LEGAL) speeds.
YIC
Paul Walker wasn't even driving... moron.
well then your comment is wrong, no disrespect.
Stability control and traction control are the enemy to a drift in a RWD vehicle.
