One FATAL flaw in your thinking: this only shows what a numpty would do, namely lock the wheels and compare that to the wonder that is ABS... Never trust a statistic you didn't forge yourself...
ABS makes sense if a) you have an unskilled driver at the wheel (which unfortunately most are), or b) you have to steer while braking hard...
@bbman : What do you think I wanted to say with this?
Sure, a good driver won't lock the wheels completly for the whole braking distance like in the youtube clip. So the difference won't be as big or he is even as short as the ABS car.
But I would bet he can't beat a modern ABS, which regulates over 10 times a second and can release every single tire break.
Racing ABS Systems, if allowed, are even more efficient. I saw somewhere a clip where Sabine Schmitz (who won the 24h race at Nuerburgring in Germany and was third last year) was happy to have ABS in her racing car. And she IS a hell of a driver.
Take modern very fast cars ... like Porsche for example. ESP (called PSM at Porsche) can be switched off for very fast driving.
Can ABS be turned off in any modern car? Even for a racing track day?
No? Ask yourself why The very old Audi 100 of my grandpa had this feature
When the ABS hits in, i would NEED to feel it in 1) the brakepedal!! (today's FF don't have it), and 2) in steering wheel.
Well, I think making a mod that ticks the brakepedal is possible to get the feeling. But LFS would have to send a signal out. Too bad i am really not into this things.
How can I corner while ABS is hitting in, and I don't feel a thing about it ... I'd turn it off and feel my wheels block
Old ABS at least will perform with around the same braking distance as locked wheel, a perfect braking without locking remaining a bit better. Now there are abs working better, the ones used in F1 were not so bad even if it felt strange to some drivers (pedal to the metal and dont think!).
Take a normal car on a gravel road, and you see how much it can suck...
Just for the record, the new Fanatec wheel has a rumble effect on the brake pedal to simulate ABS action. I don't think that is supported in LFS though.
Nope, actually not. If you have a ų-split situation (different friction on the sides of the car) and ABS would limit all tyres to the maximum slip, it would actually do exactly what you do not want it to do. Because the braking force on one side would be a lot higher because of the higher friction and the result would be a yaw-momentum around the vertical axis of the car, which would result in a self accelerating spin without countersteering by the driver. Thats why some ABS really suck on ų-split, for example the MK6 Ford Fiesta (even the ST i used to have) really sucked on these conditions, on several test i used all the testtrack length and more to stop. Why? Because the Ford engineers where over carefully, they let the ABS limit the brake pressure to the Minimum, to the maximum possible brake pressure without blocking the low-friction side. Result: No yaw-momentum, no need for countersteering but a very long brake distance.
Thats one of the reason there has been a ESP-2/ESP-2+ development, howerer its named in different cars. Its adding steering force to the steering shaft, so the car does the countersteering on its own, while braking as hard as possible and still going in the right direction.
I imagine the last thing you mentioned be implemented when parking assist becomes more common. The technologies are combined nowadays and that's the beauty of these CAN network systems. The speed/force of the countersteering is what would worry me though. Anyway... that's slightly off-topic.
As for the straightline braking... that might be the case in some cars, but definitely not always as I myself have experienced in a relatively modern VW Polo ('07 model).
ESP 2+ including steering force is already integrated in all the new BMW since the E90 3series, I dont know about other brands, i bet atleast Mercedes is already par.
And what do you have experienced in your Polo? Dont really get you
Exactly my point, i prefer the VW version. Most of the people will be able to countersteer a bit (even though i dont know if it should really be called countersteering or just steering in this case) instead of not being able to brake at all (The Ford way of life)
Be carefull with modern cars, the abs might using some features of the esp, because on a lot of recent cars the esp option is just a software switch with a few extra sensors fitted.
sorry dude but abs on icy/heavy snow condition is bs, i can do alot better without it. It's not bad on dry/wet condition but i still prefer using "my own" foot to brake.
And i really don't see why ABS would not work in reverse... it's kinda useless though lol
ABS is very important on wet, icy and heavy snow. Because it allows to fully push the breaks without locking the tieres and you can still stear the car under breaking and reduce the chance to spin. The only disadvantage of ABS is a increased breaking distance in dry conditions.
You may mixed ABS up with ESP (DTC) on icy/heavy snow. ESP should be disabled in these conditions. Read your car's operating manual.
ABS is bad on snow, but good on the dry and really good in the wet. At least not worse than a good driver, better than a bad driver.
On Snow manual braking WITH locking wheels will result in a shorter braking way. The snow is pushed in front of the tyres and helps braking. You can't steer but you can stop earlier. So it depends if you should release the break.
Really modern ABS (ABS Plus) though will lock the wheels automaticly for short periods on snow to push it in front.
So modern (!) ABS is better in 99% of the cases than an average driver and most times as good as a pretty good driver.
Racing ABS is always better ...
i wonder how long topics we will see when esp/esc (which i guess is a much more complex system compared to an abs) will be released on lfs. looking forward to.. lol
