Three situations in which ABS seems evil to you


Anti-Lock Braking System or ABS is a very cool, useful invention.

But many do not understand its functionality, which is why there are a lot of screams on the forums that ABS is evil.

That’s right, nothing at all and I don’t get tired of repeating it.

Why is it so important?

Having sharply pressed the brake all the way at high speed, the car will skid. It will begin to turn around, as the wheels blocked by the brakes simply slide along the surface by inertia, not reacting to the steering wheel. Braking is effective, but uncontrollable.

What does ABS do?

At the moment when the wheel is blocked, this system reduces the pressure in the brake system, preventing the wheels from blocking.

Everything is very simple: the system presses and releases the brakes with great frequency so that they do not break into a slip. Thanks to this, controllability is maintained and the car brakes smoothly. The driver, even with emergency braking, has the opportunity to go around the obstacle.

It is logical that if the brakes are pressed and then released, the car will slow down worse. Worse, but better.

That is, here lies the main feature of ABS: this system does not improve braking. It just keeps you in control.

In everyday life, this feature is invisible. On a good road with good tires, we get a comfortable emergency deceleration with an almost imperceptible increase in braking distance.

But not always. There are situations in which you may regret that your car is equipped with ABS:

On wet roads, we get significantly worse grip on the road surface. When braking, the wheels begin to lock up very early, the ABS starts to release them early, and the next time it works, again early locks play against us. It turns out that more time you brake without brakes, which is why you get a significantly increased stopping distance.

Here the situation is even more interesting: we get a very early blocking of the wheels due to the fact that the wheel in the pit is simply hung out and instantly blocks without traction. ABS releases the brake, immediately tries to catch it again, but again, the suspended wheel is blocked.

I had such a situation in reality: at a speed of under 80 km / h, I flew into a very bad section of the road. Ahead of me, a penny began to urgently slow down. And my ABS made it so that I, according to the feeling, actually did not brake at all. Only by a miracle did I leave the stern of the VAZ, taxiing to the right of it.

We read what is in the first paragraph, only by wet road we mean slippery. Again, insufficient grip and early wheel lockup.

And in the end we get: that ABS, which always increases the braking distance, on a bad or slippery road increases it by critical values. And you should always remember this and not count on the fact that a car stuffed with electronics will save you in any situation.
