ABS - NATURAL CHOICE

Revise the appointment of ABS-it just prevents the locking wheels during braking. Too much brake pedal is pressed? Not misfortune-electronics, comparing the rotational speed sensor signals at each of the wheel determines the time of the wheel and sudden stops, opening electromagnetic valve, dumping excess pressure from the brake line to the special gidroakkumulyator. Brake pads razzhimayutsya, rotation of the wheels is restored, re-activates the valve highway to the pressures that with the help of the vacuum brake amplifier creates a right leg driver. And if this pressure is still too big, the cycle repeats itself over and over again. In the cabin inclusion ABS evident in the work of executive cod block and push on the brake pedal, more or less visible depending on the design of the system.
In fact, the ABS simulates actions experienced driver who escapes to the slippery road wheel, using discontinuous break. But ABS makes it inaccessible to humans frequency and accuracy up to 15 times per second. As a result, the ABS should not only provide a minimum of cars stopping distance, but also compel it to listen to the helm, because the wheels down and take the side effect, as far allows chaining tires coated. And this is the main advantage of ABS. Indeed, in the case of wheel machine neupravlyaemo slide directly, even when vyvernuta steering wheel to lock.

CONCERNS
It would seem that all it is already clear. Anti system avtomirom recognized by all civilized and have already become standard equipment on vehicles, starting with the middle class. But there are often dissatisfied and vote.
"No electronics not like the skilled driver, say some. Give me - the same car without ABS, and I will stop before!"
Another did not like the fact that ABS braking interfering in the process, exclude entirely right. Ironically Davi pedal, it will be unpleasant vibration vytalkivatsya back. The machine itself hampers, affect the course does not slow down, the same ABS is very difficult to calculate the stopping distance and predict where it will stop the car. One can only wait ... Dank for the driver accustomed to own situation!
A third stress on rallistov. Breakwater, ABS nedarom those afraid of the plague! A happened, athletes, photos ... In order to set everything on the ground, we have the technological crime. Got a plug under the hood, which comes to an executive block ABS, and dragged him from the nest, forcing fire yellow kontrolku ABS and alarmingly zamigat brakes, the red light in a combination of devices. So we deactivate anti neotklyuchaemuyu system.
The tests took place under the scheme. We chose four major exercises: braking on the direct-to a homogeneous and mixed surface (Mixte), in-turn, and while science institutions obstacles (ie when maneuvering perestavka). Passat equipped recording equipment accurately measuring the speed and stopping distance. However, some of the exercises was asked to commit ordinary drivers and various kinds of skills, from beginner to motorists experienced professional. Any chance to control before arrival, accustomed to a car and to adjust fire "to the next maneuver.

HOW TORMOZIT?

With all the anti-lock system is simple: you want to get the maximum possible deceleration - Topi, did not think there pedal to the floor. And as a stall without ABS?
. Initially, we tried to do everything "on the theory of" stall on the verge of locking wheels. Do not go! Too responsive folksvagenovskaya pedal may not accurately modulate braking force, and we are wrong, both in the one and the other. And this in a calm atmosphere.A poprobuyte-ka do so in extreme situations where an accident threatens!
Then we used a tested method-jerky braking.

For comparison tried not mudrstvuya excuse, stall "in the floor, with locking wheels. What is the difference? In direct contrast, in the main exchange rate stability. Especially so vividly demonstrated during braking on Mixte. Under the leftist wheels was wet asphalt, but under the right-curb snow cover.
Since included ABS machine first starts away towards cover with the best clutch, but electronics is working properly: Passat instantly aligned and brake in a straight forward, almost without requiring podrulivany. During intermittent ABS braking without the driver had little podrulivat, and the braking distance has more.
But with full wheel locking car was halted almost as efficiently as ABS. But while his razvorachivalo sharply left at a dangerous angle to 40 on!
Winnings ABS here is obvious.

Karpov COVERAGE
Ice is smooth as a mirror and shershavym as surface Emery. Snow is tight, raskatannym, loose, slipshimsya, smerzshimsya ...
Why is us? And the fact that each has its own specific coverage, and after our tests give clear answer to a question at all what conditions ABS braking distance will be less than without it, we can not!
Options for the masses.For example, when repeated stops on the same direct wheel of our car nakatali gauge raskroshennogo Ship shershavogo ice, the ABS braking distance and that it is not locked with the wheels facing almost the same. Nedarom our athletes are told that most "tenacious" is not the asphalt coating, and ispolosovanny "nails" ice track.
And in the snow, is the so-surprise!ABS-machine stayed a little later. Any case that the snow cover on the adhesion rate was lower than the rough ice-Ship is not working so well. Для АБС, видимо, это оказалось невыгодным. For ABS, apparently, it was unattractive. But when "normal" interrupted braking for the period wheel lock them, a snow roller, which helped to slow the car more intensively.Work same ABS prevents wheel lockup and-roller fails.

RUL BOYTES NOT SPIN!

Braking-turn in (ice)

Imagine it is the real situation: in front of you suddenly slippery-turn captures truck, and it turns across the road. Or another: a sideways neshirokuyu travel to the street directly in front of the nose and the machine slips peregorazhivaet your lane, leaving only free counterclaim. In the wake of rebirth in the blood of driver adrenaline panic, reflexly that there is a urine press the brake. Zablokiruyutsya Wheels. A locked wheels with the car in the first turn on the outside situation exits, and the second-vrezhetsya an obstacle. For without ABS will help avoid accidents only intermittent braking and the driver is required not only remarkable composure and extract, but remarkable skill. It is our example. Opytneyshemu experts needed to call on the assistance of all their ability to, strictly alternating graduated shocks on the brake pedal and precise work of the wheel, repeat and even surpass the results of just the same maneuvers with ABS.

But what of it? Even testers needed to do more than a dozen pristrelochnyh races, but in the real world the chance to be only one! And electronics here and works reliably good.
When braking in the turn of the driver's task was even the simplest: clicked on the brake, steering wheel, and turned the car, clearly a predetermined trajectory tracking are also slowing. It is available to any. It is important to just remember that during braking with ABS machine can and should be managed. Not otsepenelo compress the steering wheel, and they act boldly!

In science institutions obstacles (we delayed in the performance of our readers familiar maneuver perestavki), the situation was such. When the speed of maneuver close to the limit, after science institutions obstacles began to evolve skidding rear axle. This was as ABS, and without it. But using ABS has been able to pay speed so that the skidding was not as sharp and deep. And science institutions after stopping distance was 15 meters shorter. It is! True to stay on the road, when skidding correction had to release the braking pedal, even with running anti-lock system. Why? Do not argue, the ABS leaves room to change the trajectory of emergency braking, rather than skiing in a straight line with locked wheels. But with the fight against skidding ABS work too diminishes the effectiveness of corrective action driving. And even those drivers whose cars are equipped with ABS, in such situations need to be ready for a moment to release the brake pedal, consciously abandoning electronics services.

Braking at the unbalanced coverage (Mixte), the upper figure, and to direct (ice), the lower figure.
