In the minds of many car owners, ABS can make the braking distance shorter and make the vehicle easier to control.
However, in the hearts of many old drivers, only their own feet are credible, so there is such a statement that "ABS is safer and better to use without braking.". And this argument is also very simple, since ABS this device can ensure your personal safety in an emergency and reduce the occurrence of accidents. But here's the problem! It's really so powerful, why are there still many vehicles that have runaway "drift" accidents during emergency braking?
Today, Tiger will come to talk to you about what the ABS system is? Is it better to brake, as the old driver said?
From aviation to the car
The British invented the Germans to carry forward
When it comes to ABS, we must first understand the reasons for its birth.
As early as World War II, French and German engineers had experimented with a variety of brake anti-skidding systems in the railway and aviation fields at that time, and in the 2050s, Dunlop, the first to use disc brakes, developed a brake system that could improve the braking efficiency of RAF aircraft by 30%.
In the 1960s, the Ferguson Institute first used it in F1 racing cars, until the installation of an electronic anti-lock braking system on the Anglo-French jointly developed Concorde aircraft, the British had reached the peak of this technical field, and the next baton was handed over to the Germans, who would be responsible for reducing the manufacturing cost of the ABS anti-lock braking system and becoming the standard for ordinary vehicles.
When Mercedes-Benz and Bosch announced the ABS braking system in August 1978, the brochure read: The brake system uses a computer to monitor the speed of the wheels during braking, and if the speed is suddenly reduced, such as when braking on a wet and slippery surface, the computer will automatically reduce the brake pressure, and when the wheels are re-rotated, the brakes will be pressurized again. The whole process is repeated several times over a few seconds of braking.
Some people may not agree with this idea, but at least the ABS brake system makes people understand what traction control is, so that car manufacturers can add different driving experience under traction control to the same model through different settings of the ABS brake system.
How does ABS work?
ABS means anti-lock braking system, that is, when braking, ABS can prevent brake locking, even when braking sharply, you can control the vehicle, reducing the possibility of accidents.
During the braking process of the vehicle, the ABS control unit continuously obtains the signal of the wheel speed from the wheel speed sensor and processes it to determine whether the wheel is about to be locked.
If it is judged that a wheel is about to lock, the ECU issues a command to the brake adjustment device to close the normally open input solenoid valve to cut off the channel between the brake cylinder and the brake wheel cylinder, so that the braking pressure no longer increases.
Because ABS allows the vehicle to maintain ideal grip on various adhesion roads during emergency braking, the vehicle becomes controllable during emergency braking, thus resolving dangerous situations. Moreover, the ABS system is the premise and foundation for high-level active security configurations such as ESP.
A lie that has deceived the owner for decades
ABS is really not as good as point brake??
There are many rumors about ABS, and even the driver's test papers are wrong and even contradictory.
The following Taige will make a collection of these abs wrong views that are taken for granted, and refute them one by one
1. AbS has a longer braking distance than point brake
The earliest tire deadlock system was applied to aircraft in 1929, and at that time, it was naturally impossible to have electronic sensors and ECUs to judge, but to use pure mechanical construction.
In the test, it was shown that the system shortened the braking distance by 30%, mainly because the pilot did not need to slowly increase the braking to find the maximum braking force, only need to brake at full strength, and this also reduced the tire puncture and other situations.
This is the German Bosch company to do in the wetland brake experiment, from top to bottom are the use of ABS brakes, point brakes, and slam brake braking distance, if you do not believe you will definitely say, this is Bosch in order to promote their own products to do a fake experiment. (Just be happy)
Countless experiments have proved that triggering ABS is more reliable than the so-called old driver braking, and the braking distance is shorter. ("Riders" who can follow the brakes please sit, you are not counting most people)
2, F1 and other racing cars, do not use ABS brakes, because of the increase in visibility
When Tiger first entered the car circle, he also agreed with this statement, for example, the braking distance controlled by ABS is not a completely effective brake, but the racing driver can completely achieve better braking than the computer. But the old masters who use their brains know that this is obviously nonsense
F1 racing cars generally have four wheels, a brake pedal (except for Tyrrell P34), that is to say, this one brake pedal controls the braking force of the four wheels in real time, and the braking force distribution is locked at each time the brakes are locked, F1 racing cars do not have EBD (braking force distribution is adjustable in real time), F1 in order to lock the rear wheel brakes when braking, the braking force must not be divided to the maximum, because at the beginning of the brake, the axle load moves forward, and the braking force of the rear axle load becomes too light and excessive, which will cause the rear wheel lock to be locked and thrown out of control.
In the 1993 season, the FIA announced the ban on all driver assistance devices: CVT and ABS, ESP, active suspension systems, which can greatly reduce the driving difficulty of the car and make the lap faster. Obviously, the team will not disable such a strong auxiliary system to "add trouble" to itself.
3. ABS uses part of the braking performance in exchange for steering when braking, so the ABS braking distance has not become shorter
It's even more ridiculous, like you said that eating burger fried chicken will make you fat, and hamburger fried chicken has no nutrition.
While braking retains a certain steering ability, which is a by-product of ABS brakes, there is a certain steering force when the tire is not locked and rolling, which is not in conflict.
4, ABS on the ice surface, snow braking distance becomes longer
On deep snowy roads and gravel roads, as well as ice surfaces, locking brakes can indeed achieve the shortest braking distance, but at the same time it will be accompanied by the loss of control of the vehicle, tail flicking, overturning, and rotation, and ABS brake distance on these special roads without the need to make the vehicle out of control The braking distance is almost the same.
If you still have questions, ask yourself why governments around the world are making it mandatory to install ABS
Will it still be installed if it is not useful?
