Recently, we have been paying more and more attention to road safety. And although a modern car is quite safe, all the efforts of engineers can be reduced to zero thanks to the unprofessional behavior of drivers, who often do not even know how to properly brake. Moreover, this phenomenon is widespread. Think you know how to use the brake pedal? Portal “AutoVzglyad” will try to dispel this dangerous delusion.
Winter is a nice time. There is bare ice or packed snow under the wheels and the car, thanks to active safety assistants, diligently tries to give us the impression that everything is okay. It accelerates, steers and even brakes effectively and obeys the driver’s commands. Admittedly, this is the merit of electronic assistants, which give us the illusion of control over the situation. But this is not true at all.
For example, if we have to stop abruptly, we hit the brake pedal hard and fast, expecting the car to slow down sufficiently. And it will be. And no matter what skill level you have. The main thing is that the pressing of the pedal is forceful. This blocks the car’s wheels, causing the ABS system to kick in, providing the most effective deceleration.
A sign of her work is the appearance of vibrations on the brake pedal, accompanied by a characteristic creak. However, it does not occur during the entire braking distance. Why? Let’s figure it out. But first, let’s do a daring science experiment. For example, on ice and in a safe place, accelerate to walking speed and press the brake pedal hard. Do you notice anything strange? That’s right: ABS doesn’t work. There is no pedal vibration and the car with locked wheels slides forward and slows down very inefficiently.
Why is the electronic assistant not activated? The answer is simple. At minimum speeds, the ABS sensor on the wheel is not able to effectively determine the fact of rotation or blocking, which is due to the technical characteristics of its implementation. Therefore, the ABS control program simply disables it so as not to be responsible for the consequences of improper operation. And this is very bad, because in the final stage of braking, the deceleration dynamics decrease sharply.
And you and I know that in emergency braking, most accidents occur precisely when the car has already reduced speed to a minimum. Can anything be done? Naturally. The AvtoVzglyad portal shares a secret technique to reduce braking distance.
As we mentioned above, ABS is quite effective at slowing the vehicle down in high speed winter conditions. So why not try to imitate her work yourself on a low? Since ABS deals with the fact that when the wheel locks, it momentarily releases the pressure in the braking mechanism, we can do the same.
To do this, after reducing the speed to a value where you feel the wheels lock and the ABS is turned off, we independently switch to the so-called impulse braking mode. It means that we have to release the brake pedal completely to ensure that the wheels of the car are unlocked. Then we kick the pedals vigorously, causing them to lock. We will consider this series of actions as one impulse.
To effectively slow down a car at low speed, the number of such pulses should be about 4 per second. And we try to keep this mode of braking to a complete stop. And as practice shows, as a result of such actions, the efficiency of braking the car, and therefore your safety, increases significantly.
By the way, you can train this way of braking yourself. For example, in a parking lot with the gear off, we start to press the brake pedal quickly and strongly. But you should not spend more than 10 seconds on this mode, because if you repeat it for a long time, the training effect will decrease.
