How to operate ABS anti-lock braking in rainy and snowy weather in winter

ABS of automobile refers to "anti-lock braking system", which is called ABS for short. When the vehicle is running, if it brakes suddenly, it is easy to make the braking resistance exceed.

With the resistance between the tire and the ground, the wheels will lock up, making the vehicle lose its steering ability, even sideslip and tail flick, which is more obvious on ice, snow or slippery roads. ABS detects whether the wheel speed matches the vehicle speed when braking.

Judge whether the tire is locked, and control the braking force on this basis, so as to maximize the adhesion between the wheel and the ground and improve the handling performance during braking. As a novice, how to use it correctly?

Function of ABS

Simply put, the function of ABS is to prevent the vehicle tires from locking up during emergency braking, and to avoid losing direction and wheel skidding during emergency braking. The anti-skid performance of vehicles equipped with ABS on dry asphalt pavement, rainy day and snowy day is much higher than that of vehicles without ABS.

In recent years, as automobile consumers pay more and more attention to safety, ABS is listed as standard in most cars. If there is no ABS, emergency braking will generally lead to tire locking. At this time, rolling friction becomes sliding friction.

The braking force is greatly reduced. Moreover, the front wheel is locked, and the vehicle will lose its steering ability; If the rear wheel is locked first, the vehicle will easily slide sideways, making the driving direction uncontrollable.

ABS misunderstanding

first

First, correctly understand ABS. Some media put forward the theory that ABS can greatly shorten the braking distance, which is inevitably exaggerated, and sometimes ABS may even run on uneven roads and roads with gravel or snow.

Therefore, the braking distance is longer than that of vehicles without ABS. So, don't be too casual when driving a car equipped with ABS. It is very dangerous to follow the car too close, turn sharply or force the line to merge.

Secondly, ABS system doesn't work every time it brakes. It only works when the wheel is close to locking. It should be noted that the brake pedal does not work quietly. If ABS works while stepping on the brake pedal, it will produce appropriate noise, and the brake pedal will repeatedly pulse and arch. Don't worry, this is a normal phenomenon that the system automatically adjusts the brake oil pressure.

Secondly, some old drivers who are used to driving cars without ABS are used to stepping on the brake pedal back and forth during emergency braking to improve the braking effect. This operation method has been automatically realized in cars with ABS. So this kind of

The control method is not only redundant, but also hinders the normal work of ABS system and greatly reduces its performance. Therefore, it is correct to always step on the brake pedal with your foot when braking.

After that, the failure rate of ABS system is relatively low. Generally speaking, if ABS fails, it will automatically remind the driver in the form of lighting the ABS failure warning light on the dashboard. If the light suddenly comes on, it's not the time.

In a panic, drive the car smoothly to a regular 4S shop for maintenance. If the ABS and handbrake lights are on at the same time, it means that there may be a serious problem in the braking system of the vehicle, and you should slow down and wait for rescue immediately.
