Do you want to turn on ESP in snowy days?

It is estimated that many friends have noticed that among many buttons on the dashboard of a car, there is an icon of a car dragging its small tail. When you lower your head, you will see a sign on the center console that says "? ESP？ Close "switch.

The so-called EPS is the "body electronic stability system".

By correcting understeer and oversteer, the vehicle can run stably, while ESP? Close is the close button. Since EPS can ensure the stable driving of the vehicle, why design this close button? Wouldn't it be better to leave it on?

Some old drivers said that ESP should be turned off in snowy days, which puzzled many drivers. Should ESP be turned off when driving in snowy weather?

In fact, the key to improving safety when driving on snowy roads is to activate ESP, because the adhesion on snowy roads will be reduced. If the control force is too strong, the vehicle will have obvious tail flick or side slip, and ESP will try to correct these problems and prevent the vehicle from getting out of control to the greatest extent.

ESP is an important line of defense to ensure driving safety. Don't close it easily on dry roads or snowy roads.

Of course, in some special cases, it is necessary to turn off ESP.

When the vehicle is stuck in mud or sand

Imagine that the car is driving in the mud and the wheel adhesion is very small, and ESP will start to brake some wheels. ?

At this time, the engine torque will be consumed by the wheels with less rolling resistance, and ESP will limit the engine speed. Even if you step on the accelerator hard, it is difficult to escape, and you need to turn off ESP to get the vehicle out of trouble.

When climbing a mountain and slipping in rainy and snowy days,

When the vehicle is driving in snow or water, especially on the uphill road, the wheels are easy to slip. At this point, the computer will recognize the wheel slip, and the ESP system will limit the output of the engine. The result is a slope that ordinary cars can climb, because the start of ESP may not be able to climb.

When installing a snow chain on a vehicle

The detection signals of cars equipped with snow chains, such as wheel speed sensors and lateral acceleration sensors, will be inaccurate, which will affect the normal work of ESP system. ESP may continue to intervene or report fault codes, so it is best to turn it off.

When the car drifts,

When drifting, the wheels are in a slipping state for a long time. If ESP is turned on, it will interfere with and limit the slip of the vehicle, so it is impossible to make a perfect drift. Turn off ESP for a more perfect drift.

Every car with ESP system is turned on by default after parking. Different brands of cars turn off EPS in different ways. Some are short press "ESP? Close "button, have a plenty of long press" ESP? Close "button.
