ESP is so important, why do you need the whole "switch"? Indeed, ESP is commonly known as automotive electronic stability program, the importance of automotive safety has gradually been well known, ESP is a collection of a number of active and passive safety functions of the car, including ABS (anti-lock braking system), ASR (drive anti-skid system) and VDC (vehicle dynamic control) three main functions, and other small functions such as HBA (hydraulic braking power assist), HHC (hill assist), TPM (tire pressure monitoring) and other functions.
To know why an ESP switch is set, we must first understand what the main function of ESP is.
ABS anti-lock braking system, is a function that everyone is more familiar with, that is, to prevent brake locking, reduce the possibility of vehicle loss of control when braking sharply; ASR (drive anti-skid system) simply put, that is, when the vehicle is out of control, the vehicle state is controlled, mainly through braking and reducing the engine torque, to help the vehicle stabilize as soon as possible; VDC (vehicle dynamic control), simply put, it is necessary to control the direction of the vehicle when the vehicle slides and tails, Generates a pendulum torque opposite to the direction of deflection of the original vehicle, allowing the vehicle to remain stable.
The function of ESP, in most cases of our daily driving, is not perceived, but if you find a closed road brake, you can immediately detect the intervention of the anti-lock braking system. ESP is like a silent guardian, only in an emergency, it will appear to pull you.
However, the MONITORING OF THE STATE OF THE ESP SYSTEM IS JUDGED BY WHETHER THE TIRES HAVE SLIPPED, AND SOMETIMES THERE WILL BE MISJUDATION, OR ADVERSELY AFFECT THE DRIVING SAFETY. For example, the following situations:
1. When the vehicle needs to get out of trouble. Many people who play off-road should have experienced, the vehicle is stuck in snow, sand, how can not drive out, at this time you need to turn off ESP, because ESP perceives that the vehicle is slipping, will think that the vehicle is out of control, is to limit the engine torque, close esp is conducive to the vehicle out of trouble.
2. When driving in deep snow. Be careful, only when the snow is deep, it is suitable to turn off ESP, and if the snow or snow starts to melt, remember not to turn off esp! This is because the deep snow will make the vehicle often skid, but there is no melting deep snow to make the vehicle slip, it is easy to let the vehicle get stuck in the snow, at this time you can turn off the ESP slowly.
3. When the vehicle is driving on the track. ESP as an electronic stability program, each manufacturer's calibration is different, some factory trademarks are very conservative, such as some models of Volkswagen. If you run the track, the high-speed cornering situation, obviously the vehicle has not yet reached the limit, but the ESP will forcibly intervene and vigorously correct your direction and speed, but it will cause danger, so if you run the track, depending on the calibration of the ESP, you can turn off the ESP.
4. When measuring zero hundred acceleration. Many evaluation agencies, when testing the zero hundred acceleration of a vehicle, will often turn off the ESP, because sometimes they need to catapult to start, if the ESP is open, after detecting skidding, it will limit the engine power, and it will not be able to detect the best zero hundred acceleration of a car.
How does ESP close? In fact, most car owners do not know how to turn off ESP, press the SWITCH of ESP, turn off not all the functions of ESP.
1. Press the ESP OFF switch, and the ASR function of ESP is turned off;
2. Long press the ESP OFF switch for more than 3 seconds, and the ASR and VDC functions of ESP are turned off at the same time;
3. Press the ESP OFF switch again and the ASR and VDC functions turn back on.
Some models do not have ESP switch, turn off ESP to take a special method, Volkswagen models are first turned off, the key to the power state (the engine is not started) after opening the double flash, continuously and quickly press the accelerator several times until the ESP indicator light on the closed state after stepping on the brake ignition.
Daily driving, do not turn off ESP, because it is closely related to your driving safety, but you can collect this article, if you hope that you encounter the above situations, you can turn off ESP as appropriate, you can go out happily, go home safely.
