What is the ESP switch?

ESP switch has the word 'off' on it, and the related explanations are as follows: 1. Introduction: ESP can maintain the best stability of the vehicle under various conditions, and the effect is more obvious in the case of oversteering or understeering. ESP is the electronic stability program of the vehicle body, which is a general term for systems or programs aimed at improving the handling performance of the vehicle and effectively preventing the vehicle from losing control when it reaches its dynamic limit. The electronic stability program can improve the safety and handling of the vehicle. 2. Supplementary explanation: EBD is to adjust the braking force distribution to prevent the rear wheels of the vehicle from locking first. It generally fails only when the module hardware fails; ABS is to prevent the wheels from locking. By calculating the vehicle slip rate, it is controlled near the peak adhesion coefficient, which belongs to passive safety control.
The ESP button in my car is located among the row of buttons on the left side of the steering wheel, with an icon showing a skidding car. One winter when climbing a snowy slope, the wheels spun out, and the system cut off the power. I pressed this switch to temporarily disable ESP, allowing the wheels to grip and climb up. However, you should never turn it off casually in normal situations—it can truly save lives at critical moments, like when the car body starts to skid during a fast turn on a rainy day, and the system pulls it back. Mechanic Lao Zhang said this function should generally remain on, except in special situations like being stuck or starting on a snowy slope, and it should be turned back on immediately after getting out of trouble.
