What is the function of ESP?

The function of ESP is to automatically intervene and correct the driving when the driver operates the car beyond the limit. The ESP function is enabled by default and is controlled by the vehicle's computer throughout the process, requiring no driver operation. The methods by which the computer controls the vehicle's movement include: 1. Controlling the throttle to reduce fuel intake, thereby diminishing the car's power and slowing it down; 2. Applying brakes to certain wheels to reduce the car's speed to within the limit. Generally, vehicles equipped with ESP will have an ESP OFF button, which is used to turn the ESP function on or off. Some models do not have this button.
As a seasoned driver with years of experience, I often encounter dangerous skidding situations in rainy or snowy weather, where the ESP (Electronic Stability Program) becomes my lifesaver. It continuously monitors the vehicle's operating conditions, including speed, steering angle, and tire slip rates. Once it detects any tendency of the vehicle losing control—such as sliding out of a curve or skidding during emergency avoidance—the system immediately activates braking on specific wheels or appropriately reduces engine power to help stabilize the car. This gives me much more peace of mind when driving on highways, especially on slippery roads after rain, as ESP significantly reduces the risk of accidents. When buying a car, my top choice is always a model equipped with ESP. Although it may cost a bit more, it’s absolutely worth it—safety is priceless. I also make sure to maintain the tires and the system regularly to prevent malfunctions. Since its widespread adoption in the early 2000s, ESP has saved countless drivers' lives, particularly in adverse road conditions. It works like an invisible guardian, silently enhancing overall safety and keeping us away from those terrifying moments of losing control.
