What role does the ESP system play?

ESP's function is to automatically intervene and correct driving when the driver operates the vehicle beyond its limits. The ESP system consists of a control unit, steering sensor (monitoring the steering angle of the steering wheel), wheel sensor (monitoring the speed rotation of each wheel), skid sensor (monitoring the vehicle's rotation around the vertical axis), lateral acceleration sensor (monitoring the centrifugal force during turns), and other components. There are two methods by which the computer controls vehicle movement: 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 vehicle's speed within safe limits.
I've been driving for over a decade, and the ESP system can truly be a lifesaver in critical moments. I remember one rainy night on the highway when my car suddenly started skidding during a sharp turn. I panicked, but the ESP immediately intervened, automatically braking individual wheels to help stabilize the direction and prevent an accident. Simply put, ESP stands for Electronic Stability Program. It uses sensors to monitor wheel speed and body angle. When it detects that the car is about to skid or roll over, it quickly adjusts braking force and engine power to correct the vehicle's posture. This is especially useful on slippery roads or during emergency maneuvers, preventing loss of control. Without this system, a single skid could lead to a rollover or collision with a wall. It also works in conjunction with other features like ABS braking and traction control to enhance overall safety. Nowadays, ESP comes standard in new cars, and I always advise friends to pay attention to this feature when buying a car—it's worth the extra money, as safety is priceless. Don't neglect regular maintenance; dirty sensors could affect its performance.
