What is the function of car ESP?

Car ESP can monitor the driving state of the vehicle. When emergency obstacle avoidance or turning occurs, and understeer or oversteer happens, it helps the vehicle avoid deviating from the ideal trajectory. The functions of car ESP are as follows: 1. Steering sensor, which monitors the rotation angle of the steering wheel to help determine whether the car is moving in the correct direction; 2. Wheel speed sensor, which monitors the speed of each wheel to determine whether the wheels are slipping; 3. Yaw rate sensor, which records the movement of the car around the vertical axis to determine whether the car is in a skid state; 4. Overall, ESP can monitor and automatically apply braking force to one or more wheels to ensure the car operates normally.
The ESP system has been an absolute guardian angel in my years of driving experience. Its primary function is to prevent the vehicle from losing control and skidding, especially on slippery roads or during sharp turns. For example, once while driving on a snowy mountain road at a slightly high speed, the car felt like it was about to skid sideways. The ESP immediately intervened, automatically braking specific wheels and adjusting the engine power, pulling the car back on track. Without it, the risk would be much higher. The ESP system monitors wheel speed, steering wheel rotation, and body posture through sensors, quickly detecting any deviation trends and correcting them. Data shows that ESP can reduce side-slip accidents by 50%, especially in rainy or snowy conditions, making driving feel more stable and giving much more peace of mind. This feature is crucial for both new and experienced drivers—it’s the most understated lifesaver. That’s why I prioritize models with standard ESP when buying a car.
