What is the function of the car's ESP?
2 Answers
The function of the car's ESP is to improve the vehicle's handling performance while effectively preventing loss of control when the car reaches its dynamic limits. When the car experiences understeer, the body tends to push outward in the curve. At this time, the ESP system will apply braking to the left rear wheel to prevent the vehicle from getting into danger. When the car experiences oversteer, the ESP system corrects the dangerous driving condition by braking the right front wheel. The ESP can monitor the car's driving status in real time and, when necessary, automatically apply braking force to one or more wheels to keep the car running in the normal lane. In some cases, it can perform braking up to 150 times per second. It can also actively regulate the engine speed and adjust the driving force and braking force of each wheel to correct the car's oversteer and understeer.
As a veteran driver with twenty years of experience, I firmly believe that ESP can be a lifesaver! Its full name is Electronic Stability Program. You might not notice it during normal driving, but during sharp turns or on slippery rainy roads, it kicks in immediately. Using sensors to detect the car's tilt, it automatically applies brakes to individual wheels to pull the car back on track. I once experienced a close call during heavy rain while overtaking—I turned the wheel too sharply and nearly slid out of the lane. Thankfully, ESP intervened and stabilized the car, preventing a rollover. Its core function is to prevent loss of control, working alongside ABS, but ESP is more intelligent, correcting the car before it starts to skid. Remember, this feature is especially useful on highways or mountain roads, significantly reducing accident rates.
