What does it mean when the car ESP light is on?

When the car ESP light is on, it indicates that the Electronic Stability Program is active. When the ESP is working, the ESP indicator light on the dashboard will illuminate, and it will turn off once the vehicle returns to normal driving conditions. The ESP system includes functions such as Electronic Brakeforce Distribution (EBD), Anti-lock Braking System (ABS), Traction Control System (TCS), and Vehicle Dynamic Control (VDC). The principle of ESP is: through the ABS electronic control unit, based on signals from the wheel speed sensors, the system calculates and analyzes the wheel slip rate and vehicle speed. The electronic control unit then adjusts the wheel slip rate by controlling the throttle opening and brake pressure.
