What is the abbreviation of ESP?

ESP stands for Electronic Stability Programme. It belongs to the active safety system of vehicles and can also be referred to as a dynamic driving control system. Based on the ABS (Anti-lock Braking System) and ASR (Traction Control System), ESP incorporates additional information from sensors such as the steering wheel angle sensor and lateral acceleration sensor. By controlling the wheel brakes and engine power, it corrects skidding. ESP working principle: During vehicle operation, the steering wheel angle sensor monitors the driver's turning direction and angle, the vehicle speed sensor monitors the speed and throttle opening, the brake master cylinder pressure sensor monitors the braking force, while the lateral acceleration sensor and yaw rate sensor monitor the vehicle's yaw and roll speed. The ECU processes this information to calculate the discrepancy between the vehicle's intended safe path and the driver's input. The ECU then issues commands to adjust the engine speed and braking force on the wheels. If there is a deviation between the actual and desired trajectory, the ESP system automatically applies braking to specific wheels to correct oversteer or understeer, preventing skidding, excessive steering, insufficient steering, or wheel lock-up, thereby ensuring driving safety. ESP functions: It ensures vehicle stability (laterally) during steering maneuvers, preventing side skidding. ESP can detect the driver's intentions and actual driving conditions at a frequency of 25 times per second. During steering, it can automatically and selectively brake individual wheels or control the engine and automatic transmission to maintain stable vehicle operation. ESP components: Sensors: steering wheel angle sensor (monitors steering angle), wheel speed sensors, yaw rate sensor (monitors rotation around the vertical axis), lateral acceleration sensor (monitors wheel lateral slip), brake pressure sensor, ECU, and actuators.
Last time I was driving on the highway in the rain, my car started to skid a bit, but thankfully the ESP system automatically intervened and got it under control. ESP stands for Electronic Stability Program, an electronic stability control system. It uses sensors to detect if the wheels are slipping and if the vehicle's direction is inconsistent, such as when cornering or on slippery roads. If it senses the car is about to lose control, it automatically brakes individual wheels or reduces engine power to help maintain stability. This thing is really useful—driving with it on icy winter roads significantly improves safety. I recommend checking the dashboard light to see if it's on before each drive, as some cars allow it to be manually turned off, but for safety, it's better to keep it on. New drivers should especially familiarize themselves with this feature.
