What is the function of ESP in a car?

ESP stands for Electronic Stability Program. Here is a detailed introduction to the ESP system: 1. Function: ESP is the Electronic Stability Program, which analyzes vehicle driving state information from various sensors and issues commands to ABS, EBD, etc., helping the vehicle maintain dynamic balance. ESP can keep the vehicle stable under various conditions, with particularly noticeable effects in cases of oversteering or understeering. 2. Oversteering situation: When the ESP system sensors detect and transmit signals to the ESP control unit, it will intervene by braking the outer front wheel during steering. Through single-wheel braking, this allows the vehicle to remain stable without driver intervention. 3. Understeering situation: After the ESP control unit receives the sensor signals, it brakes the inner rear wheel during a turn. Through such braking corrections, the vehicle's stability is also ensured.
I've been driving for over a decade, and ESP is one of the features I trust the most. It's called Electronic Stability Program, and it quietly intervenes when the car shows signs of skidding or losing control, such as when turning on wet roads during rainy days. The system automatically senses wheel speed and steering angle, then quickly adjusts braking force or limits engine power to bring the car back on track. I've tested it during high-speed sharp turns—without ESP, the car might have drifted, but with it engaged, I clearly felt much safer. Before every trip, I always check to ensure all safety systems are functioning properly because ESP significantly reduces the risk of rollovers or collisions, especially for family outings, making everyone feel more secure. It has become a standard feature in modern cars, offering strong protection, and I recommend all drivers understand how it works.
