What is the ESP System?
2 Answers
esp system is a chassis braking technology developed on the basis of the Anti-lock Braking System (ABS). It mainly consists of a control unit, steering sensor, wheel speed sensor, sideslip sensor, lateral acceleration sensor, etc. The ESP system achieves automatic vehicle safety control, effectively improving the driving stability and safety of the vehicle under dynamic conditions such as braking, driving, and steering. By analyzing the vehicle driving state information transmitted from various sensors, the ESP system then sends correction commands to ABS, EBD, etc., to help the vehicle maintain dynamic balance, achieving automatic vehicle safety control.
After driving for so many years, I place the highest importance on the safety features in a car, and ESP is one of the most crucial among them. Simply put, it's like an invisible bodyguard that steps in immediately when the car starts to skid or lose control. Once, while taking a high-speed turn on a rainy day, I clearly felt the wheels drifting, but the ESP system instantly intervened, automatically applying slight braking to the outer wheels to slow down, and the car immediately stabilized its trajectory. The principle is that it uses the steering wheel angle sensor to determine the direction you intend to go, combines data from wheel speed sensors, yaw sensors, and more, and then uses a computer to analyze the car's actual movement in real time. If it detects that the car is about to oversteer or understeer, it will brake a specific tire to help correct the direction. Nowadays, almost all cars priced above 100,000 yuan come with this feature, making driving in rain or snow much more reassuring.
