What does ESP mean in cars?

ESP stands for Electronic Stability Program. Below is a detailed introduction to the importance of ESP: 1. Research by the Insurance Institute for Highway Safety (IIHS) in North America shows that installing ESP can effectively reduce fatal traffic accidents by 43%. 2. Studies conducted by the National Highway Traffic Safety Administration (NHTSA) in the United States also indicate that making ESP a standard feature can effectively reduce single-vehicle accidents for sedans by 34%, rollover accidents for sedans by 71%, and even reduce single-vehicle accidents for SUVs by 59%. 2. ESP is primarily used to address the risk of tailspin loss of control caused by continuous steering during emergency obstacle avoidance. When emergency evasive maneuvers are performed, ESP intervenes to increase the driving force of the drive wheels; when a tailspin tendency occurs, ESP applies braking to the opposite wheel to reduce rotation, thereby helping the vehicle follow the driver's steering intentions.
I've been driving for over a decade and have encountered ESP quite a few times. The Electronic Stability Program sounds fancy, but it's essentially a computer-controlled technology that manages all four wheels for you. When you take a turn too fast or make a sudden steering maneuver, it detects if the car starts to skid or veer off course. At that moment, it automatically applies brakes to specific wheels or slightly reduces engine power to help pull the car back on track. That time on the highway when I had to swerve to avoid an animal that suddenly darted out, if it weren't for ESP immediately intervening to control the direction, I would have almost hit the guardrail. Now I feel especially confident driving on mountain roads in the rain, knowing there's an extra layer of protection.
I remember driving back to my hometown last winter and feeling particularly nervous when encountering icy sections of the road. At one point, the car suddenly slid slightly sideways, and the steering wheel adjusted itself a few times lightly. Later, I found out that this was the ESP (Electronic Stability Program) in action. This system continuously monitors the angle of the steering wheel and the actual direction of the car's movement. Once it detects a mismatch between the two, indicating that the car is about to lose control, it immediately adjusts power distribution or applies braking to individual wheels to stabilize the vehicle. Once, my friend's new car accelerated too hard on a curve, and we clearly felt the system intervene to pull the car back on track. For everyday driving, it’s most needed on slippery roads to ensure safety.
