Is the Vehicle Stability System Effective?

The vehicle stability system is highly effective. Here are the specific functions of the vehicle stability system: 1. Maintains stability during braking: When the tires are about to lock during braking, the ESP (Electronic Stability Program) performs a "mechanical point brake" within one second, allowing the vehicle to maintain steering control even under full braking. 2. Maintains power output during slippage: When the drive wheels slip, the engine speed decreases to reduce power output, while the ESP's electronic control unit applies braking to the slipping drive wheels to prevent slippage and ensure appropriate power output. 3. Maintains output during evasive maneuvers: During emergency avoidance, the ESP intervenes by increasing braking force on the left side when turning left to enhance steering, and similarly on the right side when turning right. 4. Maintains stability during fishtailing: When the vehicle shows signs of fishtailing, the ESP applies braking to the opposite wheels to reduce rotation, helping the vehicle follow the driver's intended steering direction.

We often discuss this in our young car owners' group - ESP is truly a lifesaver. Once when I was driving on a mountain road and suddenly encountered a heavy rainstorm, I clearly felt the tires skidding while taking a sharp turn, with the steering wheel feeling like it was about to slip from my hands. Just as my heart rate spiked, the yellow car icon with skid marks flashed on the dashboard, accompanied by a stuttering vibration under my feet - that was the system braking individual skidding wheels! The car stabilized instantly. Now when buying used cars, we specifically check for this feature, especially for friends who frequently take long trips. Last time, my colleague's old Japanese car didn't have this function and spun 90 degrees on a roundabout during snowfall - fortunately there were no other cars around at that time.

Having worked in automotive media for over a decade, I've tested the ESP systems of hundreds of vehicles. At its core, this system is an upgraded version of ABS and traction control, utilizing 25 data points including steering wheel sensors and wheel speed sensors to assess vehicle posture 100 times per second. The most ingenious feature is intelligent torque distribution – for instance, when understeering during a left turn, it subtly reduces power to the right front wheel. I recall a manufacturer's test track comparison: in identical wet moose tests, a car with ESP disabled started fishtailing at 60km/h, but with ESP enabled could reach 75km/h. Nowadays, some electric vehicles have upgraded to e-ESP systems, benefiting from faster motor response.

Having driven for over seven years, I've found ESP particularly helpful for female drivers. Last month while taking my child to school, the car in front suddenly braked hard. When I swerved sharply to change lanes, I distinctly felt the outer wheels spinning, but the car body only swayed slightly. Later, upon reading the manual, I learned that the system not only braked the slipping wheels but also reduced engine output. I'd advise my fellow female drivers not to focus solely on reversing cameras when choosing a car - such active safety features are more crucial. Like my dad's old Passat without this function - it spun out on an icy bridge last year and hit the guardrail, costing nearly twenty thousand in repairs.
