Extended data

ESC mainly controls the longitudinal and lateral stability of the vehicle and ensures that the vehicle runs according to the driver's consciousness. The electronic stability control system is based on the anti-lock function of ABS braking. When braking, the tire is about to lock, and the system brakes hundreds of times a second, which is a bit like mechanical "point braking".

In this way, when the vehicle is fully braked, the tires can still roll, and the effect of rolling friction after locking is better than sliding friction, which can control the driving direction of the vehicle.
