The lock-up phenomenon generated during the braking process is that when the car brakes are stepped on, the car will give the wheel a force to stop it, so that the wheel cannot continue to rotate, but the wheel has a certain inertia, after the wheel has stopped rotating. , it will continue to slide forward for a certain distance, and finally stop completely. The so-called locking phenomenon of car brakes is that when the car brakes are stepped on, if the front wheels and rear wheels of the car are not in the same straight line, because of their inertia, the front and rear wheels will slide toward their respective fronts, which makes When the front and rear wheels run in two different directions, the car will drift. In this case, the steering wheel of the car has no effect, and the car will lose control completely. If the situation is very serious, it is very likely that the car will overturn. Therefore, in the braking system of the automobile, the performance and stability of the anti-lock braking system of the automobile are particularly important for the automobile.
