Equipped with: ABS.
ABS: Anti-lock Brake System, as the name implies, is "anti-lock Brake System". Everyone knows that the maximum braking effect occurs in the moment before the tire locks up. If the braking force can always be kept in balance with the tire friction, the maximum braking effect will be obtained. When the braking force is greater than the friction of the tire, it will cause the tire to lock. Once the tire locks, the friction between the tire and the ground will change from "static friction" to "dynamic friction", which will not only significantly reduce the friction force, but also lose the steering track ability. Because the tire lock is the brake braking force and the friction between the tire and the ground, that is to say, the car between the tire lock limit will be with the characteristics of the tire itself, the condition of the road, positioning Angle, tire pressure, the characteristics of the suspension system and "at any time". ABS uses the speed sensor installed on the four wheels to judge whether the tire is locked or not, eliminates the uncertainty of human senses, accurately controls and timely releases the hydraulic pressure of the brake sub-pump, so as to prevent the brake from locking. At present, most ABS adopts the design of 12~60 times of continuous stepping per second (12~60Hz). Compared with the top professional racing drivers' 3~6 times, it is already a super high level of performance. The higher the stepping frequency, the closer the braking force can be maintained at the edge of the limit. The accuracy and reliability that ABS can achieve is beyond the limit of human beings, so we say: ABS is the most excellent quality and reasonable price equipment when buying a car. This is especially true in relation to the dangers of the Air-bag.
