What is the role of the ABS system? The anti-lock braking system can improve the safety factor of emergency braking of the vehicle when driving. In other words, for a car without ABS, when the car takes emergency braking in an emergency, the tires are prone to lock up, that is, the steering wheel cannot be turned, so the risk factor will increase accordingly, and it is easy to cause serious consequences.
Single-channel ABS generally controls the two rear wheels together according to the principle of low selection. Single-channel ABS cannot make full use of the adhesion of the two rear wheels, so the braking distance is not necessarily shortened significantly. In addition, the front wheel braking is not controlled, and the front wheel will still have brake lock when braking, so the steering control ability has not been improved. However, since the two rear wheels will not lock during braking, the braking can be significantly improved. The directional stability is a major advantage in safety, and at the same time, it has the advantages of simple structure and low cost, so it is widely used in light trucks.
To sum up, although the ABS device can shorten the braking distance, in addition, the price of different types of ABS devices varies greatly due to the composition and structure, so when purchasing a car, you should not only see the price, but also the installation and use what type of ABS unit it is.
