What is the function 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 adopts emergency braking in an emergency, the tires are prone to lockup, that is, the steering wheel cannot be turned, and the risk factor will increase accordingly, which can easily 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 may not be significantly shortened. In addition, the front wheel brakes are not controlled, and the front wheels will still be locked when braking, so the steering ability has not been improved, but because the two rear wheels will not be locked when braking, the braking force can be significantly improved. The directional stability is a big advantage in terms of safety, and at the same time, the structure is simple and the cost is low, so it is widely used in light trucks. To sum up, although the ABS device has the function of shortening the braking distance, in addition, the prices of different types of ABS devices vary greatly due to reasons such as composition and structure, so when purchasing a car, you should not only look at the price, but also the installation What type of ABS device is it.
