What are the disadvantages of ABS anti-lock braking system?

Briefly introduce ABS first, and then talk about the shortcomings.

ABS, the abbreviation of anti-lock braking system, was first used in airplanes, then installed in limousines, and now it is basically popularized. When a car without ABS is braked in an emergency, the wheels are easy to lock, the front wheels are motionless, and the rear wheels are easy to shake. ABS can solve this problem well. The theoretical slip rate of the vehicle is calculated by computer, compared with the ideal state, and the decision to increase or decrease the brake pressure is made and adjusted. Therefore, ABS can keep the wheel braking in a slightly slipping rolling state all the time, without locking and avoiding danger.

ABS can only be compared among different kinds of ABS, regardless of the manufacturer's factors. Now ABS is divided into 4 channels, 3 channels, 2 channels, 1 channel.

Four channels means that each of the four wheels has a brake pressure adjusting device, which can make full use of the adhesion of each wheel when braking independently. However, if the adhesion between the left and right wheels of the car is too different, the braking force of the two wheels will be too different when braking, which will produce a lateral force effect, which will make the car body lean to the side with large braking force and affect the stability of the braking direction. For example, ABS may not work on icy or very wet roads.

3-channel independent control of the front wheel and the same control of the rear wheel can ensure the stability of the braking direction of the car, but it can not make full use of the adhesion of the rear wheel and has little impact.

Channels cannot effectively combine directional stability, steering control and braking effects, so they are rarely used.

1 The braking effect of the channel is not obvious, the front wheel locking can not be solved well, the steering control is not good, but the direction is stable and the cost is low.

ABS is now basically a necessary equipment for cars, and the effect is very obvious. Now EBD and other electronic functions are based on ABS, and the results are outstanding.

The disadvantage is that when you want to play with a car, you can't do a series of stunts with it smoothly.

A car with ABS system will be more expensive than a car without ABS.

Moreover, ABS is not omnipotent, it also has its limits. When you exceed its limit, no one can help you! ~
