(Summary description)ABS is the English abbreviation of anti-lock braking system for automobiles. It is developed on the basis of conventional braking devices. Its role is to automatically control the braking force of the wheels when the vehicle is braking so that the wheels are not locked. Dead, it is in a state of rolling and sliding (slip rate is about 20%) to ensure that the adhesion between the wheel and the ground is at the maximum, and the steering wheel still maintains a certain steering ability to avoid obstacles.

Information
  ABS is the English abbreviation of anti-lock braking system for automobiles. It is developed on the basis of conventional braking devices. Its role is to automatically control the braking force of the wheels when the vehicle is braking so that the wheels are not locked. Dead, it is in a state of rolling and sliding (slip rate is about 20%) to ensure that the adhesion between the wheel and the ground is at the maximum, and the steering wheel still maintains a certain steering ability to avoid obstacles.
  The speed of the wheel is transmitted to the electronic control unit, and the electronic control unit instructs the brake pressure regulator to act, and adjusts the braking force of the wheel brake. During emergency braking, once a wheel is found to be locked, the electronic control unit immediately instructs the pressure regulator to depressurize the wheel cylinder pump to restore the wheel to rotation. The working process of ABS is actually a cycle of locked-released-locked-released operation, which keeps the vehicle in an intermittent rolling state that is critically locked, which can effectively prevent the car from shifting and sideways during emergency braking. Avoid skids and tail flicks to prevent the car from getting out of control.
  The ABS system of a car has a self-diagnostic function. When a certain component in the system fails or a logical conflict occurs during the operation of the system, the electronic control unit records these failures and stores them in the form of a fault code . In the ECU, the ABS fault lamp is lit at the same time.
  There are many reasons for the ABS fault lamp to light up. Generally, you need to use a car fault diagnostic instrument to detect the car, read the fault code, and determine the fault location. Common causes include broken fuses, virtual connections or disconnections, dirty or damaged wheel speed sensors, damaged electronic control units, and damaged brake pressure regulators. It should be noted that sometimes the wheel speed sensor failure is detected, but it is not that the sensor is broken, but it is dirty, just clean it up, but the repair shop will replace it in order to make money. At this point, you need to have one more eye, let the repairman clean it up first. In addition, the system will occasionally have logic faults. Although the ABS fault lamp will be lit, there is no substantial component damage. It is better to clear the fault code.
  Automobile When the ABS system fails, the car will stop the ABS system to ensure braking safety. At this time, the car is not without braking, but has only conventional braking capabilities. During emergency braking, the wheels will be locked directly, the brake pedal will not feel bouncing, and the car cannot turn. In addition, other brake assistance systems on the car, such as the body electronic stability system (ESP), drive anti-skid system (TSC), electronic braking force distribution system (EBD ), etc., are all functions based on the ABS system. When the ABS system fails, they will also lose effect, the handling performance of the car will be greatly reduced, the control ability of the body will be sharply weakened, and the car may run out of control during emergency lane changes and emergency braking. Therefore, when the car's ABS system fails, the driver should drive the car cautiously, do not drive at high speeds, avoid emergency braking, drive more carefully on wet roads, and go t o the repair shop as soon as possible to avoid a greater failure.
