What do ABM and ABS mean?

1, ABM (Asynchronous Balanced Mode), which is translated into asynchronous balanced mode in Chinese and classified into IP and multimedia, is a data communication mode using high-level data link control (HDLC). Asynchronous means that there is no common clock for data transmission between two stations, and balanced means peer-to-peer communication between the two stations, which eliminates the "imbalance" between the master station and the slave station at both ends of the data link.

2.ABS is abbreviated as ABS. The function is to automatically control the braking force of the brake when the car brakes, so that the wheels are not locked and are in a rolling state (the slip rate is about 20%), so as to ensure the maximum adhesion between the wheels and the ground.

Advantages of ABS

When the wheel is about to reach the next dead point, the pressure of the brake oil makes the airbag move repeatedly, so that it can move 60~ 120 times in one second, which is equivalent to continuous braking and relaxation, which is similar to mechanical "point braking".

Therefore, ABS anti-lock braking system can avoid the out-of-control direction and wheel sideslip during emergency braking, so that the wheels will not lock up during braking and the tires will not rub against the ground at one point, thus increasing the friction force, making the braking efficiency reach over 90%, reducing the braking consumption, and doubling the service life of the brake drum, brake disc and tire. The anti-skid performance of vehicles equipped with ABS on dry asphalt pavement, rainy day and snowy day reaches 80%-90%, 10%-30% and 15%-20% respectively.
