For independent control of the two front wheels, the main consideration is small cars, especially front-wheel drive cars. The braking force of the front wheels accounts for a large proportion of the total braking of the car (up to about 70%), which can make full use of the two front wheels. Adhesion of the front wheel. However, due to the unbalanced braking force of the two front wheels, the influence on the stability of the vehicle’s driving direction is relatively small, and the resulting influence can be corrected by the driver’s steering control. Therefore, three-channel ABS is widely used in small cars.
Two-channel type Two-channel ABS is difficult to take into account in all aspects of directional stability, steering controllability and braking efficiency, and is rarely used at present.
One-channel one-channel ABS is often called single-channel ABS. It is to install a brake pressure regulator in the rear wheel brake manifold, and install a wheel speed sensor on the rear axle main reducer (also install one on each of the rear wheels).
