Will the installation of an anti-lock braking system significantly reduce braking distance?
1 Answers
Installing an anti-lock braking system (ABS) can reduce braking distance. During vehicle braking, the system automatically controls the braking force to prevent wheel lock-up, maintaining a state of rolling and sliding (with a slip ratio around 20%), ensuring maximum adhesion between the wheels and the road surface. However, ABS systems have their limitations. In two scenarios, ABS may not provide the shortest braking distance: one is on smooth, dry roads when braking is performed by an experienced driver, and the other is on loose gravel, soft soil, or deep snow-covered surfaces. The anti-lock braking system enhances safety during emergency braking. Without ABS, emergency braking can easily lead to wheel lock-up, rendering the steering wheel unresponsive, thereby increasing the risk of severe consequences. Single-channel ABS typically controls both rear wheels based on the low-select principle. This type of ABS may not fully utilize the adhesion of both rear wheels, so the braking distance might not be noticeably reduced. Additionally, since the front wheels' braking is not controlled, they may still lock up during braking, leaving steering capability unimproved. However, single-channel ABS significantly enhances directional stability during braking by preventing lock-up of the rear wheels.
