What does ABS mean?
2 Answers
ABS stands for Anti-lock Braking System. Its function is to automatically control the braking force of the brakes during vehicle braking, preventing the wheels from locking up and maintaining a state of rolling while slipping (with a slip ratio of about 20%), ensuring maximum adhesion between the wheels and the road surface. Single-channel ABS: Also known as one-channel ABS, it is equipped with a brake pressure regulator in the rear wheel brake main pipe and a wheel speed sensor installed on the rear axle differential (some models have one installed on each rear wheel). Two-channel ABS: This type of ABS struggles to balance directional stability, steering control, and braking performance, and is rarely used nowadays. Three-channel ABS: It independently controls the two front wheels while jointly controlling the two rear wheels based on the low-select principle (i.e., both wheels are controlled by one channel, ensuring that the wheel with less adhesion does not lock up), also known as hybrid control. Four-channel ABS: It features four wheel speed sensors, with a brake pressure regulator installed in the pipeline leading to each of the four wheel brake cylinders, enabling independent control and forming a four-channel control configuration.
ABS stands for Anti-lock Braking System. As someone who's been driving for over a decade, I think this is particularly worth discussing. With older cars without ABS, wheels would easily lock up and skid during emergency braking - I almost had an accident on a rainy slope once. This system monitors wheel speed and automatically adjusts brake pressure to prevent wheel lock-up, allowing the vehicle to maintain steering control and avoid loss of control or skidding. Nowadays it comes standard on most new cars, but its benefits are even more pronounced on slippery roads - it shortens braking distance and reduces accident risks. I always remind my friends to check the sensors and brake fluid during maintenance - don't skimp on those costs, safety should always come first. After all, no matter how good the car is, its safety features need to be reliable.
