What does the ABS anti-lock braking system mean?
3 Answers
The ABS anti-lock braking system automatically controls the braking force during vehicle braking to prevent wheel lock-up, keeping the wheels in a state of rolling and sliding (with a slip rate of around 20%). This ensures that the adhesion between the wheels and the road surface is maximized. The anti-lock braking system can improve the safety factor of emergency braking while driving. Single-channel ABS generally controls both rear wheels together based on the low-select principle. Single-channel ABS cannot fully utilize the adhesion of both rear wheels, so the braking distance may not necessarily be significantly reduced. Without ABS, when emergency braking is applied in critical situations, the tires are prone to lock up, meaning the steering wheel cannot be turned, thereby increasing the risk factor.
ABS stands for Anti-lock Braking System, which is particularly useful in daily driving. I remember when I first started driving and encountered an emergency brake, the wheels suddenly locked up, causing the steering wheel to lock and the car to become completely uncontrollable. Later, when driving a car equipped with ABS, this problem disappeared. The system monitors the speed of each wheel and automatically applies braking pulses at a frequency of over ten times per second when you brake hard, keeping the tires in a state of rolling and sliding. This not only prevents skidding and side slipping but also shortens the braking distance. Once, on a rainy day on the highway, I encountered a sudden stop from the car in front, and it was the ABS that allowed me to stop safely. Nowadays, almost all cars come with this feature, and maintenance is simple—just make sure the wheel speed sensors aren't clogged with mud.
Anti-lock Braking System is the English abbreviation for ABS, with its core function being to prevent wheels from completely locking up during hard braking. I've seen too many accident cases involving older cars without ABS during repairs - locked wheels slide like sleds. Modern vehicles install speed sensors on all four wheels, with the ECU rapidly adjusting braking force through hydraulic mechanisms. The most direct benefit is maintaining steering capability during emergencies, allowing drivers to steer around obstacles. Moreover, it can reduce stopping distances by 10% on dry roads, with even more noticeable effects on slippery surfaces. However, note that the brake pedal may pulsate when ABS activates - this is normal and you shouldn't release pressure. In winter, regularly check if sensors are covered by ice or snow.
