What is ABS Anti-lock Braking System?
2 Answers
ABS Anti-lock Braking System is a system that, during braking, quickly determines the wheel lock-up state based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve on the wheel that is starting to lock up, keeping the braking force constant. If the wheel continues to lock up, it opens the normally closed output solenoid valve, causing the braking pressure on that wheel to rapidly decrease due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking up due to excessive braking force. The functions of ABS are: 1. Maximizing the effectiveness of the brakes, reducing braking time and distance; 2. Effectively preventing vehicle skidding and fishtailing during emergency braking, ensuring good driving stability; 3. Allowing steering during emergency braking, providing good steering control; 4. Avoiding intense friction between the tires and the ground, reducing tire wear.
I've driven several types of cars, and the difference between those with ABS and without ABS is quite significant. ABS stands for Anti-lock Braking System, which mainly prevents the wheels from completely locking up during emergency braking, allowing you to steer and maintain control. I remember one time when it was raining, I braked on a slippery road. Without ABS, the wheels would have locked up, causing the car to skid and lose control. But with ABS, I could feel the brake pedal pulsating as the system automatically adjusted the braking force to keep the wheels turning. This not only shortens the braking distance but also helps avoid accidents. Nowadays, most cars come equipped with ABS, especially beneficial for new drivers in emergency situations. It's advisable to regularly check if the indicator light is functioning properly to ensure the system doesn't fail and compromise safety.
