What are the characteristics of ABS?

ABS characteristics: It not only has the braking function of an ordinary braking system but also prevents wheel lock-up, allowing the car to steer while braking, ensuring the stability of the car's braking direction, and preventing side slipping and deviation. It is currently the most advanced and effective braking device in automobiles. The role of ABS: It maximizes the effectiveness of the brakes, reducing braking time and distance. It effectively prevents vehicle side slipping and fishtailing during emergency braking, ensuring good driving stability. It allows steering during emergency braking, providing excellent steering control. It avoids severe friction between the tires and the ground, reducing tire wear. How ABS works: During braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that is starting to lock up, and keeps the braking force constant. If the wheel continues to lock up, the normally closed output solenoid valve is opened, 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. This keeps the braking state at the optimal point (slip ratio S of 20%), achieving the best braking effect and the highest driving safety.
ABS is truly a great driving aid with many notable features. Firstly, it prevents wheel lock-up during emergency braking, allowing you to maintain steering control—a critical advantage when avoiding accidents. I remember once encountering a sudden obstacle on a rainy highway; I slammed the brakes, but ABS kept the wheels rolling instead of locking up, enabling me to smoothly steer around it and avoid a rear-end collision. Another key feature is its real-time monitoring of wheel speed and road conditions via sensors, which rapidly adjusts braking force, significantly reducing the risk of losing vehicle control. On wet or icy roads, it stabilizes stopping distances, proving safer and more reliable than traditional braking systems. However, it's important to note that ABS is an assistive tool, not a cure-all—safe driving habits remain paramount. I recommend regular system checks to ensure sensor functionality and prolong its lifespan.
The ABS system excels in several key aspects. It utilizes wheel speed sensors to detect changes in wheel rotation. When the wheels are about to lock up, the electronic control unit pulses the braking system by releasing and reapplying pressure, maintaining wheel rotation. This allows you to steer flexibly even during high-speed braking, especially preventing skidding or rollovers on wet or snowy roads. Every time I drive a new car, I find the ABS design quite ingenious—it not only enhances responsiveness but also indirectly improves braking precision, reducing accident risks. Another notable feature is its adaptability to different road conditions, such as mud or gravel surfaces, ensuring more stable braking. However, I must emphasize that you shouldn't rely on ABS for speeding—maintaining a safe distance is always the top priority.
