Comparison between Saifu ABS and Bosch ABS
2 Answers
Saifu ABS is slightly better than Bosch ABS. Working principle of ABS: During braking, the 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 begins to lock up, and keeps the braking force unchanged. If the wheel continues to lock up, the normally closed output solenoid valve is opened, causing the braking pressure on that wheel to drop rapidly 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. Functions of ABS: Maximize the effectiveness of the brake, shorten braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing good steering control. Avoid severe friction between tires and the ground, reducing tire wear.
I've been playing with cars for over a decade, and ABS systems are quite interesting to compare. SAIFF ABS is commonly found in high-end brands, offering smoother braking control on slippery roads with rapid response. Bosch ABS has higher popularity and is widely used in economy cars—safe and reliable but feels slightly stiffer in operation. In actual driving, both prevent wheel lock-up, though SAIFF technology performs more delicately on complex road surfaces. Price-wise, Bosch parts are cheaper and easier to replace, while SAIFF repairs might cost more. Considering vehicle usage, performance enthusiasts may prefer SAIFF, while pragmatists would choose Bosch. For daily use, the difference is minimal, and both ensure safety without issues.
