Comparison between Saifu ABS and Bosch ABS?
3 Answers
Saifu ABS is slightly better than Bosch ABS. ABS, the full name is Antilock Brake System. Working principle of ABS: During braking, ABS can quickly determine the wheel lock state based on the speed signals from each wheel speed sensor, and close the normally open input solenoid valve on the wheel that is starting to lock, keeping the braking force unchanged. If the wheel continues to lock, the normally closed output solenoid valve is opened, and the braking pressure on this wheel rapidly decreases due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking due to excessive braking force. This keeps the braking state at the optimal point (slip rate S of 20%), achieving the best braking effect and the highest driving safety. Functions of ABS: Fully utilize the efficiency of the brake, shortening braking time and distance. It can effectively prevent vehicle sideslip and tail swing during emergency braking, ensuring good driving stability. It allows steering during emergency braking, providing good steering control. It avoids severe friction between the tire and the ground, reducing tire wear.
I often encounter ABS issues when repairing cars, and the differences between SAIE and Bosch are quite noticeable. Bosch ABS systems respond faster, especially during emergency braking on icy roads, where you can feel a higher pedal pulsation frequency and better vehicle stability. SAIE's advantage lies in its simpler and more durable structure, lower fuel quality requirements, and about 30% lower maintenance costs. However, Bosch's electronic control system is more precise, with more stable ESP integration, making it suitable for high-end models. I've experienced SAIE systems engaging slightly slower during hard braking in continuous curves, while Bosch performs more reliably under the same conditions. For long-term use, Bosch parts are more expensive but last longer, whereas SAIE is more economical and suitable for regular family cars.
As an automotive parts wholesaler, there are different considerations when sourcing these two types of ABS systems. Bosch ABS holds a dominant market share, especially in German vehicles, with its modular design facilitating upgrades, though individual units are 30% more expensive. Saifu has a larger share in domestic vehicles, offering strong compatibility and simpler repairs. User feedback indicates Bosch performs more stably on wet roads, while Saifu proves more reliable in high-altitude areas. In durability tests, Bosch sensors last longer, but Saifu's hydraulic units show better corrosion resistance. Currently, many repair shops prefer Bosch despite its higher purchase price, due to lower return rates and higher customer satisfaction. Saifu is suitable for budget-conscious car owners, being fully adequate for daily use.
