防抱死制动系统(Anti-lock Braking System简称ABS)是用电磁传感器测量车轮速度,当传感器检测到车轮抱死时,制动管路上的电机启动以控制阀口的大小,从而调节制动压力。 早期的汽车上的ABS主要是机械式ABS,它是利用惯性飞轮探测车轮是否抱死,从而减小制动力,因为功能简单、适应性差等原因,应用范围很窄。随着大规模及超大规模集成电路技术的发展,微处理器被应用于ABS中,使ABS实现了智能化,可以完成复杂的计算及逻辑控制,从而奠定了现代汽车ABS的基础和基本模式。目前所说的ABS是在传统气压或液压制动系统的基础上,采用电子技术,在制动时防止车轮抱死的机电一体化系统。 Anti-lock Braking System (ABS) is the use of electromagnetic sensors to measure the wheel speed, when the sensor detects the wheel lock, the brake line motor starts to control the size of the valve port, which adjust the brake pressure. Early ABS on the car is mainly mechanical ABS, which is the use of inertial flywheel to detect wheel locking, thereby reducing the braking force, because of simple, poor adaptability and other reasons, the application is very narrow. With the development of large-scale and VLSI technologies, microprocessors are used in ABS to intelligently and intelligently implement ABS, thus completing the complicated calculation and logic control, thus laying the foundation and basic mode of modern ABS. The so-called ABS is based on the traditional pneumatic or hydraulic braking system, the use of electronic technology to prevent wheel lock in the braking system mechatronic.
