摘　　要：针对汽车ABS系统轮速信号的采集与处理，对汽车ABS系统电磁感应式轮速传感器的工作原理、信号特征特性进行了分析，设计了由低通滤波电路和施密特触发器构成的信号处理电路，并在proteus7．2环境下进行模拟仿真研究，结果表明电路工作稳定可靠、抗干扰性强。The paper analyses the working principle of electromagnetic speed sensor and its signal characteristics in anti-lock breaking system aiming at the acqusition and processing of the wheel speed signal in ABS, and presents the signal processing circuit, which consists of low pass filter and Schmitt trigger. The corresponding simulations under the Proteus 7. 2 environment and experiments show that the circuit is reliable and could minimize the effect of electromagneticinterference.
