摘　　要：介绍了一种单体泵电控系统转速信号处理技术,通过转速信号齿周期合理性检测和齿间合理性系数的正确选择与标定,实现了转速信号的正确采集,台架试验表明,该项转速信号处理技术能够准确地滤除干扰信号,使电控系统正确采集曲轴和凸轮轴转速信号,完成喷油正时和油量的正确控制。A signal processing technology for unit pump electronic control system was introduced in the paper.Rotational speed signal can be sampled correctly through reasonable detection and calibration of signal period and tooth interval coefficient.It was showed by bench-test results that noise signal can be filtered well through signal processing technology presented in this paper.Camshaft and crank speed signal of electronic control system can be sampled exactly,so injection timing and fuel can be controlled precisely.
