摘要
论述了电子踏板信号的一般处理方法,包括信号调理、故障诊断以及数据定标过程.列举了一阶低通滤波和防脉冲扰动中位值滤波算法;提出了基于宽度检测和频度检测的故障诊断策略;描述了传感器的定标过程;通过Matlab/Simulink建模仿真验证了其可靠性.
The general rules for statistical analysis of electronic pedal data are discussed,including signal conditioning,fault diagnosis and data scaling.The algorithm of 1st-Order Low-Pass Filter and Pulse-Eliminate-Average Filter are introduced.The strategy for fault diagnosis is put forward based on width check and frequency check,and the procedures of data scaling are described for the sensors.The algorithm and strategy are verified by the simulation on Matlab/Simulink.
