介绍了目前摩托车换档拨叉自动检测系统的测试原理及其校正技术,探讨了该校正技术在应用中存在的一些问题。基于当前的计算机、传感器技术,根据最小均方误差理论,提出了一种改进的自校正技术。该自校正技术抛弃了传统的机械修复模块。它大幅度地降低了系统的硬件成本,极大地延长了系统的使用寿命,提高了系统的测试精度、稳定性、可靠性,简化了其自校正操作。 The test principle and correction technology of automatic detection system of shift forks are introduced. Some problems in the application of the correction technology are discussed. Based on the current computer and sensor technology, an improved self-tuning technique is proposed based on the minimum mean square error theory. The self-correction technology abandoned the traditional mechanical repair module. It greatly reduces the hardware cost of the system, greatly prolongs the service life of the system, improves the testing accuracy, stability and reliability of the system, and simplifies the self-calibration operation.
