AMT换挡冲击控制策略的优化方案

Optimization Scheme of AMT Shift Impact Control Strategies

介绍了机械式自动变速器(AMT)换挡冲击的产生原因,主要有机械、油路、电路三方面的故障原因引起的冲击和自身结构、工作原理引起的动力中断而产生的换挡冲击;总结了目前国内外针对AMT换挡动力中断问题的研究进展及解决方案,大多数学者专家都是通过改善动力传动系统结构或者从控制策略上进行优化;最后综合国内外的研究现状,提出了AMT换挡冲击控制策略的优化应从发动机、离合器、变速器的综合控制、采用模糊-神经网络控制、增强控制系统的软件功能以及采用高速运算器、电动执行器四方面展开研究。

This paper introduces causes of the shift shock of automatic mechanical transmission （AMT）. The fault of machinery, oil circuit, circuit and the interruption of power shift are caused by its structure, working principle. Summarized the overseas and domestic research status about AMT shift power interrup- tion research evolve and solutions. Most of scholars and experts came up with improving the structure of the power transmission system or optimizing the control strategy. Comprehensive research status both at home and abroad, the author puts forward the control strategy optimization of AMT shift impact at the end of the paper . Integrated control of engine, clutch and the transmission, fuzzy-neural network control, strengthen the function of software of the control system and high speed arithmetic unit application, electric actuators application should do next.
