摘要
在分析了同步器式机械变速器换挡过程的基础上,结合电控液压式AMT换挡操纵机构的工作原理,提出换挡过程的控制策略。它基于对液压系统的高速开关电磁阀的脉宽调制控制,实现了换挡过程的准确控制。通过台架试验,得到了电磁阀控制占空比与换挡力的关系。最后通过实车试验,证实了换挡控制策略的实用性。
On the baseof analysis on the shifting bined with the working principle of shifting mechanism of process of mechanical synchromesh transmission and cornelectro-hydraulic AMT, a control strategy for gear shifting is proposed, i.e. the accurate control of shifting process is realized based on the pulse width modulation （PWM） control for high speed on-off valve control and the shifting solenoid valve in hydraulic system. The relation between the duty cycles of solenoid force is established by bench test. Finally real vehicle tests verify the practicality of the shifting control strategy proposed.
