摘　　要：根据液压机械无级变速器(HMCVT)的控制要求和台架试验的特点,在对HMCVT的段内无级变速原理和同步换段条件分析的基础上,设计了手动控制的硬件系统,制定了控制策略和控制流程,编写了HMCVT的手动控制程序。台架试验表明该控制系统能及时平稳地实现变速器的连续无级变速并自动完成换段动作,达到了设计目的。According to the characteristics of bench test and control requirements of hydro-mechanical continuously variable transmission(HMCVT),a hardware system of manual control is designed.Control strategy and process are formulated and a manual control program is programmed for HMCVT based on the analysis of stepless speed change principle in each range and synchronous shift range conditions of HMCVT.The bench test indicates that control system can realize continuously stepless change of transmission,and shift range automatically.
