Abstract: The typical hybrid technologies and their limitations in energy conservation and emission re.duction are discussed. The layout scheme of the new hydraulic-drive hybrid vehicle , incorporating theAlMS module, is analyzed. The working principle, applications , and key technologies of the AlMS mod.ule are examined in detail. Additionally , the development trends for the new hydraulic-drive hybrid vehi.ele are proposed , including the optimization of AlMS control strategies , improvements in overall vehiclereliability , and the optimization of vehicle costs and market applications. Long-tem prospects are also explored , such as the intelligent automation of vehicles, environmental frendliness , sustainable develop.ment, and the integration of multiple technologies.
