【摘要】 通过对地下铲运机的节能换挡策略进行研究,发现地下铲运机油门或载荷发生较大变化时,传统节能换挡策略会出现重复错误的换挡。通过加入对换挡趋势的判断,避免了地下铲运机应用节能换挡策略时出现的重复错误换挡,为地下铲运机及其他装有液力变矩器的车辆换挡策略的制定提供借鉴。更多还原

【Abstract】 Through the research on LHD energy-conserving shifting strategy,it is found that the traditional energy-conserving shifting strategy gives the repeated and wrong gear when the throttle or load changes.LHD can avoid the repeated and wrong gear through adding the judgment of gear tendency,when LHD use energy-conserving shifting strategy.The follow-up shifting strategy study of LHD and other vehicles which install hydraulic converters can use it as reference.更多还原
