摘　　要：为提高动力性并实现节能减排,以并联式混合动力装载机为例研究工程车辆的混合动力系统自动变速控制方法。考虑作业载荷对最优挡位特性的影响,提出以'油门开度、车速、作业载荷系数'为控制参数的新型自动变速控制原理,提出了节能换挡规律、动力换挡规律和综合换挡规律。研究结果表明:在满足正常工作要求的前提下,换挡规律准确有效,挡位变换与载荷变化一致性较好,提高了车辆动力性和能量利用率。To improve the power performance and reduce energy consumption and environmental pollution, a parallel hybrid loader is taken as a sample to research the automatic shift technology of hybrid power engineering vehicles. The influence of the operating load on the optimal gear was taken into account. The throttle, speed and operating load {actor were considered as the control parameters for the new automatic shift control scheme. Energy saving schedule, power shift schedule and comprehensive shift schedule were proposed. Results show under the premise of meeting the normal requirements, the proposed shift schedule is accurate and effective, the gear change and load change have good consistency. The power performance is improved and the energy consumption is reduced.
