基于Willans Line的双轴驱动混合动力越野车实时能量管理

为了实现混合动力越野车的实时能量管理，建立了其动力系统的动力学模型，提出利用发动机和电机的Willans Line 模型，建立基于WL-ECMS能量管理控制方法的发动机和电机最优输出功率模型。硬件在环试验结果表明，基于WL-ECMS的控制方法可以实现混合动力越野车基本的能量管理，车速跟随误差在合理的范围内，与基于ECMS的能量管理控制方法相比，其百公里油耗仅提高3.03%，与基于规则的能量管理控制方法相比，其百公里油耗低12.07%，且每一个时间步长程序的相对运行时间由基于ECMS方法的100下降到1.65，与基于规则方法的1.07相当，实现了混合动力越野车实时能量管理。

Real-time Energy Management of a Dual-axle-driven Off-road HEV Based on Willans Line

In order to achieve the real-time energy management of an off-road HEV, the dynamics models of the power components were built. A method was proposed based on the Willans Line models of engine and motor, and the optimal output power models of the engine and motor were built based on the WL-ECMS. HIL experimental results show that the WL-ECMS-based strategy can realize the basic energy management of the off-road HEV, and the velocity errors are kept within a desired range. The hundred kilometers fuel consumption with WL-ECMS strategy is only 3.03% more than that of ECMS and 12.07% less than that of the rule-based strategy. Furthermore, the computational time for a single step is reduced to 1.65 from that of 100 with ECMS, and it is comparable with the 1.07 of that of the rule-based strategy, thus the real-time energy management of the off-road HEV is realized.
