The invention relates to the technical field of hybrid power vehicle energy management, and particularly discloses a hybrid power vehicle model prediction energy management strategy, which comprises the following steps: calculating energy required by a wheel end of each step length based on power required by the wheel end of each step length and a wheel end power correction factor; calculating energy required by the driving system based on the energy of the driving system; judging whether the energy required by the wheel end in each step length is equal to the energy required by a driving system or not, and if not, predictively adjusting the energy required by the driving system to be equal to the energy required by the driving system; and executing the predictively adjusted energy required by the driving system. According to the hybrid power vehicle model prediction energy management strategy provided by the invention, the energy required by the driving system is dynamically adjusted according to the energy required by the wheel end of each step length, and the operation of the driving system is pre-judged, executed and controlled, so that the energy consumption of the hybrid power vehicle model is reduced, and the fuel economy of the hybrid power vehicle model is improved; the limitation that predictive energy management cannot be carried out according to the travel destination in the prior art is solved.

    本发明涉及混动车能量管理技术领域,具体公开一种混动车型预测性能量管理策略,包括:基于每步长轮端所需功率和轮端功率修正因子计算得到每步长轮端所需能量;基于驱动系统能量计算得到驱动系统所需能量;判断所述每步长轮端所需能量与驱动系统所需能量是否相等,如果不相等,对所述驱动系统所需能量进行预测性调整至两者相等;执行预测性调整后的驱动系统所需能量。本发明提出的混动车型预测性能量管理策略,根据每步长轮端所需能量动态调整驱动系统所需能量,预判并执行控制驱动系统的运行,降低了混动车型车辆能耗,提升了混动车型车辆的燃油经济性,解决了现有技术中不能根据出行目的地进行预测性的能量管理的局限性。
