The invention discloses a PHEV adaptive optimization energy management control method based on driving condition prediction, and the method comprises the steps: obtaining future path information through an intelligent traffic system and a vehicle-mounted navigation system, and generating an energy consumption equivalent prediction condition of a future path; establishing a reference ECMS control model, and searching for an optimal ECMS equivalent factor lambda opt and a reference SOCref by taking the energy consumption equivalent prediction working condition as input and taking the lowest oilconsumption as an optimization target; on the basis of the optimal equivalent factor lambda opt and a reference SOCref, correcting the optimal equivalent factor lambda opt according to the actual SOCand the reference SOCref under the actual driving working condition to form a self-adaptive ECMS control model, and calculating the engine torque and the motor torque with optimal oil consumption; andtransmitting the target torques of the engine and the motor and a switching instruction to a bottom layer controller, and distributing the power of the whole vehicle to realize PHEV energy managementand control.

    本发明公开了一种基于行驶工况预测的PHEV自适应优化能量管理控制方法,通过智能交通系统、车载导航系统获取未来路径信息,生成未来路径的能耗等效预测工况;建立参考ECMS控制模型,以能耗等效预测工况作为输入,以油耗最低为优化目标,寻求最优的ECMS等效因子λopt和参考SOCref;基于最优等效因子λopt以及参考SOCref,在实际行驶工况下,根据实际SOC和所述参考SOCref对所述最优等效因子λopt进行修正,形成自适应ECMS控制模型,计算油耗最优的发动机转矩和电机转矩;将发动机和电机的目标转矩及开关指令传递给底层控制器,对整车的动力进行分配,实现PHEV能量管理与控制。
