The invention discloses a control method suitable for parallel running energy management of a series-parallel hybrid electric vehicle. The control method comprises the steps that current running state parameters of the vehicle are obtained; according to the current driving state parameters of the vehicle, the whole vehicle demand driving power of the vehicle in the current state is calculated; distributing the required driving power of the whole vehicle into engine driving power and motor driving power; determining predicted working points of the engine and the motor according to a power distribution result; judging whether the working points of the two are economic; if the working points are economical, engine driving power and motor driving power are output; and if at least one working point deviates from the economic area, returning to the power distribution stage. According to the control method suitable for parallel running energy management of the series-parallel hybrid electric vehicle, the optimal energy control scheme is selected according to the working characteristics of the engine and the performance of the driving motor while the running power performance of the vehicle is kept, and corresponding distribution and adjustment are carried out, so that the purpose of improving the economic performance of fuel oil is achieved.
本发明公开了一种适用于串并联混动汽车并联行驶能量管理的控制方法,包括:获取车辆当前行驶状态参数;根据车辆当前行驶状态参数,计算车辆当前状态下的整车需求驱动功率;将整车需求驱动功率分配为发动机驱动功率和电机驱动功率;根据功率分配结果,确定发动机和电机的预计工作点;判断二者的工作点是否经济;若工作点均经济,则输出发动机驱动功率和电机驱动功率;若至少一个工作点偏离经济区域,则返回功率分配阶段。本发明的适用于串并联混动汽车并联行驶能量管理的控制方法,在保持车辆行驶动力性能的同时,根据发动机自身的工作特性、驱动电机的性能,挑选出最优能量控制方案,并进行相应分配调节,从而达到提升燃油经济性能的目的。
