The invention discloses a vehicle energy management method, device and system, a storage medium and a vehicle control unit, and the method comprises the steps: obtaining front road condition information, and obtaining the information of a congested road section when determining that the congested road section exists in front according to the front road condition information; estimating the consumed electric quantity of the congested road section according to the congested road section information, and determining a congested target SOC according to the consumed electric quantity of the congested road section; and charging control is carried out on a power battery of the hybrid vehicle according to the congestion target SOC, so that the SOC of the power battery meets the electric quantity requirement of the hybrid vehicle for passing through the congestion road section in a pure electric mode when the hybrid vehicle enters the congestion road section. Therefore, before the hybrid power vehicle enters the congested road section, the SOC balance point of the hybrid power vehicle is raised in advance, so that the internal combustion engine is prevented from being frequently started and stopped when the hybrid power vehicle passes through the congested road section, and the driving and riding comfort is improved.

    本发明公开了一种车辆能量管理方法、装置、系统和存储介质与整车控制器,其中,包括:获取前方路况信息,并根据前方路况信息确定前方存在拥堵路段时获取拥堵路段信息;根据拥堵路段信息预估拥堵路段的消耗电量,并根据拥堵路段的消耗电量确定拥堵目标SOC;以及根据拥堵目标SOC对混合动力车辆的动力电池进行充电控制,以便混合动力车辆进入拥堵路段时动力电池的SOC满足混合动力车辆以纯电模式通过拥堵路段的电量需求。由此,在混合动力车辆进入拥堵路段之前,提前提高混合动力车辆的SOC平衡点,从而,避免混合动力车辆在通过拥挤路段过程中,内燃机频繁启停,提升驾乘舒适性。
