The invention discloses an energy management method of a hybrid power vehicle, an energy management device of the hybrid power vehicle and a vehicle control unit, and the energy management method of the hybrid power vehicle comprises the following steps: obtaining driving habit information of a current driver, acquiring the required torque of the vehicle under each working condition according to the driving habit information of the current driver, and calculating the discharge limit SOC of a power battery according to the required torque; obtaining a discharge target SOC of the power battery, and taking a larger value in the discharge limit SOC and the discharge target SOC as a discharge limit threshold value of the power battery; and when it is determined that the actual SOC of the power battery is smaller than or equal to the discharge limiting threshold value, an engine is controlled to be started. The energy management method of the hybrid power vehicle has the advantages that charging and discharging of the power battery are reasonable, and the service life of the power battery is long.

    本发明公开了一种混合动力车辆的能量管理方法、混合动力车辆的能量管理装置和整车控制器,所述混合动力车辆的能量管理方法包括:获取当前驾驶员的驾驶习惯信息,并根据所述当前驾驶员的驾驶习惯信息获取车辆在每种工况下需求扭矩,以及根据所述需求扭矩计算动力电池的放电限制SOC;获取所述动力电池的放电目标SOC,并取所述放电限制SOC和所述放电目标SOC中的较大值作为所述动力电池的放电限制阈值;在确定所述动力电池的实际SOC小于等于所述放电限制阈值时,控制发动机启动。根据本发明实施例的混合动力车辆的能量管理方法具有动力电池充放电合理、动力电池使用寿命长等优点。
