The invention discloses a hybrid electric vehicle, a power generation method and device thereof and a vehicle control unit. The method comprises the steps that position information of the hybrid electric vehicle, different vehicle speed interval proportions within preset time and different slope interval proportions of a road where the hybrid electric vehicle is located within the preset time are obtained; the current working condition of the hybrid electric vehicle is determined according to the position information, the proportions of the different vehicle speed intervals and the proportions of the different slope intervals; acquiring corresponding target generation power according to the working condition; and controlling the hybrid electric vehicle to generate power according to the target generated power. Therefore, the current working condition is determined by obtaining the position information of the hybrid power vehicle, the proportions of different vehicle speed intervals and the proportions of different slope intervals, so that the vehicle running working condition prediction is more reasonable, and meanwhile, different power generation strategies are adopted for power generation according to different working conditions; and the whole vehicle power generation requirement of the hybrid power vehicle under different working conditions and low SOC states is met, so that the purpose of improving the fuel economy of the hybrid power vehicle is achieved.

    本发明公开了一种混合动力汽车及其发电方法、装置及整车控制器,其中方法包括:获取混合动力汽车的位置信息、预设时间内的不同车速区间占比和预设时间内混合动力汽车所处道路的不同坡度区间占比;根据位置信息、不同车速区间占比和不同坡度区间占比确定混合动力汽车当前所处工况;根据工况获取相应的目标发电功率;根据目标发电功率控制混合动力汽车进行发电。由此,通过获取混合动力车辆的位置信息、不同车速区间占比和不同坡度区间占比来确定当前所处工况,使得车辆行驶工况预测更加合理,同时根据不同工况下采用不同的发电策略进行发电,满足了混合动力车辆在不同工况低SOC状态下的整车发电需求,从而达到改善混合动力汽车燃油经济性的目的。
