The invention relates to a hydrogen fuel vehicle hydrogen electricity energy management method and system and a motor vehicle, and the method comprises the following steps: obtaining the corresponding voltage and current of a vehicle power battery and a fuel battery at the current time period, and obtaining the corresponding average power of the power battery and the fuel battery; the sum of the two is the actual running power of the vehicle and the demand response power of the next time period; the driving behavior is determined according to the starting times of an accelerator pedal and a brake pedal in a set time period, the grade corresponding to the driving behavior is obtained according to the torque of a vehicle motor under the current working condition, the influence condition of the driving behavior on energy recovery is determined, and the energy recovery limiting range is determined according to the current SOC value of a power battery. The maximum braking torque, the maximum sliding torque and the optimal recovery torque are obtained; and according to the route of the vehicle in the set period, determining the driving mileage, obtaining the predicted SOC change trend in the corresponding period, and according to the SOC change trend, determining the residual SOC range of the vehicle returning to the designated place.

    本发明涉及氢燃料车辆氢电能量管理方法、系统及机动车辆,包括以下步骤:在当前时段获取车辆动力电池和燃料电池对应的电压和电流,得到动力电池和燃料电池对应的平均功率,两者的和为车辆实际运行功率和下一时段的需求响应功率;根据加速踏板和制动踏板在设定时间段内的启动次数确定驾驶行为,根据当前工况下车辆电机的扭矩得到驾驶行为对应的等级,确定驾驶行为对能量回收的影响情况,根据动力电池当前SOC值确定能量回收的限制范围,得到最大的制动扭矩和滑行扭矩,以及最佳的回收扭矩;根据设定周期内车辆的路线确定行驶里程,得到对应周期内预测的SOC变化趋势,根据SOC变化趋势确定车辆返回指定地点的剩余SOC范围。
