The invention provides a hybrid power vehicle and a control method thereof, a storage medium and a vehicle control unit, an altitude sensor and a positioning system are arranged on the hybrid power vehicle, and the method comprises the steps that a first height is obtained through the altitude sensor, and a second height is obtained through the positioning system; the first height and the second height are mutually corrected, and the altitude of the environment where the hybrid vehicle is located is obtained; obtaining a target power guarantee SOC according to the altitude and a preset power guarantee SOC; and the SOC of a power battery of the hybrid power vehicle is obtained, and the hybrid power vehicle is controlled according to the target power guarantee SOC and the SOC of the power battery. Through the control method of the hybrid power vehicle, the accuracy of the obtained altitude can be improved through mutual correction of the two heights, the energy management capacity of the hybrid power vehicle in a high-altitude area can be enhanced by adjusting the power guaranteeing SOC according to the altitude, the dynamic property, the power guaranteeing property and the economical efficiency of the vehicle are improved, the NVH experience of passengers is guaranteed, and the safety of the hybrid power vehicle is improved. The energy consumption of the vehicle is reduced.

    本公开提出了一种混合动力车辆及其控制方法、存储介质和整车控制器,混合动力车辆上设有海拔传感器和定位系统,方法包括:通过海拔传感器获取第一高度,并通过定位系统获取第二高度;对第一高度和第二高度进行互校,得到混合动力车辆所处环境的海拔高度;根据海拔高度和预设保电SOC得到目标保电SOC;获取混合动力车辆的动力电池的SOC,并根据目标保电SOC和动力电池的SOC对混合动力车辆进行控制。通过该混合动力车辆的控制方法,通过两高度的互校可提高所得到海拔高度的准确性,通过根据海拔高度调整保电SOC,可增强混合动力车辆在高海拔地区的能量管理能力,提升车辆的动力性、保电性和经济性,并且保障乘客的NVH体验,降低车辆的能耗。
