The invention relates to the technical field of vehicles, and particularly discloses a hybrid power system gear shifting control method and device, a vehicle and a storage medium, and the hybrid power system gear shifting control method comprises the steps that when it is confirmed that the vehicle has a gear shifting demand in the advancing process, a target gear shifting interval is determined based on the load, the gradient and the acceleration; on the basis of the accelerator opening degree and the vehicle speed, whether the vehicle can be kept stable in the gear or not after being switched to all the pre-selected gears in the target gear shifting interval is sequentially evaluated, and the pre-selected gears which can be kept stable in the gear serve as target gears to be selected; when the vehicle executes the upshift operation, the current gear of the vehicle is switched to the gear with the highest gear in the target gears to be selected; or when the vehicle executes the downshift operation, the current gear of the vehicle is switched to the lowest gear in the to-be-selected target gears, it can be guaranteed that after the vehicle executes the gear shifting operation, the vehicle can be kept in the gear relatively stably, the situation that gear shifting is needed again due to the fact that the gears are not stable after gear shifting is conducted is avoided, and the gear shifting frequency is reduced.

    本发明涉及车辆技术领域,具体公开了一种混合动力系统换挡控制方法、装置、车辆及存储介质,该混合动力系统换挡控制方法,在确认车辆行进过程中具有换挡需求时,基于载重、坡度和加速度确定目标换挡区间;基于油门开度和车速依次评估车辆切换至目标换挡区间内的各个预选挡位后能否保持稳定在挡,并将能够保持稳定在挡的预选挡位作为待选目标挡位;当车辆执行升挡操作时,将车辆的当前挡位切换至待选目标挡位中的挡位最高的一个;或者,当车辆执行降挡操作时,将车辆的当前挡位切换至待选目标挡位中的挡位最低的一个,可保证车辆执行换挡操作后,能够相对稳定地保持在挡,避免换挡后因挡位不稳定再次需要换挡的情况,并降低换挡频率。
