The invention belongs to the technical field of power split type structure hybrid power vehicle control, and particularly provides a power split type hybrid power heavy truck gear switching control method and device and a medium. The method comprises the following steps that the actual rotating speed and the actual torque of a motor fed back by a motor controller in real time through a message and the actual rotating speed and the actual output torque of an engine fed back by an engine controller in real time through the message are received; judging a driving mode of a power system according to the power structure connection mode of the current vehicle; and gear switching control is carried out according to different driving modes. The gear shifting processes under the five different working modes are controlled and adjusted respectively, normal gear shifting is guaranteed to the maximum extent, and therefore the running smoothness of the whole vehicle is guaranteed, and the driving feeling of the vehicle is improved.

    本发明属于功率分流式结构混动车辆控制技术领域,具体提供一种功率分流式混动重卡挡位切换控制方法、设备及介质,所述方法包括如下步骤:接收电机控制器通过报文实时反馈的电机实际转速和实际扭矩以及发动机控制器通过报文实时反馈的发动机的实际转速和实际输出扭矩;根据当前车辆处于的动力结构连接模式判断动力系统的驱动模式;根据不同的驱动模式进行挡位切换控制。5种不同工作模式下的换挡过程实现分别控制调节,最大限度的保证了挡位的正常切换,从而保证整车的运行平顺性,提高车辆驾驶感受。
