The invention relates to a control method and device of a hybrid power vehicle, a medium and equipment. The method comprises the steps that if an instruction for converting a current series drive mode into a direct drive mode is received, a target gear, the target torque of a crankshaft and the target rotating speed of the crankshaft are determined according to the current state of a vehicle, the series drive mode is driven by a drive motor, and an engine participates in power generation; the direct driving mode is jointly driven by an engine and a driving motor; the gearbox is controlled to start to be switched to the target gear; controlling the rotating speed of the crankshaft to reach the target rotating speed; if it is judged that the gearbox is switched to the target gear and the two sides of the clutch are synchronized, the torque of the clutch is controlled to be increased to a preset value; and if the state of the clutch reaches the slipping state, the torque of the crankshaft is controlled to be increased until the target torque is reached. According to the method, the transmission efficiency of the power transmission system is high, the mode switching time is short, the abrasion and impact load of elements are reduced, and the driving and riding comfort is improved.

    本公开涉及一种混合动力车辆的控制方法、装置、介质和设备。方法包括:若接收到将当前的串联驱动模式转换至直接驱动模式的指令,则根据车辆的当前状态确定目标挡位、曲轴的目标扭矩以及曲轴的目标转速,串联驱动模式为由驱动电机驱动且发动机参与发电,直接驱动模式为由发动机和驱动电机共同驱动;控制变速箱开始向目标挡位切换;控制将曲轴的转速达到目标转速;若判定变速箱已切换至目标挡位,且离合器两侧已达到同步,则控制将离合器的扭矩增大到预定值;若离合器的状态达到打滑状态,则控制将曲轴的扭矩增大,直至达到目标扭矩。该方法动力传输系统的传递效率较高,模式切换的用时较短,减小了元件的磨损及冲击载荷,提升了驾乘舒适性。
