The invention relates to a control method and device of a plug-in extended-range hybrid power vehicle, a medium, equipment and a vehicle. The method comprises the steps that in the vehicle running process, if a power battery breaks down, an engine is controlled to run at a preset rotating speed and drive a generator, so that the generator supplies power to a driving motor, and the driving motor drives a vehicle to run; the required power of the vehicle is determined; whether the required power is matched with the generated power of the generator is judged; and if judging that the required power is not matched with the generated power of the generator, the low-voltage storage battery is controlled to participate in distribution of the power supply quantity of the driving motor while the torque of the engine and the torque of the generator are adjusted. In the way, the low-voltage storage battery is used as a buffer for adjusting balance, large fluctuation of bus voltage is avoided, andfrequent alarming is avoided. Even if the engine is set to run at a lower rotating speed, the accuracy of torque adjustment can also be ensured, and the riding comfort and economy are improved.

    本公开涉及一种插电增程式混合动力车辆的控制方法和装置、介质、设备、车辆。该方法包括:在车辆行驶过程中,若动力电池发生故障,则控制发动机以预定转速运行并带动发电机,以使发电机为驱动电机供电,驱动电机驱动车辆行驶;确定车辆的需求功率;判断需求功率和发电机的发电功率是否匹配;若判定需求功率和发电机的发电功率不匹配,则在调节发动机的扭矩和发电机的扭矩的同时,控制低压蓄电池参与驱动电机供电电量的分配。这样,利用低压蓄电池作为调节平衡的缓冲器,避免了母线电压的较大波动和频繁地报警。即使将发动机设置为以较低的转速运行,也能够保证扭矩调整的精确性,提升了乘车舒适性和经济性。
