The invention discloses a dual-motor hybrid power low-power starting control method and device and a vehicle, and relates to the technical field of vehicle engineering. The dual-motor hybrid power low-power starting control method comprises the following steps: S1, a generator applies continuously-increasing first torque to an engine; S2, the torque applied to the engine by the generator is increased to the first maximum torque; S3, the torque of the generator is switched into low-rotating-speed dragging torque TqStb, and the engine executes ignition and combustion actions; S4, after the engine is successfully ignited, the generator applies a second maximum torque to the engine until the real-time rotating speed P of the engine is greater than the third rotating speed Pspd6; and S5, the output torque of the generator is calculated. According to the method, under the condition that the available power of the battery is insufficient, the residence time of the real-time rotating speed of the engine in the low-speed resonance area is shortened, and the good starting NVH performance is guaranteed.
