The invention discloses a starting control method and device for a hybrid power vehicle and the hybrid power vehicle. A hybrid power system of the hybrid power vehicle at least comprises an engine, a power motor, a gearbox, a first clutch and a second clutch. An engine is connected with the gearbox through the first clutch, the power motor and the second clutch in sequence. The method comprises the steps that whether the environment temperature is lower than a preset threshold value or not is judged; under the condition that the environment temperature is lower than the preset threshold value, whether the second clutch is in a disengagement state or a meshing state is judged; and under the condition that the second clutch is in the disengaged state, the first clutch is controlled to be in the engaged state, so that the started power motor assists the engine in starting. According to the technical scheme, the problem that the engine is difficult to start in the low-temperature environment can be solved, and the engine starting effect and efficiency are improved.
