Flow guiding device, control method of flow guiding device and vehicle

The invention relates to the technical field of motor vehicles, in particular to a flow guiding device, a control method of the flow guiding device and a vehicle. The flow guide bottom plate is arranged at the top of the cab; the flow guide piece is arranged between the flow guide main plate and the flow guide bottom plate, and the flow guide piece rotates in a first plane so as to adjust the transverse angle of airflow; the flow guide sheets can stretch out and draw back in the first direction so as to adjust the height between the flow guide main plate and the flow guide bottom plate. The flow guide piece rotates in the first plane to adjust the transverse angle of airflow, the flow guide piece is telescopic in the first direction to adjust the height between the flow guide main plate and the flow guide bottom plate, and by adjusting the height and angle of the flow guide device, the angle of the flow meter for the airflow entering the air guide hole can be controlled; through angle adjustment of the flow d
