METHOD FOR USING VEHICLE LIGHT TO PROJECT PATTERN, VEHICLE LIGHT SYSTEM, AND VEHICLE

The present invention relates to a method for using a vehicle light to project a pattern. The method comprises: receiving information about a pattern to be projected, in which the information about the pattern comprises a pattern to be projected and a projection priority; determining a projection position of the pattern according to the information about the pattern; and projecting the pattern at the projection position, wherein when multiple patterns to be protected exist, a pattern having the highest priority is protected. In embodiments of the present invention, projection information is effectively classified according to respective priorities, and the positions of various projection information in a projection region are planned, thereby ensuring that information having a highest priority is presented to a driver of a vehicle, drivers of other vehicles and pedestrians in a timely manner. A vehicle status and surrounding environment information are easily and clearly acquired, thereby greatly improving driving safety. The present invention further relates to a vehicle system and a vehicle.
