Road surface drawing device for vehicle and road surface drawing method for vehicle

A road surface drawing method for a vehicle for projecting an image based on a drawing pattern onto a road surface, the road surface drawing method comprising:

• a road surface drawing step of irradiating the road surface with light to project the image on the road surface;
• and
• an operation state acquisition step of acquiring an operation state of a vehicle,
• wherein control is performed in a reverse mode in response to determining that the operation state is reverse operation, and
• the image is turned off in response to determining that the operation state is not the reverse operation.

A road surface drawing device for a vehicle and for projecting an image based on a drawing pattern onto a road surface, the road surface drawing device comprising:

• a road surface drawing device configured to turn on the drawing pattern;
• an imaging device configured to capture a projection drawing pattern projected onto the road surface;
• a comparison device configured to compare the projection drawing pattern with a basic drawing pattern;
• and
• a controller configured to, in a case where there is a difference between the projection drawing pattern and the basic drawing pattern, change a lighting state of the road surface drawing device.
