Road surface drawing device
A road surface drawing device is mounted on a vehicle. When the travel direction of a vehicle is changed by an operation performed by the driver of the vehicle, the road surface drawing device draws a pattern by means of light in an area, on a road surface, that includes the side toward which the travel direction is being changed with respect to the vehicle, the pattern indicating the change in travel direction. The pattern includes a plurality of band-shaped patterns spaced apart from each other in vehicle width directions. The plurality of band-shaped patterns are such that the closer the band-shaped pattern is to the outside in the vehicle width direction, the longer the pattern is in vehicle longitudinal directions and the more the front end of the pattern is positioned forwardly.
1 . A road surface drawing apparatus mounted on a vehicle, the road surface drawing apparatus drawing by means of light, when a travel direction of the vehicle is changed based on an operation by a driver of the vehicle, a pattern for notifying a change in the travel direction, in an area on a road surface including a side to which the travel direction is to be changed, relative to the vehicle,
the pattern including a plurality of band-shaped patterns separated from one another in a vehicle width direction of the vehicle,
the plurality of band-shaped patterns being arranged such that the further on an outer side in the vehicle width direction, which is a side in a direction away from the vehicle in the vehicle width direction, a band-shaped pattern is, the longer in a vehicle length direction of the vehicle the band-shaped pattern is, and the further on a front side in the vehicle length direction a front end thereof is located.
2 . The road surface drawing apparatus according to claim 1 , wherein an extension direction of inner-side band-shaped patterns including at least a band-shaped pattern located innermost on an inner side in a vehicle width direction is inclined relative to the vehicle length direction, and front ends of the inner-side band-shaped patterns are located further on the inner side in the vehicle width direction than rear ends.
3 . The road surface drawing apparatus according to claim 2 , wherein widths of the rear ends of the inner-side band-shaped patterns are smaller than widths of the front ends, respectively.
4 . The road surface drawing apparatus according to claim 1 , comprising a drawing control unit drawing the plurality of band-shaped patterns in order starting from a band-shaped pattern on the inner side in the vehicle width direction.
