Road surface display device
A road surface display device mounted to an own vehicle includes: a road surface image control portion generating a road surface image which is displayed on a road surface ahead of the own vehicle and includes images each indicating an expected arrival zone where the own vehicle is expected to arrive at an expected arrival time; a detection portion obtaining display states of a different vehicle image, which is a road surface image displayed by a different vehicle, and an own vehicle image, which is the road surface image displayed by the own vehicle, and detecting a presence of overlapping or proximity between the two images; and a display adjustment portion, when the presence of overlapping or proximity is detected, displaying an image indicating a shorter expected arrival time in a region where the presence of overlapping or proximity is detected on the road surface.
1. A road surface display device, which is mounted to an own vehicle and displays an image on a road surface, comprising:
a control portion generating a road surface image including sub images, each of the sub images indicating an expected arrival zone where the own vehicle is expected to arrive at a corresponding predetermined expected arrival time, the sub images being arranged according to the respective expected arrival times, and the control portion displaying the road surface image on a road surface ahead of the own vehicle in a travel direction; and
a detection portion obtaining display states of a different vehicle image and an own vehicle image when the different vehicle image and the own vehicle image are displayed on the road surface, the different vehicle image being a road surface image displayed by a different vehicle equipped with the road surface display device, the own vehicle image being the road surface image displayed by the own vehicle, and the detection portion detecting a presence of overlapping or a presence of proximity between the different vehicle image and the own vehicle image based on the obtained display states, wherein
the control portion, when the presence of overlapping or the presence of proximity is detected by the detection portion, adjusts an output of to display one of the different vehicle image or the own vehicle image which indicates a shorter expected arrival time in a region where the presence of overlapping or the presence of proximity is detected on the road surface.
2. The road surface display device according to claim 1 , wherein,
when the presence of overlapping is detected by the detection portion and the different vehicle image indicates the shorter expected arrival time than the own vehicle image, the control portion displays the own vehicle image in a same manner as the different vehicle image at least in the region where the presence of overlapping is detected on the road surface.
3. The road surface display device according to claim 1 , wherein,
when the presence of overlapping is detected by the detection portion and the different vehicle image indicates the shorter expected arrival time than the own vehicle image, the control portion deactivates a display of the own vehicle image in the region where the presence of overlapping is detected on the road surface.
4. The road surface display device according to claim 1 , wherein,
when the presence of proximity is detected by the detection portion and the different vehicle image indicates the shorter expected arrival time than the own vehicle image, the control portion displays the own vehicle image in a same manner as the different vehicle image at least in the region where the presence of proximity is detected on the road surface.
5. A road surface display device, which is mounted to an own vehicle and displays an image on a road surface, comprising:
a control portion generating a road surface image including sub images, each of the sub images indicating an expected arrival zone where the own vehicle is expected to arrive at a corresponding predetermined expected arrival time, the sub images being arranged according to the respective expected arrival times, the control portion displaying the road surface image on a road surface ahead of the own vehicle in a travel direction, and the control portion displaying the sub images corresponding to respective expected arrival times in different manners; and
a detection portion obtaining display states of a different vehicle image and an own vehicle image when the different vehicle image and the own vehicle image are displayed on the road surface, the different vehicle image being a road surface image displayed by a different vehicle equipped with the road surface display device, the own vehicle image being the road surface image displayed by the own vehicle, and the detection portion detecting a presence of overlapping or a presence of proximity between one of the sub images of the different vehicle image and one of the sub images of the own vehicle image based on the obtained display states, wherein
the control portion, when the presence of overlapping or the presence of proximity is detected by the detection portion, adjusts an output to display the one of the sub images of the different vehicle image or the one of the sub images of the own vehicle image which indicates a shorter expected arrival time in a region where the presence of overlapping or the presence of proximity is detected on the road surface.
