Abstract

A vehicle display control apparatus mounted on a vehicle includes a display control portion that controls a head-up display device displaying an image by superimposing the image on a view visible to a driver of the vehicle through a windshield of the vehicle, and a condition determination portion that determines whether a condition under which the vehicle should slow down is satisfied. The display control portion causes, based on a determination of the condition determination portion that the condition is satisfied, the head-up display device to display an object that does not actually exist on a road under circumstances where the condition is satisfied, as an illusion image that produces an optical illusion appearing that a road surface viewed from the driver flows faster than an actual speed in an opposite direction to a travel direction by superimposing the illusion image on the view.

First claim

The invention claimed is:

1. A vehicle display control apparatus mounted on a vehicle, comprising:
a controller that includes
a display control portion configured to control a head-up display device displaying an image by superimposing the image on a view visible to a driver of the vehicle through a windshield of the vehicle, and
a condition determination portion configured to determine whether a condition under which the vehicle should slow down is satisfied,

wherein:
the display control portion is configured to cause, based on a determination of the condition determination portion that the condition under which the vehicle should slow down is satisfied, the head-up display device to display an object that does not actually exist on a road under circumstances where the condition is satisfied, as an illusion image that produces an optical illusion appearing that a road surface viewed from the driver moves faster than an actual speed of the vehicle in an opposite direction to a travel direction of the vehicle by superimposing the illusion image on the view visible to the driver through the windshield.

2. The vehicle display control apparatus according to claim 1 , wherein:
the display control portion successively displays the illusion image to produce the optical illusion continuously, based on the determination of the condition determination portion that the condition is satisfied.

3. The vehicle display control apparatus according to claim 2 , further comprising:
a behavior determination portion configured to determine whether the driver performs a desirable behavior for road traffic under the circumstances where the condition is satisfied,
wherein:
the display control portion does not display the illusion image when the behavior determination portion determines that the driver performs the desirable behavior for road traffic under the circumstances where the condition is satisfied.

4. The vehicle display control apparatus according to claim 1 , further comprising:
a slowdown degree specifying portion configured to specify a degree at which the vehicle should slow down,
wherein:
when the display control portion displays the illusion image that produces the optical illusion appearing that the road surface viewed from the driver moves faster than the actual speed of the vehicle in the opposite direction to the travel direction of the vehicle,
the display control portion displays the illusion image appearing that the road surface viewed from the driver moves in the opposite direction to the travel direction of the vehicle at a higher speed as the degree of slowdown specified by the slowdown degree specifying portion increases.

5. The vehicle display control apparatus according to claim 1 , wherein:
the display control portion displays the illusion image appearing as marks, each of the marks becomes shorter in a vehicle width direction as the marks move in the travel direction of the vehicle and are aligned intermittently along the road surface in the travel direction of the vehicle, move in the opposite direction to the travel direction of the vehicle, and the display control portion produces the optical illusion appearing that the road surface viewed from the driver moves faster than the actual speed of the vehicle in the opposite direction to the travel direction of the vehicle.

6. The vehicle display control apparatus according to claim 5 , wherein:
the display control portion displays the marks intermittently aligned so that the marks appear to be aligned on a lane boundary of a lane the vehicle is travelling.
