1. A prompting device is characterized in that a prompting device is provided,

the presentation device is provided with:

an estimation unit that estimates a behavior of a vehicle;

an irradiation unit that irradiates the projection pattern toward the ground around the vehicle; and

a control unit that controls the irradiation unit so that the projection pattern is irradiated in accordance with the behavior of the vehicle estimated by the estimation unit.

2. The prompting device of claim 1,

the estimation unit estimates an abnormal behavior of the vehicle based on detection information acquired from an internal sensor that detects a behavior of the vehicle.

3. The prompting device of claim 1,

the estimation unit estimates an abnormal behavior of the vehicle based on detection information acquired from an external sensor that detects a situation around the vehicle.

4. The prompting device of claim 1,

the control unit controls the irradiation unit so that the display form of the projection pattern changes in accordance with the tendency when the abnormal behavior of the vehicle estimated by the estimation unit tends to deteriorate.

5. The prompting device of claim 1,

the control unit specifies a range around the vehicle that is expected to be affected by the abnormal behavior of the vehicle estimated by the estimation unit, and controls the irradiation unit so as to irradiate the projection pattern onto the ground in the specified range around the vehicle.

6. The prompting device of claim 5,

the control unit further divides a range around the vehicle, which is expected to be affected by the abnormal behavior of the vehicle, into a plurality of ranges according to a distance from the vehicle, and controls the irradiation unit so that a display form of the projection pattern continuously changes in each of the plurality of ranges.

7. A warning unit as claimed in any one of claims 4 to 6,

the projection pattern is displayed in at least one of a blinking speed, color, brightness, chroma, intensity, shape, size, character information addition, and graphic information addition.

8. The prompting device of claim 1,

the control unit causes the irradiation unit to irradiate the projection pattern when the estimation unit does not allow the remote control terminal to control the vehicle.

9. The prompting device of claim 1,

the control unit causes the irradiation unit to irradiate a projection pattern corresponding to a state in which the vehicle estimated by the estimation unit cannot travel in any direction.

Technical Field

The present invention relates to a presentation device that irradiates a projection pattern corresponding to a behavior of a vehicle.

Background

Conventionally, there is known a technique of outputting a simulated traveling sound or a warning sound to the outside of a vehicle to notify a pedestrian of the approach of the vehicle. However, when the simulated running sound or the warning sound is output, silence outside the vehicle is impaired, and therefore, the pedestrian to be warned becomes a noise to the outside.

On the other hand, a technique of presenting the behavior of a moving object without using a simulated traveling sound or a warning sound has also been proposed. For example, an autonomous moving apparatus described in patent document 1 includes a monitor that displays a current focus point forward in a traveling direction. The person who is located on the moving path of the autonomous moving apparatus can recognize the moving direction of the autonomous moving apparatus based on the focus displayed on the display unit.

Disclosure of Invention

Problems to be solved by the invention

In the conventional technology represented by patent document 1, there is a problem that the behavior of the vehicle cannot be grasped when people located around the vehicle are not looking at the display unit of the vehicle.

Further, if the warning sound is used, the behavior of the vehicle can be grasped even if people around the vehicle are not looking at the vehicle, but as described above, the warning sound is a noise to the outside of the warning target person.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a presentation device that does not generate noise and can grasp the behavior of a vehicle even if the vehicle is not watched.

Means for solving the problems

The presentation device of the present invention includes: an estimation unit that estimates a behavior of a vehicle; an irradiation unit that irradiates the projection pattern toward the ground around the vehicle; and a control unit that controls the irradiation unit so as to irradiate the projection pattern corresponding to the behavior of the vehicle estimated by the estimation unit.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, since the projection pattern corresponding to the behavior of the vehicle is irradiated onto the ground around the vehicle, noise is not generated, and the behavior of the vehicle can be grasped without looking at the vehicle.
