Abstract

An object identification apparatus includes: an identifier that identifies whether an object is a control target based on a result of comparison between reflection intensity of a detection wave and an identification threshold when the detection wave is received by the moving body; and a changer that changes identification sensitivity of the identifier according to positions of at least two points of the object when the detection wave is reflected at the at least two points and received by the moving body.

First claim

The invention claimed is:

1. An object identification apparatus, comprising:
a processor, which in operation, identifies whether an object is a control target based on a result of comparison between reflection intensity of a detection wave transmitted from a moving body to the object and an identification threshold when the detection wave is reflected by the object and received by the moving body, wherein,
the processor determines the object is a pillar object having a circumferential surface according to positions of at least two points of the object when the detection wave is reflected at the at least two points and received by the moving body, and changes an identification sensitivity in response to the object being the pillar object.

2. The object identification apparatus according to claim 1 , wherein, the processor:
determines a shape of the object based on a plurality of sets of coordinates of the object calculated by detecting a plurality of the detection waves respectively propagated in different routes, and
changes the identification sensitivity according to the plurality of sets of coordinates.

3. The object identification apparatus according to claim 1 , wherein the identification threshold is set according to the reflection intensity of the detection wave for a non-control target, which is not the control target, when distance between the at least two points is equal to or greater than a predetermined threshold.

4. The object identification apparatus according to claim 3 , wherein the non-control target is a lower object that is located on a road surface and has a height not causing collision with a body of the moving body.

5. The object identification apparatus according to claim 1 , wherein the processor changes the identification sensitivity by changing the identification threshold.

6. The object identification apparatus according to claim 1 , wherein the processor changes the identification sensitivity by changing the reflection intensity.

7. The object identification apparatus according to claim 1 , wherein the processor performs control of changing the identification sensitivity according to distance between the moving body and the object.

8. The object identification apparatus according to claim 2 , wherein the identification threshold is set according to the reflection intensity of the detection wave for a non-control target, which is not the control target, when distance between the at least two points is equal to or greater than a predetermined threshold.

9. The object identification apparatus according to claim 1 , wherein the identification threshold is set according to the reflection intensity of the detection wave for a non-control target, which is not the control target, when distance between the at least two points is equal to or greater than a predetermined threshold.

10. The object identification apparatus according to claim 8 , wherein the non-control target is a lower object that is located on a road surface and has a height not causing collision with a body of the moving body.

11. The object identification apparatus according to claim 9 , wherein the non-control target is a lower object that is located on a road surface and has a height not causing collision with a body of the moving body.

12. The object identification apparatus according to claim 2 , wherein the processor changes the identification sensitivity by changing the identification threshold.

13. The object identification apparatus according to claim 3 , wherein the processor changes the identification sensitivity by changing the identification threshold.

14. The object identification apparatus according to claim 4 , wherein the processor changes the identification sensitivity by changing the identification threshold.

15. The object identification apparatus according to claim 2 , wherein the processor changes the identification sensitivity by changing the reflection intensity.

16. A system, comprising:
a processor, which in operation, identifies whether an object is a control target based on a result of comparison between reflection intensity of a detection wave transmitted from a moving body to the object and an identification threshold when the detection wave is reflected by the object and received by the moving body, wherein,
the processor determines the object is a pillar object having a circumferential surface according to positions of at least two points of the object when the detection wave is reflected at the at least two points and received by the moving body, and changes an identification sensitivity in response to the object being the pillar object;

a wave transmission sensor, which in operation, transmits the detection wave; and
at least two wave reception sensors, which in operation, receive the detection wave.

17. An object identification method, comprising:
identifying whether an object is a control target based on a result of comparison between reflection intensity of a detection wave transmitted from a moving body to the object and an identification threshold when the detection wave is reflected by the object and received by the moving body, wherein
the identifying includes determining the object is a pillar object having a circumferential surface according to positions of at least two points of the object when the detection wave is reflected at the at least two points and received by the moving body, and changing an identification sensitivity in response to the object being the pillar object.
