Abstract

A moving object trajectory estimating device has: a surrounding information acquisition part that acquires information on surroundings of a moving object; a trajectory estimating part that specifies another moving object around the moving object based on the acquired surrounding information and estimates a trajectory of the specified moving object; and a recognition information acquisition part that acquires recognition information on a recognizable area of the specified moving object, and the trajectory estimating part estimates a trajectory of the specified moving object, based on the acquired recognition information of the specified moving object.

Claims

1. A moving object trajectory estimating device, comprising:

a surrounding information acquisition sensor that acquires information on surroundings of a moving object;

a trajectory estimating electronic control unit that specifies another moving object around the moving object based on the surrounding information acquired by the surrounding information acquisition sensor; and

a recognition information acquisition electronic control unit that acquires recognition information on a recognizable area for the specified moving object based on at least one of (i) information which is received from the specified moving object through communication with the specified moving object, or which is stored in a database in the moving object, and (ii) shape information of a structure around a road,

wherein the trajectory estimating electronic control unit estimates a trajectory of the specified moving object based on the recognition information on the recognizable area of the specified moving object acquired by the recognition information acquisition electronic control unit.

2. The moving object trajectory estimating device according to claim 1, wherein the recognition information acquisition electronic control unit acquires, from the specified moving object, information that includes the recognizable area.

3. The moving object trajectory estimating device according to claim 2, wherein the recognition information acquisition electronic control unit acquires information that includes the recognizable area for the specified moving object, based on individual information on the specified moving object.

4. The moving object trajectory estimating device according to claim 3, wherein the moving object is a vehicle.

5. The moving object trajectory estimating device according to claim 4, wherein the specified moving object is a vehicle.

6. The moving object trajectory estimating device according to claim 5, wherein the recognizable area of the specified moving object is a visible area of the specified moving object.

7. The moving object trajectory estimating device according to claim 6, wherein the individual information on the specified moving object is individual blind spot information on the specified moving object.

8. The moving object trajectory estimating device according to claim 1, wherein the shape information of the structure around the road includes information on a height of the structure around the road.
