Abstract

A server device includes: a server communication unit configured to communicate with a vehicle, and receive fallen object avoidance information from the vehicle, the fallen object avoidance information including position information on a fallen object and information indicating whether an avoidance operation was performed by the vehicle for the fallen object; and a server control unit configured to determine, for the same fallen object that is present at the same position, whether the same fallen object should be avoided based on the fallen object avoidance information, and notify a first following vehicle that the same fallen object should be avoided when the server control unit determines that the same fallen object should be avoided, the first following vehicle being a vehicle that is traveling within a predetermined range behind the same fallen object.

First claim

What is claimed is:

1. A server device comprising,
a server communication unit configured to:
communicate with a vehicle, and
receive fallen object avoidance information from the vehicle, the fallen object avoidance information including position information on a fallen object and information indicating whether an avoidance operation was performed by the vehicle for the fallen object; and

a server control unit configured to:
determine, for a same fallen object that is present at a same position indicated by the position information, whether the same fallen object should be avoided based on the fallen object avoidance information, and
notify a first following vehicle that the same fallen object should be avoided when the server control unit determines that the same fallen object should be avoided, the first following vehicle being a vehicle that is traveling within a predetermined range behind the same fallen object, wherein

the server control unit is configured to determine that the same fallen object should be avoided when the server control unit determines that a ratio of a number of vehicles that performed the avoidance operation for the same fallen object to a total number of: i) vehicles that performed the avoidance operation for the same fallen object and ii) vehicles that did not perform the avoidance operation for the same fallen object, is equal to or greater than a predetermined value.

2. The server device according to claim 1 , wherein
the server control unit is configured to determine that a first fallen object and a second fallen object are the same fallen object when the first fallen object and the second fallen object are present within a predetermined distance and belong to when a same type of fallen objects.

3. The server device according to claim 1 , wherein
the fallen object avoidance information further includes a degree of the avoidance operation, and
the server control unit is configured to determine whether to avoid the fallen object based further on the degree.

4. The server device according to claim 1 , wherein whether the avoidance operation was performed is determined based on at least one of a steering operation and a braking operation.

5. A server device comprising:
a server communication unit configured to:
communicate with a vehicle, and
receive fallen object avoidance information from the vehicle, the fallen object avoidance information including position information on a fallen object and information indicating whether an avoidance operation was performed by the vehicle for the fallen object; and

a server control unit configured to:
determine, for a same fallen object that is present at a same position indicated by the position information, whether the same fallen object should be avoided based on the fallen object avoidance information,
notify a first following vehicle that the same fallen object should be avoided when the server control unit determines that the same fallen object should be avoided, the first following vehicle being a vehicle that is traveling within a predetermined range behind the same fallen object,
determine, for each of a plurality of adjacent lanes extending in a same direction, whether there is a fallen object that should be avoided on each of the plurality of adjacent lanes, and
notify a second following vehicle of a lane that is one of the plurality of adjacent lanes and that has a smallest number of fallen objects that should be avoided.

6. The server device according to claim 5 , wherein whether the avoidance operation was performed is determined based on at least one of a steering operation and a braking operation.

7. The server device according to claim 5 , wherein the server control unit is configured to determine that a first fallen object and a second fallen object are the same fallen object when the first fallen object and the second fallen object are present within a predetermined distance and belong to a same type of fallen objects.

8. The server device according to claim 5 , wherein
the fallen object avoidance information further includes a degree of the avoidance operation, and
the server control unit is configured to determine whether to avoid the fallen object based further on the degree.

9. A server device comprising:
a server communication unit configured to:
communicate with a vehicle, and
receive fallen object avoidance information from the vehicle, the fallen object avoidance information including position information on a fallen object and information indicating whether an avoidance operation was performed by the vehicle for the fallen object; and

a server control unit configured to:
determine, for a same fallen object that is present at a same position indicated by the position information, whether the same fallen object should be avoided based on the fallen object avoidance information,
notify a first following vehicle that the same fallen object should be avoided when the server control unit determines that the same fallen object should be avoided, the first following vehicle being a vehicle that is traveling within a predetermined range behind the same fallen object,
determine, after the server control unit determines that the same fallen object is a target fallen object that should be avoided, whether there is still the target fallen object by using an image that a second following vehicle has captured at the same position where the target fallen object was present, and
when it is determined that the target fallen object should no longer be avoided, send a notification to the first following vehicle that has been notified that the target fallen object should be avoided, the notification indicating that the target fallen object should no longer be avoided.

10. The server device according to claim 9 , wherein whether the avoidance operation was performed is determined based on at least one of a steering operation and a braking operation.

11. The server device according to claim 9 , wherein the server control unit is configured to determine that a first fallen object and a second fallen object are the same fallen object when the first fallen object and the second fallen object are present within a predetermined distance and belong to a same type of fallen objects.

12. The server device according to claim 9 , wherein
the fallen object avoidance information further includes a degree of the avoidance operation, and
the server control unit is configured to determine whether to avoid the fallen object based further on the degree.
