Title: MAP UPDATES FROM A CONNECTED VEHICLE FLEET
Abstract: [0001]    A road furniture item or another type of road object is detected by at least one sensor. An associated geographic position associated with the road furniture item or road object is determined. After a predetermined time is reached, the geographic position is compared to a local database. A remote database is updated after the predetermined time is reached and according to the comparison with the local database. In some examples, the data indicative of the road furniture item or the road object is deleted based on a confidence level in the local database.

Claims: number: 1
text: A method for updating a remote geographic database at specified times, the method comprising:
number: 2
text: The method of claim 1, wherein the update is sent to the remote geographic database in response to the road furniture item being absent from the local database.
number: 3
text: The method of claim 2, wherein the update is sent to the remote geographic database in response reaching the predetermined time, wherein the predetermined time is based on an update schedule between the remote geographic database and the local database.
number: 4
text: The method of claim 1, wherein the road furniture includes a road sign or a traffic light.
number: 5
text: The method of claim 1, further comprising:
number: 6
text: The method of claim 5, wherein the sensor data indicative of the road furniture item is discarded when the second comparison indicates the local database already includes the road furniture item.
number: 7
text: The method of claim 1, further comprising:
number: 8
text: The method of claim 7, wherein the update is sent to the remote geographic database in response to confidence value being less than the confidence threshold.
number: 9
text: The method of claim 8, further comprising:
number: 10
text: The method of claim 1, wherein the sensor data indicates an absence of a road furniture item listed in the local database.
number: 11
text: An apparatus for sending updates to a remote database at predetermined times, the apparatus comprising:
number: 12
text: The apparatus of claim 11, further comprising:
number: 13
text: The apparatus of claim 11, wherein the update message is generated is response to the road object being absent from the local database.
number: 14
text: The apparatus of claim 11, wherein the update message is generated is response to a confidence value in the local database for the road object.
number: 15
text: A method for geographic database updates, the method comprising:
