1. A method for updating a remote geographic database at specified times, the method comprising:
- receiving sensor data indicative of a road object;
determining a geographic position associated with the road object;
performing, at a controller, a geographic comparison of the geographic position and the data indicative of the road object to data associated with the geographic position in a local database,wherein the geographic comparison is performed in response to a time comparison between a time since the sensor data was received and a predetermined time that is equal to or greater than an update interval that specifies how often updates are provided from the remote geographic database to the local database; and
sending an update to the remote geographic database in response to the time comparison and the geographic comparison, the update including the data indicative of the road object.

Abstract
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.

11. An apparatus for sending updates to a remote database at predetermined times, the apparatus comprising:
-
a sensor configured to receive sensor data indicative of a road object; a position detector configured to determine a geographic position associated with the road object; a timer configured to determine when a predetermined time has elapsed since the sensor data was received, wherein the predetermined time is equal to or greater than an update interval that specifies how often updates are provided from the remote database to a local database; and a controller configured to compare the geographic position associated with the road object to the local database, and generate an update message for the remote database in response to the predetermined time elapsing. - View Dependent Claims (12, 13, 14)

15. A method for geographic database updates, the method comprising:
-
receiving, from a memory, sensor data indicative of a road object; determining a geographic position associated with the road object; identifying a confidence value in a local database; comparing the confidence value to a confidence threshold; and discarding the sensor data indicative of the road object from the memory in response to the confidence value exceeding the confidence threshold. - View Dependent Claims (16, 17, 18, 19)

20. An apparatus for a vehicle traveling on a roadway, the apparatus comprising:
-
a sensor configured to receive sensor data indicative of a road object of the roadway; a memory configured to store the sensor data; a position detector configured to determine a geographic position associated with the road object; a vehicle database including a confidence level associated with the road object; a controller configured to compare the geographic position associated with the road object to the vehicle database and discard, from memory, the data indicative of the road object in response to the confidence level; and a timer configured to determine when a predetermined time has elapsed since the sensor data was received, wherein the predetermined time is equal to or greater than an update interval that specifies how often updates are provided from a remote database to the vehicle database, wherein the controller is configured to generate an update message for the remote database in response to the predetermined time elapsing.
