VEHICULAR NAVIGATION SYSTEM UPDATING BASED ON OBJECT PRESENCE/ABSENCE
First Claim
1. A processing arrangement for managing temporary updates to a map for use by vehicular navigation systems in a plurality of vehicles, comprising:
- a communications system at a remote site that is configured to receive wireless communications from each of the vehicles that includes information about presence of an object or condition at a specific location automatically identified at the specific location without requiring manual entry of data about the object or condition at the specific location, the presence of the object or condition at the specific location affecting movement of vehicles on a roadway; and
a processor coupled to said communications system and configured to generate an update for a map for use by the vehicular navigation systems based on the identified object or condition at the specific location included in the communications received by said communications system;
said communications system being configured to transmit the generated map update to any vehicle in a vicinity of the specific location to cause the vehicular navigation system of that vehicle to use a map with the generated map update to display or otherwise indicate the presence of the object or condition at the specific location,said processor being further configured to;
process wireless communications received from each of the vehicles using said communications system including information that the object or condition whose presence was previously detected at the specific location is absent at the specific location at a subsequent time after generation of the map update relating to the presence of that object or condition at the specific location,generate another update for a map for use by the vehicular navigation systems based on the absence of the object or condition at the specific location provided during processing of the wireless communications received from each of the vehicles using said communications system; and
direct transmission of the another map update using said communications system to any vehicle in a vicinity of the specific location to cause the vehicular navigation system of the vehicles to use a map with the another map update to avoid display or indication of the presence of the object or condition at the specific location.

Abstract
Processing arrangement for managing temporary updates to a map for use by vehicular navigation systems in vehicles in which a communications system at a remote site receives wireless communications from each vehicle including information about presence of an object or condition at a specific location automatically identified at the specific location without requiring manual entry of data about the object or condition at the specific location and that affects movement of vehicles on a roadway. A processor generates a map update for use by vehicular navigation systems based on the identified object or condition at the specific location which is transmitted to any vehicle in a vicinity of the specific location to cause the vehicular navigation system of that vehicle to use a map with the generated map update to display or otherwise indicate the presence of the object or condition at the specific location.

5. A multi-vehicle method for causing temporary updates to a map for use by a vehicular navigation system in each vehicle, comprising:
-
identifying presence of an object or condition at a specific location and for which presence of the object or condition at the specific location affects movement of vehicles on a roadway using at least one condition detector located on at least one of the vehicles or infrastructure, the at least one condition detector being configured to identify the presence of the object or condition at the specific location without requiring manual entry of data about the object or condition at the specific location; when the presence of an object or condition is identified by the at least one condition detector, wirelessly communicating the presence of the object or condition at the specific location automatically identified by the at least one condition detector to a remote site using a first communications system coupled to the at least one condition detector; generating, using a processor at the remote site, an update for a map for use by the vehicular navigation systems based on the identified object or condition at the specific location; transmitting, using a second communications system associated with the remote site, the generated map update to any vehicle in a vicinity of the specific location at which the at least one condition detector detected the presence of the object or condition to cause the vehicular navigation system of that vehicle to use a map with the generated map update to display or otherwise indicate the presence of the object or condition at the specific location; determining whether the object or condition whose presence was detected by the at least one condition detector at the specific location is still present at that location or is absent at the specific location at a subsequent time after generation of the map update relating to the presence of that object or condition using an assessment system in any of the vehicles passing by that location or infrastructure capable of obtaining information about that location, and when the assessment system determines that the object or condition is absent at the specific location, communicating the absence of the object or condition at the specific location to the remote site using a third communications system; generating, using the processor at the remote site, another update for the map for use by the vehicular navigation systems based on the absence of the object or condition at the specific location; transmitting, using the second communications system associated with the remote site, the another update to vehicles in that vicinity to cause the vehicular navigation system of the vehicles to use a map with the another map update to avoid display or indication of the presence of the object or condition at the specific location. - View Dependent Claims (6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
