Vehicular navigation system updating based on object presence
First Claim
1. A vehicular navigation system updating system for updating vehicular navigation systems in vehicles, comprising:
- at least one condition detector that automatically detects 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, said at least one condition detector being configured to detect 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, said at least one condition detector being situated on a vehicle;
a first communications system coupled to said at least one condition detector that wirelessly transmits a signal, data or information about the presence of the object or condition at the specific location automatically detected by said at least one condition detector, said first communications system being situated on the same vehicle as said at least one condition detector;
a second communications system that wirelessly receives transmission of the signal, data or information about the detected presence of the object or condition at the specific location from said first communications system; and
a processor coupled to said second communications system and situated at a site remote from said at least one condition detector and that is configured to generate an update for a map provided by vehicular navigation systems based on the detected presence of the object or condition at the specific location and direct communication of the generated map update to at least one vehicle in a vicinity of the specific location at which said at least one condition detector detected the presence of the object or condition,whereby the vehicular navigation system of the at least one vehicle uses the map with the map update to display or otherwise indicate the presence of the object or condition at the specific location.

Abstract
Vehicular navigation system updating system includes condition detectors that detect presence of an object or condition potentially interfering with movement of vehicles on a roadway, each condition detector being located on or alongside the roadway or in a vehicle. A signal, data or information about the detected presence of the object or condition is transmitted to a remote site at which a processor generates an update for a map based on the detected presence of the object or condition and directs communication of the map update to vehicles in a vicinity of a location at which the condition detector detected the presence of the object or condition. The vehicular navigation system of each vehicle uses the map with the map update to display or otherwise indicate the presence of the object or condition. Another map update is generated when the absence of the object or condition is determined.

10. A method for automatically conveying information about a roadway condition to vehicular navigation systems in vehicles, comprising:
-
identifying presence of an object or condition at a specific location using at least one condition detector located on or alongside a roadway, the presence of the object or condition at the specific location affecting movement of vehicles on the roadway, 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; and when the presence of an object or condition is identified, transmitting a signal, data or information about the presence of the object or condition at the specific location identified by the at least one condition detector to a remote site using a first communications system; generating, using a processor at the remote site, an update for a map provided by vehicular navigation systems based on the identified presence of the object or condition at the specific location; and transmitting, using a second communications system, the generated map update to at least one vehicle in a vicinity of the specific location at which the at least one condition detector identified the presence of the object or condition to cause a vehicular navigation system of the at least one 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. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
