Method of triggering the transmission of data from a mobile asset
First Claim
1. A method for transmitting the location of a vehicle to a location remote from the vehicle comprising the steps of:
- a) determining a street attribute of the vehicle relative to a road network defined as a first location;
b) determining a change in the street attribute of the vehicle relative to the road network defined as a second location; and
c) automatically communicating the street attribute of the vehicle to the remote location based upon said change in street attribute including communicating the first location at a first interval frequency, and communicating the second location at a second interval frequency.

Abstract
A navigation system that uses a method for transmitting the location of a vehicle to a location remote from the vehicle is provided. The method includes determining a location of the vehicle relative to a road network defined as a first location, and determining a change in the location of the vehicle relative to the road network defined as a second location. The first location may be a first street while the second location is a second street different that the first street. The navigation system then communicates the location of the vehicle to the remote location when vehicle reaches the second location. In another aspect of the present invention, the method includes determining a location of the vehicle relative to a road network defined as a first location. A new location of the vehicle is determined relative to the road network and is defined as a second location. The first location of the vehicle is communicated to the remote location at a first frequency, and the second location of the vehicle is communicated to the remote location at a second frequency, which is different from the first frequency.

16. An apparatus for a navigation system for transmitting the location of a vehicle to a location remote from the vehicle, the apparatus comprising:
-
at least one position determining device for providing a vehicle location signal; a database having a map database with a road network; a processor interconnected to said at least one positioning device and said database for determining the location of the vehicle relative to said map; a transmitter for producing a transmission signal to the remote location having the location of the vehicle; a trigger device for triggering said transmission signal, wherein said triggering device determines a street attribute of the vehicle relative to said road network defined as a first location and determines a change in the street attribute of the vehicle relative to said road network defined as a second location, and said trigger device automatically commands said transmitter to produce said transmission signal based upon the change in location, wherein a third location is arranged between the first and second locations, and said trigger device communicates the first location at a first interval frequency, suppressing communication of the third location, and communicates the second location at a second interval frequency. - View Dependent Claims (17, 18, 19, 20, 21, 22)
