System and method for providing weather warnings and alerts
First Claim
1. A method for receiving weather data at a vehicle, comprising:
- receiving a first broadcast signal at the vehicle, the first broadcast signal containing weather data referenced to a plurality of cells arranged in a grid corresponding to a geographic map, the weather data including one or more assigned warning numbers linking the plurality of cells to at least one weather warning;
receiving a second broadcast signal at the vehicle, the second broadcast signal containing weather warning information, the weather warning information including the weather warning associated with said one or more assigned warning numbers;
determining a current location, speed, and direction of the vehicle;
using the current location, speed, and direction of the vehicle to calculate a future location of the vehicle, the future location of the vehicle being different from the current location of the vehicle;
correlating the future location of the vehicle to at least one of the plurality of cells;
identifying a portion of the weather data referenced to said at least one of the plurality of cells;
filtering the weather data to yield at least filtered data referenced to said at least one of the plurality of cells correlated to the future location of the vehicle; and
formatting the filtered data for display to vehicle occupants.

Abstract
A method is provided for providing weather data to a vehicle comprising the steps of: (a) receiving a broadcast signal containing weather data referenced to a plurality of cells arranged in a grid corresponding to a geographic map; (b) determining the present location, speed, and direction of the vehicle; (c) calculating a geographic region for which the weather data will affect the vehicle user based upon the current location, speed, and direction of the vehicle; (d) filtering the weather data to yield filtered data comprising at least one of the plurality of cells correlated to the previously calculated geographic region; and (e) formatting the filtered data for display to vehicle occupants.

11. A system for receiving weather data at a vehicle, comprising:
-
a telematics unit in the vehicle equipped to receive weather data over a broadcast network such that the weather data is referenced to a plurality of cells arranged in a grid corresponding to a geographic map, the weather data including one or more assigned warning numbers linking the plurality of cells to at least one weather warning; wherein the telematics unit is further adapted to receive weather warning information over the broadcast network, the weather warning information including the weather warning associated with said one or more assigned warning numbers; and a navigation system in electrical communication with the telematics unit for reception of the weather data and further comprising a display equipped to present the weather data to a user, a Global Positioning System antenna equipped to determine the vehicle location, a speed sensor equipped to determine the vehicle speed, and a yaw-rate sensor equipped to determine the vehicle direction; wherein the navigation system is adapted to calculate a future location of the vehicle using the current location, speed, and direction of the vehicle, the future location being different from the current location, and correlate the calculated future location of the vehicle to at least one of the plurality of cells; and wherein at least one of the telematics unit and the navigation system is adapted to identify a portion of the weather data referenced to said at least one of the plurality of cells and to filter the weather data prior to displaying to the user the weather data referenced to said at least one of the plurality of cells correlated to the future location of the vehicle. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method for providing weather warnings at a vehicle, comprising:
-
receiving a first broadcast signal containing weather warning mesh data, the weather warning mesh data including a plurality of cells associated with one or more assigned numbers corresponding to at least one weather warning; receiving a second broadcast signal containing weather warning information, the weather warning information including the weather warning associated with said one or more assigned warning numbers; linking the weather warning to one or more of the plurality of cells contained in the weather warning mesh data using the assigned warning numbers; using at least current location, speed, and direction information to calculate a future location of the vehicle; determining whether the future location of the vehicle is in or near said one or more of the plurality of cells contained in the weather warning mesh data linked to the weather warning; and displaying the weather warning to the vehicle user if the future location of the vehicle is in or near said one or more of the plurality of cells contained in the weather warning mesh data linked to the weather warning. - View Dependent Claims (31, 32, 33, 34, 35)
