1. A computer-implemented method of determining travel directions for a vehicle comprising:
- receiving, at a navigation computer, input representing vehicle coordinates and speed of a vehicle;
calculating, via the navigation computer, how far the vehicle is likely to travel within a predetermined time span, representing an estimated route calculation and transmission time, based on the vehicle speed;
determining where the vehicle is located on a map based on the coordinates;
determining possible location points to which the vehicle can travel on the map within the predetermined time span, based on the likely distance of travel;
determining a route of travel to a destination based on the coordinates of the vehicle;
determining one or more alternate routes of travel to the destination from at least one of the possible location points; and
transmitting to the vehicle a preferred route of travel and at least one alternate route of travel.

Abstract
A vehicle based computing system processor is operable to receive the coordinates from a GPS and transmit the coordinates to a remote network. The processor is operable to receive map data pertaining to a route to be traveled by the vehicle, including a recommended starting road. The processor is able to audibly announce the recommended starting road name on which the vehicle is not presently traveling and to determine if the vehicle has reached that road. The processor is operable to output at least initial instructions for the route to be traveled.

1. A computer-implemented method of determining travel directions for a vehicle comprising:
-
receiving, at a navigation computer, input representing vehicle coordinates and speed of a vehicle; calculating, via the navigation computer, how far the vehicle is likely to travel within a predetermined time span, representing an estimated route calculation and transmission time, based on the vehicle speed; determining where the vehicle is located on a map based on the coordinates; determining possible location points to which the vehicle can travel on the map within the predetermined time span, based on the likely distance of travel; determining a route of travel to a destination based on the coordinates of the vehicle; determining one or more alternate routes of travel to the destination from at least one of the possible location points; and transmitting to the vehicle a preferred route of travel and at least one alternate route of travel. - View Dependent Claims (2, 3, 4, 5)

6. A non-transitory computer readable storage medium storing a plurality of computer instructions, that, when executed, cause a computing system to perform the steps:
- receive input corresponding to coordinates and speed of a vehicle;
calculate how far the vehicle is likely to travel within a predetermined time span, representing an estimated route calculation and transmission time, based on at least the received speed input;
determine where the vehicle is located on a map based on the coordinates;
determine possible location points to which the vehicle can travel on the map within the predetermined time span, based on the possible distance of travel;
determine a preferred route of travel to a destination based on the coordinates of the vehicle;
determine one or more alternate routes of travel to the destination from at least one of the possible location points; and
transmit travel routes to the vehicle including at least the preferred route of travel and one alternate route of travel. - View Dependent Claims (7, 8, 9, 10)
