1. A method, comprising the steps of:
- receiving, at a processing platform of a vehicle navigation system, a request for a route plan from a vehicle operably connected to the vehicle navigation system, wherein the processing platform has a processor and a memory;
identifying, at the processing platform, a plurality of candidate route segments for the vehicle;
obtaining, at the processing platform, speed metrics associated with the plurality of candidate route segments corresponding to a first traffic state and a second traffic state, wherein the speed metrics include speed limits and projected transit times associated with the plurality of candidate route segments which are stored in a database, and wherein the second traffic state is a prospective state occurring after the first traffic state;
identifying, at the processing platform, the route plan for the vehicle, the route plan defining a route from a first location to a second location comprising one or more selected segments of the plurality of candidate route segments, the route plan further defining a schedule for navigating the selected segments, wherein the schedule provides for navigating at least a portion of the selected segments in the second traffic state based on time efficiencies realized from the speed metrics of the second traffic state relative to the first traffic state;
identifying, at the processing platform, a route segment that identifies a recharging station for the vehicle within a navigable range of the vehicle;
allocating, at the processing platform, time in the route plan for recharging the vehicle at the recharging station; and
communicating, at the processing platform, the route plan to the vehicle.

Abstract
An improved vehicle navigation system and method provides a route plan or alternative route based at least in part on evolved state information (e.g., a second traffic state, occurring some time after a first traffic state) from which time-efficiencies may be realized relative to navigation in a previous traffic state. Optionally, the route plan may identify an intermediate destination (e.g., such as a refueling or recharging station) and the schedule may allocate time for customer activities at the intermediate destination.

9. An apparatus for a vehicle navigation system comprising:
-
one or more processing devices; and a non-transitory computer readable storage device with computer executable instructions stored thereon that, when executed by the one or more processing devices, causes the one or more processing devices to; receive a request for a route plan from a vehicle operably connected to the vehicle navigation system; identify a plurality of candidate route segments for the vehicle; obtain speed metrics associated with the plurality of candidate route segments corresponding to a first traffic state and a second traffic state, wherein the speed metrics are stored and include speed limits and projected transit times associated with the plurality of candidate route segments, and wherein the second traffic state is a prospective state occurring after the first traffic state; identify the route plan for the vehicle, the route plan defining a route from a first location to a second location comprising one or more selected segments of the plurality of candidate route segments, the route plan further defining a schedule for navigating the selected segments, wherein the schedule provides for navigating at least a portion of the selected segments in the second traffic state based on time efficiencies realized from the speed metrics of the second traffic state relative to the first traffic state; identify a route segment that identifies a recharging station for the vehicle within a navigable range of the vehicle; allocate time in the route plan for recharging the vehicle at the recharging station; and communicate the route plan to the vehicle. - View Dependent Claims (10, 11, 12)
