Abstract

Methods, systems, and apparatuses for adaptive download of map information are presented which include obtaining a route from a start location to a destination location for a vehicle, acquiring projected environmental information associated with a first portion in the route the vehicle is expected to traverse, acquiring projected network availability information associated with a second portion in the route the vehicle is expected to traverse; and determining whether to download map information associated with the first portion of the route based on (1) the projected environmental information and (2) the projected network availability information.

Claims

1. A method, comprising:

obtaining, by a processor of a vehicle, a route from a start location to a destination location for the vehicle;

acquiring, by the processor, projected environmental information associated with a first portion in the route the vehicle is expected to traverse, the projected environmental information indicating low visibility in the first portion in the route;

acquiring, by the processor, projected network availability information associated with a second portion in the route the vehicle is expected to traverse; and

determining, by the processor, whether to download map information associated with the first portion of the route based on (1) the projected environmental information and (2) the projected network availability information.

2. The method of claim 1, wherein the second portion precedes the first portion in the route toward the destination location.

3. The method of claim 1, wherein the second portion and the first portion are substantially co-located on the route.

4. The method of claim 1, determining whether to download map information further comprising:

comparing the map information with pre-stored information in a data storage unit of the vehicle; and

determining to not download portions of the map information pre-stored in a data storage unit of the vehicle.

5. The method of claim 1, determining whether to download map information further comprising:

determining a time to download the map information prior to a projected arrival of the vehicle at the first portion, wherein the time to download is determined based on network availability in at least one of a present location or future projected location of the vehicle along the route.

6. The method of claim 1, determining whether to download map information further comprising:

determining a time to download the map information prior to a projected arrival of the vehicle at the first portion, wherein the time to download is determined based on available storage space in a data storage unit of the vehicle.

7. The method of claim 1, further comprising:

downloading the map information based on the determining.

8. The method of claim 1, wherein the environmental information is acquired based on information received from at least one sensor housed within the vehicle.

9. The method of claim 1, wherein the environmental information is acquired based on information received from at least one sensor housed within at least one other vehicle.

10. The method of claim 1, wherein the map information is used to autonomously navigate the vehicle.

11. An apparatus comprising:

a processor configured to obtain a route from a start location to a destination location for a vehicle, the processor further configured to determine whether to download map information associated with a first portion of the route based on (1) acquired projected environmental information associated with the first portion in the route the vehicle is expected to traverse, the projected environmental information indicating low visibility in the first portion in the route, and (2) acquired projected network availability information associated with a second portion in the route the vehicle is expected to traverse; and

a data storage unit configured to communicate with the processor and to store map information.

12. The apparatus of claim 11, wherein the data storage unit is housed within the vehicle and configured to store downloaded map information.

13. The apparatus of claim 12, the processor is further configured to compare the map information with pre-stored information in a data storage unit of the vehicle;

and to not download portions of the map information pre-stored in a data storage unit of the vehicle.

14. The apparatus of claim 11, the processor is further configured to determine a time to download the map information prior to a projected arrival of the vehicle at the first portion,

wherein the time to download is based on network availability in at least one of a present location and future projected location of the vehicle along the route.

15. The apparatus of claim 12, the processor is further configured to determine a time to download the map information prior to a projected arrival of the vehicle at the first portion,

wherein the time to download is based on available storage space in a data storage unit of the vehicle.

16. The apparatus of claim 11, further comprising:

a communication device configured to download the map information.

17. The apparatus of claim 11, further comprising at least one sensor housed within the vehicle configured to obtain the environmental information for the processor.

18. The apparatus of claim 11, the processor further configured to navigate the vehicle based on the downloaded map information.

19. An apparatus comprising:

means for obtaining a route from a start location to a destination location for a vehicle;

means for acquiring projected environmental information associated with a first portion in the route the vehicle is expected to traverse, the projected environmental information indicating low visibility in the first portion in the route;

means for acquiring projected network availability information associated with a second portion in the route the vehicle is expected to traverse; and

means for determining whether to download map information associated with the first portion of the route based on (1) the projected environmental information and (2) the projected network availability information.

20. The apparatus of claim 19, wherein the means for determining whether to download map information further comprising:

means for determining a time to download the map information prior to a projected arrival of the vehicle at the first portion, wherein the time to download is determined based on (a) network availability in at least one of a present location or future projected location of the vehicle along the route, or (b) available storage space in a data storage unit of the vehicle; and

means for comparing the map information with pre-stored information in a data storage unit of the vehicle, and not downloading portions of the map information pre-stored in a data storage unit of the vehicle.
