Abstract

A vehicle includes a communication interface, a memory device, and a processing device. The communication interface is configured to communicate over a communication network. The memory device is configured to store a connectivity map associated with a geographic area. The connectivity map defines a communication quality at a plurality of locations in the geographic area. The processing device is configured to initiate a remote data transfer over the communication network in accordance with the connectivity map.

Claims

1. A vehicle system comprising:

a communication interface configured to communicate over a communication network;

a memory device configured to store a connectivity map associated with a geographic area, the connectivity map defining a communication quality at a plurality of locations in the geographic area; and

a processing device programmed to initiate a remote data transfer over the communication network in accordance with the connectivity map, determine from the connectivity map whether a vehicle is heading toward a location with poor communication quality and determine whether there is time to complete the remote data transfer before reaching the location with poor communication quality, and

if the remote data transfer has already begun and the remote data transfer cannot be completed before reaching the location with poor communication quality, the processing device is programmed to pause a pending remote data transfer prior to the vehicle arriving at the location with poor communication quality, and

if the data transfer has not yet begun and the remote data transfer cannot be completed before reaching the location with poor communication quality, the processing device is programmed to wait to initiate the remote data transfer until after the vehicle is through the location with poor communication quality.

2. The vehicle system of claim 1, wherein, after pausing the pending remote data transfer, the processing device is programmed to compare the communication quality at a present location to a threshold.

3. The vehicle system of claim 2, wherein the processing device is programmed to resume the paused remote data transfer if the communication quality at the present location exceeds the threshold.

4. The vehicle system of claim 1, wherein the remote data transfer includes uploading data to a remote server.

5. The vehicle system of claim 1, wherein the remote data transfer includes downloading data from a remote server.

6. The vehicle system of claim 1, wherein the processing device is configured to compare an observed data transfer quality to at least one communication quality defined by the connectivity map, and wherein the connectivity map is updated if the observed data transfer quality is different from the communication quality defined by the connectivity map.

7. The vehicle system of claim 6, wherein the processing device is configured to determine the communication quality at a plurality of locations and generate the connectivity map by associating the determined communication quality to at least one of the plurality of locations.

8. The vehicle system of claim 1, wherein the connectivity map is received at the communication interface in accordance with a vehicle-to-vehicle communication protocol.

9. The vehicle system of claim 1, wherein the connectivity map is received at the communication interface from a remote server.

10. A vehicle system comprising:

a processing device programmed to initiate a remote data transfer over a communication network in accordance with a connectivity map, the connectivity map defining a communication quality at a plurality of locations within a geographic area,

wherein the processing device is programmed to determine from the connectivity map whether a vehicle is heading toward a location with poor communication quality and determine whether there is time to complete the remote data transfer before reaching the location with poor communication quality, and if the remote data transfer cannot be completed before reaching the location with poor communication quality, the processing device is programmed to;

pause a pending remote data transfer prior to the vehicle arriving at the location with poor communication quality, and

wait to initiate a new remote data transfer until after the vehicle is through the location with the poor communication quality.

11. The vehicle system of claim 10, wherein, after pausing the pending remote data transfer, the processing device is programmed to compare the communication quality at a present location to a threshold.

12. The vehicle system of claim 11, wherein the processing device is programmed to resume the paused remote data transfer if the communication quality at the present location exceeds the threshold.

13. The vehicle system of claim 10, wherein the remote data transfer includes uploading data to a remote server.

14. The vehicle system of claim 10, wherein the remote data transfer includes downloading data from a remote server.

15. The vehicle system of claim 10, wherein the processing device is configured to compare an observed data transfer quality to at least one communication quality defined by the connectivity map, and wherein the connectivity map is updated if the observed data transfer quality is different from the communication quality defined by the connectivity map.

16. The vehicle system of claim 15, wherein the processing device is configured to determine the communication quality at a plurality of locations and generate the connectivity map by associating the determined communication quality to at least one of the plurality of locations.

17. The vehicle system of claim 10, wherein the connectivity map is received in accordance with a vehicle-to-vehicle communication protocol.

18. The vehicle system of claim 10, wherein the connectivity map is received from a remote server.

19. A method comprising:

accessing a connectivity map defining a communication quality at a plurality of locations within a geographic area;

comparing the communication quality at one of the plurality of locations to a threshold;

initiating a remote data transfer over a communication network if the communication quality at one of the plurality of locations exceeds the threshold;

determining from the connectivity map whether a vehicle is heading toward a location with poor communication quality;

determining whether there is time to complete the remote data transfer before the vehicle reaches the location with poor communication quality; and

if the remote data transfer cannot be completed before reaching the location with poor communication quality;

for a pending remote data transfer;

pausing the pending remote data transfer prior to the vehicle arriving at the location with poor communication quality;

determining a communication quality at a present location; and

resuming the pending remote data transfer if the communication quality at the present location exceeds the threshold; and

for a new remote data transfer;

waiting to initiate the new remote data transfer until the vehicle is through the location with poor communication quality.

20. The method of claim 19, wherein the remote data transfer includes at least one of uploading data to a remote server and downloading data from the remote server.
