Abstract

A vehicle determines that a stop is upcoming along a route and determines that the upcoming stop will place the vehicle within range of a wireless transceiver. The vehicle approximates a predicted transfer rate of the wireless transceiver and determines if data onboard the first vehicle is to be uploaded, based on at least a size of the data, a priority assigned to the data and the predicted transfer rate. Additionally, the vehicle determines a predicted duration of communication between the vehicle and the transceiver based on the route and the upcoming stop, allowing the vehicle to determine a first predicted amount of data able to be transferred. The vehicle designates first data for upload, based on the first data having a size that is below the first predicted amount and begins transferring the designated data responsive to establishing communication with the wireless transceiver.

First claim

What is claimed is:

1. A system comprising:
a processor configured to:
determine that a stop is upcoming along a route of a first vehicle;
determine that the upcoming stop will place the first vehicle within range of a wireless transceiver;
approximate a predicted transfer rate of the wireless transceiver;
determine if data onboard the first vehicle is to be uploaded, based on at least a size of the data, a priority assigned to the data and the predicted transfer rate;
determine a predicted duration of communication between the first vehicle and the transceiver based on the route and the upcoming stop;
determine a first predicted amount of data able to be transferred based on the predicted duration and the predicted transfer rate;
responsive to determining that data is to be uploaded, designate first data for upload based on the first data having a size that is below the first predicted amount; and
responsive to the first vehicle establishing communication with the wireless transceiver, begin transferring the designated data.

2. The system of claim 1 , wherein the processor is configured to determine that the stop is upcoming based on data wirelessly provided by a signal, instructing the stop.

3. The system of claim 1 , wherein the processor is configured to determine that the stop is upcoming based on previously stored timing data for a signal, instructing the stop, and based on a present state of the signal provided by a second vehicle reporting the present state.

4. The system of claim 1 , wherein the processor is configured to approximate the predicted transfer rate based on a second vehicle, connected to the transceiver, reporting a present transfer rate.

5. The system of claim 1 , wherein the expected duration of communication is based on at least a predicted duration of the stop and a predicted impact of traffic on travel of the first vehicle while the first vehicle is in communication with the transceiver.

6. The system of claim 1 , wherein the designated first data is designated from a plurality of possible data candidates, each having a size below the first predicted amount, based additionally on the first data having a priority equal to or higher than a highest priority assigned to other of the possible data candidates.

7. The system of claim 1 , wherein the processor is further configured to:
determine, after establishing communication with the wireless transceiver, a new predicted amount of data less than the first amount and less than the size of the first data, and responsively designate new data for upload based on the new data having a size that is below the new predicted amount of data.

8. The system of claim 1 , wherein the processor is further configured to:
determine, after establishing communication with the wireless transceiver, a new predicted amount of data less than the first amount and less than the size of the first data, and responsively wirelessly transfer at least a portion of the first data to a second vehicle in communication range of the first vehicle.

9. A first vehicle comprising:
a processor configured to:
wirelessly receive route data from a second vehicle indicating both a shared portion of an upcoming route of the first vehicle and a deviance, after the shared portion, from the upcoming route;
determine, based on the received route data, that the deviance will bring the second vehicle within communicable range of first known wireless transceiver sooner than the first vehicle will come within communicable range of a second known wireless transceiver; and
wirelessly transfer data, designated for upload, from the first vehicle to the second vehicle responsive to the determination.

10. The first vehicle of claim 9 , wherein the processor is further configured to:
further condition the wireless transfer of data based on a second determination that the shared portion of the upcoming route will keep the first and second vehicles in communicable proximity for sufficient duration to complete wireless transfer of the data.

11. The first vehicle of claim 10 , wherein the processor is further configured to:
coordinate with the second vehicle, responsive to the second determination, to control the first vehicle to remain in the communicable proximity over travel along the shared portion, at least until the wireless transfer of the data is complete or the second vehicle reaches the deviance.

12. The first vehicle of claim 9 , wherein the processor is further configured to:
further condition the wireless transfer of data based on receipt of confirmation from the second vehicle that the second vehicle will accept the data.

13. The first vehicle of claim 9 , wherein the processor is further configured to:
receive notification from a remote server that the second vehicle successfully uploaded the data and responsively delete the data from a memory of the first vehicle.

14. A system comprising:
a processor configured to:
determine that a first vehicle includes first data designated for upload;
determine that a first and second vehicle will travel in communicable proximity to each other for at least a duration sufficient to wirelessly transfer the first data from the first vehicle to the second vehicle, based on route data of the first and second vehicles; and
determine that the second vehicle will travel within communicable range of first known wireless transceiver sooner than the first vehicle will come within communicable range of a second known wireless transceiver, based on the route data, and responsively instruct the first vehicle to transfer the first data to the second vehicle when the first vehicle is within communicable proximity to the second vehicle.

15. The system of claim 14 , wherein the processor is further configured to:
determine that the second vehicle will be able to complete upload of the data using the first known wireless transceiver; and
further condition instructing the first vehicle based on the determination that the second vehicle will be able to complete the upload.

16. The system of claim 15 , wherein the determination that the second vehicle will be able to complete upload is based at least in part on a size of the data and a projected transfer speed of the first wireless transceiver.

17. The system of claim 15 , wherein the determination that the second vehicle will be able to complete upload is based at least in part on a size of the data and a projected duration of communication between the second vehicle and the first wireless transceiver.

18. The system of claim 15 , wherein the determination that the second vehicle will be able to complete upload is based at least in part on a size of the data, a projected transfer speed of the first wireless transceiver, and a projected duration of communication between the second vehicle and the first wireless transceiver.

19. The system of claim 15 , wherein the processor is further configured to:
determine a predicted amount of data uploadable by the second vehicle using the first transceiver based at least in part on a size of the data, a projected transfer speed of the first wireless transceiver, and a projected duration of communication between the second vehicle and the first wireless transceiver; and
instruct the first vehicle transfer additional data to the second vehicle, responsive to the first data being smaller than the predicted amount, the first vehicle including second data designated for upload, and the duration additionally being sufficient to wirelessly transfer the second data from the first v
