Abstract

A vehicle information gathering system comprises an onboard communication device, an onboard storage device and an onboard controller. The onboard communication device communicates with external data sources. The onboard storage device stores a data set comprising at least one data subset reference. The onboard controller automatically determines an availability of each of the external data sources, assigns a respective communication priority to each data subset reference based on the availability of each of the external data sources and at least one priority criteria, assigns at least one external data source to each data subset reference based on the availability and the priority criteria, and controls the communication device to communicate with at least one external data source based on the respective communication priority assigned to each data subset reference to receive at least one data subset via the assigned external data source for storage on the storage device.

an onboard communication device configured to communicate with a plurality of external data sources;

an onboard storage device, wherein the onboard controller is further configured to repeatedly determine the availability of each of the plurality of external data sources and adjust the priority levels of the data subset references as the current vehicle location changes configured to store a data set comprising a plurality of data subset references, each of the data subset references having a respective one of a plurality of priority levels assigned thereto; and

an onboard controller configured to automatically determine an availability of each of the plurality of external data sources at a current vehicle location, automatically assign a respective communication priority for the current vehicle location to each of the respective data subset references based on the availability of each of the plurality of external data sources at the current vehicle location and the respective priority levels assigned thereto, automatically assign at least one of the plurality of external data sources at the current vehicle location to each of the data subset references based on the availability and the priority levels, and automatically control the communication device to communicate with at least one of the external data sources at the current vehicle location based on the respective communication priority assigned to each of the data subset references to receive at least one data subset via the assigned external data source for storage on the storage device.

2. The vehicle information gathering system according to claim 1, wherein

each of the plurality of priority levels is based on at least one of data type, size, preferred external data source, preferred connection protocol, importance, time criticality, vehicle power supply charging state, vehicle travel state and security level.

3. The vehicle information gathering system according to claim 1, wherein

the controller is configured to control the communication device to communicate with the at least one of the external data sources so that the at least one data subset is pushed to the storage device from the at least one of the plurality of external data sources.

4. The vehicle information gathering system according to claim 1, wherein

the communication device comprises a plurality of communication interfaces configured to communicate with the plurality of external data sources.

5. The vehicle information gathering system according to claim 4, wherein

the plurality of communication interfaces includes at least two of a telematics interface, a mobile interface, a mobile device tethering interface, a satellite interface, a wireless Internet interface, a wired Internet interface, an infrastructure communication interface and a vehicle-to-vehicle communication interface.

6. The vehicle information gathering system according to claim 1, wherein

the controller is further configured to assign a respective trigger event to each of the respective data subset references, and to automatically control the communication device to begin receiving the corresponding data subset only upon determining that the assigned trigger event has occurred.

7. The vehicle information gathering system according to claim 1, wherein

the controller assigns the respective communication priority to each of the respective data subset references based on at least one of the plurality of priority levels representing a prescribed vehicle travel state, and the controller automatically controls the communication device to communicate with at least a certain one of the external data sources instead of at least one other of the external data sources based on a detected vehicle travel state of the vehicle in relation to the prescribed vehicle travel state.

8. The vehicle information gathering system according to claim 7, wherein

the controller automatically controls the communication device to communicate with the at least a certain one of the external data sources instead of the at least one other of the external data sources while the detected vehicle travel state indicates that the vehicle is stationary.

9. The vehicle information gathering system according to claim 7, wherein

the controller automatically controls the communication device to communicate with the at least a certain one of the external data sources instead of the at least one other of the external data sources while the detected vehicle travel state indicates that the vehicle is moving.

10. The vehicle information gathering system according to claim 1, wherein

the controller assigns the respective communication priority to each of the respective data subset references based on at least one of the plurality of priority levels representing a threshold vehicle power supply level, and the controller automatically controls the communication device to communicate with at least one of the external data sources based on a detected vehicle power supply level in relation to the threshold vehicle power supply level.

11. The vehicle information gathering system according to claim 10, wherein

the controller automatically controls the communication device to communicate with at least one of the external data sources while the detected vehicle power supply level is above a prescribed level.

12. The vehicle information gathering system according to claim 1, wherein

the controller assigns the respective communication priority to each of the respective data subset references based on at least one of the plurality of priority levels representing a prescribed data source security condition, and the controller automatically controls the communication device to communicate with at least one of the external data sources based on a detected security condition of the at least one of the external data sources in relation to the prescribed data source security condition.

13. The vehicle information gathering system according to claim 12, wherein

when the data source security condition represents a secured data source, the controller automatically controls the communication device to communicate with the at least one of the external data sources for which the detected security condition indicates a secured data source.
