Mobile telemetry system
An automotive vehicle may include a processor configured to buffer records of vehicle information created at a scheduled acquisition rate, and to buffer event files of vehicle information created upon the occurrence of predetermined triggering events. The processor may be further configured to cause the buffered records to be wirelessly transmitted on a last-in first-out basis if a signal strength in a vicinity of the vehicle is greater than a first predetermined threshold, and to cause the buffered files to be wirelessly transmitted if the signal strength is greater than a second predetermined threshold.
1. An automotive vehicle comprising:
a modem configured to detect a wireless signal strength in a vicinity of the vehicle;
an antenna; and
a processor operatively arranged with the modem and antenna, and configured to (i) buffer records of vehicle information created at a scheduled acquisition rate, (ii) buffer event files of vehicle information created upon the occurrence of predetermined triggering events, (iii) cause the buffered records to be wirelessly transmitted via the antenna on a last-in first-out basis if the signal strength is greater than a first predetermined threshold, and (iv) cause the buffered files to be wirelessly transmitted via the antenna if the signal strength is greater than a second predetermined threshold.
2. The vehicle of claim 1 wherein the processor is further configured to archive buffered records as message files if the signal strength is less than or equal to the first predetermined threshold.
3. The vehicle of claim 2 wherein the processor is further configured to cause the archived message files to be wirelessly transmitted via the antenna if the signal strength is greater than a third predetermined threshold.
4. The vehicle of claim 3 wherein each of the archived message files has a size and wherein the third predetermined threshold depends on the sizes.
5. The vehicle of claim 1 wherein the processor is further configured to archive buffered event files if the signal strength is less than or equal to the second predetermined threshold.
6. The vehicle of claim 5 wherein the processor is further configured to cause the archived event files to be wirelessly transmitted via the antenna if the signal strength is greater than a third predetermined threshold.
7. The vehicle of claim 6 wherein each of the archived event files has a size and wherein the third predetermined threshold depends on the sizes.
8. The vehicle of claim 1 wherein the buffered records are wirelessly transmitted at a scheduled transmission rate.
9. The vehicle of claim 8 wherein the scheduled acquisition rate and the scheduled transmission rate are approximately equal.
10. The vehicle of claim 1 wherein the files each have a size and wherein the processor is further configured to cause the files to be wirelessly transmitted based on the sizes.
11. The vehicle of claim 10 wherein the second predetermined threshold depends on the sizes.
12. The vehicle of claim 1 wherein the processor is further configured to, in response to receiving a confirmation that particular records or files wirelessly transmitted via the antenna have been received at a server remote from the vehicle, cause the particular records or files to be deleted.
