Method and apparatus for reducing data transfer rates from a vehicle data logger when a quality of the cellular or satellite link is poor

摘要

System and method for reducing data transfer rates when a quality of the cellular or satellite link (i.e., a long range wireless data link) is poor. Such a concept is particularly well suited to embodiments where the vehicle data being logged or collected includes position data, because consumers of vehicle data that includes position data often desire to have such data exported from the vehicle on frequent basis, so that the physical location of fleet vehicles can be tracked in real-time. In one embodiment, before transmitting data a current location of the vehicle is checked against known bad locations, and no data is sent when the current location is known to be bad. In another embodiment, if successful data transmission is not confirmed during a first time period, additional transmission attempts are delayed for a second time period.

主权项

1. A method for reducing data transfer rates when a quality of the cellular or satellite link is known to be problematical, leading to an undesirable amount of failed data transmissions, the method comprising the steps of:
(a) providing at least one known poor location for which data link quality is known to be problematical; (b) automatically collecting vehicle data from the vehicle during vehicle operation; (c) before transmitting the collected vehicle data to a remote computing site, automatically determining if a current position of the vehicle corresponds to a known poor location; and (d) if the current location corresponds a known poor location, then automatically storing the collected vehicle data for transmission from a different location, the different location not being a known poor location.
