Abstract
An odometer monitor for monitoring the connectivity status of a mobile data terminal to a vehicle is a module defined in a data processor of the mobile data terminal. The monitor is operable to detect successive timed poll events originating in the mobile data terminal and listen for arrival of corresponding odometer update values from a vehicle tracking device connected to an information bus of the vehicle. Successive odometer updates are compared to calculate the distances travelled between updates, and to make a determination of connectivity status of the mobile data terminal relative to the vehicle based on whether or not the calculated distances are above or below a preset maximum distance. The odometer monitor can verify whether the mobile data terminal remains connected to the same vehicle by checking a vehicle identity module, which may be located in the vehicle tracking device.
