Abstract
Presented are intelligent vehicle communications systems for cellular link monitoring and failure detection, methods for making/using such systems, and vehicles equipped with such systems. A method for operating a wireless-enabled vehicle component of a motor vehicle includes a cellular communications device of the vehicle component detecting an uplink (or downlink) network data packet transmitted by (or to) the vehicle. An electronic vehicle controller then establishes an observation period as a function of the time at which the network data packet was transmitted. The opposite downlink (or uplink) of the wireless-enabled vehicle component is monitored to determine if a downlink (or uplink) network data packet is received within the observation period, thereby indicating detection of a cellular link failure. Responsive to a detected cellular link failure, the vehicle controller conducts a supplemental assessment of the opposite link and/or a corrective action to re-establish a data link for the opposite link.
