Abstract: A system for 5G MICO mode operation of a vehicle during an ignition off mode includes a telematics unit and a telematics communication mode controller. The controller monitors energy consumption by the telematics unit and estimates a total energy consumption of the telematics unit through a time period. The controller further compares the total energy consumption to a first threshold energy consumption and a second threshold energy consumption and, when the total energy consumption is less than the first threshold energy consumption, operates the telematics unit in a first mode including unrestricted communication. The telematics communication mode controller, when the total energy consumption is between the first threshold energy consumption and the second threshold energy consumption, operates the telematics unit in a second MICO mode and, when the total energy consumption is greater than the second threshold energy consumption, deactivates communications by the telematics unit.

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.
