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: A system for providing updates in a vehicle includes a server device configured for providing an OTA campaign update and the vehicle. The vehicle includes a device including software to be upgraded by the over-the-air campaign update and a low voltage battery providing low voltage power. The system further includes a battery providing high voltage power and an accessory power module configured to transform the high voltage power into low voltage power and including programming to estimate an available power of the low voltage battery. The system further includes a controller monitoring the available power, comparing the available power to a threshold, and, when the available power is less than the threshold, commanding the accessory power module to transform the high voltage power to provide the low voltage electrical power. The controller further schedules receiving the update based upon the available power and updates the device with the update.

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.

Abstract: A system for updating vehicle time information includes a communication device configured to wirelessly communicate with a wireless network using a network communication protocol. The system also includes a processing unit configured to assess communications between the vehicle to determine whether a condition related to a potential local time offset error exists, and based on determining that the condition exists, transmit a message supported by the communication protocol to the wireless network. The message is configured to prompt the wireless network to return a response message including a local time offset. The process is also configured to update a vehicle local time record based on the local time offset.

Abstract: A mobile communication system of a motor vehicle includes a primary antenna. The system further includes a telematics module having a processor and at least one memory including a computer program code. The memory and the computer program code are configured to, with the processor, cause the system to detect a predetermined vehicle event and measure a primary signal quality of the reference signal received at the primary antenna. The memory and the computer program code are configured to, with the processor, cause the system to determine a maximum primary signal quality and compare the maximum primary signal quality with a threshold. The memory and the computer program code are configured to, with the processor, cause the system to determine a defect in the primary antenna and activate a diagnostic trouble code associated with the defect, in response to determining that the primary maximum signal quality is below the threshold.

Abstract: A system and method of selecting a modem for cellular communications while the vehicle is in a primary propulsion off state. The method includes: detecting a transition from a primary propulsion on state to a primary propulsion off state of the vehicle; after detecting the transition from the primary propulsion on state to the primary propulsion off state, measuring one or more cellular connectivity parameters for a plurality of modems included in the vehicle; based on the cellular connectivity parameter(s), selecting a modem of the plurality of modems; after selecting the modem of the plurality of modems, then turning off non-selected modem(s) of the plurality of modems, wherein the non-selected modem(s) include the plurality of modems other than the selected modem; and sending a selected modem indication to a remote server, wherein the selected modem indication indicates to the remote server to use the selected modem when sending messages to the vehicle.

Abstract: A telematics system for a mobile UE includes a telematics controller that is configured to communicate via a plurality of communication channels. The telematics controller determines, for each of the communication channels, a parameter related to data throughput and energy consumption to effect an uplink communication between the telematics controller and a second device when the mobile UE is in a low-power operating mode. The parameter related to data throughput and energy consumption to effect the uplink communication is compared with a threshold. One of the communication channels is selected based upon the parameter related to data throughput and energy consumption to effect the uplink communication. The telematics controller communicates with the second device via the one of the plurality of communication channels when the mobile UE is in the low-power operating mode.

Abstract: Presented are vehicle control systems and logic for provisioning remote vehicle services (RVS), methods for making/using such systems, and wireless-enabled vehicles executing RVS operations governed by such systems. A method of controlling an RVS operation of a vehicle includes a vehicle controller receiving, either directly or indirectly, a request to activate the RVS operation. Responsive to receiving the RVS activation request, wireless signal data is collected to determine wireless signal states of the subject vehicle and of multiple crowd-sourced vehicles proximal to the subject vehicle. Using the host vehicle's and crowd-sourced vehicles' wireless signal states, a signal state heatmap is generated with a spatial mapping of signal state magnitudes as a map overlay. The heatmap visualizes a signal state magnitude in an area surrounding the host vehicle. If this signal state magnitude exceeds a preset minimum threshold, the vehicle controller commands a resident vehicle subsystem to activate the RVS operation.

Abstract: A system for multi-mode connectivity for group vehicle activity and for over-the-air updates via time synchronized device-to-device side-link communications is provided. The system includes a remote communication device configured to transmit data, vehicles to receive the data, and a computerized controller. The controller includes programming to analyze hardware of the vehicles to identify alpha vehicles including excellent wireless capabilities, monitor signal strength between the vehicles and the remote communication device to identify vehicles including relatively strong communication strength, and determine a portion of the plurality of vehicles including highly functioning vehicles including the capabilities and communication strength. The controller generates a series of data transfers to first transfer the data from the remote communication device a highly functioning vehicle and subsequently transfer the data from the highly functioning vehicle to a second of the vehicles and transfers the data. The highly functioning vehicle retransmits the data to the second vehicle.
