摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： 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.

摘要： A system of managing communications in a vehicle includes a telematics unit connected to the vehicle. The telematics unit is configured to execute a retransmission request protocol upon receipt of erroneous data. A command unit in communication with the telematics unit, the command unit having a processor and tangible, non-transitory memory on which instructions are recorded. The command unit is adapted to determine vehicle situational parameters at a beginning of a data communication cycle. The vehicle situational parameters including current location and navigation status of the vehicle. When a first retransmission according to the retransmission request protocol is detected, the vehicle situational parameters are updated. The command unit is adapted to determine a desirable value of a retransmission frequency for the retransmission request protocol based in part on the updated vehicle situational parameters. In one embodiment, the retransmission request protocol is Hybrid Automatic Repeat Request (HARQ).
