Abstract: Systems and methods are provided for vehicular computation management. The system includes, onboard a vehicle, electric control units (ECUs), a battery, a communication system, and a controller. The controller is configured to monitor energy consumption, operate the vehicle as a computational hub when the energy consumption is less than a threshold, including providing computational resources to an external node, determine whether the vehicle has excess energy and computational capacity when the energy consumption is equal to or greater than the threshold, including determining a usage of each of the ECUs and determining an energy consumption of tasks executing thereon, and operate the vehicle as a hybrid computational hub when the vehicle has excess energy and computational capacity, including providing excess computational capacity of the ECUs to the external node.

Abstract: 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).
