Abstract:
A method for communicating using a hybrid vehicle communications network including a combination of wired and wireless electronic control units (ECUs) and wired and wireless peripherals. The network includes a plurality of ECUs that include a plurality of wireless ECUs. The network also includes a plurality of peripheral devices, where one or more of the peripheral devices receive commands from one or more of the ECUs and one or more of the peripheral devices provide signals to the ECUs, and where the plurality of peripherals include at least one wireless peripheral. Wireless transmission signals transmitted from one of the wireless peripherals is received by all of the wireless ECUs. The method performs an arbitration process where a message provided from one of the wireless ECUs is placed on a communications backbone based on a quality of the transmission signal from the wireless peripheral.
Abstract:
A method in a vehicle configured to communicate in a vehicle point-to-multipoint communication system is provided. The method includes selecting a transmission resource comprising a sub-channel frequency range and time slot on which to compete for communication rights, competing with one or more vehicles for communication rights on the transmission resource using a listen-before-talk algorithm, and transmitting vehicle data on the transmission resource won.A method in a communication system is provided. The method includes partitioning a vehicle travel pathway into a plurality of geographical bins, grouping the bins into one or more regions, mapping each bin in a region to a different transmission resource, preparing a data record containing the mapping of geographical bins to transmission resources, and providing the data record to one or more vehicles that travel down the travel pathway for identifying to the one or more vehicles the transmission resource on which to transmit data.
Abstract:
A system and method that enables large content data transfers to mobile platforms is provided. The mobile platform cache system and method provided build a cache suitable for large content data transfers using the available storage capacity of one or more frequently used, existing mobile devices. The provided mobile cache system and method prioritize available free or low cost communication protocols for data transfer to one or more mobile devices, enabling the use of free Wi-Fi communications or low cost communications, and minimizing the use of cellular data transmissions for large content data transfers.
