HYBRID WIRELESS-WIRED ARCHITECTURE BASED ON POWER LINES FOR INTRA-VEHICULAR COMMUNICATION

摘要

A hybrid vehicle communications network including a combination of wired and wireless ECUs and wired and wireless peripherals. A communications backbone, either a CAN bus or a powerline, is electrically coupled to each of the ECUs. The wireless peripherals provide wireless signals to all of the wireless ECUs and each wireless ECU provides data messages on the backbone based on the signals received from the wireless peripherals to be received by a target ECU. Also, one or more of the ECUs puts messages on the backbone to be transmitted wirelessly by all of the wireless ECUs to be received by a wireless peripheral.
