16. A control system for a vehicle configured to communicate over a direct current power line that is routed though the vehicle, the system comprising:
-
a transmitting device mounted on the vehicle and being configured to transmit a first carrier signal having either a first predetermined frequency or a second predetermined frequency over the direct current power line, wherein the transmitting device determines whether to transmit the first carrier signal having the first predetermined frequency or second predetermined frequency based on whether a second carrier signal is being transmitted having either the first predetermined frequency or the second predetermined frequency; and a receiving device mounted on the vehicle and being configured to automatically tune to the frequency of the first carrier signal, receive the first carrier signal and filter signals not having the transmitted frequency of the first carrier signal, the receiving device activating an electrical device in response to the first carrier signal. - View Dependent Claims (17, 18, 19, 20)
