<p>A combined power supply and electronic control circuit uses existing power supply wires to communicate ABS control signals between individual electronic control units, mounted at each wheel of a tractor and a trailer, and a central electronic control module. The central electronic control module communicates with the wheel mounted electronic control modules using low voltage hi-frequency AC carrier signals. Each wheel mounted electronic control unit is assigned a signature voltage and frequency, permitting simultaneous communications by all of the wheel mounted electronic control units with the central electronic control module.</p> |
