Trailer communication system
East flatbed, refuse and dump trailers can now communicate critical intelligent data to the driver through an optional Power Line Carrier (PLC) communication system that utilizes MeritorWABCO Vehicle Control Systems’ Infolink Gateway communications capabilities. From an in-cab screen, drivers can monitor several trailer systems, including air system pressure and load-weight. With dump trailers, drivers can also tell from their cab if the trailer bed is completely down and cradled, and if the tailgate is closed and latched. “Through what is called ‘multiplexing’ additional digital and analog data can travel through the ABS power line already installed on the trailer,” explains John Pierce, director of engineering for East. “The Electronic Control Unit (ECU) now standard on East trailers is compatible with this system. For ease of customer identification and ordering we’re calling it the East Smart-Trailer system. The new system can be added on new trailers for the price of an in-cab screen, a few sensors, and the harnessing to connect to the PLC-compatible ECU. Working with MeritorWABCO we have been able to implement the system spe-cific to East trailers so that it only takes a small investment to receive huge operational benefits,” said Pierce.
The big operational benefit of this technology according to East, is the ability for the driver to approximate the weight of his load. “The East Smart-Trailer system measures the suspension pressure weight in pounds, essentially providing the driver with his ballpark load-weight. While the system does not provide a certified weight, it does allow the driver to avoid overloading his trailer, and to steer clear of fines by not exceeding legal load limits,” noted Pierce.
