A trailer tracking solution that requires no additional trailer hardware is now available from PeopleNet. Once connected to the tractor, the trailer’s unique serial number is sent to the PeopleNet on-board system, which in turn creates location-based hook and drop events for the trailer. Event information is stored, including the date/time, location, vehicle and trailer odometer reading. The Tethered Trailer Tracking solution uses the existing Power Line Communication (PLC) cable for exchanging data between the trailer’s ABS (antilock brake system) and the PeopleNet system through the Multi-Bus Adapter with a PLC chip.
