This task force reports to the Truck and Bus Brake Supply and Control Components Committee. The Task Force is tasked with developing an SAE Standard for Automated Coupling that will provide the minimum design and performance requirements for a uniform coupling system between a towing tractor or converter dolly and a towed trailer using a male plug module at the fifth wheel and a female receptacle module at the trailer king pin, each housed in a protective cover and containing mechanical, electrical/electronic and pneumatic connections that are designed to mate together. The Task Force will oversee the following technical issues related to Automated Coupling for tractors and trailers over 10,000 lbs (4500 Kg) GVWR with 12 V nominal supply voltage designed primarily for on highway use:
• Automated Coupling Systems that employ connections at the tractor fifth wheel and trailer king pin locations.
• Physical tractor fifth wheel and trailer king pin coupling mechanical and pneumatic interface requirements and characteristics of a fully automated coupling system to ensure interchangeability,
• Connector for pneumatic connections for towing and towed vehicles, definitions, performance requirements and tests,
• Location and allowable envelope of electrical and pneumatic connections between towing vehicles and trailers for semi and fully automated coupling systems at the tractor fifth wheel and trailer king pin locations,
• Mechanical interchangeability between manual, semi-automated and fully automated,
• Compatibility for intermodal on TOFC (Trailer on Flatcar) applications.
The various components of the system include:
• EPI male plug module with protection cover (mounted at the trailer king pin)
• EPI female socket module with protection cover (mounted at the tractor fifth wheel)
