This task force reports to the Truck and Bus Electrical Systems Committee. The Task Force is to develop an SAE Standard for Automated Coupling that will provide the minimum design, operational 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 employs connections at the tractor fifth wheel and trailer king pin locations. • Physical tractor fifth wheel and trailer king pin electrical connector coupling interface requirements and characteristics to ensure interchangeability, • Connector electrical connections including contact assignment/definition, sizes, construction requirements, performance requirements and tests,
• Cabling for electrical connections including definitions, sizes, construction requirements, performance requirements and tests,
• Next generation powering considerations, the predominant (nominal) tractor/trailer power interface is 12Vdc, optional 24Vdc and 48Vdc connections should be investigated. Any tractor, regardless of system voltage, must be able to connect to a 12Vdc trailer.
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)
