There are several new technologies being developed for tractor-trailer connections. Here are some of the latest advancements:
- Next Generation Tractor-Trailer Interface: The Technology & Maintenance Council (TMC) is working on defining the evolutionary direction of tractor-trailer connectivity. They are evaluating potential concepts for a new connector to replace the long-standing SAE J560 standard connection, which is in need of modernization to meet new customer and supplier recommendations and allow for the advancement of technologies now available to the trailer market.
- Multivoltage Systems: With advancements in electric and highly automated vehicles, telematics, solar power, two-way power flow, regenerative trailer braking, and electromechanical braking, there is a growing need for 24-volt and even 48-volt systems to support more complex tractor-to-trailer connectivity options. This shift towards multivoltage systems is expected to become commonplace in less than 10 years.
- ZF’s Innovations: ZF is showcasing its complete truck-trailer technologies, including unintended cargo movement detection with its CargoCam sensor, which can flag issues to a fleet orchestration system for corrective action. They are also demonstrating how their combined truck and eTrailer technologies can lead to significant fuel savings and CO2 emission reductions. ZF’s eTrailer includes advanced traction functionalities that boost safety and support drivers of all experience levels.
- Telematics and Data Communication: The industry is moving towards more sophisticated data communication between tractors and trailers. This includes the expansion of telematics, which will likely require greater power demands exceeding 12 volts, leading to the adoption of 24 volts or 48 volts over time.
- Electrical and Data Needs in Trailer Safety and Telematics: TMC has published a position paper containing guiding principles for what must be supported in terms of power, command control, and data needs in trailer safety and telematics technology.
These developments indicate a significant shift towards more integrated, efficient, and technologically advanced tractor-trailer connections, aiming to improve safety, efficiency, and sustainability in the transportation industry.
