The eTrailer - Intelligent hybridization for heavy duty commercial vehicles: Electric drive installed in a semi-trailer and integrated in the truck trailer overall brake system control leading to significant fuel savings

摘要

Shown is an industry first solution for integration of an electric drive in a trailer combined with a holistic control approach by the overall vehicle brake system consisting of the trailer- and the truck-EBS without the need for additional truck/trailer communication lines, sensors or ECUs. The eTrailer is forming a hybrid vehicle combination together with a conventional powered towing vehicle and it generates fuel savings by energy recuperation and reuse for traction purposes as well as powering auxiliaries like coolers in trailer. Presented are design and test results of the WABCO eTrailer Prototype including basics of the overall control strategy.
