60 GHz Wi-Fi As A Tractor-Trailer Wireless Harness
share
Reverse driving a truck is a challenging task for human drivers and self-driving software due to the lack for sensors on the trailer. Self-driving and conventional trucks have an increasing need to replace the legacy communication channels between the truck and the trailer to accommodate bandwidth and latency requirements when more sensors and features are added to the trailer to support driver assist features or self-driving functions, in addition to the need of automating the tractor-trailer hitching and unhitching, which is a complex process when using wires and connectors for communication between the truck and the trailer. In this paper, we address using a wireless harness between the tractor and the trailer based on Wi-Fi, in addition to discussing using Named Data networking protocol for communication between the truck and the trailer including handling interest and data packets. A Testbed is used to evaluate communicating different data types from one device to three devices over 802.11ac and it indicated a stable communication performance when Named Data Networking and Data Distribution Service were used. Using a wireless harness will ease the automation of trailer hitching and unhitching process and will eliminate the need for communication wires or connectors between the tractor and the trailers, therefore, reducing the complexity of the process.
