Hitch Angle Measurement Device

摘要

As part of a project to demonstrate that an unmanned ground vehicle (UGV) could remotely back up with a trailer, a simple proof-of-concept device was designed to measure the angle between a high-mobility multipurpose wheeled vehicle (HMMWV) pintle hook and a trailer tow bar. A suitable algorithm could compute the UGV steering angle required for a trailer to follow a given reverse path and would be a function of the angle between the UGV and the trailer. This report gives the details of a design for a hitch angle measurement device (HAMD) to be used as input to a steering transfer function. Derivation of the transfer function is not included.
