Publication number: 20220107635Abstract: According to the embodiments described herein, system and methods for determining relative pose of materials handling vehicles in an industrial environment may include utilizing UWB antenna array systems respective mounted on the materials handling vehicles to send mutually received information to determine the relative pose between the vehicles, determining one or more fields of each materials handling vehicle, and determining one or more overlapping fields between the materials handling vehicles based on the determined one or more fields and the relative pose. A vehicle control may be implemented based on the determined relative pose and the overlapping fields as a field enforcement, such as a control action to avoid collision between the vehicles.Type: ApplicationFiled: October 4, 2021Publication date: April 7, 2022Applicant: Crown Equipment CorporationInventors: Ryan Estep, Justin Bennett, Mike Etienne Ciholas, Ben Morelli, Chad Lefeld, Trisha Marie Luthman
