Publication number: 20230399001Abstract: Upon determining that a vehicle is operating within an area, a stop time for the vehicle in the area is estimated based on operation data from an infrastructure element in the area. A vehicle sensor that is available to transition to a low power mode is identified based on the estimated stop time. Upon stopping the vehicle in the area, the available vehicle sensor is transitioned to the low power mode based on the estimated stop time being greater than a threshold.Type: ApplicationFiled: June 13, 2022Publication date: December 14, 2023Applicant: Ford Global Technologies, LLCInventors: Krishna Bandi, Swetha Shailendra, Helen E. Kourous-Harrigan, Nancy Lewis

Publication number: 20230379674Abstract: A system and method for operating a vehicle operating on a route that will pass within a predetermined distance of a smart infrastructure node (IX Node) includes: retrieving, prior to receiving a message from the IX Node, data about the IX Node including (a) an IX Node assist zone based on an effective broadcast range of the IX Node, (b) an IX Node field of view area that is within the IX Node assist zone and that is defined by a field of view of one or more IX Node sensors, and (c) available services from the IX Node; and selecting a vehicle application for operation on the route while in the IX Node assist zone based on the IX Node field of view area, and the available services from the IX Node, and/or a type and accuracy of one or more IX Node sensors.Type: ApplicationFiled: May 17, 2022Publication date: November 23, 2023Applicant: Ford Global Technologies, LLCInventors: Helen E.

Publication number: 20230138084Abstract: A three-dimensional grid model of a traffic scene can be determined based on grid elements. Weights can be determined for the grid elements of the three-dimensional grid model corresponding to priority regions and occluded grid elements. Grid coverage for respective stationary sensors can be determined based on the grid elements of the three-dimensional grid model. A matrix can be determined based on the grid coverage of the plurality of stationary sensors. An optimal subset of stationary sensors can be determined based on applying a greedy search algorithm to the matrix, the weights and costs corresponding to the plurality of stationary sensors to maximize the ratio of grid coverage to the cost based on poses of the plurality of stationary sensors.Type: ApplicationFiled: November 4, 2021Publication date: May 4, 2023Applicant: Ford Global Technologies, LLCInventors: Helen E. Kourous-Harrigan, William Thomas Buller, Jeremy Graham, Susan Janiszewski, Colin Brooks

Patent number: 11637754Abstract: A set of first candidate topologies of first candidate roadside infrastructure nodes at respective mounting locations in a geographic area is randomly generated. For each of the first candidate topologies, first simulations, including detection of objects according to selected sensor parameters, installation parameters, and environment parameters for the candidate nodes at the respective mounting locations, are executed. First fitness scores are determined for each of the first candidate topologies by comparing results of the first simulations to ground truth data. Upon identifying one of the first fitness scores as exceeding a threshold, the candidate topology associated with the identified first fitness score is identified for deployment.Type: GrantFiled: January 15, 2021Date of Patent: April 25, 2023Assignee: FORD GLOBAL TECHNOLOGIES, LLCInventors: Gaurav Pandey, Jeffrey Thomas Remillard, Mostafa Parchami, Helen E. Kourous-Harrigan, John Anthony Lockwood

Patent number: 11615702Abstract: A system comprising a computer including instructions to collect object data about each of a plurality of objects within a zone from sensors on a roadside infrastructure unit. The zone includes a road intersection. The object data includes an object type, an object location, an object speed and an object direction of travel for each object. The computer further includes instructions to determine, based on the object data, an availability level for execution of one or more paths through the road intersection by a vehicle wherein the availability level for each of the one or more paths is based on a likelihood of interference between any of the objects and the vehicle as the vehicle traverses the respective path. The computer further includes instructions to transmit an availability message to the vehicle including the availability level for each of the one or more paths.Type: GrantFiled: September 11, 2020Date of Patent: March 28, 2023Assignee: Ford Global Technologies, LLCInventors: Linjun Zhang, Helen E.
