Patent number: 11262459Abstract: A position estimation unit (2) comprising a first transceiver device (3) and a processing unit (10) that is arranged to repeatedly calculate time-of-flight (TOF) for radio signals (x1, x2, x3, x4, x5, x6) sent pair-wise between two transceivers among the first transceiver device (3) and at least two other transceiver devices (7, 8, 9); calculate possible positions for the transceiver devices (3, 7, 8, 9), which results in possible positions for each transceiver device (3, 7, 8, 9); and perform Multidimensional scaling (MDS) calculation in order to obtain relative positions of the transceiver devices (3, 7, 8, 9) in a present coordinate system. After two initial MDS calculations, between every two consecutive MDS calculations, the processing unit (10) is arranged to repeatedly perform a processing procedure comprising translation, scaling and rotation of present coordinate system such that a corrected present coordinate system is acquired.Type: GrantFiled: March 14, 2018Date of Patent: March 1, 2022Assignee: VEONEER SWEDEN ABInventors: Olof Eriksson, Tobias Aderum, Driouichi Chafik, Meifang Zhu

Patent number: 10656286Abstract: An apparatus comprising a processor and a transceiver. The processor may (i) receive messages from a plurality of vehicles and (ii) determine relative coordinates of the vehicles based on the messages. The transceiver may (i) communicate the messages using a first channel in a first range and (ii) communicate short messages using a second channel in a second range. Communicating using the second channel may consume more power than communicating using the first channel. The messages may be sent from the transceiver to a cluster head within the first range. The short messages may communicate less data than the messages. The short messages may be sent directly to a target vehicle outside of the first range to determine an associated cluster head for the target vehicle. The messages may be sent to the target vehicle from the associated cluster head via the cluster head within the first range.Type: GrantFiled: September 12, 2019Date of Patent: May 19, 2020Assignee: VEONEER US INC.Inventors: Olof Eriksson, Tobias Aderum
