Abstract: A method and system of resilient UWB target localization for a vehicle are provided. The system comprises a UWB tag arranged to be mobile and trackable by way of a sensor signal and at least three UWB anchors. Each anchor is in communication with the tag. The system further comprises a gateway in communication with the anchors. The gateway comprises an ECU arranged to receive sensor signals from UWB anchors. The ECU comprises a preprocessing module, a clustering module, and a Bayesian module. The preprocessing module is arranged to align sensor signals at an aligned timestamp to define aligned data. The clustering module is arranged to cluster points of intersections, defining a sensed location for each cluster. The Bayesian module is arranged to determine a real-time location of the tag based on a Bayesian probability function to match the sensed location with a predicted location of the tag.

Abstract: A warning system is provided for alerting a VRU of a predicted collision. The system includes one or more input devices for transmitting first and second input signals for associated first and second vehicles. The system further includes a UWB beacon communicating with a UWB tag of a VRU notification device carried by the VRU. A location of the UWB tag is trackable via a third input signal. The system further includes a computer having one or more processors and a non-transitory computer readable medium. The processor is programmed to determine the location of the VRU and further determine the predicted collision between the second vehicle and the VRU. The processor is further programmed to generate a notification actuation signal associated with the VRU at a tracked location. The VRU notification device notifies the VRU that the second vehicle is headed toward the predicted collision site in the crosswalk.

The method comprises determining a local error of each of the at least four UWB anchors based on the least square of error and comparing each local error with an error threshold to define a first threshold high. The method comprises determining an erratic anchor based on the first threshold high.
