    Abstract: A method for smart guided selection of networks includes detecting a wireless connectivity issue between. The in-vehicle network device is inside a vehicle, and the network access device may be inside or outside the vehicle. The method further includes receiving network data. The network data includes a list of available networks and network performance characteristics of each of the available networks. The method includes predicting, using machine learning, quality of service (QoS) metrics of the available networks along a trip of a vehicle and selecting a one or more networks from the list of available networks for one or more in-vehicle network devices based constraint solving on the predicted QoS metrics of the list available networks and QoS constraints.

    Abstract: A method for in-vehicle localization of a mobile device includes receiving, in real time, sensor data from a plurality of UWB sensors inside a vehicle. The plurality of UWB sensors includes a plurality of UWB anchors and a UWB tag, which is part of the mobile device. The method further includes determining a plurality of location candidates of the UWB tag based on the sensor data received, determining a plurality of sensed current locations of the UWB tag and a plurality of probabilities for each of the plurality of sensed current locations of the UWB tag using a Gaussian Kernel Density Estimation (KDE), tracking a motion of the UWB tag, and determining a real-time position of the UWB tag using a Bayesian estimation.

    Abstract: Systems and methods for diagnosing sensor performance of a UWB sensor localization are provided. The system comprises a UWB tag, at least four UWB anchors, and a gateway. The gateway comprises an ECU arranged to receive sensor signals from the UWB anchors. The ECU comprises a preprocessing module arranged to align the sensor signals defining aligned data and is arranged to determine intersections of the aligned data defining points of intersections. The system further comprises a clustering module arranged to cluster the points of intersections defining at least one cluster of points of the UWB anchors to calculate a clustering quality and a clustering variance of each of the at least one cluster. The ECU is arranged to find a clustering contribution of each anchor defining a first contribution low of one of the anchors and is arranged to determine an erratic anchor based the first contribution low.

    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 digital key sharing system includes an electronic circuit and a first server computer. The electronic circuit is configured to store a plurality of digital keys, receive a plurality of key sharing requests, and generate a plurality of features in response to the plurality of key sharing requests. The first server computer is in wireless communication with the electronic circuit and is configured to generate an alert signal in response to finding one or more anomalies in the plurality of features to initiate a notification to a primary user device associated with the electronic circuit, and send a suspend notification signal to the electronic circuit in response to the finding of the one or more anomalies in the plurality of features. The electronic circuit is further configured to suspend use of the plurality of digital keys in response to reception of the suspend notification signal.
