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 system and method for sharing a digital key for a vehicle. The system includes a first digital key device having a digital key stored thereon, a second digital key device, and a vehicle server. The first digital key device sends a request to the vehicle server for a key sharing session. The vehicle server commences a key sharing session in response to the request. The first digital key device shares the digital key to a second digital key device. The vehicle server ends the key sharing session.

Abstract: A vehicle system, for implementation at a subject vehicle, including a vehicle storage component having a device-discovery module that, when executed by a vehicle processing unit, determines, using vehicle communication hardware, presence of non-subject-vehicle devices. The storage component also includes a service-discovery module that, when executed, uses the communication hardware in determining needs of various devices including any of the non-subject-vehicle devices and any vehicle device. The storage component also includes a resource-discovery module that, when executed, determines what resources amongst the various devices available to serve the needs determined. The component also includes a grouping module that, when executed, establishes one or more groups amongst the various devices, yielding grouped devices of the various devices. The storage may also include a role-assignment module, a maintenance module, a soft-state-refresh module, and a broker module including an auction-and-bid protocol. The technology may include simply the storage device having any mentioned module, and processes performed.

Abstract: A telematics system for a mobile UE includes a telematics controller that is configured to communicate via a plurality of communication channels. The telematics controller determines, for each of the communication channels, a parameter related to data throughput and energy consumption to effect an uplink communication between the telematics controller and a second device when the mobile UE is in a low-power operating mode. The parameter related to data throughput and energy consumption to effect the uplink communication is compared with a threshold. One of the communication channels is selected based upon the parameter related to data throughput and energy consumption to effect the uplink communication. The telematics controller communicates with the second device via the one of the plurality of communication channels when the mobile UE is in the low-power operating mode.

Abstract: A computer-implemented method at a service facility for capturing vehicle state and service information (VSSI) is provided. The method includes: detecting the arrival of a vehicle at the service facility; initiating, by a processor at the service facility, the establishment of a secure communication link with the vehicle via an in-vehicle wi-fi hotspot; wirelessly retrieving, by the processor at the service facility from the vehicle, a subset of VSSI via the wi-fi hotspot, wherein the retrieved VSSI includes the subset of the VSSI that has changed since the last update of the VSSI to a cloud-based server and wherein the subset of the VSSI includes some, but not all of the VSSI; and scheduling a vehicle service based on service indications derived from the VSSI.

Abstract: A vehicle system virtualizing add-on device hardware for a vehicle application. The system includes a computer-readable storage device comprising a client application, middleware components, kernel-space components, and a vehicle application. The client application communicates with an add-on-device server application for virtualizing the add-on-device hardware component at the vehicle. The middleware, in various embodiments, includes an emulated system-call application-program-interface module that receives add-on-device-hardware data from the client application, sends the data to the kernel-space components after processing, and receives the data having been processed at the kernel space. The middleware includes a frameworks-and-abstraction module that receives add-on-device-hardware data, having been processed at the kernel space and the emulated system-call-application-program-interface module and after processing sends the data for use at the vehicle application. In some implementations the middleware and kernel space includes universal-serial-bus components configured to emulate analogous components of the add-on device.
