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: Systems and methods of diagnosing sensor performance of an ultra wide band (UWB) sensor localization for a vehicle are provided. The method comprises receiving sensor signals from at least four UWB anchors and a UWB tag for a time period. The sensor signals represent anchor coordinates and real-time distances between the tag and each anchor. The method comprises aligning the sensor signals to define aligned data. The method comprises calculating a predicted location of the UWB tag based on the aligned data and a least square of error to define a first constructed matrix and a second constructed matrix. 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.

Abstract: A wireless communication system for a vehicle includes a wireless access point (AP), an ultra-wide band (UWB) system, a communication link, a controller, and a vehicle system. The UWB system is in communication with the wireless AP via a communication link. The wireless communication system is operable to detect, via the wireless AP, a request for localized wireless communication. The UWB system requests the wireless AP to generate a clear to send (CTS) transmission, which includes selecting an ultra-wide band (UWB) channel, mapping the UWB channel to a plurality of WiFi channels, and transmitting, by the wireless AP, the CTS transmission to each of the plurality of WiFi channels. The UWB system then transmits a UWB message.

Abstract: Presented are control systems for governing analog and digital radio services in motor vehicles, methods for making/using such systems, and vehicles equipped with such systems. A method of controlling a vehicle includes an in-vehicle radio tuner receiving selections of broadcast radio stations output by analog signals and/or streaming radio stations output by digital signals. A vehicle controller retrieves a memory-stored broadcast station service (BSS) map with a service contour containing available broadcast radio stations having sufficient signal strength within a designated area. The controller receives geopositional data indicative of the host vehicle's location, and accesses a remote database to retrieve an updated BSS map that corresponds to the vehicle's location. The controller then determines if the stored BSS map corresponds to the updated BSS map; if not, the radio tuner responsively displays an updated list of available stations revised to reflect available stations contained in the updated BSS map.

Abstract: An advertisement system includes a tuner, an error detection and correction circuit, a decoder, and an output device. The tuner is operational to listen on a first channel of a plurality of channels for a first received packet during a current scan window. The error detection and correction circuit is operational to command the tuner to listen on a second channel of the plurality of channels within the current scan window for a second received packet in response to (i) an incomplete reception of the first received packet or (ii) the first received packet having uncorrectable errors, and correct the first received packet to create a first advertisement packet in response to the first received packet being received and correctable. The decoder is operational to decode the first advertisement packet to generate first advertisement information. The output device is operational to present the first advertisement information as first advertisement data.
