Abstract: Presented are systems and methods for extracting lane-level information of designated road segments by mining vehicle dynamics data traces. A method for controlling operation of a motor vehicle includes: determining the vehicle's location; identifying a road segment corresponding to the vehicle's location; receiving road-level data associated with this road segment; determining a turning angle and centerline for the road segment; receiving vehicle data indicative of vehicle locations and dynamics for multiple vehicles travelling on the road segment; determining, from this vehicle data, trajectory data indicative of start points, end points, and centerline offset distances for these vehicles; identifying total driving lanes for the road segment by processing the trajectory data with a clustering algorithm given the turning angle and centerline; extracting virtual trajectories for the driving lanes; and commanding a vehicle subsystem to execute a control operation based on an extracted virtual trajectory for at least one driving lane.

Abstract: In various embodiments, methods, systems, and vehicles are provided for distance determinations using cameras from different vehicles. The system includes a first camera onboard a first vehicle, providing a first image, the first image having therein an object of interest (OOI) for which a distance from the first vehicle is desired; and a second camera, providing second camera data including a second image having therein the OOI. The system further includes a control module configured to process and time synchronize first camera data and second camera data to generate a distance determination for the OOI, using the first camera data, the second camera data, and a distance between the first and second camera.

Abstract: A processor-implemented method by a message recipient in a vehicle or on a mobile device for decoding overlapping wireless messages is provided. The method comprises: receiving a first message from a first message sender that overlaps with a second message received from a second message sender; estimating, in a first signal recovery phase, a received data symbol (d0) from the first message and a channel impulse response (h1) corresponding to a data channel between the message recipient and the second message sender; estimating, in a second signal recovery phase, a received data symbol (d0)′ from the first message and a received data symbol (d1) from the second message; and reconstructing the first message from the estimated data symbol (d0) estimated in the first signal recovery phase and estimated data symbol (d0)′ estimated during the second signal recovery phase and reconstructing the second message from the estimated data symbol (d1) estimated during the second signal recovery phase.

Abstract: A gateway apparatus for managing local-device access to vehicle data, including an input/output component for receiving requests for vehicle data from a local device and sending vehicle data to the local device. The apparatus also includes a tangible processing unit in communication with the input/output component and the input/output component, and a non-transitory computer-readable storage device. An access unit of the apparatus has access-unit code that receives, by way of the input/output component, a request for the vehicle data from a local device and determines whether the gateway apparatus may satisfy the request. A control unit has control-unit code that, when executed by the processing unit, determines what vehicle data will be provided. A data unit has data-unit code that prepares the vehicle data to be provided to the local device, and sends the vehicle data to the local device by way of the input/output component.

Abstract: Disclosed are vehicle communications networks for adapting user information using crowd-sensed contextual data, computer-executable instructions for provisioning such content/information, and vehicles equipped with a telematics system for adapting driver information using contextual data from vehicle participatory sensing systems. A disclosed method for provisioning information to occupants of a motor vehicle includes determining trip characteristics, including vehicle and driver data, for a current trip of the vehicle, and determining trip characteristics for previous trips that correspond to the current trip. The vehicle's communications system receives, over a distributed computer network from a vehicle participatory sensing system aggregating data from participative vehicles, operational data for the current trip as sensed by the participative vehicles. The received operational data is analyzed with the current and previous trip characteristics to determine a predicted trip duration and/or a predicted trip route. An electronic user interface of the vehicle outputs the predicted trip duration and/or route.

Abstract: A portable communication device, for implementation with a host vehicle of transportation having an on-board diagnostics port and a limited-access head-unit display. The device includes an on-board diagnostics connector sized and shaped to connect to the on-board diagnostics port of the host vehicle, a hardware-based processing unit in communication with the on-board diagnostics; and a non-transitory storage device in communication with the processing unit, the storage device. The storage includes a media-options presentation module that, when executed by the processing unit: sends, by way of the on-board diagnostics connector and port, media-options data to the host vehicle for presenting user media options by way of the limited-access head-unit display; and receives user-selection data responding to the user media options. The storage also includes a media streaming module that, when executed obtains streaming media based on the user-selection data, and sends the streaming media to the host vehicle for presentation.
