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: Methods and systems are disclosed for participative sensing of road friction conditions by vehicles, collection of the friction data from a large number of vehicles by a central server, processing the data to classify friction conditions by roadway and locale, and sending notifications of the friction conditions to vehicles as appropriate. A large number of vehicles use participative sensing systems to identify road friction estimates which are reported to the central server—where the vehicles use sensor data and vehicle dynamic conditions to estimate friction. The central server stores and aggregates the friction data, filters it and ages it. Vehicles requesting advisories from the central server will receive notices of road friction conditions which may be significant based on their location and heading. Driver warnings can be issued for low friction conditions ahead, and automated vehicle systems may also respond to the notices.

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.

Abstract: A method for sharing a digital key associated with a vehicle by a cascaded key delegation system includes issuing, by a requestor device, a public key certificate to an initial delegator device that is part of a cloud delegation service. The public key certificate enables the initial delegator device to grant delegation rights the vehicle. The method also includes issuing, by the initial delegator, an intermediate public key certificate to a subsequent delegator that is part of the cloud delegation service. The intermediate public key certificate grants the delegation rights to the subsequent delegator.
