    Abstract: Systems and methods of harvesting wireless energy for climate control in a cabin of a vehicle are provided. The method comprises receiving an electromagnetic (EM) signal of EM radiation having EM energy to define an EM current. The method further comprises filtering the EM energy to regulate the EM current converting the EM current to direct current. The method further comprises storing the direct current for powering a battery-free wireless sensing unit and powering the battery-free wireless sensing unit with the direct current. After powering the battery-free wireless sensing unit, the method comprises sensing an actual condition in the cabin, the actual condition being one of actual temperature and actual humidity in the cabin. Furthermore, the method comprises adjusting one of temperature and humidity in the cabin in response to a difference between the actual condition and a set condition.

    Abstract: Near-real-time monitoring and analysis of a road segment are described, and include a remotely-located controller that is arranged to wirelessly communicate with a plurality of connected vehicles. This includes periodically capturing vehicle positional data and associated temporal data that are communicated from a subset of the connected vehicles, wherein the subset of the connected vehicles traverse a road segment associated with the digitized roadway map. Vehicle positional data and the associated temporal data are analyzed over a period of time, including evaluating the vehicle positional data in context of the digitized roadway map. Occurrence of an anomalous traffic pattern for the road segment can be detected based upon the evaluating of the vehicle positional data in context of the digitized roadway map and the associated temporal data. A control action is executed based upon detection of the occurrence of the anomalous traffic pattern for the road segment.

    Abstract: In one example implementation, a computer-implemented method includes receiving, by a host processing device, timestamps from a vehicle processing system of a target vehicle, the timestamps being determined based at least in part on parking area data for a target parking area and vehicle data for the target vehicle. The method further includes calculating, by the host processing device, an arrival rate and a service rate based on the timestamps. The method further includes calculating, by the host processing device, a probability of parking availability for the target parking area based at least in part on the arrival rate and the service rate. The method further includes controlling, by the host processing device, the vehicle based at least in part on the probability of parking availability for the target parking area.

    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 vehicle crowd sensing system and method of selective sensing for the vehicle crowd sensing system. The method, in one implementation, involves receiving a plurality of detection reports from a first set of vehicles, each detection report including an event, a position qualifier of the event, and a severity qualifier of the event; developing an inherent error model for the event that includes a compilation of the position qualifiers of the event and the severity qualifiers of the event; and determining a resampling instruction for the event. The resampling instruction is based on an action model and the action model is at least partly a factor of the inherent error model.
