Abstract: Systems and method are provided for transmitting data from a vehicle using a Wi-Fi network. A method includes: collecting, by a processor, performance data associated with a plurality of access points in the Wi-Fi network; segmenting, by a processor, a route into a plurality of route segments; mapping, by a processor, the plurality of access points to the plurality of route segments; selecting, by a processor, a set of access points from the plurality of access points based on the collected performance data, wherein the set of access points comprises a selected access point for each route segment of the plurality of route segments; predicting, by a processor, a scanning channel based on the set of access points and a current location of the vehicle; and selectively transmitting, by a processor, packet data based on the set of access points, the scanning channel, and the associated performance data.

Abstract: Methods and apparatus are provided for controlling a vehicle. In one embodiment, a method includes: receiving, by a processor, vehicle position data from the vehicle; processing, by the processor, vehicle position data with vehicle position data from other vehicles to determine a lane topology; processing, by the processor, the vehicle position data to determine traffic conditions within a lane of the lane topology; generating, by the processor, a map for controlling the vehicle based on the lane topology and the traffic conditions.

Abstract: Presented are systems and methods for deriving speed limits of designated road segments by mining large-scale vehicle data traces. A method for controlling operation of a motor vehicle includes: determining a current location of the vehicle; determining a designated road segment corresponding to the vehicle's location; receiving host speed data indicative of the vehicle's speed while travelling on the road segment for a calibrated timeframe; receiving crowd-sourced speed data indicative of the speeds of participatory vehicles while travelling on the road segment for the calibrated timeframe; accumulating a speed distribution function for the road segment based on the host and crowd-sourced speed data; generating a finite mixture model from the speed distribution function to estimate a speed limit range; selecting a speed limit candidate from the estimated speed limit range; and transmitting command signals to a vehicle subsystem to execute a control operation based on the selected speed limit candidate.
