    Abstract: Processor-implemented methods and systems for aerodynamically optimizing a design geometry of a vehicle body using a convolutional neural network (CNN) are provided. The method may include receiving a signed distance function (SDF) data file that represents the design geometry of the vehicle body. The method includes receiving a range of inflow boundary conditions. The processor processes the SDF over the range of boundary conditions, using the CNN, to generate therefrom drag and lift outputs for the design geometry. The drag and lift outputs may be displayed in the form of one or more intensity maps.

    Abstract: Cab extender systems and methods are provided for reducing the aerodynamic drag on a pickup truck. A cab extender system includes a cab with a roof panel and a rear wall. The cab extends upward on the vehicle to the roof panel and the rear wall extends downward from the roof panel. A tailgate is disposed at a rear of the vehicle and a utility box extends between the rear wall and the tailgate. An extender extends in a rearward direction from the roof panel a length of between ten and twenty centimeters from the rear wall.

    Abstract: A system, for use in evaluating operation of a vehicle, includes a hardware-based processing unit, and a non-transitory computer-readable storage component including various functioning modules. The modules in various embodiments include an input module that, when executed by the hardware-based processing unit, receives, from a vehicle-braking sensor, braking data indicting characteristics of a braking event at the vehicle. The system in some implementations includes an input unit receiving the braking data from the sensor and passing it to a braking-monitoring module. The braking-monitoring module, when executed by the hardware-based processing unit, determines, based on the braking data, whether the braking event is within an acceptable pre-established limit. The technology in various embodiments includes processes performed by the system and algorithms used therein.

    Abstract: A thermal conditioning system for an inductive charging system. An open enclosure charging unit includes at least one surface generating an electromagnetic field for inductively charging a portable device. A primary conduit coupled to the open enclosure charging unit. The primary conduit outputs conditioned air to the open enclosure charging unit. The conditioned air output by the primary conduit maintains a temperature of the portable device at a predetermined temperature range within the open enclosure charging unit.
