  • Publication number: 20190322128
    Abstract: A vehicle wheel assembly includes a vehicle wheel including a wheel body having a center. The vehicle wheel defines a plurality of openings arranged annularly around the center of the wheel body. The vehicle wheel assembly further includes a self-deployed wheel shutter system coupled to the vehicle wheel. The self-deployed wheel shutter system includes a hub plate, an annular rim disposed around the hub plate, and a plurality of shutter flaps. The shutter flaps are movable relative the vehicle wheel between an extended position and a retracted position. In the extended position, the shutter flaps cover the openings of the vehicle wheel to preclude air from flowing through the vehicle wheel. When the plurality of shutter flaps are in the retracted position, the openings are exposed, allowing the air to flow through the openings of the vehicle wheel.

  • Publication number: 20170369069
    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.
