  • Patent number: 10293680
    Abstract: A method and apparatus are provided to reduce the overall weight of a rear differential cooling system of a motor vehicle. The apparatus includes a body panel system. That body panel system includes (a) a rear diffuser, having a front air inlet, (b) an underbody panel, overlying the rear diffuser as well as (c and d) first and second air tunnels formed between the rear diffuser and the underbody panel, and (e) a rear valance, including first and second vent openings for discharging air received from the first air tunnel. A heat exchanger is provided between the air tunnels and the vent openings. A related method for improving weight distribution and reducing overall weight of a rear differential cooling system is also provided.

  • Publication number: 20190105943
    Abstract: A method and system for improving the strength, functionality and wear-resistance of a composite hybrid wheel is disclosed. Each spoke may define an airfoil shape and have a secondary wing-like extension attached thereto to generate airflow past the vehicle brakes during vehicle operation. Alternatively, the spokes may be shaped in cross-section as either an I-beam or an H-beam configuration. Customer-interchangeable wheel inserts formed from a reinforced polymerized material, such as a long carbon fiber reinforced composite, are strategically attached to one or more of the spokes. The inserts are used to enhance the aesthetic appeal of the wheel, increase its structural integrity and provide easy interchangeability in the event of damage. A faux bead composite lock ring also formed of a reinforced polymerized material such as a long carbon fiber reinforced composite can be attached to the wheel spokes to cover the composite rim flange.

  • Patent number: 10252594
    Abstract: Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments, the ride height sensing system includes a self-calibration system including at least one Hall effect sensor mounted at a fixed distance and orientation with respect to the electromagnetic source to provide for continuous calibration of the system. In one embodiment, the enhanced ride height sensing system includes at least two inertial measurement units, such as accelerometers mounted to each of the body frame of the vehicle and the axle frame of the vehicle. This enables the system to optimize power usage by more accurately and efficiently measuring the ride height at high frequency rates with relatively lower power consumption.

  • Publication number: 20190035174
    Abstract: Method and apparatus are disclosed for vehicle calibration based upon performance product detection. An example vehicle includes a receiver to receive a wireless signal from a transducer of an performance product that includes characteristics of the performance product. The example vehicle also includes a product controller to authenticate the performance product based upon the wireless signal and send, upon authentication, a calibration instruction that includes the characteristics. The example vehicle also includes an electronic control unit to receive the calibration instruction and adjust a calibration to a target setting based upon the characteristics.

  • Publication number: 20180308299
    Abstract: A system includes a processor configured to receive a track-creation request. The processor is also configured to initiate track recording, responsive to the request and record GPS points corresponding to vehicle movement. Further, the processor is configured to receive a track-completion instruction and store the recorded GPS points, and a line connecting the points, as representing a recorded track.

  • Patent number: 9925840
    Abstract: Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments of the present disclosure, a band pass filter is used for signal processing of the encoded electromagnetic data. Additionally, several Hall Effect sensors may be used with a single electromagnetic source to provide multi-axis sensing and as such, provides robustness in determining ride height changes, or in the case of dependent suspensions (solid axle), a single electromagnetic source can used to determine ride height at multiple locations on the axle.
