    Abstract: Customizable methods of protecting select regions of a light metal or alloy workpiece, such as a wheel (10), from corrosion are provided. The light metal or alloy may be magnesium, aluminum, or titanium. A first region (50) of the exposed surface (40) is identified that has increased exposure to corrosive agents in an external environment (in service conditions) as compared to a second region (52). Thus, a corrosion resistant coating is selectively formed over the first region (50) of the exposed surface (40). The second region (52) may have a second distinct corrosion resistant coating. Methods for selectively and efficiently forming such corrosion resistant systems are provided. In certain methods, the locations where the corrosion resistant coating is applied are controlled by immersing only select portions of or selectively masking the workpiece in a micro-arc oxidation electrolyte bath. In other methods, the thicknesses of the coatings are locally tailored by controlling the electric field.

The power take off control module, having instantaneous data regarding the pressure applied to the hydraulic operator achieves two important operating functions: monitoring and feedback.

  • Patent number: 9937842
    Abstract: A floor mat or cargo mat includes a primary surface and a tray recessed from the primary surface. The tray defines a debris volume below the primary surface. An abrasive panel covers the tray. The abrasive panel is substantially contiguous with the primary surface and is porous, such that debris and liquids pass through the abrasive panel into the debris volume of the tray.

  • Patent number: 9937781
    Abstract: Disclosed are shear plates for structurally connecting vehicle chassis front cradles to battery pack support trays, methods for making and methods for using such shear plates, and electric vehicles with a chassis frame having a front cradle coupled to a battery pack support tray by a shear plate. A shear plate is disclosed for connecting a front cradle to a traction battery pack. The shear plate includes an elongated plate body with opposing fore and aft braces connected by opposing starboard and port braces. The fore brace directly mechanically couples to a cross member of the front cradle, whereas the aft brace directly mechanically couples to a support tray of the traction battery pack. The shear plate's elongated body is designed to transmit in-plane and torsional forces received from the front cradle via the fore brace, through the starboard and port braces, to the support tray via the aft brace.

  • Patent number: 9938908
    Abstract: A system according to the principles of the present disclosure includes a pedal position prediction module and an engine actuator control module. The pedal position prediction module predicts a pedal position at a future time based on driver behavior and vehicle driving conditions. The pedal position includes at least one of an accelerator pedal position and a brake pedal position. The engine actuator control module controls an actuator of an engine based on the predicted pedal position.

  • Publication number: 20180095465
    Abstract: Systems and method are provided for controlling a vehicle. In one embodiment, an obstacle management method includes receiving, via sensing devices, sensor data relating to an environment associated with a vehicle, and determining, with the sensor data, the presence of an obstacle that at least partially obstructs an intended path of the vehicle in a first lane adjacent to a second lane and at least partially occludes a view of the second lane by a first sensing device. The method further includes positioning the vehicle with respect to the obstacle to improve the view of the second lane by the first sensing device without significantly obstructing the second lane, determining a second path that circumnavigates the obstacle and rejoins the intended path, and monitoring the opposing lane via the first sensing device to determine when the second path is clear.

  • Publication number: 20180093671
    Abstract: Systems and method are provided for speed management of an autonomous vehicle during a lane change. The method comprises identifying a planned future lane change, identifying the starting position of the future lane change, measuring the travel distance available to complete the lane change, determining the maximum speed for the autonomous vehicle at the lane change starting position based on the travel distance, setting an interpolated speed limit at a plurality of intermediate points between the current position and the lane change starting position, setting a target speed limit at each of the intermediate points by choosing for each intermediate point the minimum of the interpolated speed limit at the intermediate point and any additional speed limit at the intermediate point, and communicating the target speed limit at the intermediate points as speed constraints to a vehicle control module.
