Abstract: A method and apparatus for efficiently cooling and lubricating rotating components in a hybrid transmission is provided. By efficiently managing cooling flow to and between the rotating elements, flow requirements and associated pumping requirements within the drive unit are minimized. In addition, by providing a method for placing the fluid directly on the required components, spin losses associated with component contact with stray oil are reduced. Combined, the reduction in pumping and spin losses create a more efficient drive unit and an overall more efficient hybrid drive system which directly leads to higher fuel economy.

Abstract: A vehicle body assembly including a portion that is subject to deformation during vehicle impact events includes a body component, and at least one deformation control plate carried by the vehicle body assembly to engage the body component and inhibit deformation of the body component beyond a threshold amount. The deformation control plate is arranged to engage with the frame component only when the frame component is deformed beyond a first amount. Further deformation of the frame component bends or otherwise deforms the deformation control plate which provides a force resisting further deformation of the frame component and also dissipates the kinetic impact energy away from the deforming area of the frame component.

Abstract: A method for estimating weld nugget diameter includes receiving current and voltage inputs, a time input, and a force input. In certain embodiments, the method also uses other weld parameters including type of material, type of stack, stack thickness, applied force, preheat current, RMS value of weld current, weld level, and weld time. The method further determines a resistance curve based on the current and voltage inputs, and time input. It also derives parameters from the resistance curve, and determines a weld nugget diameter estimate based on both resistance parameters.

Abstract: A retainer for a vehicle cargo area that is bounded in part by a floor and a door moveable between open and closed positions includes a retaining member spanning at least a portion of the cargo area, a pivot feature operably associated with the retaining member, and a retaining feature that yieldably retains the retaining member in its second position to facilitate retaining cargo within the cargo area. The retaining member pivots about the pivot feature relative to the cargo area between a first position and a second position wherein the retaining member is inclined relative to the floor of the cargo area. When the door is open the retainer is normally in its second position to facilitate retaining cargo within the cargo area.

Abstract: A hydro-pneumatic suspension system for a vehicle includes hydraulic struts selectively interconnected, in on-road and off-road configurations, to obviate the need for conventional shocks and springs. In the on-road configuration, the hydraulic struts are linked cross-vehicle with multiple accumulators in the circuit for increased on-road roll stiffness. In the off-road configuration, the hydraulic struts are self-linked, with fewer accumulators, to maximize flexibility and articulation of the system. The system also includes a hydraulic supply to selectively raise and lower the vehicle for the off-road and on-road configurations, respectively. In a further configuration, the roll stiffness and articulation of the suspension system is configured solely by the selective connection of accumulators to the hydraulic suspension circuit.

Abstract: An aerodynamic noise measurement system for a vehicle uses sound reflectors to determine the sound wave propagation of aerodynamic noise of the vehicle. The vehicle is placed within a test section of a wind tunnel. The air flow of the wind tunnel generates the aerodynamic noise as it passes over the vehicle. An array of sound reflectors is placed outside of the air flow of the wind tunnel. Microphone arrays receive the aerodynamic noise directly from the source and from the sound reflectors. An analyzer system forms an acoustic image of the vehicle based on the aerodynamic noise. A viewing device displays an image of the vehicle with an overlay of aerodynamic noise data in real-time.

In one presently preferred implementation, the pivot connector is connected to the seat back and the entire seat may be pivoted about the pivot connector to move the seat relative to and preferably into a forward or a rearward area in the vehicle interior. The slide permits sliding or generally horizontal movement of the seat in the vehicle and the seat may be pivoted and/or moved into a variety of positions.
