Patent number: 7247112Abstract: 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.Type: GrantFiled: February 17, 2005Date of Patent: July 24, 2007Assignees: GM Global Technology Operations, Inc., DaimlerChrysler AG, DaimlerChrysler CorporationInventors: Michael D.

Patent number: 7243981Abstract: 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.Type: GrantFiled: June 3, 2005Date of Patent: July 17, 2007Assignee: DaimlerChrysler CorporationInventors: Sae U Park, Madhu R Koka

Patent number: 7244905Abstract: 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.Type: GrantFiled: June 9, 2005Date of Patent: July 17, 2007Assignee: DaimlerChrysler CorporationInventors: Manohar Das, James W.

Patent number: 7240906Abstract: 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.Type: GrantFiled: December 4, 2003Date of Patent: July 10, 2007Assignee: DaimlerChrysler CorporationInventor: Gerard Klees

Patent number: 7240544Abstract: 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.Type: GrantFiled: December 22, 2004Date of Patent: July 10, 2007Assignee: DaimlerChrysler CorporationInventors: Jean P Mallebay-Vacqueur, Mitchell Puskarz
