Abstract: A multiple speed power transmission, comprising an input shaft; a transmission case; a co-planar gear set; a rear epicyclic gearing assembly with four rotating members; a first clutch connecting the output of the co-planar gear set to the fourth rotating member; a second clutch connecting the output of the co-planar gear set to the first rotating member; a third clutch connecting the input shaft to the third rotating member; a first brake holding the fourth rotating member against rotation; a second brake holding the third rotating member against rotation; and an output shaft connected to the second rotating member.

Abstract: A method for simulating a hydroforming process includes modeling a virtual hydroforming die and a virtual tubular workpiece. The virtual workpiece is placed within the die after the die has been expanded. The die is then contracted to a finished size while the workpiece is deformed into a non-circular cross section in contact with the virtual die. The workpiece is subsequently pressurized to simulate production of a finished part.

Abstract: Generally provided is a system and method that determines a force-travel profile of a shifter in a vehicle having a shifter having an associated shifter shaft for a transmission. The feel of the shifter to a user of the shifter may be improved by using present system. Additionally, accurate measurements for determining shifter forces applied to a shifter and corresponding position of the shifter are performed. In operation, the system correlates the forces applied to the shifter and associated movement of the shifter to determine an associated feel of the shifter. The system operates to equate the forces correlating to the shifter and movement of the shifter to calibrate a feel of the shifter for a user applying the force to the shifter to actuate the shifter.

Abstract: A high-voltage energy regulated conversion circuit (HVERCC) (12) for coupling to a vehicle bus (24) includes a battery bus (28) and a heater bus (29). A high-voltage battery pack (30) is electrically coupled to the battery bus and a resistive load element (42) is electrically coupled to the heater bus (29). A high-voltage energy converter (HVEC) module (22) is electrically coupled to the vehicle bus (24), the high-voltage battery pack (30), and the resistive load element (42). The HVEC module regulates power on the vehicle bus (24), the battery bus (28), and the heater bus (29) and operates in multiple functional modes including a constant voltage mode, a constant current mode, and a constant battery current mode.

Abstract: The present invention provides an integrated tailgate for a vehicle having a planar cargo bed, the tailgate operable between a closed vertical position and an open horizontal position, and a structure slideably received by the tailgate extendable to a substantially horizontal position when the tailgate is in the open position, whereat the structure is rotateably operable between the horizontal position, an upwardly rotated substantially vertical position perpendicular to the open tailgate, and a downwardly rotated position a predetermined degree between zero and ninety degrees.

Abstract: A rollover sensing system (12) that may be used in the determination of when to deploy restraints in the vehicle. The rollover sensing system (12) may include lateral acceleration sensors (32), a roll rate sensor (18) and a roll angle detector (20). A control circuit (16) determines a predetermined rollover threshold in response to the roll rate and roll angle detector (20) and calculates an adjusted threshold as a function of the predetermined rollover threshold and the lateral acceleration. The control circuit (16) generates a control signal in response to the adjusted threshold.

Abstract: A fuel pump has a pump cover with an inlet through which fuel from a fuel tank is drawn by an impeller to a pumping chamber formed by a pump bottom and the pump cover. The inlet has divergent sides oriented such that fuel being pumped is routed radially outward of primary vortices in a section of the pumping chamber adjacent the inlet to a section of the pumping chamber opposite the inlet. In a first embodiment, the upper side of the inlet is oriented at approximately a 10 to 12 degree angle from the lower side. In a second embodiment, the upper side is oriented at approximately a 127 degree angle from a line parallel the shaft rotation, and the lower side is oriented at approximately a 139 degree angle from the same line.
