Abstract: Restraining a spare wheel in a vehicular floor recession during a vehicle rear impact event is accomplished by securing a connection member from a first anchoring location outside of the recession to a second location within the floor recession. The spare wheel lies in the recession and a threaded bolt attached to the floor under the spare wheel passes through the center hole of the spare wheel. The threaded bolt also passes through a spare wheel holding plate that resides on the spare wheel hub to distribute a holding force from the plate to the circumference of the hub created by screwing a threaded wing nut onto the bolt passing through the holding plate. Since the belt passes from the wheel center to a location outside of the wheel's perimeter, the wheel and tire are securely restrained during the transmission of forces during a vehicular rear impact event.

Abstract: A method of vehicle suspension testing includes conducting actual road testing of a vehicle including collecting data, and generating a drive file from the collected data for road test simulation. A vehicle suspension parameter is changed to result in a changed vehicle. Initial simulated road testing of the changed vehicle is conducted using the drive file, and results from the simulated and actual road testing are compared using acceptability criteria to determine whether to conduct further actual road testing of the changed vehicle before conducting further simulated road testing of the changed vehicle in response to the changed suspension parameter. Further simulated road testing of the changed vehicle is conducted if the acceptability criteria are met. Otherwise, further actual road testing of the changed vehicle is first conducted to develop a new drive file for use with additional simulated road testing of the changed vehicle.

Abstract: This invention relates to a sun gear member and sun gear shaft providing improved manufacturing time and material cost savings. This invention further relates to the packaging of a compact electro-mechanical transmission specifically as it pertains to the redesign of the planetary gear arrangement to compensate for the new design of the sun gear member and sun gear shaft. Several design modifications are disclosed in order to reduce the diameter of the planetary gear arrangement and its inclusive members. For example, the ring gear is chamfered to allow for additional clearance so that the planetary gear arrangement and the electronic motor package can be more compact when sun gear has separable sun gear members. In addition to packaging considerations, material costs, fatigue life requirements, and manufacturability of relevant transmission components were governing concerns in the redesign of the sun gear member and sun gear shaft.

Abstract: A bolt lock locks a bolt against rotation on an output gear. The bolt lock includes a locking plate having a ring-shaped body encircling the head of the bolt and provided with locking tabs bendable into locking engagement with the flat sides of the bolt head to prevent the bolt from rotating. The plate is secured to the output gear by additional bolts. The ring-shaped body has additional locking tabs bendable into locking engagement with the flat sides of the heads of the additional bolts.

Abstract: A system for generating hydrogen gas for use in a fuel cell includes a powder metal hydride source, a water source, a mixing device and a catalytic hydrogen generating chamber. A method of generating hydrogen for use in a fuel cell includes the steps of: providing a source of dry metal hydride fuel; providing a source of steam; providing a mixing/reaction chamber connected to the source of dry metal hydride fuel and to the source of steam; operating the mixing/reaction chamber to transport the dry metal hydride fuel from its source to a byproduct receptacle and feeding steam into the mixing/reaction chamber such that the steam reacts with the dry metal hydride fuel to produce hydrogen gas and a dry metal powder byproduct; removing the dry metal powder byproduct from the mixing/reaction chamber; and extracting the hydrogen gas from the mixing/reaction chamber.

Abstract: A residual ratio factor characterizing the amount of residual exhaust gas left in a selected cylinder at the end of a piston intake stroke is determined from tabular and surface models based on previously gathered dynamometer data from a test vehicle at various engine speeds. The residual ratio factor is then used to calculate the mole fractions of air and residual exhaust gas in the selected cylinder, which, in turn, are used to determine mass airflow at an engine intake port at the end of the intake stroke. The mass airflow can then be used to derive further models for determining an engine operating parameter, such as fuel/air ratio, required for achieving at preselected vehicle operating condition.

Abstract: An automatic transmission for a vehicle includes an input shaft, an output shaft, a first and second plurality of gears, and a series of engagement elements. The series of engagement elements includes at least one overrunning engagement element in mechanical communication with the second plurality of gears.

Abstract: A system for designing vehicle chassis carriers comprises a user interface that receives vehicle parameter data. The user interface may be implemented using a spreadsheet or other data entry application as are known in the art. A user enters the vehicle parameter data such as vehicle dimensions and geometry. A design program such as a CAD program receives the vehicle parameter data and generates a vehicle chassis carrier design according to the vehicle parameter data and design constraints. The design constraints include weights, structural strength, and clearance information with respect to the carrier, the vehicle chassis, and obstructions in the environment.

Abstract: A dual-sectioned automotive propeller shaft features a weakened area in a first section. Under an axial load, the first section buckles transversely to a longitudinal axis of the shaft to absorb substantially all of the energy exerted against the shaft. A second section of the shaft is thereby isolated from consequences of the axial load enabling its placement and proximity to other components mounted to the undercarriage of the vehicle.

Abstract: A vehicle component test method includes measuring first acceleration data at discrete locations on a first vehicle frame during an actual road test of a first vehicle and measuring second acceleration data at the discrete locations on a second vehicle frame of a second vehicle mounted on a test fixture. The second acceleration data is compared to the first acceleration data and an acceleration error is generated. The test fixture is adjusted based on the acceleration error until the acceleration error is within a predetermined range.

The system compiles marketing data from a plurality of internal and external data sources into a centralized database. Internal and external sources include legacy systems. Data in the centralized database is distributed to a plurality of client venues by using an extract engine to extract a subset of data from the centralized database and creating a venue specific database. Access to the venue specific database is facilitated by use of a application programmers interface for allowing the development of applications for venue specific use of the venue specific database. Both the compilation and distribution process is performed on a periodic basis to provide timely, accurate, and consistent marketing data across the plurality of client venues.
