  • Method for operating the drive train of a motor vehicle
    Patent number: 7442148
    Abstract: In a method for operating a motor vehicle in the event of a shift of a power divider actuated by external force, before the commencement of the shift of the power divider, a control device reduces the torque at the shifting members involved in the shift. The vehicle transmission is an automatic transmission, and the reduction is achieved a clutch in the automatic transmission is opened. After the conclusion of the shift, a torque is permitted again at said shifting members, and the clutch is closed again. The vehicle driver can consequently execute a shift in the power divider merely by triggering a shift requirement.

  • Supporting structure for a motor vehicle
    Patent number: 7441829
    Abstract: A supporting structure for a motor vehicle which, at a front end of a safety passenger cell, is provided with a front section with a crumple zone and two wheel housings which are arranged laterally in the region of the crumple zone and in which a respective wheel having a tire and a wheel rim, is arranged. A wheel support ramp which runs obliquely downward, as seen from the travel direction, is formed and causes the respective wheel, which has been moved toward the wheel support ramp as a consequence of a crash-induced deformation of the crumple zone, to be guided downward in the direction of the safety passenger cell. An additional wheel impact element is provided for each wheel and is deformable by the respective wheel (3) that has been moved as a consequence of the crash-induced deformation of the crumple zone.

  • Rolling-code based process and system
    Patent number: 7443280
    Abstract: In a rolling-code based process and system for the unambiguous identification of serial numbers in a data communication system, least two subscribers each have an identical serial number set. The process includes a) the first subscriber transmitting a first challenge with respect to a serial number from the serial number set to the second subscriber; b) subscriber responding the second subscriber by a first response corresponding to the first challenge; generating an identification signal for the second subscriber which unambiguously identifies the second subscriber with respect to the first subscriber if the first response corresponds to the serial number expected on the basis of the first challenge of the first subscriber.

  • Method of operating an internal combustion engine
    Patent number: 7438045
    Abstract: In a method of operating an internal combustion engine with a switch-over capability between a compression ignition mode of operation and a spark ignition mode of operation in higher load ranges which includes a cam-operated valve drive with a valve control providing, in the compression ignition mode of operation, for an increased valve overlap of the valve opening times, smooth engine operation and optimal exhaust gas emissions are obtained also during rapid load changes upon changing the engine operating mode as the change-over is accompanied by changes of the injection parameters, the throttling parameter and the valve control, which are coordinated with respect to one another as the valve control is switched over by changing the amplitude and phase position of the valve stroke of at least one of the inlet and outlet valves.

  • Finite element simulation
    Patent number: 7440879
    Abstract: A method for automatic evaluation of a finite element simulation for an industrial system such as a motor vehicle body includes predefining an electronic design model of the industrial system and generating finite elements for the model. The stresses occurring in the finite elements are determined using a finite element simulation. Each finite element, which is a two-dimensional element and not a rigid object element and whose stress exceeds a predefined stress limiting value, is determined. For each determined two-dimensional element which is not a triangle, an element limiting value is determined on the basis of the stress limiting value. Each determined two-dimensional element is classified as critical if its computed stress exceeds the established element limiting value.

  • Loudspeaker System for Motor Vehicles Utilizing Cavities Formed by Supporting Structures
    Publication number: 20080247564
    Abstract: In order to produce a powerful bass, bass boxes require a relatively large installation volume, for which insufficient space is frequently available in the interior of a motor vehicle, in particular in a passenger motor vehicle. When drivers and front-seat passengers require the sound installation to have a powerful bass, a bass box requires a volume in the order of magnitude of at least 10 to 15 liters. In order to restrict the physical space which is required for this purpose in the vehicle interior, the active sound transducer of the loudspeaker system is acoustically coupled on its rear face to a resonant area which is formed at least in parts by the cavity within a supporting structure of the vehicle.

  • Core-shell particles having non-polar outer surface and methods for producing a three-dimensional object from the particles
    Patent number: 7431987
    Abstract: The invention relates to particles for producing a three-dimensional object by using layer-building methods (powder-based generative rapid prototyping methods), to methods for producing a three-dimensional object therefrom, and to an object that can be produced by using the particles or the methods. The aim of the invention is to improve the precision of production methods of this type by preventing the tendency of the particles used to agglomerate. To this end, a surfactant layer is applied, whereby the nonpolar groups of the surfactants are oriented toward the particle surface thus forming a hydrophobic surface having a low tendency to agglomerate.

  • Method and apparatus for detecting an object in a motor vehicle environment
    Patent number: 7432490
    Abstract: A method for detecting an object in a motor vehicle environment uses a detection means which scans the environment at predetermined angular increments ?i+??i (i=1,2, . . ., N). When sensing a reflection signal of the object at an angle ?i, the angular increments are refined in the angular range between the adjacent angles ?i?1 and ?i+1 as a function of signal propagation times ti?1, ti and ti+1 of the reflection signals sensed at the angles ?i?1, ?i and ?i+1.
