Abstract: In an accident assistance system for a motor vehicle having an accident detector for detecting an accident and an assistance device for indicating escape measures and emergency measures in response to the detection of an accidents, instructions which are output by the assistance device are printed on an information carrier which is ejected when an airbag is triggered in the event of an accident. The instructions concerning escape measures and emergency measures are advantageously printed onto the airbag.
Abstract: An exhaust-gas purification unit for purifying the exhaust gas from an internal combustion engine which is preferably operated in lean-burn mode, in particular a diesel engine used in motor vehicles, has a particulate filter and a SCR catalytic converter arranged in the exhaust pipe in succession in the direction of flow, and a reducing-agent supply. Ammonia can be added to the exhaust gas from the internal combustion engine on the entry side of the SCR catalytic converter by the reducing-agent supply. The exhaust-gas purification unit includes a hydrogen-generating unit for enriching the exhaust gas from the internal combustion engine with the hydrogen which it generates.

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.

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.
Abstract: In a sealing arrangement, e.g., for sound-insulating sealing of a gap between a windscreen of a vehicle and instrument panel, a first sealing element is arranged between the instrument panel and the windscreen, below the first sealing element a second sealing element is arranged between the windscreen and a base component, the sealing arrangement including openings through which air may flow into a passenger compartment of the vehicle. As a result, both a defrosting of the wiper system and also sound insulation may be provided.
Abstract: A steering assembly has a bracket fixed to a vehicle and a bracket carriage displaceably arranged on the bracket. The assembly can be reliably collapsed in the event of an accident and is simple and cost-effective to manufacture. The bracket carriage is attached to the bracket by way of an attachment embodied in one piece with the bracket and/or the bracket carriage.

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.
Abstract: A headrest of a motor vehicle seat can be folded down into an inoperative position. The headrest has a headrest body and a headrest bracket which are mechanically connected in such a manner, via a bearing part having a sliding bearing and a pivot bearing that a vertical displacement and a pivoting about a horizontal pivot axis arranged perpendicularly to the longitudinal axis of the vehicle are achievable.

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.
Abstract: In a method, a steeringwheel torque for the steering wheel of a motor vehicle is determined. In this context, a steering angle for steered wheels is predefined by the driver by means of the steering wheel. A steering torque which represents the forces on the vehicle axle acts on the steering wheel. A desired manual torque (M_soll) is determined here using at least one axle model. The desired manual torque is then superimposed on the actual steeringwheel torque (M_ist).

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.

Abstract: A method for operating a four stroke internal combustion engine in which the combustion position can be set/controlled/corrected. The phase position of intake and/or exhaust phase is shifted for this purpose. Compression ignition takes place at part-load, and spark ignition takes place at full load. In the event of a load change in the part-lead range, the theoretical shift in the combustion position is compensated by the shift in phase position of the intake and/or exhaust phase.
