Abstract: An airbag for a motor vehicle, comprises a support structure that can be displaced from a storage position to a restraint position, and a covering which surrounds a restraint volume of the airbag formed by the support structure in its restraint position. At least one connecting element, which extends inside the restraint volume, connects together the hollow bodies of the support structure and/or the surface areas of the covering.

Abstract: An operating method is provided for a motor vehicle diesel engine having an exhaust emission control system that includes a three-way catalytic converter and an SCR catalytic converter situated one behind the other in the flow direction of the exhaust gas. The diesel engine is operated, at least intermittently, with an air-fuel ratio of approximately ?=1.0 in a first operating range in which the SCR catalytic converter falls below a predefinable minimum temperature and with excess air that is typical for normal diesel engine operation in a second operating range in which the SCR catalytic converter exceeds the predefinable minimum temperature. An output signal of an exhaust gas sensor situated downstream from the three-way catalytic converter and which is correlated with a NOx concentration of the exhaust gas is used to set the air-fuel ratio in the first operating range.

Abstract: The invention relates to a method for the production of motor vehicles, in particular personal motor vehicles, wherein a plurality of moveable outer skin elements (90) forming the outer skin of the motor vehicle, in particular doors (74), hoods (76) or hatches (78), are applied to a respective shell (42) of the motor vehicle, wherein the moveable outer skin elements (90), in particular the doors (74), hoods (76) or hatches (78) are only applied to the respective shell (42) of the motor vehicle in or after an assembly line, in particular in or after a main assembly line (46). Moreover, the invention relates to a motor vehicle, in particular a personal motor vehicle, having a shell (42), which has a cathodic dip coating or similar corrosion protection coating added to it and to which a plurality of outer skin elements (90, 80) forming the outer skin are applied, wherein the shell (42) of the motor vehicle only has the cathodic dip coating or similar corrosion protection coating added to it.

Abstract: In a group transmission device comprising a splitter group transmission unit and at least one active actuating unit for introducing an actuating torque into the splitter group transmission unit, an open- and/or closed-loop control unit is provided for adapting the actuating torque introduced into the splitter group transmission unit to at least one synchronized shifting operation to be executed by means of the splitter group transmission unit without synchronizing ring.

Abstract: In a method for controlling shifting in a motor vehicle having an internal combustion engine and an automatic transmission, intermediate gas is automatically applied for reducing and/or compensating for an abrupt shift when downshifting. In a first phase, wherein the transmission is in the hydraulic down time thereof, the actual torque provided by the engine is slowly increased, until a torque required by the transmission is achieved. Subsequently, in a second phase, wherein the actual torque of the engine is less than the target torque, a throttle valve is opened further. In a subsequent third phase, in which the actual torque of the engine has achieved the target torque required for synchronization, a late ignition angle is set.

Abstract: A device and a method for checking the leak-tightness of an electrochemical energy store includes a detection unit that can detect a gas concentration in a battery housing that is closable. The detection unit is a metal oxide sensor connected to an evaluation unit, and as a function of the detected gas concentration a control signal is automatically generated by the evaluation unit for disconnecting the electrochemical energy store and/or for triggering a binder release unit.

Abstract: A valve mechanism for a gaseous medium of an airbag is provided. The valve mechanism includes a first and second layer, which respectively include a passage opening that is substantially closed in a closed position of the valve mechanism by a corresponding cover region of the other respective layer. An adjusting element in the form of a tube with an adjustable volume provides a temporary passage position of the valve mechanism by lifting one of the cover regions of the corresponding layer from the corresponding passage opening.

Abstract: The invention proceeds from an on-board diagnosis unit for a motor vehicle for detecting a released mechanical connection between at least two fluidic lines (10, 11), having at least one first contact element (12, 13, 14) and at least one second contact element (15) which is spaced apart axially, of which contact elements (12, 13, 14, 15) at least one is provided for being deformed at least substantially elastically for making contact with at least one connecting point (16, 17, 18) of the mechanical connection. It is proposed that the on-board diagnosis unit has at least one third contact element (12, 13, 14) which is arranged spaced apart axially from the second contact element (15).
