摘要:
A process for operating an internal-combustion engine with a supercharger which can be cut out, and a device for carrying out the process are disclosed. The engine has, aside from the supercharger or compressor which can be cut in or out as desired, an exhaust-gas return arrangement. No exhaust gas can be conveyed back into the intake line when the compressor is cut in and therefore when there is a pressure rise at the cylinder inlet to above atmospheric pressure and above the pressure prevailing in an exhaust-gas line. The return of exhaust gas into the intake line is prevented in such a way that an exhaust-gas return line opens, opposite a supercharger delivery line from the supercharger, into an intake line to the engine. A shut-off member is arranged at this junction so that during suction operation of the engine the shut-off member closes the supercharger delivery line and during supercharging operation the shut-off member closes the intake line, above the supercharger delivery line, and the exhaust-gas return line.

A vehicle is provided that includes, but is not limited to an energy accumulator in an energy accumulator area. The vehicle also includes, but is not limited to a rear axle area having a rear axle frame and a front axle area having a front axle frame. Furthermore, the vehicle includes, but is not limited to interrupted crash load pathways in the vehicle floor area, which are limited to the vehicle passenger compartment. The energy accumulator is situated on a carrier system in the vehicle floor area, the carrier system closing the interrupted crash load pathways of the vehicle between the rear axle frame and/or the front axle frame.

A body structure is provided for a motor vehicle that includes, two side sills running in the vehicle longitudinal direction, between which a floor group is situated, and two rear frame profiles rigidly connected to the floor group, which extend from the floor group to the rear. The body structure has a structure crossbeam running in the vehicle transverse direction, which rigidly connects each of the two side sills and also the two rear frame profiles directly to one another.

A special node is used in a distributed time-triggered cluster. The special node comprises protocol functionality to establish a time base to use in communicating with a plurality of end nodes and to source timing-related frames to the plurality of end nodes in accordance with the distributed time-triggered communication protocol. The protocol functionality establishes the time base without regard to any timing-related frame sourced from any of the plurality of end nodes. In one embodiment, the protocol functionality of the special node is implemented in a low complexity manner. In one embodiment, the cluster comprises a star topology and the special node performs at least one of semantic filtering and rate enforcement. In another embodiment, the cluster comprises a bus or peer-to-peer topology and each end node is coupled to the communication channel using a low-complexity special local bus guardian.

An impact limiting system of a vehicle is provided with a cladding element and bumper substructure. The bumper substructure is spaced apart from the cladding element, and is covered by the cladding element. The bumper substructure is arranged on the vehicle body, and exhibits impact energy absorbing elements. The impact limiting system exhibits an impact force conveying element between the cladding element and bumper substructure.

A seat assembly includes a seat element constituting a component of the seat structure of a motor vehicle seat, a tubular drive element connected pivotably around its longitudinal axis to the seat element that constitutes a component of a displacement arrangement for an adjustable seat part, for example, for a height adjustable seat cushion, as well as a preferably electrically operated weight sensor for the detection of seat occupancy using the weight of a person sitting in the corresponding motor vehicle seat. Through the detection of seat occupancy, it is possible to control various functional groups of a motor vehicle as a function of seat occupancy, such as, for example, automatic occupancy- and/or weight-dependent adjustment of certain seat components as well as the occupancy- and/or weight-dependent deployment of an airbag module.
摘要:
A process and apparatus for locating and identifying electrical lines in which a high frequency carrier wave, modulated with a four-bit, serial binary code, is transmitted down the line. An electro-magnetic detector is used to locate the particular line bearing this modulated wave, permitting identification of the line without having to make actual electrical contact with the line at the point of identification.

A floor structure of a motor vehicle is provided that includes, but is not limited to a mounting for a starter battery in a cross member adjoining wheel arches for rear wheels. The cross member comprises two stiffening webs and is designed tub-shaped between the stiffening webs. Because of this, the starter battery is reliably protected against a crash.

A car body is provided for a motor vehicle that includes, but is not limited to a structural unit including a rear frame structure with a rear axle and mountings for a fuel tank or an electric accumulator. The structural unit is fixed on a bottom plate of the car body. A correspondingly designed rear frame structure makes it possible to selectively equip the motor vehicle for drives with an internal combustion or purely electric drives or hybrid drives.
