Abstract: An exterior door handle system (2) in a motor vehicle has a bearing bracket (11) on an interior side (10) of an exterior door panel (1) and a door handle (12) on an exterior side (9) of the exterior door panel (1). The door handle (12) is mounted from the exterior and penetrates the exterior door panel (1) for mounting in the bearing bracket (11). A unit (19) formed from a lock barrel (20) and a housing (21) for the lock barrel (20) is mounted in the bearing bracket (11) from the interior and is covered on the exterior side (9) of the exterior door panel (1) by a protective cap (24). A locking clip (30) is mounted in the bearing bracket (11) arranged on the interior side (10) and locks both the unit (19) and the protective cap (24) counter to their respective mounting direction.

Abstract: A battery arrangement (1) has at least two battery cell packs (2, 3) arranged in a common battery housing (4). The battery housing (4) has at least one first opening (5) for supplying cooling air and at least one second opening (6) for discharging heated air. The battery cell packs (2, 3) are arranged one above the other and delimit a tunnel (7) therebetween in a height direction. At least one of the first and second openings (5, 6) is arranged substantially at the same level as the tunnel (7). The tunnel (7) is closed at a side facing one of the first and second openings (5, 6) so that air flowing between the first and second openings (5, 6) is channeled through or around the battery cell packs (2, 3).

Abstract: A motor vehicle has at least one illuminating device in a rear region and at least one wind-deflecting device likewise arranged in the rear region. The wind-deflecting device can be activated. According to the invention, the at least one wind-deflecting device is part of the rear illuminating device.

Abstract: A process for monitoring the operation of a system for the aftertreatment of exhaust gas utilizes respective temperature sensors assigned to catalysts in the exhaust gas system. In addition, a sensor for detecting the NOx content in the exhaust gas is assigned to a reduction catalyst. The detected values, or functions thereof, are in each case compared with the definable reference values and when these definable limit values are exceeded, a corresponding defect information is triggered.

Abstract: A motor vehicle transmission which consists of a change-speed transmission and of an axle gear, is made usable by a special configuration and arrangement of the gear-shifting mechanism without modification for front engine and rear engine drive. For that purpose, the shifting rods disposed horizontally one above the other of the individual transmission speeds are operable by way of the shifting fingers of a vertically arranged shifting lever which is pivotally connected with the also horizontally disposed shifting shaft which is inserted into the change-speed transmission housing either at the bottom or at the top.
