The wind deflector (13) is transferred into a second operative position (WS2) and the rear air-guiding device (16) is transferred into a second lifting position (HS2) above the first lifting position (HS1) if the roof arrangement (10) is open and if the driving speed (VF) is above a predetermined, second value (V2).

Abstract: A folding-top compartment lid is held on a mounting support which can be moved into an open and a closed position by opening levers. To lock the folding-top compartment lid, locking hooks are provided, and these can be activated along with the opening levers in accordance with the control of the latter.

Abstract: A connection connecting two tool parts includes a first tool part and a receptacle for receiving a second tool part. A clamping device clamps the tool parts together in a joined state. The connecting point further includes a retaining device that is independent of the clamping device and holds the tool parts together in the joined state.

Abstract: An ultrasound system for the generation of low-frequency high-power ultrasound includes a resonator for transmitting the ultrasound to a medium. To safely handle the ultrasound system, the ultrasound system has a light source illuminating a workspace of the ultrasound system.

Abstract: A vehicle structure includes a composite supporting structure made of a substantially electrically non-conducting composite material and at least one ground connection line. The ground connection line is integrated into the composite supporting structure.

Abstract: A convertible has at least one rollover protective structure, in particular a roll bar, which is extendable through an opening which is closable by a covering. In order to further optimize the opening movement of the covering during the extension of the rollover protective structure of the convertible, the covering is attached to a bodywork part with the aid of a multi-bar linkage which controls the opening movement of the covering.

Abstract: An exhaust system for an internal combustion engine, having a first exhaust tract assigned to a first group of cylinders of the internal combustion engine, and having a second exhaust tract assigned to a second group of cylinders of the internal combustion engine, each exhaust tract comprising an exhaust gas purification device, a first silencer arranged on the outlet side of the respective exhaust gas purification device, and a second silencer arranged on the outlet side of the respective first silencer. Each exhaust tract includes a bypass line, it being possible for exhaust gas to be diverted via each bypass line, starting from the respective first silencer, bypassing the second silencers, and the bypass lines and hence the first silencers of both exhaust tracts being connected to one another by a mixing line.

Abstract: The invention relates to a hybrid drive-train of a motor vehicle (1) equipped with a mechanical all-wheel drive, said drive-train comprising a combustion engine (5) which can be drive-connected to two axles (5) by means of a transmission (6), and a transversally installed electric machine arrangement (10). In order to improve the hybrid drive-train, particularly with regard to an operational mode that is highly dynamic, the electric machine arrangement is arranged approximately central in relation to the transverse direction of the vehicle.

Abstract: A method is provided for controlling a brake system of a motor vehicle having a brake device (40) with a hydraulic brake unit (41) and a recuperation brake unit (42). The method includes calculating (S1) a hydraulic brake force characteristic curve (B2) of the hydraulic brake unit (41) on the basis of at least one detected characteristic of the brake system, selecting (S2) a generator-based brake force characteristic curve (G1-G4) of the recuperation brake unit (42) on the basis of a predefined criterion and as a function of the calculated hydraulic brake force characteristic curve (B2), and controlling (S3) the hydraulic brake unit (41) and the recuperation brake unit (42) in accordance with a detected degree of actuation of the brake pedal (10), the calculated hydraulic brake force characteristic curves (B2), and the selected generator-based brake force characteristic curve (G1-G4).

Abstract: An actuating device for an automated dual clutch transmission of a motor vehicle drivetrain in manual-shift mode includes first and second shift elements disposed in a region of a steering column, the first shift element being configured to effect an upshift and the second shift element being configured to effect a downshift of the dual clutch transmission. Simultaneous operation of the shift elements is configured to effect idle operation of an engine with at least one open transmission clutch. The idle operation is present only while the first and second shift elements are actuated. The shift elements are configured to transmit a torque via a closed transmission clutch when at least one of the shift elements is released. A control device is configured to initiate rotational speed adaptation of the engine as a function of an actuation of the first and second shift elements.
