Abstract: A method produces at least one defined connecting layer between two components, wherein the first component is produced from a first metallic material and the second component is produced from a second metallic material and the first and/or second component has a coating of a third metallic material, the melting temperature of which is lower than the melting temperature of the first and second materials. In this case, the coating of at least one of the components is heated locally to a connecting temperature, which lies above the melting temperature of the third material and lies below the melting temperature of the first material and below the melting temperature of the second material, and is cooled down in order to form a defined connecting layer when the coating solidifies.

Abstract: A method for determining an operating temperature of a battery cell in which (i) a value of a measure variable for determining an external temperature of the battery cell is detected, (ii) an internal temperature of the battery cell is determined by detecting an electrical impedance of the battery cell, and (iii) a value of the operating temperature of the battery cell is determined from the external and/or the internal temperature. The internal temperature of the battery cell in a first operating state of the battery cell is determined more frequently when the value of the determined external temperature, the internal temperature and/or the operating temperature lies within a predefined first safe range, and is determined less frequently when the value of the determined external temperature, the internal temperature and/or the operating temperature lies outside the predefined first safe range.

Abstract: A profile strut includes an upper chord, a lower chord, two spaced-apart lateral walls which, together with the upper chord and the lower chord, define an interior, and a first profile end and a second profile end. A first end piece is disposed in the first profile end and a second end piece is disposed in the second profile end. A connecting web connects the first end piece to the second end piece. Each of the first end piece and the second end piece bears via end faces thereof against adjacent inner wall regions of the upper chord and the lower chord; respectively. An intermediate region, which is configured as a tunnel incorporated into the lower chord, is disposed between the first profile end and the second profile end.

Abstract: An energy absorption device for a bumper of a motor vehicle has a first deformation element on the front side of the bumper. The first deformation element is a foam shaped part which extends over the width of the bumper and has a density of from 20 to 50 g/l. At least one second deformation element, with a density which is at least 50 g/l higher than the first deformation element, is inserted into the first deformation element.

Abstract: An air flap system for controlling the intake of air into a motor vehicle includes at least one air flap which can be pivoted between an open position and a closed position, and an elastic element which is provided to couple the air flap system to a vehicle frame. The elastic element is elastic at least partially along the longitudinal direction of the vehicle.

Abstract: A method operates a visual field display device, in particular for a motor vehicle, which is designed to produce a projection light beam with a display content and to project the display content onto a partially transparent reflecting projection screen, in particular a front window of the motor vehicle, such that a virtual display image which is superimposed into a field of vision of a user is generated behind it. The method determines image element edges having vertical or a vertical component in the virtual display image to be superimposed and tilts the image element edges thus determined to a respectively adapted tilt angle with respect to the vertical, such that double images of the respective image element edges in the virtual display image are offset with respect to each other in the horizontal direct for the user due to double reflections of the projection light beam on two optical boundaries of the projection screen and appear substantially sharp.

Abstract: A motor vehicle has at least two drive motors, at least one drive motor being an electric machine; a high-voltage accumulator; and an automatic gearbox, having at least one fixed transmission ratio and at least one power-split transmission ratio for transmission regulation starting from the at least one fixed transmission ratio. The motor vehicle further includes an electronic control unit, which is designed such that, when a gear change command is present, the shifting element to be opened of the fixed transmission ratio to be disengaged is unloaded in a torque-controlled manner by at least two of the drive motors. For the shifting element to be opened, the torque load is calculated and observed. The torque load is observed with the objective of bringing about a load change by way of a zero crossing in order to produce a no-load state at the shifting element.
