Abstract: The disclosure relates to a method for operating a steering system of a motor vehicle. A voltage reserve is determined as a function of a compensation trajectory for a second actuating voltage and as a function of a modulation limit. A first actuating voltage with a fundamental frequency is determined as a function of the voltage reserve. A compensation voltage with a sixth-order harmonic with respect to the fundamental frequency of the first actuating voltage is determined. The second actuating voltage is determined for an inverter as a function of the first actuating voltage and as a function of the compensation voltage.

Abstract: A device for identifying errors in a computer network is provided. The network includes at least one coupling element, which interconnects at least two network subscribers. The coupling element includes a memory for an actual configuration of the coupling element. The coupling element forwards or discards data packets according to the actual configuration. The device has a target configuration for the coupling element, and the device is configured to compare the actual configuration with the target configuration.

Abstract: A method for secure authentication of control apparatuses in a motor vehicle includes sending an authentication request to a control apparatus of the motor vehicle, receiving an authentication response of the control apparatus and checking the received authentication response. If a result of the checking is that the received authentication response is invalid, the method further includes transferring the control apparatus to a fallback mode, where the fallback mode being safe for the purposes of a dependability of the applicable motor vehicle. The authentication response of the control apparatus is provided based on at least part of authenticity information of the control apparatus. The transmitting of the authentication request and authentication response is effected in an encrypted fashion in each case, and the checking of the received authentication response includes decrypting the received authentication response.

Abstract: The invention proposes a method for processing data in a vehicle in which the data are received by a first processing unit via a network; in which the data are decoded by the first processing unit; and in which a piece of reproduction information comprising an output time or a piece of synchronization information is transmitted to the second processing unit. In addition, an appropriate apparatus is specified.

Abstract: An image processing system for a vehicle includes a first unit, a second unit and a video transmission link, which couples the first and second units, in terms of signaling, for transmitting digital video data. The video transmission link transmits digital video image signals having a predefined data format for a respective pixel of a video image, the data format including three blocks, each having a predefined number of bits. The first unit ascertains an uncompressed transformed video image signal suitable for transmission via the video transmission link as a function of a respective first video image signal such that the transformed video image signal has the predefined data format of the video transmission link.

Abstract: The invention provides a method for searching objects in a database by means of an index data structure which associates object attribute values to collections of spatial elements—such as tiles of a quadtree or cuboids of an octtree—defined to partition a space, herein a predefined number of spatial elements being combinable to a next-level spatial element.

Abstract: A motor vehicle (1) has a fixed rollover bar (8) that spans a passenger compartment of the motor vehicle. The motor vehicle (1) also has removable roof (16) that can be moved between a closed position where the roof (16) is arranged between a windshield frame (2) and the rollover bar (8) and a storage position where the roof (16) is behind the rollover bar (8). A linkage (15) is mounted to a vehicle body (19) behind the rollover bar (8) and can be articulated for moving the roof (16). Links (20, 21) of the linkage (15) lie in depressions (11, 23) on the rollover bar (8) when the roof (16) is in the closed position. Buffer elements (22) are between the links (20, 21) and the rollover bar (8).

Abstract: Disclosed is a vehicle pedal (1) for actuating a vehicle, wherein the pedal includes at least two metal sheets (10, 20), i.e. a bottom metal sheet (10) and a pedal metal sheet (20), which are spaced apart from one another by at least two springs (14). The bottom metal sheet (10) is provided with sides (12) that form an angle in the front and rear. Suspension points (13) for the springs (14) are arranged on the sides (12) while corresponding suspension points (22) are provided on the pedal metal sheet (20). Only the pedal metal sheet (20) is directly connected to the vehicle floor pan by a pan-mounted pivot bearing (23) so that linear momentum is not transmitted to the driver's foot (2) in case a mine explodes.

Abstract: An undercarriage for a construction machine having a support frame and at least one carrier roller positioned on an upper surface of the support frame for providing upper guidance to the chain or band. The carrier roller is constructed from two bearing pins coaxially arrange on opposite sides of the roller, and includes a plurality of axially parallel driving pins arrange equidistantly along a coaxial circumferential circle on one side face of the roller. The driving cams on the chain engage between two adjacent driving pins thereby eliminating relative movement between the chain or band and the carrier roller.
