  • Publication number: 20190359153
    Abstract: A method for controlling two serially disposed relays that switch a load with two different safety levels depending on the driving situation in a vehicle includes querying state information that includes movement state information and/or coasting operation information of the vehicle, determining a safety level of the two different safety levels depending on the driving situation, using the state information, detecting a relay of the two serially disposed relays using a balancing rule when the safety level determined in step b) represents a lower safety level of the two safety levels, switching the selected relay into a non-conductive state and keeping the further relay in a conductive state when a first request signal for switching off the load is received, and switching the selected relay into a conductive state when a second request signal for switching on the load is received.

  • Patent number: 10436830
    Abstract: The present disclosure relates to a device for recognizing disruptions in an on-board power supply. The device comprises a reception unit adapted to receive a first and a second temporal sequence of measurement values, the measurement values of the first sequence being measured at a first measuring point of the on-board power supply and the measurement values of the second sequence being measured at a second measuring point of the on-board power supply differing from the first measuring point, and the measurement values representing current or voltage values, and an evaluation unit adapted to recognize the occurrence of a disruption based on a comparison of the first dispersion of the measurement values of the first sequence and a second dispersion of the measurement values of the second sequence.

  • Patent number: 10378608
    Abstract: A temperature-independent rotation damper 100 is presented. A housing 108 and a piston 102, between which a viscous liquid is located in annular gaps 118, 120, rotate one around the other. When the temperature falls, the damping by the viscous liquid increases. This effect is countered by reducing the effective area which constitutes the braking action, or by enlarging the volume in the annular gaps 118, 120. As the drive, a material having a positive expansion coefficient is used, which material drives a piston 132. In this way, the damping of the rotation damper 100 is broadly practically independent of the temperature.

  • Patent number: 10345351
    Abstract: The present disclosure relates to a method for monitoring an on-board electrical system of a vehicle having at least one distributor and a load that are connected together via a cable. In one implementation, the method includes reading in a sequence of data for a number of parameters representing information about operation of the vehicle by a driver and/or about a state of the vehicle and/or a state of the driver and/or a driving environment; classifying the data as a normal value or an error value; and evaluating the data classified as an error value or a normal value. The normal values may lie within a state space separated from the error values by a discrimination limit. Evaluating the data classified as an error value may include determining if the data classified as an error value fulfils a criterion, and evaluating the data classified as a normal value may include statistically evaluating to determine a stochastic parameter and determining if the stochastic parameter exceeds a threshold value.

  • Patent number: 10337544
    Abstract: The present disclosure relates to a screw connection comprising a support component, an additional component and a screw to fasten the support component to the additional component. The support component has a tube made of thermoplastic foam to accommodate the screw in a friction and positive fit. The screw has a blunt-edged thread, enabling the screw to compress the foam in the tube as it is driven in. The ratio of the inner diameter of the tube to the diameter of the screw depends on the degree of foaming of the tube and decreases as the degree of foaming increases. In comparison to conventional screws, the threads of the screw of the present disclosure penetrate less deeply into the foam or they displace it, preventing damage to the tube while enabling a tight fit.

  • Patent number: 10279737
    Abstract: An illuminating device for a vehicle includes a carrier module, a flat light guide attached to the carrier module with a plurality of emitting points, and multiple light sources for illuminating the light guide. The flat light guide is concealed with a translucent haptic layer, which is attached to a visible side of the light guide, which, in turn, is covered by a decorative layer. The illuminating device comprises a rope-like light guide, which has an inherent light source and is connected to the decorative layer via a retaining device. This therefore results in a flat arrangement, which can be easily integrated into the interior parts and simultaneously enables illumination over a large surface area. In doing so, additional light effects can be integrated by means of the rope-like light guide. The illuminating device is not visible while switched off, as the illuminating device is covered by the decorative layer.
