  • Publication number: 20240140305
    Abstract: A method for operating at least one direction indicator of a motor vehicle, wherein, as of an actuation time, the direction indicator outputs a light signal comprising a periodic repetition of alternately successive on-phases and off-phases. A discrepancy of a starting phase angle of the light signal with respect to a predefined reference signal is determined at the actuation time and is compared with a predefined target phase angle assigned to the direction indicator. When there is a phase offset between the starting phase angle and the target phase angle—at least two of the on-phases and/or the off-phases of the light signal are extended or shortened by a different time difference value in each case after the actuation time such that the phase angle of the light signal with respect to the reference signal then corresponds to the predefined target phase angle, and/or—the light signal is started with a first off-phase (11) at the actuation time.

  • Publication number: 20240131980
    Abstract: The present disclosure relates to a motor vehicle comprising at least one illumination device, by means of which at least one light signal can be generated which is visible from outside the motor vehicle, and comprising at least one acoustic device, by means of which at least one acoustic signal can be generated which is audible from outside the motor vehicle. The at least one control device of the motor vehicle is configured to check whether at least one output condition is satisfied and, if the at least one output condition is satisfied, to control the at least one illumination device and the at least one acoustic device in such a way that the light signal and the acoustic signal are generated simultaneously.

  • Publication number: 20230278485
    Abstract: A method for operating an illuminating device of a motor vehicle, wherein light is radiated into a lighting volume by the illuminating device, wherein a control condition is evaluated, the fulfillment of which depends on whether the lighting volume comprises a partial lighting volume by which an area and/or an environment volume is illuminated that is illuminated or can be illuminated by an infrastructure luminaire, wherein when the control condition is fulfilled, the illuminating device is controlled in such a way that light is radiated into the partial lighting volume with a different light intensity than into a residual lighting volume of the lighting volume, which residual lighting volume lies outside the partial lighting volume.

  • Patent number: 10800326
    Abstract: A motor vehicle, comprising at least one linear lighting device for directly or indirectly lighting a vehicle interior. The at least one lighting device extends, at least in some sections, horizontally along at least one component of the motor vehicle. The motor vehicle additionally comprises a position-sensing unit for sensing ego information describing a position and an orientation of the motor vehicle. The at least one lighting device is divided horizontally into a plurality of lighting segments, each having a fixed emission profile. The motor vehicle has a control device, configured to: determine a direction of the destination in relation to the motor vehicle; select a sub-group of the plurality of lighting segments comprising at least one lighting segment to be activated; and activate the at least one lighting segment belonging to the sub-group according to lighting brightness or lighting color of the at least one lighting segment.

  • Patent number: 10645529
    Abstract: A motor vehicle is disclosed that includes at least one linear lighting means for directly and/or indirectly lighting a vehicle interior. A position-sensing unit senses ego information describing a position and an orientation of the motor vehicle. A control device determines, from location information describing the position of a person, and from the ego information, direction information describing a direction of the person in relation to the motor vehicle (1), selects, in accordance with the direction information, a sub-group of lighting segments that includes at least one lighting segment to be activated, and activates the lighting segment belonging to the sub-group in accordance with a configuration, which specifies the lighting brightness and/or the lighting color of the lighting segment, and which visualizes the position of the person.
