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 () at the actuation time. The duration of the first off-phase corresponds to a time offset corresponding to the phase offset between the starting phase angle and the predefined target phase angle, with the result that an on-phase of the light signal following the first off-phase is at the target phase angle with respect to the reference signal.

Method for operating at least one direction indicator of a motor vehicle, and motor vehicle

A method for operating a motor vehicle, wherein the motor vehicle has a lighting device comprising at least two headlight devices, wherein the headlight devices is arranged horizontally offset on a front side of the motor vehicle and each having one or more dimmable lamps, wherein a spatial region extending in front of the motor vehicle over a horizontal angular range can be illuminated by each headlight device according to a respective brightness generated by the lamp or lamps, wherein, before or during a reverse travel of the motor vehicle, as a function of a steering angle of the motor vehicle, the brightnesses of the lamp or lamps of at least one of the headlight devices are adjusted,—wherein, when using headlight devices comprising multiple lamps, the lamps are adjusted such that at least one portion of the spatial region-opposite the direction of the turning of the steering wheel is illuminated at an increased brightness, and/or—wherein, when using headlight devices comprising at least one lamp, the brightness of the at least one lamp of a headlight device in the direction of the steering angle is dimmed.

Method for operating a motor vehicle, and motor vehicle

A method for illuminating vehicle surroundings of a motor vehicle that comprises an illumination device and a detection device, wherein the illumination device is set up to illuminate at least part of a solid angle region of the vehicle surroundings with different illumination patterns, in particular with visible light, wherein the illumination patterns each predefine illumination intensities for different solid angle subregions of the solid angle region, comprising the steps of: illuminating the vehicle surroundings with a first of the illumination patterns by means of the illumination device, detecting a light pattern that results from the illumination of the vehicle surroundings with the first illumination pattern by means of the detection device, selecting a second of the illumination patterns on the basis of the detected light pattern, and illuminating the vehicle surroundings with the second illumination pattern by means of the illumination device.

Method for illuminating vehicle surroundings, and motor vehicle

The present disclosure relate to a motor vehicle comprising a sensor device for detecting the position and the distance from an object located in front of the motor vehicle and a device for projecting a light marker onto the ground in the region of the object, wherein the device is configured, on the basis of the detected position and distance data, to project either a round or polygonal light marker on a region around the object, wherein this is dimensioned is such a way that its border is indicates a minimum distance to be maintained around the object when driving past, and/or the device is configured to generate a linear light marker and project it on the ground into the region in front of the motor vehicle running by the object in such a way that the distance of the light marker corresponds to the minimum distance to be maintained from the object when driving past and indicates when the motor vehicle can reenter the lane after passing the object while maintaining a safe distance.
