Motor vehicle lighting system

A motor vehicle lighting system (1) comprising:

• at least two adaptive motor vehicle headlights (2), wherein an adaptive motor vehicle headlight (2) is a headlight that is designed to produce dipped beam distribution (AL) and adaptive full beam distribution (FL) having a resolution of at least two individually controllable segments (FLs1, FLs2, Fls13), wherein the dipped beam distribution (AL) has a region assigned for road sign lighting, hereinafter referred to as sign light region (ALsl), which at least partially overlaps with an emission region, which is associated with the full beam distribution (FL);
• at least one camera system (3) for detecting the environment of the motor vehicle lighting system (1) and for outputting environmental data (D) corresponding thereto, by the camera system (3) being designed to detect and determine the relative position (Pos1, Pos2, Pos3) of road users (4′, 4′, 4″) measured with respect to the at least two adaptive motor vehicle headlights (2);
• and
• at least one control unit (5), which is connected to the camera system (3) for receiving the environmental data (D) and to the at least two adaptive motor vehicle headlights (2) for controlling the adaptive motor vehicle headlights (2), wherein the control unit (5) is designed to use the environmental data (D) by comparing a detected relative position (Pos) of a road user (4) with a first position range (2′), which can be illuminated by the segments (FLs1, FLs2, Fls13) of the adaptive full beam distribution (FL), to infer the presence of a glare hazard and to define any detected road users (4′, 4″) in said illuminable position range (2′) as road users (4′, 4″) to be masked, and if there are road users (4) to be masked, to deactivate in any case those controllable segments (FLs1, FLs2, Fls13) of the full beam distribution (FL) that would otherwise shine directly onto the road users (4) to be masked,
• wherein the control unit (5) is further designed, if there is a road user (4′, 4″) to be masked, to carry out a comparison of its detected relative position (Pos) with a second position range (2″), which can be illuminated by the sign light region (ALsl), and thus to infer the presence of road users (4) to be masked within the second position range (2″), wherein each adaptive motor vehicle headlight (2) is further provided with a control means (2a), wherein each control means (2a) is designed to control the intensity of the illumination of the sign light region (ALsl) by the respective adaptive motor vehicle headlight (2) differently from the intensities of the remaining regions of the dipped beam distribution (AL), wherein for this purpose the control unit (5) is connected to the control means (2a) and the control means (2a) is controlled in such a way that in the case of the presence of a road user (4″) to be masked being detected within the second position range (2″), the intensity of light (I2) emitted into the sign light region (ALsl) is also reduced compared to a state where no road user (4) to be masked is detected (I1) within the second position range (2″), and
• wherein the reduction in the intensity (I2) of the light emitted into the sign light region (ALsl) compared to a state where no road user (4) to be masked is detected (I1) within the sign light region (ALsl) is at least 30%.
