Method for operating a headlight for a motor vehicle
First Claim
1. A method for operating a headlight for a motor vehicle, said headlight comprising a plurality of light emitting diodes, the method, comprising:
- receiving a request signal for a high-beam mode;
determining a road class of a roadway on which the motor vehicle is located;
activating a first group of the plurality of light emitting diodes for providing a first high-beam distribution with the headlight in the event that the road class is different from a highway; and
determining a structural separation between lanes of a highway and activating a second group of the plurality of light emitting diodes for providing a second high-beam distribution with the headlight by activating the second group of the plurality of light emitting diodes in response to determining the structural separation in the event that the highway is determined as the road class.

Abstract
The invention relates to a method for operating a headlight (12) of a motor vehicle (10), which headlight (12) comprises a plurality of light emitting diodes, by receiving a request signal for a high-beam mode; determining a road class of a roadway on which the motor vehicle (10) is located; activating a first group of the plurality of light emitting diodes for providing a first high-beam distribution (20) with the headlight (12) in the event that a road class different from a highway (18) is determined; and activating a second group of the plurality of light emitting diodes for providing a second high-beam distribution (26) with the headlight (12) in the event that a highway (18) is determined as the road class.

12. An automobile, comprising:
-
a headlight including a plurality of light emitting diodes; a detection device which in operation determines a road class of a roadway and outputs determination information; and a control device which in operation receives a signal corresponding to a request for a high-beam mode of the headlight, in response to the signal corresponding to the request for a high-beam mode of the headlight and the determination information corresponding to a non-highway road class, the control device in operation activates first subsets of the plurality of light emitting diodes in a non-highway configuration, the first subsets include a first middle region of the plurality of light emitting diodes at a first illuminance, a first edge region of the plurality of light emitting diodes at a second illuminance that is less than the first illuminance, and a second edge region of the plurality of light emitting diodes at a third illuminance that is less than the first illuminance; in response to the signal corresponding to the request for a high-beam mode of the headlight and the determination information corresponding to a highway road class, the control device in operation activates second subsets of the plurality of light emitting diodes in a highway configuration, the second subsets include a second middle region of the plurality of light emitting diodes at a fourth illuminance, a third edge region of the plurality of light emitting diodes at a fifth illuminance that is less than the fourth illuminance, a fourth edge region of the plurality of light emitting diodes at a sixth illuminance that is less than the fourth illuminance, a first intermediate region of the plurality of light emitting diodes between the fourth and fifth illuminances, and a second intermediate region of the plurality of light emitting diodes between the fourth and sixth illuminances. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
