Abstract

A method for operating a headlight device of a motor vehicle, wherein the headlight device comprises a projection device and a control unit which is designed to control the projection device for projecting a predetermined light pattern in a predetermined projection region of the projection device. The light pattern in a polygon operating mode of the headlight device comprises a polygon mesh with polygon surfaces having polygon edges defined by projection points as corner points. At least partially different projection brightnesses are assigned to the polygon surfaces, wherein at least one physical property is assigned to at least one polygon feature of the polygon surfaces, in particular at least to the corner points, wherein, for dynamic adjustment of the light pattern in a dynamic submode of the polygon operating mode: time-current operating data of the motor vehicle and/or measurement data of the motor vehicle are recorded, which describe the driving state of the motor vehicle and/or environmental features relevant to the physical property in an environment of the motor vehicle encompassing the projection region, an environment model is provided based on the operating data and/o…
