Description

Mirror tracking arrangement for a vehicle, method and vehicle with the mirror tracking arrangement The invention relates to a mirror tracking arrangement for a vehicle with the features of claim 1. The invention also relates to a method for mirror tracking and a vehicle with the mirror tracking arrangement. Comfort functions in vehicles are designed to adapt to the individual driver when they get into the vehicle. Memory functions allow the seat position and other adjustment options to be saved and recalled. For example, the publication DE 10003220 A1 discloses a method and a device for driver- and/or passenger-specific adjustment of the seat and seat-related units in motor vehicles, whereby structure-related data is determined by measuring at least one time the at least essential points of the overall stature of a driver or a vehicle passenger. By reading in this data and by including the dimension data in the motor vehicle, seat and/or seat contour settings and, if necessary, also the mirror and/or steering wheel settings are ergonomically optimized and automatically adjusted. It is an object of the present invention to propose a mirror tracking arrangement for a vehicle which provides an improved field of vision for a driver of a vehicle. This object is achieved by a mirror tracking arrangement, a method and a vehicle with the mirror tracking arrangement. Preferred or advantageous embodiments of the invention emerge from the subclaims, the following description and the attached figures. The subject of the invention is a mirror tracking arrangement which is suitable and/or designed for a vehicle. The vehicle is in particular a road vehicle. It can be, for example, a passenger car, truck, bus or the like. In principle, the vehicle can also be designed as a three-wheeler or a two-wheeler. The mirror tracking arrangement has a mirror device, wherein the mirror device comprises a mirror and an adjustment device. The mirror is designed in particular as an optical mirror, e.g. with a metal coating as a mirror surface. For example, the mirror can be realized as a plane mirror. However, it is also possible for the mirror to be designed as a curved mirror. It is also possible for the mirror to have several mirror segments that cover different fields of view. The adjustment device is designed to adjust the mirror, for example via two independent axes, so that the mirror can be tilted. Other actuators are also conceivable which allow the mirror to be adjusted. By adjusting the mirror, the orientation of the field of view of the mirror for a driver can be adjusted. When the mirror is adjusted, the field of view in the mirror changes, which can be seen by the driver or from an observation position that corresponds to the driver. Since the mirror is tilted, the orientation of the field of view changes when it is adjusted. The field of view orientation therefore depends on the driver's position on the one hand and on the position and setting of the mirror on the other. However, by adjusting the mirror, the field of view orientation of the mirror can be adjusted or set, assuming the driver's observation position remains constant. The field of view orientation is to be understood in particular as the direction of the field of view. For example, the direction of the field of view is the direction starting from a mirror reference point, e.g. the mirror center, where the direction is determined by an optical path from the observation position of the Driver is defined by the mirror reference point. Alternatively, the field of view alignment can also be viewed as an alignment of the mirror surface. In particular, the field of view alignment ensures that a predeterminable field of view is displayed on the mirror for the driver. The mirror tracking arrangement has a camera device, wherein the camera device comprises a camera and an evaluation device. The camera is designed in particular as an interior camera. The camera is understood in particular to be a spatially resolving sensor device. The camera can be designed as a grayscale camera, as an RGB camera, IR camera, RGB-IR camera or ToF camera (time-of-flight). For example, the camera is arranged and/or can be arranged on the interior mirror of the vehicle. Optionally, the camera is designed to be motor-driven. In particular, the camera is used alternatively or additionally for driver and passenger monitoring. The camera is arranged and/or can be arranged to detect a driver on a vehicle seat of the vehicle. The driver uses the mirror of the mirror device in particular for orientation in traffic. The evaluation device is designed to determine the driver's eye position data. The eye position data can be, for example, the position of the driver's two eyes. Alternatively, a standardized eye position of the two eyes can also be used as eye position data. The driver and/or his eyes are thus approximated to a one-eyed cyclops. The eye position data can be recorded in a coordinate sy
