wherein the processor is further configured to:

determine a viewing direction of the occupant using the image data;

determine a reading speed of the occupant using the viewing direction of the occupant; and

determine the time-dependent change of the position of the display information using the reading speed of the occupant.

9 . The control device of claim 1 ,

wherein the control instructions indicate that the display information is to be displayed in a portion of the display unit;

wherein the time-dependent change of the position of the display information is a time-dependent change of the position of the portion.

10 . A vehicle comprising the display unit and the control device of claim 1 .

11 . A method for controlling a display unit arranged in a vehicle, the method comprising:

receiving first data representing a surrounding of a vehicle;

determining a driving trajectory of the vehicle using the first data;

receiving second sensor data representing a head movement of an occupant of the vehicle;

using a speed of the vehicle, determining a time-dependent relative movement between the head movement of the occupant and a vehicle movement according to the driving trajectory;

determining a time-dependent change in a position of display information, which are to be displayed on a display unit arranged in the vehicle, such that the change in the position of the display information fully or partially compensates for the relative movement; and

generating control instructions for controlling the display unit to display the display information according to the time-dependent change of the position.

12 . The method of claim 11 , further comprising;

determining, using the first data, a predicted vertical movement of the vehicle, wherein the time-dependent relative movement comprises a time-dependent vertical relative movement between the head movement of the occupant and the predicted vertical movement of the vehicle; and/or

determining, using the first data, a predicted lateral movement of the vehicle, wherein the time-dependent relative movement comprises a time-dependent lateral relative movement between the head movement of the occupant and the predicted lateral movement of the vehicle.

13 . The method of claim 11 ,

wherein the display unit is mounted in the vehicle; or

wherein the display unit is a display unit of a user device worn by an occupant.

14 . The method of claim 11 ,

wherein the display information comprise a text; and

further comprising determining the time-dependent change of the position of the text such that that text to be display on the display unit follows the driving trajectory.

15 . The method of claim 14 ,

further comprising determining the time-dependent change of the position of the text such that text to be display on the display unit is to be read from bottom to top.

16 . The method of claim 14 ,

wherein the first data comprise image data showing an image in driving direction of the vehicle;

and further comprising generating the control instructions to display at least a section of the image on the display unit as a background of the text.
