    DETAILED DESCRIPTION

    [0058] FIGS. 1 and 2 show a screen system 10. The screen system 10 is arranged in an interior 12 of a vehicle. The interior 12 also includes a driver seat 14 and a passenger front seat 16. A driver sitting on the driver seat 14 is represented by one eye 18. A front seat passenger sitting on a passenger front seat 16 is represented by one eye 20.

    [0059] The screen system 10 includes a screen assembly 22 with a base component 24 and a screen component 26. The base component 24 is arranged in an interior of an instrument panel 28 of the vehicle.

    [0060] In the example of FIGS. 1 and 2, the screen component 26 protrudes over the instrument panel 28. The screen component 26 includes a screen unit 30 being configured for displaying information for a user of the vehicle, i.e. for the driver being represented by eye 18 and the front seat passenger being represented by eye 20. The screen component 26 is movable with respect to the base component 24 in several respects.

    [0061] First, the screen component 26 is translationally movable relative to the base component 24 along a translation direction T.

    [0062] In the example shown in FIGS. 1 and 2, the translation direction T is oriented substantially vertically within the interior 12 of the vehicle.

    [0063] Second, the screen component 26 is tiltable relative to the base component 24 around a tilting axis R1.

    [0064] In the example shown in FIGS. 1 and 2, the tilting axis R1 is oriented substantially horizontally within the interior 12 of the vehicle. At the same time, the tilting axis R1 substantially extends from left to right in the interior 12 of the vehicle with respect to a forward driving direction D. The corresponding tilting movement is illustrated by arrow 32.

    [0065] Third, the screen component 26 is rotatable relative to the base component 24 around a rotation axis R2.

    [0066] In the example shown in FIGS. 1 and 2, the rotation axis R2 is oriented substantially vertically within the interior 12 of the vehicle. The corresponding rotational movement is illustrated by arrow 34.

    [0067] Thus, the tilting axis R1 is perpendicular to the translation direction T and the rotation axis R2 is perpendicular to the tilting axis R1.

    [0068] The tilting of the screen component 26 around tilting axis R1 can also be seen in FIGS. 6 and 7. The rotational movement around the tilting axis R1, the rotational movement around the rotation axis R2 and the translational movement along the translation direction T may be performed independent from one another as will be explained in more detail below.

    [0069] The screen system 10 also includes a data processing apparatus 36. The data processing apparatus 36 is coupled to the screen assembly 22 such that a position of the screen component 26 of the screen assembly 22 is controllable by the data processing apparatus 36. To this end, the data processing apparatus 36 includes a first communication interface 38 which is configured to provide a positioning request to the screen assembly 22, more precisely to the screen component 26.

    [0070] The screen assembly 22 is communicatively connected to the data processing apparatus 36 via the first communication interface 38. Moreover, the data processing apparatus 36 includes a second communication interface 40 being configured to receive information characterizing a position of at least one eye 18 of the driver.

    [0071] In the example, a first eye tracking unit 42 is connected to the data processing apparatus 36 via the second communication interface 40. The first eye tracking unit 42 is configured to provide information characterizing the position of the eye 18.

    [0072] Furthermore, also a second eye tracking unit 44 is connected to the data processing apparatus 36 via the second communication interface 40. The second eye tracking unit 44 is configured to provide information characterizing the position of the eye 20, i.e. at least one eye of the front seat passenger. Thus, the second communication interface 40 is also configured to receive information characterizing a position of at least one eye 20 of the front seat passenger.

    [0073] The data processing apparatus 36 further includes a third communication interface 46 which is configured to receive information characterizing a position of at least one hand of the driver.

    [0074] In the example, a hands-on detector 48 is connected to the data processing apparatus 36 via the third communication interface 46. The hands-on detector 48 is arranged in a steering wheel 50 of the vehicle and is configured to provide information characterizing the position of at least one hand of the driver.

    [0075] Furthermore, the data processing apparatus 36 includes a fourth communication interface 52 configured to receive information describing a presence of the front seat passenger. In the example, a seat detector 54 is connected to the data processing apparatus 36 via the fourth communication interface 52. The seat detector 54 is configured to provide information describing the presence of the front seat passenger.

    [0076] Moreover, the data processing apparatus 36 includes a data storage unit 56 and a data processing unit 58. Using the data processing apparatus 36, more precisely the data storage unit 56 and the data processing unit 58, a method for controlling a position of the screen component 26 in the interior 12 of the vehicle can be performed. Thus, the data storage unit 56 and the data processing unit 58 are means 60 for carrying out the method for controlling a position of the screen component 26 in the interior 12 of the vehicle.

    [0077] The method is illustrated in FIG. 8. A first step S1 of the method includes receiving information describing a position of at least one eye 18 of the driver. This information is provided by the first eye tracking unit 42 as has already been explained above. Moreover, in the present example, the first step S1 includes receiving information describing a position of at least one eye 20 of the front seat passenger, if present. This information is provided by the second eye tracking unit 44 as has already been explained above. In the present example, in the first step S1 also information describing a position of at least one hand of the driver is received. As has already been explained, this information is provided by the hands-on detector 48. Furthermore, the first step S1 of the present example includes receiving information describing the presence of a front seat passenger. This information is provided by the seat detector 54 which has already been explained above.

    [0078] A second step S2 of the method includes determining the target position for the screen component 26. The target position is a function of the information received in the first step. In more detail, the target position is determined as a function of the position of the at least one eye 18 of the driver. The target position is also determined as a function of the position of the at least one eye 20 of the front seat passenger, if present. Furthermore, the target position is determined as a function of the position of the at least one hand. Also the target position is determined as a function of the presence of the front seat passenger. In the present example, it is assumed that no front seat passenger is present. Consequently, the target position has to be within a field of view of the driver only. In this context, the target position is determined such that a height difference H between the position of the driver's eye 18 and the screen component 26 lies between a pre-defined lower height difference threshold and a pre-defined upper height difference threshold.

    [0079] The height difference H is calculated between a center of the driver's eye 18 and a center of the screen unit 30 of the screen component 26 (cf. FIG. 2). The lower height difference threshold may be for example 10 cm, 15 cm or 20 cm. Generally, a low height difference means that the driver is able to comfortably see the screen component 26 and the information displayed thereon. However, the driver also needs to be able to see the environment, e.g. other road users, which are located behind the screen component 26 when regarded from the driver's position. The upper height difference may be 25 cm, 30 cm or 35 cm. the upper height difference is chosen such that the driver still can comfortably see the screen component 26 and the information displayed thereon. If the height difference is too large, the driver needs to bend his neck to a large extent in order to be able to see the displayed information. This is not comfortable for the driver.

    [0080] Moreover, the target position is characterized in that a vision angle α between a horizontal direction and a vision direction V connecting the driver's eye 18 and a center of the screen unit 30 lies between a lower vision angle threshold and an upper vision angle threshold. The lower vision angle threshold may be 2 degrees, 5 degrees or 8 degrees. The upper vision angle threshold may be 10 degrees, 15 degrees or 20 degrees.

    [0081] As has already been explained in connection with the height difference H, also the vision angle α needs to be chosen such that on the one hand, the driver can comfortably look beyond the screen component 26 and the screen unit 30. On the other hand, the driver needs to be able to comfortably see information being displayed on the screen unit 30. Such a target position guarantees good viewing conditions for the driver. This means that the driver can see information being displayed on the screen unit 30 easily and comfortably.

    [0082] Moreover, the target position is determined such that a reflection angle β between the screen unit 30 and a windshield 62 lies between a lower reflection angle threshold and an upper reflection angle threshold. This has the effect that both undesired reflections in the windshield 62 and undesired reflections on the screen unit 30 are avoided or reduced. Consequently, the driver is not distracted by such reflections.

    [0083] It is noted that the vision angle α and the reflection angle β have been explained in connection with FIG. 2 which shows a lateral view only. However, the vision angle α and the reflection angle β, of course, may also have angular components being visible in the top view of FIG. 1 only. These components are denoted α.sub.H and β.sub.H. In the example of FIG. 1, β.sub.H is 0 degrees. The above explanations concerning the vision angle and the reflection angle of course also apply to the components α.sub.H and β.sub.H.

    [0084] In a third step S3 of the method, the screen component is requested to move to the target position. This is done by sending a corresponding control signal from the first communication interface 38 to the screen assembly 22. In this context, the target positon may relate to a position of the screen component 26 in which a front surface of the screen unit 30 is perpendicular to the viewing direction V of the driver. It is noted that in a case in which the presence of a front seat passenger is detected, the target position, of course, needs to be determined such that also the front seat passenger is able to see information being displayed on the screen unit 30.

    [0085] The screen assembly 22 will now be explained in more detail in connection with FIGS. 3 to 7.

    [0086] The base component 24 is composed of a first, plate shaped part 24a and a second, U-shaped part 24b.

    [0087] The screen component 26 is supported on the base component 24, more precisely on the second part 24b thereof, via a translational guiding means 64.

    [0088] The translational guiding means 64 is kinematically arranged between the screen component 26 and the base component 24 and, thus, makes it possible to move the screen component 26 with respect to the base component 24 along the translation direction T. The translational guiding means 64 includes two slots 66a, 66b which hare arranged at an interior side of the legs of the U-shape of the second part 24b respectively. Moreover, the translational guiding means 64 includes two guiding arms 68a, 68b which are guided in the slots 66a, 66b respectively. An end of each of the guiding arms 68a, 68b is supported on the screen component 26.

    [0089] Thus, the screen component 26 can be moved relative to the base component 24 by sliding the guiding arms 68a, 68b in the respective slots 66a, 66b.

    [0090] The screen assembly 22 also includes a translational drive unit 70 being coupled to the screen component 26 and being configured for automatically moving the screen component 26 with respect to the base component 24 along the translation direction T. The translational drive unit 70 includes two toothings 72a, 72b which are arranged on lateral sides of the guiding arms 68a, 68b respectively. The guiding arms 68a, 68b thus form racks.

    [0091] Moreover, the translational drive unit 70 includes two motor units 74a 74b. Each of the motor units 74a, 74b includes an electric motor and a pinion 76a, 76b being mounted to an output shaft of the motors respectively.

    [0092] The arms 68a, 68b forming racks and the pinions 76a, 76b form a rack and pinion mechanism.

    [0093] Thus, the screen component 26 may be automatically moved along the translation direction T by operating the motor units 74a, 74b.

    [0094] The screen assembly 22 also includes a first rotational guiding means 78 being kinematically arranged between the screen component 26 and the base component 24 such that the screen component 26 is tiltable relative to the base component 24 around the tilting axis R1.

    [0095] The screen component 26 is mounted on each of the guiding arms 68a, 68b via a motor unit 80a, 80b respectively.

    [0096] Each of the motor units 80a, 80b includes a motor shaft 82a, 82b and the screen component 26 is connected to the motor shafts 82a, 82b.

    [0097] Thus, the screen component 26 can be tilted relative to the base component 24 by turning the motor shafts 82a, 82b with respect to the remaining parts of the motor units 80a, 80b.

    [0098] The screen component 26 can be automatically tilted by actuating the motor units 80a, 80b. Thus, the motor units 80a, 80b also form a first rotational drive unit 84.

    [0099] Furthermore, the screen assembly 22 includes a second rotational guiding means 86 being kinematically arranged between the screen component 26 and the base component 24. More precisely, the second rotational guiding means 86 is arranged between the first part 24a of the base component 24 and the second part 24b of the base component 24.

    [0100] Using the second rotational guiding means 86, the screen component 26 is rotatable relative to the first part 24a of the base component 24 around the rotation axis R2.

    [0101] The first part 24a and the second part 24b are connected via a motor unit 88. The motor unit 88 includes a motor body 90 and a motor shaft 92.

    [0102] In the present example, the motor body 90 is arranged in the first part 24a and the motor shaft 92 is connected to the second part 24b.

    [0103] Thus, the screen component 26 can be rotated around rotation axis R2 by turning the motor shaft 92 relative to the motor body 90. This can be done automatically by actuating the motor unit 88. Thus, the motor unit 88 also forms a second rotational drive unit 94 for automatically rotating the screen component 26 with respect to the base component 24 around the rotation axis R2.

    [0104] It is noted that the translational drive unit 70, the first rotational drive unit 84, and the second rotational drive unit 94 may be operated independent form one another. Consequently, the rotational movement around the tilting axis R1, the rotational movement around the rotation axis R2 and the translational movement along the translation direction T may be performed independent from one another.

    [0105] As can be seen from a comparison of FIGS. 3 and 4, the translational guiding means 64 and the translational drive unit 70 may also be used to make the screen component 26 extend fully or partially over the instrument panel 28. Thus, the portion of the screen unit 30 which can be seen may be adapted to an amount and a type of information to be displayed to the driver or the front seat passenger.
