The optical devices have to be adjusted so that the operator of the optical Receive facilities supplied information without major movements of the head can. In the cheapest In this case, small eye movements should suffice. at best It should be necessary to head something in the direction of the concerned to turn optical device.
  • Known optical devices must be individually be brought into the optimum position. This can be done by a purely manual mechanical adjustment done, as for example is common in adjusting the interior mirror of a car. Furthermore The use of adjusting devices is known, which is a simplification cause the adjustment of optical devices of a vehicle. For example, they are common the outside mirrors of a vehicle through the use of an electromotive actuator formed adjustable by means of one or more switches. This is In particular, it no longer required to adjust the exterior mirrors to open the window. In addition, it is avoided that the operator to adjust the exterior mirror move the head out of the normal viewing position (through a spatial Moving the head), and then after each adjustment of the optical Setup and moving back of the head to the normal viewing position the attained setting too check.
  • One significant disadvantage in all these known methods and devices to set several optical devices of a vehicle in that even with the use of adjusters the Setting all the optical devices requires a long time.
  • From the DE 195 19 619 A1 is a reflection angle-automatic adjustment for exterior and interior mirrors is known in which a driver's seat / backrest sensor is used to determine the driver's head position in order to determine the most favorable for vehicle mirror reflection angle individually and set via a controller:
  • Out JP 60-158303 A - Abstract, Pat. Abstr. Japan Sect. P Vol. 9 No. 334 (P417) p. 103 (27.12.1985) is a device for detecting the position of the eyes of a Driver and dependent on it Alignments of mirrors known.

  • hereby will the for the setting of all The time required for the optical devices drastically reduced and the operator, especially the driver of a motor vehicle, practical Completely from these adjustment activities relieved.
  • The optical devices to be set may be the interior mirrors and exterior mirrors of the vehicle, as well as display devices, for example a combination instrument or the display of a radio. In addition to adjusting the angular position of an information-providing surface of an optical device, such as a pivotable about two axes or wobble mirror element, an optical element in its angular position can be adjusted, which affects the visibility of the information of at least one optical device. Such an optical element may be, for example, the cover glass of a Combi instruments act, which ensures, among other things, by its anti-reflection optimal recognizability of the actual information bearing surface of the instrument cluster. Since the anti-reflective properties of such a cover glass are also dependent on the viewing direction on this coverslip - the direction of the distance between the eye posi tion of the operator and a certain points of the object under consideration, here the cover glass understood, can - by adjusting a each optimal angle of the cover glass with respect to the viewing direction an optimal anti-reflection effect can be achieved.
  • The Angle adjustment of both the information providing surface as also the optical information influencing the recognizability of the information Elements can both by pivoting the entire optical Device as well as by the sole pivoting of the respective element or related components.
  • Next An angular adjustment of the optical device may also their optical properties dependent be set from the determined eye position. For example For example, the brightness and / or contrast of a liquid crystal display (meant is here at a fixed viewing angle, for example when viewing the display vertically, resulting contrast) depending on the viewing angle be set to an optimal value on the display, for example, by a change the control voltage affecting these parameters.
  • These the optical device to be adjusted is a display device, so the entire display device or the actual Information-providing element of the display device with regard to his angle are adjusted so that when viewing a certain point of the surface the normal vector on the surface at this point a predetermined position in relation to the viewing direction.
  • A Apparatus for carrying out of the above Method comprises a detection device for determining the Eye position of an operator and an evaluation and control unit, which the signal is supplied to the detection device. The detection device transmitted the eye position of the operator to the evaluation and control unit, so that the evaluation and Control unit by the control of an adjustment for the relevant optical device can set them in the required manner.
  • The Detection device according to an embodiment of the invention, the Make eye position by the image evaluation of a camera signal.

The necessary procedures and procedures for image analysis and to determine the eye position are on known and require here none nearer Explanation.
  • The Can take the picture from two different directions using two cameras or using a single camera, which is reciprocable between two positions. Instead of A movement of the camera can also be a double, if necessary switchable optics can be used.
  • To a further embodiment According to the invention, the detection device has a scanning device on which one over a detection range movable light beam, preferably a Laser beam, emitted. Furthermore, the detection device comprises a light sensor, which for detecting the reflected or scattered light serves. By evaluating the received light signal then can the one spatial Angle or angular range of the transmitted light beam can be determined below which the light beam is reflected on one eye (or glasses) becomes. This recognition can be achieved by evaluating the intensity or the intensity distribution of the reflected beam or other optical properties of the reflected or scattered light done. In knowledge of the spatial Angle or the position of this ray of light under which the eye position was detected, and by evaluating the transit time of the light between Sending and receiving can then be the spatial position of the eye be determined.
  • to Improve the accuracy or increase the security of the investigation In an eye position, the detection device can also detect both eyes to capture. In this case, for further simplified editing a single spatial one Point be used as an eye position, for example, the Center of the distance between the two eye centers. If only the detection of a single eye is provided, then its Center point continues to be used as the point of eye position.
  • According to a further embodiment of the invention, values for the desired observation direction of a mirror and / or values for the desired position of a display device and / or values for optical properties of a display device can be stored in the evaluation and control unit. These setpoints can then be from the evaluation and control unit retrieved when needed and the optical devices are adjusted taking into account the determined eye position so that the desired setpoints are achieved. Such setpoints can either be fixed or be determined by the operator in a calibration process.
  • Of course it is it also possible in this case for different operators different values or sets of Save values.
  • One appropriate calibration can be done by the evaluation and control unit automatic triggered be, for example, after a power failure or disconnection the battery of the vehicle or in such cases, in which the evaluation and control unit according to predetermined criteria determines that the stored values are not in a meaningful Area lie.
  • Of course you can the calibration process is also triggered by the operator, for example the case that the operator determines that the stored Values do not meet their wishes correspond.
  • The Enter the desired Setpoints can be done in a simple manner by a teach-in procedure. It allows the evaluation and control unit to manually adjust the one or several optical devices, for example by means of a connected to the evaluation and control unit control element (switch, Joystick or the like). After reaching the desired target position this is detected by the evaluation and control unit. This can be done in the relevant adjustment of the optical device be provided suitable sensor whose signal the evaluation and Control unit supplied is.
  • Of the the reference value in question is from the evaluation and control unit, for example upon receipt of an operator-initiated acknowledgment signal, in the relevant Memory taken over.
  • The automatic Adjusting the optical device and / or the required for this Detecting the eye position of the operator can either be based on requirements by the operator and / or in predetermined temporal preferably constant intervals carried out become.
  • Further embodiments The invention will become apparent from the dependent claims.
  • The Invention will now be described with reference to a drawing embodiment explained in more detail. The single figure shows the schematic representation of an embodiment of the invention with three to be adjusted with respect to their optical axis optical devices.
  • The device provided in a motor vehicle not shown in detail in the figure 1 according to the invention comprises two exterior mirrors 3 , one in the vertical center plane of the schematically indicated windshield 5 arranged rearview mirror 7 and a swiveling instrument cluster 9 which has a plurality of individual display devices, such as tachometer, tachometer, fuel gauge, oil pressure gauge, etc. In addition, there is a radio 10 with a liquid crystal display 12 provided in the dashboard.
  • In the instrument cluster 9 is a detection device 11 provided, for example, emits a light beam, preferably a laser beam, with which a predetermined solid angle is scanned. For this purpose, the light beam is moved in a predetermined manner, for example meander-shaped or spiral, over the spatial angle to be scanned. In addition, the detection device comprises 11 an optical receiver which detects reflected or scattered light. Since, in contrast to virtually all other surfaces, the human eye or the cornea (and / or the lens) exhibits a characteristic reflection behavior, the detection device can 11 First, determine under which beam angle the detected eye is located. The distance from the position of the detection device can be determined over the duration of the light signal. Thus, the position of the detected eye is clearly determinable. For further calculations, the detection device 11 determine the center of the eye. In addition, it is possible to detect not only one eye but both eyes, for example, to eliminate the possibility of errors by other similar reflective objects. In this case, for example, the center point of the distance between the eye centers can be used for the further calculation as a punctiform eye position.
  • The of the detection device 11 Eye position determined in this way is provided by an evaluation and control unit 13 used for the required adjustment of the optical devices.
  • To enable the automatic adjustment of the optical devices, is the evaluation and control unit 13 with adjustment devices 15 for the exterior mirrors 3 with an adjustment device 19 for the interior mirror 7 with an adjustment device 17 for in the illustrated embodiment by a Axis swiveling combination instrument 9 and with an adjustment of the radio 12 connected.
  • As already explained above, are in the evaluation and control unit 13 Setpoints for the desired settings of said optical devices stored. In addition, in the evaluation and control unit 13 the positions of the optical devices to be set or the positions of the elements to be set (for example, based on the position of the detection device) stored. The knowledge of the positions of the optical devices or their relevant elements and the position of the detection device (even if this forms the origin of a corresponding coordinate system) is required for the calculation of the viewing direction from the eye position to the optical devices or their elements.
  • The setting of the mirror is done in such a way that the evaluation and control unit 13 first depending on the eye position P, which by the detection device 11 was determined, the viewing directions B 3 on the exterior mirrors 3 (Preferably on the centers), the viewing directions B 7 on the rearview mirror 7 (preferably on its center) and the viewing direction to a specific point of the display surface of the instrument cluster 9 calculated. From these directions and from the (optionally operator-dependent) stored values for the observation directions R 3 for the exterior mirrors 3 and R 7 for the rearview mirror 7 the evaluation and control unit can then the necessary to comply with the observation directions R 3 and R 7 positions of the mirror 3 . 7 to calculate. This is done in a simple manner by applying the law of refraction, wherein the mirror 3 . 7 must be set so that in the intersections of the mirror surfaces with the line of sight B 3 , B 7, the respective normals A 3 , A 7 each form the bisector between the line of sight B 3 , B 7 and the desired observation directions R 3 , R 7 .
  • The adjustment of the instrument cluster, which can be swiveled about a substantially horizontal axis 9 is done in such a way that the respective line of sight at a certain point of the instrument cluster with the normal at this point includes a certain angle.
  • Since the visibility of a liquid crystal display depends very much on the viewing direction of the display, in the embodiment according to the single figure is also an adjustment of the contrast of the liquid crystal display 12 of the radio 10 intended. For this purpose, the evaluation and control unit again determines the viewing direction to a specific point of the liquid crystal display 12 and then accesses a stored dependency of the contrast to be set on the determined angle. From this determines the evaluation and control unit 13 the contrast value to be set and controls a non-illustrated adjusting device for the contrast so that this value is reached.
  • The evaluation and control unit 13 In the original state, it is possible to store fixed values for the desired target settings of the optical devices, in particular the viewing directions for the mirrors, the position of the combination instrument and the contrast of the liquid crystal display of the radio.
  • In addition, it may be possible for these values to be supplemented by a set of further values that can be specified by the operator. Of course, several sets of values can also be stored for several operators. These can then by the operator concerned by means of an input device 21 for the evaluation and control unit 13 be retrieved.
  • The input device 21 can also serve the evaluation and control unit 13 into a calibration mode. In this calibration mode, the automatic adjustment of the optical devices is switched off. The operator can then use the input device 21 one, several or all of the optical devices 3 . 7 . 9 . 12 to adjust to their needs. These then currently set values of the optical devices can in the evaluation and control unit 13 stored and used as desired setpoints for future adjustment operations.
