Description

The invention relates to a sun visor system for a driver's cab, a driver's cab with such a sun visor system for a motor vehicle, a motor vehicle with such a driver's cab, and a control method for such a sun visor system.

Sun visors for a driver's cab, for example a motor vehicle, are known in numerous embodiments, for example from US Pat DE 10 2006 009 251 A1 (Sun slide), EP 1 832 453 A1 (Sun blind) or the U.S. 5,076,633 (according to the state of the art cited therein as a hinged cover). The purpose of the sun visor is to protect the driver in the driver's cab from dazzling sunlight when the sun is low. A driver often feels uncomfortably restricted in his view of the sun visor and he will want to retract the sun visor when changing direction. The use of the sun visor is also only necessary, for example, depending on the seasons, for example in winter, or even then only at certain times of the day, for example in the morning and / or in the evening. The operation of the sun visor is therefore often unfamiliar and at the same time usually only has to be carried out while driving. With the increasing desire to automate the systems of a driver's cab, the sun visor is preferably motorized. The actuation of a further button provided for this in the multitude of buttons in a driver's cab is, however, not very intuitive and can lead to an unnecessary distraction of the driver, who, on the contrary, should remain undisturbed in his view of the driving situation by means of the sun visor.

Proceeding from this, the present invention is based on the object of at least partially overcoming the disadvantages known from the prior art. The features according to the invention emerge from the independent claims, for which advantageous configurations are shown in the dependent claims. The features of the claims can be combined in any technically meaningful manner, in which case the explanations from the following description and features from the figures, which include additional embodiments of the invention, can also be used.

• - eine Sonnenblende;
• - ein Aktor zum Bewegen der Sonnenblende zwischen einer ausgefahrenen Position und einer eingefahrenen Position, wobei ein vorbestimmter Teilbereich des Sichtfelds eines Nutzers in der ausgefahrenen Position von der Sonnenblende verschattet ist;
• - eine Steuereinheit zum entsprechenden Ansteuern des Aktors zum Bewegen der Sonnenblende:
  • - auf einen Ausfahrbefehl hin zu der ausgefahrenen Position, und
  • - auf einen Einfahrbefehl hin zu der eingefahrenen Position.

The invention relates to a sun visor system for a driver's cab, having at least the following components:

• - a sun visor;
• an actuator for moving the sun visor between an extended position and a retracted position, a predetermined sub-area of the field of view of a user being shaded by the sun visor in the extended position;
• - a control unit for the corresponding control of the actuator for moving the sun visor:
  • - upon an extend command to the extended position, and
  • - on an approach command to the retracted position.

The sun visor system is primarily characterized in that a movement sensor is also provided for detecting gestures by a user, with the movement sensor being able to detect a first gesture as an extension command and a second gesture as a retraction command for transmission to the control unit.

In the following, reference is made to the named axis of rotation if the axial direction, radial direction or the direction of rotation and corresponding terms are used without explicitly otherwise indicating. Unless explicitly stated otherwise, ordinal numbers used in the preceding and following description are only used for clear distinction and do not reflect any order or ranking of the components identified. An ordinal number greater than one does not necessarily mean that another such component must be present.

The sun visor system proposed here comprises a sun visor which preferably comprises two partial visors, namely for the driver and for the front passenger of a motor vehicle, the sun visor accomplishing the previously known task of shading a portion of the field of vision of a user in a driver's cab. The sun visor can be moved automatically between an extended position and a retracted position by means of an actuator, for example an electric motor, the field of view preferably being maximum in the retracted position and maximum desired shading being achieved in the extended position. The two positions are also referred to below as end positions and form the travel limit for the sun visor. In between, intermediate positions are preferably also permanently adjustable. A control unit is provided for the actuator, for example a control circuit board which, for example, is structurally integrated into the actuator or is connected to the actuator in a communicating manner. The control unit is an external unit or internal unit of the actuator. As an external unit, there is, for example, a further control unit and / or a further control unit in the actuator interposed. By means of the control unit, in response to an extension command, the sun visor is moved by the actuator to the extended position and, in response to a retraction command, is moved to the retracted position. For example, a certain current strength or voltage is output by the control unit in response to one of the two commands and, for example, when the actuator is designed as an electric motor, the current direction is reversed between the extend command and the retract command. Alternatively, a machine command is passed on from the control unit to a control unit of the actuator, for example two different direction commands and a switch-off command. In a further variant, the control unit specifies a path length which is converted by the control unit of the actuator into a corresponding movement of the sun visor.

It is proposed here that a motion sensor be provided which is set up to detect a plurality of gestures by a user, each gesture being assigned to a command, that is to say here the first gesture to the extend command and the second gesture to the retract command. For example, the respective gesture is a hand movement by the user, for example a downward wave (first gesture) to extend and an upward wave (second gesture) to raise. Alternatively, the respective gesture is a facial expression on the part of the user that is associated with (preferably simple) face recognition. In a particularly preferred embodiment, a plurality of individual gestures are possible for addressing the control unit, that is to say the respective gesture comprises a group of (preferably equivalent and / or identically acting) individual gestures, so that the operation of the sun visor system is particularly intuitive. The advantage here is that the sun visor system does not require an additional button and thus the distraction of the vehicle driver is low, and the time required to cause the sun visor to be extended or the sun visor to be retracted is very short.

It is also proposed in an advantageous embodiment of the sun visor system that the movement sensor comprises a proximity sensor.

A proximity sensor is, for example, optically, electromagnetically, based on ultrasound or capacitive, the approach of an object, in this case a part of the body of a user, for example the hand of a user, being detectable at least without the need for contact. An optical proximity sensor detects, for example, a sudden darkening by means of shading the incident light on a light sensor and uses it to detect the approach. An electromagnetic sensor detects, for example, a change in resistance in air or a reflection, the frequency of the electromagnetic radiation preferably in the range of the WLAN frequency according to IEEE 802.11 or the WPAN frequency (e.g. Bluetooth0) according to IEEE 802.15, the electromagnetic radiation of which is used in a driver's cab of a motor vehicle is usually present nowadays. In another embodiment, ultrasound is used, the reflections of the ultrasound wave on a part of the body of the user being recorded or their change and / or displacement. A capacitive proximity sensor detects the change in capacitance in its immediate vicinity of the proximity sensor, the change in electrical capacitance being detected by means of the reduction or first formation of an air gap between a part of the body of a user and the proximity sensor.

It is also proposed in an advantageous embodiment of the sun visor system that an active first pictogram and / or an active second pictogram are also provided, which are active before and / or when the sun visor is moved,
where the first icon lights up when an extension command has been received, and
the second pictogram lights up when an entry command has been received.

In this embodiment, the user is supported by active pictograms, the pictograms being set up to give the user feedback on the state of the sun visor in which the first pictogram lights up when an extension command has been received and the second icon lights up when an entry command has been received. In one embodiment, the respective pictogram lights up continuously as long as a driving movement is carried out and in an alternative embodiment only briefly when the command is entered, in order to only inform the user of the success of his input, possibly to bridge a time delay between the user inputting the command and the movement of the sun visor. In a preferred embodiment, a pictogram is set up to light up with different colors in order to give the user further feedback, for example to light up green if the input was successful or light up red if the input was unsuccessful or the sun visor is already in the end position corresponding to the command has taken. A pictogram is set up, for example, in such a way that it points in a spatial direction which (as far as possible) intuitively corresponds to the respective direction of movement of the sun visor. In a particularly preferred embodiment, a pictogram is arranged in such a way that its position is congruent with a proximity sensor in an embodiment according to the above description, particularly preferably an optical proximity sensor. Simplified operation is thus created for the user. In a particularly preferred embodiment, the pictograms are equipped with an (additional) sensor for detecting an angle of solar irradiation and / or a solar irradiation brightness, so that the pictograms light up as soon as an extension or retraction of the sun visor appears to be indicated. The user thus remains in control of the movement of the sun visor and does not become the victim of irradiation that is misinterpreted by means of a sun sensor, for example a (little or insufficiently disturbing) street lamp.

It is further proposed in an advantageous embodiment of the sun visor system that the sun visor comprises a sun blind or a sun slide.

A roller blind and a sun slider have the advantage that they do not protrude into the driver's cab when extending, compared to a folding screen, but can only be moved along thanks to a sliding track, for example along a viewing window such as a windshield or a vehicle door window. A sun blind has the advantage over a sun slider that, due to the fact that the cover material can be rolled up, particularly little installation space is required. A sun slide is advantageous, for example, with regard to a particularly simple guide for the movement of the sun slide. In the retracted position, the sun visor is preferably completely outside the field of vision, for example outside the area of the windshield or window of a vehicle door, for example stowed in a paneling of the driver's cab, for example in the vehicle roof.

In one embodiment as a roller blind, the obligatory make-up mirror in a driver's cab of a motor vehicle is preferably integrated into the rear-view mirror, the mirror pane forming the actual rear-view mirror being transparently switchable for the purpose of using the make-up mirror hidden behind it. The make-up mirror is preferably inclined to the driver or to the front passenger, deviating from the orientation of the actual rear-view mirror for self-observation.

According to a further aspect, a driver's cab for a motor vehicle is proposed having
a viewing window for a user, at least one A-pillar and one
Sun visor system according to an embodiment according to the description above,
wherein the motion sensor is preferably integrated into the cladding of at least one of the A-pillars of the driver's cab.

The driver's cab can preferably be used in a motor vehicle, particularly preferably in a passenger vehicle, and has a visually appealing panel facing a driver, that is to say the user of the sun visor system. A viewing window for the user, for example a windshield or the window of a vehicle door, is arranged in the user's field of vision and, if the worst comes to the worst, the viewing window can be suitably shaded by means of the sun visor of the sun visor system. For the construction of the driver's cab and preferably for the crash-safe passenger cell of the motor vehicle, at least one A-pillar, preferably two A-pillars, is provided, which is preferably arranged directly adjacent to the viewing window, for example the windshield. In a preferred embodiment, the movement sensor is integrated into the cladding of at least one of the A-pillars of the driver's cab, so that no component protrudes into the driver's cab and is at the same time arranged in the field of vision of the user. In a preferred embodiment, the movement sensor is a component of the cladding and is used together with the cladding when assembling the driver's cab or the motor vehicle.

According to a further aspect, a motor vehicle is proposed, having a plurality of propulsion wheels and a driver's cab according to an embodiment according to the description above,
an on-board computer preferably comprising the control unit of the sun visor system.

The motor vehicle proposed here is preferably a passenger car and the viewing window, the windshield and / or a pane in a vehicle door. The majority of the propulsion wheels, for example two or four, are set up to propel the motor vehicle and the driver's cab is integrated into the chassis of the motor vehicle. In a preferred embodiment, the control unit of the sun visor system is included in an on-board computer of the motor vehicle, for example a CAN bus, and the motion sensor and the actuator for the sun visor are connected to the on-board computer in a communicating manner for this purpose. In an alternative embodiment, the control unit is integrated as a unit in the motion sensor or in the actuator.

1. a. mittels des Bewegungssensors Überwachen eines definierten Raumbereichs, in welchem vorbestimmte Gesten erfassbar sind;
2. b. auf eine erste Geste hin, mittels des Bewegungssensors Ausgeben eines Ausfahrbefehls an die Steuereinheit des Sonnenblendensystems, und daraufhin mittels des Aktors Beginnen mit einem Ausfahren der Sonnenblende, wenn diese sich außerhalb der ausgefahrenen Position befindet;
3. c. auf eine zweite Geste hin, mittels des Bewegungssensors Ausgeben eines Einfahrbefehls an die Steuereinheit des Sonnenblendensystems, und daraufhin mittels des Aktors Beginnen mit einem Einfahren der Sonnenblende, wenn diese sich außerhalb der eingefahrenen Position befindet.

According to a further aspect there is provided a control method for a sun visor system according to an embodiment according to the above Description proposed, the control method comprising at least the following steps:

1. a. by means of the motion sensor, monitoring a defined spatial area in which predetermined gestures can be detected;
2. b. In response to a first gesture, by means of the movement sensor, issuing an extension command to the control unit of the sun visor system, and then by means of the actuator to start extending the sun visor if it is outside the extended position;
3. c. in response to a second gesture, by means of the movement sensor, issuing a retraction command to the control unit of the sun visor system, and then by means of the actuator to start retracting the sun visor if it is outside the retracted position.

A spatial area monitored by the motion sensor is, depending on the embodiment of the motion sensor, for example as a proximity sensor, only a few centimeters from the location of the motion sensor, for example the cladding of an A-pillar of the driver's cab, or the entire area in which a driver and / or a passenger has one Motor vehicle sits and / or a spatial area in the usual space of movement of the hands of a driver and / or a passenger of a motor vehicle. If the sun visor is already in the respective position in which it is to be moved in response to the associated gesture, the control unit preferably does not issue a command to the actuator or a stop prevents further movement of the sun visor in this corresponding direction. In a preferred embodiment, the user receives feedback about the failure of his gesture, for example acoustically or optically, for example by means of the pictograms as described above.

It is further proposed in an advantageous embodiment of the control method that at least one pictogram is provided according to an embodiment according to the description above,
where before and / or in step b. the first pictogram lights up; and / or wherein before and / or in step c. the second pictogram lights up.

If the respective pictogram only lights up in front of the respective step, this is used to report back to the user that the command was successfully received or if his gesture was misinterpreted. If the pictogram lights up while the respective step is being carried out, the user is informed that the sun visor has not yet been fully extended or not fully retracted. In an alternative embodiment, the respective pictogram lights up when the respective end position is reached.

It is also proposed in an advantageous embodiment of the control method that during an extension by means of the actuator of the sun visor, as a result of detection with the motion sensor of the second gesture or the first gesture repeated after an interruption, the extension is stopped and the sun visor is held in the current position is, and / or during retraction by means of the actuator of the sun visor, as a result of detection with the motion sensor of the first gesture or the second gesture repeated after an interruption, the retraction is stopped and the sun visor is held in the current position.

On the one hand, it is desired that the user has to spend as little effort as possible in order to extend or retract the sun visor, but at the same time it is often desirable that the sun visor can assume intermediate positions. For example, a single gesture, limited to a short time, is necessary to cover the full distance so that the respective end position is assumed by the sun visor. In order to hold an intermediate position, it is proposed here that the respective other gesture or repeatedly the same gesture stop the movement so that the sun visor remains in the current position, that is to say it assumes an intermediate position.

It is further proposed in an advantageous embodiment of the control method that the first gesture and / or the second gesture must be detected by the movement sensor during the entire duration of the process of extending or retracting by means of the actuator of the sun visor, and / or
the first gesture and / or the second gesture for complete extension into the extended position or for complete retraction into the retracted position must be detected twice by the motion sensor by means of the actuator of the sun visor with one interruption,
wherein the sun visor preferably comprises a first partial visor and a second partial visor, and only as a result of detection by means of the movement sensor of a third gesture is one of the partial visors of the sun visor moved and / or transferred into the same position as the other partial visor.

In one embodiment it is proposed that the user must display the gesture permanently and as soon as the user no longer shows the gesture, the movement of the sun visor is stopped and the sun visor remains in the current one Position. The sun visor is therefore only moved as long as the respective gesture is displayed by the user or detected by the motion sensor.

In a supplementary or alternative embodiment, it is proposed here that to fully extend or fully retract the sun visor, the respective gesture must be shown twice, with it being recorded twice when there is an interruption in the detection of the gesture, preferably with an interruption of a minimum duration , for example of at least a tenth of a second. In the case of a dynamic gesture, for example waving the hand, the return to the starting position of the dynamic gesture is interpreted as an interruption, this return, for example, corresponding to the other gesture, for example an upward wave as a second gesture between the two downward waves as the first gesture.

Regardless of the rest of the control method, it is proposed here that the sun visor comprises a first partial visor and a second partial visor, for example for the driver and front passenger, which can be operated via a common movement sensor or via two or more movement sensors acting as a common unit. For example, only the first partial screen is normally moved via a first movement sensor, which is assigned to the first partial screen, but when a third gesture is entered (before, after or at the same time as the first gesture or the second gesture), the second partial screen is also moved. This process can preferably also be carried out the other way round, by means of a second movement sensor which is assigned to the second partial screen, unless a (preferably identical) third gesture is entered. In a particularly preferred embodiment, the respective other partial screen is transferred in a different present position by means of a third gesture into the same position of the partial screen moved shortly before and / or moved by means of the respective other movement sensor. In one embodiment, only one movement sensor is provided for both partial diaphragms, preferably one movement sensor is provided for each partial diaphragm, particularly preferably each with separate pictograms.

The control method can preferably be carried out by an on-board computer of a motor vehicle, a control unit of the sun visor system.

According to a further aspect, the invention relates to a computer program comprising computer program code, the computer program code being executable on a computer in such a way that the computer is prompted to carry out the method according to an embodiment according to the description above,
wherein the computer is preferably in an on-board computer of a motor vehicle
is integrated, wherein the motor vehicle is preferably designed according to an embodiment according to the above description.

According to this embodiment, the control method described here is implemented in a computer-implemented manner. The computer-implemented method is stored as computer program code, the computer program code, when it is executed on a computer, causing the computer to carry out the control method according to an embodiment according to the preceding description.

The same definitions and examples of embodiments as have already been listed above apply to the computer program and the control method carried out.

The computer-implemented method is realized, for example, by a computer program, the computer program comprising computer program code, the computer program code, when executed on a computer, causing the computer to execute the control method according to an embodiment as described above. Computer program code is synonymous with one or more instructions or commands that cause a computer or processor to carry out a series of operations that represent, for example, an algorithm and / or other processing methods.

The computer program can preferably be partially or completely executed on a handheld device, for example a so-called smartphone and / or on an on-board computer. In the case of an embodiment on a handheld, the motion sensor is preferably designed analogously as described above, and the control unit is also preferably a component of the handheld and the actuator comprises only one control unit or, for other control, is parallel to it with a further control unit, preferably as described above, fitted.

According to a further aspect, the invention relates to a computer program product on which a computer program code is stored, wherein the computer program code can be executed on a computer in such a way that the computer is prompted to carry out the control method according to an embodiment according to the description above,
wherein the computer is preferably integrated in an on-board computer of a motor vehicle, wherein the motor vehicle is preferably designed according to an embodiment according to the description above.

A medium such as RAM, ROM, an SD card, a memory card, a flash memory card or a disc, or stored on a server and can be downloaded, for example, is a computer program product containing computer program code. If the computer program is made readable via a read-out unit, for example a drive and / or an installation, the computer program code contained and the method contained therein can be executed by a computer or in communication with a plurality of processing units, for example as described above.

Communication in this context means the transmission of predetermined forms of analog or digital signals, the signals being set up solely for the exchange of information or also enabling power output, for example as a control current for an electrical machine. Communication is wired or contactless over a distance, called wireless or wireless, possible. Wireless communication is preferably carried out within the framework of standards in accordance with IEEE 802.11 and / or IEEE 802.15.

In 1 is a sun visor system 1 with a sun visor 3 in a side sectional view used in a driver's cab 2 shown. The sun visor system 1 includes a sun visor 3 , which here as a roller blind 14th or as a sun slide 15th is carried out and by means of an actuator 4th , automated between an extended position 5 and a retracted position 6th is movable. A control unit 8th communicates with the actuator 4th tied together. By means of the control unit 8th is the sun visor in response to an extension command 3 by means of the actuator 4th along an extension direction 26th towards an extended position 6th and in response to a retraction command (along one of the extension directions 26th opposite retraction direction) to the retracted position 5 movable (compare 8th ). The field of view is in the extended position 7th of the driver 27 and / or the front passenger partially covered and thus suitably shaded.

In 2 is a sun visor system 1 with a sun visor 3 in a side sectional view used in a driver's cab 2 shown. In contrast to 1 is the sun visor 3 here as a hinged cover 16 executed. For the rest, reference is made to the previous description.

In 3 is a sun visor 3 or a partial aperture 23 , 24 designed as a roller blind 14th shown. When the sun blind is moved 14th in the direction of extension 26th the sun visor material is unwound from a roll and thus forms a shade. To do this, a shaft of an actuator is used 4th , preferably an electric drive machine, by means of the control unit 8th set in rotation.

In 4th is a sun visor system 1 in a section of a driver's cab 2 shown in a top view. The illustration shows a viewing window 18th , here a windshield of a motor vehicle 17th (compare 1 ), from above. At the outer edge of the viewing window 18th the viewing window is on the left or right 18th as well as the driver's cab 2 each from an A-pillar 19th limited. In the middle is a rearview mirror 28 shown. The sun visor 3 includes to the left of the rearview mirror 28 a partial driver screen 23 and to the right of it a partial passenger screen 24 arranged, which here, for example, as hinged panels 16 are executed.

In 5 is the same view of a sun visor system 1 as in 4th shown. The difference is the sun visor 3 here as Sun blind 14th executed. For the rest, reference is made to the previous description.

In 6th is a sun visor system 1 in an interior view from the driver's cab 2 shown out. The representation corresponds to a section of the field of view 7th of the driver 27 (compare 9 ) and the passenger. Left of the rearview mirror 28 is the (driver) partial screen 23 as a hinged cover 16 and to the right of the rearview mirror 28 is the (front passenger) partial cover 24 as a roller blind 14th executed. This is used solely for the purpose of comparing the arrangement of the vanity mirror 29 which is on the left in the hinged panel 16 is integrated and on the right in the rearview mirror 28 behind the mirror pane 30th is hidden and inclined towards the respective user (here the passenger). Both partial diaphragms are preferred 23 , 24 executed similarly.

In 7th is partially a sun visor system 1 in a section of a driver's cab 2 with an A-pillar 19th shown from an interior view.

As shown to the right of the A-pillar 19th is a viewing window 18th , for example a windshield, in the field of view 7th of a driver 27 (compare 9 ) arranged. The A-pillar 19th has a first pictogram 12th for an extension towards the extended position 5 and a second pictogram 13th for a retraction towards the retracted position 6th (compare 8th ) on. A motion sensor 9 is used to capture gestures 10 , 11 , 25th (compare 8th ) of a user below the pictograms 12th , 13th arranged, preferably as a proximity sensor. If the hand of the user follows the first pictogram 12th approaches, this will be the first gesture 10 recorded. If the hand of the user follows the second pictogram 13th approaching, this is used as the second gesture 11 recorded. The corresponding command is sent to the control unit 8th of the sun visor system 1 passed on (compare 1 or 2 ).

In 8th Figure 13 is a timing diagram with a horizontal time axis 31 shown, with the current position of the sun visor 3 of the sun visor system 1 between the retracted position 6th and the extended position 5 at the bottom of the timeline 31 with a curve with a solid line for a first partial aperture 23 (for example the driver 27 ) and a dashed curve for a second partial diaphragm (for example, the front passenger) is shown. Steps a. to d.2 shown in the respective chronological order. Step a. is the monitoring of the driver's cab 2 (compare 9 ) to show gestures 10 , 11 , 25th . Step a. runs continuously. Step b. corresponds to displaying the first gesture 10 (Extend), step c. displaying the second gesture 11 (Retract), step d.1 corresponds to displaying the third gesture 25th by a user (e.g. the driver 27 ) and step d.2 corresponds to displaying the third gesture 25th from another user (e.g. the passenger). The pictograms are also lit up 12th , 13th , such as in 7th shown, represented, each with the corresponding step or the corresponding gesture 10 , 11 , 25th assigned just below. The sequence shown here only shows any selection of the previously described variants of the control method and any command sequence from a user (for example the driver 27 ). For example, this control method is used with a sun visor system 1 executed according to an embodiment according to the preceding figures and reference is made to the description there or to the general description for a more detailed explanation.

First of all, here are both partial apertures 23 , 24 in the retracted position 6th . Then the first gesture 10 displayed by the user and in step b. recognized. Right from the start of displaying the first gesture 10 the first pictogram lights up 12th on. The first gesture 10 but a predetermined minimum time must be kept, for example 3 tenths of a second, before the control unit 8th gives an extension command and the first partial aperture 23 toward the extended position 5 is moved (compare solid curve). The first pictogram shows 12th another signal, for example a different color, for example it changes from blue to green. The user now shows a third gesture in parallel 25th which is recognized in step d.1. The third gesture 25th but must also be held a predetermined minimum time before the control unit 8th gives an extension command and the second partial shutter 24 toward the extended position 5 is moved (compare dashed curve). A third pictogram 32 of the other user (for example the passenger) lights up, which for example the first pictogram 12th of the (first) user and / or the first pictogram 12th shows a changed signal again. The (first) user decides that the sun visor 3 should stop in a current position and show the first gesture 10 repeatedly. This is done immediately with a changed signal in the first pictogram 12th reflected and immediately in a stop command for both partial diaphragms 23 , 24 implemented, the second pictogram 13th lights up briefly once the stop command is detected. The stop command is for the second partial aperture 24 only implemented for the time when the same intermediate position 22nd is reached, which is the first partial diaphragm 23 as a result of the immediate response to the stop command. The first pictogram shows the phase in which the first partial aperture 23 already stands and the second partial aperture 24 a changed signal comes out even further.

After a while, the user wants the first partial aperture 23 drive in again and show the second gesture 11 which is analogous to the first gesture 10 a command sequence and signal sequence, however, on the second pictogram 13th causes. The first partial aperture 23 is in the retracted position 6th emotional. The second partial aperture 24 remains in the intermediate position 22nd because neither does the user make a third gesture 25th According to step d.2, another user (for example the passenger) shows a second gesture 11 shows.
