Description

[0001] 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.

[0002] Sun visors for a driver's cab, for example in a motor vehicle, are known in numerous embodiments, such as from DE 10 2006 009 251 A1 (sun slider), EP 1 832 453 A1 (sun roller blind) or US 5,076,633 (according to the prior art cited therein, as a folding visor). The purpose of the sun visor is to protect the driver in the cab from glare when the sun is low in the sky. Often, a driver feels their view is uncomfortably restricted by the sun visor and will want to retract it when changing direction. Furthermore, the use of the sun visor may only be necessary depending on the season, for example in winter, or even then only at certain times of day, for example in the morning and / or evening. Operating the sun visor is therefore often unfamiliar and usually has to be done while driving.With the increasing demand for automated driver's cab systems, motorized sun visors are a popular choice. However, operating yet another button among the many buttons in a driver's cab is not very intuitive and can lead to unnecessary driver distraction, since the sun visor is intended to ensure an unobstructed view of the road.

[0003] Based on this, the present invention aims to overcome, at least partially, the disadvantages known from the prior art. The features of the invention are defined in the independent claims, for which advantageous embodiments are shown in the dependent claims. The features of the claims can be combined in any technically meaningful way, whereby the explanations in the following description and features from the figures, which comprise supplementary embodiments of the invention, can also be used.

[0004] The invention relates to a sun visor system for a driver's cab, comprising at least the following components: - a sun visor; - an actuator for moving the sun visor between an extended position and a retracted position, wherein a predetermined portion of a user's field of vision is shaded by the sun visor in the extended position; - a control unit for controlling the actuator to move the sun visor: - upon receiving an extension command to the extended position, and - in response to a retraction command to the retracted position.

[0005] The sunshade system is characterized primarily by the fact that a motion sensor is still provided to detect user gestures, whereby a first gesture can be detected by the motion sensor as an extension command and a second gesture as a retraction command for transmission to the control unit.

[0006] The following text refers to the aforementioned axis of rotation whenever the axial direction, radial direction, or direction of rotation and corresponding terms are used, unless explicitly stated otherwise. Ordinal numbers used in the preceding and subsequent descriptions serve solely for unambiguous identification and do not indicate any order or ranking of the components referred to. An ordinal number greater than one does not necessarily imply the presence of another such component.

[0007] The proposed sun visor system comprises a sun visor, preferably with two sections, one for the driver and one for the front passenger of a motor vehicle. The sun visor performs the known function of shading a portion of a user's field of vision in a driver's cabin. The sun visor is automatically movable between an extended and a retracted position by means of an actuator, for example, an electric motor. Preferably, the retracted position maximizes the field of vision, while the extended position achieves the desired maximum shading. These two positions are hereinafter referred to as end positions and define the travel limits for the sun visor. Preferably, intermediate positions can also be permanently set between these positions.The actuator requires a control unit, such as a control circuit board, which may be integrated into the actuator or connected to it via communication. The control unit can be an external or internal component of the actuator. For example, an additional control unit and / or another control unit may be connected between the actuator and the actuator. Upon receiving an extension command, the control unit moves the sunshade from the actuator to the extended position, and upon receiving a retraction command, it moves it to the retracted position. For example, the control unit outputs a specific current or voltage in response to one of the two commands. In the case of an electric motor, this current is reversed between the extension and retraction commands.Alternatively, the control unit transmits a machine command to a control unit of the actuator, for example, two different direction commands and a switch-off command. In another variant, the control unit specifies a path length, which is then translated by the control unit of the actuator into a corresponding movement of the sun visor.

[0008] It is proposed here that a motion sensor be provided which is configured to detect multiple user gestures, with each gesture being assigned to a command; in this case, the first gesture to the extension command and the second gesture to the retraction command. For example, each gesture could be a hand movement by the user, such as a downward wave (first gesture) to extend and an upward wave (second gesture) to raise. Alternatively, each gesture could be a facial expression of the user, thus combined with (preferably simple) facial recognition. In a particularly preferred embodiment, multiple individual gestures are possible for addressing the control unit; that is, each gesture comprises a group of (preferably equivalent and / or equivalent) individual gestures, making the operation of the sunshade system particularly intuitive.The advantage here is that the sun visor system does not require an additional button, thus minimizing driver distraction, and the time required to extend or retract the sun visor is very short.

[0009] In a further advantageous embodiment of the sun visor system, it is proposed that the motion sensor includes a proximity sensor.

[0010] A proximity sensor can be optical, electromagnetic, ultrasonic, or capacitive, for example, and detects the approach of an object—in this case, a user's body part, such as a user's hand—at least without the need for physical contact. An optical proximity sensor, for instance, detects a sudden darkening by obscuring the light falling on a light sensor and thus recognizes the approach. An electromagnetic sensor, for example, detects a change in resistance in air or a reflection, with the frequency of the electromagnetic radiation preferably being in the range of the WLAN frequency according to IEEE 802.11 or the WPAN frequency (e.g., Bluetooth 0) according to IEEE 802.15, the electromagnetic radiation of which is commonly present in the cabin of a motor vehicle today.In another embodiment, ultrasound is used, whereby the reflections of the ultrasound wave at a part of the user's body are detected, or rather their change and / or displacement. A capacitive proximity sensor detects the change in capacitance in its immediate vicinity, whereby the change in electrical capacitance is detected by means of the reduction or formation of an air gap between a part of the user's body and the proximity sensor.

[0011] In an advantageous embodiment of the sun visor system, it is further proposed that an active first pictogram and / or an active second pictogram be provided, which are active before and / or when the sun visor is moved. the first pictogram lights up when an exit command has been received, and The second pictogram lights up when an entry command has been received.

[0012] In this embodiment, the user is supported by active pictograms, which are designed to provide feedback on the status of the sun visor. The first pictogram illuminates when an extension command is received, and the second pictogram illuminates when a retraction command is received. In one embodiment, the respective pictogram illuminates continuously while a movement is being executed, and in an alternative embodiment, it illuminates only briefly upon command input, thus merely informing the user of the success of their input, possibly to bridge a time delay between the user entering the command and the movement of the sun visor.In a preferred embodiment, a pictogram is configured to illuminate in different colors to provide the user with further feedback, for example, illuminating green if the input was successful or red if the input was unsuccessful or the sun visor has already reached the end position corresponding to the command. The pictogram is, for example, configured to point in a spatial direction that (ideally) intuitively corresponds to the respective direction of movement of the sun visor. In a particularly preferred embodiment, the pictogram is arranged such that its position is always congruent with a proximity sensor in an embodiment according to the above description, particularly preferably an optical proximity sensor. This simplifies operation for the user.In a particularly preferred embodiment, the pictograms are equipped with an (additional) sensor for detecting the angle and / or intensity of sunlight, so that the pictograms light up as soon as the sun visor appears to be extending or retracting. The user thus retains control over the movement of the sun visor and is not affected by sunlight misinterpreted by a sun sensor, for example, from a (lightly or insufficiently disruptive) streetlamp.

[0013] In a further advantageous embodiment of the sunshade system, it is proposed that the sunshade comprises a sun blind or a sun slider.

[0014] A sunshade roller blind and a sun visor slider have the advantage that, unlike a folding visor, they do not protrude into the driver's cabin when extended. Instead, they are simply moved along a sliding track, for example, along a viewing window such as a windshield or a door window. A sunshade roller blind has the advantage over a sun visor slider that, due to the rollable design of the material, it requires very little installation space. A sun visor slider, for example, is advantageous due to its particularly simple guide mechanism. Ideally, when retracted, the sunshade is completely outside the driver's field of vision, for example, outside the area of ​​the windshield or a door window, and is stored, for instance, in a cabin lining, such as the headliner.

[0015] In one embodiment, a sunshade, the mandatory vanity mirror in the driver's cabin of a motor vehicle is preferably integrated into the rearview mirror, wherein the mirror pane forming the actual rearview mirror can be switched to transparent for the purpose of using the vanity mirror concealed behind it. The vanity mirror is preferably inclined towards the driver or passenger for self-viewing, unlike the orientation of the actual rearview mirror.

[0016] According to another aspect, a driver's cab for a motor vehicle is proposed, featuring a viewing window for a user, at least an A-pillar and a Sun visor system according to an embodiment as described above, preferably the motion sensor is integrated into the trim of at least one of the A-pillars of the driver's cabin.

[0017] The driver's cab is preferably used in a motor vehicle, particularly preferably in a passenger vehicle, and features an aesthetically pleasing enclosure facing the driver, i.e., the user of the sun visor system. A viewing window for the user, for example, a windshield or a door window, is positioned within the user's field of vision, and if necessary, this window can be appropriately 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-resistant passenger cell of the motor vehicle, at least one A-pillar, preferably two A-pillars, is provided, which is preferably positioned directly adjacent to the viewing window, for example, the windshield.In a preferred embodiment, the motion sensor is integrated into the trim of at least one of the A-pillars of the driver's cabin, so that no component protrudes into the cabin and it is simultaneously located within the user's field of vision. In a preferred embodiment, the motion sensor is a component of the trim and is installed together with the trim during the assembly of the driver's cabin or the vehicle.

[0018] According to another aspect, a motor vehicle is proposed, comprising a plurality of drive wheels and a driver's cabin according to an embodiment as described above. preferably an on-board computer includes the control unit of the sun visor system.

[0019] The proposed motor vehicle is preferably a passenger car, and the viewing window is the windshield and / or a window in a vehicle door. The majority of the drive wheels, for example two or four, are configured to propel the vehicle, and the driver's cabin is integrated into the vehicle's chassis. In a preferred embodiment, the control unit for the sun visor system is included in the vehicle's on-board computer, for example, a CAN bus, and the motion sensor and the actuator for the sun visor are connected to the on-board computer for this purpose. In an alternative embodiment, the control unit is integrated as a single unit into the motion sensor or the actuator.

[0020] According to another aspect, a control method for a sun visor system according to an embodiment as described above is proposed, wherein the control method includes at least the following steps: a. using the motion sensor to monitor a defined area of ​​space in which predetermined gestures can be detected; b. in response to an initial gesture, the motion sensor sends an extension command to the control unit of the sun visor system, and then the actuator begins extending the sun visor when it is outside the extended position; c. upon a second gesture, the motion sensor issues a retraction command to the control unit of the sun visor system, and then the actuator begins retracting the sun visor if it is outside the retracted position.

[0021] Depending on the motion sensor's design (e.g., as a proximity sensor), the monitored area is either just a few centimeters from its mounting location (e.g., the trim of an A-pillar in the driver's cabin), or the entire area in which a driver and / or passenger of a vehicle sits, and / or an area within the typical range of motion of a driver's and / or passenger's hands. If the sun visor is already in the position to which it is to be moved by the corresponding gesture, the control unit preferably does not issue a command to the actuator, or a stop prevents further movement of the sun visor in that direction.In a preferred embodiment, the user receives feedback on the failure of his gesture, for example acoustically or visually, for example by means of the pictograms as described above.

[0022] It is further proposed in an advantageous embodiment of the control method that at least one pictogram is provided according to an embodiment as described above. where the first pictogram lights up before and / or during step b; and / or where the second pictogram lights up before and / or during step c.

[0023] If the respective pictogram only lights up before the respective step, this serves as feedback to the user that the command was successfully received or if their gesture was misinterpreted. If the pictogram lights up during the execution of the respective step, the user is informed that the sun visor is not yet fully extended or retracted. In an alternative embodiment, the respective pictogram lights up when the respective end position is reached.

[0024] In a further advantageous embodiment of the control method, it is proposed that during extension by means of the sun visor actuator, as a result of detection by the motion sensor of the second gesture or of the first gesture repeated after an interruption, the extension is stopped and the sun visor is held in the current position, and / or during retraction by means of the sun visor actuator, as a result of detection by the motion sensor of the first gesture or of the second gesture repeated after an interruption, the retraction is stopped and the sun visor is held in the current position.

[0025] On the one hand, it is desirable that the user has to exert as little effort as possible to extend or retract the sun visor; on the other hand, it is often desirable for the sun visor to be able to assume intermediate positions. For example, a single, brief gesture is needed to travel the full range of motion, so that the sun visor reaches the desired end position. To hold an intermediate position, it is suggested that the other gesture, or repeating the same gesture, stops the movement, so that the sun visor remains in its current position, thus holding an intermediate position.

[0026] In a further advantageous embodiment of the control method, it is proposed that the motion sensor must detect the first gesture and / or the second gesture throughout the entire duration of the process of extending or retracting the sun visor by means of the actuator, and / or The motion sensor must detect the first gesture and / or the second gesture for fully extending the sun visor into the extended position or fully retracting it into the retracted position by means of the sun visor actuator twice with an interruption. wherein preferably the sun visor comprises a first partial visor and a second partial visor, and only as a result of detection by means of the motion sensor of a third gesture is one of the partial visors of the sun visor moved and / or transferred to the same position as the other partial visor.

[0027] In one embodiment, it is proposed that the user must continuously display the gesture, and as soon as the user ceases to display the gesture, the movement of the sun visor is stopped and the sun visor remains in its current position. Thus, the sun visor only moves as long as the respective gesture is displayed by the user or detected by the motion sensor.

[0028] In a supplementary or alternative embodiment, it is proposed here that the respective gesture must be performed twice for the sun visor to be fully extended or fully retracted. A gesture is considered to have been performed twice if there is an interruption in its detection, preferably with an interruption of minimal duration, for example, at least one-tenth of a second. In the case of a dynamic gesture, such as waving the hand, the return to the initial position of the dynamic gesture is interpreted as an interruption. This return corresponds, for example, to the other gesture, such as an upward wave as the second gesture between the two downward waves as the first gesture.

[0029] Regardless of the other control methods, it is proposed here that the sun visor comprises a first sub-visor and a second sub-visor, for example, for the driver and the front passenger, which can be operated via a common motion sensor or via two or more motion sensors acting as a single unit. For example, a first motion sensor assigned to the first sub-visor normally moves only the first sub-visor; however, if a third gesture is entered (before, after, or simultaneously with the first or second gesture, respectively), the second sub-visor is also moved. This process can preferably also be executed in reverse, using a second motion sensor assigned to the second sub-visor, provided that no (preferably identical) third gesture is entered.In a particularly preferred embodiment, the other partial aperture, when in a different position, is moved by means of a third gesture into the same position as the partial aperture that was moved shortly before and / or moved by means of the other motion sensor. In one embodiment, only one motion sensor is provided for both partial apertures; preferably, one motion sensor is provided for each partial aperture, particularly preferably with separate pictograms.

[0030] The control procedure is preferably executable by an on-board computer of a motor vehicle, a control unit of the sun visor system.

[0031] According to a further aspect, the invention relates to a computer program comprising computer program code, wherein the computer program code is executable on a computer in such a way that the computer is caused to execute the method according to an embodiment as described above. wherein the computer is preferably in an on-board computer of a motor vehicle is integrated, preferably the motor vehicle being designed according to an embodiment as described above.

[0032] The control method described here is implemented in a computer according to this embodiment. The computer-implemented method is stored as computer program code, wherein the computer program code, when executed on a computer, causes the computer to execute the control method according to an embodiment as described above.

[0033] The same definitions and examples of embodiments apply to the computer program and the executed control procedure as those already listed above.

[0034] The computer-implemented method is realized, for example, by a computer program, wherein the computer program comprises computer program code, and wherein the computer program code, when executed on a computer, causes the computer to execute the control method according to an embodiment as described above. Computer program code is synonymously defined as one or more instructions or commands that cause a computer or processor to perform a series of operations, which, for example, constitute an algorithm and / or other processing methods.

[0035] The computer program is preferably partially or completely executable on a handheld device, for example a so-called smartphone, and / or on an on-board computer. In the case of a handheld implementation, the motion sensor, preferably designed analogously to the one described above, and preferably also the control unit, are components of the handheld device, and the actuator comprises only a control unit or, for alternative control, is equipped in parallel with another control unit, preferably as described above.

[0036] 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 is executable on a computer in such a way that the computer is caused to execute the control method according to an embodiment as described above. wherein the computer is preferably integrated into an on-board computer of a motor vehicle, wherein the motor vehicle is preferably designed according to an embodiment as described above.

[0037] A computer program product, comprising computer program code, is stored on a medium such as RAM, ROM, an SD card, a memory card, a flash memory card, or a disc, or on a server and is downloadable. If the computer program is made readable via a read device, such as a drive and / or an installation, then the contained computer program code and the procedure contained therein are executable by a computer or in communication with a plurality of computing units, for example, as described above.

[0038] In this context, communication means the transmission of predetermined forms of analog or digital signals, where the signals are solely for information exchange or also enable power output, for example, as control current for an electric machine. Communication can be wired or wireless over a distance. Wireless communication is preferably conducted within the framework of standards according to IEEE 802.11 and / or IEEE 802.15.

The A-pillar 19 A first pictogram 12 for extending in the direction towards the extended position 5 and a second pictogram 13 for moving in the direction towards the moved-in position 6 (compare Fig. 8) on. A motion sensor 9 is for capturing gestures 10 , 11 , 25 (compare Fig. 8) a user below the pictograms 12 , 13 Arranged, preferably as a proximity sensor. When the user's hand moves towards the first pictogram 12 as they approach, this will be their first gesture 10 detected. If the user's hand moves towards the second pictogram 13 as it approaches, this is seen as a second gesture 11 The data is captured. The corresponding command is sent to the control unit. 8of the sun visor system 1 passed on (compare Fig. 1 or Fig. 2).

[0048] In Fig. Figure 8 is a time 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 6 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's) 27 ) and a dashed curve for a second partial view (for example, of the passenger). Above this, steps a. to d.2 are shown in their respective chronological order, each in a separate line. Step a. is the monitoring of the driver's cab. 2 (compare Fig. 9) on displaying gestures 10 , 11 , 25Step a. is executed continuously. Step b. corresponds to displaying the first gesture. 10 (Exit), step c. the display of the second gesture 11 (Entering), step d.1 corresponds to displaying the third gesture 25 from a user (for example, the driver) 27 ) and step d.2 corresponds to displaying the third gesture 25 from another user (for example, the passenger). Furthermore, the pictograms may light up. 12 , 13 , as for example in Fig. 7 shown, depicted, each corresponding step or gesture 10 , 11 , 25 assigned just below. The sequence shown here merely illustrates an arbitrary selection of the previously described variants of the control procedure, as well as an arbitrary sequence of commands from a user (for example, the driver). 27For example, this control method is used with a sun visor system. 1 carried out according to an embodiment as shown in the preceding figures, and reference is made to the description therein or to the general description for further explanation.

[0049] First, here are both partial apertures. 23 , 24 in the retracted position 6 Then the first gesture 10 displayed by the user and recognized in step b. This occurs from the very beginning of the display of the first gesture. 10 The first pictogram lights up 12 up. The first gesture 10 However, a predetermined minimum time must be maintained, for example 3 tenths of a second, before the control unit 8 gives an extension command and the first partial aperture 23 in the direction of the extended position 5 is being moved (compare solid curve). The first pictogram shows this. 12A different signal is displayed, for example, a different color, for instance, changing from blue to green. The user then simultaneously displays a third gesture. 25 the third gesture, which is recognized in step d.1. 25 However, a predetermined minimum time must also be maintained before the control unit 8 gives an extension command and the second partial aperture 24 in the direction of the extended position 5 is being moved (compare the dashed curve). A third pictogram 32 The other user's (for example, the passenger's) indicator lights up, which corresponds, for example, to the first pictogram. 12 corresponds to the (first) user, and / or the first pictogram 12 It shows a changed signal again. The (first) user decides that the sun visor 3 should remain in its current position and demonstrates the first gesture. 10This is repeated. This is immediately accompanied by a change in the signal of the first pictogram. 12 reflected and immediately converted into a stop command for both partial apertures 23 , 24 implemented, the second pictogram 13 The light briefly illuminates upon detection of the stop command. The stop command is used for the second partial aperture. 24 only implemented for the time when the same intermediate position 22 is reached, which is the first partial aperture 23 as a result of the immediate reaction to the stop command. The first pictogram shows the phase in which the first partial aperture is closed. 23 already in place and the second partial aperture 24 If it extends even further, it sends a different signal.

[0050] After a while, the user wants to open the first partial aperture. 23 retract and displays the second gesture 11 , which is analogous to the first gesture 10However, a sequence of commands and signals is indicated by the second pictogram. 13 This causes the first partial aperture. 23 is moved into the locked position 6 moved. The second partial aperture 24 remains in the intermediate position 22 , because neither the user nor a third gesture 25 According to step d.2, another user (for example, the passenger) shows a second gesture. 11 shows. For example, when leaving the driver's cab 2 the second partial aperture 24 automatically returns to the locked position 6 transferred.

[0051] In Fig. 9 is a section of a motor vehicle 17 shown in a sectional view. The motor vehicle 17 is shown here as a passenger car and the viewing window 18 in the field of vision 7 the driver 27 The windshield. A drive wheel. 20(here, for example, a front wheel) is in front of the driver's cab 2 arranged and the driver's cab 2 is integrated into the chassis of the motor vehicle 17 between an underbody 33 and a vehicle sky 34 integrated. The driver's cab 2 includes a seat 35 for the driver 27 and a steering wheel 36 and much more that is not shown or described here.

[0052] The motor vehicle 17 includes an on-board computer 21 , which is equipped with a control unit 8 of the sun visor system 1 is connected in a communicating manner.
