Description

OPTICAL ARRANGEMENT, VEHICLE AND PROCEDURE

DESCRIPTION

The invention is based on an optical arrangement with at least one projector and with at least one disk. Furthermore, the invention is based on a vehicle with the optical arrangement and a method with the optical arrangement.

A projection of image content in glass panes is a topic that is the subject of development projects, especially in the automotive industry. For example, a switchable vehicle window can be provided which can be switched between transparent and milk white, that is to say opaque, and which can be used in the opaque state as a projection screen and / or projection screen. A projector in the vehicle can display a light image on the opaque vehicle window. If this function is not required, the window is transparent like a conventional vehicle window.

In addition, a projector can be arranged in the outer area of a body of a vehicle, for example in doors, side mirrors or sills, in order, for example, to display a welcome message for a driver of the vehicle on the ground in front of the vehicle. This projector can also be used to project advertising messages for passers-by.

One object of the invention is to create a simple and inexpensive optical arrangement with a projector in terms of device technology, via which light images can be displayed in two projection planes. Another task be the invention is to create a device-technically simple and inexpensive vehicle with the optical to order. In addition, it is a further task of the invention to create a simple and inexpensive method with the optical arrangement.

The object with regard to the optical arrangement is achieved according to the features of claim 1. The object with regard to the vehicle is achieved according to the features of claim 6 and the object with regard to the method is achieved according to the features of claim 9.

Particularly advantageous configurations can be found in the dependent claims.

According to the invention, an optical arrangement with at least one projector or one projection module is provided. Static or moving light images can be generated via the projector. Furthermore, the optical arrangement has at least one disk. The disk can be made very thin so that it corresponds to a film. The pane can, for example, be a vehicle pane or a shop window. Furthermore, the pane preferably has the property that it can be switched back and forth at least partially or in sections between a transparent state and an opaque, ie milky white, state. The pane and the projector are arranged in such a way that the pane can be irradiated by the projector. If the pane is switched to opaque, it is possible for the projector to display a light image on the pane. In other words, the projector can project a projection onto the opaque pane. Is the glass trans- switched parent, it is possible for the projector to display a light image through the pane on a projection surface. If the window is, for example, a vehicle window, it is possible for the projection surface to be a plane, for example a street, on which the vehicle is located. It is also possible that the projection surface is an outer surface, for example an engine hood, of the vehicle, which can have the optical-specific arrangement. Furthermore, the optical arrangement has at least one control. The control is configured in such a way that it can be used to switch the pane to be transparent and opaque and that it can be used to adapt the light image projected by the projector as a function of a switching state of the pane. Additionally or alternatively, the control can also change the switching state of the pane as a function of the projected light image. This means that the screen and the projector can be controlled via the control system depending on one another. One advantage of this invention is that the control can be used to adapt the light image projected via the projector in such a way that the projection, ie the light image, is optimally aligned on the pane or the projection surface. That is to say, the light image can be adapted, for example, in such a way that a text which, for example, is imaged on the opaque pane can be read from a first side of the pane. If this is mapped onto the projection surface when the pane is transparent, it can be designed, for example, in such a way that it can be read from a second side of the pane. For this purpose, the photograph can be rotated, for example, to Example mirror symmetry. This is advantageous because the optical arrangement allows a light image to be displayed on two different projection planes, ie the opaque pane and the projection surface. As a result, two projectors do not have to be used, as is conventional, in order to irradiate two projection planes. Therefore, another projector can be omitted by the invention, whereby costs, effort in the Mon days and space can be saved. The vehicle window can, for example, be made of intelligent glass (also called SmartGlass), the transparency of which can change, for example, when an electrical voltage is applied (electrochromic) or by changing light conditions (photochromic) or different temperatures (thermochromic). In particular, the pane is formed from electrochromic glass.

The control can be connected to the pane in a wireless manner, for example via Bluetooth or some other wireless connection technology, and / or with a cable. The control can also be connected to the projector wirelessly and / or with a cable. It is also possible for the control to be arranged, for example, on the pane or on the projector. However, the control can also be arranged independently of the disc or the projector. If the optical arrangement is arranged on a vehicle, for example, it is also possible for the control to be part of a control device of the vehicle, for example a light control device. It is also possible that the optical arrangement has at least one input device with which the window can be switched via the control and / or the projector can be controlled. The input can be made by a user, for example, via a program, for example a smartphone app or mobile phone app. If the optical arrangement is arranged in a vehicle, it is also possible for an input to be made via car-to-car communication (C2C) and / or car-to-environment (C2X). Furthermore, the controller can be configured to control the projector in such a way that, depending on whether the projection is on the pane and / or on the projection surface, the light image of the projector is rotated and / or mirrored or in an initial state. This means that an orientation of the photo can be adjusted via the control. The initial state of the light image can be, for example, a state in which, if the light image represents a text, the text on the opaque pane can be read by a person if the person is on the same side of the pane on which the projector is arranged is. The controller can control the projector in such a way that the light image is adapted in such a way that a person can read writing on the pane. If the person is on the side of the projector, the light image can be emitted via the projector in the initial state. If the person is on the other side of the pane facing away from the projector, the light image is preferably flipped horizontally, ie on an axis that is perpendicular to a writing direction of the text and / or perpendicular to the text plane in comparison to the initial state mirrored. If the light image is projected onto the projection surface and the person is on the side of the projector, ie if the person is viewing the light image through the pane, the projector preferably projects the light image in the initial state. If the person is on the other side of the pane, that is to say on the side facing away from the projector, and if the light image is displayed on the projection surface, the light image is preferably rotated by 180 degrees with respect to the initial state. The axis of rotation can be perpendicular to an image plane of the light image. It is preferably arranged in or approximately in the middle of the projected light image.

In a further exemplary embodiment, the optical arrangement can have a sensor. This can in particular be configured to determine which side of the pane is at least one person. If the optical arrangement is arranged on a vehicle, for example, the sensor can determine whether a person is in the vehicle or is approaching the vehicle. For example, if there is a person in the vehicle, this information can be passed on to the controller, and the window and the projector can be controlled accordingly, so that the person in the vehicle can send a text through the projector is projected can read. If, for example, a person approaches the vehicle with a key for the vehicle, ie if the person is on the other side of the window outside of the vehicle, this can also be passed on from the sensor to the controller, and the steering can thus - control the projector so that, for example, a welcome message is visible to a person approaching the vehicle. If the person is between the reflection surface and the vehicle, the light image can be emitted in the initial state, since the person can thus read the text that represents the light image. If the person is on the side of the projection surface facing away from the vehicle, that is, if the person is facing the vehicle and the projection surface, the light image is preferably emitted by the projector rotated by 180 ° compared to the initial state, so that the person can read a text that represents the photograph. The message can be displayed on the pane or on the projection surface. Depending on where the message is shown, the photo can be adapted accordingly so that it can be correctly read by the person.

The sensor can, for example, be part of a driver recognition system if the visual arrangement is arranged in a vehicle. It is also possible that the sensor is an infrared or ultrasonic sensor and thus enables occupant detection. This can send a signal to the controller when a person is sitting on a vehicle seat. This is advantageous because components that are already in the vehicle can be used. The sensor or another sensor can also be a parking sensor of the vehicle. This can, for example, send a signal to the controller when a person approaches the vehicle. This is advantageous as no further components are required. must be brought. This means that costs can be saved and assembly costs are lower.

In a further exemplary embodiment, the optical arrangement can have a further sensor, in particular an imaging sensor, such as an indoor and / or outdoor camera. It is thus possible, for example, for a viewer to be able to control the optical arrangement using gestures, for example.

It is also advantageous if the pane has at least two sections. In a first exemplary embodiment, a section can, for example, be a normal disk that cannot be switched, and a further section of the disk can be switchable between opaque and transparent. This is advantageous if, for example, a message and / or a symbol and / or moving images are displayed in only one area of the pane and thus costs can be saved, since the remaining section of the pane cannot be made switchable. Furthermore, it can be advantageous because, in particular when the optical arrangement is arranged in a vehicle, a person in the vehicle can continue to look out of the transparent section of the pane and only a section of the pane on which a light is exposed can be switched to be opaque - image can be displayed. This enables, for example, light images to be displayed on the switchable section of the window while the vehicle is in motion. For example, this can be used to indicate to a driver of the vehicle that another vehicle is in the blind spot if a section of a side ten vehicle window is switchable opaque, and can be irradiated by the projector.

In a further exemplary embodiment of the invention, the pane can be divided into at least two switchable sections or has at least two switchable sections, these sections being switchable independently of one another. That is, a first section can be switched to be opaque, while a second section can be switched to be transparent, and vice versa. It is also possible for both sections to be switched to be transparent or opaque. This is advantageous if, for example, a person is outside a vehicle on which the optical arrangement is provided and a person is inside the vehicle. For example, a light image can be imaged on the projection surface through a section of the pane that is switched to be transparent, which can be on a plane on which the vehicle is arranged, and another light image can be imaged on an opaque switched section of the pane. In other words, a projection on the pane and a projection on the projection surface can take place at the same time. The sections can, for example, be continuous de, in particular horizontal and / or vertical sections of the disk. It is also possible for a section to be at least partially surrounded by a further section. If the switchable pane is switched electrochemically and a switchable section of the pane is completely surrounded by a further section, it is advantageous if contacts through which a voltage can be applied to the section are transparent are. This is possible, for example, with contacts made of dium tin oxide (ITO).

In a further exemplary embodiment, it is also possible for the pane to have at least three sections, one section not being switchable and the at least two further sections being switchable, in particular, independently of one another. The pane can thus be divided into sections depending on the application, so the optical arrangement is suitable for many applications. This can also be net angeord, for example, in a department store, wherein the pane can be a shop window. The pane can for example have at least one switchable section through which, for example, passers-by can be informed, and at least one normal, non-switchable section, so that passers-by can view goods displayed in the shop window through it. Due to the transparent, non-switchable section, a photo can also be displayed on a floor in front of the department store. In one embodiment, the controller can have two

Have control units. A first control unit can be connected to the pane via a cable and / or wirelessly and a second control unit can be connected to the projector via a cable and / or wirelessly. The first control unit can be arranged in the vicinity of or on the window and the second control unit can be arranged in the vicinity of or on the projector.

The control units can establish a connection that can be implemented wirelessly and / or via a cable with one another. the exhibit. Alternatively, these can also be unconnected.

If the control units have no connection to one another, it can be detected, for example, via a camera or another imaging sensor whether the pane is transparent or opaque and this information can be communicated to the second control unit and accordingly it can adapt the light image from the projector . Furthermore, the optical arrangement can have a light sensor. This can preferably be irradiated by the projector. In particular, the light sensor can be connected to the first control unit wirelessly and / or with a cable and thus the first control unit can control the pane as a function of a signal of the projector detected by the light sensor. The projector can emit the signal or irradiate the light sensor, and the first control unit can control the pane in accordance with the signal or the irradiation of the light sensor by the projector. For example, if the projection is to take place on the pane, the projector can irradiate the light sensor and the first control unit can then switch the pane to be opaque. This is advantageous because there is therefore no need to have a connection between the control units. Communication between the two control units can take place via the light sensor.

An application example for the optical arrangement is, in particular when the optical arrangement is arranged in a vehicle, that, for example, in a charging electric vehicle, the battery status is indicated by the optical display. Order in the window, which can be a front or a side window of the vehicle, for example, or can be displayed on the projection surface. The projection surface can be, for example, the floor or a hood of the vehicle.

In particular, the optical arrangement also has at least one brightness sensor. This can be used, for example, to differentiate at which location a projection should take place. For example, it is possible to project onto the projection surface at night, since the light image on the projection surface, in particular outside the vehicle, can be easily reproduced in a dark environment. In daylight, for example, the light image can be reproduced on the pane, since a projection on the projection surface can be difficult to see due to daylight.

The projector can be a laser projector, for example a pico projector, since it has a great depth of field. Furthermore, the projector can be, for example, a mini beamer or a beamer. However, a conventional projector can also be used, especially if it has sufficient sharpness in the projection area in which the light image is to be displayed. Furthermore, the projector preferably has a focus setting so that in particular the projection on the pane and on the projection surface appears sharp. The focus setting can be implemented, for example, using an electromechanical objective and / or using lenses with an adjustable focal length. The focus setting can be controllable via the control. This is advantageous, since no further components are required for the control.

Furthermore, it is possible that an impression can be created that both the projection surface and the pane are projected at the same time. This can be implemented, for example, in that the pane and the projector are switched and / or controlled synchronously with a frequency of at least 50 Hz, preferably at least 60 Hz. In order to avoid noticeable flickering, the frequency of the circuit can be at least 120 Hz, i. H. both for the disc and for the projection surface 60 Hz. The synchronization can take place, for example, via the light sensor, which is described above. The projector can irradiate the light sensor and then the control can switch the pane to be opaque, so that the change in orientation of the light image emitted by the projector is synchronized with the switching of the pane. Accordingly, the screen and the projector can be synchronized via the signal that is output by the projector.

It is also possible that the pane is switched to be semitransparent. In other words, the pane can only be made opaque to a certain percentage, so that the light image can be seen on the projection surface and at the same time on the pane. Thus, a projection on the pane and on the projection surface can take place at the same time. It is advantageous that in this state symmetrical light images or light images that can be recognized by a person in a mirrored or rotated manner are displayed. Furthermore, a vehicle with the optical arrangement is provided. The vehicle can be an aircraft or a water-based vehicle or a land-based vehicle. The land-based vehicle can be a motor vehicle or a rail vehicle or a bicycle. The vehicle is particularly preferably a truck or a passenger car or a motorcycle. The vehicle can also be designed as a non-autonomous or partially autonomous or autonomous vehicle. The projector is preferably arranged in the interior of the vehicle, so that the window and the projection surface can be irradiated through it. The projector is preferably arranged in such a way that it can also irradiate surfaces, such as the road and / or the hood of the vehicle, which can serve as projection surfaces. For this purpose, the projector can be arranged, for example, in a roof lining of the vehicle.

It is also possible that a projector is arranged in the C- and / or D-pillar so that, for example, regardless of which seats are occupied in the vehicle, viewers outside the vehicle can be addressed with messages by opening the rear window and / or the rear windows are designed as switchable panes that can be switched between opaque and transparent and onto which a projection can take place.

Furthermore, the projector in the vehicle can also illuminate areas of the window frame and the door trim. That is, areas next to the window can also serve as a projection surface. Also a pro jection on a pull-out screen, for example a roller blind, is possible.

In a method with the optical arrangement, the control can switch the pane between opaque and transparent depending on the light image of the projector. Furthermore, the controller can control the projector as a function of the switching state of the pane, so that a projection on the opaque pane and / or on the projection surface can be adapted. Disclosed is an optical arrangement with at least one projector and at least one pane, which can be switched at least partially transparent or opaque. The pane can be irradiated by the projector and, if the pane is switched to be opaque, a light image can be displayed on the pane via the projector and / or if the pane is switched to be transparent, a light image can pass through the pane onto a projection surface be mappable. Via a controller, the pane can be switched to be transparent or opaque depending on the light image of the projector, and the light image projected by the projector can be adjusted depending on a switching state of the pane via the controller. Furthermore, a vehicle with the optical arrangement is disclosed and a method with the optical arrangement.

In the following, the invention will be explained in more detail with reference to execution examples. The figures show:

Figures la to lc each a schematic representation of an optical arrangement according to a first embodiment management example, whereby the figures each show a different state,

FIGS. 2a to 2d each show a schematic representation of an optical arrangement according to a second exemplary embodiment, the figures each showing a different state,

FIGS. 3a to 3c each show a schematic representation of an optical arrangement according to a third exemplary embodiment, the figures each showing a different state, and

FIGS. 4a to 4c each show a schematic representation of an optical arrangement according to a fourth exemplary embodiment, the figures each showing a different state. Fig. La shows an optical arrangement 1 with a Projek tor 2 and a disc 4. The projector 2 is arranged in such a way that it can irradiate the disc 4. Furthermore, the optical arrangement 1 has two control units 6, 8, wherein a first control unit 6 can control the pane 4 in such a way that it can be switched between opaque and transparent and the second control unit 8 controls the projector 2 so that a The light image 10 projected by the projector 2 can be aligned and / or an orientation can be adjusted. The light image 10 can be a text, as shown here, or a symbol image. The control unit 6 is connected wirelessly and / or via a cable to the window 4 and the control unit 8 is likewise connected wirelessly and / or with a cable to the projector 2. The control units 6, 8 form a controller 12 and may or may not be connected wirelessly or wired to one another.

The light image 10 is projected by the projector 2 onto the opaque pane 4 which, however, enables the light image 10 to be transmitted, whereby a light image 11 is formed on the pane 4. In other words, the pane 4 is not switched completely opaque and light emitted by the projector can shine through the pane 4, so that an image of the light image is made possible on the pane 4 and at the same time light can radiate through the pane 4. It can be seen that the alignment of the imaged light image 11 is aligned on the opaque pane 4, like the light image 10 that is input from the second control unit 8 to the projector 2. A viewer 13 of the opaque pane 4 cannot read the text projected onto the pane 4 by the projector 2. The viewer 13 is arranged on a disk side of the disk 4 that faces away from the projector 2. A viewer who, however, stands between the pane 4 and the projector 2 could read the light image 11.

The light image 10, which is emitted by the projector 2, also radiates through the semi-opaque pane 4, so that it is also imaged on a projection surface 15 as a light image 16. Since the viewer 13 stands between the projection surface 15 and the pane 4, he can read it.

In FIG. 1b, the optical arrangement 1 is shown, where the pane 4 is switched to opaque via the first control unit 6, so that a transmission of a light image 17 projected by the projector 2 through the pane 4 is not possible. The light image 17, which is projected via the projector 2, is mirrored in comparison to the light image 10 of FIG. 1 a, on an axis which is perpendicular to the text direction of the light image 10. In this example, the light image is reflected on an axis that is perpendicular between the letters I and L. The viewer 13, who stands on the side of the disc 4 facing away from the projector 2, can thus read the text that is projected onto the disc 4.

The optical arrangement is shown in FIG. 1c, the pane 4 being switched to be transparent here via the control unit 6. A light image 18 is projected over the projector 2, which is rotated by 180 ° in comparison to the light image 10 in FIGS. The light image 18 is mirrored in comparison to the light image 10 on an axis which is perpendicular to a writing direction of text which is represented by the light image 18. The light image 18 is projected through the transparent pane 4 onto the projection surface 15. The viewer 13 cannot read the text that is depicted by the photograph 18. A viewer who is facing both the projection surface 15 and the pane 4 could read the light image on the projection surface 15. FIG. 2a shows a further optical arrangement 19 which, like the optical arrangement 1 of FIGS. La to lc, has a switchable pane 20 and a projector 22. A control 23 which controls the projector 22 and / or the pane 20 is connected to the pane 20 and the projector 22 in a wireless manner. In Fig. 2a shows the disc be 20 from one side on which the projector 22 is arranged net is. The pane 20 is switched to opaque via the control 23 in FIG. 2a and a projected light image 24 can be read by a viewer from this side. The light image 24 is emitted in an initial state. In Fig. 2b, the disc 20 is semi-transparent Darge provides. It can be seen that the light image 24 is projected in the initial state, as in FIG. 2a. An observer who is on the same side as the projector 22 can read both the light image 24 shown on the semitransparent pane 20 and a light image 24 on a projection surface 24 which, for reasons of clarity, is not given a reference symbol here can be seen, the photograph shown is 26.

In FIG. 2 c, the optical arrangement 19 is shown from the side facing away from the projector 22. In this example, the projection takes place on the projection surface 27. It can be seen that the light image 28 projected in FIG. 2c is rotated by 180 degrees compared to the light image that is shown in FIG. 2b from the projector 22 is projected. In other words, it is advantageous if a control unit, which is not shown here, controls the projector 22 in such a way that the light image 28 is rotated by 180 degrees compared to the light image in the initial state shown in FIG. 2a, when a viewer looks at the projection surface 26 from a side of the pane 20 that faces away from the projector 22.

In FIG. 2d, the optical arrangement 19 is shown from the same side of the disk 20 as in FIG. 2c. In this case, the pane 20 is switched to opaque via the control 23, and therefore it and the projector 22 are not not to be seen through the pane 20. It can be seen that the light image 30, which a viewer can see on the opaque pane 20, is mirrored by the control 23 in comparison to the light image 24 of FIGS. 2a and 2b, that is to say is flipped horizontally. In other words, the light image 30 is mirrored in comparison to the initial state on an axis which is perpendicular to a writing direction of the text.

In FIG. 3 a, an optical arrangement 32 is shown which has a projector 34 and a switchable pane 36. The projector 34 is wirelessly and / or connected to a control unit 40 via which a light image emitted by the projector 34 can be adapted. The pane 36 is connected wirelessly or by cable to a control unit 42, via which the pane 36 can be switched to be opaque or transparent. The control unit 40 and the control unit 42 are part of a control of the optical arrangement's rule. Furthermore, the optical arrangement 32 has a light sensor 44. This can be irradiated by the projector 34. In Fig. 3a, the optical Anord voltage 32 is switched off. That is, the projector 34 does not project any light image and the pane 36 is switched to be transparent.

In FIG. 3b, the projector 34 projects a light image 45 which is mapped onto a projection surface 46 through the transparent pane 36. The projector 34 does not irradiate the light sensor 44 in this state.

In FIG. 3c, the projector 34 is controlled by the control unit 40 in such a way that it irradiates the light sensor 44 with light, which is wireless or connected to the control unit 42 connected with cable. The light sensor 44 forwards this signal to the control unit 42, which can then switch the pane 36 to opaque so that a light image 47 is imaged on the pane 36. This is advantageous since the control units 40, 42 therefore do not require a direct connection and can communicate using the method described above.

4a shows a switchable disk 48, which is shown from a side facing away from a projector. Therefore the projector is not shown in this illustration. The disc 48 is arranged in a vehicle door 50 of a vehicle 52, which is indicated by a dashed line. A sensor 54 can be arranged on the vehicle door 50, for example, which can be used to determine the side of the window 48 on which an observer is located. In this example, the disc 48 is switched to be opaque and the illustration in FIG. 4a shows that a light image 55 with text is displayed on the opaque disc 48 via the projector, which is not shown.

In Fig. 4b it is shown that the disc 48 is divided into two sections from. A first section 56 is shown transparently in FIG. 4b. The section 56 of the disk 48 can be switchable independently of the further second section 58. The section 58 is shown switched to opaque here, on this a light image 59 is shown, which shows an arrow. In Fig. 4a, both sections 56, 58 are switched to opaque. Furthermore, an image of a light image 61 can take place through the transparent section 56 on a projection surface 60. In FIG. 4c, both sections 56, 58 of the pane 48 are switched to be transparent and only the light image 61 is shown on the projection surface 60.
