Description

Technical Field

[0001] The invention relates to an information system for a motor vehicle. The invention also relates to a motor vehicle having an information system of the generic type and to a method for operating an information system of the generic type for a motor vehicle. Background Art

[0002] An information system for a motor vehicle is known, which has an image generation device for generating a holographic 3D image. Such an image generation device has, for example, a holographic 3D display, which is designed to present holographic 3D objects and UI elements (“user interface elements”) at almost any distance in front of or behind the 3D display. In the context of the present invention, a holographic 3D object is referred to hereinafter as a “3D object” for short, and a holographic 3D image is referred to as a “3D image” for short. In the context of the present invention, a 3D image is understood to be an arrangement of one or more 3D objects.

[0003] Such 3D displays can offer the occupants of a motor vehicle, such as the driver or his co-driver (Beifahrer, sometimes called a co-passenger), a significantly more complex experience than conventional 2D displays used to date. The hand gestures of the occupants can be detected via a detection device, so that the 3D images generated by the 3D display can be manipulated in a targeted manner via predefined hand gestures. In order to ensure reliable detection of hand gestures, such information systems have one or more so-called "interaction zones", within which hand gestures must be performed in order for control commands to be transmitted to the information system. In order to reduce the risk of detecting accidentally generated hand gestures (for example, hand gestures made by an occupant during a conversation), it has proven useful to limit the input possibilities of hand gestures to the interaction zone. Hand gestures performed outside the interaction zone are therefore usually ignored by conventional information systems.

[0004] With the aid of a 3D display, 3D objects can sometimes also be generated in the interaction zone in order to improve direct interaction with the 3D object. In the context of the invention, direct interaction with a 3D object is understood to mean, for example, optically touching the 3D object or immersing in the 3D object. In this case, it can be provided, for example, that the interaction zone is coupled to the 3D object so that a manual displacement of the 3D object in space results or can result in the interaction zone being moved.

[0005] Alternatively, the 3D object can also be generated in an area separated from the interaction zone, for example, outside the reach of the occupants of the motor vehicle. In this case, interaction with the 3D object can only be achieved indirectly (for example, using a virtual hand, a pointer, etc.). Gestures (Geste, sometimes called gestures) (such as a wiping gesture) can also be predefined, which do not require direct interaction with the 3D object or the 3D image and can therefore be performed in the interaction zone separated from the 3D object even when the 3D object is within the reach of the occupants.

[0006] From document KR 1020150072206A, an information system with a detection system for gestures for interacting with 3D objects is known. The interaction zone can be automatically adapted to the driver's seat position, height or age in order to avoid the interaction zone being out of the driver's reach. In addition, the manual arrangement of the interaction zone is described. Document US2021 / 0023946A1 discloses an information system for an autonomously operated motor vehicle, in which a plurality of occupants can be provided with a separately adapted environment with 3D images and interaction zones.

[0007] Known information systems have the disadvantage that 3D objects or 3D images are displayed even when the operator of the information system has his hands outside the interaction zone. This can unnecessarily distract or even annoy the driver of the motor vehicle, especially when the 3D object is designed as an operating element. Furthermore, it is currently not possible to quickly change the position of the interaction zone, making it difficult for the driver to interact with the information system in certain driving situations. Summary of the invention

[0008] The object of the present invention is therefore to eliminate or at least partially eliminate the above-mentioned disadvantages in an information system for a motor vehicle. In particular, the object of the present invention is to create an information system for a motor vehicle, a motor vehicle and a method for operating an information system for a motor vehicle which in a simple and cost-effective manner avoid unnecessary distraction of the driver by generating 3D objects and / or provide improved operability, in particular in special driving situations.

[0009] The above-mentioned object is achieved by the patent claims. Accordingly, the object is achieved by an information system for a motor vehicle with the features of the independent claim 1, by a motor vehicle with the features of the parallel claim 9, and by a method for operating an information system for a motor vehicle with the features of the parallel claim 10. Further features and details of the invention are derived from the dependent claims, the description and the drawings. Here, the features and details described with respect to the information system according to the invention naturally also apply with respect to the motor vehicle according to the invention and the method according to the invention, and vice versa, respectively, so that reference is always made to one another or can always be made to one another with respect to the disclosure of the individual inventive aspects.

[0010] According to a first aspect of the invention, the object is achieved by an information system for a motor vehicle. The information system has an image generation device for generating a holographic 3D image, a detection device for detecting movements of a hand of an occupant of the motor vehicle in an interaction zone, and a control device for controlling the image generation device. According to the invention, the detection device is configured to detect movements of the hand outside the interaction zone, wherein the control device is configured to control the image generation device depending on the movements of the hand detected outside the interaction zone, wherein the control device is configured to process movements of the hand outside the interaction zone and movements of the hand inside the interaction zone differently.

[0011] In the context of the present invention, an information system is understood to be a device designed to present information. The information may include, for example, operating data of the motor vehicle (such as speed, rotational speed, tank fill level (Tankfüllstand, sometimes referred to as tank fill level), battery state of charge (SOC), coolant temperature, driving mode, etc.), assistance system data (such as brake assistance, lane assistance, parking assistance, etc.), entertainment data (such as the frequency or name of a selected or selectable radio station, the name of a podcast, etc.). Furthermore, the information may include, for example, input options for the user (UI), such as switches, buttons, controllers, etc.

[0012] The image generating device is configured to generate a holographic 3D object. Preferably, the image generating device is configured to generate a 3D image with one or more 3D objects. For this purpose, the image generating device preferably has a 3D display, a 3D projector, etc. The image generating device with a 3D display is preferably configured to present the 3D object to the viewer before and also after the 3D display. Thus, the 3D object can be presented, for example, between the occupant of the motor vehicle and the 3D display or in such a way that the 3D display is arranged between the occupant and the 3D object. The image generating device with a 3D projector preferably has a 3D projection surface for imaging the 3D object, which can be illuminated by the 3D projector. The image generating device is preferably configured to generate 3D objects (such as operating elements) in the interaction zone and 3D objects (such as information elements) outside the interaction zone.

[0013] The detection device is configured to detect movements of the occupant's hand in the interaction zone and, according to the invention, also outside the interaction zone. For this purpose, the detection device preferably has a depth camera or the like. In the scope of the present invention, the movement of the hand is understood to mean, for example, the arrangement of the hand in a certain situation, the shape of the hand, the posture of the hand, the trajectory of the hand, etc. According to the present invention, the movements can also be distinguished by the timing of the movements performed and can therefore be perceived as different movements. The different timings relate, for example, to the speed and speed changes when performing the movements, the time sequence of different movements, etc. The movement of the hand has the technical function of transmitting the occupant's user input (such as control commands, display commands, etc.) to the information system. In addition, the detection device is configured to transmit the detected movements of the hand to the control device.

[0014] The control device is configured to control the image generating device. Preferably, the control device is configured to control the image generating device depending on the hand movement performed in the interaction zone. Thus, for example, the pressing of a button configured as a holographic 3D object performed by the hand in the interaction zone can be presented by a corresponding joint movement of the button. Alternatively or additionally, further optical changes in the presentation of the 3D image or individual 3D objects, such as color changes, size changes, shape changes, additional 3D objects, alternative 3D objects, fewer 3D objects, etc., can preferably be achieved in response to the hand movement. Preferably, the control device has a recognition device for recognizing the eyes of the occupants of the motor vehicle, wherein the control device is configured to control the image generating device depending on the position of the recognized eyes. In this way, the 3D object can be optimally matched to the occupant's viewing angle, so that only a small number of perspectives are required to generate the 3D object, and the computing effort is significantly reduced for this purpose.

[0015] The control device is configured to process differently the hand movements performed outside the interaction zone and the hand movements performed in the interaction zone. Preferably, the control device is configured so that the hand movements performed in the interaction zone are processed mainly or at least partially differently from the hand movements performed outside the interaction zone, and thus can sometimes have different effects on the information system, in particular the presentation of a 3D object or a 3D image. It is preferred according to the invention that the number of hand movements that can be identified as user inputs is greater in the interaction zone than outside the interaction zone. This can mean, for example, that a first movement can be identified as a first control command in the interaction zone and can be ignored outside the interaction zone. A second movement can, for example, be identified as a second control command in the interaction zone and can be identified as a different third control command outside the interaction zone. It can also be provided according to the invention that the hand movements performed outside the interaction zone can be evaluated less as having differences than the hand movements performed in the interaction zone, so that a plurality of different movements performed outside the interaction zone can be identified as the same user input, while the same hand movement in the interaction zone can be identified as different user inputs.

[0016] Compared to conventional information systems, the information system according to the invention has the advantage that the action area for operating the information system can be better personalized for the operator using simple means and in a cost-effective manner. By detecting hand movements in the interaction area in a targeted manner and processing them differently from hand movements outside the interaction area, additional possibilities for the operability of the information system are provided to the operator, so that significantly faster inputs can be achieved, since active movements of the hand into the interaction area can be avoided.

[0017] According to a preferred improvement of the present invention, it can be provided in the information system that the control device is configured to cause the image generation device to generate a 3D object when the hand is less than a predefined minimum distance from the interaction zone. Preferably, the control device is additionally configured to cause the image generation device to hide (Ausblenden, sometimes referred to as fading) the 3D object when the hand is more than a predefined maximum distance from the interaction zone, wherein the maximum distance is greater than or equal to the minimum distance. According to the present invention, a maximum distance greater than the minimum distance is preferred based on hysteresis in order to avoid flickering when generating the 3D object. This can result in that when the hand is located near the interaction zone, at least a display, a switching object, etc., which are configured as 3D objects, can be displayed. Alternatively or additionally, according to the present invention, it can also be provided that the control device is configured to cause the image generation device to hide the 3D object when the hand reaches the interaction zone. In this context, it can be provided, for example, that the 3D object that is displayed (eingeblendet, sometimes referred to as fading) is only used to mark the interaction zone, such as a direction arrow, a frame of the interaction zone, etc. Instead of hiding, a change in position, size, color, shape, etc. of the 3D object can also be provided. This has the advantage that the guidance of the occupants to the interaction zone can be improved using simple means and in a cost-effective manner. By targeted hiding, redundant information can be better concealed, so that, for example, the driver of the motor vehicle is less distracted from driving the motor vehicle by redundant 3D objects.

[0018] According to the invention, it is preferred that the control device is configured to control the image generating device in such a way that the brightness and / or intensity and / or size of the 3D object generated by the image generating device increases as the distance of the hand from the interaction zone decreases. It is preferred that the change of the 3D object is performed steplessly. The change of the 3D object can be shown as, for example, proportional, disproportionately high (überproportional, sometimes referred to as overproportional) or disproportionately low (unterproportional, sometimes referred to as underproportional) relative to the movement of the hand. In this way, the following effect can be generated, that is, when the hand is at a relatively large distance from the interaction zone, the 3D object is presented as, for example, relatively small and / or dim and / or highly transparent, and when the hand is at a relatively small distance from the interaction zone, the 3D object is presented as larger and / or brighter and / or less transparent. In other words, the recognizability of the 3D object for the user increases when approaching the interaction zone and decreases when moving away from the interaction zone. This has the advantage that the distraction caused by the driver during driving by the 3D object is reduced by simple means and in a cost-effective manner, wherein it is further ensured that the interaction zone and the 3D object are easy to find.

[0019] Further preferably, the control device is configured to control the image generation device to optically mark one or more interaction zones when the hand has a predefined minimum distance from the interaction zone. Here, it is preferred that a predefined minimum distance to the predefined interaction zone is defined, wherein the predefined interaction zone preferably has a greater distance to the steering wheel of the motor vehicle than other interaction zones of the information system. The predefined interaction zone is preferably arranged in the area of ​​the instrument panel, in particular in the central area between the driver and the co-driver. The predefined minimum distance is preferably specified in such a way that the minimum distance is not or cannot be lowered by operating the steering wheel and / or the gear lever, so that undesired optical marking of the interaction zone does not occur. The optical marking of the interaction zone can be configured, for example, to generate a frame, a luminous surface, an arrow, a 3D object, etc. This has the advantage that the feasibility of interaction with the information system according to the occupant's command can be shown to the occupant using simple means and in a cost-effective manner. Therefore, the driver's distraction caused by the 3D object during driving is reduced, and it is further ensured that the interaction zone and the 3D object are easily found. In addition, easier and faster operability of the information system is provided thereby.

[0020] In a particularly preferred design of the present invention, it can be arranged in the information system that the control device is configured to prompt the image generation device to optically mark one or more interactive areas and / or generate 3D objects in response to a predefined gesture of the hand made outside the interactive area. The predefined gesture is preferably determined in such a way that it is significantly different from the usual movement of the hand when driving a motor vehicle in order to reduce the risk of accidental manipulation of the information system. Accordingly, the predefined gesture is preferably an unnatural movement of the hand. Possible gestures for this purpose are, for example, crossing two fingers, turning a clenched fist back and forth, extending one or more fingers, forming a special shape of the hand, etc., especially in consideration of one or more predefined directions. Therefore, even when the hand is away from the interactive area, the display and disappearance of the 3D object can be prompted by the occupant in a targeted manner. This has the advantage that the distraction caused by the 3D object during driving is reduced by simple means and in a cost-effective manner, and further ensures that the interactive area and the 3D object are easily found. In addition, easier and faster operability of the information system is provided thereby.

[0021] Preferably, the control device is configured to cause the image generation device to optically mark the interactive zone when a predefined hand gesture is pointed in the direction of the interactive zone. The predefined gesture can, for example, include extending one or more fingers in the direction of the interactive zone. Thus, by pointing at the interactive zone, the interactive zone can be optically highlighted. The optical marking of the interactive zone can, for example, be configured to generate a frame, a luminous surface, an arrow, a 3D object, etc. This has the advantage that the driver's distraction caused by the 3D object during driving is reduced by simple means and in a cost-effective manner, and further ensures that the interactive zone and the 3D object are easy to find. In addition, an easier and faster operability of the information system is provided thereby.

[0022] According to a preferred embodiment of the present invention, the control device is configured to move the interaction zone in response to a predefined gesture of the hand made outside the interaction zone. In the context of the present invention, movement is understood to be, for example, moving the interaction zone toward or away from the hand. Preferably, the control device is configured to move the interaction zone toward the hand for a predefined first gesture made outside the interaction zone. Further preferably, the control device is configured to move the interaction zone away from the hand for a predefined second gesture made outside the interaction zone. Preferably, the control device is configured in such a way that a movement of the interaction zone extending transversely thereto, such as a lateral or vertical movement transverse to the driving direction, can also be caused by such a gesture. Thus, for example, the following becomes simple, that is, the driver can move the interaction zone into his field of vision while his line of sight is constrained in one direction (for example, toward one side of the vehicle) so that further interaction with the information system can be better performed without changing his line of sight or at least not significantly changing his line of sight. This has the advantage that a simpler and faster operability of the information system is provided by simple means and in a cost-effective manner.

[0023] Particularly preferably, the detection device is configured to detect the motion space of the occupant of the motor vehicle for hand gestures, wherein the control device is configured to arrange the interaction area in the detected motion space. The parameters of the occupant (such as upper body height, upper body position, arm length, etc.) can be acquired (erfassbar, sometimes referred to as recordable) via the depth camera of the detection system and can be transmitted to the control device. The control device is configured to determine the motion space from this. The motion space describes the following space, that is, in which the occupant (for example, the driver of the motor vehicle) can move his hand well in the current seat position to transmit the gesture, in particular without having to change his seat position for this purpose. According to the present invention, the detection of the motion space can also take into account ergonomic aspects. This has the following advantages, that is, using simple means and in a cost-effective manner to provide a simpler and more comfortable operability of the information system.

[0024] According to a second aspect of the invention, the object is achieved by a motor vehicle. According to the invention, the motor vehicle has an information system according to the invention. The image generating device is preferably arranged on the dashboard in the interior of the motor vehicle, preferably between the windshield, the driver's seat and the front passenger seat of the motor vehicle. The detection device is preferably arranged in the interior in the region of the image generating device. Preferably, the detection device has a plurality of detection sensors, such as depth cameras, which are arranged at different locations in the interior of the motor vehicle.

[0025] All the advantages already described for the information system according to the first aspect of the invention are obtained in the motor vehicle according to the invention. As a result, the motor vehicle according to the invention has the advantage over conventional motor vehicles that the action area for operating the information system can be better personalized for the operator using simple means and in a cost-effective manner. By the targeted detection and different processing of hand movements performed within the interaction area relative to hand movements performed outside the interaction area, additional possibilities for the operability of the information system are provided to the operator, so that significantly faster inputs can be achieved, since active movements of the hand into the interaction area can be avoided.

[0026] According to a third aspect of the invention, this object is achieved by a method for operating an information system for a motor vehicle. The method comprises:

[0027] - providing an information system according to the invention,

[0028] - detecting the condition and / or movement of the hand outside the interaction zone by means of a detection device,

[0029] - comparing, by the control device, the detected condition and / or movement of the hand with predefined conditions and / or movements of the hand, and

[0030] The image generating device is controlled by the control device in order to generate a 3D object if the detected position and / or movement of the hand corresponds to a predefined position and / or movement of the hand or is within a predefined tolerance.

[0031] The information system is preferably provided in a manner integrated in a motor vehicle. The hand of an occupant (preferably the driver) of the motor vehicle is detected by a detection device. The action of the occupant's hand made outside the interactive zone, that is, the condition and / or movement of the hand, is detected here. The detected action is compared with a predefined action (that is, the condition and / or movement of the hand predefined as a command gesture) by a control device. According to the present invention, the action predefined outside the interactive zone is at least partially different from the action predefined in the interactive zone. This results in that a specific action performed in the interactive zone can be identified as a control command, while the same action performed outside the interactive zone may not be identified as a control command. In this way, the undesirable transmission of commands is avoided. Nevertheless, at least one action is defined, which is regarded as a control command when performed outside the interactive zone. If the action is detected and it is confirmed during the comparison that the action corresponds to the predefined action, this is identified by the control device as a targeted and intentional interaction of the occupant with the information system, and the image generation device is manipulated to generate a 3D object, preferably a 3D object corresponding to the intentional interaction.

[0032] The method according to the invention yields all the advantages already described for the information system according to the first aspect of the invention and for the motor vehicle according to the second aspect of the invention. The method according to the invention therefore has the advantage over conventional methods that the action area for operating the information system can be better personalized for the operator using simple means and in a cost-effective manner. By detecting hand movements in the interaction area in a targeted manner and processing them differently from hand movements outside the interaction area, additional possibilities for the operability of the information system are provided to the operator, so that significantly faster inputs can be achieved, since active movements of the hand into the interaction area can be avoided.
