Description

[0001] The invention relates to a system and a method for displaying a virtual vehicle interior.

[0002] When conceptualizing and designing new vehicle interiors, it is particularly important to have a spatial model of the vehicle interior available during the design process, as the visual effect of a designed concept on a screen often differs from its actual visual effect.

[0003] A spatial model of the vehicle interior often allows designers to better grasp the sizes, relationships, colors, materials and surfaces of the individual vehicle interior components than on a screen, thus simplifying the development of coherent and visually appealing design concepts.

[0004] In the past, three-dimensional models of vehicle interiors were created using various materials such as plaster, clay, loam, or wood. However, since modeling such prototypes is very costly and time-consuming, the trend has shifted to digitally visualizing designed vehicle interior concepts. Virtual vehicle interiors are not only used by designers during the design phase but are also employed for presentation purposes when internal company decisions need to be made regarding the interior design of a new vehicle.

[0005] To provide a virtual vehicle model, DE 10 2014 009 701 A1 proposes the use of virtual reality glasses. However, the proposed method only allows the vehicle to be displayed from an external perspective and is therefore not helpful for the interior design of vehicles.

[0006] The perspective from which the spatial model of the vehicle interior is presented is important for both the design work and the presentation of a designed interior concept, so that the viewer is given the most realistic impression possible of the vehicle interior.

[0007] German patent application DE 10 2014 009 697 A1 proposes using virtual reality glasses to display a virtual vehicle interior within a vehicle, allowing the user to view the virtual interior from a vehicle seat and to perceive certain interior components, such as the steering wheel, haptically. However, a disadvantage is that the vehicle dictates the position and geometry of the haptically perceptible interior components, meaning that different vehicles are required to realistically reproduce different virtual interior concepts.

[0008] DE 10 2013 021 138 A1 relates to a simulation arrangement for simulating the interior of a vehicle of a predefinable type of motor vehicle.

[0009] DE 101 18 397 A1 discloses a system and method for the subjective assessment of a vehicle design in a virtual environment using virtual reality.

[0010] German patent DE 10 2015 003 884 A1 relates to a vehicle with a system for detecting lane markings, particularly for automated or assisted driving. It describes a method in which lane markings are detected using sensors (e.g., camera, radar, lidar) and their course is analyzed to precisely determine the vehicle's position on the road.

[0011] The invention is based on the objective of providing a way to realistically reproduce a large number of different virtual vehicle interiors using a single system.

[0012] This problem is solved by a system according to claim 1 or a method according to claim 8.

[0013] The system according to the invention comprises one or more vehicle interior components and digital glasses which are configured to optically reproduce a virtual vehicle interior to a user and to take into account the one or more vehicle interior components during the optical reproduction and with an ultrasound source (48) which is configured to generate a haptic perception of the virtual vehicle interior (24) optically reproduced by the digital glasses (22) for the user by means of ultrasound waves (50), wherein the one or more vehicle interior components are arranged on a platform outside a vehicle.

[0014] The system according to the invention has the advantage that the arrangement and orientation of the one or more vehicle interior components are not predetermined by a vehicle. Thus, the system according to the invention can be used for the realistic representation of a multitude of virtual vehicle interiors. The arrangement of the one or more vehicle interior components on an external platform allows for adaptation to different vehicle types, vehicle classes, and / or vehicle models. Through this adaptation, the user of the glasses can haptically perceive the one or more provided vehicle interior components precisely at the position where they expect them to be based on the optically represented virtual vehicle interior.The system can also include a second or additional pair of digital glasses to allow several people to share a virtual vehicle interior.

[0015] At least one vehicle interior component can have an adjustment device by means of which the position of the corresponding vehicle interior component can be changed. Alternatively or additionally, at least one vehicle interior component can have an adjustment device by means of which the orientation of the corresponding vehicle interior component can be changed. For this purpose, the adjustment device can, for example, comprise one or more rails along which the at least one vehicle interior component can be moved. Preferably, the adjustment device is configured to allow the at least one vehicle interior component to be moved along one axis or along two or three axes. Alternatively or additionally, the adjustment device can comprise a joint by means of which the angle of attack or the inclination of the at least one vehicle interior component can be adjusted.Preferably, the adjustment device is configured to rotate at least one vehicle interior component about one axis or about two or three axes. The adjustment device can, for example, be manually adjustable or have electric actuators for setting a position and / or orientation. The electric actuators are preferably configured to be controlled by a control unit.

[0016] The digital glasses can be designed as virtual reality glasses. Preferably, the digital glasses designed as virtual reality glasses are connected to a computing unit, for example, a personal computer or one or more servers, via a signal-conducting connection. This connection can be wired or wireless. The computing unit can be configured to calculate the display to be reproduced by the digital glasses and to provide the digital glasses with a corresponding signal for the optical reproduction of the virtual vehicle interior. The display reproduced by the digital glasses designed as virtual reality glasses preferably also includes a virtual representation of one or more provided vehicle interior components. In an alternative embodiment, the digital glasses are designed as augmented reality glasses.Preferably, the digital glasses designed as augmented reality glasses are configured to optically reproduce a virtual vehicle interior without a signal connection to an external computing unit. However, it is also possible for the digital glasses designed as augmented reality glasses to have a corresponding playback signal from a computing unit available. Preferably, the augmented reality glasses are configured to provide the user with a display that includes both virtual objects and physically existing objects, such as one or more provided vehicle interior components. Regardless of whether the digital glasses are designed as virtual reality glasses or augmented reality glasses, they can include one or more sensors and / or one or more cameras.Preferably, the digital glasses include one or more position sensors, one or more velocity sensors, one or more acceleration sensors, and / or one or more tilt sensors. These sensors allow the movement of the digital glasses, and thus the movement of the user's head, to be monitored, so that when the digital glasses move, the displayed representation of the virtual vehicle interior changes according to the new perspective. Environmental information acquired by the camera can also be taken into account when displaying the virtual vehicle interior. This allows, for example, the user's body parts and their movements to be integrated into the display of the virtual vehicle interior, further enhancing the realism of the representation.

[0017] The one or more vehicle interior components can include one or more vehicle seats. The one or more vehicle seats serve to create a realistic seating sensation for the user of the digital glasses. This is achieved, on the one hand, by specifying a seating position and, on the other hand, by allowing the user to haptically perceive the one or more vehicle seats while viewing the virtual vehicle interior. Preferably, the one or more provided vehicle seats are taken into account in the optical display by the digital glasses through a virtual representation, or the one or more provided vehicle seats are taken into account in the optical display by the digital glasses in such a way that they are realistically perceptible through the digital glasses.

[0018] One or more vehicle interior components can include a steering wheel. The steering wheel is thus haptically perceptible to the user of the digital glasses while viewing the virtual vehicle interior, for example, by touching it, thereby further increasing the realism. Preferably, the steering wheel is represented virtually in the optical display by the digital glasses, or it is incorporated into the optical display by the digital glasses in such a way that it is realistically perceptible through the glasses.

[0019] The one or more vehicle interior components can include one or more foot pedals, for example, two or three. The one or more foot pedals are thus haptically perceptible to the user of the digital glasses while viewing the virtual vehicle interior, for example, by touching them with their foot, thereby further increasing the realism. Preferably, the one or more foot pedals are represented virtually in the optical display by the digital glasses, or they are positioned in such a way that they are realistically perceptible through the digital glasses.

[0020] The system can further include a control unit that is connected to the digital glasses via a signal conductor and is configured to influence the glasses' optical display. For example, different virtual vehicle interiors can be set using the control unit. For instance, the control unit is configured to cause the digital glasses to visually display the virtual interiors of different vehicle types. For the purposes of the invention, the following vehicle types are distinguished, for example: passenger cars, trucks, buses, tractors, vans, as well as various types of ships and aircraft. Alternatively or additionally, the control unit is configured to cause the digital glasses to visually display the virtual interiors of different vehicle classes.For the purposes of the invention, the following vehicle classes are distinguished, for example: sedan, station wagon, convertible, off-road vehicle, sports utility vehicle, sports car, crossover utility vehicle, commercial vehicle, light vehicle, microcar, and small car. Alternatively or additionally, the control unit is configured to cause the digital glasses to visually display the virtual interior of different vehicle models. For the purposes of the invention, a distinction is made, for example, between the various vehicle models of individual vehicle manufacturers.Furthermore, the control unit can instruct the digital glasses to change the optically reproduced perspective of the virtual vehicle interior, to change the optically reproduced geometric structures of the virtual vehicle interior, to change the optically reproduced surface structures of the virtual vehicle interior, and / or to change the optically reproduced colors of the virtual vehicle interior. In this way, a multitude of different virtual vehicle interiors can be displayed via the control unit, thereby significantly simplifying the design of a visually appealing vehicle interior. Moreover, the system according to the invention can be used to present various vehicle interior concepts, since switching between pre-defined displays during the presentation can be carried out using the control unit.

[0021] The control unit can be connected to one or more vehicle interior components via signal transmission and configured to change their position and / or orientation. For example, the digital glasses can first visually reproduce the virtual interior of a sports car. When displaying the sports car's virtual interior, the seat and steering wheel are initially configured in a low seating position and a stretched-out posture. Subsequently, the digital glasses can then visually reproduce the virtual interior of an SUV. When displaying the SUV's virtual interior, the seat and steering wheel are in a second configuration, resulting in a high seating position and an upright posture.In this embodiment, the change from the first configuration to the second configuration can be made using the control unit.

[0022] The control unit can include a display unit for the visual presentation of information and / or one or more input elements for issuing control commands. Preferably, the control unit is designed as a personal computer, tablet, laptop, or smartphone. The display unit can be an LCD, TFT, or LED display, or a touchscreen. The one or more input elements can be pressure-sensitive and / or include one or more buttons or a touchscreen.

[0023] Alternatively, the control unit can also be integrated into the digital glasses. For example, the control unit can include a camera and / or one or more sensors, or be connected to a camera and / or one or more sensors via a signal conductor, so that control commands can be entered via gestures and / or movements by the user of the digital glasses. For example, the digital glasses are configured to visually display a menu structure whose menu items can be selected by a gesture and / or movement of the user.

[0024] The system can also include an ultrasound source designed to create a haptic perception of the virtual vehicle interior, as displayed through the digital glasses, for the user. The ultrasound emitted by the source is reflected off the virtual surfaces of the displayed vehicle interior by the user's limbs, such as their fingers, thus triggering a sensation of touch. The reflection of the ultrasound is therefore perceived by the user as touching an optically displayed, but virtual, surface.

[0025] In the method according to the invention, one or more vehicle interior components are provided on a platform outside a vehicle, along with digital glasses. A virtual vehicle interior is then optically displayed to the user of the digital glasses, taking into account the one or more provided vehicle interior components. Furthermore, the method according to the invention comprises the step of generating haptic perception of the virtual vehicle interior, optically displayed by the digital glasses, for the user by means of ultrasound waves. Preferably, the method includes the step of emitting ultrasound waves such that these are reflected by the user's limbs at the virtual surfaces of the optically displayed vehicle interior, thus triggering a tactile sensation in the user.Through the reflection of ultrasound, the user can perceive a touch on an optically represented, but virtual, surface.

[0026] The method according to the invention has the advantage that the arrangement and orientation of the one or more vehicle interior components are not predetermined by a vehicle. Thus, the method according to the invention can be used for the realistic representation of a large number of virtual vehicle interiors. The arrangement of the one or more vehicle interior components on an external platform allows for adaptation to different vehicle types, vehicle classes, and / or vehicle models.

[0027] The method allows the position and / or orientation of one or more vehicle interior components to be changed. The change in position and / or orientation is preferably achieved by means of one or more adjustment devices. These devices can be manually adjustable and / or include electrically driven actuators. For example, the method includes controlling the electrically driven actuators by means of a control unit. The control unit can be, for example, a personal computer, a tablet, a laptop, or a smartphone. Alternatively or additionally, the method includes replacing one or more vehicle interior components.By changing their position and / or orientation, the provided vehicle interior components can be arranged in space according to the optical representation by the digital glasses, allowing the user to perceive the optically displayed vehicle interior components haptically in the exact areas where they would expect to find them based on the visual representation of the virtual vehicle interior. Replacing one or more vehicle interior components can further enhance the realism. For example, the one or more vehicle interior components might include one or more seats, a steering wheel, and / or one or more pedals. If the size of the provided steering wheel does not correspond to the size of the virtually displayed steering wheel, it would significantly impair the user's perception of reality.The option to replace the provided vehicle steering wheel avoids this impairment.

[0028] The visual representation of the virtual vehicle interior in the digital glasses can be changed by the user's head movement. A user's head movement always results in a change in perspective. This change in perspective can therefore be taken into account by adjusting the visual representation in the digital glasses. The visual representation of the virtual vehicle interior in the digital glasses can also be changed by the user's body movement. Preferably, the method includes detecting the user's body movement using one or more cameras. The realism is significantly increased if the user and their movements are also visually represented by the digital glasses. Thus, for example, the digital glasses can show the user the execution of their own arm movement when gripping the steering wheel.Furthermore, the visual representation of the virtual vehicle interior in the digital glasses can be modified by the user's pupil movement. For this purpose, the method preferably includes the step of detecting the user's pupil movement, in particular by one or more cameras in the digital glasses. In addition, the visual representation of the virtual vehicle interior in the digital glasses can be modified by entering a control command on a control unit. For this purpose, the control unit has, for example, a display unit for the visual representation of information and / or one or more input elements for entering control commands. Using the control unit, for example, it is possible to switch between alternative virtual vehicle interiors for a future vehicle in order to present the different interiors to internal decision-makers.Alternatively or additionally, the visual display of the virtual vehicle interior in the digital glasses can be changed by selecting a control command in a virtual menu displayed to the user. For this purpose, the method preferably includes the step of capturing gestures and / or movements of the user, so that the selection of a control command by the user can be recognized without the need for a physical input device.

[0029] The visual representation of the virtual vehicle interior can be modified by changing the displayed perspective. This is necessary when the user moves their head or eyes. Alternatively or additionally, the displayed geometric structures of the virtual vehicle interior can be changed. Such a change can be used, for example, to virtually represent different equipment options for a vehicle.The virtual vehicle interior can, in its first view, depict a visually striking feature such as a cupholder, a multimedia device (e.g., a radio or video player), a display, an instrument cluster, a navigation system, or a decorative trim strip. In a second view, the corresponding location might be shown only as a panel or a different feature, such as the previously depicted feature in a different size or with a different shape. Furthermore, the surface textures of the virtual vehicle interior can be modified. This allows, for example, the virtual representation of different surface materials and their visual appearance. Alternatively or additionally, the colors of the virtual vehicle interior can be changed.This allows for the selection of harmonious color combinations for the individual components of a vehicle interior. Furthermore, prospective buyers can virtually preview different interior color options to help them decide on a specific interior color scheme.

[0030] The method allows for the visual representation of a virtual vehicle interior of a first vehicle type and a virtual vehicle interior of a second vehicle type. Furthermore, it allows for the visual representation of a virtual vehicle interior of a first vehicle class and a virtual vehicle interior of a second vehicle class. For the purposes of the invention, the following vehicle classes are distinguished, for example: sedan, station wagon, convertible, off-road vehicle, sports utility vehicle, sports car, crossover utility vehicle, commercial vehicle, light vehicle, microcar, and small car. In addition, a virtual vehicle interior of a first vehicle model and a virtual vehicle interior of a second vehicle model can be visually represented. For the purposes of the invention, a distinction is made, for example, between the different vehicle models of individual vehicle manufacturers.The position and / or orientation of one or more vehicle interior components can be adjusted according to a selected vehicle type, vehicle class and / or vehicle model.

[0031] Further preferred embodiments of the invention result from the other features mentioned in the dependent claims.

[0032] Unless otherwise stated in individual cases, the various embodiments of the invention mentioned in this application can be advantageously combined with one another.

[0033] The invention is explained below using exemplary embodiments with reference to the accompanying drawings. These show: Fig. 1 a schematic representation of an embodiment of the system according to the invention for displaying a virtual vehicle interior; and Fig. 2 a block diagram for an embodiment of the inventive method for displaying a virtual vehicle interior.

[0034] According to Fig. 1 The system 10 according to the invention for displaying a virtual vehicle interior 24 comprises a digital glasses 22, a first control unit 38, a second control unit 42, an ultrasound source 48 and several vehicle interior components 12-20, namely here two vehicle seats 12, 14, a vehicle steering wheel 16 and two foot pedals 18, 20. All vehicle interior components 12-20 are arranged on a platform 26 outside a vehicle.

[0035] The digital glasses 22 are designed to optically reproduce a virtual vehicle interior 24 for a user and to take into account the provided vehicle interior components 12-20 during the optical reproduction.

[0036] Vehicle seat 12 has an adjustment device 28 by means of which the position and orientation of vehicle seat 12 can be changed. Vehicle seat 14 has an adjustment device 30 by means of which the position and orientation of vehicle seat 14 can be changed. The adjustment devices 28 and 30 each have three rails, each rail allowing the respective vehicle seat 12 or 14 to be moved along an axis. In addition, the adjustment devices 28 and 30 each have a joint that allows the respective vehicle seat 12 or 14 to be rotated about three different axes.

[0037] The vehicle steering wheel 16 has an adjustment device 32 by means of which the position and orientation of the vehicle steering wheel 16 can be changed. Furthermore, the vehicle steering wheel 16 is replaceable. The foot pedal 18 has an adjustment device 34 by means of which the position and orientation of the foot pedal 18 can be changed. The foot pedal 20 has an adjustment device 36 by means of which the position and orientation of the foot pedal 20 can be changed.

[0038] All adjustment devices 28-36 have an electric actuator by means of which the position and inclination of the corresponding vehicle interior component 12-20 can be controlled via the first control unit 38 and the second control unit 42.

[0039] The digital glasses 22 are designed as augmented reality glasses and are configured to optically reproduce the virtual vehicle interior 24 without a signal-conducting connection to an external computing unit, and with a signal-conducting connection to provide the user with a representation that includes both virtual objects and physically present objects, namely the provided vehicle interior components 12-20. The digital glasses 22, designed as augmented reality glasses, are wirelessly and via a signal conductor connected to the first control unit 38 and the second control unit 42, as well as to the adjustment devices 28-36 of the vehicle interior components 12-20.

[0040] The control units 38 and 42 are configured to influence the optical display of the digital glasses 22. To influence the optical display of the digital glasses 22, the tablet-type control unit 38 has a touchscreen, which serves as a display unit 40 for the optical display of information and as an input element 40 for inputting control commands. The laptop-type control unit 42 has a display unit 44 designed as an LCD display and several input elements 46 designed as buttons.

[0041] The control units 38, 42 are also connected via signal transmission to the adjustment devices 28-36 of the vehicle interior components 12-20 and are designed to change the position and orientation of the vehicle interior components 12-20.

[0042] The ultrasound source 48 is designed to generate haptic perception of the virtual vehicle interior 24, optically reproduced by the digital glasses 22, for the user by means of ultrasound waves 50. The emitted ultrasound waves 50 are reflected by the user's fingers from the surfaces of the virtual vehicle interior, so that the user perceives a touch.

[0043] The Fig. Figure 2 shows an embodiment of the inventive method for displaying a virtual vehicle interior. To provide such a system, the method comprises the following steps: 52) Providing a vehicle seat, a vehicle steering wheel and two foot pedals on a platform outside a vehicle; and 54) Providing digital glasses designed as virtual reality glasses.

[0044] The user of the digital glasses can now be shown a virtual vehicle interior with the following step: 56) Optical reproduction of a virtual vehicle interior of an off-road vehicle, taking into account the vehicle seat, the vehicle steering wheel and the two foot pedals.

[0045] To increase realism, the following step is taken so that the user can perceive the virtual vehicle interior not only visually but also haptically: 58) Creating a haptic perception of the virtual vehicle interior optically reproduced by the digital glasses for the user by means of ultrasound waves.

[0046] However, the position and orientation of the vehicle seat, steering wheel, and two foot pedals do not yet correspond to the model of the virtual vehicle interior. To enable the user of the digital glasses to touch the individual interior components in the positions where they would expect to be able to, based on the displayed virtual interior of the SUV, the following steps are performed by a control unit: 60) Adjusting the position of the vehicle seat and steering wheel according to the selected off-road vehicle; and 62) Adjusting the alignment of the vehicle's steering wheel and the two foot pedals according to the selected off-road vehicle.

[0047] The control unit used is connected to the adjustment devices of the vehicle interior components via a signal conductor, so that the following steps can be carried out after selecting the settings: 64) Changing the position of the vehicle seat and the vehicle steering wheel by means of electrically driven actuators; and 66) Changing the orientation of the vehicle's steering wheel and the two foot pedals by means of electrically driven actuators.

[0048] Since the last provided vehicle steering wheel does not match the steering wheel of the off-road vehicle, namely neither in terms of steering wheel size nor steering wheel geometry, the following step is performed: 68) Replacing the vehicle's steering wheel.

[0049] The following steps will therefore be carried out: 70) Optical reproduction of a virtual vehicle interior of a passenger car; 72) Optical rendering of a virtual vehicle interior of an off-road vehicle; and 74) Optical reproduction of a virtual vehicle interior of a specific off-road vehicle model.

[0050] For a realistic representation, the optical rendering of the virtual vehicle interior in the digital glasses must change when the user moves their head, thus changing their viewing perspective, or when the user changes their gaze direction through pupil movement. The following steps are performed to achieve this: 76) Changing the optical display of the virtual vehicle interior of the digital glasses by a head movement of the user; 78) Changing the optical display of the virtual vehicle interior of the digital glasses by a pupil movement of the user.

[0051] The user's head movements are detected by accelerometers in the digital glasses. The user's pupil movements are detected by cameras in the digital glasses. Furthermore, the user's body movements are detected by cameras in the digital glasses in order to integrate the user's body and movements into the virtual vehicle interior. The following step is performed for this purpose: 80) Changing the optical display of the virtual vehicle interior of the digital glasses by a body movement of the user.

[0052] The virtual vehicle interior can also be modified by entering a command into a control unit. The following steps are performed for this: 82) Changing the optical display of the virtual vehicle interior of the digital glasses by entering a control command on a control unit.

[0053] The control unit is not visible to the user of the digital glasses. However, the user can change the visual representation of the virtual vehicle interior via a virtual menu, for example by performing gestures. The following steps are performed for this: 84) Changing the optical display of the virtual vehicle interior of the digital glasses by selecting a control command in a virtual menu that is optically displayed to the user.

[0054] Changing the visual representation of the virtual vehicle interior includes, for example, the following step to display different equipment options: 86) Changing the optically represented geometric structures of the virtual vehicle interior.

[0055] To display different vehicle interior materials, changing the visual representation of the virtual vehicle interior involves the following step: 88) Changing the optically reproduced surface structures of the virtual vehicle interior.

[0056] To display different available interior colors or color combinations, changing the visual representation of the virtual vehicle interior involves the following step: 90) Changing the visually represented colors of the virtual vehicle interior.

[0057] Since the provided vehicle interior components are located outside a vehicle, the system, after displaying the virtual interior of the SUV and after making the adjustments to the provided vehicle interior components as described above, can be used to display the virtual interior of a luxury sedan. The following steps are performed for this purpose: 92) Optical reproduction of a virtual vehicle interior of a luxury car; 94) Optical reproduction of a virtual vehicle interior of a specific luxury class model.

[0058] The vehicle models described here, in the form of an off-road vehicle and a luxury sedan, are examples; other vehicle models or combinations may also be used.

[0059] The invention thus provides a system and a method which allow a realistic visualization of the interiors of different vehicles and can therefore be used universally by vehicle interior designers in the design of vehicle interior concepts and during design presentations.
