Description

Technical Field

[0001] This disclosure relates, in general, to methods and systems for alleviating motion sickness in occupants of a vehicle. More specifically, this disclosure relates, in general, to methods and systems for simulating fluids based on data indicating the inertial state of a vehicle and for visualizing the simulated fluids inside the vehicle using one or more lighting elements of the vehicle. Background Technology

[0002] Motion sickness occurs when the motion a person sees differs from what their inner ear perceives. Motion sickness can cause dizziness, nausea, and vomiting. For example, motion sickness can occur when occupants are in a vehicle (e.g., a car, train, airplane, ship, etc.). Based on current automotive trends, the incidence of motion sickness in cars is likely to increase. For instance, due to various design considerations, many recently manufactured vehicles have smaller windows. Smaller window sizes also reduce the number of visual motion cues within the vehicle occupant's field of vision, thus increasing the likelihood of motion sickness. Furthermore, because vehicles include additional infotainment features and autonomous driving capabilities, drivers and passengers are likely to spend more time focusing on activities within the vehicle itself. Summary of the Invention

[0035] Overview

[0036] Various aspects of this disclosure relate to methods and systems for alleviating motion sickness in occupants of a vehicle. More specifically, this disclosure as a whole relates to methods and systems for simulating fluids based on data indicating the inertial state of a vehicle and for visualizing the simulated fluids inside the vehicle using one or more illumination elements of the vehicle. Example embodiments of this disclosure relate to simulating and visualizing fluid dynamics inside a vehicle to improve passenger comfort during vehicle movement, thereby preventing or alleviating motion sickness. For example, in some specific embodiments, visual cues consistent with motion perceived by the passenger's inner ear are used to enhance or modify the vehicle interior. That is, the visualization of fluid dynamics closely simulates how humans measure acceleration and angular motion via the movement of fluid in their inner ear. Therefore, fluid visualization is better at capturing the full range of inertial states perceived by occupants of a vehicle.

[0037] For example, in some implementations, unlike artificial horizon simulations, motion sickness mitigation systems utilize the vehicle's own inertial measurements as input to a physics-based model to simulate and visualize fluid dynamics. The simulation results are visualized using lighting elements positioned inside the vehicle. Specific lighting elements can be used to ensure that visual cues are always within the occupants' field of vision, regardless of their activities within the vehicle.

[0038] The example methods and systems disclosed herein for alleviating motion sickness in vehicle occupants do not require occupants to wear virtual reality or augmented reality goggles. Furthermore, the example methods and systems disclosed herein do not require modifying how vehicle occupants perceive the external environment (e.g., by modifying vehicle windows via augmented reality, darkening portions of windows, or adjusting window transparency frequencies). However, in some specific implementations, the visualization of simulated fluids can be achieved via the windows (e.g., via projection-integrated lighting elements).

[0039] This disclosure provides for using sensors available on a vehicle (e.g., a consumer vehicle) to output data indicating the inertial state of the vehicle. For example, the fluid dynamics simulation system may receive data from various sources, including one or more inertial measurement units (IMUs), one or more cameras, one or more velocity sensors, one or more optical detection and ranging (LIDAR) sensors, one or more radio detection and ranging (RADAR) sensors, one or more magnetometers, one or more inclinometers, one or more positioning sensors (e.g., GLONASS sensors, GPS sensors, etc.).

[0040] This disclosure provides a fluid dynamics simulation system that uses a physics-based fluid dynamics model to model the state of a fluid disposed in a container or vessel based on the inertial state of a vehicle. Here, the container or vessel may include a shape corresponding to the shape or configuration of one or more lighting elements disposed inside the vehicle. That is, the fluid container or vessel utilized by the fluid dynamics model can match the configuration of one or more lighting elements in the vehicle for visualizing the simulated fluid. For example, when selecting or identifying ambient lighting (e.g., rectangular or U-shaped) disposed around a display screen for visualizing the simulated fluid, the fluid dynamics model can utilize a container with a similar shape (e.g., a rectangular or U-shaped container) to simulate the fluid state according to the inertial state of the vehicle. The fluid dynamics model can represent the configuration of the lighting elements as a network of nodes or a mesh topology to simulate the motion of the fluid in the container, for example, relative to each node, based on the inertial state of the vehicle. When the model indicates that fluid is flowing into a node, the corresponding lighting element can be activated. When the model indicates that fluid is flowing out of a node, the corresponding lighting element can be deactivated. When the model indicates that the density value at a given node exceeds a first threshold, the intensity of the corresponding lighting element can be increased. When the model indicates that the density value at a given node is less than a second threshold, the intensity of the corresponding lighting element can be reduced. By way of example, nodes (e.g., cells) in the model can have a finite volume, and their density varies based on the amount of fluid contained within the node. For example, a node filled with fluid may have a density value matching the density of the fluid, while a node half-filled with fluid may have a density value between that of fluid and air. For example, a first threshold may correspond to a 3 / 4 full node, and a second threshold may correspond to a 1 / 4 full node. However, other density values ​​may be used, and this disclosure is not limited to this example. In other embodiments, the intensity of the lighting element can scale with the density of its corresponding node. In some embodiments, as another example, the density of the fluid itself can be reflected via the fluid intensity in the model. For example, when the fluid density at a given node exceeds a first threshold, the intensity of the corresponding lighting element can be greater than the intensity of a corresponding lighting element with a lower fluid density.

[0041] In example implementations, the fluid dynamics model can simulate the state of objects suspended in a fluid. For instance, a fluid dynamics simulation system can implement a fluid dynamics model by modeling the state of the fluid, as well as simulating particles (e.g., sand), bubbles, filamentous structures, fibrous structures (e.g., seaweed), or other objects suspended in the fluid. In some specific implementations, the fluid dynamics simulation system can implement a fluid dynamics model by modeling the state of particles (e.g., sand), bubbles, filamentous structures, fibrous structures (e.g., seaweed), or other objects, rather than modeling the state of the fluid.

[0042] In one implementation, the simulated fluid determined by the fluid dynamics simulation system can be visualized inside the vehicle using one or more of a plurality of activatable lighting elements of the vehicle via a fluid visualization system. For example, the fluid visualization system may be configured to utilize (e.g., activate and / or deactivate) one or more lighting elements located inside the vehicle, including dashboard lighting elements, door lighting elements, display screen lighting elements, seat lighting elements, screen bezel lighting elements, window lighting elements, console lighting elements, etc. For example, control circuitry may control ambient lighting on the dashboard, lighting elements located at the bezel of the infotainment display screen, lighting located at displays embedded in various interior components (e.g., on the dashboard, on interior door panels, etc.), lighting located on displays of the infotainment display screen user interface, etc.

[0043] In some implementations, multiple activatable lighting elements of a vehicle used to alleviate motion sickness are restricted or constrained to not obstruct or replace lighting elements that provide a view from inside the vehicle to the outside. In some implementations, multiple activatable lighting elements of a vehicle used to alleviate motion sickness are provided or selected such that, for example, visual cues regarding the inertial state of the vehicle are visible from every viewpoint inside the vehicle, regardless of the activities undertaken by the vehicle occupants.

[0044] Motion mitigation systems can be implemented as part of an active comfort system that allows users to select various settings. For example, various user interfaces can be implemented to allow users to select the location within a vehicle where the motion mitigation system will be applied. Similarly, various user interfaces can be implemented to allow users to select lighting color, the object to be simulated as suspended in a fluid, and the viscosity of the fluid.

[0045] The exemplary aspects of this disclosure provide numerous technical and beneficial effects. As an example, this disclosure promotes improvements in automotive technology by enabling computing systems (such as in-vehicle systems) to prevent or reduce motion sickness experienced by vehicle occupants. This improves vehicle control and reduces user input regarding vehicle comfort features (e.g., temperature, windows, etc.) that occupants might otherwise struggle to access to alleviate motion sickness. Reduced interaction with such features can reduce the use of limited computing resources that would otherwise be required by the vehicle to process user input.

[0046] Mitigating motion sickness experienced by vehicle occupants can improve their driving experience. As another example, mitigating motion sickness by limiting the use of lighting elements to specific areas or locations (rather than utilizing all available lighting elements) by identifying the occupant's position in the vehicle achieves resource savings (e.g., power savings, CPU usage, etc.).

[0047] In some implementations, a division of computational tasks between onboard and remote systems can be provided. For example, in some implementations, simulating fluids (via a fluid dynamics model) based on data indicating the inertial state of the vehicle can be performed by a remote server computing system. Because some computational tasks can be performed remotely from the vehicle on a typically more powerful computing system, the onboard processing requirements can be reduced. Therefore, motion sickness mitigation can be implemented in vehicles lacking the hardware components needed for modeling fluids based on the vehicle's inertial state. This advantageously provides reduced computational resource requirements for motion sickness mitigation and reduced costs associated with vehicles capable of mitigating motion sickness.

[0048] Example System

[0049] The example implementation will now be discussed in more detail with reference to the accompanying drawings.

[0050] Figure 1 A block diagram of an example motion sickness relief system 100 according to an example implementation thereof is illustrated. The motion sickness relief system 100 may be implemented by a computing system (e.g., a vehicle computing system). In some specific implementations, aspects of this disclosure may be performed by a server computing system (e.g., a remote server system including a cloud server system). For example, the server computing system may be implemented to simulate fluid based on data indicating the inertial state of the vehicle and to provide the simulated fluid to the vehicle computing system. Additionally or alternatively, the server computing system may be implemented to output command instructions to the vehicle computing system to visualize the simulated fluid inside the vehicle using one or more of a plurality of activatable lighting elements of the vehicle.

[0051] The motion sickness relief system 100 may include a fluid dynamics simulation system 110 and a fluid visualization system 130.

[0052] The fluid dynamics simulation system 110 can be configured to model or simulate fluid motion (or lack thereof) based on the inertial state of a vehicle using various inputs. For example, data can be received from various sources, including one or more inertial measurement units (IMUs), one or more cameras, one or more velocity sensors, one or more optical detection and ranging (LIDAR) sensors, one or more radio detection and ranging (RADAR) sensors, one or more magnetometers, one or more inclinometers, one or more positioning sensors (e.g., GLONASS sensors, GPS sensors, etc.). Figure 1As illustrated, the fluid dynamics simulation system 110 can receive one or more inputs, including IMU data 121, camera data 122, velocity sensor data 123, LiDAR data 124, RADAR data 125, magnetometer data 126, inclinometer data 127, position data 128, etc.

[0053] The hydrodynamic simulation system 110 can be configured to utilize information or data related to the vehicle's attitude (e.g., roll, pitch, and / or yaw angles) and inertial measurement results (e.g., linear acceleration, angular velocity, etc.) as input. For example, the input can be transmitted to the hydrodynamic simulation system 110 via a vehicle bus. In some embodiments, the input can be transmitted to a server system via a wireless network. For example, in some embodiments, the IMU can be the primary or sole source of input data for the hydrodynamic simulation system 110, and data from other sources (e.g., wheel speed sensors, camera images, LiDAR measurements, RADAR measurements, magnetometer measurements, inclinometer measurements, position measurements, etc.) can enhance the data provided by the IMU. For example, the IMU can provide data related to the vehicle's linear acceleration and angular velocity along six degrees of freedom. In some specific implementations, data relating to the inertial state of a vehicle can be provided from sources other than those provided at the vehicle itself, for example via inertial sensors (e.g., accelerometers and / or gyroscopes) included in a computing device (e.g., a smartphone with an inertial measurement unit and / or other sensors) located within the vehicle. The computing device can be configured in a static or fixed manner to accurately reflect the inertial state of the vehicle.

[0054] The fluid dynamics simulation system 110 can be configured to simulate fluids based on the inertial state of a vehicle using a physics-based fluid dynamics model. In some specific embodiments, the fluid dynamics simulation system 110 can be configured to simulate fluids based on the inertial state of a vehicle and on a known or pre-defined vessel or container having a shape corresponding to the arrangement or configuration of lighting elements disposed in the vehicle. That is, the simulated fluid container or vessel modeled by the fluid dynamics simulation system 110 is configured to match the configuration of lighting elements in the vehicle to be used for visualizing the simulated fluid. For example, when ambient lighting (e.g., rectangular or U-shaped) disposed around a display screen is selected or identified for visualizing the simulated fluid, the fluid dynamics model can utilize a container with a similar shape (e.g., a rectangular or U-shaped container) to simulate the fluid state based on the inertial state of the vehicle.

[0055] For example, as will be discussed later. Figures 4A to 4CAs described in the example, the fluid dynamics simulation system 110 can simulate the state of the fluid by modeling the container as a configuration of nodes corresponding to the configuration of the lighting elements, thereby realizing a fluid dynamics model.

[0056] In some implementations, the fluid dynamics simulation system 110 can implement a fluid dynamics model by modeling the state of the fluid, and by simulating particles (e.g., sand), bubbles, filamentous structures, fibrous structures (e.g., seaweed), or other objects suspended in the fluid. In some implementations, the fluid dynamics simulation system 110 can implement a fluid dynamics model by modeling the state of particles (e.g., sand), bubbles, filamentous structures, fibrous structures (e.g., seaweed), or other objects, rather than modeling the state of the fluid.

[0057] In some implementations, the fluid dynamics simulation system 110 may be configured to adjust the viscosity of the fluid when implementing a fluid dynamics model to modify the fluid's sensitivity to vehicle motion. For example, the fluid dynamics simulation system 110 may be configured to increase the fluid viscosity when implementing a fluid dynamics model in response to vehicle motion exceeding a threshold. For example, the fluid dynamics simulation system 110 may use a viscosity value similar to that of water (e.g., 1.00 centipoise (cP)) as a default value. However, other viscosity values ​​(e.g., 0.6 cP, 1.5 cP, 2.0 cP, 50 cP, 5,000 cP, etc.) may be used. In some implementations, the viscosity value may be changeable according to user preferences, for example, via a user interface.

[0058] The fluid visualization system 130 can be configured to visualize simulated fluids determined by the fluid dynamics simulation system 110 within the vehicle using one or more of a plurality of activatable lighting elements of the vehicle. For example, the fluid visualization system 130 can be configured to utilize (e.g., activate and / or deactivate) one or more lighting elements disposed within the vehicle, including dashboard lighting element 141, door lighting element 142, display lighting element 143, seat lighting element 144, screen bezel lighting element 145, window lighting element 146, console lighting element 147, etc. For example, control circuitry can control ambient lighting on the dashboard, lighting elements disposed at the bezel of the infotainment display screen, lighting disposed at displays embedded in various interior components (e.g., on the dashboard, on interior door panels, etc.), lighting disposed on displays of the infotainment display screen user interface, etc.

[0059] In some implementations, multiple activatable lighting elements of a vehicle used to alleviate motion sickness are restricted or constrained to not obstruct or replace lighting elements that provide a view from inside the vehicle to the outside. In some implementations, multiple activatable lighting elements of a vehicle used to alleviate motion sickness are provided or selected such that, for example, visual cues regarding the inertial state of the vehicle are visible from every viewpoint inside the vehicle, regardless of the activities undertaken by the vehicle occupants.

[0060] In some implementations, multiple activatable lighting elements are provided or selected for vehicles used to alleviate motion sickness, making visual cues regarding the inertial state of the vehicle visible from designated areas of the vehicle. For example, a specific area of ​​the motion sickness relief system 100 to be applied can be specified based on user input (e.g., via a user interface, including voice input, touch input, etc.). For example, a specific area of ​​the motion sickness relief system 100 to be applied can be specified based on the vehicle detecting the position of occupants in the vehicle (e.g., via a seat detection system, including via weight sensors, camera detection, etc.).

[0061] In some implementations, multiple activatable lighting elements are provided or selected for vehicles used to alleviate motion sickness, such that visual cues regarding the inertial state of the vehicle are visible based on the positions of the occupants within the vehicle. For example, the lighting elements to be controlled to implement the motion sickness mitigation system 100 may be specified based on the occupant's position. For example, the occupant's position (e.g., driver's seat, front passenger seat, rear passenger seat, etc.) may be specified based on user input (e.g., via a user interface, including voice input, touch input, etc.). For example, the occupant's position may be specified based on the vehicle detecting the occupant's position within the vehicle (e.g., via a seat detection system, including via weight sensors, camera detection, etc.).

[0062] In some implementations, multiple activatable lighting elements for vehicles used to alleviate motion sickness are provided or selected such that visual cues regarding the inertial state of the vehicle are visible depending on the direction the vehicle occupant is looking. For example, the lighting elements to be controlled to implement the motion sickness relief system 100 can be specified based on the direction the occupant is looking (e.g., for a predetermined duration or longer). For example, the direction the vehicle occupant is looking can be determined based on the vehicle detecting the occupant's viewing direction (e.g., via camera detection, gaze detection, eye tracker, etc.). As an example, if the occupant is facing backwards from the vehicle, the motion sickness relief system 100 can control lighting elements that are within the occupant's line of sight or field of vision, rather than lighting elements behind the occupant or outside the occupant's field of vision. To avoid frequent changes in the lighting elements to be used by the motion sickness relief system 100 due to frequent changes in the occupant's viewing direction, the motion sickness relief system 100 can ensure that the occupant maintains the viewing direction for a minimum duration (e.g., a predetermined duration or longer) before determining whether to change or update the lighting elements to be controlled to achieve the motion sickness relief system 100 based on the occupant's viewing direction.

[0063] The fluid visualization system 130 can be configured to visualize, for example, a simulated fluid determined by a fluid dynamics simulation system 110 inside the vehicle, using one or more of a plurality of activatable lighting elements of the vehicle according to various methods. For example, the lighting intensity can vary based on the density of nodes determined based on the simulated fluid. For example, the color of the lighting elements can change according to the simulated fluid. (See below for reference.) Figures 2A to 2C Discussion example visualization.

[0064] See Figure 2A An exemplary specific implementation of a motion sickness relief system according to an example embodiment of the present disclosure is shown. For example, Figure 2A Arrow 210 illustrates that vehicle 200A is turning right. Figure 2A In the example, arrow 210 is an image annotation and is not actually displayed on the windshield of vehicle 200A. Sensors including an inertial measurement unit can provide data indicative of the inertial state of vehicle 200A to a fluid dynamics simulation system 110, which can model the simulated fluid based on the lighting elements to be activated. For example, the fluid dynamics simulation system 110 can treat each corresponding internal component with lighting elements as a separate container when modeling the fluid, or the fluid dynamics simulation system 110 can combine internal components with lighting elements and treat the combined internal components as a single container when modeling the fluid.

[0065] like Figure 2AAs illustrated in the example, lighting elements that can be activated to achieve various aspects of the motion sickness relief system 100 (e.g., for visualizing simulated fluids) include door lighting element 142, seat lighting elements 144a and 144b, and screen bezel lighting elements 145a and 145b. For example, a specific color (e.g., blue ambient lighting) can be used to activate the lighting elements. For example, when the vehicle 200A turns right, the fluid can be simulated via a fluid dynamics model as experiencing a centrifugal force pulling the fluid to the left. The simulated fluid can be visualized inside the vehicle 200A via the door lighting element 142, seat lighting elements 144a and 144b, and screen bezel lighting elements 145a and 145b, such that the lighting elements act as visual cues consistent with the sensations of the occupants in the vehicle 200A, thereby alleviating their susceptibility to motion sickness.

[0066] See Figures 2B to 2C This illustrates another exemplary specific implementation of a motion sickness relief system according to an example embodiment of the present disclosure. For example, Figure 2B Arrow 220 illustrates vehicle 200B turning right. Figure 2B In the example, arrow 220 is an image annotation and is not actually displayed on the windshield of vehicle 200B. Sensors including an inertial measurement unit can provide data indicative of the inertial state of vehicle 200B to a fluid dynamics simulation system 110, which can model the simulated fluid based on the lighting elements to be activated. For example, the fluid dynamics simulation system 110 can treat each corresponding internal component with lighting elements as a separate container when modeling the fluid, or the fluid dynamics simulation system 110 can combine internal components with lighting elements and treat the combined internal components as a single container when modeling the fluid.

[0067] The fluid dynamics simulation system 110 can model the simulated fluid itself and one or more simulated objects within the fluid. For example, one or more objects may include one or more of the following: (i) particles, (ii) bubbles, (iii) filaments, or (iv) fibrous structures. In some implementations, the fluid dynamics simulation system 110 can model one or more simulated objects within the fluid, rather than the fluid itself.

[0068] exist Figures 2B to 2C In the example, vehicle 200B features fluid simulation and visualization using dashboard lighting elements 141a (e.g., using blue ambient lighting) mounted on (or integrated with) the dashboard. Furthermore, in Figure 2BIn the example, the fluid is simulated as having suspended bubbles 230a (as indicated by the dark areas). When the vehicle turns right, the inertia of bubble 230a makes the bubble appear to move from left to right from the occupant's perspective. For example, as... Figure 2C As shown, with Figure 2B Compared to bubble 230a, bubble 230b is positioned further to the left on the dashboard. The simulated fluid, along with the simulated bubbles, can be visualized inside the vehicle 200A via dashboard lighting element 141a, so that the activation and deactivation of certain lighting elements from dashboard lighting element 141a serves as a visual cue consistent with the sensations of the occupants in the vehicle 200A, thereby alleviating their susceptibility to motion sickness.

[0069] Figure 3 A block diagram illustrating an example vehicle 300 and a motion sickness relief system including a fluid dynamics simulation system 370 and a fluid visualization system 390 according to an example implementation of this document is shown. Figure 3 The motion sickness relief system and vehicle 300 may be represented in other accompanying drawings (e.g., Figure 1 and Figures 2A to 2C The motion sickness relief system described in the diagram is the same system used in vehicles.

[0081] In one embodiment, the vehicle system 350 may include a non-transitory computer-readable medium 354 (also referred to as memory 354). The non-transitory computer-readable medium 354 may be a storage device (also referred to as a data storage device), which may include electronic storage devices, magnetic storage devices, optical storage devices, electromagnetic storage devices, semiconductor storage devices, or any suitable combination thereof.

Figures 6A to 6D Instructions from any of methods 600, 610, 630, and 640.

[0082] In various implementations, the terms "computer-readable instructions" and "computer-executable instructions" are used to describe software instructions or computer code configured to perform various tasks and operations. In various implementations, if the computer-readable instructions or computer-executable instructions form a module, the term "module" broadly refers to a collection of software instructions or code configured to cause the control circuitry 352 to perform one or more functional tasks.

In addition and / or alternatively, positioning system 358 may utilize computer vision techniques (such as lane recognition techniques) to identify which lane and / or road segment the vehicle 300 is located in. In addition to being beneficial to the control and / or navigation of the vehicle 300, the detections from the positioning system 358 can be used as input data (e.g., position data 128) for the hydrodynamic simulation system 370 to determine the inertial state of the vehicle 300.

[0085] The onboard system 350 can communicate with the fluid dynamics simulation system 370, which can be integrated with the vehicle 300 or located remotely from the vehicle 300. For example, the fluid dynamics simulation system 370 may be or include a remote server. The fluid dynamics simulation system 370 may include one or more control circuits 372. In one embodiment, the one or more control circuits 372 may include one or more processors (e.g., microprocessors), one or more processing cores, programmable logic circuits (PLCs) or programmable logic / gate arrays (PLA / PGA), field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), or any other control circuitry. In some specific implementations, the one or more control circuits 372 may be embodied as one or more control circuits 352. That is, the one or more control circuits 352 of the onboard system 350 may perform the operations of the one or more control circuits 372.

[0086] In one embodiment, the fluid dynamics simulation system 370 may include a non-transitory computer-readable medium 374 (also referred to as memory 374). The non-transitory computer-readable medium 374 may be a storage device (also referred to as a data storage device), which may include electronic storage devices, magnetic storage devices, optical storage devices, electromagnetic storage devices, semiconductor storage devices, or any suitable combination thereof. The non-transitory computer-readable medium may be formed, for example, a hard disk drive (HDD), a solid-state drive (SDD) or solid-state integrated memory, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), static random access memory (SRAM), dynamic random access memory (DRAM), portable optical disc read-only memory (CD-ROM), digital versatile optical disc (DVD), and / or memory stick. In some specific embodiments, the non-transitory computer-readable medium 374 may be embodied as a non-transitory computer-readable medium 354. That is, the non-transitory computer-readable medium 354 of the vehicle system 350 may perform the operations of the non-transitory computer-readable medium 374.

[0087] According to various aspects of this disclosure, the fluid dynamics simulation system 370 can implement or otherwise provide services beneficial to motion sickness relief. The fluid dynamics simulation system 370 can communicate with various vehicle systems or sensors, for example, via an onboard system 350, and input data received from these systems or sensors can be used by the fluid dynamics simulation system 370 to determine the inertial state of the vehicle 300. The fluid dynamics simulation system 370 can store input data in a non-transitory computer-readable medium 374 for determining the inertial state of the vehicle 300. In addition to the input data received from the vehicle 300, the fluid dynamics simulation system 370 can also obtain data through communication with remote or third-party systems. For example, the fluid dynamics simulation system 370 can obtain input data related to the inertial state of the vehicle 300 from an external device (e.g., a smartphone).

[0088] The fluid dynamics simulation system 370 may include a vehicle inertial state detector 380, which is configured to receive input data (e.g., one or more of IMU data 121, camera data 122, velocity sensor data 123, LiDAR data 124, RADAR data 125, magnetometer data 126, inclinometer data 127, position data 128, etc.) and is configured to determine the inertial state of the vehicle 300 based on the received input data. For example, the input data may indicate that the vehicle 300 is turning, stopping (decelerating), accelerating, climbing or parking at an upward angle, descending or parking at a downward angle, at a stop, level, etc.

[0089] The fluid dynamics simulation system 370 may include a fluid dynamics model generator 382 configured to simulate fluids based on input data indicating the inertial state of the vehicle 300. The fluid dynamics model generator 382 may be configured to simulate fluids based on the inertial state of the vehicle 300 using a physics-based fluid dynamics model. In some embodiments, the fluid dynamics model generator 382 may be configured to simulate fluids based on the inertial state of the vehicle 300 and using a physics-based fluid dynamics model based on a known or pre-defined vessel or container having a shape corresponding to the arrangement or configuration of one or more lighting elements disposed in the vehicle. That is, the simulated fluid container or vessel modeled by the fluid dynamics model generator 382 is configured to match the lighting elements in the vehicle to be used for visualizing the simulated fluid. For example, non-transitory computer-readable media 374 and / or non-transitory computer-readable media 354 may store the mapping between lighting element configurations and specified containers or vessels in a database or lookup table. For example, a linear arrangement of lighting elements (e.g., along seats, doors, dashboards, etc.) can correspond to a first container used by the fluid dynamics model, which is linear and tubular in form. For example, a box-shaped arrangement of lighting elements (e.g., lighting elements positioned around a bezel surrounding a display screen, lighting elements positioned around interior door handles, etc.) can correspond to a second container used by the fluid dynamics model, which is also box-shaped and tubular in form. For example, in some embodiments, simulated fluid containers or vessels modeled by the fluid dynamics model generator 382 can each correspond to a specific configuration of lighting elements disposed within the vehicle. For example, in some embodiments, simulated fluid containers or vessels modeled by the fluid dynamics model generator 382 can correspond to a combination of configurations of lighting elements disposed within the vehicle. For example, in Figure 2A In this context, the simulated fluid container or vessel modeled by the fluid dynamics model generator 382 may correspond to a combination of seat lighting elements 144a and 144b. For example, in some specific implementations, some simulated fluid containers or vessels modeled by the fluid dynamics model generator 382 may include portions that are not visible or do not correspond to a particular lighting element configuration (e.g., portions not used to visually represent the simulated fluid). For example, in... Figure 2B In this model, the simulated fluid container or vessel modeled by the fluid dynamics model generator 382 may include a ring extending around the vehicle, wherein a portion of the ring corresponds to the dashboard lighting element 141a, and other portions of the ring do not correspond to the dashboard lighting element 141a. That is, the simulated ring extends around the vehicle and partially surrounds the portion corresponding to the dashboard lighting element 141a, wherein only the portion of the ring that coincides with the dashboard lighting element 141a is visualized using the lighting element representing the simulated fluid.

[0090] For example, the lighting element selector 384 can determine the lighting elements to be used for visualizing simulated fluids. In some embodiments, the lighting element selector 384 can be configured to select all lighting elements in the vehicle 300 as activatable for implementing a motion sickness relief system. In some embodiments, the lighting element selector 384 can be configured to select those lighting elements in the vehicle 300 located in a specific area or seat where the occupant is located (e.g., as determined by the vehicle 300 and / or as determined based on input received from the user) as activatable for implementing a motion sickness relief system. In some embodiments, the lighting element selector 384 can be configured to select those lighting elements in the vehicle 300 located in the occupant's field of vision (e.g., as determined by the vehicle 300 and / or as determined based on input received from the user) as activatable for implementing a motion sickness relief system. For example, if the lighting element selector 384 determines that no occupant is located in the rear area or in the rear seats, the lighting element selector 384 can be configured to exclude lighting elements visible from the rear area or in the rear seats as possible activatable lighting elements for implementation with the motion sickness relief system. For example, if the lighting element selector 384 determines that an occupant is located in the front area or in the front seats, the lighting element selector 384 can be configured to include lighting elements visible from the front area or in the front seats as possible activatable lighting elements for implementation of the motion sickness relief system.

[0091] For example, the fluid dynamics model generator 382 can be configured to simulate a fluid and one or more objects disposed in the fluid using a physics-based fluid dynamics model, based on the inertial state of the vehicle 300. In some specific implementations, the fluid dynamics model generator 382 can be configured to simulate one or more objects instead of a fluid using a physics-based fluid dynamics model, based on the inertial state of the vehicle 300. For a given container or vessel, a given fluid viscosity, and a given force (corresponding to the inertial state of the vehicle), the physics-based fluid dynamics model can simulate the fluid, one or more objects, or the fluid and one or more objects suspended in the fluid, based on a known fluid dynamics model (e.g., based on Bernoulli's principle and equations concerning fluid dynamics).

[0092] For example, physics-based fluid dynamics models can simulate fluids using fluid animation techniques. Fluid animation aims to render realistic fluid visualizations from quantitative results of computational fluid dynamics (CFD) simulations. CFD is a diverse and well-established field of research. Many CFD techniques share the same basic processes and rely on computer-aided design (CAD) models to describe the physical boundaries (e.g., containers or vessels) of the fluid under study. Furthermore, partial differential equations (e.g., the Navier-Stokes equations describing fluid motion) can be used to describe the physics or motion of fluids, and numerical methods can be used to solve these partial differential equations. In some specific implementations, a CFD model can be partitioned by discretizing the fluid domain into a set of computational or discrete elements (e.g., nodes) to form a mesh. Several methods can be used to describe how cells interact with each other while obeying the aforementioned partial differential equations. Examples include, but are not limited to, the finite element method, the finite volume method, etc. For example, the finite element analysis method can be implemented to divide a container (e.g., a pipe) into small elements (e.g., nodes), and partial differential equations can be solved for each element. For example, CFD techniques can use numerical solvers to converge to accurate approximations of fluid dynamics. As yet another example, the Euler equations, which describe the motion of a fluid in the absence of viscosity, can be used to model fluid motion. The Euler equations are a simplified version of the Navier-Stokes equations and are based on the assumption that the fluid is inviscid. In contrast, the Navier-Stokes equations consider viscous forces.

[0093] As described in this article, one or more containers or vessels to be used by a physics-based fluid dynamics model can be determined based on the configuration of the lighting elements to be used to visualize the simulated fluid, one or more simulated objects, or the simulated fluid and one or more objects suspended in the fluid.

[0094] For example, objects may include particles (e.g., sand), bubbles, filamentous structures, fibrous structures (e.g., seaweed), or other objects. Specific objects to be utilized by the fluid dynamics model generator 382 can be selected via the fluid object selector 386. The fluid object selector 386 can be configured to automatically select or implement objects to be modeled by the fluid dynamics model generator 382, ​​or objects can be selected via user input.

[0095] As an example, when the lighting element selector 384 identifies that lighting elements from the front region are activatable for the purpose of achieving a motion sickness relief system, while lighting elements from the rear region are excluded as activatable for the purpose of achieving a motion sickness relief system, the fluid dynamics model generator 382 can be configured to utilize a physics-based fluid dynamics model to simulate fluid based on the inertial state of the vehicle 300 and based on containers having shapes corresponding to the configurations of one or more lighting elements disposed in the front region. For example, the front region may include a first lighting element configuration on the dashboard (which is linear), and a second lighting element configuration and a third lighting element configuration (which are box-shaped) surrounding the left and right interior door handles, respectively. Therefore, the fluid dynamics model generator 382 can be configured to model the fluid in the linear and tubular first container (corresponding to the first lighting element configuration) and the fluid in the box-shaped and tubular second container (corresponding to the second and third lighting element configurations).

[0096] For example, the fluid dynamics model generator 382 can be configured to simulate a fluid with a specific viscosity using a physics-based fluid dynamics model based on the inertial state of the vehicle 300. For example, the fluid viscosity selector 388 can be configured to increase the fluid viscosity when implementing the fluid dynamics model in response to the motion of the vehicle 300 exceeding a threshold. Increasing the fluid viscosity can be used to more smoothly visualize the fluid motion via lighting elements disposed within the vehicle 300. For example, the fluid viscosity selector 388 can select a viscosity value similar to that of water (e.g., 1.00 centipoise (cP)) as the default value. However, other viscosity values ​​(e.g., 0.6 cP, 1.5 cP, 2.0 cP, 50 cP, 5,000 cP, etc.) can be selected. In some specific implementations, the viscosity value can be changed according to user preferences, for example, via a user interface.

[0097] The vehicle-mounted system 350 can communicate with the fluid visualization system 390, which can be integrated with or located remotely from the vehicle 300. For example, the fluid visualization system 390 may be or include a remote server. The fluid visualization system 390 may include one or more control circuits 392. In one embodiment, the one or more control circuits 392 may include one or more processors (e.g., microprocessors), one or more processing cores, programmable logic circuits (PLCs) or programmable logic / gate arrays (PLA / PGA), field-programmable gate arrays (FPGAs), application-specific integrated circuits (ASICs), or any other control circuitry. In some specific implementations, the one or more control circuits 392 may be embodied as one or more control circuits 352. That is, the one or more control circuits 352 of the vehicle-mounted system 350 may perform the operations of the one or more control circuits 392.

[0098] In one embodiment, the fluid visualization system 390 may include a non-transitory computer-readable medium 394 (also referred to as memory 394). The non-transitory computer-readable medium 394 may be a storage device (also referred to as a data storage device), which may include electronic storage devices, magnetic storage devices, optical storage devices, electromagnetic storage devices, semiconductor storage devices, or any suitable combination thereof. The non-transitory computer-readable medium may be formed, for example, a hard disk drive (HDD), a solid-state drive (SDD) or solid-state integrated memory, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), static random access memory (SRAM), dynamic random access memory (DRAM), portable optical disc read-only memory (CD-ROM), digital versatile optical disc (DVD), and / or memory stick. In some specific embodiments, the non-transitory computer-readable medium 394 may be embodied as a non-transitory computer-readable medium 354. That is, the non-transitory computer-readable medium 354 of the vehicle system 350 may perform the operations of the non-transitory computer-readable medium 394.

[0099] The fluid visualization system 390 can realize or otherwise provide services beneficial to motion sickness relief according to various aspects of this disclosure. The fluid visualization system 390 can communicate with various vehicle systems or sensors, for example via an onboard system 350, to control one or more lighting elements of the vehicle 300 to visualize simulated fluids (as determined by the fluid dynamics simulation system 370) within the vehicle using one or more of a plurality of activatable lighting elements from the vehicle 300. The fluid visualization system 390 can store various data in a non-transitory computer-readable medium 394 for controlling the state of the lighting elements (e.g., light intensity values, node density thresholds, etc.).

[0100] The fluid visualization system 390 can be configured to visualize simulated fluids determined by the fluid dynamics simulation system 370 within the vehicle 300 using one or more of a plurality of activatable lighting elements from the vehicle 300. For example, the fluid visualization system 390 may include a lighting element controller 396 configured to visualize simulated fluids by activating and / or deactivating one or more lighting elements disposed within the vehicle 300, including dashboard lighting element 141, door lighting element 142, display lighting element 143, seat lighting element 144, screen bezel lighting element 145, window lighting element 146, console lighting element 147, etc.

[0101] For example, the fluid visualization system 390 may include a light intensity selector 398 configured to visualize the simulated fluid by selecting or placing one or more lighting elements within the vehicle 300 based on the simulated fluid. For instance, if the model output indicates that the node density value at a specific node in the container is greater than a first threshold level, the light intensity selector 398 may be configured to increase the intensity of the corresponding lighting element, and if the model output indicates that the node density value at a specific node in the container is less than a second threshold level, the light intensity selector 398 may be configured to decrease the intensity of the corresponding lighting element. For example, if the model output indicates that the node density value at a specific node in the container is between the first and second threshold levels, the light intensity selector 398 may be configured to maintain the intensity of the corresponding lighting element at a default level.

[0102] See Figures 4A to 4C An example visualization of simulated fluid using lighting elements of a vehicle according to an example embodiment of this disclosure is shown. See also Figure 4A For example, the lighting elements are arranged in a rectangular manner on the bezel 412 of the display screen 410, which can be set in a similar manner to... Figure 2A In the vehicle 300 shown, a fluid dynamics model generator 382 can be configured to model the state of the fluid based on the inertial state of the vehicle 300 by simulating a vessel or container having the same or similar shape as the lighting elements arranged rectangularly on the border 412. For example, the vessel or container used to simulate the fluid state based on the inertial state of the vehicle can have the same or similar shape as the lighting elements, but does not need to have the same dimensions (e.g., in length, width, depth, etc.) as the configuration of the lighting elements. The fluid dynamics model generator 382 can be configured to represent the configuration of the lighting elements as a network or mesh topology of nodes. The fluid dynamics model generator 382 can be configured to simulate the motion of the fluid in the container, for example, relative to each node, based on the inertial state of the vehicle.

[0103] In some specific implementations, the corresponding lighting element can be activated when the model output indicates that there is fluid in a specific node of the container, and the corresponding lighting element can be deactivated when the model output indicates that there is air in a specific node (e.g., the fluid has left the node).

[0104] In some specific implementations, when the model output indicates that the node density value at a specific node of the container is greater than a first threshold level, the intensity of the corresponding lighting element can be increased; conversely, when the model output indicates that the node density value at a specific node of the container is less than a second threshold level, the intensity of the corresponding lighting element can be decreased. For example, when the model output indicates that the node density value at a specific node of the container is between the first and second threshold levels, the intensity of the corresponding lighting element can be maintained at the default level.

[0105] See you again Figure 4A For example, for a first inertial state of vehicle 300 (e.g., on a flat road and with a substantially constant speed), various lighting elements 420 can be activated symmetrically (e.g., an equal number of lighting elements 420 are activated on the sides of frame 412), and various lighting elements 422 can be deactivated symmetrically (e.g., an equal number of lighting elements 422 are deactivated on the sides of frame 412). In response to a left turn of vehicle 300 (indicated by arrow 424), vehicle 300 can enter a second inertial state (e.g., centrifugal force acts on vehicle 300). Based on the second inertial state of vehicle 300, fluid dynamics model generator 382 can be configured to model the state of the fluid such that the fluid “sloshes” to one side of a container used in the model, which corresponds to the configuration of the lighting elements. Here, the sloshing effect of the fluid occurs based on the centrifugal force acting on vehicle 300 during a turn, thus the model reflects the inertial state of vehicle 300. The corresponding lighting elements arranged around frame 412 can be activated and deactivated to reflect the simulated fluid. For example, some previously deactivated lighting elements 422' can be activated, and some previously activated lighting elements 420' can be deactivated, so that the activation and deactivation of the lighting elements serve as visual cues consistent with the feelings of the occupants in the vehicle 300, thereby alleviating their susceptibility to motion sickness.

[0106] Similarly, in Figure 4BIn the example, for a first inertial state of the vehicle 300 (e.g., on a flat road and with a substantially constant speed), various lighting elements, including lighting elements 430 and 432, are activated and positioned along the longitudinal direction of the vehicle (e.g., along the floor or along the door). In response to a braking action of the vehicle 300 (indicated by arrow 434), the vehicle 300 can enter a second inertial state (e.g., where a deceleration force acts on the vehicle 300). Based on the second inertial state of the vehicle 300, the fluid dynamics model generator 382 can be configured to model the state of the fluid such that the fluid “sloshes” to one side of a container used in the model, which corresponds to the configuration of the lighting elements. Figure 4B In the example, some previously activated lighting elements 432' can be deactivated, and some lighting elements 430' previously activated at the default lighting intensity level can remain activated but have a higher intensity lighting level based on the increased density of the corresponding nodes in the model, so that the activation and deactivation of lighting elements serve as visual cues consistent with the feelings of the occupants in the vehicle 300, thereby alleviating their susceptibility to motion sickness. Figure 4B The example can also be applied to situations where the state of vehicle 300 changes from being on a flat and level road to being parked downhill or tilted on a hillside.

[0107] Similarly, in Figure 4C In the example, for a first inertial state of vehicle 300 (e.g., on a flat road and with a substantially constant speed), various lighting elements, including lighting elements 440 and 442, are activated and positioned along the lateral direction of the vehicle (e.g., along the dashboard from left to right). In response to a turning maneuver of vehicle 300 (indicated by arrow 434), vehicle 300 can enter a second inertial state (e.g., centrifugal force acts on vehicle 300). Based on the second inertial state of vehicle 300, the fluid dynamics model generator 382 can be configured to model the state of the fluid such that the fluid “sloshes” to one side of a container used in the model, corresponding to the configuration of the lighting elements. Figure 4C In the example, some previously activated lighting elements 440' can be deactivated, and some lighting elements 442' previously activated at the default lighting intensity level can remain activated but have a higher intensity lighting level based on the increased density at the corresponding node in the model, so that the activation and deactivation of lighting elements serve as visual cues consistent with the feelings of the occupants in the vehicle 300, thereby alleviating their susceptibility to motion sickness.

[0108] As mentioned above, various settings regarding motion sickness mitigation systems can be controlled by the occupants of the vehicle. For example, a motion sickness mitigation system can be implemented as part of an active comfort system that can be controlled by the user (e.g., as part of a luxury package). Figures 5A to 5B An example user interface for operating a motion sickness relief system according to an example embodiment of the present disclosure is illustrated.

[0109] Figure 5A An example of a first motion sickness relief user interface 500 is illustrated, comprising multiple user interface elements that can be used to select one or more areas within a vehicle where a motion sickness relief system can be applied. For example, a user can select or identify a specific location within the vehicle to apply motion sickness relief by selecting user interface element 510. The user can then identify or select a specific seat within the vehicle to apply motion sickness relief by selecting one or more of user interface elements 512, 514, 516, and 518 (e.g., via touch input to a touchscreen, cursor selection, voice, input, etc.). Figure 5A This is just an example, and vehicles can include more than Figure 5A Examples include more or fewer seats. For instance, a user can select or identify a specific area within the vehicle to apply motion sickness relief by selecting user interface element 520. The user can then identify or select a specific area within the vehicle (e.g., a front area and / or a rear area) to apply motion sickness relief by selecting one or more of user interface elements 522 and 524. Figure 5A This is just an example, and the means of transportation may include more than Figure 5A Examples of more or fewer regions.

[0110] Figure 5BA second motion sickness relief user interface 500' is illustrated, which includes multiple user interface elements for selecting specific options regarding the execution of a motion sickness relief system. For example, a user can select one or more effects to be applied to motion sickness relief by selecting user interface element 530. For example, a user can select a specific fluid color to be visually represented by lighting elements within the vehicle to apply motion sickness relief by selecting user interface element 532. For example, a submenu may display multiple color options from which the user can select a specific color. For example, a user can select a specific fluid object to be included in the fluid and represented by lighting elements within the vehicle to apply motion sickness relief by selecting user interface element 534. For example, a submenu may display multiple different objects (e.g., particles, bubbles, filamentous structures, fibrous structures, or other objects suspended in the fluid) from which the user can select a specific object. For example, a user can select a specific fluid viscosity of the fluid and represented by lighting elements within the vehicle to apply motion sickness relief by selecting user interface element 536. For example, a submenu may display substances with multiple different viscosity values ​​and / or similar viscosity values ​​from which the user can select a specific viscosity.

[0111] Example methods for alleviating motion sickness

[0112] Figures 6A to 6D Flowcharts illustrating various methods for achieving motion sickness relief according to example embodiments of this disclosure are provided.

[0113] Figure 6A A flowchart illustrating a method 600 for relieving motion sickness is depicted. In one embodiment, method 600 may be... Figure 3 The control circuit 352 of the vehicle-mounted system 350 and / or the control circuit 372 of the fluid dynamics simulation system 370 and / or the control circuit 392 of the fluid visualization system 390 are executed. In another embodiment, method 600 may be performed by... Figure 7 One or more of the control circuits 715, 815, and 915 of the computing system 700 are executed. One or more portions of method 600 may be implemented as an algorithm on the hardware components of the apparatus described herein. For example, the operation of method 600 may be implemented as an operation / instruction executable by computing hardware.

[0114] although Figure 6A For illustrative and discussion purposes, operations performed in a specific order are described; however, the methods of this disclosure are not limited to the specifically illustrated order or arrangement. Various operations of method 600 may be omitted, rearranged, combined, and / or adjusted in various ways without departing from the scope of this disclosure.

[0115] In one implementation, method 600 may begin with or otherwise include operation 602, wherein a computing system (e.g., system 110, 350, 370, and / or 700) receives data indicative of the inertial state of a vehicle (e.g., 200A, 200B, 300) via one or more sensors of the vehicle (e.g., 200A, 200B, 300). For example, the vehicle may be an autonomous vehicle. As discussed above, the data may include one or more of IMU data 121, camera data 122, speed sensor data 123, LiDAR data 124, RADAR data 125, magnetometer data 126, inclinometer data 127, position data 128, etc. For example, data indicating the inertial state may include at least one of the following: (i) vehicle acceleration data, (ii) vehicle angular motion data, (iii) vehicle speed data, (iv) vehicle pitch angle data, (v) vehicle roll angle data, or (vi) vehicle yaw angle data. For example, the control circuitry may receive data indicating the inertial state of the vehicle from at least one of the following: (i) one or more accelerometers, (ii) one or more gyroscopes, (iii) one or more magnetometers, (iv) one or more inclinometers, (v) one or more cameras, (vi) one or more LiDAR sensors, (vii) one or more RADAR sensors, (viii) one or more wheel speed sensors, or (ix) one or more global navigation positioning sensors.

[0116] See still Figure 6A In one embodiment, method 600 may include operation 604, wherein a computational system (e.g., systems 110, 350, 370, and / or 700) simulates a fluid based on data indicating the inertial state of a vehicle (e.g., 200A, 200B, 300). For example, a fluid dynamics simulation system (e.g., systems 110, 350, 370) may be configured to simulate a fluid based on data indicating the inertial state of a vehicle (e.g., 200A, 200B, 300) using a physics-based fluid dynamics model. In one embodiment, the fluid dynamics simulation system (e.g., systems 110, 350, 370) can simulate a fluid by modeling the fluid dynamics associated with a fluid and one or more objects in the fluid based on the inertial state of a vehicle (e.g., 200A, 200B, 300). The object may include one or more of the following: (i) particles, (ii) bubbles, (iii) filaments, or (iv) fibrous structures.

[0117] In some specific implementations, the fluid dynamics simulation system (e.g., systems 110, 350, 370) may be configured to simulate fluids using a physics-based fluid dynamics model based on the inertial state of a vehicle (e.g., 200A, 200B, 300) and based on a known or pre-defined vessel or container having a shape corresponding to the arrangement or configuration of lighting elements disposed in the vehicle (e.g., 200A, 200B, 300). That is, the fluid container or vessel used in the model implemented by the fluid dynamics simulation system (e.g., systems 110, 350, 370) is configured to match the lighting element configuration in the vehicle (e.g., 200A, 200B, 300) for visualizing the simulated fluids, as described herein. For example, non-transitory computer-readable media 374 and / or non-transitory computer-readable media 354 may store mappings between lighting element configurations and designated containers or vessels used by a model implemented by a fluid dynamics simulation system (e.g., systems 110, 350, 370) in a database or lookup table. For example, a linear arrangement of lighting elements (e.g., along seats, doors, dashboards, etc.) may correspond to a first container used by the fluid dynamics model, which is linear and tubular in form. For example, a box-shaped arrangement of lighting elements (e.g., lighting elements positioned around a bezel surrounding a display screen, a configuration of lighting elements around interior door handles, etc.) may correspond to a second container used by the fluid dynamics model, which is also box-shaped and tubular in form. Thus, each of the lighting element configurations (e.g., by position) may be mapped to a separate or common container in the fluid dynamics model, for example, based on the shape of the lighting element configuration.

[0118] In one implementation, when simulating fluid, the computing system can determine, based on data indicating the inertial state of the vehicle, one or more lighting elements from a plurality of activatable lighting elements to be selectively deactivated, activated, or deactivated and activated in order to simulate fluid.

[0119] In one implementation, when simulating fluid, the computing system can determine, from a plurality of activatable lighting elements, one or more lighting elements to be selectively deactivated, activated, or deactivated and activated based on at least one of the occupant's position within the vehicle or based on the occupant's viewing direction.

[0120] In one implementation, the control circuitry may receive data indicating the position of an occupant within the vehicle, and determine one or more lighting elements from a plurality of activatable lighting elements based on the occupant's position for visualizing the simulated fluid, thereby making the visualization of the simulated fluid within the occupant's field of vision.

[0121] In one implementation, the simulated fluid may be based on the fluid's viscosity. For example, method 600 may include operations in which a computational system determines the viscosity of a fluid based on default settings or user settings to model the fluid dynamics associated with the fluid. As described herein, a computational system can determine and visualize simulated fluids based on the fluid's viscosity.

[0122] In one implementation scheme Figure 6A Method 600 may include operation 606, wherein a computing system (e.g., system 110, 350, 370 and / or 700) outputs command instructions to visualize simulated fluid within the interior of a vehicle (e.g., 200A, 200B, 300) using one or more of a plurality of activatable lighting elements from a vehicle (e.g., 200A, 200B, 300). As described herein, the plurality of activatable lighting elements may be located at at least one of: (i) the vehicle's dashboard, (ii) one or more seats of the vehicle, (iii) one or more door panels of the vehicle, (iv) one or more displays of the vehicle, (v) one or more windows of the vehicle, or (vi) one or more consoles of the vehicle. For example, a fluid visualization system (e.g., system 130, 350, 390) may be configured to utilize (e.g., activate and / or deactivate) one or more lighting elements located inside a vehicle (e.g., 200A, 200B, 300), including dashboard lighting element 141, door lighting element 142, display lighting element 143, seat lighting element 144, screen bezel lighting element 145, window lighting element 146, console lighting element 147, etc.

[0123] Fluid visualization systems can output commands to activate, deactivate, or deactivate and activate one or more of a plurality of activatable lighting elements to visually represent fluids inside a vehicle. For example, as described herein, the plurality of activatable lighting elements can be arranged in an array. Commands can be configured to deactivate, activate, or deactivate and activate one or more of the plurality of activatable lighting elements arranged in an array to visualize simulated fluids.

[0124] In one implementation, to simulate a fluid, method 600 may include determining the motion of suspended bubbles or other objects (e.g., particles, filaments, fibrous structures, etc.) in the fluid based on data indicating the inertial state of a vehicle. Command instructions may be configured to cause one or more lighting elements from a plurality of activatable lighting elements to be controlled to represent the motion of suspended bubbles in the fluid based on the inertial state of the vehicle.

[0125] Figure 6BA flowchart illustrating a method 610 for relieving motion sickness is depicted. In one embodiment, method 610 may be provided by... Figure 3 The control circuit 352 of the vehicle-mounted system 350 and / or the control circuit 372 of the fluid dynamics simulation system 370 and / or the control circuit 392 of the fluid visualization system 390 are executed. In another embodiment, method 610 may be performed by... Figure 7 One or more of the control circuits 715, 815, and 915 of the computing system 700 are executed. One or more portions of method 610 may be implemented as an algorithm on the hardware components of the apparatus described herein. For example, the operation of method 610 may be implemented as an operation / instruction executable by computing hardware.

[0126] although Figure 6B For illustrative and discussion purposes, operations performed in a specific order are described; however, the methods of this disclosure are not limited to the specifically illustrated order or arrangement. Various operations of method 610 may be omitted, rearranged, combined, and / or adjusted in various ways without departing from the scope of this disclosure.

[0127] In one implementation, method 610 may begin with or otherwise include operation 612, wherein a computing system (e.g., system 110, 350, 370, and / or 700) receives a first input for executing a motion sickness relief application. For example, the motion sickness relief application may be stored on any of non-transitory computer-readable media 354, 374, 394 and executed in response to the computing system receiving the first input. For example, the first input may be received via voice input, touch input (e.g., through a user interface), etc. The motion sickness relief application may be implemented as part of an active comfort system that allows a user to select various settings. As another example, the motion sickness relief application may be automatically executed by a vehicle (e.g., 200A, 200B, 300) in response to detecting the presence of a specific occupant of the vehicle (e.g., 200A, 200B, 300). For example, occupants may have user preferences or default settings associated with occupants and vehicles (e.g., 200A, 200B, 300) such that when it is determined that an occupant is inside a vehicle (e.g., 200A, 200B, 300), the vehicle (e.g., 200A, 200B, 300) automatically executes a motion sickness relief application.

[0128] See still Figure 6BIn one embodiment, method 610 may include operation 614, wherein a computing system (e.g., system 110, 350, 370 and / or 700) receives a second input in response to executing a motion sickness application, the second input identifying the corresponding location of one or more occupants within a vehicle (e.g., 200A, 200B, 300) or an area within the vehicle (e.g., 200A, 200B, 300). For example, this may be based on user input (e.g., via...) Figure 5A The example user interface (via voice input, touch input, etc.) designates a specific location or area for which the motion sickness relief system is to be applied as a second input. As another example, based on the vehicle's detection of the occupant's position in the vehicle (e.g., via a seat detection system, including detection via weight sensors, cameras, etc.), the specific location or area for which the motion sickness relief system is to be applied can be designated as a second input.

[0129] See still Figure 6B In one embodiment, method 610 may include operation 616, wherein a computing system (e.g., systems 110, 350, 370, and / or 700) determines one or more lighting elements from a plurality of activatable lighting elements for visualizing a simulated fluid based on a second input. For example, when a front region is identified via the second input and a rear region is not identified via the second input, the computing system may include lighting elements from the front region as potential activatable lighting elements for visualizing the simulated fluid. For example, when a front region is identified via the second input and a rear region is not identified via the second input, the computing system may exclude lighting elements from the rear region as potential activatable lighting elements for visualizing the simulated fluid.

[0130] Figure 6C A flowchart illustrating a method 630 for relieving motion sickness is depicted. In one embodiment, method 630 may be provided by... Figure 3 The control circuit 352 of the vehicle-mounted system 350 and / or the control circuit 372 of the fluid dynamics simulation system 370 and / or the control circuit 392 of the fluid visualization system 390 are executed. In another embodiment, method 630 may be performed by... Figure 7 One or more of the control circuits 715, 815, and 915 of the computing system 700 are executed. One or more portions of method 630 may be implemented as an algorithm on the hardware components of the apparatus described herein. For example, the operation of method 630 may be implemented as an operation / instruction executable by computing hardware.

[0131] although Figure 6CFor illustrative and discussion purposes, operations performed in a specific order are described; however, the methods of this disclosure are not limited to the specifically illustrated order or arrangement. Various operations of method 630 may be omitted, rearranged, combined, and / or adjusted in various ways without departing from the scope of this disclosure.

[0132] In one implementation, method 630 may begin with or otherwise include operation 632, wherein a computing system (e.g., systems 110, 350, 370, and / or 700) receives data indicating the location of occupants within a vehicle (e.g., 200A, 200B, 300). For example, the computing system (e.g., systems 110, 350, 370, and / or 700) may receive data indicating a specific location or area, which the motion sickness relief system will then input based on user input (e.g., via...). Figure 5A Example user interfaces (via voice input, touch input, etc.) are applied to that specific location or area. As another example, computing systems (e.g., systems 110, 350, 370, and / or 700) can receive data indicating the specific location or area to which the motion sickness relief system is to be applied, based on sensor data (e.g., the position of the occupants in the vehicle (e.g., 200A, 200B, 300) is detected by a seat detection system (including via weight sensors, via camera detection, etc.).

[0133] See still Figure 6C In one embodiment, method 630 may include operation 634, wherein a computing system (e.g., systems 110, 350, 370, and / or 700) determines one or more lighting elements from a plurality of activatable lighting elements for visualizing a simulated fluid based on the occupant's position, such that the visualization of the simulated fluid is within the occupant's field of vision. For example, when data indicates that one or more occupants are located in the front region and no occupants are located in the rear region, the computing system may include lighting elements from the front region as potential activatable lighting elements for visualizing the simulated fluid. For example, when data indicates that one or more occupants are located in the front region and no occupants are located in the rear region, the computing system may exclude lighting elements from the rear region as potential activatable lighting elements for visualizing the simulated fluid.

[0134] Figure 6D A flowchart illustrating a method 640 for relieving motion sickness is depicted. In one embodiment, method 640 may be provided by... Figure 3 The control circuit 352 of the vehicle-mounted system 350 and / or the control circuit 372 of the fluid dynamics simulation system 370 and / or the control circuit 392 of the fluid visualization system 390 are executed. In another embodiment, method 640 may be performed by... Figure 7One or more of the control circuits 715, 815, and 915 of the computing system 700 are executed. One or more portions of method 640 may be implemented as an algorithm on the hardware components of the apparatus described herein. For example, the operation of method 640 may be implemented as an operation / instruction executable by computing hardware.

[0135] although Figure 6D For illustrative and discussion purposes, operations performed in a specific order are depicted; however, the methods of this disclosure are not limited to the specifically illustrated order or arrangement. Various operations of method 640 may be omitted, rearranged, combined, and / or adjusted in various ways without departing from the scope of this disclosure.

[0136] In one implementation, method 640 may begin with or otherwise include operation 642, wherein a computing system (e.g., system 110, 350, 370, and / or 700) determines, based on data indicating the inertial state of a vehicle (e.g., 200A, 200B, 300), whether the linear velocity and / or angular orientation of the vehicle (e.g., 200A, 200B, 300) changes over time. For example, the computing system (e.g., system 110, 350, 370, and / or 700) may receive data indicating that the vehicle (e.g., 200A, 200B, 300) is turning, based on data indicating the inertial state of the vehicle (e.g., 200A, 200B, 300).

[0137] See still Figure 6D In one embodiment, method 640 may include operation 644, wherein a computing system (e.g., system 110, 350, 370, and / or 700) models the fluid to simulate the fluid based on whether the linear velocity and / or angular orientation of a vehicle (e.g., 200A, 200B, 300) changes over time. For example, when the vehicle turns in a first direction, the computing system (e.g., system 110, 350, 370, and / or 700) may model or simulate the fluid based on how the linear velocity and angular orientation of the vehicle change over time (which is based on how the direction of the vehicle changes over time). For example, when the vehicle turns left, the computing system (e.g., system 110, 350, 370, and / or 700) may model or simulate the fluid based on how the linear velocity and angular orientation of the vehicle change over time due to the turning direction, such that centrifugal force acts on the fluid in the simulation. For example, when the container or vessel used to model the fluid is linear or partially linear, the simulation can indicate that a vehicle's turning maneuver causes the fluid to slosh in the opposite direction of the turn. Figure 4A and Figure 4CThis is an example of how various lighting elements are activated and deactivated to visualize simulated fluids, based on how the linear velocity and angular orientation of a vehicle change over time (and how its direction changes over time) (during a left turn).

[0138] For example, when a vehicle turns in a first direction, the command instructions are configured to deactivate, activate, or deactivate and activate a first subset of multiple activatable lighting elements to visualize the simulated fluid based on how the vehicle's linear velocity and angular orientation change over time due to the vehicle turning in the first direction; and when a vehicle turns in a second direction, the command instructions are configured to deactivate, activate, or deactivate and activate a second subset of multiple activatable lighting elements to visualize the simulated fluid based on how the vehicle's linear velocity and angular orientation change over time due to the vehicle turning in the second direction.

[0139] Example computing system

[0140] Figure 7 A block diagram of an example computing system 700 according to one embodiment of the present disclosure is illustrated. System 700 includes a computing system 705 (e.g., an in-vehicle computing system), a server computing system 805 (e.g., a remote computing system, a cloud computing platform), and a user device 905 communicatively coupled via one or more networks 750.

[0141] The computing system 705 may include one or more computing devices 710 or circuitry. For example, the computing system 705 may include control circuitry 715 and a non-transitory computer-readable medium 720 (also referred to herein as memory). In one embodiment, the control circuitry 715 may include one or more processors (e.g., microprocessors), one or more processing cores, programmable logic circuitry (PLC) or programmable logic / gate array (PLA / PGA), field-programmable gate array (FPGA), application-specific integrated circuit (ASIC), or any other control circuitry. In some specific embodiments, the control circuitry 715 may be part of, or may form part of, a vehicle control unit (also referred to as a vehicle controller), which is embedded in or otherwise disposed within a vehicle (e.g., In a car or van. For example, the vehicle controller may be or may include an infotainment system controller (e.g., an infotainment head unit), a telematics control unit (TCU), an electronic control unit (ECU), a central powertrain controller (CPC), a charging controller, a central external and internal controller (CEIC), a zone controller, or any other controller. In one embodiment, the control circuitry 715 may be programmed by one or more computer-readable or computer-executable instructions stored on a non-transitory computer-readable medium 720.

[0142] In one embodiment, the non-transitory computer-readable medium 720 may be a storage device (also referred to as a data storage device), which may include electronic storage devices, magnetic storage devices, optical storage devices, electromagnetic storage devices, semiconductor storage devices, or any suitable combination thereof. The non-transitory computer-readable medium 720 may be formed, for example, a hard disk drive (HDD), a solid-state drive (SDD) or solid-state integrated memory, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM or flash memory), static random access memory (SRAM), dynamic random access memory (DRAM), portable optical disc read-only memory (CD-ROM), digital versatile optical disc (DVD), and / or memory stick.

[0143] Non-transitory computer-readable medium 720 may store information accessible by control circuitry 715. For example, non-transitory computer-readable medium 720 (e.g., storage device) may store data 725 that can be acquired, received, accessed, written, manipulated, created, and / or stored. Data 725 may include any of the data or information described herein. In some embodiments, computing system 705 may acquire data from one or more memories located remotely from computing system 705.

[0144] The non-transitory computer-readable medium 720 may also store computer-readable instructions 730 executable by the control circuitry 715. The instructions 730 may be software written in any suitable programming language or may be implemented in hardware. Instructions may include computer-readable instructions, computer-executable instructions, etc. As described herein, in various embodiments, the terms "computer-readable instructions" and "computer-executable instructions" are used to describe software instructions or computer code configured to perform various tasks and operations. In various embodiments, if the computer-readable instructions or computer-executable instructions form a module, the term "module" broadly refers to a collection of software instructions or code configured to cause the control circuitry 715 to perform one or more functional tasks.
