Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a motion sickness protection device, a motion sickness protection method, and a vehicle. Background Technology

[0002] The low-frequency characteristics of regenerative braking in electric vehicles can easily trigger vestibular-visual sensory conflict in passengers, leading to motion sickness. However, infants and pets lack the ability to express themselves and make their motion sickness difficult to detect and intervene in a timely manner. Current anti-motion sickness technologies primarily rely on subjective feedback or employ invasive sensors, resulting in delayed intervention and poor comfort, failing to meet user needs. Summary of the Invention

[0003] This application provides a motion sickness protection device, a motion sickness protection method, and a vehicle.

[0004] This application provides a motion sickness protection device, which includes a seat module, a controller, and a motion sickness protection module. The seat module includes a detachable inner cabin and a seat base, wherein the detachable inner cabin includes a first inner cabin adapted to a first type and a second inner cabin adapted to a second type, and the first inner cabin or the second inner cabin is detachably installed on the seat base; The controller is configured to: Based on the behavioral characteristic data of the current target object, the type of the current target object on the seat module is identified, wherein the type of the current target object includes the first type and the second type; Based on the type, motion sickness identification processing is performed on the behavioral feature data to determine whether the current target object is experiencing motion sickness. If the current target object is experiencing motion sickness, a motion sickness protection command corresponding to the current target object is generated to control the motion sickness protection module to execute the motion sickness protection command and provide motion sickness protection for the current target object.

[0005] Thus, based on the detachable interior cabin, a first interior cabin adaptable to the first type and a second interior cabin adaptable to the second type can be quickly adapted according to actual needs, meeting the travel needs of different types of target objects. Simultaneously, by identifying the behavioral characteristic data of the current target object to determine its type, and performing motion sickness recognition processing on the behavioral characteristic data according to the type, differentiated identification and protection can be achieved based on the target object type, improving the accuracy of motion sickness judgment. This allows for early intervention of motion sickness precursors, reducing the probability of motion sickness for the current target object, improving the motion sickness protection effect and the travel experience of the current target object. Compared to invasive physiological monitoring methods for preventing motion sickness, the embodiment of this application uses non-contact motion sickness recognition processing based on behavioral characteristic data, which can improve the stability of motion sickness recognition processing and riding comfort, further enhancing the travel experience of the current target object.

[0006] In some embodiments, the device further includes a sensing module configured to collect behavioral feature data of the current target object on the seat module and transmit the behavioral feature data to the controller.

[0007] Thus, the device also includes a sensing module configured to collect behavioral feature data of the current target object on the seat module and transmit the behavioral feature data to the controller. In this way, by acquiring the behavioral feature data of the target object non-contactly through the sensing module and transmitting the behavioral feature data to the controller, a precise and continuous data source can be provided for subsequent object type recognition and motion sickness assessment.

[0008] In some embodiments, the sensing module includes an image acquisition device, an infrared sensor, and a processing unit; The image acquisition device is configured to acquire the pose data of the current target object; The infrared sensor is configured to acquire infrared image data of the current target object; The processing unit is configured to perform feature extraction processing on the attitude data and the infrared image data to obtain the behavioral feature data.

[0009] Thus, the perception module includes an image acquisition device, an infrared sensor, and a processing unit. The image acquisition device is configured to acquire the posture data of the current target object; the infrared sensor is configured to acquire the infrared image data of the current target object; and the processing unit is configured to perform feature extraction processing on the posture data and infrared image data to obtain behavioral feature data. In this way, based on the image acquisition device and infrared sensor, continuous and stable data acquisition can be achieved under all lighting conditions. Furthermore, by performing feature extraction processing on the posture data and infrared image data through the processing unit, behavioral feature data can be obtained, providing accurate basic data for subsequent identification of the current target object type and judgment of motion sickness.

[0010] In some implementations, the behavioral feature data includes body shape feature data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory and / or pupil diameter parameters.

[0011] Thus, behavioral characteristic data includes body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory, and / or pupil diameter parameters. By collecting body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory, and pupil diameter parameters, multi-dimensional data can be integrated to comprehensively determine the type of the current target object and its motion sickness status, improving the accuracy of type recognition and motion sickness identification, and providing solid data support for the controller to generate precise motion sickness protection commands.

[0012] In some embodiments, the controller includes a control unit and an algorithm processing unit; The control unit is configured to receive the behavioral characteristic data of the current target object; The algorithm processing unit is configured as follows: Based on the behavioral feature data, the type of the current target object on the seat module is identified, wherein the type of the current target object includes the first type and the second type; Based on a preset motion sickness recognition model, the behavioral feature data is processed for motion sickness recognition according to the type, and the motion sickness index is determined. If the motion sickness index is greater than a preset index threshold, it is determined that the current target object is motion sick. The control unit is also configured to generate the motion sickness protection command in the event that the current target object is experiencing motion sickness.

[0013] Thus, the controller includes a control unit and an algorithm processing unit. The control unit is configured to receive behavioral characteristic data of the current target object. The algorithm processing unit is configured to identify the type of the current target object on the seat module based on the behavioral characteristic data, wherein the type of the current target object includes a first type and a second type. Based on a preset motion sickness recognition model, the behavioral characteristic data is processed for motion sickness recognition according to the type to determine the motion sickness index. If the motion sickness index is greater than a preset index threshold, the current target object is determined to be motion sick. The control unit is also configured to generate a motion sickness protection command when the current target object is motion sick. In this way, by combining the type of the current target object and identifying and judging the behavioral characteristic data of the current target object based on the preset motion sickness recognition model corresponding to the type, a motion sickness index can be output to quantify the motion sickness state of the current target object, improve the accuracy of motion sickness recognition, reduce false positives and false negatives, and make subsequent motion sickness protection more targeted, thereby achieving proactive intervention.

[0014] In some embodiments, the motion sickness protection module includes an air conditioning unit, a seat vibration unit, an audio playback unit, and / or an aroma release unit; The air conditioning unit is configured to adjust the air supply temperature, air oxygen content, and / or humidity according to the motion sickness protection command; The seat vibration unit is configured to control the vehicle seat to vibrate in a preset mode corresponding to the target object according to the motion sickness protection command, wherein the preset mode includes a first mode corresponding to the first type and a second mode corresponding to the second type; The audio playback unit is configured to play a preset audio corresponding to the target object according to the motion sickness protection instruction, wherein the preset audio includes a first audio corresponding to the first type and a second audio corresponding to the second type; The fragrance release unit is configured to release a preset fragrance corresponding to the target object according to the motion sickness protection command, wherein the preset fragrance includes a first fragrance corresponding to the first type and a second fragrance corresponding to the second type.

[0015] Thus, the motion sickness protection module includes an air conditioning unit, a seat vibration unit, an audio playback unit, and / or a fragrance release unit; the air conditioning unit is configured to adjust the air supply temperature, air oxygen content, and / or humidity according to the motion sickness protection command; the seat vibration unit is configured to control the vehicle seat to vibrate in a preset mode corresponding to the target object according to the motion sickness protection command, wherein the preset mode includes a first mode corresponding to a first type and a second mode corresponding to a second type; the audio playback unit is configured to play a preset audio corresponding to the target object according to the motion sickness protection command, wherein the preset audio includes a first audio corresponding to a first type and a second audio corresponding to a second type; the fragrance release unit is configured to release a preset fragrance corresponding to the target object according to the motion sickness protection command, wherein the preset fragrance includes a first fragrance corresponding to a first type and a second fragrance corresponding to a second type. In this way, based on the current target object type, the air conditioning unit, seat vibration unit, audio playback unit, and fragrance release unit provide multi-dimensional coordinated motion sickness protection for the current target object. This allows the motion sickness protection to be adapted to the current target object, improve the motion sickness relief effect, achieve proactive motion sickness prevention, and thus enhance the safety and experience of riding.

[0016] In some implementations, the controller is further configured to: After the motion sickness protection module performs motion sickness protection on the current target object according to the motion sickness protection instruction, it records the execution parameters and feedback results. The preset motion sickness recognition model is updated based on the execution parameters and the feedback results.

[0017] Thus, after the motion sickness protection module performs motion sickness protection for the current target based on the motion sickness protection instruction, it records the execution parameters and feedback results; based on the execution parameters and feedback results, it updates the preset motion sickness recognition model. In this way, the preset motion sickness recognition model can be optimized based on the execution parameters and feedback results, improving the accuracy of motion sickness recognition and the effectiveness of intervention, realizing personalized motion sickness prevention intervention for different types of target objects, and thus improving the motion sickness prevention experience when traveling by car.

[0018] In some implementations, the controller is further configured to: The identified type is matched with the current removable interior compartment. If the type does not match the current removable cabin, a prompt instruction is generated to remind the target monitored object to replace the removable cabin.

[0019] Thus, the controller is also configured to match the identified type with the current removable cabin; if the type does not match the current removable cabin, a prompt instruction is generated to remind the monitored person to replace the removable cabin. This enables matching and verification between the removable cabin and the passenger type, eliminating safety hazards caused by human error in installation, and ensuring accurate correspondence between motion sickness protection and the target passenger type when the type does not match. This prevents motion sickness protection from malfunctioning due to mismatch between the removable cabin and the type, ensuring stable operation of the motion sickness protection function and comprehensively improving the safety and comfort of the passenger to a certain extent.

[0020] This application also provides a motion sickness prevention method, the method comprising: Based on the behavioral characteristic data of the current target object, the type of the current target object on the seat module is identified, wherein the type of the current target object includes the first type and the second type; Based on the type, motion sickness identification processing is performed on the behavioral feature data to determine whether the current target object is experiencing motion sickness. If the current target object experiences motion sickness, a motion sickness protection command is generated to control the motion sickness protection module to execute the command and provide motion sickness protection for the current target object.

[0021] Thus, based on the behavioral characteristic data of the current target object, the type of the current target object on the seat module is identified, including a first type and a second type. Based on the type, motion sickness detection processing is performed on the behavioral characteristic data to determine if the current target object is prone to motion sickness. If the current target object is prone to motion sickness, a motion sickness protection command is generated to control the motion sickness protection module to execute the command and provide motion sickness protection for the current target object. In this way, by identifying the type of the current target object through its behavioral characteristic data and performing motion sickness detection processing based on that type, differentiated identification and protection can be achieved based on the target object type, improving the accuracy of motion sickness detection, thereby enabling early intervention for motion sickness precursors, reducing the probability of motion sickness in the current target object, and improving the effectiveness of motion sickness protection and the passenger experience. Compared to invasive physiological monitoring methods for preventing motion sickness, this embodiment uses non-contact motion sickness detection processing based on behavioral characteristic data, which improves the stability of motion sickness detection processing and riding comfort, further enhancing the passenger experience.

[0022] This application provides a vehicle that includes the motion sickness protection device and implements the steps of the above method.

[0023] This application provides a computer-readable storage medium storing a computer program that, when executed by one or more processors, implements the steps of the above-described method.

[0024] This application also provides a computer program product comprising a computer program / instructions that, when executed by one or more processors, implement the steps of the above-described method.

[0025] The vehicle, computer-readable storage medium, and computer program product provided in this application identify the type of the current target object on the seat module based on the behavioral characteristic data of the current target object. The types of the current target object include a first type and a second type. Based on the type, motion sickness recognition processing is performed on the behavioral characteristic data to determine whether the current target object is prone to motion sickness. If the current target object is prone to motion sickness, a motion sickness protection command corresponding to the current target object is generated to control the motion sickness protection module to execute the command and provide motion sickness protection for the current target object. Thus, based on the detachable interior, a first interior cabin adapted to the first type and a second interior cabin adapted to the second type can be quickly adapted according to actual needs, meeting the riding needs of different types of target objects. Simultaneously, by identifying the type of the current target object through behavioral characteristic data and performing motion sickness recognition processing on the behavioral characteristic data based on the type, differentiated identification and protection can be achieved based on the target object type, improving the accuracy of motion sickness judgment. This allows for early intervention of motion sickness precursors, reducing the probability of motion sickness for the current target object, improving the effectiveness of motion sickness protection, and enhancing the riding experience of the current target object. Compared to invasive physiological monitoring methods for preventing motion sickness, the present application's implementation method uses non-contact motion sickness identification processing based on behavioral characteristic data, which can improve the stability of motion sickness identification processing and riding comfort, further enhancing the riding experience of the target audience.

Detailed Implementation

[0028] The embodiments of this application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the embodiments of this application, and should not be construed as limiting the embodiments of this application.

[0029] While regenerative braking systems in electric vehicles can effectively improve energy efficiency, their low-frequency operation can disrupt the sensory coordination between the vestibular and visual systems of occupants, leading to vestibular-visual sensory conflict and causing motion sickness. Furthermore, infants and small pets are special passenger groups in electric vehicles. Their physiological perception mechanisms differ from adults, and they lack the ability to express discomfort or actively operate onboard equipment, making it difficult for accompanying caregivers to detect motion sickness in a timely manner.

[0030] Among related technologies, motion sickness prevention technologies applied to address motion sickness mainly rely on the subjective feedback of passengers as the basis for intervention or on invasive sensors to monitor motion sickness status.

[0031] However, when the subjective feedback of passengers is used as the basis for intervention, passengers need to manually adjust the system through the vehicle's central control screen or trigger the anti-motion sickness intervention function by voice command. This relies on the passengers' autonomous feedback and operation, which cannot be adapted to the characteristics of infants and small pets who have no autonomous expression or device operation ability. Furthermore, the intervention is delayed and can only take effect after the motion sickness reaction occurs, so it cannot achieve the prospective prevention of motion sickness.

[0032] Invasive sensors collect physiological data through direct contact with the occupant's body, and algorithms analyze the data to determine motion sickness and then implement interventions. However, this contact-based monitoring method can physically irritate an infant's skin and easily trigger stress and resistance in small pets. Furthermore, the data acquisition accuracy is significantly affected by the occupant's posture and the way the sensor is worn, resulting in insufficient stability of physiological data acquisition and low accuracy in predicting motion sickness. Therefore, it cannot provide highly adaptable and safe motion sickness protection for infants and small pets, failing to meet the needs of real-world usage scenarios.

[0033] Motion sickness protection device 100, seat module 110, detachable inner cabin 111, first inner cabin 113, second inner cabin 114, seat base 112, controller 120, motion sickness protection module 130, sensing module 140 Based on the above issues, please refer to Figure 1 This application provides a motion sickness protection device 100, which includes a seat module 110, a controller 120, and a motion sickness protection module 130. The seat module 110 includes a detachable inner cabin 111 and a seat base 112. The detachable inner cabin 111 includes a first inner cabin 113 adapted to a first type and a second inner cabin 114 adapted to a second type. The first inner cabin 113 or the second inner cabin 114 can be detachably installed on the seat base 112. Controller 120 is configured as follows: Based on the behavioral characteristic data of the current target object, the type of the current target object on the seat module 110 is identified, wherein the type of the current target object includes a first type and a second type; Based on the type, motion sickness identification processing is performed on the behavioral feature data to determine whether the current target object is experiencing motion sickness. If the current target object is experiencing motion sickness, a motion sickness protection command corresponding to the current target object is generated to control the motion sickness protection module 130 to execute the motion sickness protection command and provide motion sickness protection for the current target object.

[0034] Specifically, the seat module 110 includes a fixed seat base 112 and a detachable inner cabin 111, which are used to adapt to different passengers. The detachable inner cabin 111 is a passenger cabin that can be quickly disassembled and assembled to meet the passenger needs of different passengers. The seat base 112 is the fixed frame part of the seat module 110, which provides an installation, positioning and locking structure for the detachable inner cabin 111 to ensure stability during driving.

[0035] Passengers can be divided into two types: the first type refers to infants or children, and the second type refers to pets such as small cats and dogs.

[0036] The detachable inner cabin 111 can be divided into a first inner cabin 113 and a second inner cabin 114 according to the type of passenger. The first inner cabin 113 is a passenger cabin adapted to the first type of passenger and can be equipped with safety protection structures such as seat belts and soft pads for infants and young children. The second inner cabin 114 is a passenger cabin for the second type of passenger and can be equipped with pet-friendly structures such as breathable mesh or adjustable leash for pets.

[0037] The controller 120 is the control unit of the device 100, and has the functions of data reception, type recognition, motion sickness judgment, and instruction generation.

[0038] The current target object refers to the passenger located in the current detachable interior 111.

[0039] Behavioral characteristic data refers to the collected external performance data of the target object, such as body shape, facial expressions, head movements, pupil changes, etc., which are used to determine the type of the current target object and its motion sickness status.

[0040] The motion sickness detection unit is used to analyze and calculate behavioral characteristic data to determine whether the current target subject is showing signs or symptoms of motion sickness.

[0041] The motion sickness protection command is a control signal generated by the controller 120 based on the current target object type and motion sickness status, which is used to drive the motion sickness protection module 130 to perform intervention operations.

[0042] The motion sickness protection module 130 is used to execute the motion sickness protection command generated by the controller 120 to implement motion sickness protection when the current target object is in a motion sickness state.

[0043] Depending on the needs of the person being cared for, the first inner cabin 113 and the second inner cabin 114 can be quickly disassembled and fixed to the seat base 112, allowing for switching between different types of passengers. For example, when traveling with an infant, the person being cared for can replace the detachable inner cabin 111 with the first inner cabin 113, which is suitable for infants and toddlers. When traveling with a pet, the person being cared for can replace the detachable inner cabin 111 with the second inner cabin 114, which is suitable for pets.

[0044] In one example, the first interior compartment 113 of type 1 is adapted as follows: Figure 2 As shown, it can be equipped with a built-in five-point seat belt system. The contact area between the shoulder strap and the waist belt is padded with memory foam. The shoulder strap tension is adjusted in conjunction with the camera to ensure safety and comfort during motion sickness intervention. The interior surface is covered with a waterproof coating and a removable anti-fouling cover is provided. The anti-fouling cover can be fixed with Velcro and can be replaced or cleaned regularly to ensure hygiene.

[0045] In one example, it adapts to the second type of second interior compartment 114, such as Figure 3 As shown, it can be equipped with an adjustable leash system. The leash system can be connected to the seat frame via a magnetic quick-release interface. The end of the leash has an anti-slip buckle to ensure the safety of the pet when moving around in the seat. At the same time, the bottom of the inner cabin is made of anti-slip and antibacterial soft padding, and the top is equipped with breathable mesh fabric to facilitate ventilation and reduce pet anxiety.

[0046] In one example, seat base 112 as Figure 4As shown, the seat base 112 is the universal frame of the seat. At the top center of the frame is a cylindrical magnetic positioning post, with four evenly distributed snap-fit ​​slots on its outer side. The snap-fit ​​of the seat base 112 can be either a rotating snap-fit ​​or a press-fit snap-fit, and the magnetic positioning post can be a D-shaped semi-cylinder; the configuration can be tailored to specific needs and is not limited here. Correspondingly, at the bottom of the detachable inner compartment 111, four elastic snaps can be installed at the positions corresponding to the frame snap-fit ​​slots. The magnetic positioning post, in conjunction with the elastic snaps, enables quick positioning and secure locking of the inner compartment, preventing it from shaking during driving.

[0047] In one example, the installation and disassembly process of the first inner compartment 113 or the second inner compartment 114 of the removable inner compartment 111 is as follows: Figure 5 As shown, taking the replacement of the first inner cabin 113 with the second inner cabin 114 as an example, the monitored person can first hold the handles in the middle of both sides of the old inner cabin, i.e. the first inner cabin 113, and press the push button on the inside of the inner cabin handle. The button pushes the buckle at the bottom of the inner cabin away from the buckle groove of the frame through the linkage until the buckle is completely disengaged from the locking position of the buckle groove. At the same time, while keeping the button pressed, pull the old inner cabin upward to completely separate the positioning hole at the bottom of the inner cabin from the cylindrical magnetic positioning post in the middle of the top of the universal frame, thus completing the disassembly of the old inner cabin. Then, the monitored object can select the corresponding new inner cabin, namely the second inner cabin 114, and align the positioning hole at the bottom of the new inner cabin with the cylindrical magnetic positioning post in the middle of the top of the universal frame. Under the action of magnetic force, the inner cabin will automatically center and position itself. At this time, the four buckles at the bottom of the inner cabin will be aligned with the four buckle slots on the frame. At the same time, the inner cabin will be pressed down and will slide down along the magnetic positioning post until the bottom of the inner cabin is in contact with the surface of the frame. During the pressing process, the wedge-shaped guide surface of the buckle head will contact the inclined surface at the entrance of the buckle slot. As the pressing force increases, the buckle will elastically deform inward under the guidance of the inclined surface and continue to slide down until the buckle reaches the locking position of the buckle slot. When the inner cabin is completely in contact with the frame, the buckle will pop outward under its own elastic restoring force and lock into the locking protrusion below the buckle slot to achieve automatic locking. Finally, after the new cabin is installed, the pressure sensor on the seat cushion detects the weight signal of the cabin, triggering the high-definition camera to start, collect pattern markings on the surface of the cabin and transmit them to the image processing unit, that is, to collect the behavioral feature data of the current target object, so as to provide a data basis for subsequent motion sickness recognition and processing.

[0048] When the current target object is detected to be located inside the detachable cockpit, the behavioral characteristic data of the current target object can be collected so that the controller 120 can identify the type of the current target object on the seat module 110 based on the behavioral characteristic data of the current target object; After the identification is completed, the controller 120 combines the identified type and performs motion sickness identification processing on the behavioral feature data according to the judgment criteria corresponding to the current type to determine whether the target object is in a motion sickness state. When it is determined that the current target object is motion sickness, the controller 120 immediately generates a motion sickness protection command that matches the type and transmits the command to the motion sickness protection module 130. After receiving the instruction, the motion sickness protection module 130 performs motion sickness protection operations to specifically alleviate motion sickness discomfort in infants or small pets.

[0049] Compared to invasive physiological monitoring methods for preventing motion sickness, the present application's implementation method uses non-contact motion sickness recognition based on behavioral characteristic data. This avoids the discomfort and resistance caused by invasive sensors, thereby improving the stability of motion sickness recognition and the comfort of riding, and further enhancing the riding experience of the target audience.

[0050] In summary, the embodiment of this application, based on the detachable interior cabin 111, can quickly adapt to the first interior cabin 113 (adapted to the first type) and the second interior cabin 114 (adapted to the second type) according to actual needs, meeting the travel needs of different types of target objects. Simultaneously, by identifying the behavioral characteristic data of the current target object to determine its type, and performing motion sickness recognition processing on the behavioral characteristic data based on the type, differentiated identification and protection can be achieved based on the target object type, improving the accuracy of motion sickness judgment. This allows for early intervention of motion sickness precursors, reducing the probability of motion sickness in the current target object, improving the motion sickness protection effect and the travel experience of the current target object. Compared to invasive physiological monitoring methods for preventing motion sickness, the embodiment of this application uses non-contact motion sickness recognition processing based on behavioral characteristic data, which can improve the stability of motion sickness recognition processing and riding comfort, further enhancing the travel experience of the current target object.

[0051] Please refer to it again. Figure 1 In some embodiments, the device 100 further includes a sensing module 140, which is configured to collect behavioral feature data of the current target object on the seat module 110 and transmit the behavioral feature data to the controller 120.

[0052] Specifically, the sensing module 140 refers to the component in the motion sickness protection device 100 that undertakes the dedicated data acquisition function. It is used to acquire the behavioral characteristic data of the target object and transmit the behavioral characteristic data to the controller 120, providing an accurate and continuous data source for subsequent object type recognition and motion sickness judgment.

[0053] Thus, the device 100 also includes a sensing module 140, which is configured to collect behavioral feature data of the current target object on the seat module 110 and transmit the behavioral feature data to the controller 120. In this way, by acquiring the behavioral feature data of the target object non-contactly through the sensing module 140 and transmitting the behavioral feature data to the controller 120, an accurate and continuous data source can be provided for subsequent object type recognition and motion sickness judgment.

[0054] In some embodiments, the sensing module 140 includes an image acquisition device, an infrared sensor, and a processing unit; The image acquisition device is configured to acquire the pose data of the current target object; The infrared sensor is configured to acquire infrared image data of the current target object; The processing unit is configured to perform feature extraction processing on attitude data and infrared image data to obtain behavioral feature data.

[0055] Specifically, the image acquisition device refers to the visible light acquisition hardware in the sensing module 140, which is used to capture the external shape and motion information of the target object under normal lighting, i.e., posture data.

[0056] The infrared sensor is an auxiliary acquisition hardware in the sensing module 140. It acquires infrared image data of the target object through infrared thermal imaging technology to compensate for acquisition gaps in special environments such as low light and night.

[0057] The processing unit is used to integrate, denoise, and extract features from the multi-source raw data collected by the image acquisition device and infrared sensor, and output standardized usable data, namely behavioral feature data.

[0058] Posture data is the external state data of a target object acquired by an image acquisition device, including intuitive posture information such as body outline, facial structure, head movement trajectory, and facial expression changes.

[0059] Infrared image data is infrared thermal imaging data of a target object collected by an infrared sensor. It can characterize the body temperature distribution and body contour of the target object and is not limited by lighting conditions.

[0060] Feature extraction processing is a standardized process in which the processing unit filters, fuses, and analyzes the original pose data and infrared image data to extract the core effective features.

[0061] Understandably, the image acquisition device can continuously acquire the posture data of the current target object, and fully capture key posture information such as body shape, face, head movement, and expression; the infrared sensor, as a supplementary acquisition component, can simultaneously acquire infrared image data of the target object to make up for the blind spots of visible light acquisition in low light and nighttime environments.

[0062] The perception module 140 may include an image acquisition device, an infrared sensor, and a processing device. It can acquire data in a dual-source non-contact manner through the image acquisition device and the infrared sensor, covering all lighting scenarios. The processing unit can perform feature extraction processing and output accurate and concise behavioral feature data, providing high-quality data support for the controller 120 to perform motion sickness recognition processing.

[0063] In one example, the image acquisition device is a camera, which can be installed on the upper edge of the front seat headrest, with a field of view covering the entire seat area; infrared sensors are located on both sides of the camera in a symmetrical arrangement.

[0064] In one example, a camera is used to capture in real time the facial expressions, head posture, eye movement features, and pupil changes of the target object inside the removable interior 111; an infrared sensor is used to compensate for image information under low light or nighttime conditions; and a microprocessor unit is used to preprocess, extract features, and encode the video stream. The processing module is connected to the image acquisition device and the infrared sensor, and is also electrically connected to the controller 120 via a wireless communication module. Based on the vehicle-mounted communication link, the processing module can stably and periodically send behavioral feature data to the controller 120, ensuring real-time, continuous, and delay-free data transmission. Thus, the perception module 140 includes an image acquisition device, an infrared sensor, and a processing unit. The image acquisition device is configured to acquire posture data of the current target object; the infrared sensor is configured to acquire infrared image data of the current target object; and the processing unit is configured to perform feature extraction processing on the posture data and infrared image data to obtain behavioral feature data. In this way, based on the image acquisition device and the infrared sensor, continuous and stable data acquisition can be achieved under all lighting conditions. Furthermore, by performing feature extraction processing on the posture data and infrared image data through the processing unit, behavioral feature data can be obtained, providing accurate basic data for subsequent identification of the current target object type and judgment of motion sickness.

[0065] In some implementations, behavioral characteristic data includes body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory and / or pupil diameter parameters.

[0066] Specifically, body shape feature data refers to the external morphological data of the current target object, such as body outline, size proportion, and overall posture, which can distinguish between the first type and the second type.

[0067] Facial structure data consists of facial feature data such as the distribution of facial organs, contour shape, and proportions of facial features of the current target object, which are used for type recognition and expression state determination.

[0068] Blink frequency data refers to the number of times a target object blinks per unit of time, and can be used as a behavioral indicator to characterize motion sickness, discomfort, and emotional tension.

[0069] Mouth corner angle data refers to the upward and downward angles and the range of change of the current target object's mouth corners, which are used to judge facial expressions and motion sickness symptoms.

[0070] Head movement trajectory is the movement data of the target object's head, such as the movement path, shaking frequency, and swing amplitude, which is used to determine motion sickness.

[0071] The pupil diameter parameter is the size and fluctuation pattern of the pupil's contraction and expansion in the current target object. It can directly characterize the vestibular system state related to motion sickness and thus determine the tendency to motion sickness.

[0072] Understandably, behavioral characteristic data includes body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory, pupil diameter parameters, etc., which can be acquired non-contactly through image acquisition devices and infrared sensors to distinguish between the first type and the second type, as well as to identify the precursors of motion sickness.

[0073] By collecting body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory, and pupil diameter parameters, multi-dimensional data can be integrated to comprehensively determine the type of the current target object and the motion sickness status, thereby improving the accuracy of type recognition and motion sickness recognition.

[0074] In one example, the controller 120 can first accurately identify the type of the target object based on body shape feature data and facial structure data. Then, by combining features such as blink frequency data, mouth corner angle data, head movement trajectory and pupil diameter parameters, it can achieve multi-feature cross-validation, avoid single data errors, ensure the accuracy of type recognition and motion sickness determination, and provide solid data support for the controller 120 to generate accurate motion sickness protection commands.

[0075] Thus, behavioral characteristic data includes body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory, and / or pupil diameter parameters. By collecting body shape data, facial structure data, blink frequency data, mouth corner angle data, head movement trajectory, and pupil diameter parameters, multi-dimensional data can be integrated to comprehensively determine the type of the current target object and its motion sickness status, improving the accuracy of type recognition and motion sickness identification, and providing solid data support for the controller 120 to generate precise motion sickness protection commands.

[0076] In some implementations, the controller 120 includes a control unit and an algorithm processing unit; The control unit is configured to receive behavioral characteristic data of the current target object; The algorithm processing unit is configured as follows: Based on behavioral characteristic data, the type of the current target object on the seat module 110 is identified, wherein the type of the current target object includes a first type and a second type; Based on a preset motion sickness recognition model, motion sickness recognition processing is performed on behavioral feature data according to type to determine the motion sickness index; If the motion sickness index is greater than a preset threshold, the current target is determined to be motion sick. The control unit is also configured to generate motion sickness protection commands if the current target object is experiencing motion sickness.

[0077] Specifically, the control unit is the execution module in the controller 120 responsible for data reception, instruction scheduling and output.

[0078] The algorithm processing unit is an intelligent computing module built into the controller 120. By incorporating deep learning algorithms, it can realize target object type recognition, motion sickness index calculation and status determination.

[0079] The preset motion sickness recognition model refers to a deep learning model that is pre-trained based on the motion sickness behavior characteristics of infants and small pets. Differentiated judgment rules can be set for different types of target objects, such as motion sickness recognition and protection for pets in pet mode, and motion sickness recognition and protection for infants and young children in children's mode.

[0080] The motion sickness index is a quantitative value calculated and output by the algorithm processing unit through the model, used to characterize the strength of the motion sickness tendency of the target object.

[0081] The preset index threshold is a pre-set critical value for motion sickness, which is a quantitative standard for determining whether the target has entered a state of motion sickness.

[0082] Based on a preset motion sickness recognition model, it can identify the type, calculate the motion sickness index, and compare thresholds to accurately determine the motion sickness state and trigger corresponding protection commands.

[0083] Understandably, the control unit, as the interface for data and instructions, can receive multi-dimensional behavioral feature data transmitted by the sensing module 140 in real time, providing a stable data source for subsequent processing; As a computing module, the algorithm processing unit can first accurately identify the type of the current target object based on features such as body shape and facial structure in the behavioral feature data, such as an infant (type 1) or a small pet (type 2). After identification, the algorithm processing unit calls the preset motion sickness recognition model that matches the type, inputs the behavioral feature data into the model to perform motion sickness recognition processing, and generates a quantified motion sickness index through model calculation. The motion sickness index is then compared with a preset index threshold. If the motion sickness index exceeds the preset threshold, the target object is considered to be in a state of motion sickness. The determination result is synchronized to the control unit so that a motion sickness protection command adapted to the current target object type can be quickly generated and transmitted to the motion sickness protection module 130 for intervention.

[0084] Thus, the controller 120 includes a control unit and an algorithm processing unit; the control unit is configured to receive behavioral feature data of the current target object; the algorithm processing unit is configured to identify the type of the current target object on the seat module 110 based on the behavioral feature data, wherein the type of the current target object includes a first type and a second type; based on a preset motion sickness recognition model, the behavioral feature data is processed for motion sickness recognition according to the type to determine the motion sickness index; if the motion sickness index is greater than a preset index threshold, the current target object is determined to be motion sick; the control unit is also configured to generate a motion sickness protection command when the current target object is motion sick. In this way, by combining the type of the current target object and identifying and judging the behavioral feature data of the current target object based on the preset motion sickness recognition model corresponding to the type, a motion sickness index can be output to quantify the motion sickness state of the current target object, improve the accuracy of motion sickness recognition, reduce false positives and false negatives, and make subsequent motion sickness protection more targeted, thereby achieving proactive intervention.

[0085] In some embodiments, the motion sickness protection module 130 includes an air conditioning unit, a seat vibration unit, an audio playback unit, and / or an aroma release unit; The air conditioning unit is configured to adjust the air supply temperature, oxygen content, and / or humidity according to motion sickness protection instructions; The seat vibration unit is configured to control the vehicle seat to vibrate in a preset mode corresponding to the target object according to the motion sickness protection command, wherein the preset mode includes a first mode corresponding to a first type and a second mode corresponding to a second type; The audio playback unit is configured to play preset audio corresponding to the target object according to the motion sickness protection instruction, wherein the preset audio includes a first audio corresponding to a first type and a second audio corresponding to a second type; The fragrance release unit is configured to release a preset fragrance corresponding to the target object according to the motion sickness protection instruction. The preset fragrance includes a first fragrance corresponding to a first type and a second fragrance corresponding to a second type.

[0086] Specifically, the air conditioning unit is a control component in the motion sickness protection module 130 that interfaces with the vehicle's air conditioning system to optimize the temperature, humidity, and oxygen content of the cabin air and improve the riding environment.

[0087] A seat vibration unit is a vibration actuator that can be embedded in the seat cushion and backrest to provide physical relief and support to the target object through a preset vibration rhythm.

[0088] An audio playback unit is an in-vehicle audio output component used to play soothing audio tailored to the target audience, alleviating the anxiety caused by motion sickness.

[0089] A fragrance release unit is a car fragrance release component that may include a dedicated fragrance reservoir to control the release of non-irritating and soothing scents.

[0090] Preset modes refer to the vibration rhythm of the seat set for different target objects. For example, the first mode is a gentle vibration like a baby cradle, and the second mode is a low-frequency soothing vibration for small pets.

[0091] Preset audio is a pre-set exclusive audio that adapts to the auditory preferences of the target audience. For example, the first audio is soothing hypnotic music for babies, and the second audio is calming white noise or heart rate rhythm sounds for pets.

[0092] The preset fragrances are safe fragrances that are pre-set to match the physiological characteristics of the target audience. The first fragrance is a mild floral and fruity scent that is non-irritating to babies, and the second fragrance is a pet-friendly, alcohol-free herbal scent.

[0093] Based on the motion sickness protection instructions issued by the controller 120, the air conditioning unit, seat vibration unit, audio playback unit, and fragrance release unit can all execute exclusive modes according to the different types of infants or small pets, forming a multi-dimensional and personalized motion sickness protection solution.

[0094] In one example, the air conditioning unit can precisely adjust the air supply temperature, oxygen content, and humidity according to motion sickness protection instructions, accelerating air circulation and alleviating vestibular discomfort from an environmental perspective; the seat vibration unit switches to a dedicated vibration mode according to the current target object type, providing a cradle-like gentle rhythmic vibration for the first type, namely infants, and a low-frequency, stable, and soothing vibration for the second type, namely small pets, reducing sensory stimulation caused by vehicle bumps; the fragrance release unit releases a suitable preset fragrance, using a formula that is non-irritating to infants and respiratory-friendly to pets, helping to alleviate discomfort from an olfactory perspective.

[0095] In one example, the priorities of the air conditioning unit, seat vibration unit, audio playback unit, and fragrance release unit can be preset. For example, the air conditioning unit can be set to have a higher priority. When the current target object's motion sickness is mild, the cabin environment can be optimized through the air conditioning unit first. When the motion sickness is severe, the air conditioning unit, seat vibration unit, audio playback unit, and fragrance release unit can intervene in the vehicle environment in all dimensions to improve the anti-motion sickness effect of the current target object.

[0096] Thus, the motion sickness protection module 130 includes an air conditioning unit, a seat vibration unit, an audio playback unit, and / or a fragrance release unit; the air conditioning unit is configured to adjust the air supply temperature, air oxygen content, and / or humidity according to the motion sickness protection command; the seat vibration unit is configured to control the vehicle seat to vibrate in a preset mode corresponding to the target object according to the motion sickness protection command, wherein the preset mode includes a first mode corresponding to a first type and a second mode corresponding to a second type; the audio playback unit is configured to play a preset audio corresponding to the target object according to the motion sickness protection command, wherein the preset audio includes a first audio corresponding to a first type and a second audio corresponding to a second type; the fragrance release unit is configured to release a preset fragrance corresponding to the target object according to the motion sickness protection command, wherein the preset fragrance includes a first fragrance corresponding to a first type and a second fragrance corresponding to a second type. In this way, based on the current target object type, the air conditioning unit, seat vibration unit, audio playback unit, and fragrance release unit provide multi-dimensional coordinated motion sickness protection for the current target object. This allows the motion sickness protection to be adapted to the current target object, improve the motion sickness relief effect, achieve proactive motion sickness prevention, and thus enhance the safety and experience of riding.

[0097] In some implementations, the controller 120 is further configured to: After the motion sickness protection module 130 performs motion sickness protection on the current target object according to the motion sickness protection instruction, it records the execution parameters and feedback results. Update the preset motion sickness recognition model based on the execution parameters and feedback results.

[0098] Specifically, the execution parameters refer to the quantitative operational data of the motion sickness protection module 130 when it performs motion sickness protection intervention, such as air conditioning temperature and humidity, air oxygen content, seat vibration frequency, seat vibration duration, audio type, audio volume, fragrance concentration, fragrance release duration, intervention start time, execution duration, and other data.

[0099] The feedback results include the subjective evaluation results of the monitored subjects and the current improvement results of the target subjects' status. For example, the intervention effect score submitted by the monitored subjects through the vehicle central control or mobile terminal, and the improvement data of the current target subjects' behavioral characteristics after the motion sickness protection module 130 performs the intervention motion sickness protection operation.

[0100] After the motion sickness protection module 130 performs the motion sickness protection intervention, the controller 120 can automatically record all the execution parameters of this intervention, collect subjective and objective feedback results simultaneously, and dynamically update the preset motion sickness recognition model based on these real operating data, so as to realize the self-iteration and continuous optimization of the preset motion sickness recognition model and adaptive anti-motion sickness control.

[0101] In one example, after the motion sickness protection module 130 completes the intervention of air conditioning, seat vibration, audio playback, and fragrance release according to the motion sickness protection command, the controller 120 can immediately start the data recording function to completely retain all the execution parameters of this intervention and accurately restore the quantitative indicators of the entire intervention process. At the same time, the controller 120 obtains feedback results bidirectionally. On the one hand, it receives the subjective evaluation of the intervention effect submitted by the monitored subject through the vehicle central control screen or mobile terminal. On the other hand, it collects the changes in the behavioral characteristics data of the current target subject after the intervention monitored by the perception module 140.

[0102] The controller 120 integrates the execution parameters and feedback results, conducts data analysis through the built-in learning algorithm, accurately locates the optimization direction of feature weights, motion sickness index thresholds, and type determination rules in the model, and updates the preset motion sickness recognition model in real time accordingly.

[0103] The updated model will be directly applied to the type identification and motion sickness judgment of the next trip, so that the parameters such as identification accuracy, intervention timing and intervention strategy will continue to fit the individual characteristics of the target object, realize the dynamic iterative optimization of the model and the continuous adaptive optimization of the motion sickness protection device 100.

[0104] Thus, after the motion sickness protection module 130 performs motion sickness protection on the current target object according to the motion sickness protection instruction, it records the execution parameters and feedback results; based on the execution parameters and feedback results, it updates the preset motion sickness recognition model. In this way, the preset motion sickness recognition model can be optimized according to the execution parameters and feedback results, improving the accuracy of motion sickness recognition and the effectiveness of intervention, realizing personalized motion sickness prevention intervention for different types of target objects, and thus improving the motion sickness prevention experience when traveling.

[0105] In some implementations, the controller 120 is further configured to: Match the identified type with the current removable interior compartment 111; If the type does not match the current removable interior 111, a prompt instruction is generated to remind the target monitored object to replace the removable interior 111.

[0106] Specifically, the matching process is used to compare the type of the target object identified by the sensing module 140 with the type of the currently installed removable cabin 111.

[0107] The prompt instruction refers to the control signal generated by the controller 120 to remind the guardian.

[0108] The target of guardianship refers to the guardian of an infant or small pet, who is the main person responsible for receiving prompts and performing the replacement of the removable inner compartment 111.

[0109] Understandably, the detachable inner cabin 111 of the motion sickness protection device 100 in this application embodiment can be disassembled and replaced by the target monitored object, which may lead to the problem of incorrect installation of the inner cabin. For example, a pet inner cabin may be installed when an infant is riding, or an infant inner cabin may be installed when a small pet is riding. That is, a second inner cabin 114 may be installed when a first type of target object is riding, and a first inner cabin 113 may be installed when a second type of target object is riding.

[0110] In one example, misconfiguration can cause the safety structure of the first cabin 113 or the second cabin 114 to fail, such as preventing infants from using five-point harnesses or pets from using leash systems, posing a safety hazard to passengers. At the same time, misconfiguration will cause motion sickness intervention strategies to be mismatched with the target population, significantly reducing the effectiveness of interventions. Furthermore, without an automatic detection and reminder mechanism, guardians will find it difficult to detect mismatches in a timely manner, failing to ensure the safety and comfort of infants and pets during travel.

[0111] The controller 120 can automatically compare the type of the target object with the current cabin type. If the two do not match, it will immediately generate a prompt instruction to remind the target monitored object to change to the corresponding cabin in time, so as to ensure that the passenger and cabin types are accurately matched.

[0112] Therefore, in actual motion sickness protection scenarios, after the monitored object replaces the detachable inner cabin 111, that is, after the first inner cabin 113 or the second inner cabin 114 is installed and locked on the seat base 112, in response to the electrical signal detected by the detection component of the seat base 112 and transmitted to the controller 120, that is, the installation signal indicating that the inner cabin has been installed in place, the current target object type and the currently installed detachable inner cabin 111 type are matched. It can also match the type of the current target object with the type of the currently installed detachable interior 111 after identifying that a target object is riding in the detachable interior 111. The identification cycle can also be set to match the current target object type with the currently installed detachable interior 111 type. There are no restrictions here, and it can be set according to the actual situation.

[0113] In one example, the seat base 112 may include a pressure sensor and a snap-fit ​​detection component. Please refer again. Figure 5 After the guardian, i.e. the target person under guardianship, installs or fixes the first inner cabin 113 or the second inner cabin 114 on the seat base 112, the pressure sensor and buckle detection component of the seat base 112 will detect the inner cabin locking state and generate an inner cabin installation signal to be transmitted to the controller 120. After receiving the installation signal, the controller 120 immediately calls the current target object type that has been identified by the sensing module 140 and performs matching processing with the currently installed detachable cabin type 111, that is, to determine whether the passenger and cabin mode match. If the type of the identified object matches the type of the cabin, the match is considered successful, and subsequent motion sickness identification and protection can be started normally. For example, a motion sickness protection activation prompt will be displayed and the vehicle voice will announce that the target monitored object is undergoing motion sickness protection. If the type of the identified object is inconsistent with the type of the cabin, the controller 120 can immediately generate a prompt instruction and transmit it to the vehicle user interaction system. The system will then clearly inform the target monitored object that the current cabin does not match the passenger and that a detachable cabin of the corresponding type needs to be replaced through a text pop-up on the central control screen or a voice broadcast.

[0114] Thus, the controller 120 is also configured to match the identified type with the current removable cabin 111; if the type does not match the current removable cabin 111, a prompt instruction is generated to remind the monitored person to replace the removable cabin 111. This enables matching and verification between the removable cabin 111 and the type of the passenger, eliminating safety hazards caused by human error in installation, and generating a prompt instruction when the type does not match ensures accurate correspondence between motion sickness protection and the target person's type. This avoids motion sickness protection failure due to mismatch between the removable cabin 111 and the type, ensuring stable operation of the motion sickness protection function and comprehensively improving the safety and comfort of the passenger to a certain extent.

[0115] Please see Figure 6 The present application also provides a motion sickness protection method, the method comprising: 01: Based on the behavioral characteristic data of the current target object, identify the type of the current target object on the seat module 110, wherein the type of the current target object includes a first type and a second type; 02: Based on the type, perform motion sickness recognition processing on the behavioral feature data to determine whether the current target object is prone to motion sickness; 03: If the current target object is experiencing motion sickness, generate a motion sickness protection command to control the motion sickness protection module 130 to execute the motion sickness protection command and provide motion sickness protection for the current target object.

[0116] The present application provides a vehicle including the aforementioned motion sickness protection device 100. Specifically, the motion sickness protection device 100 includes a controller 120 for implementing the aforementioned motion sickness protection method.

[0117] Specifically, the steps of the motion sickness protection method in this application are similar to those of the motion sickness protection device 100 described above. Please refer to the description of the motion sickness protection device 100 above, which will not be repeated here.

[0118] Thus, based on the behavioral characteristic data of the current target object, the type of the current target object on the seat module 110 is identified, including a first type and a second type. Based on the type, motion sickness detection processing is performed on the behavioral characteristic data to determine if the current target object is prone to motion sickness. If the current target object is prone to motion sickness, a motion sickness protection command is generated to control the motion sickness protection module 130 to execute the command and provide motion sickness protection for the current target object. In this way, by identifying the behavioral characteristic data of the current target object to determine its type, and performing motion sickness detection processing on the behavioral characteristic data based on the type, differentiated identification and protection can be achieved based on the target object type, improving the accuracy of motion sickness judgment, thereby enabling early intervention for motion sickness precursors, reducing the probability of motion sickness in the current target object, and improving the effectiveness of motion sickness protection and the travel experience of the current target object. Compared to invasive physiological monitoring methods for preventing motion sickness, the embodiment of this application uses non-contact motion sickness detection processing based on behavioral characteristic data, which can improve the stability of motion sickness detection processing and riding comfort, further enhancing the travel experience of the current target object.

[0119] The following is Figure 7 For example, the flow of the motion sickness protection method according to the embodiments of this application will be described: First, after the vehicle system is started and initialized, the control device, namely the controller 120 in this embodiment, can acquire the input signals from the camera, infrared sensor and cabin environment sensor to establish a basic behavioral feature dataset, namely the behavioral feature data in this embodiment. Then, the control device executes the passenger recognition algorithm, determines the current passenger type as an infant or a small pet based on the body shape, facial structure and infrared thermal imaging captured by the camera, and switches to the corresponding working mode accordingly. Next, the motion sickness detection phase begins. The control device periodically extracts characteristic parameters such as the frequency of eye closure, changes in the angle of the corners of the mouth, head movement trajectory, and pupil diameter fluctuations. These parameters are then combined with physiological indicators, such as respiratory rhythm or heart rate changes, for comprehensive judgment. When the overall motion sickness index exceeds a preset threshold, the system determines that the passenger is in a state of impending motion sickness. Then, the control unit first sends a warning message to the driver's center console screen, alerting the caregiver to the passenger's condition; subsequently, it activates the environmental intervention module, implementing differentiated control strategies based on passenger type. In child mode, the seat massage module provides gentle rhythmic support combined with cradle-like vibration, the audio system plays soothing music, the air conditioning system optimizes air circulation and oxygen levels, and the fragrance system releases a light floral and fruity scent. In pet mode, the system plays low-frequency music to alleviate the pet's discomfort, and the fragrance system switches to an animal-friendly formula (such as an alcohol-free herbal scent) to suppress anxiety.

[0120] Then, when the navigation system detects congested or bumpy road sections, the control unit calculates the motion sickness risk index in advance and initiates predictive intervention. The air conditioning, vibration frequency, and music rhythm will be dynamically adjusted according to vehicle speed and road conditions to avoid motion sickness.

[0121] Finally, after each trip, the control device records the intervention start time, execution duration, effect evaluation, and guardian feedback. Through reinforcement learning algorithms, it updates the individual model parameters and intervention thresholds, enabling the system to more accurately predict and intervene in motion sickness during the next trip.

[0122] This application also provides a computer-readable storage medium having a computer program stored thereon. When the computer program is executed by a processor, it implements the steps of the motion sickness prevention method described above.

[0123] This application also provides a computer program product, including a computer program / instructions. When the computer program / instructions are executed by a processor, the steps of the motion sickness protection method described above can be implemented.
