[0054] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0055] Motion sickness, also known as motion sickness, is a common physiological reaction, mainly manifested as dizziness, nausea, and vomiting. It is usually triggered during vehicle travel due to a lack of coordination between vision, vestibular sense, and proprioception.

[0056] Traditional methods for relieving motion sickness mainly include medication, visual compensation, and behavioral adjustments. While medication is effective, it has side effects such as drowsiness and dry mouth, making it unsuitable for long-term use. Visual compensation (such as setting a visual focus inside the vehicle) can alleviate motion sickness symptoms to some extent, but its effectiveness is limited and it cannot monitor the user's physiological state in real time. Behavioral adjustments (such as deep breathing and resting with eyes closed) rely on the user's subjective awareness, making it difficult to take timely measures in the early stages of motion sickness.

[0057] With the development of biomedical engineering technology, electroencephalography (EEG) technology is increasingly being applied to physiological state monitoring. EEG signals reflect the brain's electrical activity; by analyzing specific frequency bands of EEG signals in brain regions associated with motion sickness, it is possible to monitor a user's physiological state in real time and determine whether the user is experiencing motion sickness. This technology can not only provide early warnings but also automatically adjust the vehicle's interior environment based on the user's specific situation, such as adjusting the seat, changing the vehicle speed, or playing specific music to help alleviate motion sickness discomfort.

[0058] This application provides a motion sickness control method, storage medium, program product, device, system, and vehicle. It is an integrated EEG monitoring-analysis-regulation technology located in the vehicle's headrest, used to alleviate motion sickness in users. This application places highly sensitive EEG electrodes in the headrest to collect the user's EEG signals in real time and analyze these signals to determine if the user is experiencing motion sickness. Once motion sickness signs are detected, corresponding measures to alleviate it are automatically taken, such as adjusting the vehicle's interior environment, playing soothing music, or reminding the user to rest. This application not only monitors the user's physiological state in real time but also performs closed-loop regulation, assessing the effectiveness of implemented measures and making timely adjustments, achieving personalized customization of motion sickness relief measures and effectively improving user comfort. Furthermore, weak electrical stimulation can be applied to motion sickness-related brain regions through the EEG electrodes to regulate neural activity, thereby alleviating motion sickness.

[0059] The embodiments of the present application consider the actual application scenarios of vehicles to ensure the integration and compatibility of the device. By seamlessly docking with the intelligent system of the vehicle, it can work cooperatively with other vehicle-mounted devices (such as air conditioners, stereos, seats, etc.) to provide more comprehensive driving assistance functions. This integrated solution is not only suitable for traditional vehicles but also can be adapted to autonomous vehicles, providing a new direction and technical support for the development of future intelligent transportation.

[0060] The embodiments of the present application provide an efficient, intelligent and personalized solution for solving the problem of car sickness through innovative electroencephalogram monitoring-analysis-regulation integrated technology, which helps to improve the travel experience of users and enhance the level of traffic safety.

[0061] According to a first aspect of the present application, the embodiments of the present application provide a car sickness control method.

[0062] Please refer to Figure 1 , Figure 1 is a flowchart of a car sickness control method provided by the embodiments of the present application. As Figure 1 shown, the car sickness control method can include the following step S100.

[0063] Step S100: In the case that it is determined based on the first electroencephalogram signal that the first user is in a car sickness state, performing a car sickness suppression operation; wherein the first user is a user using a first headrest, and the first electroencephalogram signal is an electroencephalogram signal collected by the first headrest for the first user.

[0064] The headrest can be arranged above the seat in the vehicle, such as above the seat back. For the connection relationship and positional relationship of the seat and the headrest, please refer to the following embodiments, which will not be described here. The first headrest can be a headrest at any seat position in the vehicle, or the first headrest can be a headrest at a specific seat position in the vehicle, which is not limited by the embodiments of the present application. For example, the first headrest can be a headrest at a main driver seat position, a co-driver seat position or a rear seat position in the vehicle; or the first headrest can be a headrest at a co-driver seat position or a rear seat position except the main driver seat position in the vehicle.

[0065] For example, the first headrest can collect the brain electrical signals of the first user, i.e., the first brain electrical signals. The brain electrical signals are a comprehensive reflection of the electrical activity of neurons, are generated by the exchange of ions inside and outside the cell membrane of a large number of neurons, and are recorded on the scalp or cerebral cortex surface. The brain electrical signals reflect the activity state and functional characteristics of different regions of the brain, change with the individual's physiological state, pathological state, and cognitive activity, and are an important indicator for detecting the function of the central nervous system. Since the user (including the driver and / or the passenger) is in close contact with the headrest when riding the vehicle, the headrest of the present application can collect the brain electrical signals of the user in real time, which is simple and convenient, and does not require the user to wear or wear a brain electrical signal detection device, thereby improving the detection efficiency of the brain electrical signals.

[0066] Based on the analysis and processing of the first brain electrical signals, it can be detected whether the first user is in a car sickness state. Since different regions of the brain will have specific activity changes during car sickness, these regions include the occipital lobe area responsible for visual input, the parietal lobe area and the central area involved in the integration of proprioception and vestibular input, etc., so the brain electrical signals can be used to detect whether the user is in a car sickness state. The specific detection method of the car sickness state in the present application is not limited, and can be flexibly set according to the needs in actual application. For example, the first brain electrical signals can be compared with the brain electrical signals of the user in a normal state to detect whether the first user is in a car sickness state; or the first brain electrical signals can be input into an artificial intelligence detection model, such as a deep learning model or a machine learning model, to output a car sickness detection result to indicate whether the first user is in a car sickness state. For other descriptions of the detection method of the car sickness state, please refer to the following embodiments, which will not be described here.

[0067] When the first user is in a car sickness state, the present application timely performs a car sickness suppression operation to alleviate the car sickness state of the first user. The specific type of the car sickness suppression operation in the present application is not limited, and can be flexibly set according to the needs in actual application. The car sickness suppression operation can include a plurality of suppression operations, and the present application can sequentially perform the plurality of suppression operations or synchronously perform the plurality of suppression operations to ensure effective alleviation of the car sickness state. For other descriptions of the car sickness suppression operation, please refer to the following embodiments, which will not be described here.

[0068] In summary, the technical scheme provided by the embodiments of the present application collects the brain electrical signals of a user through a headrest in a vehicle, detects whether the user is in a car sickness state based on analysis and processing of the brain electrical signals, and executes a car sickness suppression operation in a timely manner in the case that the user is in a car sickness state. The embodiments of the present application realize real-time intelligent detection of a car sickness state through collection of brain electrical signals by a headrest, and realize timely and effective relief of a car sickness state through a car sickness suppression operation, which helps to improve the travel experience of a user and improve the comfort and safety of vehicle driving. In addition, the embodiments of the present application collect brain electrical signals through a headrest to detect a car sickness state of a user, without the need for the user to additionally wear or wear a detection device of brain electrical signals, which improves the detection efficiency of brain electrical signals and helps to efficiently detect and relieve a car sickness state.

[0069] In some embodiments, the car sickness control method further includes: performing data preprocessing on the first brain electrical signals. The first brain electrical signals after data preprocessing are used to detect whether the first user is in a car sickness state.

[0070] Since brain electrical signals usually contain various noises or interferences, such as electrode noise, muscle activity, eye movement, electrocardiogram, and environmental electromagnetic interference, these noises or interferences will mask useful information in the brain electrical signals and affect the accuracy of subsequent car sickness state detection, so it is necessary to perform data preprocessing to improve the quality of brain electrical data and further improve the accuracy of subsequent analysis and detection.

[0071] The embodiments of the present application do not limit the specific way of data preprocessing, which can be flexibly set according to the needs in actual application. For example, in some embodiments, the data preprocessing includes at least one of the following: re-reference processing, high-pass filtering processing, low-pass filtering processing, bad segment removal processing, artifact removal processing, and data segmentation processing. Through multi-dimensional data preprocessing, the quality of brain electrical signals can be effectively improved, which helps to extract clearer and more accurate physiological features and provides a reliable data basis for subsequent analysis and detection of a car sickness state.

[0072] The recording of brain electrical signals is usually based on the relative potential difference of multiple electrodes. During recording, the potential of each electrode is taken as the reference potential of a reference electrode. Re-reference refers to changing the setting of the reference electrode to achieve better signal analysis purposes.

[0073] High-pass filtering is a filtering method that allows high-frequency signals to pass through while attenuating low-frequency signals, which can remove the low-frequency drift of brain electrical signals, i.e., the offset of the baseline of brain electrical signals caused by slow time changes.

[0074] Low-pass filtering is a filtering method that allows low-frequency signals to pass through while attenuating high-frequency signals, which can remove high-frequency noise of brain electrical signals, such as noise caused by electromagnetic interference, poor electrode contact, etc.

[0075] In the actual process of collecting the electroencephalogram signal, some poor quality signal segments may occur due to various reasons, such as bad segments caused by electrode falling off, sudden large motion of the user, strong external electromagnetic interference, etc. These bad segments seriously affect subsequent analysis, and therefore need to be removed or corrected through bad segment removal processing.

[0076] In the electroencephalogram signal, electrooculogram, electromyogram and electrocardiogram and other artifact signals are often mixed, which interfere with the analysis of the electroencephalogram signal. Through independent component analysis (ICA), the mixed signal can be decomposed into independent components, and then according to the characteristics (such as waveform, frequency distribution, distribution on the scalp electrode, etc.) of the components, it can be identified which components are electrooculogram, electromyogram and electrocardiogram and other artifact components, and then the artifact components are removed from the data, so as to obtain a purer electroencephalogram signal.

[0077] Data segmentation is to divide the continuous electroencephalogram signal into multiple small segments according to certain rules, so as to facilitate subsequent analysis.

[0078] In some embodiments, the above anti-motion sickness control method further includes: detecting whether the first user is in the anti-motion sickness state according to the first electroencephalogram signal and the reference electroencephalogram data.

[0079] The reference electroencephalogram data refers to the electroencephalogram data of the user in a normal state (such as a non-anti-motion sickness state). The reference electroencephalogram data can be the electroencephalogram signal of the user in the normal state, or can be a specific frequency band feature extracted from the electroencephalogram signal of the user in the normal state, and the embodiments of the present application do not limit this. In addition, the reference electroencephalogram data can be the electroencephalogram data of the first user, or can be the electroencephalogram data of other users, and the embodiments of the present application do not limit this. By combining the reference electroencephalogram data in the normal state, the comparison between the first electroencephalogram signal and the reference electroencephalogram data can be realized, so as to facilitate effective and accurate detection of whether the first user is in the anti-motion sickness state.

[0080] In some embodiments, the above detecting whether the first user is in the anti-motion sickness state according to the first electroencephalogram signal and the reference electroencephalogram data includes: extracting a target frequency band feature from the first electroencephalogram signal; and detecting whether the first user is in the anti-motion sickness state according to the comparison between the target frequency band feature and the reference electroencephalogram data.

[0081] By extracting target frequency band features from the first electroencephalogram signal and comparing the target frequency band features with reference electroencephalogram data, the car sickness state can be quickly and accurately detected. Among them, the target frequency band features can focus on the electroencephalogram features of the brain regions related to the vestibular system, motor system and sensory system of the brain, and the target frequency band features can be extracted from the electroencephalogram features of these brain regions. In some embodiments, the target frequency band features include at least one of the following: delta wave, theta wave, alpha wave, beta wave and gamma wave. The target frequency band features of these brain regions can also be included in the reference electroencephalogram data. By comparing the target frequency band features in the first electroencephalogram signal with the target frequency band features in the reference electroencephalogram data, if they are not the same or the difference between them exceeds the set range, it is considered that the first user is in a car sickness state; if they are the same or the difference between them does not exceed the set range, it is considered that the first user is in a normal state (such as a non-car sickness state).

[0082] In some embodiments, the above car sickness control method further comprises: inputting the first electroencephalogram signal into a car sickness detection model to make the car sickness detection model output a car sickness detection result; wherein the car sickness detection result is used to indicate whether the first user is in a car sickness state.

[0083] The car sickness detection model can be an artificial intelligence model, such as a deep learning model or a machine learning model, such as a convolutional neural network, a recurrent neural network, etc. By using the car sickness detection model, the electroencephalogram signal can be quickly and accurately analyzed and processed, and the efficiency of car sickness state detection can be improved. The first electroencephalogram signal is input into the car sickness detection model in the embodiments of the present application, the car sickness detection model is used to determine whether the first user is in a car sickness state, and a car sickness detection result is output.

[0084] In order to improve the accuracy of car sickness state detection, in some embodiments, the above inputting the first electroencephalogram signal into the car sickness detection model to make the car sickness detection model output a car sickness detection result can include: inputting the first electroencephalogram signal and auxiliary detection data into the car sickness detection model to make the car sickness detection model output a car sickness detection result. Among them, the auxiliary detection data is used to assist the car sickness detection model to realize the detection of the car sickness state, and the auxiliary detection data can provide supplement for the first electroencephalogram signal, and multiple dimensions of data are combined to improve the accuracy of car sickness state detection.

[0085] The embodiments of the present application do not limit the specific content of the auxiliary detection data, and can be flexibly set according to the needs in actual application. In some embodiments, the auxiliary detection data includes at least one of the following: user physiological data, vehicle motion data, and vehicle environment data. The user physiological data includes, but is not limited to, electrocardiogram data, electrogastric data, and electrodermal data of the first user; the vehicle motion data includes, but is not limited to, the driving speed, acceleration, and yaw rate of the vehicle; and the vehicle environment data includes, but is not limited to, the temperature and air humidity inside and outside the vehicle. By integrating multi-dimensional and multi-modal data, the car sickness detection model can extract more rich semantic features, assist the car sickness detection model to make more accurate analysis and judgment, and effectively improve the accuracy of car sickness state detection.

[0086] The car sickness detection model can be in an end-to-end manner, and the real-time detection of the car sickness state can be realized by establishing a car sickness data set, training the car sickness detection model, and deploying the car sickness detection model. The car sickness data set can be constructed first, and the electroencephalogram signals of the first user or multiple users, user physiological data, vehicle motion data, vehicle environment data, and user subjective car sickness perception scores can be collected to construct training samples. Then, the car sickness detection model is trained based on the car sickness data set, so that the car sickness detection model can automatically predict the car sickness perception score of the user according to the input electroencephalogram signals, user physiological data, vehicle motion data, and vehicle environment data. The trained car sickness detection model is deployed in the vehicle, and the real-time collected first electroencephalogram signals and auxiliary detection data are input into the car sickness detection model, so that the car sickness detection model can predict whether the first user is in a car sickness state in real time. In addition, the car sickness detection model can predict the car sickness perception score of the first user by continuous prediction, which can not only predict whether the first user is in a car sickness state in real time, but also establish a car sickness state curve to master the dynamic fluctuation and change trend of the car sickness perception score, and predict the car sickness state of the first user in advance.

[0087] In some embodiments, the car sickness suppression operation includes at least one of the following: a visual suppression operation, an auditory suppression operation, a tactile suppression operation, a behavior guidance operation, and an electroencephalogram stimulation operation.

[0088] The currently widely accepted mechanism of motion sickness is the sensory conflict theory, which believes that the main cause of motion sickness is the difference between the signals transmitted to the cerebellum by the vestibular system, visual perception system and somatosensory system. The greater the difference, the more likely it is to cause motion sickness. According to the sensory conflict theory, the motion sickness suppression operation adopted by the embodiments of the present application includes visual suppression operation, auditory suppression operation, tactile suppression operation, behavior guidance operation, electroencephalogram stimulation operation, etc. Of course, the motion sickness suppression operation can also include other dimensional operations, such as olfactory suppression operation, etc. The embodiments of the present application timely execute the motion sickness suppression operation when the first user is in a motion sickness state, and the motion sickness suppression operation includes multi-dimensional suppression operation, which ensures that the motion sickness state of the first user can be effectively alleviated.

[0089] In some embodiments, the motion sickness suppression operation executed in step S100 includes: executing a first suppression operation; and in response to the first suppression operation being invalid, executing a second suppression operation. The motion sickness suppression operation includes the first suppression operation and the second suppression operation.

[0090] In the embodiments of the present application, the first suppression operation and the second suppression operation can be two different suppression operations of the same type, such as the first suppression operation and the second suppression operation are both visual suppression operations, but the visual content presented by the first suppression operation and the second suppression operation is different; or the first suppression operation and the second suppression operation can also be two different types of suppression operations, such as the first suppression operation is a visual suppression operation and the second suppression operation is a tactile suppression operation.

[0091] Since motion sickness has strong individual specificity, the causes of motion sickness are various, including genetics, psychological factors, physical state and vehicle environment, etc., so the corresponding effective motion sickness suppression operation is also different for different people. After the embodiments of the present application execute a certain suppression operation, whether the suppression operation is effective and the size of the effect can be judged by the change of the electroencephalogram signal, so as to make targeted adjustment and realize the individualization of the motion sickness suppression operation.

[0092] By timely replacing and taking the second suppression operation in the case that the first suppression operation is invalid, it can be ensured that the car sickness state of the first user can be relieved. In some embodiments, the first suppression operation is invalid in the case that the first user is still in the car sickness state after the first suppression operation is performed. For example, the first suppression operation is invalid in the case that the first user is still in the car sickness state after a certain time length after the first suppression operation is performed. In the embodiments of the present application, the first suppression operation being invalid includes the first suppression operation being completely invalid or being insufficiently valid. For example, the first suppression operation is completely invalid in the case that the car sickness state of the first user is not relieved or is aggravated after the first suppression operation is performed. Or, the first suppression operation is invalid in the case that the car sickness state of the first user is relieved but the relief degree is small after the first suppression operation is performed.

[0093] In some embodiments, the priority of the first suppression operation is higher than the priority of the second suppression operation. By selecting the currently performed suppression operation according to the priority order, it is helpful to avoid multiple attempts of different suppression operations without being invalid, and it is convenient to quickly relieve the car sickness state of the user.

[0094] In some embodiments, the priority of the first suppression operation is higher than the priority of the second suppression operation. By selecting the currently performed suppression operation according to the priority order, it is helpful to avoid multiple attempts of different suppression operations without being invalid, and it is convenient to quickly relieve the car sickness state of the user.

[0095] In order to improve the accuracy of the priority order so as to quickly relieve the car sickness state of the user, in some embodiments, the priority of the multiple suppression operations in the car sickness suppression operation is determined according to the validity of the multiple suppression operations in the car sickness suppression operation. In actual application, the validity of the multiple suppression operations can be counted, such as the number of times of replacement of the suppression operation, the difference between the car sickness state of the user before and after the execution of the suppression operation, etc., and then the priority of the multiple suppression operations is determined according to the validity of the multiple suppression operations. It should be understood that, since the reasons for the car sickness of different users can be different, the embodiments of the present application can establish different priority orders for different users. For example, the validity of the multiple suppression operations can be counted respectively for different users to establish the priority of the multiple suppression operations respectively. The priority of a certain suppression operation can be positively correlated with the validity of the suppression operation, that is, the higher the validity of the suppression operation is, the higher the priority of the suppression operation is, and when the first user is determined to be in the car sickness state, the suppression operation is more likely to be selected preferentially.
