Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the feature.

[0066] Figure 1 A flow chart of a vehicle motion sickness prevention control method in an embodiment of the present application is shown, see Figure 1 , a vehicle motion sickness prevention control method is provided, which includes at least S1 to S3, which are described in detail as follows:

[0067] In step S1, the bumping frequency and bumping direction of the vehicle are obtained. The bumping direction can be upward, downward, left or right.

[0068] In some embodiments, the external environment of the vehicle is detected by a camera, and the dynamic information of the vehicle is detected by an accelerometer and a gyroscope. The dynamic information of the vehicle includes the vibration condition of road bumps, acceleration status, braking status and steering status. The vibration condition of road bumps includes the bump frequency and the bump direction.

[0069] In step S2, it is detected whether a passenger in the vehicle suffers from motion sickness.

[0070] In some embodiments, the detecting whether the passenger suffers from motion sickness includes: obtaining multiple physiological indicators of the passenger in the vehicle; and determining that the passenger in the vehicle suffers from motion sickness if at least two of the multiple physiological indicators meet corresponding indicator conditions. Determining whether the passenger in the vehicle suffers from motion sickness by using multiple physiological indicators has high detection accuracy.

[0071] In some embodiments, the multiple physiological indicators include passenger heart rate, passenger skin conductivity, passenger breathing rate, passenger body temperature, passenger eye movement images, and passenger facial expressions.

[0072] In some embodiments, the passenger's heart rate meets the corresponding indication condition when the passenger's heart rate is greater than a preset heart rate. If the passenger feels uncomfortable or has motion sickness symptoms, the heart rate will fluctuate, and in particular, the heart rate may rise rapidly, that is, the heartbeat accelerates. If the passenger's heart rate is greater than the preset heart rate, it is determined that the passenger in the vehicle may suffer from motion sickness.

[0073] In some embodiments, the heart rate changes of the passengers in the vehicle are monitored in real time through devices such as smart bracelets or smart watches worn by the passengers in the vehicle.

[0074] In some embodiments, the passenger skin conductivity meets the corresponding indication condition that the passenger skin conductivity is greater than a preset conductivity. The galvanic skin response (EDA) is an indicator of the activity of human sweat glands. If the passenger in the vehicle is anxious, nervous or uncomfortable, the galvanic skin response will increase significantly, that is, the skin conductivity will increase significantly. By monitoring the galvanic skin response of the passenger in the vehicle, it can be determined whether the passenger in the vehicle has physiological discomfort, and then it can be inferred whether the passenger in the vehicle has motion sickness. If the passenger skin conductivity is greater than the preset conductivity, it can be determined that the passenger in the vehicle has physiological discomfort and may have motion sickness.

[0075] In some embodiments, the passenger's respiratory frequency meets the corresponding indication condition that the passenger's respiratory frequency is greater than a preset heart rate or the rate of change of the passenger's respiratory frequency is greater than a preset rate of change. When a passenger in the vehicle is motion sick, the breathing pattern usually changes and may become rapid or irregular. If the passenger's respiratory frequency is greater than a preset heart rate or the rate of change of the passenger's respiratory frequency is greater than a preset rate of change, that is, the respiratory frequency of the passenger in the vehicle fluctuates abnormally, it is determined that the passenger in the vehicle may be motion sick. The respiratory frequency of the passenger in the vehicle can be detected by a sensor built into the vehicle.

[0076] In some embodiments, the passenger's body temperature meets the corresponding indication condition when the passenger's body temperature is greater than a preset body temperature. When the passenger in the vehicle experiences motion sickness, the body temperature will rise slightly. When the passenger's body temperature is greater than the preset body temperature, it is determined that the passenger in the vehicle may experience motion sickness.

[0077] In some embodiments, the body temperature changes of the passengers in the vehicle are monitored in real time through smart devices such as smart bracelets or smart watches worn by the passengers in the vehicle, or temperature sensors in the vehicle, to determine whether the passengers in the vehicle have abnormal body temperature fluctuations.

[0078] In some embodiments, the passenger eye movement image meets the corresponding indication condition that the passenger heart rate meets the preset eye movement image. The preset eye movement image is the eye movement image when the passenger in the vehicle is experiencing motion sickness. If the passenger in the vehicle is experiencing motion sickness, he or she may experience blurred vision, dizziness, or incoordination of eye movements. The eye movement changes of the passengers in the vehicle are analyzed through the visual monitoring system of the vehicle in combination with facial recognition technology. That is, the eye movement analysis technology is used to monitor the eye movement trajectories of the passengers in the vehicle, so as to effectively identify the visual reactions of the passengers, and on this basis, accurately determine whether the passengers in the vehicle are experiencing motion sickness. The passenger eye movement image meets the preset eye movement image, indicating that the passenger in the vehicle may be experiencing motion sickness.

[0079] In some embodiments, the passenger's facial expression meets the corresponding indication condition when the passenger's facial expression meets a preset facial expression. The preset facial expression is the facial expression of the passenger in the vehicle when motion sickness occurs. When the passenger in the vehicle experiences discomfort, anxiety or motion sickness, the facial expression may show characteristics such as tension, frowning and nausea. The facial expression of the passenger in the vehicle can be collected by the camera in the vehicle, and the facial expression of the passenger in the vehicle can be analyzed in real time by combining artificial intelligence and facial recognition technology to determine whether the passenger's facial expression meets the preset facial expression, thereby determining whether the passenger in the vehicle experiences motion sickness.

[0080] In step S3, if the jolt frequency is less than a first frequency threshold or motion sickness is detected in the vehicle passenger, the vehicle screen is controlled to vibrate in the opposite direction of the jolt direction according to the jolt frequency.

[0081] In this way, when the vehicle moves in the direction of the bump, the direction of the vestibular perception of the passengers in the vehicle is the direction of the bump, and the on-board screen and the vehicle maintain opposite vibrations at the same frequency, thereby visually creating a feeling that the on-board screen is stable near the original position, that is, the direction of the visual perception of the passengers in the vehicle is near the original position, which is close to being motionless, thereby reducing the directional deviation between the passengers' vestibular perception and visual perception, and alleviating the passengers' feeling of motion sickness.

[0082] In addition, the vehicle-mounted screen is controlled to vibrate in the opposite direction instead of remaining motionless, so that the control of the vehicle-mounted screen is more flexible.

[0083] It should be noted that in the prior art, when the vehicle moves in the direction of the bump, the direction of the vestibular perception of the passengers in the vehicle is the direction of the bump, and the direction of the visual perception of the passengers in the vehicle is the opposite direction of the bump, and the directional deviation between the two is greater than the directional deviation between the vestibular perception and visual perception of the passengers in the present application.

[0084] In some embodiments, the method further includes: obtaining the current display screen of the vehicle screen; if the jolt frequency is less than the first frequency threshold or motion sickness of the passenger in the vehicle is detected, determining a target measure from the at least two preset measures according to the current display screen and the jolt frequency; and controlling the vehicle to execute the target measure for at least one vehicle device to change the state of the at least one vehicle device. Controlling the vehicle to execute the target measure for at least one vehicle device can alleviate the passenger's feeling of motion sickness. The vehicle device can be the vehicle screen or the vehicle audio system.

[0085] In this way, while controlling the vehicle-mounted screen to maintain reverse vibration at the same frequency as the vehicle, the vehicle is controlled to execute target measures for at least one vehicle-mounted device, thereby alleviating the passenger's feeling of motion sickness in a variety of ways.

[0086] In some embodiments, the target measure is determined from the at least two preset measures based on the current display screen and the bump frequency, including: if the bump frequency is greater than or equal to the second frequency threshold and less than the first frequency threshold, the target measure includes displaying a logo image on the vehicle-mounted screen; if the bump frequency is greater than or equal to the third frequency threshold and less than the second frequency threshold, the target measure includes playing a voice prompt, wherein the first frequency threshold is greater than the second frequency threshold, and the second frequency threshold is greater than the third frequency threshold; if the display screen is a video playback screen, the target measure includes stopping playing the video.

[0087] Displaying the logo image on the vehicle screen can attract the visual attention of the passengers in the vehicle, reduce the poor visual effect of the brain in a visual deception way, alleviate the feeling of motion sickness of the passengers in the vehicle or prevent the passengers in the vehicle from experiencing motion sickness. When playing the voice prompt, the attention of the passengers in the vehicle can be diverted to the hearing, alleviating the feeling of motion sickness of the passengers in the vehicle. The voice prompt can be the current road bumps and other important driving information, such as the current road conditions, driving safety tips and navigation information updates, among which the current road conditions can be "the road ahead is bumpy, please pay attention", the driving safety prompt can be "please keep a safe distance", and the navigation information update can be "turn right 100 meters ahead".

[0088] In the present application, the jolt frequency is greater than or equal to the second frequency threshold and less than the first frequency threshold, which can be understood as the jolt frequency being a medium-frequency jolt frequency, such as 2-6 Hz, which is mainly caused by smaller uneven roads, such as roads with fine cracks or small stones. At this time, the passengers in the vehicle feel it more obviously and may cause discomfort. The jolt frequency is greater than or equal to the third frequency threshold and less than the second frequency threshold, which can be understood as the jolt frequency being a low-frequency jolt frequency, such as 0.5-2 Hz, which is mainly caused by large-scale uneven roads, such as potholes and raised roads. At this time, the vehicle will shake as a whole, affecting the comfort and safety of the passengers in the vehicle. The passengers in the vehicle feel it obviously, and the possibility of causing discomfort is higher. The probability of motion sickness is higher than when the vehicle is in the medium-frequency jolt frequency period. The bump frequency is greater than the first frequency threshold, which can be understood as a high-frequency bump frequency, such as 6-20 Hz, which is mainly caused by the interaction between the tire and the ground, such as local vibration of the tire, which may cause wear and fatigue of the vehicle components and affect driving safety. At this time, the passengers in the vehicle do not feel it obviously and it is not easy to cause discomfort.

[0089] It can be understood that the vibration frequencies that can be felt by passengers in the vehicle are medium-frequency vibration frequencies and low-frequency vibration frequencies. The present application controls the vibration of the vehicle-mounted screen with respect to the medium-frequency vibration frequencies and low-frequency vibration frequencies.

[0090] Exemplarily, the in-vehicle screen is an entertainment system screen that is playing a video, the first frequency threshold is 6 Hz, the second frequency threshold is 2 Hz, the bump frequency is 5 Hz, and the logo image is an arrow. The entertainment system screen is controlled to vibrate in the opposite direction of 5 Hz, for example, it vibrates downward when the bump direction is upward. At the same time, the in-vehicle screen is controlled to display an arrow with the same frequency as the bump frequency to attract the visual attention of passengers in the vehicle.

[0091] In some embodiments, the target measure is determined from the at least two preset measures based on the current display screen and the jolt frequency, including: if the jolt frequency is greater than or equal to a third frequency threshold and less than a second frequency threshold, and the current display screen is a video playback screen, the target measure includes stopping the video playback and the playback voice prompt.

[0092] Exemplarily, the in-vehicle screen is an entertainment system screen, the currently displayed screen is a video playback screen, the second frequency threshold is 2 Hz, the third frequency threshold is 0.5 Hz, the bump frequency is 1 Hz, and the passengers in the vehicle are obviously aware of the low-frequency bump frequency. It is not recommended that the passengers in the vehicle continue to watch the video. The in-vehicle screen is controlled to stop playing the video, that is, the video playback is automatically paused, and a voice prompt "The current video has been paused" is played. The logic for controlling the in-vehicle screen to stop playing the video needs to be integrated into the in-vehicle entertainment system.

[0093] In some embodiments, the determining of the target measure from the at least two preset measures according to the current display screen and the bump frequency includes: if the current display screen is an instrument screen, a navigation screen, an intelligent driving screen, or a reversing image screen, the target measure does not include displaying a logo image on the vehicle screen. When the current display screen is an instrument screen, a navigation screen, an intelligent driving screen, or a reversing image screen, displaying a logo image on the vehicle screen will block the current display screen and affect the normal use of the vehicle. Therefore, the target measure does not include displaying a logo image on the vehicle screen.

[0094] Exemplarily, the currently displayed screen is a navigation screen, the first frequency threshold is 6 Hz, the second frequency threshold is 2 Hz, and the bump frequency is 5 Hz. At this time, the target measures do not include displaying a logo image on the vehicle screen, that is, blocking the navigation screen is not allowed, and the entertainment system screen is controlled to vibrate in the opposite direction at 5 Hz, for example, vibrating downward when the bump direction is upward, and the logo image is not displayed on the vehicle screen.

[0095] In some embodiments, the target measure is determined from the at least two preset measures based on the current display screen and the jolt frequency, including: if the jolt frequency is greater than or equal to a third frequency threshold and less than a second frequency threshold, the target measure includes playing the voice prompt and folding the target screen.

[0096] Exemplarily, the target screen is the rear ceiling screen, the second frequency threshold is 2 Hz, the third frequency threshold is 0.5 Hz, the bump frequency is 1 Hz, and the passengers in the vehicle are obviously aware of the low-frequency bump frequency. Folding the rear ceiling screen can divert the visual attention of the passengers in the vehicle and prevent the passengers in the vehicle from bumping into the rear ceiling screen. At the same time, before folding the rear ceiling screen, a voice prompt is played, "The rear entertainment screen will be folded automatically, please pay attention to safety." The rear entertainment screen in the voice prompt is the rear ceiling screen.

[0097] In some embodiments, the logo image may be waving, rotating, or rhythmically changing to simulate shaking within the vehicle. At this time, passengers in the vehicle view the logo image with dynamic vision, thereby helping the brain to recalibrate perception to make it more consistent with actual motion experience.

[0098] In some embodiments, the method further includes: controlling the sign image displayed on the vehicle screen to move toward the bumpy direction. The moving sign image can better attract the attention of the passengers in the vehicle, thereby alleviating the feeling of motion sickness of the passengers in the vehicle.

[0099] In some embodiments, it also includes: controlling the logo image displayed on the vehicle screen to move in the bump direction according to the bump frequency, so that the logo image is synchronized with the movement frequency of the vehicle, and the vision of the passengers in the vehicle adapts to the constantly changing vehicle environment.

[0100] In some embodiments, the method further includes: obtaining historical viewing data of the vehicle screen by the vehicle passengers; determining the viewing preferences of the vehicle passengers according to the historical viewing data, wherein the viewing preferences include at least one of image color preference, image size preference, and image shape preference; and setting at least one of the size, shape, and color of the logo image according to the viewing preferences. The logo image matches the viewing preferences, which can better attract the attention of the vehicle passengers, thereby more effectively alleviating the feeling of motion sickness of the vehicle passengers.

[0101] In some embodiments, determining the viewing preferences of the passengers in the vehicle based on the historical viewing data includes: training a pre-established machine learning model based on the historical viewing data to determine the viewing preferences.

[0102] In some embodiments, the sign image is an image with a contrast higher than a preset contrast, that is, the sign image is a high-contrast image, so that the passengers in the vehicle can quickly focus on the sign image, distracting the passengers in the vehicle from motion sickness.

[0103] In some embodiments, the method further includes: if the turbulence frequency is less than a first frequency threshold or motion sickness of a passenger is detected, controlling the vehicle-mounted foldable screen to change its retracted state or vibrate in the opposite direction of the turbulence direction according to the turbulence frequency. The vehicle-mounted foldable screen has two retractable states, namely, unfolded and folded, and the vehicle-mounted foldable screen may be a rear-row ceiling screen. When the vehicle-mounted foldable screen has two retractable states, namely, unfolded and folded, either the vehicle-mounted foldable screen is controlled to vibrate in the opposite direction, or the vehicle-mounted foldable screen is controlled to change its retracted state, such as from an unfolded state to a folded state.

[0104] In some embodiments, it also includes: obtaining the vibration amplitude of the vehicle; and according to the vibration amplitude, controlling the vehicle-mounted screen to vibrate in the opposite direction of the bumpy direction, so that the direction of visual perception of the passengers in the vehicle is as close to stationary as possible, maintaining the stability of the direction of visual perception.

[0105] In some implementations, the vehicle-mounted screen is controlled to vibrate in a direction opposite to the shaking direction according to the shaking frequency through a reverse vibration algorithm.

[0106] In some implementations, historical vibration data of the vehicle-mounted screen is obtained, a pre-established machine learning model is trained based on the historical vibration data, and the reverse vibration algorithm is optimized.

[0107] In the present application, when the bump frequency is low, passengers may experience motion sickness. If the bump frequency is less than the first frequency threshold or it is detected that the passengers in the vehicle experience motion sickness, that is, when the passengers experience motion sickness, on the one hand, the vehicle's on-board screen is controlled to vibrate in the opposite direction of the bump direction according to the bump frequency, and the on-board screen and the vehicle maintain the same frequency of reverse vibration, so that the directional deviation of the passenger's vestibular perception and visual perception is reduced, thereby alleviating the passenger's feeling of motion sickness. On the other hand, voice prompts are played to attract the attention of the passengers in the vehicle auditorily, or sign images are displayed to attract the attention of the passengers in the vehicle visually, thereby further alleviating the passenger's feeling of motion sickness.
