Therefore, the features defined with "first", "second" can explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, the meaning of "multiple" is two or more.

[0066] Figure 1 A flowchart of a vehicle anti-car-sickness control method in an embodiment of the present application is shown, see Figure 1 A vehicle anti-car-sickness control method is provided, including at least S1 to S3, which are described in detail as follows:

[0067] In step S1, the jolt frequency and jolt direction of the vehicle are obtained. The jolt 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 including the vibration condition of road jolt, acceleration state, brake state and steering state, the vibration condition of road jolt including the jolt frequency and the jolt direction.

[0069] In step S2, it is detected whether the passengers in the vehicle have car-sickness.

[0070] In some embodiments, the detection of whether the passengers have car-sickness includes: obtaining a plurality of physiological indicators of the passengers in the vehicle; and if at least two indicators of the plurality of physiological indicators meet corresponding indicator conditions, it is determined that the passengers in the vehicle have car-sickness. By using a plurality of physiological indicators to determine whether the passengers in the vehicle have car-sickness, the detection accuracy is higher.

[0071] In some embodiments, the plurality of physiological indicators include passenger heart rate, passenger skin conductance, passenger respiratory rate, passenger body temperature, passenger eye movement image, and passenger facial expression.

[0072] In some embodiments, the passenger heart rate meets the corresponding indication condition when the passenger heart rate is greater than a preset heart rate. If the passenger feels uncomfortable or has car sickness symptoms, the heart rate will fluctuate, especially the heart rate can rapidly increase, i.e., the heartbeat accelerates. If the passenger heart rate is greater than the preset heart rate, it is determined that the passenger in the vehicle can have car sickness.

[0073] In some embodiments, the passenger heart rate is monitored in real time by a device such as a smart bracelet or a smart watch worn by the passenger in the vehicle.

[0074] In some embodiments, the passenger skin conductivity meets the corresponding indication condition when the passenger skin conductivity is greater than a preset skin conductivity. Electrodermal activity (EDA) is an indicator of human sweat gland activity. If the passenger in the vehicle is anxious, nervous or uncomfortable, the electrodermal activity will significantly increase, i.e., the skin conductivity will significantly increase. By monitoring the electrodermal activity of the passenger in the vehicle, it can be determined whether the passenger in the vehicle has physiological discomfort, and it can be inferred whether the passenger in the vehicle has car sickness. If the passenger skin conductivity is greater than the preset skin conductivity, it is determined that the passenger in the vehicle has physiological discomfort and can have car sickness.

[0075] In some embodiments, the passenger respiratory rate meets the corresponding indication condition when the passenger respiratory rate is greater than a preset heart rate or the passenger respiratory rate has a change rate greater than a preset change rate. When the passenger in the vehicle has car sickness, the breathing pattern will usually change, which can become rapid or irregular. If the passenger respiratory rate is greater than the preset heart rate or the passenger respiratory rate has a change rate greater than the preset change rate, i.e., the respiratory rate of the passenger in the vehicle abnormally fluctuates, it is determined that the passenger in the vehicle can have car sickness. The respiratory rate of the passenger in the vehicle can be detected by a sensor built in the vehicle.

[0076] In some embodiments, the passenger body temperature meets the corresponding indication condition when the passenger body temperature is greater than a preset body temperature. When the passenger in the vehicle has car sickness, the body temperature will slightly rise. If the passenger body temperature is greater than the preset body temperature, it is determined that the passenger in the vehicle can have car sickness.

[0077] In some embodiments, the passenger body temperature is monitored in real time by a smart device such as a smart bracelet or a smart watch worn by the passenger in the vehicle, or a temperature sensor in the vehicle, to determine whether the passenger in the vehicle has abnormal body temperature fluctuations.

[0078] In some embodiments, the passenger eye movement image meeting the corresponding indication condition is that the passenger heart rate meets a preset eye movement image. The preset eye movement image is an eye movement image when the passenger in the vehicle experiences car sickness. If the passenger in the vehicle experiences car sickness, the passenger may experience visual blurring, dizziness or eye movement incoordination. Through the visual monitoring system of the vehicle, combined with facial recognition technology, the eye movement changes of the passenger in the vehicle are analyzed. That is, the eye movement analysis technology is used to monitor the eye movement trajectory of the passenger in the vehicle, so as to effectively identify the visual response of the passenger, and on this basis, accurately judge whether the passenger in the vehicle experiences car sickness. The passenger eye movement image meeting the preset eye movement image indicates that the passenger in the vehicle may experience car sickness.

[0079] In some embodiments, the passenger facial expression meeting the corresponding indication condition is that the passenger facial expression meets a preset facial expression. The preset facial expression is a facial expression when the passenger in the vehicle experiences car sickness. When the passenger in the vehicle experiences discomfort, anxiety or car sickness, the facial expression may exhibit characteristics such as tension, frown and nausea. The facial expression of the passenger in the vehicle can be collected by the camera in the vehicle, combined with artificial intelligence and facial recognition technology, the facial expression of the passenger in the vehicle is analyzed in real time, whether the passenger facial expression meets the preset facial expression is judged, and whether the passenger in the vehicle experiences car sickness is judged.

[0080] In step S3, if the jolt frequency is less than the first frequency threshold or it is detected that the passenger in the vehicle experiences car sickness, 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 jolt direction, the direction of the vestibular perception of the passenger in the vehicle is the jolt direction, and the vehicle screen vibrates in the opposite direction of the vehicle at the same frequency, thereby creating a visual sense that the vehicle screen is stable near the original position, that is, the direction of the visual perception of the passenger in the vehicle is near the original position, which is similar to being stationary, so that the direction deviation between the vestibular perception and the visual perception of the passenger is reduced, and the feeling of car sickness of the passenger is alleviated.

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

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

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

[0085] In this way, while controlling the vehicle screen to vibrate in the same frequency as the vehicle, the vehicle is controlled to perform the target measure on the at least one vehicle device, so as to alleviate the feeling of car sickness of the passenger in multiple ways.

[0086] In some embodiments, the determining the target measure from the at least two preset measures according to the current display screen and the frequency of the jolt comprises: if the frequency of the jolt is greater than or equal to a second frequency threshold and less than a first frequency threshold, the target measure comprises displaying a logo image on the vehicle screen; and if the frequency of the jolt is greater than or equal to a third frequency threshold and less than the second frequency threshold, the target measure comprises 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; and if the display screen is a video playing screen, the target measure comprises stopping playing the video.

[0087] Displaying the logo image on the vehicle screen can attract the visual attention of the passenger in the vehicle, and reduce the visual effect difference of the brain in a visual deception manner, so as to alleviate the feeling of car sickness of the passenger in the vehicle or prevent the passenger in the vehicle from having car sickness. When the voice prompt is played, the attention of the passenger in the vehicle can be diverted to the hearing, so as to alleviate the feeling of car sickness of the passenger in the vehicle. The voice prompt can be the current jolt condition and other important driving information, such as current road condition, driving safety prompt, and navigation information update. The current road condition can be "Please pay attention to the jolt ahead", the driving safety prompt can be "Please keep a safe distance", and the navigation information update can be "Turn right in 100 meters ahead".

[0088] In the present application, the jolt frequency greater than or equal to the second frequency threshold and less than the first frequency threshold can be understood as the jolt frequency being a medium-frequency jolt frequency, such as 2-6 Hz, mainly caused by small uneven road surfaces, such as fine cracks or small stone road surfaces, at this time, the passengers in the vehicle feel more obvious, and the possibility of causing discomfort is high, and the probability of car sickness is higher than that when the vehicle is in a medium-frequency jolt frequency. The jolt frequency greater than or equal to the third frequency threshold and less than the second frequency threshold can be understood as the jolt frequency being a low-frequency jolt frequency, such as 0.5-2 Hz, mainly caused by large uneven road surfaces, such as potholes and bumps, 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 obvious, the possibility of causing discomfort is higher, and the probability of car sickness is higher than that when the vehicle is in a medium-frequency jolt frequency. The jolt frequency greater than the first frequency threshold can be understood as the jolt frequency being a high-frequency jolt frequency, such as 6-20 Hz, 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 parts of the vehicle and affect the driving safety, at this time, the passengers in the vehicle do not feel obvious, and it is not easy to cause discomfort.

[0089] It can be understood that the jolt frequency that the passengers in the vehicle can perceive is a medium-frequency jolt frequency and a low-frequency jolt frequency, and the present application controls the vehicle screen to vibrate for the medium-frequency jolt frequency and the low-frequency jolt frequency.

[0090] Exemplarily, the vehicle screen is an entertainment system screen, the entertainment system screen is playing a video, the first frequency threshold is 6 Hz, the second frequency threshold is 2 Hz, the jolt frequency is 5 Hz, and the logo image is an arrow. The entertainment system screen is controlled to vibrate in reverse at 5 Hz, such as vibrating downward when the jolt direction is upward, and at the same time, the vehicle screen is controlled to display an arrow with the same frequency as the jolt frequency, attracting the visual attention of the passengers in the vehicle.

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

[0092] Exemplarily, the vehicle-mounted screen is an entertainment system screen, the current display picture is a video playing picture, the second frequency threshold is 2 Hz, the third frequency threshold is 0.5 Hz, and the jolt frequency is 1 Hz. The passengers in the vehicle are obviously sensitive to the low-frequency jolt frequency, and it is not recommended for the passengers in the vehicle to continue watching the video. The vehicle-mounted screen is controlled to stop playing the video, that is, the video playing is automatically paused, and a voice prompt “the current video has been paused playing” is played. The logic of controlling the vehicle-mounted screen to stop playing the video needs to be integrated into the vehicle-mounted entertainment system.

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

[0094] Exemplarily, the current display picture is a navigation picture, the first frequency threshold is 6 Hz, the second frequency threshold is 2 Hz, and the jolt frequency is 5 Hz. At this time, the target measure does not include displaying a logo image on the vehicle-mounted screen, that is, the navigation picture is not allowed to be blocked, and the entertainment system screen is controlled to vibrate in reverse at 5 Hz, for example, vibrating downward when the jolt direction is upward, and the logo image is not displayed on the vehicle-mounted screen.

[0095] In some embodiments, the target measure is determined from the at least two preset measures according to the current display picture 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 the voice prompt and folding the target screen.

[0096] Exemplarily, the target screen is a rear-row sunroof screen, the second frequency threshold is 2 Hz, the third frequency threshold is 0.5 Hz, and the jolt frequency is 1 Hz. The passengers in the vehicle are obviously sensitive to the low-frequency jolt frequency. Folding the rear-row sunroof screen can divert the visual attention of the passengers in the vehicle and avoid the passengers in the vehicle from bumping into the rear-row sunroof screen. At the same time, before folding the rear-row sunroof screen, a voice prompt “the rear-row entertainment screen will be automatically folded. Please pay attention to safety” is played. The rear-row entertainment screen in the voice prompt is the rear-row sunroof screen.

[0097] In some embodiments, the logo image can be fluctuating, rotating or rhythmically changing to simulate the swaying inside the vehicle, at which time the passengers inside the vehicle view the logo image with dynamic vision to help the brain recalibrate perception to be more consistent with the actual motion experience.

[0098] In some embodiments, further comprising: controlling the logo image displayed on the in-vehicle screen to move in the jolting direction. The logo image moving display can better attract the attention of the passengers inside the vehicle, thereby alleviating the feeling of car sickness of the passengers inside the vehicle.

[0099] In some embodiments, further comprising: controlling the logo image displayed on the in-vehicle screen to move in the jolting direction according to the jolting frequency, so that the logo image is synchronized with the motion frequency of the vehicle, and the passengers inside the vehicle adapt to the changing vehicle environment visually.

[0100] In some embodiments, further comprising: obtaining historical viewing data of the passengers inside the vehicle on the in-vehicle screen; determining viewing preferences of the passengers inside the vehicle according to the historical viewing data, the viewing preferences including at least one of image color preference, image size preference and image shape preference; and setting at least one of size, shape and color of the logo image according to the viewing preferences. The logo image and the viewing preferences match, which can better attract the attention of the passengers inside the vehicle, thereby more effectively alleviating the feeling of car sickness of the passengers inside the vehicle.

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

[0102] In some embodiments, the logo image is an image with a contrast higher than a preset contrast, i.e. a high-contrast image, so that the passengers inside the vehicle can quickly focus on the logo image to distract their attention from car sickness.

[0103] In some embodiments, the method further comprises: if the jolting frequency is less than a first frequency threshold or car sickness of the passengers is detected, controlling the in-vehicle foldable screen to change the folding state or vibrate in the opposite direction of the jolting direction according to the jolting frequency. The in-vehicle foldable screen has two folding states of unfolding and folding, and the in-vehicle foldable screen can be a rear overhead screen. When the in-vehicle foldable screen has two folding states of unfolding and folding, either the in-vehicle foldable screen is controlled to vibrate in the opposite direction or the in-vehicle foldable screen is controlled to change the folding state, such as from the unfolding state to the folding state.

[0104] In some embodiments, further comprising: obtaining a vibration amplitude of the vehicle; and controlling the vehicle screen to vibrate in the opposite direction of the bumping direction according to the vibration amplitude, so that the visual perception direction of the passengers in the vehicle is as close to the original position as possible, and the stability of the visual perception direction is maintained.

[0105] In some embodiments, the vehicle screen is controlled to vibrate in the opposite direction of the bumping direction according to the bumping frequency by a reverse vibration algorithm.

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

[0107] In this application, when the bumping frequency is low, the passengers may experience car sickness. If the bumping frequency is less than a first frequency threshold or it is detected that the passengers in the vehicle experience car sickness, on the one hand, the vehicle screen is controlled to vibrate in the opposite direction of the bumping direction according to the bumping frequency, the vehicle screen and the vehicle maintain the same frequency of reverse vibration, so that the direction deviation between the vestibular perception and the visual perception of the passengers is reduced, and the feeling of car sickness of the passengers is alleviated. On the other hand, a voice prompt is played to attract the attention of the passengers in the vehicle from the auditory sense, or a logo image is displayed to attract the attention of the passengers in the vehicle from the visual sense, further alleviating the feeling of car sickness of the passengers.
