Anti-motion sickness method, device and vehicle

[0001] This application claims priority to the Chinese patent application with application number 202311633522.0 filed with the State Intellectual Property Office of China on November 30, 2023, and priority to the Chinese patent application with the invention name “Anti-motion sickness method, device and vehicle”, all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of smart cars, and more particularly, to an anti-motion sickness method, device and vehicle. Background Art

[0003] Motion sickness is a common physiological phenomenon. When a user experiences motion sickness, they are prone to symptoms such as dizziness, nausea, or vomiting, which can seriously affect their physical and mental health and driving safety. With the development of electric vehicles, their enhanced recovery and acceleration capabilities make them more susceptible to motion sickness. Therefore, how to alleviate users' motion sickness symptoms has become an urgent problem. Summary of the Invention

[0004] The present application provides an anti-motion sickness method, device and vehicle, which help alleviate the user's motion sickness symptoms, thereby helping to improve the user's driving experience.

[0005] In a first aspect, a motion sickness prevention method is provided, the method comprising: obtaining motion information of a vehicle, road condition information, and physiological characteristic information of a user; and controlling an anti-motion sickness device in the vehicle to perform corresponding operations based on the motion information, the road condition information, and the physiological characteristic information.

[0006] Based on this technical solution, multi-dimensional data (motion information, road condition information, and physiological characteristics) can be detected while the vehicle is in motion, and the anti-motion sickness equipment in the vehicle can be controlled based on this multi-dimensional data to perform corresponding operations. This can more accurately identify the user's motion sickness level and the degree of their need for motion sickness relief, helping to timely alleviate the user's motion sickness symptoms and thus improve the user's driving experience.

[0007] In some possible implementations, the motion information includes one or more of data collected by the vehicle's acceleration sensor, seat pressure, data collected by a speed sensor, a pedal signal, a steering wheel angle, and an angular velocity.

[0008] In some possible implementations, the data collected by the acceleration sensor may include an acceleration signal of an air suspension system, or an acceleration signal of an electronic stability control (ESC).

[0009] In some possible implementations, the motion information includes a motion sickness dose value (MSDV). For example, the vehicle may determine the MSDV based on data collected by an acceleration sensor.

[0010] In some possible implementations, physiological characteristic information includes one or more of the following: information indicating the degree of motion sickness, such as the user's heart rate, blood oxygen level, and electroencephalogram (EEG), information about the user's facial features, or voice information. For example, the facial features information may include yawning, nausea, vomiting, eye movements, and other sensory information. Another example is that the voice information may include motion sickness keywords, such as "I feel a little dizzy."

[0011] In some possible implementations, obtaining physiological characteristic information includes: obtaining physiological characteristic information sent by a wearable device.

[0012] In some possible implementations, obtaining the physiological characteristic information includes: determining the physiological characteristic information based on data collected by in-cabin sensors, where the in-cabin sensors include one or more of an in-cabin camera, a radar, and a microphone.

[0013] In some possible implementations, the road condition information may include information about the road section the vehicle is currently on, such as the location and type of the road section the vehicle is currently on.

[0014] In some possible implementations, obtaining road condition information includes determining the road condition information based on data collected by external sensors, or determining the road condition information based on navigation information. For example, the external sensors include external cameras, radar, and the like.

[0015] In some possible implementations, obtaining road condition information includes: determining the road condition information based on navigation information.

[0016] In combination with the first aspect, in certain implementations of the first aspect, the anti-motion sickness device includes multiple devices, and the anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information, and the physiological characteristic information, including: controlling at least some of the multiple devices to perform corresponding operations based on the situation that preset conditions are met in the motion information, the road condition information, and the physiological characteristic information.

[0017] Based on this technical solution, the vehicle can control different devices to perform motion sickness prevention operations in different scenarios. This, through device-by-device control, can make the operations performed by the motion sickness prevention devices more suitable for the user's current situation, helping to improve the vehicle's intelligence and thus enhance the user's driving experience.

[0018] In some possible implementations, the preset conditions include preset conditions for operation information, preset conditions for road condition information, and preset conditions for physiological characteristic information.

[0019] For example, the preset conditions for running information include but are not limited to at least one of the following: the voice information sent by the user includes motion sickness keywords; or, the user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude; or, the user's heart rate variability time domain index becomes smaller and the variation amplitude is greater than or equal to the first preset amplitude; or, the user's heart rate variability low-frequency component increases and the increase amplitude is greater than or equal to a third preset amplitude; or, the user's heart rate variability high-frequency component decreases and the decrease amplitude is greater than or equal to a fourth preset amplitude; or, the user yawns, feels nauseous, or vomits.

[0020] For another example, the preset conditions for the road condition information include but are not limited to at least one of the following: the vehicle is on a continuous bend; the vehicle is on a damaged road or a road under construction.

[0021] For another example, the preset conditions for physiological characteristic information include but are not limited to at least one of the following: the number of times the vehicle experiences sudden acceleration, sudden deceleration, or sudden turn within a preset time period is greater than or equal to a preset number; the MSDV is greater than or equal to a preset threshold.

[0022] In combination with the first aspect, in certain implementations of the first aspect, the multiple devices include a body control device, a display device, and an occupant environment device, and based on the situation where the motion information, the road condition information, and the physiological characteristic information meet preset conditions, at least some of the multiple devices are controlled to perform corresponding operations, including: when the physiological characteristic information meets the preset conditions, controlling the body control device, the display device, and the occupant environment device to perform corresponding operations.

[0023] Based on the above technical solution, physiological characteristic information can be set to have the highest priority. When the physiological characteristic information meets the preset conditions, the body control device, the display device, and the passenger environment device can be directly controlled to perform the corresponding anti-motion sickness operation without further detection of other data. In this way, when the user has obvious motion sickness symptoms (for example, voice information and facial features indicate that the user is motion sick), multiple devices can be immediately controlled to perform response operations, which helps to ensure that the user's motion sickness symptoms are relieved in a timely manner, thereby helping to improve the user's driving experience.

[0024] In some possible implementations, the preset conditions of the different physiological characteristic information may correspond to different priorities.

[0025] For example, the priority of the preset condition that the user's voice message includes a key word for motion sickness is high. Another example is that the user yawns, feels nauseous, or vomits, and the priority is medium. Another example is that the user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude, and the priority is low.

[0026] When physiological characteristic information meets different preset conditions, different devices can be controlled to perform corresponding anti-motion sickness operations. For example, if the user's voice information contains motion sickness keywords, the body control device, the display device, and the passenger environment device can be controlled to perform corresponding operations. For another example, if the user is detected to be yawning, nausea, vomiting, etc., the body control device and the passenger environment device can be controlled to perform corresponding operations. For another example, if the user's heart rate fluctuation amplitude is detected to be greater than or equal to a first preset amplitude, the passenger environment device can be controlled to perform corresponding operations.

[0027] In combination with the first aspect, in certain implementations of the first aspect, the multiple devices include a body control device, a display device, and an occupant environment device, and based on the situation where the motion information, the road condition information, and the physiological characteristic information meet the preset conditions, at least some of the multiple devices are controlled to perform corresponding operations, including: when the motion information meets the preset conditions and the physiological characteristic information does not meet the preset conditions, controlling the body control device to perform corresponding operations.

[0028] Based on the above technical solution, when motion information is detected to meet preset conditions but physiological characteristic information does not, the vehicle body control device can be controlled to perform anti-motion sickness operations. This allows the vehicle body control device to perform appropriate operations when the vehicle's motion information may cause motion sickness in the user, but the user has not yet clearly shown signs of motion sickness. This minimizes disturbance to the user, preventing motion sickness and improving the user's driving experience.

[0029] In some possible implementations, controlling the body control device to perform corresponding operations includes at least one of the following: controlling the vehicle's acceleration mode to an economic mode, controlling the energy recovery intensity to decrease, controlling the vehicle body height to decrease, or controlling the comfort braking mode to turn on.

[0030] In combination with the first aspect, in some implementations of the first aspect, the user is located in a first area in the vehicle, and the at least part of the device is associated with the first area.

[0031] Based on the above technical solution, the vehicle can control the anti-motion sickness equipment in the area where the user is located to perform anti-motion sickness operations. In this way, the motion sickness symptoms of users in the corresponding area can be alleviated, which helps to improve the user's driving experience.

[0032] In some possible implementations, the user is located in a first area in a vehicle, and based on the motion information, the road condition information, and the physiological characteristic information, the anti-motion sickness equipment in the vehicle is controlled to perform corresponding operations, including: when the user's physiological characteristic information meets preset conditions, controlling the display device and the passenger environment equipment in the first area to perform corresponding anti-motion sickness operations.

[0033] In some possible implementations, the display device and the passenger environment equipment in the first area are controlled to perform corresponding anti-motion sickness operations, including: controlling the windows in the first area to open, controlling the operating mode of the air conditioner in the first area to adjust to the face-blowing mode, controlling the fragrance in the first area to turn on, controlling the display parameters of the display device in the first area, or controlling at least one of the air purification device in the first area to turn on.

[0034] In some possible implementations, a vehicle cabin includes multiple users, including a first user and a second user, the first user is located in a first area, and the second user is located in a second area. According to the motion information, the road condition information, and the physiological characteristic information, the anti-motion sickness device in the vehicle is controlled to perform corresponding operations, including: when the physiological characteristic information of the first user meets a preset condition and the physiological characteristic information of the second user does not meet the preset condition, the anti-motion sickness device in the first area is controlled to perform an aggressive anti-motion sickness operation and the anti-motion sickness device in the second area is controlled to perform a soothing anti-motion sickness operation.

[0035] Exemplarily, the first user is located in the left area of ​​the second row and the second user is located in the right area of ​​the second row. Before the anti-motion sickness operation is performed, the windows of the left area of ​​the second row and the right area of ​​the second row are closed and the brightness of their display screens is 100%. The anti-motion sickness device in the first area is controlled to perform an aggressive anti-motion sickness operation, including: opening the windows of the left area of ​​the second row to 50% and controlling the brightness of the display screens of the left area of ​​the second row to be lowered to 50%; and the anti-motion sickness device in the second area is controlled to perform a soothing anti-motion sickness operation, including: opening the windows of the right area of ​​the second row to 90% and controlling the brightness of the display screens of the right area of ​​the second row to be lowered to 70%.

[0036] In combination with the first aspect, in certain implementations of the first aspect, based on the situation where the motion information, the road condition information, and the physiological characteristic information meet the preset conditions, at least some of the multiple devices are controlled to perform corresponding operations, including: when at least some of the information among the motion information, the road condition information, and the physiological characteristic information meet the preset conditions, controlling the prompt device to prompt the user to turn on at least some of the devices; and controlling at least some of the devices to turn on based on the user's first input, the first input indicating to turn on at least some of the devices.

[0037] Based on the above technical solution, the prompt device prompts the user to turn on the anti-motion sickness device, and the user does not need to actively turn on the anti-motion sickness device, which helps to avoid tedious operations for the user and thus helps to improve the user's driving experience.

[0038] In combination with the first aspect, in certain implementations of the first aspect, the road condition information includes location information, which indicates that the anti-motion sickness device was turned on when the vehicle passed the first road section before. The anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information, including: before the road condition information indicates that the vehicle passes the first road section again, the prompt device is controlled to prompt the user to turn on the anti-motion sickness device.

[0039] Based on the above technical solution, road condition information can include a correspondence between road sections and whether the anti-motion sickness device is enabled on that road section. If the vehicle detects that the user has activated the anti-motion sickness device when passing through a first road section, the vehicle can proactively prompt the user to activate the anti-motion sickness device before the vehicle passes through the first road section again. This saves the user from having to proactively activate the anti-motion sickness device, helping to avoid tedious user operations and thus improving the user's driving experience.

[0040] In some possible implementations, the road condition information may further include a correspondence between a road section and a type of anti-motion sickness device activated by the user on the road section.

[0041] For example, the road condition information may further include a correspondence between the road section 1 and the vehicle body control device; and a correspondence between the road section 2 and the vehicle body control device and the display device.

[0042] In combination with the first aspect, in certain implementations of the first aspect, the road condition information includes road surface information, which indicates that the anti-motion sickness device was turned on when the vehicle passed through a first type of road section before. The anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information, including: before the road condition information indicates that the vehicle passes through the first type of road section again, the prompt device is controlled to prompt the user to turn on the anti-motion sickness device.

[0043] Based on the above technical solution, road condition information can store a correspondence between road section types and whether anti-motion sickness devices are enabled for that road section. For example, if a vehicle detects that a user has activated anti-motion sickness devices when passing through a road section with continuous curves, the vehicle can proactively prompt the user to activate anti-motion sickness devices before the vehicle passes through the same road section again. This storage of this correspondence eliminates the need for users to proactively activate anti-motion sickness devices, helping to avoid tedious user operations and thus improving the user's driving experience.

[0044] In some possible implementations, the road condition information may further include a correspondence between the type of road segment and the type of anti-motion sickness device activated by the user for the type of road segment.

[0045] For example, the road condition information may also include a correspondence between a road section with continuous turns and a vehicle body control device; and a correspondence between a damaged road section and a vehicle body control device and a display device.

[0046] In combination with the first aspect, in certain implementations of the first aspect, the motion information includes a first MSDV, and the anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information, and the physiological characteristic information, including: when the first MSDV is greater than or equal to a first preset threshold, controlling the prompt device to prompt the user to turn on the anti-motion sickness device; and according to the user's second input, controlling the anti-motion sickness device not to turn on and establishing an association relationship between the user and a second preset threshold, the second preset threshold being determined by the first MSDV, and the second input indicating not to turn on the anti-motion sickness device.

[0047] Based on the above technical solution, since different users have different tolerances to motion sickness, a correspondence can be established between users and preset thresholds. For example, for users with a high tolerance for motion sickness, they can be prompted when the MSDV is high; for users with a low tolerance for motion sickness, they can be prompted when the MSDV is low. This allows for precise control tailored to different users, helping to enhance the vehicle's intelligence.

[0048] In combination with the first aspect, in certain implementations of the first aspect, the method further includes: obtaining another motion information of the vehicle, the other motion information including a second MSDV of the vehicle when the user is in the vehicle; when the second MSDV is greater than or equal to the second preset threshold, controlling the prompt device to prompt the user to turn on the anti-motion sickness device.

[0049] The above-mentioned controlling the anti-motion sickness device to be turned on may be understood as controlling the anti-motion sickness device to perform the anti-motion sickness operation, and controlling the anti-motion sickness device not to be turned on includes controlling the anti-motion sickness device to maintain the current state unchanged.

[0050] In a second aspect, an anti-motion sickness device is provided, which includes: an acquisition unit for acquiring vehicle motion information, road condition information and physiological characteristic information of a user; and a control unit for controlling the anti-motion sickness device in the vehicle to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information.

[0051] In combination with the second aspect, in certain implementations of the second aspect, the anti-motion sickness device includes multiple devices, and the control unit is used to control at least some of the multiple devices to perform corresponding operations based on the situation in which preset conditions are met in the motion information, the road condition information, and the physiological characteristic information.

[0052] In combination with the second aspect, in certain implementations of the second aspect, the multiple devices include a body control device, a display device, and an occupant environment device, and the control unit is used to: when the physiological characteristic information meets the preset condition, control the body control device, the display device, and the occupant environment device to perform corresponding operations.

[0053] In combination with the second aspect, in certain implementations of the second aspect, the multiple devices include a body control device, a display device, and an occupant environment device, and the control unit is used to: when the motion information meets the preset condition and the physiological characteristic information does not meet the preset condition, control the body control device to perform corresponding operations.

[0054] In combination with the second aspect, in some implementations of the second aspect, the user is located in a first area in the vehicle, and the at least part of the device is associated with the first area.

[0055] In combination with the second aspect, in certain implementations of the second aspect, the control unit is used to: when at least part of the motion information, the road condition information, and the physiological characteristic information meets the preset condition, control the prompt device to prompt the user to turn on at least part of the device; and control the at least part of the device to turn on according to the user's first input, and the first input indicates to turn on at least part of the device.

[0056] In combination with the second aspect, in certain implementations of the second aspect, the road condition information includes location information, which indicates that the anti-motion sickness device was turned on when the vehicle previously passed through the first section. The control unit is used to: before detecting that the vehicle passes through the first section again, control the prompt device to prompt the user to turn on the anti-motion sickness device.

[0057] In combination with the second aspect, in certain implementations of the second aspect, the road condition information includes road surface information, the location information indicates that the vehicle previously turned on the anti-motion sickness device when passing through a first type of road section, and the control unit is used to: before detecting that the vehicle passes through the first type of road section again, control the prompt device to prompt the user to turn on the anti-motion sickness device.

[0078] Figure 1 is a functional block diagram of a vehicle 100 provided in an embodiment of the present application. The vehicle 100 may include a perception system 110, a computing platform 120 and a display device 130, wherein the perception system 110 may include one or more sensors for sensing information about the environment surrounding the vehicle 100. For example, the perception system 110 may include a positioning system, and the positioning system may be a global positioning system (GPS), or a BeiDou system or other positioning systems. For another example, the perception system 110 may include one or more of an inertial measurement unit (IMU), an acceleration sensor, a lidar, a millimeter-wave radar, an ultrasonic radar, and a camera device. Exemplarily, the acceleration sensor may include a sensor for detecting the acceleration signal of an air suspension system, or may also include a sensor for the acceleration signal of an ESC.

[0079] Some or all functions of the vehicle 100 may be controlled by a computing platform 120. The computing platform 120 may include one or more processors, such as processors 121 to 12n (n is a positive integer). A processor is a circuit capable of processing signals. In one implementation, the processor may be a circuit capable of reading and executing instructions, such as a central processing unit (CPU), a microprocessor, a graphics processing unit (GPU) (which can be understood as a microprocessor), or a digital signal processor (DSP). In another implementation, the processor may implement certain functions through the logical relationships of a hardware circuit. The logical relationships of the hardware circuit may be fixed or reconfigurable. For example, the processor may be a hardware circuit implemented by an application-specific integrated circuit (ASIC) or a programmable logic device (PLD), such as a field programmable gate array (FPGA). In a reconfigurable hardware circuit, the process of the processor loading a configuration file to implement the hardware circuit configuration can be understood as the process of the processor loading instructions to implement the functions of some or all of the above units. In addition, the processor may also be a hardware circuit designed for artificial intelligence, which can be understood as an ASIC, such as a neural network processing unit (NPU), a tensor processing unit (TPU), a deep learning processing unit (DPU), etc. In addition, the computing platform 120 may also include a memory for storing instructions, and some or all of the processors 121 to 12n may call the instructions in the memory to implement corresponding functions.

[0080] The display devices 130 in the cockpit are mainly divided into two categories: the first is the vehicle-mounted display screen; the second is a projection display screen, such as a head-up display (HUD). The vehicle-mounted display screen is a physical display screen and a key component of the in-vehicle infotainment system. The cockpit can be equipped with multiple displays, such as the digital instrument panel, the central control screen, the display in front of the front passenger (also known as the front passenger), the display in front of the left rear passenger, and the display in front of the right rear passenger. Even the vehicle windows can serve as display screens. A head-up display, also known as a head-up display system, is primarily used to display driving information such as speed and navigation on a display device in front of the driver (such as the windshield). This reduces the driver's gaze shift time, avoids pupil changes caused by the driver's gaze shift, and improves driving safety and comfort. HUDs include, for example, combiner-HUD (C-HUD), windshield-HUD (W-HUD), and augmented reality HUD (AR-HUD). It should be understood that other types of HUD systems may appear as technology evolves, and this application is not limited to this.

[0081] The above display device 130 is described by taking a vehicle-mounted display screen and a projection display screen as examples, and the embodiments of the present application are not limited thereto. For example, the display device 130 can also be a light display screen or a projection screen.

[0082] Figure 2 shows a schematic block diagram of a system architecture 200 provided in an embodiment of the present application. As shown in Figure 2, the system architecture 200 includes a detection module 210, a control module 220 and an execution module 230. The execution module 230 may include multiple submodules, such as a body control device, a display device and an occupant environment device. The body control device includes air springs, shock absorbers, a braking system, a power system (acceleration, energy recovery), seats, etc. By controlling one or more devices in the body control device, the vehicle's motion state can be controlled, thereby reducing motion stimulation. The display device may include a display screen, a curtain, an ambient light, etc. When the user uses the screen and the curtain, the visual conflict when the user views the screen can be alleviated by adjusting the screen angle, screen display parameters, etc. The occupant environment device may include air conditioning, fragrance, music playback equipment, and other equipment that can improve the user's riding environment factors.

[0083] Adjusting the screen angle or display parameters above can enable the user to keep their head naturally upright when viewing the screen. For example, the control module 220 can adjust the laser projection image to move upward from a lower position in the displayable area of ​​the screen, so that the user can move their head upright instead of bowing it.

[0084] The detection module 210 can be used to collect physiological characteristic information of users in the cabin, road condition information, and vehicle motion information. For example, the physiological characteristic information may include one or more of the data collected by wearable devices (such as bracelets, watches, head-mounted devices, virtual reality (VR) devices, etc.), images collected by cameras in the cabin, or voice information collected by microphones. The data collected by wearable devices may include heart rate, blood oxygen, EEG, and other information that can characterize the degree of motion sickness of the user. The images collected by the camera in the cabin may include information about the user's facial features (for example, facial features information can be used to characterize information such as yawning, nausea, vomiting, and eye movements of the user). The voice information collected by the microphone may include key phrases for motion sickness, such as key voice information such as "I feel a little dizzy, I feel more dizzy, and I feel a little nauseous."

[0085] Road condition information may include data collected by an external camera or radar, or may include one or more items of navigation information. For example, data collected by an external camera or radar, or navigation information, may determine road conditions such as mountain roads, continuous curves, and road construction.

[0086] The motion information may include one or more of the following: vehicle acceleration, seat pressure, vehicle speed sensor, pedal signal, steering wheel angle, and angular velocity. Detection module 210 may transmit the collected data to control module 220. Control module 220 may control execution module 230 to perform corresponding operations based on the data transmitted by detection module 210.

[0087] For example, when the vehicle's motion information and the user's physiological characteristic information meet the preset conditions, all devices in the execution module 230 can be controlled to perform corresponding operations. For example, when only the vehicle's motion information meets the preset conditions, the body control device in the execution module 230 can be controlled to perform corresponding operations.

[0088] Exemplarily, the preset conditions include preset conditions for physiological characteristic information, preset conditions for road condition information, and preset conditions for motion information.

[0089] For example, the preset conditions for physiological characteristic information include but are not limited to at least one of the following:

[0090] (1) The voice message sent by the user includes motion sickness keywords;

[0091] (2) The user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude; or, the user's heart rate variability time domain index decreases and the variation amplitude is greater than or equal to the first preset amplitude; or, the user's heart rate variability low-frequency component increases and the increase amplitude is greater than or equal to a third preset amplitude; or, the user's heart rate variability high-frequency component decreases and the decrease amplitude is greater than or equal to a fourth preset amplitude;

[0092] (3) The user yawns, feels nauseous, or vomits.

[0093] When the physiological characteristic information of the above user meets any one or more of the above preset conditions, the control module 220 can determine that the physiological characteristic information of the user meets its corresponding preset condition.

[0094] For another example, the preset conditions for road condition information include but are not limited to at least one of the following:

[0095] (1) The vehicle is on a continuous curve;

[0096] (2) The vehicle is on a damaged road or road under construction.

[0097] For another example, the preset conditions for motion information include but are not limited to at least one of the following:

[0098] (1) The number of times the vehicle suddenly accelerates, decelerates, or turns in a predetermined direction within a predetermined time period is greater than or equal to the predetermined number;

[0099] (2)MSDV is greater than or equal to the preset threshold.

[0100] For example, when the physiological characteristic information, road condition information, and movement information meet preset conditions, the control module can classify the user's motion sickness degree into different motion sickness degrees. For example, Table 1 shows a classification method for motion sickness degrees.

[0101] Table 1

[0102] For example, if the control module 220 determines, based on the data collected by the detection module 210, that the user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude, the vehicle is currently on a continuous curve, and the MSDV is greater than a preset threshold, then the user's motion sickness level may be determined to be high. Based on the correspondence between the motion sickness level and the execution module, the control module 220 may control the corresponding device to perform motion sickness prevention operations. For example, Table 2 shows the correspondence between motion sickness level and device.

[0103] Table 2

[0104] For example, when the control module 220 determines that the user's motion sickness level is high, it can control the vehicle body control device, display device, and passenger environment equipment. For example, the control module 220 can control the vehicle to activate comfort braking, control the vehicle body height to be lowered, control the angle of the display screen, and control the activation of fragrance.

[0105] For example, when the control module 220 determines that the user's motion sickness level is low, it can control the vehicle body control device to work. For example, the control module 220 can control the vehicle to turn on the comfort brake and control the vehicle body height to be lowered.

[0106] The above Tables 1 and 2 are merely illustrative, and the classification of motion sickness degrees in the embodiments of the present application is not limited thereto.

[0107] In the above embodiment, the degree of motion sickness is determined by physiological characteristic information, motion information, and road condition information. However, the present invention is not limited thereto. For example, the degree of motion sickness can also be determined by motion information.

[0108] For example, the motion sickness degree is divided by different MSDVs indicated by the motion information. For example, Table 3 shows a method for dividing the motion sickness degree.

[0109] Table 3

[0110] The MSDV in Table 3 above is merely illustrative and is not specifically limited in the present embodiment.

[0111] For example, when the MSDV is 3.5, the control module 220 may control the vehicle to activate comfort braking, control the vehicle body height to be lowered, control the angle of the display screen, and control the activation of fragrance.

[0112] For example, when the MSDV is 2.5, the control module 220 may control the vehicle to activate comfort braking and control the vehicle body height to be lowered.

[0113] For example, the degree of motion sickness can also be divided according to physiological characteristic information. For example, Table 4 shows a method for dividing the degree of motion sickness.

[0114] Table 4

[0115] For example, when the data collected by the camera in the cockpit determines that the user is experiencing nausea or vomiting, or when the voice information collected by the microphone recognizes the key words for motion sickness, the control module 220 can control the vehicle to activate comfort braking, control the vehicle body height to be lowered, control the angle of the display screen, and control the activation of the fragrance.

[0116] For example, when the data sent by the wearable device indicates that the user's heart rate is greater than or equal to a preset heart rate value, the control module 220 can control the vehicle to activate comfort braking and control the vehicle body height to be lowered.

[0117] In one embodiment, the control module 220 may prompt the user to turn on the motion sickness relief mode through a prompting device before controlling one or more devices to perform the anti-motion sickness operation.

[0118] Exemplarily, FIG3 shows a graphical user interface (GUI) provided in an embodiment of the present application.

[0119] As shown in Figure 3, when the vehicle detects that the user's physiological characteristics, road conditions, and vehicle movement information meet preset conditions, the vehicle can prompt the user through the speaker, "Detected that the current scene is prone to motion sickness. Do you want to enable motion sickness relief mode?" If the user issues a voice command "Enable motion sickness relief mode," the vehicle can activate comfort braking, lower the vehicle body height, adjust the display screen angle, and activate fragrance.

[0120] In one embodiment, when the vehicle is traveling through road section 1, it is detected that the user has actively activated the motion sickness relief mode, or when the user is prompted to activate the motion sickness relief mode through a prompting device and the user confirms that the motion sickness relief mode has been activated. Before the vehicle passes through road section 1 again, the prompting device may prompt the user, "The motion sickness relief mode was activated when passing road section 1 last time. Do you want to activate the motion sickness relief mode in advance?" When the user's voice command "activate motion sickness relief mode" is detected, the vehicle may activate comfort braking, control the vehicle body height to be lowered, control the angle of the display screen, and control the activation of fragrance in advance before passing road section 1.

[0121] In one embodiment, the control module 220 can also correct the degree of motion sickness of the user. Take the degree of motion sickness and MSDV shown in Table 3 as an example. When the MSDV (for example, 3.4) is greater than the first preset threshold (for example, 3.3), the control module 220 can control the speaker to emit a prompt sound "It is detected that motion sickness is prone to occur in the current environment, whether to turn on the motion sickness relief mode". When the voice command "Do not turn on the motion sickness relief mode" issued by user A is detected, the vehicle can control the status of each anti-motion sickness device to remain unchanged. At the same time, the vehicle can establish an association relationship between the identification information of user A and a second preset threshold, and the second preset threshold is greater than the first preset threshold, such as the second preset threshold can be 3.4.

[0122] When user A drives the vehicle through another road section, if it is detected that the MSDV is less than the second preset threshold, the vehicle may not perform anti-motion sickness operation; or, if it is detected that the MSDV (for example, 3.5) is greater than the second preset threshold, the vehicle can control the speaker to emit a prompt sound "It is detected that motion sickness is prone to occur in the current environment, do you want to turn on the motion sickness relief mode?"

[0123] The above describes the process by which a vehicle proactively performs anti-motion sickness operations or controls a prompt device to prompt a user to activate motion sickness relief mode when determining that at least part of the physiological characteristic information, road condition information, and motion information meets preset conditions. The following describes the process by which a user activates motion sickness relief mode through operation.

[0124] Exemplarily, FIG4 shows a set of GUIs provided in an embodiment of the present application.

[0125] The display interface of the driving tab shown in (a) of FIG4 includes a motion sickness relief mode control 401. When detecting that the user has turned on the motion sickness relief mode, the vehicle can control various devices to perform corresponding motion sickness prevention operations.

[0126] In one embodiment, the user can also set the devices that need to be turned on.

[0127] As shown in FIG. 4( a ), when it is detected that the user clicks on the device selection control 402 , a GUI as shown in FIG. 4( b ) may be displayed on the display screen.

[0128] As shown in (b) of Figure 4, the vehicle can display a motion sickness relief mode setting interface, which includes three controls, corresponding to turning on or off the body control motion sickness relief, turning on or off the optical display motion sickness relief, and turning on or off the passenger environment motion sickness relief. For example, the user can turn on these three controls and return to the previous page. When the vehicle detects that the user has turned on the motion sickness relief mode on the interface shown in (a) of Figure 4, it can control the body control device, display device, and passenger environment equipment to perform anti-motion sickness operations.

[0129] For another example, if a user turns on both body control and optical display motion sickness relief, and turns off passenger environment motion sickness relief, the vehicle can control the body control device and display device to perform motion sickness prevention operations when detecting that the user has turned on motion sickness relief mode on the interface shown in FIG4(a).

[0130] In one embodiment, if the vehicle detects that a user in the passenger seat has activated motion sickness relief mode, the vehicle can control the anti-motion sickness device in the passenger seat to perform a corresponding operation. For example, the vehicle can control at least one of the following: opening the passenger seat window to 90%, dimming the passenger seat display screen, adjusting the air conditioning mode in the passenger seat to face-blowing mode, or adjusting the seat angle in the passenger seat.

[0131] Figure 5 shows another schematic block diagram of the system architecture provided by an embodiment of the present application. Among them, the detection module 210 may include a driver monitoring system (DMS) 211, a cabin monitoring system (CMS) 212, a microphone 213, a millimeter wave radar 214, a lidar 215 and an inertial measurement unit (IMU) 216. The control module 220 may include an intelligent cockpit domain controller (CDC) 221, an intelligent driving computing platform / mobile data center (MDC) 222, a vehicle domain controller (VDC) 223 and a vehicle integration unit (VIU) 224, etc. Among them, CDC221 can be used to implement cockpit control, MDC220 can be used to implement the vehicle's automatic driving or assisted driving functions, and VDC223 can be used to implement vehicle function control (for example, steering or braking, etc.). The execution module 230 may include a display screen 231, an electrical brake system (EBS) 232, an electronic controlled air suspension system (ECAS) 233, an electronic damping control system (EDC) 234, an air conditioner 235, a fragrance 236, and a seat 237, etc.

[0132] Sensors and actuators (e.g., ECAS, EDC, etc.) can be connected to the VIU nearby. The VIU, as a communication interface unit, can be deployed in densely populated areas of the vehicle's sensors and actuators, allowing for close access. The VIU can also possess certain computing and actuation capabilities (e.g., it can absorb the actuation computing functions of some actuators).

[0133] For example, the data collected by the camera in DMS211 can be sent to CDC221, and CDC221 can send the data collected by the camera to VDC223. VDC223 can determine the user's facial features (for example, whether the user is experiencing nausea, vomiting, etc.) based on the data collected by the camera. When VDC223 determines that the user is vomiting, it can send instruction 1 to CDC221. Instruction 1 is used to instruct the angle of the display screen to be adjusted to an angle at which the user can view the display screen when the user's head is naturally upright. When CDC221 receives instruction 1, it can control the angle of the display screen to be adjusted to the target angle. VDC223 can also control the acceleration mode of the vehicle to be adjusted to the economy mode and control the energy recovery intensity to be reduced. VDC223 can also send instruction 2 to VIU224. Instruction 2 is used to instruct the fragrance 236 to be turned on. After receiving instruction 2, VIU224 can control the fragrance 236 to be turned on.

[0134] The above description is based on a ring network communication architecture as an example, and the present invention is not limited thereto. The functions implemented by the control module 220 can also be implemented by a controller or a processor, and the present invention is not limited thereto.

[0135] The mobile data center, cockpit domain controller, vehicle domain controller, zone controller, vehicle integrated unit, etc. described in the embodiments of this application may also have other names. This application only uses MDC, CDC, VDC, VIU, etc. as examples, and is not a limitation to the specific implementation methods.

[0136] FIG6 shows a schematic flow chart of a motion sickness prevention method 600 provided in an embodiment of the present application. The method 600 can be executed by the vehicle 100, or by the computing platform 120, or by a system consisting of the computing platform 120 and a prompt device (e.g., the display device 130), or by a system-on-a-chip (SoC) in the computing platform 120, or by a processor, chip, or circuit in the computing platform 120, or by the control module 220. The method 600 includes:

[0137] S610: Acquire vehicle motion information and user physiological characteristic information.

[0138] Optionally, the motion information includes one or more of data collected by the vehicle's acceleration sensor, seat pressure, data collected by a speed sensor, a pedal signal, a steering wheel angle, and an angular velocity.

[0139] Exemplarily, the data collected by the acceleration sensor may include an acceleration signal of an air suspension system, or an acceleration signal of an ESC.

[0140] Optionally, the motion information includes MSDV.

[0141] Optionally, the physiological characteristic information includes: information such as the user's heart rate, blood oxygen level, and electroencephalogram (EEG) that can be used to indicate the degree of motion sickness; and / or information about the user's facial features or voice. For example, the facial features information may include yawning, nausea, vomiting, eye movements, and other sensory information. Another example is that the voice information may include motion sickness keywords, such as "I feel a little dizzy."

[0142] Optionally, obtaining physiological characteristic information includes: obtaining physiological characteristic information sent by a wearable device.

[0143] For example, user A is located in the second row, left side area of ​​the vehicle, and user A's smartwatch establishes a short-range communication connection with the vehicle (e.g., Bluetooth connection or StarFlash connection). User A's smartwatch can send user A's heart rate information to the vehicle. When the vehicle determines that the amplitude of user A's heart rate fluctuation is greater than or equal to a first preset amplitude, it can determine the orientation of the smartwatch using angle of arrival (AOA) technology. When it is determined that the smartwatch is located in the second row, left side area of ​​the vehicle, the windows in the second row, fragrance in the second row, and the air conditioning mode in the second row can be adjusted to face-blowing mode.

[0144] Optionally, obtaining the physiological characteristic information includes: determining the physiological characteristic information based on data collected by an in-cabin sensor, where the in-cabin sensor includes one or more of an in-cabin camera, a radar, and a microphone.

[0145] For example, multiple microphones in the cabin can collect user voice information. For example, if user B says, "I feel a little dizzy," the vehicle can use the voice information collected by multiple microphones to determine user B's location. For example, if it is determined that user B is in the right side of the second row, the vehicle can control the windows in the right side of the second row to open, the fragrance in the right side of the second row to be turned on, and the air conditioning mode in the right side of the second row to be adjusted to face-blowing mode.

[0146] S620: Control the anti-motion sickness device in the vehicle to perform corresponding operations according to the motion information and the physiological characteristic information.

[0147] Optionally, the anti-motion sickness device includes multiple devices, which controls the anti-motion sickness devices in the vehicle to perform corresponding operations based on the motion information and the physiological characteristic information, including: controlling at least some of the multiple devices to perform corresponding operations based on the situation that preset conditions are met in the motion information and the physiological characteristic information.

[0148] Optionally, the preset conditions include preset conditions for operation information and preset conditions for physiological characteristic information.

[0149] For example, the preset conditions for running information include but are not limited to at least one of the following: the voice information sent by the user includes motion sickness keywords; or, the user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude; or, the user's heart rate variability time domain index becomes smaller and the variation amplitude is greater than or equal to the first preset amplitude; or, the user's heart rate variability low-frequency component increases, and the increase amplitude is greater than or equal to a third preset amplitude; or, the user's heart rate variability high-frequency component decreases, and the decrease amplitude is greater than or equal to a fourth preset amplitude; or, the user yawns, feels nauseous, or vomits.

[0150] For another example, the preset conditions for physiological characteristic information include but are not limited to at least one of the following: the number of times the vehicle experiences sudden acceleration, sudden deceleration, or sudden turn within a preset time period is greater than or equal to a preset number; the MSDV is greater than or equal to a preset threshold.

[0151] Optionally, the multiple devices include a body control device, a display device and an occupant environment device, and based on the situation that the motion information and the physiological characteristic information meet the preset conditions, at least some of the multiple devices are controlled to perform corresponding operations, including: when the physiological characteristic information meets the preset conditions, controlling the body control device, the display device and the occupant environment device to perform corresponding operations.

[0152] Optionally, the preset conditions for different physiological characteristic information may have different priorities. For example, the priority of the preset condition that the user's voice message includes a key word for motion sickness is high. For another example, the priority of the preset condition that the user yawns, feels nauseous, or vomits is medium. For another example, the priority of the preset condition that the user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude is low.

[0153] When physiological characteristic information meets preset conditions of different priorities, different devices can be controlled to perform corresponding anti-motion sickness operations. For example, when the user's voice information contains motion sickness keywords, the body control device, the display device, and the passenger environment device can be controlled to perform corresponding operations. For another example, when the user is detected to be yawning, nausea, vomiting, etc., the body control device and the passenger environment device can be controlled to perform corresponding operations. For another example, when the user's heart rate fluctuation amplitude is detected to be greater than or equal to a first preset amplitude, the passenger environment device can be controlled to perform corresponding operations.

[0154] For example, Table 5 shows the corresponding recommended modes of various devices in the motion sickness relief mode.

[0155] Table 5

[0156] The above Table 5 is merely illustrative, and the embodiments of the present application do not specifically limit the types and recommended modes of anti-motion sickness devices.

[0157] Optionally, the multiple devices include a body control device, a display device and an occupant environment device, which controls at least some of the multiple devices to perform corresponding operations based on the motion information and the physiological characteristic information satisfying preset conditions, including: when the motion information satisfies the preset conditions and the physiological characteristic information does not satisfy the preset conditions, controlling the body control device to perform corresponding operations.

[0158] Exemplarily, controlling the vehicle body control device to perform corresponding operations includes at least one of the following: controlling the vehicle's acceleration mode to be an economic mode, controlling the energy recovery intensity to be reduced, controlling the vehicle body height to be reduced, or controlling the comfort braking mode to be turned on.

[0159] Optionally, based on the situation that the motion information and the physiological characteristic information meet the preset conditions, at least some of the multiple devices are controlled to perform corresponding operations, including: when the motion information and at least some of the physiological characteristic information meet the preset conditions, controlling the prompt device to prompt the user to turn on at least some of the devices; based on the user's first input, controlling at least some of the devices to turn on, the first input indicating to turn on at least some of the devices.

[0160] For example, as shown in FIG3 , upon determining that at least part of the motion information and the physiological characteristic information meets the preset condition, the vehicle may issue a voice prompt stating, "Detected that motion sickness is likely to occur in the current scenario. Do you want to enable motion sickness relief mode?" Upon detecting the user's voice command "Enable motion sickness relief mode," the vehicle may control the body control device, the display device, and the passenger environment device to perform corresponding operations.

[0161] The above prompting the user to activate the motion sickness relief mode can be understood as prompting the user to activate the anti-motion sickness device. For the selection of the anti-motion sickness device, reference can be made to the GUI shown in FIG4(b). Alternatively, the anti-motion sickness device can be the vehicle's default device, such as the vehicle body control device, the display device, and the passenger environment device.

[0162] Optionally, the method 600 further includes: obtaining road condition information; and controlling the anti-motion sickness device in the vehicle to perform corresponding operations based on the motion information and the physiological characteristic information, including: controlling the anti-motion sickness device in the vehicle to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information.

[0163] For example, the road condition information may include information about the road section the vehicle is currently on, such as the location and type of the road section the vehicle is currently on.

[0164] Exemplarily, obtaining road condition information includes determining the road condition information based on data collected by sensors outside the cabin, or determining the road condition information based on navigation information. For example, the sensors outside the cabin include cameras, radars, and the like.

[0165] Exemplarily, obtaining road condition information includes: determining the road condition information according to navigation information.

[0166] Optionally, based on the motion information, the road condition information and the physiological characteristic information, the anti-motion sickness device in the vehicle is controlled to perform corresponding operations, including: when at least part of the motion information, the road condition information and the physiological characteristic information meets the preset conditions, the control prompt device prompts the user to turn on at least part of the device; based on the user's first input, the at least part of the device is controlled to turn on, and the first input indicates to turn on at least part of the device.

[0167] For example, the preset conditions may include preset conditions for road condition information, including but not limited to at least one of the following: the vehicle is on a continuous bend; the vehicle is on a damaged road or a road under construction.

[0168] For example, when it is detected that the vehicle is on a continuous curve, the MSDV value is greater than or equal to a preset threshold, and the user's heart rate fluctuation amplitude is greater than or equal to a first preset amplitude, the vehicle can control the body control device, the display device, and the occupant environment equipment to perform corresponding operations.

[0169] Optionally, the user is located in a first area in the vehicle, and the at least part of the device is associated with the first area.

[0170] Optionally, the user is located in the first area of ​​the vehicle, and the anti-motion sickness equipment in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information, including: when the user's physiological characteristic information meets preset conditions, controlling the body control device to perform anti-motion sickness operations, and controlling the display device and occupant environment equipment in the first area to perform corresponding anti-motion sickness operations.

[0171] Optionally, the display device and the passenger environment equipment in the first area are controlled to perform corresponding anti-motion sickness operations, including: controlling the windows in the first area to open, controlling the operating mode of the air conditioner in the first area to adjust to the face-blowing mode, controlling the fragrance in the first area to turn on, controlling the display parameters of the display device in the first area, or controlling at least one of the air purification device in the first area to turn on.

[0172] Optionally, the vehicle cabin includes multiple users, the multiple users including a first user and a second user, the first user is located in a first area, and the second user is located in a second area, and according to the motion information, the road condition information and the physiological characteristic information, the anti-motion sickness device in the vehicle is controlled to perform corresponding operations, including: when the physiological characteristic information of the first user meets a preset condition and the physiological characteristic information of the second user does not meet the preset condition, the anti-motion sickness device in the first area is controlled to perform an aggressive anti-motion sickness operation and the anti-motion sickness device in the second area is controlled to perform a soothing anti-motion sickness operation.

[0173] Exemplarily, the first user is located in the left area of ​​the second row and the second user is located in the right area of ​​the second row. Before the anti-motion sickness operation is performed, the windows of the left area of ​​the second row and the right area of ​​the second row are closed and the brightness of their display screens is 100%. The anti-motion sickness device in the first area is controlled to perform an aggressive anti-motion sickness operation, including: opening the windows of the left area of ​​the second row to 50% and controlling the brightness of the display screens of the left area of ​​the second row to be lowered to 50%; and the anti-motion sickness device in the second area is controlled to perform a soothing anti-motion sickness operation, including: opening the windows of the right area of ​​the second row to 90% and controlling the brightness of the display screens of the right area of ​​the second row to be lowered to 70%.

[0174] Optionally, the road condition information includes location information, which indicates that the anti-motion sickness device was turned on when the vehicle passed the first road section before. The anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information, including: before the road condition information indicates that the vehicle passes the first road section again, the prompt device is controlled to prompt the user to turn on the anti-motion sickness device.

[0175] For example, Table 6 shows the correspondence between road sections and whether the anti-motion sickness device is turned on.

[0176] Table 6

[0177] For example, Road Section 1 is a section from home to Scenic Spot A. If the vehicle detects that the user has activated motion sickness prevention equipment or motion sickness relief mode while traveling along Road Section 1, this information can be recorded. The next time the vehicle passes through Road Section 1, a voice prompt can be issued through the speaker, asking, "The last time I passed Road Section 1, motion sickness relief mode was activated. Do you want to activate it this time?" Upon detecting the user's voice command "Enable motion sickness relief mode," the mode can be activated.

[0178] Optionally, the road condition information includes road surface information, which indicates that the vehicle had previously turned on the anti-motion sickness device when passing through a first type of road section. The anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information, including: before the road condition information indicates that the vehicle passes through the first type of road section again, the prompt device is controlled to prompt the user to turn on the anti-motion sickness device.

[0179] For example, Table 7 shows the correspondence between the type of road section and whether to turn on the anti-motion sickness device.

[0180] Table 7

[0181] For example, section 2 is a section from home to scenic spot B, and section 2 is a section with continuous turns. When the vehicle detects that the user has turned on the anti-motion sickness device or the motion sickness relief mode while driving on section 2, the information can be recorded. The next time the vehicle passes section 3 (for example, section 3 is also a section with continuous turns), a voice prompt can be issued through the speaker, "The motion sickness relief mode was turned on when passing the section with continuous turns last time. Do you want to turn it on this time?" When the user issues a voice command "Turn on motion sickness relief mode", the motion sickness relief mode can be controlled to be turned on.

[0182] Optionally, the motion information includes a first motion sickness dose value MSDV, and the anti-motion sickness device in the vehicle is controlled to perform corresponding operations based on the motion information, the road condition information and the physiological characteristic information, including: when the first MSDV is greater than or equal to a first preset threshold, controlling the prompt device to prompt the user to turn on the anti-motion sickness device; according to the user's second input, controlling the anti-motion sickness device not to turn on and establishing an association relationship between the user and a second preset threshold, the second preset threshold being determined by the first MSDV, and the second input instructing not to turn on the anti-motion sickness device.

[0183] Alternatively, the vehicle may determine the MSDV based on data collected by an acceleration sensor.

[0184] Optionally, the first preset threshold can be obtained from a cloud server.

[0185] Optionally, the first preset threshold may be different for different users. For example, for a male user, the first preset threshold may be 3. For a female user, the first preset threshold may be 2.8.

[0186] For example, user B is in the driver's seat. While user B is driving, if the vehicle detects that the MSDV (e.g., 3.1) is greater than or equal to a first preset threshold (e.g., 3), the vehicle may prompt user B to enable motion sickness relief mode. Upon detecting that user B issues a voice command "disable motion sickness relief mode," the vehicle may record the correspondence between user B's identification information and a second preset threshold. For example, the vehicle may record the correspondence between user B's facial information 1 and the second preset threshold.

[0187] Exemplarily, the second preset threshold may be determined by the MSDV. For example, the second preset threshold may be equal to the MSDV.

[0188] Exemplarily, Table 8 shows the correspondence between users and preset thresholds.

[0189] Table 8

[0190] Because different users have varying tolerances to motion sickness, a mapping can be established between user identification information and preset thresholds. For example, for users with a high tolerance for motion sickness, a prompt can be issued when the MSDV is high; for users with a low tolerance for motion sickness, a prompt can be issued when the MSDV is low. This allows for precise control tailored to each user, helping to enhance the vehicle's intelligence.

[0191] Optionally, the method 600 further includes: obtaining another motion information of the vehicle, the other motion information including a second MSDV of the vehicle when the user is in the vehicle; when the second MSDV is greater than or equal to the second preset threshold, controlling the prompt device to prompt the user to turn on the anti-motion sickness device.

[0192] For example, user B is in the driver's seat. While user B is driving the vehicle, if the vehicle detects that the MSDV (e.g., 3.3) is greater than or equal to a second preset threshold (e.g., 3.1), the vehicle may prompt user B to enable motion sickness relief mode. Upon detecting user B's voice command "Enable motion sickness relief mode," the vehicle may control the body control device, the display device, and the passenger environment device to perform corresponding operations.

[0193] Alternatively, when the vehicle detects user B issuing a voice command "Disable motion sickness relief mode," it can record the correspondence between user B's identification information and a third preset threshold (e.g., 3.3).

[0196] Optionally, the multiple devices include a body control device, a display device and an occupant environment device, and the control unit 720 is used to: when the physiological characteristic information meets the preset condition, control the body control device, the display device and the occupant environment device to perform corresponding operations.

[0197] Optionally, the multiple devices include a body control device, a display device and an occupant environment device, and the control unit 720 is used to: control the body control device to perform corresponding operations when the motion information meets the preset conditions and the physiological characteristic information does not meet the preset conditions.

[0198] Optionally, the user is located in a first area in the vehicle, and the at least part of the device is associated with the first area.

[0199] Optionally, the control unit 720 is used to: when at least part of the motion information, the road condition information and the physiological characteristic information meets the preset condition, control the prompt device to prompt the user to turn on at least part of the device; and control the at least part of the device to turn on according to the user's first input, and the first input indicates to turn on at least part of the device.

The control unit 720 is used to: before the road condition information indicates that the vehicle passes the first section again, control the prompt device to prompt the user to turn on the anti-motion sickness device.

[0201] Optionally, the road condition information includes road surface information, which indicates that the anti-motion sickness device was turned on when the vehicle passed through a first type of road section before.
