Description

Display method, electronic device, and vehicle

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 29, 2024, with application number 202410387072.X and application name “Display Method, Electronic Device and Vehicle”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electronic equipment, and in particular to a display method, electronic equipment, and a vehicle. Background Art

[0003] When a vehicle is in motion, some passengers may experience motion sickness due to different states of motion determined by their different senses. For example, while the vehicle is in motion, the passenger's vestibule can sense changes in the vehicle's motion state (such as acceleration, etc.) and thus determine that the passenger is in a corresponding state of motion. During this period, if a passenger looks at an object that is stationary relative to the vehicle (or has a small movement relative to the vehicle) (such as an object inside the vehicle, an electronic device carried by the passenger, etc.), the passenger's vision will determine that he or she is in a stationary state, which is different from the state of motion sensed by the passenger's vestibule, causing the passenger to experience motion sickness. This will affect the passenger's riding experience. Summary of the Invention

[0004] The present application provides a display method, an electronic device, and a vehicle.

[0005] In a first aspect, a display method is provided, the method comprising: in response to an anti-motion sickness triggering operation, determining to activate an anti-motion sickness function corresponding to at least one target passenger; obtaining motion information of a vehicle, wherein the motion information comprises one or more of the following motion information: acceleration change rate, angular velocity of steering, angular acceleration of steering, acceleration in a first direction, angular velocity in a second direction, and angular acceleration corresponding to the angular velocity in the second direction, wherein the first direction is a height direction of the vehicle and the second direction is a width direction of the vehicle; and displaying at least one display content corresponding to the motion information on at least one display device in the vehicle, wherein at least a portion of a display area of ​​the display device is within a display range corresponding to the at least one target passenger.

[0006] Based on this method, content indicating vehicle motion information (such as the visual motion sickness prevention content described below) can be displayed within the display range corresponding to a target passenger in the vehicle. This content can stimulate the passenger's self-motion illusion, allowing the passenger's vision to perceive motion information consistent with vestibular perception based on this content, thus helping to alleviate motion sickness. Furthermore, because this content is displayed within the display range corresponding to the target passenger, rather than across the entire vehicle display range, it can prevent the display from affecting passengers and drivers who do not require motion sickness prevention.

[0007] In some implementations, the anti-motion sickness triggering operation can be an operation by the passenger based on the equipment in the vehicle (such as the vehicle computer, the vehicle-mounted tablet computer, etc.) or the interaction between the passenger's electronic device and the vehicle to turn on the anti-motion sickness function of the passenger's seat or the seats where other passengers are located. It can also be an operation by the passenger on the buttons, switches, etc. in the vehicle used to turn on the anti-motion sickness function.

[0008] In a possible implementation of the first aspect, the motion information further includes at least one of the following motion information: acceleration in a third direction, speed in the third direction, and acceleration in the second direction, wherein the third direction is the length direction of the vehicle.

[0009] In a possible implementation of the first aspect above, the at least one display device includes a first display device extending along a first direction, and / or a second display device extending along a second direction, and / or a third display device extending along a third direction; and at least one display device in the vehicle displays at least one display content corresponding to motion information, including: displaying the following display content corresponding to the motion information based on at least a partial display area corresponding to the first display device: acceleration in the first direction, the rate of change of acceleration in the first direction, the angular velocity in the second direction, and the angular acceleration corresponding to the angular velocity in the second direction; or, displaying the following display content corresponding to the motion information based on at least a partial display area corresponding to the second display device: angular velocity of steering, angular acceleration of steering, acceleration in the second direction, and the rate of change of acceleration in the second direction; or, displaying the following display content corresponding to the motion information based on at least a partial display area corresponding to the third display device: acceleration in the third direction, the rate of change of acceleration in the third direction, and the speed in the third direction.

[0010] In this implementation, a display device extending in one direction may be used to display content corresponding to motion information in that direction (eg, visual anti-sickness content described below).

[0011] In some examples, considering the actual structure of the vehicle, a display device or lamp extending in a certain direction may not extend strictly in that direction. For example, a strip of ambient light extending along the length of the vehicle may have different ends at different heights, but may have a certain degree of inclination. Alternatively, the strip of ambient light may have some protrusions or depressions in the middle of the height direction, giving the strip a wavy or jagged shape. It should be understood that the ambient light in the above examples is also understood to be an ambient light extending along the length of the vehicle.

[0012] In a possible implementation of the first aspect above, the display range corresponding to the at least one target passenger is determined based on at least one of the target passenger's field of view, the target passenger's position, the seat corresponding to the target passenger, the distribution of display devices in the vehicle, and the distribution of objects in the vehicle.

[0013] In this implementation, the display range corresponding to the target passenger can be determined based on the target passenger's field of view, the target passenger's location, the target passenger's corresponding seat, the distribution of display devices in the vehicle, and the distribution of objects in the vehicle. This makes it easier for the target passenger to see the displayed content. Display devices obscured by objects in the vehicle can be disabled, reducing energy consumption.

[0014] In a possible implementation of the first aspect above, there is at least one non-target passenger in the vehicle; and the display range corresponding to the at least one target passenger includes at least part of the field of view of the at least one target passenger and does not include at least part of the field of view of the at least one non-target passenger.

[0015] In this implementation, the display content is displayed within the display range corresponding to the target passenger. For non-target passengers within the partial field of view, even if a display device is present within the target passenger's field of view, the visual anti-sickness content is not displayed on that portion of the display device. This prevents the display content from affecting passengers and drivers who do not require anti-sickness functionality. Alternatively, the aforementioned display content (visual anti-sickness content) can be displayed on a display device (or a portion of a display device) that is within the target passenger's field of view (or the field of view that the target passenger can see when moving) and not within the field of view of non-target passengers (or within the field of view of non-target passengers but not likely to cause non-target passengers to be affected).

[0016] In a possible implementation of the first aspect above, at least one display device in a vehicle displays at least one display content corresponding to the motion information, including: determining at least one motion information in the motion information that satisfies a first condition; displaying at least one display content corresponding to the at least one motion information that satisfies the first condition on the at least one display device; wherein the first condition includes at least one of the following conditions: the acceleration in the first direction, or the acceleration in the second direction, or the acceleration in the third direction is greater than the acceleration threshold, the acceleration change rate is greater than the acceleration change rate threshold, the angular velocity of the steering is greater than the first angular velocity threshold, the angular acceleration of the steering is greater than the first angular acceleration threshold, the angular velocity in the second direction is greater than the second angular velocity, and the angular acceleration corresponding to the angular velocity in the second direction is greater than the second angular acceleration threshold.

[0017] In this implementation, if one or more motion information does not meet the first condition (such as the anti-motion sickness condition below), it means that the one or more motion information has not reached the threshold value of causing motion sickness in passengers, and there is no need to display the display content indicating the one or more motion information, which is conducive to reducing energy consumption.

[0018] Optionally, the first angular velocity threshold and the second angular velocity threshold may be the same or different; the first angular acceleration threshold and the second angular acceleration threshold may be the same or different.

[0019] Optionally, the acceleration thresholds corresponding to accelerations in different directions may be the same or different.

[0020] Optionally, the acceleration change rate thresholds corresponding to the acceleration change rates in different directions may be the same or different.

[0021] In a possible implementation of the first aspect above, a change in content characteristics of the above-mentioned display content indicates a change in motion information, wherein the content characteristics include at least one of the following characteristics: change speed, spatial frequency, size, color, contrast, brightness, sparseness or density.

[0022] In this implementation, a content feature of content displayed on a display device can be used to indicate motion information.

[0023] In a possible implementation of the first aspect, the variation range of the content feature is determined based on lighting information in the vehicle, where the lighting information includes at least one of the following information: light brightness, light color, and color temperature.

[0024] In this implementation, the range of content features of the displayed content can be configured according to the lighting information in the vehicle, which can avoid the target passengers being unable to accurately perceive the displayed content due to the content features of the displayed content being similar or confused with the lighting information in the vehicle, thereby improving the accuracy of alleviating passengers' motion sickness.

[0025] In a possible implementation of the first aspect above, the method further includes: playing audio corresponding to the motion information, wherein a change in the audio features of the audio indicates a change in the motion information, and the audio features include at least one of the following features: frequency, loudness, timbre, sound and image movement speed, rhythm, and tempo.

[0026] In this implementation, in addition to displaying the motion-indicating content, audio indicating the motion information can be further played. This allows the passenger's visual, auditory, and vestibular perceptions of the motion information to be consistent, further alleviating the passenger's motion sickness.

[0027] In a possible implementation of the first aspect, the range of the audio feature of the audio is determined based on the audio feature of the ambient sound in the vehicle.

[0028] In this implementation, the range of the audio features of the audio can be configured according to the audio features of the ambient sounds in the vehicle, which can avoid the target passenger being unable to accurately hear the audio indicating motion information due to the audio features of the audio being similar to or confused with the ambient sounds in the vehicle, thereby improving the accuracy of alleviating passengers' motion sickness.

[0029] In a possible implementation of the first aspect, the display device includes at least one of the following devices: a display screen, a projector, and a lamp.

[0030] In this implementation, the lamps may include, but are not limited to, ambient lights, light bars, light strips, luminous interiors, decorative lights at the borders of the screen, etc. in the vehicle.

[0031] In a possible implementation of the first aspect, the obtaining of the vehicle's motion information includes: predicting the vehicle's motion information based on historical motion information of the vehicle.

[0032] In this implementation, the vehicle's motion information is predicted based on the vehicle's historical motion information. In this way, the display content indicating the motion information can be displayed before the movement corresponding to the vehicle's motion information occurs, so that passengers can feel the upcoming movement in advance, which is conducive to further alleviating the accuracy of passengers' motion sickness.

[0033] In a second aspect, a display method is provided, which includes: in response to an anti-motion sickness trigger operation, determining to turn on an anti-motion sickness function corresponding to at least one target passenger; obtaining motion information of the vehicle, wherein the motion information includes one or more of the following motion information: acceleration change rate, angular velocity of steering, angular acceleration of steering, acceleration in a first direction, angular velocity in a second direction, and angular acceleration corresponding to the angular velocity in the second direction, wherein the first direction is a height direction of the vehicle and the second direction is a width direction of the vehicle; displaying at least one display content corresponding to the motion information on at least one lamp in the vehicle, wherein at least part of the light-emitting unit of the lamp is within a display range corresponding to at least one target passenger, and the at least one lamp includes a first lamp extending along the first direction, and / or a second lamp extending along the second direction, and / or a third lamp extending along a third direction, and the third direction is a length direction of the vehicle.

[0034] In a possible implementation of the second aspect, the motion information further includes at least one of the following motion information: acceleration in the third direction, speed in the third direction, and acceleration in the second direction.

[0035] In a possible implementation of the second aspect above, the above-mentioned display content is a flowing light, and the change of the content characteristics of the flowing light indicates the change of motion information, wherein the content characteristics include at least one of the following characteristics of the flowing light: flow speed, spatial frequency, color, contrast, brightness, density or sparseness, and flow direction.

[0036] In a possible implementation of the second aspect, the variation range of the content feature is determined based on lighting information in the vehicle, where the lighting information includes at least one of the following information: light brightness, light color, and color temperature.

[0037] In a possible implementation of the second aspect, the at least one lamp in the vehicle displays at least one display content corresponding to the motion information, including: a flowing light based on the first lamp displaying a flow direction opposite to the speed in the first direction, or opposite to the acceleration in the first direction, and the content characteristics of the flowing light displayed by the first lamp are used to indicate at least one of the following motion information: acceleration in the first direction, rate of change of acceleration in the first direction, angular velocity in the second direction, angular acceleration corresponding to the angular velocity in the second direction; or, a flowing direction based on the second lamp displaying a flow direction opposite to the direction of the turn, or Or, a flowing light based on a third light fixture that displays a flow direction opposite to the direction of the speed in the third direction or opposite to the direction of the acceleration in the third direction, and the content characteristics of the flowing light displayed by the third light fixture are used to indicate at least one of the following motion information: the angular velocity of the turn, the angular acceleration of the turn, the acceleration in the second direction, and the rate of change of acceleration in the second direction.

[0066] The technical solution in this application will be described below with reference to the accompanying drawings.

[0067] To facilitate understanding, the technical terms that may be involved in this application are first introduced.

[0068] motion sickness

[0069] Motion sickness is a type of motion sickness, a syndrome caused by physical and / or visual motion.

[0070] Motion sickness (for example, motion sickness) is a condition that passengers often experience when riding in a vehicle, and visual-vestibular conflict is the main cause of motion sickness caused by passengers watching screens in the vehicle. Specifically, the vestibular system can be used to obtain the acceleration changes on the front, back, left, right, and up and down axes generated when the vehicle accelerates, decelerates, turns, and bumps, and may perceive that the passenger is currently in motion. Passengers may perceive that they are in a relatively static state by visually observing objects that are stationary relative to the vehicle or have a small range of motion relative to the vehicle (such as electronic devices and objects in the vehicle). Since the vestibular system perceives that the current passenger is in motion, while the visual system perceives that the current passenger is in a relatively static state, the different results obtained by the two perception methods conflict, causing the passenger to experience motion sickness.

[0071] Self-motion illusion

[0072] The self-motion illusion, also known as the relative motion illusion (vection, or self-motion illusion), usually refers to the illusion that the human body feels that its body is moving induced by non-physical motion stimuli (such as visual stimulation, auditory stimulation, etc.).

[0073] In order to alleviate passengers' motion sickness, the vehicle's moving images can be synchronously displayed on the vehicle's screen to stimulate the passengers' self-motion illusion, thereby alleviating motion sickness. When the vehicle is moving at a constant speed but there is a bump in the direction perpendicular to the horizontal plane, and the passenger is looking at objects inside the vehicle, the direction of motion perceived by the vestibular system is consistent with the direction of the vehicle's bump, while the visual perception is that the passenger is stationary. Therefore, the two perceptions are conflicting. When the vehicle is moving at a constant speed on a road with a changing slope, and the passenger is looking at objects inside the vehicle, the vehicle has a pitch around the left and right directions of the vehicle (for example, there is an angular velocity around the left and right directions of the vehicle). The direction of motion perceived by the vestibular system corresponds to the pitch of the vehicle, while the visual perception is that the passenger is stationary. Therefore, the two perceptions are also conflicting.

[0074] The technical solution of this application is introduced below with reference to the accompanying drawings.

[0075] For ease of description, referring to Figure 1, the left-right direction (or width direction) of the vehicle is referred to as the X direction, where the left direction of the vehicle is the X- direction and the right direction of the vehicle is the X+ direction; the front-back direction (or length direction) of the vehicle is referred to as the Y direction, where the forward direction of the vehicle is the Y+ direction and the backward direction of the vehicle is the Y- direction; the up-down direction (or height) of the vehicle is referred to as the Z direction, where the upward direction of the vehicle is the Z+ direction and the downward direction of the vehicle is the Z- direction; the rotation of the vehicle around the X direction is referred to as pitch.

[0076] In some embodiments, to alleviate motion sickness in passengers, electronic devices in the vehicle (e.g., a controller, a vehicle computer, etc.; the vehicle computer is used as an example below) can obtain the vehicle's acceleration in the Y direction and display information corresponding to the vehicle's acceleration through lighting fixtures in the vehicle (e.g., ambient lighting, etc.) (e.g., a flowing light with a flow direction opposite to the vehicle's direction of travel and a flow speed corresponding to the vehicle's acceleration). In this way, the passenger's vision can perceive the vehicle's acceleration in the Y direction based on the information corresponding to the vehicle's acceleration in the Y direction, alleviating motion sickness symptoms caused by the difference between visually perceived acceleration in the Y direction and vestibularly perceived acceleration in the Y direction.

[0077] For example, referring to FIG1 , vehicle 10 is provided with ambient lights L1 and L2 along the Y direction. Each of ambient lights L1 and L2 includes multiple light-emitting units distributed along the Y direction. Assuming vehicle 10 is accelerating forward at an increasing rate, vehicle 10 can display a running light pattern based on ambient lights L1 and L2, with the speed of the running light indicating changes in acceleration.

[0078] For example, taking the ambient light L1 as an example, FIG2 shows a schematic diagram of the ambient light L1 displaying a flowing light. Referring to FIG2 , 10 light-emitting units in the ambient light L1 are illuminated, and every dt time period, one light-emitting unit at the tail end (Y+ direction) of the 10 light-emitting units is extinguished, and one light-emitting unit is added at the head end (Y- direction) of the 10 light-emitting units. In this way, the ambient light L1 displays an effect of 10 light-emitting units flowing toward the tail end (Y- direction) of the vehicle 10 (i.e., a flowing light effect), and the speed of the flowing light is D / dt, and the speed of the flow is negatively correlated with dt, that is, the smaller dt is, the faster the flow speed is, where D is the distance between adjacent light-emitting units.

[0079] The vehicle 10 accelerates forward at an increasing acceleration. The vehicle 10 can adjust the above-mentioned dt based on the magnitude of the acceleration of the vehicle 10, thereby adjusting the speed of the water flowing in the running light. For example, in the process of increasing the acceleration of the vehicle 10, the vehicle 10 can gradually reduce the value of dt, thereby increasing the speed of the water flowing in the running light displayed by the ambient light L1. In this way, the passenger can visually perceive that the light-emitting unit on the ambient light L1 is moving backward relative to the passenger and the speed is increasing, which is equivalent to the passenger himself moving forward relative to the ambient light L1 and the speed is increasing. In this way, the acceleration information perceived by the passenger's vision is consistent with the acceleration information perceived by the passenger's vestibule (accelerating forward at an increasing acceleration), which can alleviate the passenger's motion sickness.

[0080] The above method can alleviate motion sickness caused by the difference between the Y-direction acceleration perceived by the visual sense and the Y-direction acceleration perceived by the vestibular sense. However, in addition to the Y-direction acceleration of the vehicle, the vestibular sense can also perceive the rate of change of the vehicle's acceleration, the angular velocity / angular acceleration of the vehicle's pitch, the angular velocity / angular acceleration of the vehicle's steering, and the vehicle's acceleration in the Z-direction. If the vestibular sense of the rate of change of acceleration, the angular velocity / angular acceleration of the vehicle's pitch, the angular velocity / angular acceleration of the vehicle's steering, and the vehicle's acceleration in the Z-direction differ from the visual sense, this can lead to a conflict between the visual and vestibular senses, causing motion sickness in the passenger.

[0081] Based on this, the present application provides a display method, in which the vehicle computer can obtain the motion information of the vehicle during driving. The motion information may include one or more of the vehicle's acceleration change rate in the Y direction, the vehicle's pitch angular velocity, the vehicle's pitch angular acceleration, the vehicle's steering angular velocity, the vehicle's steering angular acceleration, and the vehicle's acceleration in the Z direction, and display visual anti-motion sickness content that matches the vehicle's motion information through one or more display devices in the vehicle. In this way, the visual anti-motion sickness content can stimulate the passenger's self-motion illusion, so that the passenger's vision can perceive the same motion information as the vestibular perception based on the visual anti-motion sickness content, which is conducive to alleviating the passenger's motion sickness.

[0082] In some embodiments, the display device may include but is not limited to display screens in the vehicle (such as the display screen of the vehicle computer, the display screen of a vehicle-mounted tablet computer, etc.), projectors, and lamps (such as ambient lights, light bars, light strips, luminous interiors, decorative lights on the screen border, etc.).

[0083] For example, referring to FIG3A and FIG3B , the display device in the vehicle 10 may include ambient lights L1, L2, L3, L4, L5, L6, and L7, a vehicle computer CM1, an in-vehicle tablet computer PD1, a in-vehicle tablet computer PD2, and a projector P (not shown). The ambient light L3 may be located on the top of the vehicle 10 and extend along the X direction, the ambient lights L4 and L5 may be located behind the seat S1 and extend along the Z direction, the ambient lights L6 and L7 may be located behind the seat S2 and extend along the Z direction, the vehicle computer CM1 may be located at the front of the vehicle 10, the in-vehicle tablet computer PD1 may be located behind the seat S1, and the in-vehicle tablet computer PD2 may be located behind the seat S2. The projection screen P1 of the projector P may be located between the front row (the row containing seats S1 and S2) and the back row (the row containing seats S3 and S4), with the projection plane extending along the XZ plane. The vehicle 10 can display visual anti-sickness content based on one or more of the ambient light L1, ambient light L2, ambient light L3, ambient light L4, ambient light L5, ambient light L6, ambient light L7, the vehicle machine CM1, the vehicle tablet computer PD1, the vehicle tablet computer PD2, and the projection P.

[0084] It should be noted that the arrangement of display devices in vehicle 10 shown in Figures 3A and 3B is merely an example. In other embodiments, vehicle 10 may include more or fewer display devices, or other types of display devices, without limitation herein. For example, ambient lighting extending in the Z direction may be provided near each door of vehicle 10, ambient lighting extending in the X direction may be provided below the seats, and ambient lighting extending in the Y direction may be provided on the roof of the vehicle.

[0085] In some embodiments, changes in a type of vehicle motion information can be represented by a content feature of one dimension of the visual motion sickness prevention content. For example, changes in one dimension of the visual motion sickness prevention content feature can indicate changes in the acceleration rate, while other dimensions of the content feature can indicate other motion information. Content features may include, but are not limited to, speed of change, spatial frequency, size, color, contrast, brightness, sparseness or density, and direction of change.

[0086] For example, when the visual anti-sickness content is based on a lamp, a display screen, a projection display lamp, or a flowing light, the dimensions of the content features of the visual anti-sickness content may include at least one of the following dimensions:

[0087] The flowing speed of the running lights (as the changing speed). For example, the greater the speed at which the light-emitting units are lit or extinguished, the greater the indicated acceleration change rate. For example, during the process of the vehicle 10 accelerating in the Y+ direction with an increasing acceleration change rate, the vehicle 10 can display the running light effect shown in FIG. 2, and the time interval (such as dt shown in FIG. 2) for adjusting the light-emitting units in the ambient light L1 decreases as the acceleration change rate of the vehicle 10 increases. It should be understood that the flowing speed of the running lights can also be used to indicate the changes in other motion information, such as the acceleration, speed, etc. of the vehicle along the Y direction, which is not limited herein.

[0088] The spatial frequency of the running lights, for example, the frequency at which the combination of the lit and extinguished light-emitting units repeats within a unit viewing angle. For example, the greater the acceleration change rate of the vehicle, the greater the number of repetitions of the combination of the lit and extinguished light-emitting units in the running lights and the higher the spatial frequency. It should be understood that the spatial frequency in the running lights can also be used to indicate the changes in other motion information, such as the acceleration, speed, etc. of the vehicle along the Y direction, which is not limited herein.

[0089] In some embodiments, a bright-dark grating combination composed of a lit light-emitting unit and an extinguished light-emitting unit may include N (N>2) light-emitting units, where, among the N light-emitting units, the first M (1≤M<N) light-emitting units are lit and the last N-M light-emitting units are extinguished, or the first M light-emitting units among the N light-emitting units are extinguished and the last N-M light-emitting units are lit. For example, assuming that there are 32 light-emitting units within a unit viewing angle, if the first 16 light-emitting units are lit and the 17th to 32nd light-emitting units are extinguished, then this viewing angle includes 1 bright-dark grating combination with a spatial frequency of 1, where the first 16 light-emitting units correspond to the bright grating and the 17th to 32nd light-emitting units correspond to the dark grating. Another example, if the first 8 light-emitting units are lit, the 9th to 16th light-emitting units are extinguished, the 17th to 24th light-emitting units are lit, and the 25th to 32nd light-emitting units are extinguished within this viewing angle, then there are 2 bright-dark grating combinations in this ambient light with a spatial frequency of 2, where: the first 16 light-emitting units form one bright-dark grating combination and the 17th to 32nd light-emitting units form one bright-dark grating combination.

[0090] The brightness of the lit light-emitting units. For example, the higher the luminous brightness of the light-emitting unit, the greater the indicated acceleration change rate. For example, assuming that the vehicle 10 is accelerating in the Y+ direction with an increasing acceleration change rate, the vehicle 10 can indicate the change in the acceleration change rate through the change in the luminous brightness of the light-emitting units in the ambient light L1. Referring to FIG. 4A, as the acceleration change rate of the vehicle 10 successively changes from da 1-y+ to da 2-y+ and from da 2-y+ to da 3-y+ and from da3-y+ Increase to da 4-y+ , the brightness of the light-emitting unit in the ambient light L1 gradually increases. It should be understood that the brightness of the light-emitting unit can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or speed in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration in the Z direction, the angular velocity of the vehicle's steering, and the angular acceleration of the vehicle's steering, without limitation here.

[0091] The color of the luminous unit. For example, the darker the color of the luminous unit, the greater the rate of change of acceleration indicated. It should be understood that the color of the luminous unit can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or speed in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration of the vehicle in the Z direction, the angular velocity of the vehicle's steering, the angular acceleration of the vehicle's steering, etc., without limitation herein.

[0092] The density of the emitting light-emitting units, such as the intervals between the emitting light-emitting units, etc. For example, the smaller the number of extinguished light-emitting units in the intervals between the emitting light-emitting units within a certain range (i.e., the higher the density of the light-emitting units), the greater the indicated acceleration change rate. For example, referring to FIG4B , taking the acceleration change rate of the vehicle 10 along the Y+ direction as an example, when the acceleration change rate of the vehicle 10 along the Y+ direction is less than da 1-y+ In the case of the ambient light L1, all the light-emitting units are extinguished; when the acceleration change rate of the vehicle 10 along the Y+ direction is greater than or equal to da 1-y+ and less than da 2-y+ In the case of the ambient light L1, one light emitting unit emits light every four light emitting units; when the acceleration change rate of the vehicle 10 along the Y+ direction is greater than or equal to da 2-y+ and less than da 3-y+ In the case of the ambient light L1, one light emitting unit emits light every three light emitting units; when the acceleration change rate of the vehicle 10 along the Y+ direction is greater than or equal to da 3-y+ and less than da 4-y+ In the case of the ambient light L1, one light emitting unit emits light every two light emitting units; when the acceleration change rate of the vehicle 10 along the Y+ direction is greater than or equal to da 4-y+ In this case, every other light-emitting unit in the ambient light L1 emits light. It should be understood that the density of the illuminated light-emitting units can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or speed in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration in the Z direction, the angular velocity of the vehicle's steering, and the angular acceleration of the vehicle's steering, without limitation here.

[0093] The flashing frequency of the luminous light-emitting unit. For example, the greater the flashing frequency of the luminous light-emitting unit, the greater the indicated acceleration change rate. It should be understood that the flashing frequency of the luminous light-emitting unit can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration in the Y direction, speed, angular velocity of vehicle pitch, angular acceleration of vehicle pitch, acceleration of vehicle in the Z direction, angular velocity of vehicle steering, angular acceleration of vehicle steering, etc., without limitation here.

[0094] For example, when the visual anti-sickness content is a pattern based on a display screen or a projection display, the dimensions of the content features of the visual anti-sickness content may include at least one of the following dimensions:

[0095] The rate of change of the pattern, such as flow velocity, expansion velocity, contraction velocity, rotational velocity, etc. For example, the greater the rate of change of the pattern, the greater the rate of change of acceleration indicated. It should be understood that the rate of change of the pattern can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or velocity in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration of the vehicle in the Z direction, the angular velocity of the vehicle's steering, the angular acceleration of the vehicle's steering, etc., without limitation herein.

[0096] The brightness of the pattern. For example, a higher brightness indicates a greater rate of acceleration change. It should be understood that the rate of change of the pattern can also be used to indicate changes in other motion information, such as changes in the vehicle's Y-axis acceleration, velocity, pitch angular velocity, pitch angular acceleration, Z-axis acceleration, steering angular velocity, steering angular acceleration, etc., without limitation herein.

[0097] The color of the pattern. For example, the darker the color of the pattern, the greater the rate of change of acceleration indicated. It should be understood that the color of the pattern can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or speed in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration in the Z direction, the angular velocity of the vehicle's steering, the angular acceleration of the vehicle's steering, etc., without limitation herein.

[0098] The density of the pattern. For example, the higher the density of the pattern, the greater the rate of change of acceleration indicated. It should be understood that the density of the pattern can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or speed in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration in the Z direction, the angular velocity of the vehicle's steering, the angular acceleration of the vehicle's steering, etc., without limitation herein.

[0099] The size of the pattern. For example, the larger the size of the pattern, the greater the rate of change of acceleration indicated. It should be understood that the rate of change of the pattern size can also be used to indicate changes in other motion information, such as changes in the vehicle's acceleration or speed in the Y direction, the angular velocity of the vehicle's pitch, the angular acceleration of the vehicle's pitch, the acceleration of the vehicle in the Z direction, the angular velocity of the vehicle's steering, the angular acceleration of the vehicle's steering, etc., without limitation herein.

[0100] The spatial frequency of the pattern. For example, a higher spatial frequency of the pattern indicates a greater rate of change in acceleration. It should be understood that the spatial frequency of the pattern can also be used to indicate changes in other motion information, such as changes in the vehicle's Y-axis acceleration, velocity, pitch angular velocity, pitch angular acceleration, Z-axis acceleration, steering angular velocity, and steering angular acceleration, without limitation.

[0101] In some embodiments, the visual anti-sickness content in the form of a pattern can include a cube, a flat-screen block, a stone, a sphere, horizontal and vertical lines, a wireframe, a combination of lines, particles, etc., or a combination of the above patterns or shapes. For example, referring to Figure 4C, the visual anti-sickness content can be vertical lines, a wireframe, particles, or a combination of multiple patterns.

[0102] In some embodiments, the visual disorientation content displayed by the display device and the normal display content displayed by the display device can be displayed in different areas of the display device, and the visual disorientation content can also be displayed as a layer over the normal display content. For example, referring to FIG4D , the vehicle 10 can display normal display content in the middle portion of the display area of ​​the vehicle computer CM1, the vehicle-mounted tablet computer PD1, the vehicle-mounted tablet computer PD2, and the projector P, and visual disorientation content in the peripheral portion. For another example, referring to FIG4E , the vehicle 10 can display normal display content in the entire display area of ​​the vehicle computer CM1, the vehicle-mounted tablet computer PD1, the vehicle-mounted tablet computer PD2, and the projector P, with the visual disorientation content displayed as a layer overlaid on top of the normal display content.

[0103] In some embodiments, the visual anti-sickness content may also be other forms of content, and the visual anti-sickness content may also include content features of other dimensions, which is not limited in the embodiments of the present application.

[0104] In some embodiments, the vehicle may select content features of corresponding dimensions from the above dimensions to indicate motion information based on the number of categories of motion information. For example, assuming that the motion information includes the vehicle's acceleration in the Y direction and the rate of change of the vehicle's acceleration in the Y direction, the vehicle may indicate the vehicle's acceleration in the Y direction by the speed of the water flowing along the Y direction of the flowing lights, and may indicate the vehicle's acceleration in the Y direction by the color or brightness of the water flowing along the Y direction, or the density of the light-emitting units, or the flashing frequency of the light-emitting units.

[0105] In some embodiments, the acceleration rate of change may include the acceleration rate of change in one or more directions, such as the acceleration rate of change in the X direction, the acceleration rate of change in the Y direction, the acceleration rate of change in the Z direction, etc. Accordingly, the vehicle may indicate the acceleration rate of change in the X direction, the acceleration rate of change in the Y direction, and the acceleration rate of change in the Z direction through visual anti-sickness content displayed on the same or different display devices.

[0106] In some embodiments, the visual anti-sickness content displayed by a display device can be used to indicate motion information in one or more directions.

[0107] For example, the visual motion sickness prevention content displayed by a display device extending in the X direction can be used to indicate motion information such as speed in the X direction, acceleration in the X direction, rate of change of acceleration in the X direction, angular velocity of the turn, and angular acceleration of the turn; the visual motion sickness prevention content displayed by a display device extending in the Y direction can be used to indicate motion information such as speed in the Y direction, acceleration in the Y direction, rate of change of acceleration in the Y direction; and the visual motion sickness prevention content displayed by a display device extending in the Z direction can be used to indicate motion information such as speed in the Z direction, acceleration in the Z direction, rate of change of acceleration in the Z direction, angular velocity of pitch, and angular acceleration of pitch. For another example, a display device capable of displaying two-dimensional or three-dimensional information (e.g., a display screen or projector) can be used to display visual motion sickness prevention content indicating speed, acceleration, angular velocity, rate of change of acceleration, and angular acceleration in one or more directions.

[0108] For example, take the acceleration change rate as an example:

[0109] The visual anti-sickness content displayed by the lamps extending along a certain direction can be used to indicate the rate of change of acceleration in that direction, or the component of the rate of change of the vehicle's synthetic acceleration in that direction. For example, the light-emitting units of the aforementioned ambient light L1 and ambient light L2 are distributed along the Y direction, and the visual anti-sickness content displayed by the ambient light L1 and ambient light L2 can be used to indicate the rate of change of acceleration of the vehicle 10 along the Y direction. For another example, the light-emitting units of the aforementioned ambient light L4, ambient light L5, ambient light L6, and ambient light L7 are distributed along the Z direction, and the visual anti-sickness content displayed by the ambient light L4, ambient light L5, ambient light L6, and ambient light L7 can be used to indicate the rate of change of acceleration of the vehicle 10 along the Z direction. For another example, the light-emitting units of the aforementioned ambient light L3 are distributed along the X direction, and the visual anti-sickness content displayed by the ambient light L3 can be used to indicate the rate of change of acceleration of the vehicle 10 along the X direction.

[0110] The visual anti-sickness content displayed on the display screen or projection can be used to indicate the acceleration rate of the vehicle 10 in one or more directions within the display plane of the display screen (or the projection plane of the projector), and / or the acceleration rate perpendicular to the display plane and / or projection plane. For example, if the display plane of the vehicle computer CM1, the display plane of the vehicle-mounted tablet computer PD1, the display plane of the vehicle-mounted tablet computer PD2, and the projection plane of the projection P1 extend along the XZ plane, they can be used to display the acceleration rate in one or more of the X, Y, and Z directions.

[0111] In some embodiments, the vehicle computer can also obtain other vehicle motion information, such as speed and acceleration, and indicate changes in this motion information based on changes in one or more other content features within the visual anti-sickness content, other than the feature indicating the rate of change of acceleration. This can improve the consistency between the motion information perceived by the passenger's vision and the motion information perceived by the passenger's vestibule, further alleviating motion sickness.

[0112] In some embodiments, the vehicle computer can display visual anti-motion sickness content corresponding to the motion information and play corresponding audio anti-motion sickness content when the vehicle's motion information meets the corresponding anti-motion sickness conditions. For example, the anti-motion sickness conditions corresponding to different types of motion information can be thresholds reached by the motion information of that type, such as thresholds that may cause motion sickness in passengers. Exemplarily, in some embodiments, the anti-motion sickness conditions may include at least one of the following conditions:

[0113] The absolute value of the acceleration is greater than the first value. In some embodiments, the first value may be the same or different for acceleration and deceleration scenarios. For example, for acceleration scenarios, the first value may be greater than or equal to 0.2 m / s 2 Any value, for example, the first value is 0.2m / s 2 In the case of vehicle acceleration greater than 0.2m / s 2 The anti-motion sickness condition corresponding to the acceleration is met; for the deceleration scenario, the first value can be greater than or equal to 0.3m / s 2 Any value, for example, the first value is 0.3m / s 2 In this case, the vehicle acceleration is less than -0.3m / s 2 Then the anti-motion sickness condition corresponding to the acceleration is met.

[0114] The absolute value of the acceleration change rate is greater than the second value. In some embodiments, for the acceleration increasing and the acceleration decreasing scenes, the second value can be the same or different. For example, for the acceleration increasing and the acceleration decreasing scenes, the second value can be set to be greater than or equal to 0.2m / s 3For example, the second value is 0.2m / s 3 In the case of the vehicle's acceleration rate of change is greater than 0.2m / s 3 or less than -0.2m / s 3 For example, for a scene with increasing acceleration, the second value may be set to be greater than or equal to 0.25 m / s. 3 For example, the second value is 0.25m / s 2 In the case of the vehicle's acceleration rate of change is greater than 0.25m / s 3 When the acceleration rate is reduced, the anti-motion sickness condition corresponding to the acceleration change rate is met; for the scene where the acceleration decreases, the second value can be set to be greater than or equal to 0.2m / s 3 For example, the second value is 0.2m / s 2 In the case of the vehicle's acceleration change rate is less than -0.2m / s 3 The anti-motion sickness condition corresponding to the acceleration change rate is met.

[0115] The angular velocity is greater than a third value. For example, the third value may be any value greater than 0.3 degrees per second (° / s).

[0116] The angular acceleration is greater than a fourth value. For example, the fourth value may be greater than 0.03 degrees per second squared (° / s 2 ) can be any value.

[0117] In some embodiments, the first value, the second value, the third value, and the fourth value may be theoretical values, experimental values, or empirical values.

[0118] In some embodiments, the first value, the second value, the third value, and the fourth value may be used to indicate a threshold value at which a passenger is susceptible to motion sickness.

[0119] In some embodiments, the first, second, third, and fourth values ​​can be dynamically configured based on different passengers. For example, if a passenger is prone to motion sickness, the first, second, third, and fourth values ​​can be lowered; if a passenger is less prone to motion sickness, the first, second, third, and fourth values ​​can be raised.

[0120] It should be noted that, corresponding to accelerations, acceleration change rates, angular velocities or angular accelerations in different directions, the corresponding first values, second values, third values ​​or fourth values ​​may be different.

[0121] In some embodiments, the vehicle computer can first determine the passengers who need motion sickness prevention (hereinafter referred to as target passengers, who will experience motion sickness), and display visual motion sickness prevention content through the portion of the display device in the vehicle corresponding to the target passengers. For example, the vehicle can display visual motion sickness prevention content based on a display device (or a portion of a display device) that is in the field of view of the target passenger (or the field of view that the target passenger can see when moving) and is not in the field of view of non-target passengers (or in the field of view of non-target passengers but not likely to cause motion sickness in non-target passengers). In this way, the visual motion sickness prevention content can be prevented from affecting the driver or other passengers who do not need motion sickness prevention.

[0122] For example, in the scenario shown in Figure 3A, if the passenger in seat S3 is the target passenger and the passenger in seat S4 is not, the vehicle 10 can display motion sickness prevention content based on one or more of the following: ambient light L1, onboard tablet computer PD1, ambient light L4, ambient light L5, the left side of ambient light L3, and the left side of projection screen P1, while omitting the display of motion sickness prevention content on ambient light L2, ambient light L6, ambient light L7, onboard tablet computer PD2, the right side of ambient light L3, the right side of projection screen P1, and vehicle computer CM1. This alleviates motion sickness for the target passenger in seat S3 while minimizing the risk of motion sickness.

[0123] In some embodiments, the target passenger can be determined through interaction between the driver or passenger and the vehicle 10, or automatically by the vehicle 10 based on operational logic. For example, a switch for activating the motion sickness prevention function can be provided in the vehicle 10, and the passenger or driver can use this switch to turn the motion sickness prevention function on or off for one or more seats. Upon detecting that the motion sickness prevention function for a particular seat is activated, the vehicle 10 can determine that the passenger in that seat is the target passenger. For another example, the vehicle computer CM1, the onboard tablet computer PD1, the onboard tablet computer PD2, or a passenger's electronic device in the vehicle 10 can be installed with an application that interacts with the vehicle 10. The passenger or driver can interact with the vehicle 10 based on this application, select whether they are prone to motion sickness, and select whether the motion sickness prevention function for their seat is to be turned on or off. For another example, the vehicle 10 can store characteristics (e.g., biometrics) of passengers for whom the motion sickness prevention function is to be activated. The vehicle 10 can then acquire these characteristics using sensors within the vehicle 10 (e.g., biometric sensors, cameras, etc.) and identify a passenger as the target passenger if the acquired characteristics match a stored set of characteristics.

[0124] In some embodiments, the vehicle computer can also play corresponding audio content to prevent motion sickness, and use changes in one or more audio features of the audio content to indicate changes in the vehicle's acceleration rate (and / or other vehicle motion information). This can ensure that the passenger's auditory, visual, and vestibular motion information remains consistent, further alleviating motion sickness.

[0125] In some embodiments, the audio features of the audio anti-sickness content may include, but are not limited to, frequency, loudness, timbre, sound and image movement speed, rhythm, and tempo. For example, a vehicle can utilize spatial audio stereo to simulate the location of a sound source, i.e., sound and image. The direction of motion of the vehicle can be indicated by a sound and image moving in the opposite direction of the vehicle's motion. Information on the intensity of the vehicle's motion (e.g., speed, acceleration, rate of change of acceleration, angular velocity, angular acceleration, etc.) can be indicated by the loudness, frequency, timbre, and tempo of the sound. For example, the sound and image position can be located in front of the passenger, and a sound message with a gradually faster tempo can prompt the vehicle to accelerate forward, or a sound message with a gradually slower tempo can prompt the vehicle to decelerate forward.

[0126] In some embodiments, the vehicle's motion information can be calculated in real time based on information collected by detection devices such as sensors installed in the vehicle.

[0127] In some embodiments, the vehicle's motion information can be predicted based on historical motion information. In this case, the visual motion sickness prevention content displayed by the vehicle can be ahead of the vehicle's actual motion state. For example, if the vehicle predicts motion information at time T1, the visual motion sickness prevention content corresponding to the predicted motion information at time T1 can be displayed at time T2 (or audio motion sickness prevention content can be played simultaneously) before T1. In this way, passengers can visually predict upcoming changes in motion state, which can help further alleviate motion sickness.

[0128] The technical solution of this application is introduced below in combination with the content features of the aforementioned visual anti-dizziness content.

[0129] In some embodiments, vehicle 10 can use running lights flowing in the X direction to indicate motion information when the vehicle is turning. For example, the speed of the running lights can indicate the angular velocity of the vehicle's turn, with a greater speed indicating a greater angular velocity. The number of light-emitting units in the running lights can indicate angular acceleration, with a greater number of light-emitting units indicating a greater angular acceleration. The direction of the turn can be indicated by the direction of the running lights, with the direction of the running lights being opposite to the direction of the vehicle's turn.

[0130] Exemplarily, FIG5 shows a schematic diagram of visual anti-sickness content corresponding to turning motion information.

[0131] Referring to Figure 5, assuming that the vehicle is moving at an angular velocity ω 1-z- When turning right, the vehicle 10 can display a leftward flowing water light effect on the ambient light L3, and the time interval for the vehicle 10 to switch the light emitting unit in the ambient light L3 is dt1, which is equivalent to the water flow speed of the water light being the distance D between the light emitting units divided by dt1. 1-z- In the case of the ambient light L3, the flowing light can be a flowing light with one light emitting unit; when the angular acceleration of the vehicle 10 is greater than α 1-z- α 2-z- In this case, the flowing light displayed by the atmosphere light L3 can be a flowing light with two light-emitting units flowing.

[0132] Continuing to refer to FIG5, assuming that the vehicle is larger than ω 1-z- Angular velocity ω 2-z- When turning right, the vehicle 10 can display a water-flowing effect on the ambient light L3, and the time interval for the vehicle 10 to switch the light-emitting unit in the ambient light L3 is dt2 (dt1>dt2), which is equivalent to the water flow speed of the water-flowing light increasing by D divided by dt2. 1-z- In the case of the ambient light L3, the flowing light displayed can be a flowing light with one light-emitting unit; when the angular acceleration of the vehicle 10 is α 2-z- In this case, the flowing light displayed by the atmosphere light L3 can be a flowing light with two light-emitting units flowing.

[0133] In some embodiments, the vehicle 10 can indicate the vehicle's pitch motion information in the Z direction by means of flowing lights along the Z direction, such as the vehicle's pitch angular velocity, the vehicle's pitch angular acceleration, the vehicle's acceleration in the Z direction, the vehicle's acceleration change rate in the Z direction, etc.

[0134] For example, the vehicle 10 can indicate the angular velocity of the vehicle's pitch by the flow speed of the running light. The greater the flow speed, the greater the angular velocity; the angular acceleration of the vehicle's pitch can be indicated by the number of extinguished light-emitting units between the light-emitting units of the running light. The greater the number of intervals, the smaller the angular acceleration; the direction of pitch can be indicated by the flow direction of the running light. The flow direction of the running light is opposite to the pitch direction of the vehicle 10. For example, if the angle between the vehicle 10 and the horizontal plane decreases, the running light flows in the Z- direction, or if the angle between the vehicle 10 and the horizontal plane increases, the running light flows in the Z+ direction.

[0135] Exemplarily, FIG6A shows a schematic diagram of visual anti-sickness content corresponding to motion information in the Z direction.

[0136] 6A , assuming that the vehicle is traveling on a road with a varying slope, the vehicle has an angular velocity ω in the X-direction. 1-x- If the vehicle 10 rotates and the angle between the vehicle 10 and the horizontal plane gradually decreases, the vehicle 10 can display a downward flowing water light effect on the ambient light L4 (and / or ambient light L5, and / or ambient light L6, and / or ambient light L7), and the time interval for the vehicle 10 to switch the light-emitting unit in the ambient light L4 is dt1, which is equivalent to the water flow speed of the water light being the distance D between adjacent light-emitting units divided by dt1. 1-x- In the case of the ambient light L4, the flowing light can be displayed by 5 adjacent light-emitting units; when the angular acceleration of the vehicle 10 is less than α 1-x- α 2-x- In this case, the flowing light displayed by the atmosphere light L4 may be that the first, third and fifth light-emitting units among the five adjacent light-emitting units are illuminated, that is, there is one extinguished light-emitting unit between two adjacent illuminated light-emitting units.

[0137] 6A, when the vehicle is in the X-direction and is greater than ω 1-x- Angular velocity ω 2-x- The vehicle 10 rotates, and the angle between the vehicle 10 and the horizontal plane gradually decreases. The vehicle 10 can display a downward flowing water light effect on the ambient light L4 (and / or ambient light L5, and / or ambient light L6, and / or ambient light L7), and the time interval for the vehicle 10 to switch the display unit of the light-emitting unit in the ambient light L4 is dt2 (dt2>dt1), which is equivalent to the water flow speed of the water light being reduced to D divided by dt2. When the angular acceleration of the vehicle 10 pitching is α 1-x- In the case of the ambient light L4, the flowing light can be displayed by 5 adjacent light-emitting units; when the angular acceleration of the vehicle 10 is less than α 1-x- α 2-x- In this case, the flowing light displayed by the atmosphere light L4 may be that the first, third and fifth light-emitting units among the five adjacent light-emitting units are illuminated, that is, there is one extinguished light-emitting unit between two adjacent illuminated light-emitting units.

[0138] For another example, the vehicle 10 can use the number of extinguished light-emitting units in the running light to indicate the acceleration in the Z direction. The more intervals there are, the smaller the acceleration. The brightness of the light-emitting units in the running light can be used to indicate the rate of change of acceleration in the Z direction. The higher the brightness, the greater the rate of change of acceleration.

[0139] For example, FIG6B shows a schematic diagram of another type of visual anti-sickness content corresponding to motion information in the Z direction.

[0140] Referring to FIG6B , assuming that the vehicle bumps upward on an uneven road, the acceleration of the vehicle in the Z+ direction is a 1-z- , the vehicle 10 can display a downward flowing water light effect on the ambient light L4 (and / or ambient light L5, and / or ambient light L6, and / or ambient light L7), and the flowing water light can be five adjacent light-emitting units. 1-z- In the case of the ambient light L4, the luminous brightness of the luminous unit can be the first brightness (the luminous unit filled with black in the figure); when the acceleration change rate of the vehicle 10 in the Z+ direction is da 2-z- (da 1-z- >da 2-z- ), the luminous brightness of the light-emitting unit of the ambient light L4 can be a second brightness lower than the first brightness (the light-emitting unit filled with gray in the figure).

[0141] 6B, when the vehicle's acceleration in the Z+ direction is less than a 1-z- a 2-z- In the case of the downward flowing water light displayed by the ambient light L4, the first, third and fifth light-emitting units among the five adjacent light-emitting units may be illuminated, that is, there is one extinguished light-emitting unit between two adjacent illuminated light-emitting units. 1-z- In the case of the ambient light L4, the luminous brightness of the luminous unit can be the first brightness (the luminous unit filled with black in the figure); when the acceleration change rate of the vehicle 10 in the Z+ direction is da 2-z- (da 1-z- >da 2-z- ), the luminous brightness of the light-emitting unit of the ambient light L4 can be a second brightness lower than the second brightness (the light-emitting unit filled with gray in the figure).

[0142] In some embodiments, the vehicle 10 may indicate the vehicle's motion information in the Y direction, such as the vehicle's speed, acceleration, acceleration change rate, etc. in the Y direction, by means of running lights flowing along the Y direction.

[0143] For example, the vehicle 10 can indicate the direction of vehicle movement by the direction of water flowing in the Y direction of the running light, and the direction of water flow is opposite to the direction of vehicle movement; the speed of the vehicle in the Y direction can be indicated by the speed of the water flowing in the running light, and the greater the speed of the water flow, the greater the speed of the vehicle in the Y direction; the acceleration of the vehicle 10 in the Y direction can be indicated by the number of light-emitting units emitted by the running light, and the more light-emitting units there are, the greater the acceleration of the vehicle in the Y direction; the acceleration change rate in the Y direction can be indicated by the number of light-emitting units that are extinguished in the intervals between the light-emitting units of the running light, and the greater the number of intervals, the smaller the acceleration change rate of the vehicle 10 in the Y direction.

[0144] Exemplarily, FIG. 7 shows a schematic diagram of visual anti-motion sickness content corresponding to motion information in the Y direction.

[0145] Referring to FIG. 7, when the vehicle travels in the Y+ direction at a speed v 1-y+ , acceleration a 1-y+ , acceleration change rate da 1-y+ , the vehicle 10 can display a running light effect in which 10 illuminated light-emitting units flow in the Y- direction on the ambient light L1 (and / or ambient light L2), and the running speed of the running light is the distance D between adjacent light-emitting units divided by dt1. When the speed of the vehicle increases from v 1-y+ to v 2-y+ , the running speed of the running light can be switched to D / dt2, where dt2 < dt1; when the acceleration of the vehicle decreases from a 1-y+ to a 2-y+ , the number of light-emitting units of the running light emitting light is reduced from 10 to 7. When the acceleration change rate of the vehicle decreases from da 1-y+ to da 2-y+ , the number of extinguished light-emitting units in the interval between the light-emitting units of the running light emitting light increases from 0 to 2.

[0146] It should be understood that the forms of the visual anti-motion sickness content shown in FIGS. 5 to 7 are only examples. In other embodiments, the dimensions indicating the content characteristics of different motion information can be adjusted, the motion information indicated by the visual anti-motion sickness content can also be increased or decreased, and each motion information can also be indicated by other dimensions, which are not limited herein.

[0147] FIG. 8 shows a schematic flowchart of a display method according to some embodiments of the present application.

[0148] As shown in FIG. 8, the execution subject of this process can be the vehicle 10, such as the vehicle-mounted computer, controller or other devices / modules in the vehicle 10. As shown in FIG. 8, this process includes the following steps:

[0149] S801, determine the display range according to the passenger information of the passenger and the information of the display device.

[0150] The vehicle 10 can determine the display range of the visual anti-motion sickness content according to the passenger information of the passengers in the vehicle and the information of the display device in the vehicle.

[0151] In some embodiments, the passenger information may include the position of the passenger in the vehicle, the gaze direction of the passenger, the binocular position of the passenger, etc. The vehicle 10 can determine the field of view ranges of the target passengers and non-target passengers in the vehicle based on the passenger information of the passengers.

[0152] In some embodiments, the information of the display device in the vehicle may include the location where the display device is set in the vehicle, the current display task of the display device, etc.

[0153] For example, the vehicle 10 can determine the display range for displaying motion sickness prevention content based on the field of view of the target passenger and non-target passengers, the position of the display device in the vehicle, and the current display task of the display device. For example, the vehicle 10 can determine the display range of the visual motion sickness prevention content to be a display device (or a portion of the display area of ​​the display device) that is within the field of view of the target passenger (or larger than the field of view of the target passenger) and not within the field of view of the non-target passenger (or within the field of view of the non-target passenger but not easily noticed by the non-target passenger). In this way, the motion sickness of the target passenger can be alleviated without affecting non-target passengers.

[0154] For example, referring to Figures 3A and 9 , assume that the passenger in seat S3 is the target passenger and the passenger in seat S4 is the non-target passenger. The target passenger's field of view is D1, and the non-target passenger's field of view is D2. As shown in Figure 9 , the display device (or display area of ​​the display device) within the target passenger's field of view includes: the front portion of ambient light L1, the left portion of ambient light L3, ambient light L4, ambient light L5, ambient light L6, the in-vehicle tablet computer PD1, and the left area of ​​in-vehicle tablet computer PD2. The display device (or display area of ​​the display device) within the non-target passenger's field of view includes: the front portion of ambient light L2, the right portion of ambient light L3, ambient light L5, ambient light L6, ambient light L7, the right portion of in-vehicle tablet computer PD1, and in-vehicle tablet computer PD2. Vehicle 10 can define the display area of ​​ambient light L1 within area D1, the display area of ​​ambient light L4, the in-vehicle tablet computer PD1, and the display area of ​​ambient light L3 within area D1 as the display area.

[0155] In some embodiments, corresponding to the scenario shown in FIG9 , if the in-vehicle tablet computer PD1 has other display tasks, such as displaying video content selected by the target passenger, the visual motion sickness prevention content may not be displayed on the tablet computer PD1, or the visual motion sickness prevention content may be displayed at the edge of the tablet computer PD1 display area, or the visual motion sickness prevention content may be displayed as an overlay on the display content of other tasks displayed on the tablet computer PD1. In this way, the visual motion sickness prevention content can be prevented from affecting other services within the vehicle 10.

[0156] In some embodiments, corresponding to the scenario shown in FIG9 , although ambient light L5 is within the non-target passenger's field of view, it is at the edge of the non-target passenger's field of view and is unlikely to attract the non-target passenger's attention. Vehicle 10 may also set ambient light L5 within the display range. This increases the display range for displaying visual motion sickness prevention content, making it easier to stimulate the target passenger's self-motion illusion, thereby further alleviating the target passenger's motion sickness.

[0157] In some embodiments, corresponding to the scenario shown in FIG9 , although the rear portion of ambient light L1 is not within the target passenger's field of view (i.e., the portion of ambient light L1 is not within area D1), the target passenger may still notice the rear portion of ambient light L1 if they move (e.g., sideways, looking back, or shifting position). Vehicle 10 can set the entire display area of ​​ambient light L1 within the display range. This increases the display range for displaying visual motion sickness prevention content, making it easier to stimulate the target passenger's self-motion illusion, thereby more effectively alleviating the target passenger's motion sickness.

[0158] In some embodiments, if all passengers in the vehicle are target passengers, the vehicle 10 may set all display devices in the vehicle 10 that can be used to display visual anti-sickness content within the display range.

[0159] In some embodiments, the information of the display device also includes the adjustable range of content characteristics of the visual anti-sickness content that the display device can display, such as the adjustable range of brightness, contrast, spatial frequency, flow speed, color, type of visual anti-sickness content pattern, etc., as well as the distance and direction relative to the passengers.

[0160] In some embodiments, when determining the display range, the vehicle 10 may also obtain environmental information within the vehicle 10, such as the placement of items in the vehicle, the extent to which the items obstruct the target passenger's field of view, etc. In this way, the vehicle 10 may not place display devices (or portions of display areas of display devices) obstructed by items within the display range.

[0161] In some embodiments, the display devices within vehicle 10 can be further categorized based on the direction in which the displayed content extends (or the direction of the motion information that can be indicated). For example, display devices can be categorized as display devices extending along the X-axis, where the portion of the display device can display motion information in the X-direction; display devices extending along the Y-axis, where the portion of the display device can display motion information in the Y-direction; and display devices extending along the Z-axis, where the portion of the display device can display motion information in the Z-direction. When determining the display range, vehicle 10 can select at least one display device (or display area of ​​a display device) from each category.

[0162] In some embodiments, the target passenger can be determined by the driver or passenger interacting with the vehicle 10, or it can be determined automatically by the vehicle 10 based on operating logic. For example, a switch for activating the anti-motion sickness function can be set in the vehicle 10, and the passenger or driver can turn on or off the anti-motion sickness function for one or more seats based on the switch. After the anti-motion sickness function corresponding to a certain seat is turned on, the passenger in that seat can be the target passenger. For another example, the vehicle computer CM1, the on-board tablet computer PD1, the on-board tablet computer PD2, or the passenger's electronic device in the vehicle 10 can be installed with an application that interacts with the vehicle 10, and the passenger or driver can interact with the vehicle 10 based on the application to turn on or off the anti-motion sickness function corresponding to each seat. For another example, the vehicle 10 can store the characteristics of the passengers who need to activate the anti-motion sickness function (such as biometric characteristics, etc.), and the vehicle 10 can obtain the characteristics of the passengers through sensors inside the vehicle 10 (such as biometric sensors, cameras, etc.) to determine the target passenger.

[0163] In other embodiments, the target passenger may be determined by other methods, which are not limited here.

[0164] S802: Acquire vehicle motion information.

[0165] Exemplarily, the vehicle 10 may obtain motion information of the vehicle 10 , which may include at least one of the following information: velocity, acceleration, acceleration change rate, angular velocity, and angular acceleration. The velocity may include one or more of the velocity in the X direction, the velocity in the Y direction, and the velocity in the Z direction, or may be the composite velocity of the vehicle 10 ; the acceleration may include one or more of the acceleration in the X direction, the acceleration in the Y direction, and the acceleration in the Z direction, or may be the composite acceleration of the vehicle 10 ; the acceleration change rate may include one or more of the acceleration change rate in the X direction, the acceleration change rate in the Y direction, and the acceleration change rate in the Z direction; the angular velocity may include one or more of the angular velocity in the X direction (as the angular velocity of pitch), the angular velocity in the Y direction, and the angular velocity in the Z direction (as the angular velocity of steering); and the angular acceleration may include one or more of the angular acceleration corresponding to the angular velocity in the X direction (as the angular acceleration of pitch), the angular acceleration in the Y direction, and the angular acceleration in the Z direction (as the angular acceleration of steering).

[0166] In some embodiments, the motion information of the vehicle 10 may be directly acquired based on sensors or other detection devices provided in the vehicle 10 , or may be calculated based on current data and historical data of the sensors in the vehicle 10 .

[0167] In some embodiments, the motion information of the vehicle 10 may also be predicted based on historical motion information of the vehicle 10. For example, the vehicle 10 may use a model or algorithm to predict the motion information of the vehicle 10 at a future moment based on road conditions, vehicle information of the vehicle 10 (e.g., pedal opening and closing angle, steering wheel angle, speed, time, vehicle mass), and historical motion information of the vehicle 10.

[0168] S803: Display visual anti-sickness content corresponding to the motion information.

[0169] For example, the vehicle 10 can select a display device within the display range that corresponds to the motion information to display the corresponding visual anti-sickness content based on the acquired motion information. For example, the speed along the X direction, the acceleration along the X direction, the rate of change of acceleration along the X direction, the angular velocity of the steering, the angular acceleration of the steering, etc. can be displayed by a display device extending along the X direction, such as the ambient light L3, the onboard tablet computer PD1, the onboard computer PD2, the projector P, the vehicle computer CM1, etc. For another example, the speed along the Y direction, the acceleration along the Y direction, the rate of change of acceleration along the Y direction, etc. can be displayed by a display device extending along the Y direction, such as the aforementioned ambient light L1, ambient light L2, etc. For another example, the speed along the Z direction, the acceleration along the Z direction, the rate of change of acceleration along the Z direction, the angular velocity of pitch, the angular acceleration of pitch, etc. can be displayed by a display device extending along the Z direction to display the corresponding visual anti-dizziness content, such as the atmosphere light L4, the atmosphere light L5, the atmosphere light L6, the atmosphere light L7, the vehicle-mounted tablet computer PD1, the vehicle-mounted computer PD2, the projector P, the vehicle computer CM1, etc.

[0170] In some embodiments, a dimension of a content attribute of visual motion sickness prevention content displayed by a display device can be used to indicate motion information. The dimensions of the content attribute may include, but are not limited to, change speed, spatial frequency, size, color, contrast, brightness, sparseness or density, and change direction.

[0171] In some embodiments, the vehicle 10 may first determine whether each piece of motion information satisfies a corresponding motion sickness prevention condition and then display the corresponding visual motion sickness prevention content for the motion information that satisfies the motion sickness prevention condition. For example, after acquiring the vehicle's motion information, the vehicle 10 may determine one or more pieces of motion information that meet the motion sickness prevention condition. The vehicle 10 then selects the corresponding dimension from the content attributes of the visual motion sickness prevention content that can be displayed by the display device within the display range.

[0172] For example, assuming that the motion information includes the acceleration of the vehicle 10 in the Y direction, the acceleration change rate of the vehicle 10 in the Y direction, the pitch angular velocity of the vehicle 10, the angular velocity of the vehicle 10 turning, and the angular acceleration of the vehicle 10 turning:

[0173] When the vehicle 10 determines that the acceleration in the Y direction, the rate of change in the Y direction, and the pitch angular velocity meet the anti-motion sickness conditions, but the steering angular velocity and the steering angular acceleration do not meet the anti-motion sickness conditions, the vehicle 10 can display visual anti-motion sickness content indicating the acceleration in the Y direction and the rate of change in the Y direction on the ambient light L1 (for example, the flowing light shown in Figure 7), and display visual anti-motion sickness content indicating the pitch angular velocity on the ambient light L4, and / or the ambient light L5, and / or the on-board tablet computer PD1 (for example, the flowing light shown in Figure 6A).

[0174] When the vehicle 10 determines that the acceleration in the Y direction, the rate of change in the Y direction, and the pitch angular velocity do not meet the anti-motion sickness conditions, but the steering angular velocity and the steering angular acceleration meet the anti-motion sickness conditions, the vehicle 10 can display visual anti-motion sickness content indicating the steering angular velocity and the steering angular acceleration on the left half of the ambient light L3 (such as the flowing light shown in Figure 5).

[0175] In some embodiments, if a portion of the vehicle's motion information does not meet the anti-motion sickness condition, the visual anti-motion sickness content displayed by the vehicle 10 indicates that the content features of this portion of the motion information may be weakly prompted to the passenger or not prompted to the passenger at all; if a portion of the vehicle's motion information meets the anti-motion sickness condition, the visual anti-motion sickness content displayed by the vehicle 10 indicates that the intensity of the content features of this portion of the motion information may increase as the intensity of the motion information (e.g., velocity, acceleration, rate of change of acceleration, angular velocity, angular acceleration, etc.) increases. For example, if the change in acceleration is indicated by the speed of the water flowing through a running light, when the absolute value of the acceleration is less than or equal to a first value, the running light does not flow or moves at a speed v0; when the absolute value of the acceleration is greater than the first value, the flow speed of the running light is v1, which is greater than v0, and v1 increases as the absolute value of the acceleration increases.

[0176] In some embodiments, the range of some content attributes of the visual anti-motion sickness content displayed by the vehicle 10, such as brightness, color temperature, contrast, etc., can be determined based on the environment inside the vehicle 10, for example, it can be determined based on the lighting information inside the vehicle 10 (such as color temperature, brightness, lighting color, etc.). In the case where brightness, color temperature, and contrast are not used as dimensions to indicate motion information, the brightness, color temperature, and contrast of the visual anti-motion sickness content displayed in the vehicle 10 can be adjusted according to the brightness, color temperature, and contrast of the environment. In the case where brightness, color temperature, and contrast are used as dimensions to indicate motion information, the range of variation of the brightness, color temperature, and contrast of the visual anti-motion sickness content displayed in the vehicle 10 can be adjusted according to the brightness, color temperature, and contrast of the environment. For example, when the brightness of the internal environment of the vehicle 10 is low, the brightness of the visual anti-motion sickness content can be set within a lower range to avoid glare and other discomforts for passengers caused by excessive brightness. For another example, when the brightness of the internal environment of the vehicle 10 is high, the brightness of the visual anti-motion sickness content can be set within a higher range to avoid the inability of passengers to perceive the visual anti-motion sickness content, so as to improve the success rate of alleviating passengers' motion sickness.

[0177] In some embodiments, the direction of change of the visual motion sickness prevention content (e.g., the flow direction of a running light, the movement direction / contraction direction / expansion direction / rotation direction of a moving pattern, etc.) may be opposite to the acceleration direction, speed direction, or rotation direction of the vehicle 10. For example, if the acceleration of the vehicle 10 does not meet the motion sickness prevention conditions, the direction of change of the visual motion sickness prevention content may be opposite to the speed direction, for example, the speed of the water in the running light is opposite to the speed of the vehicle; if the acceleration of the vehicle 10 meets the motion sickness prevention conditions, the direction of change of the visual motion sickness prevention content may be opposite to the acceleration direction, for example, the speed of the water in the running light is opposite to the acceleration of the vehicle.

[0178] For example, assuming that the motion information includes the vehicle's acceleration in the Y direction and the rate of change of acceleration in the Y direction, the vehicle 10 can indicate the direction of its motion or acceleration by the direction of the water flowing in the Y direction of the running lights, where the water direction is opposite to the direction of the vehicle's motion or acceleration. The speed of the running lights can be used to indicate the vehicle's speed or acceleration in the Y direction, with the greater the water speed, the greater the vehicle's speed or acceleration in the Y direction. The rate of change of the vehicle's acceleration in the Y direction can be indicated by the spatial frequency of the running lights, with the greater the spatial frequency, the greater the rate of change of acceleration in the Y direction.

[0179] For example, if the acceleration in the Y direction or the rate of change of acceleration in the Y direction does not meet the motion sickness prevention conditions, the vehicle 10 may display a low-speed running light in the ambient light L1 (and / or ambient light L2) in the opposite direction of the vehicle's speed, or control some or all of the light-emitting units of the ambient light L1 to illuminate without running. For example, referring to Figure 10 , the vehicle 10's speed direction is Y+ and the acceleration direction is Y-:

[0180] If the acceleration in the Y direction is less than or equal to the first value and the rate of change of acceleration in the Y direction is less than or equal to the second value, the ambient light L1 can illuminate 6 adjacent light-emitting units out of every 8 light-emitting units, and turn off the other 2 adjacent light-emitting units, and flow in the Y-direction at a speed of D / dt (where D is the distance between adjacent light-emitting units).

[0181] If the acceleration in the Y direction is greater than a first value and the rate of change of acceleration in the Y direction is less than or equal to a second value, the ambient light L1 can illuminate six adjacent light-emitting units out of every eight light-emitting units, while the other two adjacent light-emitting units are off, and flow in the Y+ direction at a speed of D / dt1. Furthermore, dt can decrease as the acceleration in the Y direction increases, which is equivalent to the flow speed increasing with the increase in the acceleration in the Y direction.

[0182] If the acceleration in the Y direction is greater than a first value and the rate of change of acceleration in the Y direction is greater than or equal to a second value, the ambient light L1 may emit light in four of every six adjacent light-emitting units, while the other two adjacent light-emitting units are off, and flow in the Y+ direction at a speed of D / dt1. Furthermore, as the rate of change of acceleration in the Y direction increases, the spatial frequency of the ambient light L1 may further increase, for example, to the point where two of every three adjacent light-emitting units emit light while the other is off (or one of every two light-emitting units emits light while the other is off).

[0183] In some embodiments, the vehicle 10 may divide the intensity of the motion information into multiple intensity intervals and set an intensity of the visual anti-sickness content for each intensity interval. The vehicle 10 may control the intensity of the content attribute indicating the motion information according to the intensity of the motion information.

[0184] Exemplarily, corresponding to the acceleration change rate, the intensity interval may include 4 intensity intervals (or any other value greater than 1, not limited here): [0, first value], (first value, first acceleration change rate], (first acceleration change rate, second acceleration change rate], (second acceleration change rate, +∞):

[0185] When the content attribute indicating the acceleration change rate is the speed of change, the visual anti-sickness content intensities corresponding to the above four intensities can be the first speed, the second speed, the third speed, and the fourth speed, respectively. For example, assuming that the visual anti-sickness content is a running light: when the acceleration change rate of the vehicle 10 is less than or equal to the first value, the running light flows at the first speed; when the acceleration change rate of the vehicle 10 is greater than the first value and less than the second acceleration change rate, the running light flows at the second speed; when the acceleration change rate of the vehicle 10 is greater than the first acceleration change rate and less than the second acceleration change rate, the running light flows at the third speed; and when the acceleration change rate of the vehicle 10 is greater than the second acceleration change rate, the running light flows at the fourth speed.

[0186] In the case where the content attribute indicating the acceleration change rate is brightness, the visual anti-sickness content intensities corresponding to the above four intensities can be the first brightness, the second brightness, the third brightness, and the fourth brightness, respectively. For example, assuming that the visual anti-sickness content is a running light or a pattern: when the acceleration change rate of the vehicle 10 is less than or equal to the first value, the visual anti-sickness content is displayed at the first brightness; when the acceleration change rate of the vehicle 10 is greater than the first value and less than the second acceleration change rate, the visual anti-sickness content is displayed at the second brightness; when the acceleration change rate of the vehicle 10 is greater than the first acceleration change rate and less than the second acceleration change rate, the visual anti-sickness content is displayed at the third brightness; when the acceleration change rate of the vehicle 10 is greater than the second acceleration change rate, the visual anti-sickness content is displayed at the fourth brightness.

[0187] In the case where the content attribute indicating the acceleration change rate is spatial frequency, the visual anti-sickness content intensities corresponding to the above four intensities can be the first brightness, the second brightness, the third brightness, and the fourth brightness, respectively. For example, assuming that the visual anti-sickness content is a running light or a pattern: when the acceleration change rate of the vehicle 10 is less than or equal to the first value, the visual anti-sickness content is displayed at a first spatial frequency (for example, the frequency of the combination of the illuminated light-emitting unit and the extinguished light-emitting unit in the running light being repeated within a unit viewing angle is p1), and when the acceleration change rate of the vehicle 10 is greater than the first value and less than the second acceleration change rate, the visual anti-sickness content is displayed at a second spatial frequency (for example, the frequency of the combination of the illuminated light-emitting unit and the extinguished light-emitting unit in the running light being repeated within a unit viewing angle is p2, and p2> p1), when the acceleration change rate of the vehicle 10 is greater than the first acceleration change rate and less than the second acceleration change rate, the visual anti-sickness content is displayed at a third spatial frequency (for example, the frequency of the combination of the light-emitting units that glow and the light-emitting units that are extinguished in the flowing light within a unit viewing angle is p3, p3>p2), and when the acceleration change rate of the vehicle 10 is greater than the second acceleration change rate, the visual anti-sickness content is displayed at a fourth spatial frequency (for example, the frequency of the combination of the light-emitting units that glow and the light-emitting units that are extinguished in the flowing light within a unit viewing angle is p4, p4>p3).

[0188] S804: Play the audio anti-sickness content corresponding to the motion information.

[0189] For example, in addition to displaying visual motion sickness prevention content, the vehicle 10 may also play audio motion sickness prevention content to indicate part or all of the motion information. In this way, the motion information perceived by the passenger's vision, vestibule, and auditory senses can be kept consistent, which is beneficial for further alleviating the passenger's motion sickness.

[0190] For example, based on the operating information, the vehicle 10 can select one or more audio playback devices from the audio playback devices of the vehicle 10 (such as audio, speakers, car computers, car tablets, etc.) to play audio anti-sickness content, and indicate changes in motion information through changes in the audio characteristics of the audio anti-sickness content.

[0191] In some embodiments, the audio features of the audio anti-sickness content may include, but are not limited to, frequency, loudness, timbre, sound and image movement speed, rhythm, tempo, etc. In some embodiments, the vehicle 10 may utilize spatial audio stereo to simulate the location of the sound source, i.e., sound and image. The direction of vehicle motion may be indicated by a sound and image moving in the direction opposite to the direction of vehicle motion. Information on vehicle motion intensity (e.g., speed, acceleration, rate of change of acceleration, angular velocity, magnitude of angular acceleration, etc.) may be indicated by the loudness, frequency, timbre, tempo, etc. of the sound. For example, the sound and image position may be located in front of the passenger, and a sound message with a gradually faster tempo may prompt the vehicle to accelerate forward, or a sound message with a gradually slower tempo may prompt the vehicle to decelerate forward.

[0192] In some embodiments, the vehicle 10 may also obtain audio characteristics of the ambient sound in the vehicle 10 and configure the range of audio characteristics of the audio anti-sickness content based on the audio characteristics of the ambient sound. This can prevent ambient sound from causing passengers to be unable to hear the audio anti-sickness content, and can also prevent the intensity of the audio anti-sickness content (such as frequency, loudness, tempo, etc.) from being too strong and affecting passengers.

[0193] For example, if the ambient sound is loud, the vehicle 10 can adjust the loudness of the audio anti-sickness content to a higher loudness range to prevent the target passengers from being unable to hear the audio anti-sickness content due to the loudness of the ambient sound. If the ambient sound is quiet, the vehicle 10 can adjust the loudness of the audio anti-sickness content to a lower loudness range to prevent the excessive loudness of the audio anti-sickness content from causing discomfort to the passengers.

[0194] For another example, if the primary frequencies of ambient sound are concentrated in a first frequency range, the vehicle 10 can control the primary frequencies of the audio motion sickness prevention content to be concentrated in a second frequency range, where the second frequency range partially overlaps with or does not overlap with the first frequency range. This prevents interference between the ambient sound and the audio motion sickness prevention content, which could result in the audio motion sickness prevention content being unable to accurately indicate the vehicle 10's motion information.

[0195] It should be noted that step S804 is optional. That is, in some embodiments, the vehicle 10 may not play the audio anti-sickness content.

[0196] It should be noted that the above steps S801 and S804 can be implemented by a module or device in the vehicle 10, or can be implemented by multiple modules or devices in the vehicle 10, and this is not limited here. For example, the above steps S801 to S804 can be implemented by the vehicle computer CM1. For another example, steps S801, S803, and S804 can be implemented by the vehicle computer CM1, and step S802 can be implemented by other devices in the vehicle 10, such as a controller. For another example, steps S801 and S802 can be implemented by the vehicle computer CM1, and steps S803 and / or S804 can be implemented by the vehicle tablet computer PD1 and / or the vehicle tablet computer PD2 and / or the projector P.

[0197] Based on the above display method, the vehicle 10 can display visual anti-motion sickness content that matches the vehicle motion information, thereby stimulating the passenger's visual perception of motion information that is consistent with the motion information perceived by the vestibule, which is helpful in alleviating the passenger's motion sickness.

[0198] An embodiment of the present application provides a vehicle 10 , and one or more modules in the vehicle 10 can be used to implement the display method provided in the embodiment of the present application.

[0199] Exemplarily, FIG11 shows a schematic structural diagram of a vehicle 10 according to some embodiments of the present application.

[0200] As shown in FIG11 , the vehicle 10 may include various subsystems, such as a travel system 102, a sensor system 104, a control system 106, one or more peripheral devices 108, a power source 110, a computer system 112, and a user interface 116. Alternatively, the vehicle 10 may include more or fewer subsystems, and each subsystem may include multiple components. In addition, each subsystem and component of the vehicle 10 may be interconnected via wired or wireless connections.

[0201] The propulsion system 102 may include components that provide powered motion for the vehicle 10.
