[0050] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0051] A starry sky headliner is a vehicle headliner with multiple light spots on its surface and several optical fibers integrated on its back. Each fiber serves as a light spot on the headliner, simulating starlight. As a feature in high-end vehicles, starry sky headliners often create a romantic atmosphere for passengers inside the car through the changing shimmering of multiple light spots.

[0052] In related technologies, starry sky headliners are often used as ambient lighting, serving to decorate and beautify the vehicle interior. However, they do not significantly improve practical aspects such as passenger safety and ride comfort. This makes the decorative value of starry sky headliners excessive, while their practical value is lacking. Therefore, how to improve the practical value of starry sky headliners is an urgent problem to be solved.

[0053] Meanwhile, due to the limitations of the vehicle's structure, passengers in the rear seats cannot perceive changes in the vehicle's tilt angle caused by changes in road conditions while the vehicle is in motion. This can easily cause passengers to be startled or even injured when the vehicle's vibrations increase.

[0054] Based on this, this application proposes a starry sky canopy control method, system, storage medium, and vehicle. The method uses different lighting patterns of the starry sky canopy to represent different levels of vehicle bumps, allowing rear-seat passengers to perceive changes in road conditions and vehicle tilt angle in real time. This helps prevent passengers from being startled during bumpy rides, improving driving safety and passenger comfort, and giving the starry sky canopy practical value. Specifically, it includes:

[0055] The first aspect of this application provides an embodiment, such as... Figure 1 The diagram illustrates a method for controlling a starry sky ceiling. This embodiment includes a method for controlling a starry sky ceiling, which is applied to an on-board controller and specifically includes:

[0056] Step S101: During the vehicle's operation, acquire the vehicle's bump information, which includes the vehicle's tilt direction, tilt speed, and tilt amplitude.

[0057] Bump information is used to characterize the degree of vehicle body bumps during driving and is a type of information determined based on the vehicle's posture. Bump information includes the direction of vehicle tilt, the speed of vehicle tilt, and the magnitude of vehicle tilt.

[0058] In one optional implementation, bump information can be acquired using a gyroscope installed on the vehicle. The changes in various parameters of the vehicle's tilt angle are determined by the real-time detection of the vehicle's tilt angle by the gyroscope. The direction in which the vehicle tilt angle points is the vehicle's tilt direction, the rate of change of the tilt angle is the vehicle's tilt rate, and the magnitude of the tilt angle is the vehicle's tilt amplitude. Alternatively, the vehicle tilt angle can also be acquired using multiple height sensors respectively arranged on the front and rear axles; this application does not limit this method.

[0059] In layman's terms, the direction of vehicle tilt can be intuitively determined by the relative height of the front and rear of the vehicle, as well as the relative height of the left and right sides of the vehicle. For example, when the front of the vehicle is higher than the rear, the vehicle is tilting backward; conversely, it is tilting forward. When the left side of the vehicle is higher than the right side, the vehicle is tilting to the right; conversely, it is tilting to the left.

[0060] The degree of vehicle tilt can be intuitively judged by the relative height difference between the front and rear of the vehicle, and the relative height difference between the left and right sides of the vehicle. Taking the case where the vehicle tilts backward as an example, when the vehicle tilts backward, the front of the vehicle is higher than the rear. In this case, the higher the front of the vehicle is relative to the rear, the greater the degree of vehicle tilt.

[0061] The vehicle's tilt rate can be intuitively judged by the rate of change of the relative height difference between the front and rear of the vehicle, and the rate of change of the relative height difference between the left and right sides of the vehicle. Taking the case where the vehicle is tilting backward as an example, when the vehicle is tilting backward, the front of the vehicle is higher than the rear. In this case, the faster the front of the vehicle rises or the faster the rear of the vehicle falls, the faster the rate of change of the relative height difference between the front and rear of the vehicle, further indicating a faster tilt rate.

[0062] Step S102: Based on the vehicle body tilt amplitude and the vehicle body tilt direction, determine the target range of the multiple light-emitting units to be lit in the starry sky ceiling, and based on the vehicle body tilt speed, determine the lighting time interval between each light-emitting unit within the target range.

[0063] The degree of vehicle tilt, the direction of vehicle tilt, and the speed of vehicle tilt are important parameters that affect the degree of vehicle bumps during driving. Therefore, when it is difficult for users to intuitively feel or judge the degree of vehicle bumps, if the lighting method of the starry sky canopy is determined by the degree of vehicle tilt, the direction of vehicle tilt, and the speed of vehicle tilt, users can accurately judge the degree of vehicle bumps by observing the changes in the starry sky canopy.

[0064] The starry sky ceiling consists of multiple light-emitting units, each containing one or more light spots. The lighting and extinguishing of each light-emitting unit can be controlled individually.

[0065] The target range of the multiple light-emitting units to be lit is determined by the vehicle body tilt amplitude and tilt direction. The size of the target range is determined by the vehicle body tilt amplitude, and the position of the target range is determined by the vehicle body tilt direction.

[0066] Specifically, the size of the target area increases with the increase of the vehicle's tilt angle. In actual calculations, the size of the target area can be calculated by combining a pre-determined ratio parameter between the target area size and the vehicle tilt angle, as well as the obtained vehicle tilt angle. The location of the target area is determined by the vehicle's tilt direction; the target area is located where the vehicle's tilt direction points. For example, when the vehicle tilts forward, the target area is located in front of the starry sky roof.

[0067] The lighting time interval between each light-emitting unit within the target area is determined by the vehicle's tilt speed. The faster the vehicle tilts, the shorter the lighting time interval between each light-emitting unit, and the shorter the time required to light up all the light-emitting units within the target area. In actual calculations, the lighting time interval can be calculated by combining a pre-determined ratio parameter between the lighting time interval and the vehicle tilt speed, as well as the obtained vehicle tilt speed.

[0068] Step S103: Based on the lighting time interval, control multiple light-emitting units within the target range to light up sequentially, so that the lighting sequence of each light-emitting unit points to the vehicle body tilt direction.

[0069] After determining the target range of multiple light-emitting units to be lit based on the acquired vehicle tilt direction, vehicle tilt speed, and vehicle tilt amplitude, and the lighting time interval between the lighting times of each light-emitting unit, the multiple light-emitting units within the target range are controlled to be lit sequentially, so that the lighting order of each light-emitting unit points to the vehicle tilt direction, that is, the multiple light-emitting units are controlled to be lit sequentially in the order pointed to by the vehicle tilt direction.

[0070] For example, when the vehicle body is tilted forward, the target area can be determined to be located in front of the starry sky roof. The front of the starry sky roof can be the portion near the front of the vehicle, with the center line of the starry sky roof as the dividing line. Furthermore, by combining this with the degree of vehicle tilt, the size of the target area can be determined. The greater the degree of vehicle tilt, the larger the proportion of the target area to the starry sky roof area, and the greater the distance between the illuminated light unit and the center line of the starry sky roof.

[0071] Based on this, by controlling multiple light-emitting units within the target area to illuminate sequentially in the order pointed to by the vehicle's tilt direction, with the illumination time interval being the interval between the illumination of each unit, the starry sky headliner will give occupants the visual perception that the illuminated area on the headliner is moving at a certain speed in the direction pointed to by the vehicle's tilt direction. Furthermore, the greater the vehicle's tilt angle, the greater the displacement of the illuminated area; the greater the vehicle's tilt speed, the greater the speed of the illuminated area. Therefore, occupants can intuitively perceive the vehicle's tilt direction from the direction of the illuminated area's movement, the vehicle's tilt speed from the speed of the illuminated area's movement, and the vehicle's tilt angle from the displacement of the illuminated area. This allows occupants to perceive road conditions and changes in vehicle tilt angle based on the changes in the starry sky headliner's illumination pattern, thus preventing occupants from being startled during vehicle bumps, improving driving safety and ride comfort, and giving the starry sky headliner practical value.

[0072] The second aspect of this application provides an embodiment that, in addition to including the embodiment proposed in the first aspect of this application, also includes:

[0073] Optionally, such as Figure 2 The diagram illustrates a method for determining the first luminous intensity of a light-emitting unit, the method comprising:

[0074] Step S201: Obtain the light intensity inside the vehicle's driver's cab.

[0075] To ensure that occupants can clearly perceive the difference between the illuminated and de-illuminated states of each light-emitting unit on the starry sky ceiling, the brightness of the illuminated unit when illuminated should be significantly greater than the ambient light level of the occupants' environment. Based on this, the illumination brightness of the light-emitting unit can be determined using the ambient light level described by the occupants; that is, the illumination brightness of the light-emitting unit can be determined based on the ambient light level inside the vehicle's driver's compartment.

[0076] In one alternative implementation, the light intensity inside the driver's cab can be collected by a brightness sensor. Preferably, to improve the accuracy of the illumination brightness of the light-emitting unit, the brightness sensor can be installed near the starry sky ceiling.

[0077] Step S202: Determine the first luminous brightness of the light-emitting unit based on the light brightness.

[0078] After obtaining the light intensity inside the driver's cab, the first luminous intensity can be determined by a predetermined calculation formula. The calculation formula for determining the first luminous intensity based on the light intensity inside the driver's cab can be determined based on relevant technologies or common knowledge in the field, and will not be elaborated here.

[0079] Step S203: Based on the lighting time interval, control multiple light-emitting units within the target range to be lit sequentially according to the first luminous brightness.

[0080] After determining the first luminous brightness of the light-emitting unit, based on step S103, during the process of sequentially lighting up the light-emitting units within the target range, multiple light-emitting units are controlled to be lit up at the first luminous brightness.

[0081] Optionally, such as Figure 3 The diagram illustrates a method for lighting a light-emitting unit. Step S103 further includes:

[0082] Step S1031: Based on the vehicle body tilt direction and the lighting time interval, determine the lighting time of each light-emitting unit within the target range.

[0083] Taking the lighting time of the reference light-emitting unit that is furthest from the direction pointed to by the vehicle body tilt direction within the target range as the zero point, the lighting times of multiple light-emitting units within the target range can be determined sequentially based on the vehicle body tilt direction and the time interval of the power supply.

[0084] For example, when the vehicle body is tilted forward, the target area can be determined to be located in front of the starry sky roof, where the center line of the starry sky roof is the dividing line, and the area closest to the front of the vehicle is the part of the target area. At this time, the reference light-emitting unit that is farthest from the direction pointed to by the vehicle body tilt is the light-emitting unit closest to the center line of the starry sky roof within the target area, and the lighting time of the reference light-emitting unit is taken as the zero point.

[0085] After determining the zero point, the lighting time of the next light-emitting unit adjacent to the reference light-emitting unit in the vehicle body tilt direction is the zero point plus one unit of lighting time interval. Similarly, the lighting times of the remaining light-emitting units can be obtained.

[0086] Step S1032: Control the light-emitting unit to be lit at the corresponding lighting moment.

[0087] After determining the lighting time of each light-emitting unit, control each light-emitting unit to be lit at its corresponding lighting time.

[0088] Optionally, in step S102, determining the target range of the multiple light-emitting units to be lit in the starry sky ceiling based on the vehicle body tilt amplitude and the vehicle body tilt direction further includes:

[0089] In scenario one, if the vehicle body tilt angle is less than a preset angle, the target range is determined to be the first area of ​​the starry sky ceiling, wherein the first area is the central area.

[0090] When the vehicle body tilt is less than a preset value, the vehicle can be considered to be in a stable state. At this time, the degree of body sway has no significant impact on the safety and comfort of the occupants. Therefore, the target range can be defined as the first area located in the center of the starry sky ceiling, so that the illuminated light-emitting unit is located in the center of the starry sky ceiling without any tendency to deviate, thereby allowing the user to perceive that the vehicle is in a stable state through the light-emitting unit located in the center area.

[0091] Scenario 2: If the vehicle body tilt angle is greater than or equal to the preset angle, the target range is determined to be the second region on the starry sky roof that corresponds to the vehicle body tilt direction; wherein, the second region is the region that is off from the central region.

[0092] When the vehicle body tilts at an angle greater than or equal to a preset angle, the vehicle is considered to be in a bumpy state. At this time, the degree of bumpiness has a significant impact on the safety and comfort of the occupants. Therefore, the target area can be defined as a second area away from the center of the starry sky ceiling, so that the illuminated light-emitting units have a certain offset tendency relative to the center area of ​​the starry sky ceiling, thereby allowing users to perceive that the vehicle is in a bumpy state through the light-emitting units that are off-center from the center area.

[0093] Optionally, such as Figure 4 The diagram illustrates a method for determining the illuminated color of a light-emitting unit, the method comprising:

[0094] Step S301: Based on the vehicle body tilt speed and / or the vehicle body tilt amplitude, determine the illumination color of the multiple light-emitting units within the target range.

[0095] In addition to conveying vehicle bump information through the lighting interval of the light-emitting units, the target range of the light-emitting units to be lit, and the order in which multiple light-emitting units are lit, the starry sky canopy can also convey information through the lighting color of the light-emitting units. The lighting color of the light-emitting units is determined by the vehicle tilt speed or the vehicle tilt amplitude, or by both the vehicle tilt speed and the vehicle tilt amplitude.

[0096] In one optional implementation, if the vehicle body tilt angle exceeds a first preset angle, or the vehicle body tilt speed exceeds a first preset speed, it indicates that the vehicle is currently experiencing significant bumps, which greatly affects the passenger's comfort and may even threaten their safety. In this situation, the vehicle is in a dangerous condition, and the illumination color of the light-emitting unit should be set to red to warn the user.

[0097] If the vehicle tilt angle is less than or equal to a first preset angle and the vehicle tilt speed is less than or equal to a first preset angle, but the vehicle tilt angle is greater than a second preset angle or the vehicle tilt speed is greater than a second preset speed, it indicates that the current level of vehicle bumps has a certain impact on passenger comfort, but poses no significant threat to passenger safety. In this case, the illumination color of the light-emitting unit can be set to yellow. If the vehicle tilt angle is less than or equal to a second preset angle and the vehicle tilt speed is less than or equal to a second preset speed, it indicates that the current level of vehicle bumps has neither an impact on passenger comfort nor a significant threat to passenger safety. In this case, the illumination color of the light-emitting unit can be set to green. The second preset angle is less than the first preset angle, and the second preset speed is less than the first preset speed.

[0098] In addition, if the vehicle tilts more than a preset angle or the vehicle tilts at a speed greater than a preset speed, the system can also remind occupants to wear seat belts or slow down via voice or image information.

[0099] Step S302: Based on the lighting time interval, control multiple light-emitting units within the target range to be lit sequentially according to the lighting color.

[0100] Once the illumination color of the light-emitting unit is determined, based on step S103, during the process of sequentially illuminating the light-emitting units within the target range, multiple light-emitting units are controlled to be illuminated with their corresponding illumination colors.

[0101] Optionally, such as Figure 5 The diagram illustrates a method for determining the second luminous intensity of a light-emitting unit, the method comprising:

[0102] Step S401: Determine the second luminous brightness of each of the light-emitting units based on the distance between the light-emitting units within the target range and the center point of the starry sky ceiling.

[0103] To enrich the visual experience of the occupants, the second luminous brightness of the luminous unit can also be determined by the distance between the luminous unit and the center point of the starry sky ceiling, so that the brightness of multiple luminous units varies during the lighting process, giving the occupants a more varied visual experience.

[0104] Step S402: Based on the lighting time interval, control multiple light-emitting units within the target range to be lit sequentially according to the second luminous brightness.

[0105] After determining the second luminous brightness of the light-emitting unit, based on step S103, during the process of sequentially lighting up the light-emitting units within the target range, multiple light-emitting units are controlled to be lit up with their corresponding second luminous brightness.

[0106] Optionally, such as Figure 6 The diagram illustrates a method for determining a second luminous intensity, the method comprising:

[0107] Step S4011: Determine the central luminous brightness of the central luminous unit located at the midpoint of the starry sky ceiling.

[0108] Before determining the second luminous brightness of each luminous unit, the second luminous brightness should first be determined based on the distance change from the midpoint of the starry sky ceiling. That is, the center luminous brightness of the luminous unit located at the end of the starry sky ceiling should be determined, and then the second luminous brightness of each luminous unit should be determined based on this benchmark.

[0109] In one alternative implementation, the central luminous brightness of the central luminous unit can be determined by the ambient light level inside the driver's cab. The greater the ambient light level inside the driver's cab, the greater the central luminous brightness should be to facilitate the occupants' perception of changes in the starry sky ceiling.

[0110] Step S4012: Determine the brightness attenuation coefficient of each light-emitting unit relative to the central light-emitting unit based on the distance between the light-emitting units within the target range and the central light-emitting unit.

[0111] The brightness attenuation coefficient refers to the ratio between the second luminance of the light-emitting unit and the central luminance. It varies with the distance between the light-emitting unit and the central luminance. It can increase with the increase of the distance between the light-emitting unit and the central luminance, or decrease with the increase of the distance between the light-emitting unit and the central luminance, or have other relationships with the distance between the light-emitting unit and the central luminance.

[0112] Step S4013: Determine the second luminous brightness of each luminous unit within the target range based on the luminous attenuation coefficient and the central luminous brightness.

[0113] After determining the brightness attenuation coefficient, the second luminous brightness of each luminous unit can be determined by multiplying the brightness attenuation coefficients corresponding to the luminous units.

[0114] A third aspect of this application provides an embodiment, such as... Figure 7 A flowchart illustrating a method for controlling a starry sky ceiling is shown, the method comprising:

[0115] First, acquire the parameters required to control each light-emitting unit on the starry sky ceiling, including: the light brightness in the vehicle's cab, the vehicle's bump information, and the central light-emitting brightness of the central light-emitting unit and the brightness attenuation coefficient of each light-emitting unit relative to the central light-emitting unit. The bump information includes: the vehicle's tilt direction, the vehicle's tilt speed, and the vehicle's tilt amplitude.

[0116] Subsequently, based on the acquired parameters, the parameters required to light up each light-emitting unit are determined so that the vehicle's bumps can be reflected by the light-emitting units on the starry sky canopy. The parameters required to light up each light-emitting unit include: the first luminous brightness of the light-emitting unit, the lighting time interval between each light-emitting unit, the target range of the light-emitting unit to be lit, the lighting color of the light-emitting unit when it is lit, and the second luminous brightness of each light-emitting unit.

[0117] Specifically, the steps for determining the first luminous brightness of the light-emitting unit include: acquiring the light brightness inside the vehicle's driver's cab; and determining the first luminous brightness of the light-emitting unit based on the light brightness.

[0118] The steps for determining the lighting time interval between each light-emitting unit include: determining the lighting time interval between each light-emitting unit within the target range based on the vehicle body tilt speed.

[0119] The steps for determining the target range of the light-emitting units to be illuminated include: determining the target range of multiple light-emitting units to be illuminated in the starry sky ceiling based on the vehicle body tilt amplitude and tilt direction. Specifically, if the vehicle body tilt amplitude is less than a preset amplitude, the target range is determined as a first area of ​​the starry sky ceiling; if the vehicle body tilt amplitude is greater than or equal to the preset amplitude, the target range is determined as a second area on the starry sky ceiling corresponding to the vehicle body tilt direction; wherein the first area is the central area, and the second area is an area off-center from the central area.

[0120] The steps for determining the illumination color of the light-emitting unit when it is lit include: determining the illumination color of multiple light-emitting units within the target range based on the vehicle body tilt speed and / or vehicle body tilt amplitude.

[0122] Finally, after determining the parameters required to illuminate each light-emitting unit, the system controls each light-emitting unit to illuminate according to its corresponding parameters. Specifically, the system uses the illumination time interval as the interval between the times when each light-emitting unit is illuminated, the first luminous brightness or the second luminous brightness as the luminous brightness of the light-emitting unit, and the illumination color as the color of the light when the light-emitting unit is illuminated. The system controls multiple light-emitting units within the target range to illuminate sequentially in the order indicated by the vehicle's tilt direction.

[0123] In the case of controlling multiple light-emitting units within the target range to light up sequentially according to the order pointed to by the vehicle body tilt direction, the lighting time of each light-emitting unit within the target range can be determined based on the vehicle body tilt direction and the lighting time interval, and the method of controlling the light-emitting units to be lit up at the corresponding lighting time can be implemented.
