Description

Technical Field

[0001] This invention relates to the field of vehicle technology, and in particular to a method, system, device and medium for controlling vehicle ambient lighting. Background Technology

[0002] In existing vehicle cabins, ambient lighting parameters are either fixed or manually adjustable by the user. These parameters cannot dynamically adjust based on the driver's driving scenario and ambient light conditions. For example, during the day or in bright sunlight, if the ambient lighting maintains a fixed brightness, its effect can be weakened by ambient light interference, making it difficult for the user to perceive. Conversely, at night or in low light, if the ambient lighting brightness is not adjusted in time, the glare can be blinding, compromising driving comfort. These driving scenarios may present safety hazards due to untimely ambient lighting adjustments, thus requiring improvement. Summary of the Invention

[0003] This invention provides a method, system, device, and medium for controlling vehicle ambient lighting, in order to solve the technical problem of safety hazards caused by the failure to adjust ambient lighting in a timely manner in the prior art.

[0004] This invention provides a method for controlling vehicle ambient lighting, comprising:

[0005] Continuously collect ambient light intensity during vehicle operation;

[0006] Based on multiple preset light intensity ranges, determine the light intensity range corresponding to the ambient light intensity at the previous moment, and the light intensity range corresponding to the current ambient light intensity.

[0007] Compare the previous light intensity range with the current light intensity range:

[0008] If the current light intensity range differs from the current light intensity range, switch the ambient light's lighting mode; otherwise, maintain the ambient light's lighting mode.

[0009] In one embodiment of the present invention, when the current light intensity range differs from the current light intensity range, the step of switching the ambient light's illumination mode includes:

[0010] When the current light intensity range is different from the current light intensity range, the target lighting mode corresponding to the current light intensity range is obtained based on the preset mode mapping relationship, and the ambient light is controlled to switch to the target lighting mode; where the mode mapping relationship represents the mapping relationship between the light intensity range and the ambient light lighting mode.

[0011] In one embodiment of the present invention, the step of controlling the ambient light to switch to the target lighting mode includes:

[0012] Determine the light intensity range from the previous moment to the current light intensity range:

[0013] When the light intensity range of the previous moment is adjacent to the current light intensity range, the ambient light is controlled to switch directly from the lighting mode corresponding to the light intensity range of the previous moment to the target lighting mode corresponding to the current light intensity range.

[0014] When the light intensity range of the previous moment and the current light intensity range are not adjacent light intensity ranges, the ambient light is controlled to linearly switch from the lighting mode corresponding to the light intensity range of the previous moment, through the lighting mode corresponding to the light intensity range between the previous moment and the current light intensity range, to the target lighting mode corresponding to the current light intensity range.

[0015] In one embodiment of the present invention, when the current light intensity range differs from the current light intensity range, the step of switching the ambient light's illumination mode includes:

[0016] When the lower limit of the light intensity of the current light intensity range is greater than the maximum value of the preset light intensity range, and the light intensity of the current light intensity range is within the preset light intensity range, the lighting mode of the ambient light is switched, so that the brightness of the ambient light is reduced from the first brightness range to the second brightness range.

[0017] Alternatively, if the light intensity of the current light intensity range is within the preset light intensity range, and the upper limit of the light intensity of the current light intensity range is less than the minimum value of the preset light intensity range, the lighting mode of the ambient light is switched, so that the brightness of the ambient light is reduced from the second brightness range to the third brightness range.

[0018] In one embodiment of the present invention, when the current light intensity range differs from the current light intensity range, the step of switching the ambient light's illumination mode includes:

[0019] When the lower limit of the light intensity of the current light intensity range is greater than the maximum value of the preset light intensity range, and the light intensity of the current light intensity range is within the preset light intensity range, the lighting mode of the ambient light is switched so that the color temperature of the ambient light is reduced from the first color temperature range to the second color temperature range.

[0020] Alternatively, if the light intensity of the current light intensity range is within the preset light intensity range, and the upper limit of the light intensity of the current light intensity range is less than the minimum value of the preset light intensity range, the lighting mode of the ambient light is switched, so that the color temperature of the ambient light is reduced from the second color temperature range to the third color temperature range.

[0022] Get the status of the speakers used by the ambient lighting:

[0023] When the speaker is not in operation and the lower limit of the current light intensity range is greater than the maximum value of the preset light intensity range, turn off the ambient light.

[0024] Otherwise, compare the light intensity range from the previous moment with the current light intensity range.

[0025] In one embodiment of the present invention, the step of comparing the light intensity range of the previous moment with the current light intensity range includes:

[0026] Obtain the driver's line of sight:

[0027] When the line of sight is directed toward the rearview mirror, and the upper limit of the current light intensity range is less than the minimum value of the preset light intensity range, the brightness of the ambient light in the current lighting mode is reduced.

[0028] Otherwise, compare the light intensity range from the previous moment with the current light intensity range.

[0029] The present invention also proposes a control system for vehicle ambient lighting, comprising:

[0030] The data acquisition unit is used to continuously collect ambient light intensity during vehicle operation.

[0031] The light intensity determination unit is used to determine the light intensity interval corresponding to the ambient light intensity at the previous moment and the light intensity interval corresponding to the current ambient light intensity based on multiple preset light intensity intervals.

[0032] The comparison unit is used to compare the light intensity range of the previous moment with the current light intensity range:

[0033] The control unit is used to switch the ambient light's lighting mode when the current light intensity range differs from the current light intensity range; otherwise, it maintains the ambient light's lighting mode.

[0034] The present invention also proposes an electronic device, the electronic device comprising:

[0035] One or more processors;

[0036] A storage device for storing one or more programs, which, when executed by the one or more processors, cause the electronic device to implement the vehicle ambient lighting control method as described above.

[0037] The present invention also proposes a computer-readable storage medium having a computer program stored thereon, which, when executed by a computer processor, causes the computer to perform any of the above-described vehicle ambient lighting control methods.

[0038] The beneficial effects of this invention are as follows: The method, system, device, and medium for controlling vehicle ambient lighting proposed in this invention continuously collects the ambient light intensity during vehicle operation to determine the previous ambient light intensity range and the current ambient light intensity range. The previous and current ambient light intensity ranges are compared, and when they differ, the ambient light lighting mode is switched. This ensures timely adjustment of the ambient light, avoids safety hazards, and guarantees the visibility and comfort of the lighting effects under different ambient lighting conditions.

In other embodiments, well-known structures and devices are shown in block diagram form rather than in detail to avoid obscuring embodiments of the invention.

[0047] Please see Figures 1 to 3 This invention proposes a method, system, device, and medium for controlling vehicle ambient lighting, applicable to the automotive field. It enables speaker ambient lighting control based on environmental perception, ensuring visibility and comfort of lighting effects under different ambient lighting conditions while optimizing energy consumption. Detailed descriptions are provided below using specific embodiments.

[0048] Please see Figure 1 , Figure 1 A method for controlling vehicle ambient lighting according to an embodiment of the present invention may include the following steps.

[0049] Step S10: Continuously collect ambient light intensity during vehicle operation.

[0050] Specifically, an ambient light sensor installed inside the vehicle continuously collects data on the ambient light intensity experienced by the vehicle during operation. The ambient light sensor samples once per second, ensuring that it can capture the continuous changes in ambient light intensity from 0 lux to 2000 lux in real time, providing an accurate data foundation for subsequent intelligent decision-making.

[0051] Step S20: Based on multiple preset light intensity ranges, determine the light intensity range corresponding to the ambient light intensity at the previous moment and the light intensity range corresponding to the current ambient light intensity.

[0052] Specifically, after acquiring real-time ambient light intensity data, the data is categorized according to several preset light intensity ranges. These preset ranges are clearly defined as follows: ambient light intensity less than or equal to 50 lux is defined as a weak light range; ambient light intensity greater than 50 lux and less than 500 lux is defined as a transitional light range; and ambient light intensity greater than or equal to 500 lux is defined as a strong light range. The system also determines which light intensity range the ambient light intensity collected at the previous sampling time belongs to, i.e., the previous time's light intensity range, and simultaneously determines which light intensity range the ambient light intensity collected at the latest sampling time belongs to, i.e., the current light intensity range.

[0053] Step S30: Compare the light intensity range of the previous moment with the current light intensity range.

[0054] Specifically, the determined light intensity range of the previous moment is logically compared with the current light intensity range. The purpose of the comparison is to determine whether the lighting environment in which the vehicle is located has undergone a qualitative change, that is, whether it has changed from one light level to another.

[0055] Step S40: If the light intensity range at the previous moment is different from the current light intensity range, switch the ambient light's lighting mode; otherwise, keep the ambient light's lighting mode.

[0056] Specifically, if the comparison shows that the light intensity range of the previous moment is different from the current light intensity range, it indicates that the ambient lighting conditions have crossed the preset threshold and have changed significantly. At this time, the system will trigger the switching action of the ambient lighting mode.

[0057] For example, if a vehicle exits a tunnel (low-light zone) and enters daytime outdoor lighting (high-light zone), the system will switch the ambient lighting from a low-brightness warm-colored lighting mode suitable for low-light zones to a high-brightness cool-colored lighting mode suitable for high-light zones, to ensure that the lighting effect maintains optimal visibility and comfort under different ambient light conditions.

[0058] Conversely, if the comparison shows that the light intensity range of the previous moment is the same as the current light intensity range, it means that although there may be slight fluctuations in the ambient light intensity, it is still within the same light level range overall. In this case, the system will maintain the current lighting mode of the ambient light to avoid unnecessary frequent switching, thereby ensuring the stability of the light output and the consistency of the user experience.

[0059] For example, if a vehicle is driving at a constant speed during the day and the ambient light intensity fluctuates between 550 lux and 600 lux, but is always within the strong light range, then the ambient lights will maintain their high-brightness, cool-colored lighting mode.

[0060] In one embodiment of the present invention, step S40, when the light intensity range at a previous moment is different from the current light intensity range, the step of switching the lighting mode of the ambient light may include the following steps.

[0061] When the current light intensity range is different from the current light intensity range, the target lighting mode corresponding to the current light intensity range is obtained based on the preset mode mapping relationship, and the ambient light is controlled to switch to the target lighting mode; where the mode mapping relationship represents the mapping relationship between the light intensity range and the ambient light lighting mode.

[0062] Specifically, it can access its internally pre-stored pattern mapping relationship, which clearly defines the unique ambient lighting mode corresponding to each light intensity range. It is a core logical rule that binds ambient lighting conditions with specific light output parameters.

[0063] Based on the determined current light intensity range, the above-mentioned pattern mapping relationship is queried to obtain the target lighting pattern that precisely matches that range. For example, if the current light intensity range is determined to be a low-light range, i.e., the ambient light intensity is less than or equal to 50 lux, then by querying the pattern mapping relationship, the target lighting pattern obtained is a combination of lighting parameters with a brightness range of 10% to 30%, using low-saturation warm colors (such as beige or light orange), and a color temperature range of 2700K (Kelvin) to 3500K.

[0064] For example, if the current light intensity range is determined to be a transitional light range (ambient light intensity greater than 50 lux and less than 500 lux), then the resulting target lighting mode is a combination of lighting parameters where brightness changes linearly with light intensity, using medium-saturation neutral colors, and a color temperature range between 3500K and 5000K. If the current light intensity range is determined to be a strong light range (ambient light intensity greater than or equal to 500 lux), then the resulting target lighting mode is a combination of lighting parameters where brightness ranges between 70% and 100%, using high-saturation cool colors, and a color temperature range between 5000K and 6500K.

[0065] After successfully acquiring the specific parameters of the target lighting mode, a control command is sent to the ambient light's execution module, driving the ambient light to switch from the original lighting mode to this newly determined target lighting mode. Specifically, the control unit outputs a corresponding pulse width modulation signal to adjust the current of the LED light group, causing the brightness, color, and color temperature of the ambient light to gradually change to the values ​​specified by the target lighting mode. For example, switching from a high-brightness cool-color mode in the strong light range to a low-brightness warm-color mode in the weak light range is a concrete manifestation of finding the target and executing the switch according to the mapping relationship.

[0066] In one embodiment of the present invention, step S40, which controls the ambient light to switch to the target lighting mode, may include the following steps.

[0067] Step S410: Determine the light intensity range of the previous moment and the current light intensity range.

[0068] Step S420: When the light intensity range of the previous moment and the current light intensity range are adjacent light intensity ranges, control the ambient light to switch directly from the lighting mode corresponding to the light intensity range of the previous moment to the target lighting mode corresponding to the current light intensity range.

[0069] Specifically, if the determination result indicates that the previous light intensity range and the current light intensity range are adjacent light intensity ranges, the system will control the ambient light to perform a direct switching method. In other words, the ambient light will immediately switch from its current lighting mode, which is determined by the previous light intensity range, to the target lighting mode corresponding to the current light intensity range.

[0070] For example, when a vehicle enters a tunnel from a cloudy environment, and the lighting conditions quickly change from the transition light range to the low light range, since these two ranges are adjacent, the system will control the ambient lighting to immediately change from the medium brightness, neutral color temperature and color mode corresponding to the transition light to the low brightness, warm color temperature and low saturation color mode corresponding to the low light.

[0071] Step S430: When the light intensity range of the previous moment and the current light intensity range are not adjacent light intensity ranges, control the ambient light to linearly switch from the lighting mode corresponding to the light intensity range of the previous moment, through the lighting mode corresponding to the light intensity range between the previous moment and the current light intensity range, to the target lighting mode corresponding to the current light intensity range.

[0072] Conversely, if the judgment result indicates that the light intensity range of the previous moment and the current light intensity range are not adjacent, specifically referring to a situation where there is a direct transition from a low-light range to a high-light range, or vice versa, the system will control the ambient light to perform a linear switching method with an intermediate transition.

[0073] Specifically, the ambient light will change from its current lighting mode, which is determined by the light intensity range of the previous moment. First, it will pass through the lighting mode corresponding to the intermediate light intensity range between the two non-adjacent ranges, and then smoothly and linearly transition to the target lighting mode finally determined by the current light intensity range.

[0074] For example, when a vehicle emerges from a tunnel at night and is suddenly exposed to midday sunlight, the lighting conditions change abruptly from a low-light to a high-light range, skipping the intermediate transitional light zone. The system does not allow the ambient lighting to jump directly from low-brightness, warm colors to high-brightness, cool colors. Instead, it first controls the lighting parameters to shift towards a medium-brightness, neutral-color-temperature mode corresponding to the transitional light zone. Using this as a bridge, it then linearly transitions to the high-brightness, cool-color mode corresponding to the high-light range. This creates a smooth, gradual visual effect throughout the transition, avoiding the abruptness that might result from drastic changes in lighting parameters.

[0075] In one embodiment of the present invention, step S40, when the light intensity range at a previous moment is different from the current light intensity range, the step of switching the lighting mode of the ambient light may include the following steps.

[0076] When the lower limit of the light intensity of the current light intensity range is greater than the maximum value of the preset light intensity range, and the light intensity of the current light intensity range is within the preset light intensity range, the lighting mode of the ambient light is switched, so that the brightness of the ambient light is reduced from the first brightness range to the second brightness range.

[0077] For example, if the lower limit of the light intensity of the current light intensity range is greater than the maximum value of the preset light intensity range of 500 lux, and the light intensity of the current light intensity range is within the preset light intensity range of 50 lux to 500 lux, the lighting mode of the ambient light is switched so that the brightness of the ambient light is reduced from 70% to 100% in the first brightness range to 30% to 70% in the second brightness range.

[0078] Alternatively, if the light intensity of the current light intensity range is within the preset light intensity range, and the upper limit of the light intensity of the current light intensity range is less than the minimum value of the preset light intensity range, the lighting mode of the ambient light is switched, so that the brightness of the ambient light is reduced from the second brightness range to the third brightness range.

[0079] For example, if the light intensity of the current light intensity range is within the preset light intensity range of 50 lux to 500 lux, and the upper limit of the light intensity of the current light intensity range is less than the minimum value of the preset light intensity range of 50 lux, the lighting mode of the ambient light is switched, so that the brightness of the ambient light is reduced from the second brightness range of 30% to 70% to the third brightness range of 10% to 30%.

[0080] In one embodiment of the present invention, step S40, when the light intensity range at a previous moment is different from the current light intensity range, the step of switching the lighting mode of the ambient light includes:

[0081] When the lower limit of the light intensity of the current light intensity range is greater than the maximum value of the preset light intensity range, and the light intensity of the current light intensity range is within the preset light intensity range, the lighting mode of the ambient light is switched, so that the color temperature of the ambient light is reduced from the first color temperature range to the second color temperature range.

[0082] For example, if the lower limit of the light intensity of the current light intensity range is greater than the maximum value of the preset light intensity range (500 lux), and the light intensity of the current light intensity range is within the preset light intensity range of 50 lux to 500 lux, the lighting mode of the ambient light is switched so that the color temperature of the ambient light is reduced from the first color temperature range of 5000K to 6000K to the second color temperature range of 3500K to 6500K.

[0083] Alternatively, if the light intensity of the current light intensity range is within the preset light intensity range, and the upper limit of the light intensity of the current light intensity range is less than the minimum value of the preset light intensity range, the lighting mode of the ambient light is switched, so that the color temperature of the ambient light is reduced from the second color temperature range to the third color temperature range.

[0084] For example, if the light intensity of the current light intensity range is within the preset light intensity range of 50 lux to 500 lux, and the upper limit of the light intensity of the current light intensity range is less than the minimum value of the preset light intensity range of 50 lux, the lighting mode of the ambient light is switched, so that the color temperature of the ambient light is reduced from the second color temperature range of 3500K to 6500K to the third color temperature range of 2700K to 3500K.

[0085] In one embodiment of the present invention, the step of comparing the light intensity range of the previous moment with the current light intensity range in step S30 may further include the following steps.

[0086] Get the status of the speakers used by the ambient lighting.

[0087] When the speaker is not in operation and the lower limit of the current light intensity range is greater than the maximum value of the preset light intensity range, the ambient light is turned off.

[0088] Otherwise, compare the light intensity range from the previous moment with the current light intensity range.

[0089] Specifically, during the control of the vehicle's ambient lighting, the operating status of the speakers and the ambient light intensity are detected first. When it is confirmed that the speakers are not in operation (i.e., the audio output voltage is below 50 millivolts) and the current ambient light intensity is greater than or equal to 1000 lux, the power supply to the ambient lighting will be directly cut off to achieve zero power consumption and avoid energy waste.

[0090] If the above energy-saving conditions are not met (i.e., the speaker is working or the ambient light is not at an extremely high level), the core control process continues. By comparing the light intensity range of the previous moment with that of the current moment, the system decides whether to maintain the existing lighting mode or switch to a new target mode based on the comparison result, ensuring the continuous operation of intelligent dimming control in scenarios requiring ambient lighting functionality.

[0091] In one embodiment of the present invention, the step of comparing the light intensity range of the previous moment with the current light intensity range in step S30 may further include the following steps.

[0092] Obtain the driver's line of sight.

[0093] When the line of sight is directed toward the rearview mirror, and the upper limit of the current light intensity range is less than the minimum value of the preset light intensity range, the brightness of the ambient light in the current lighting mode is reduced.

[0094] Otherwise, compare the light intensity range from the previous moment with the current light intensity range.

[0095] Specifically, during the control of the vehicle's ambient lighting, the system continuously monitors the driver's gaze direction using an in-vehicle camera. When the system detects that the driver's gaze is directed towards the rearview mirror and the current ambient light intensity is in the low-light range (i.e., the upper limit of light intensity is less than or equal to 50 lux), it will immediately perform a brightness adjustment operation, actively reducing the brightness level of the ambient lights in the current lighting mode.

[0096] If the above conditions are not met simultaneously (i.e., the driver's line of sight is not directed towards the rearview mirror, or the current ambient light is not considered low light), the original core control process continues. The light intensity range of the previous moment is compared with the current light intensity range, and a decision is made based on the comparison result to switch the lighting mode, thereby ensuring that the ambient light can respond normally to changes in ambient light without needing to significantly reduce brightness.

[0097] Please see Figure 2 In one embodiment of the present invention, a vehicle ambient lighting control system 100 is also proposed, including a data acquisition unit 110, a light intensity determination unit 120, a comparison unit 130, and a control unit 140.

[0098] The acquisition unit 110 is used to continuously acquire ambient light intensity during vehicle operation.

[0099] The light intensity determination unit 120 is used to determine the light intensity interval corresponding to the ambient light intensity at the previous moment and the light intensity interval corresponding to the current ambient light intensity based on a plurality of preset light intensity intervals.

[0100] The comparison unit 130 is used to compare the light intensity range of the previous moment with the current light intensity range.

[0101] The control unit 140 is used to switch the ambient light's lighting mode when the current light intensity range is different from the current light intensity range; otherwise, it maintains the ambient light's lighting mode.

[0102] Please see Figure 3 In one embodiment of the present invention, an electronic device 200 is also proposed. The electronic device 200 may include a memory 210, a processor 220 and a bus, and may also include a computer program stored in the memory 210 and executable on the processor 220, such as a control program for vehicle ambient lighting.

[0103] The memory 210 includes at least one type of readable storage medium, such as flash memory, portable hard drive, multimedia card, card-type memory (e.g., SD or DX memory), magnetic memory, magnetic disk, optical disk, etc. In some embodiments, the memory 210 can be an internal storage unit of the electronic device 200, such as the portable hard drive of the electronic device 200. In other embodiments, the memory 210 can be an external storage device of the electronic device 200, such as a plug-in portable hard drive, smart media card (SMC), secure digital card (SD), flash card, etc., equipped on the electronic device 200. Furthermore, the memory 210 can include both internal and external storage units of the electronic device 200. The memory 210 can be used not only to store application software and various types of data installed on the electronic device 200, such as control code for vehicle ambient lighting, but also to temporarily store data that has been output or will be output.

[0104] In some embodiments, the processor 220 may be composed of integrated circuits, such as a single packaged integrated circuit or multiple integrated circuits packaged with the same or different functions, including combinations of one or more central processing units (CPUs), microprocessors, digital processing chips, graphics processors, and various control chips. The processor 220 is the control unit of the electronic device 200, connecting various components of the electronic device 200 via various interfaces and lines. It executes programs or modules stored in the memory 210 (e.g., the control program for vehicle ambient lighting) and calls data stored in the memory 210 to perform various functions and process data of the electronic device 200.

[0105] The processor 220 executes the operating system of the electronic device 200 and various installed applications. The processor 220 executes the applications to implement the steps in the above-described vehicle ambient lighting control method.

[0106] For example, the computer program may be divided into one or more modules, which are stored in the memory 210 and executed by the processor 220 to complete this application. The one or more modules may be a series of computer program instruction segments capable of performing specific functions, which describe the execution process of the computer program in the electronic device 200. For example, the computer program may be divided into a data acquisition unit 110, a light intensity determination unit 120, a comparison unit 130, and a control unit 140.

[0107] The integrated unit implemented as a software functional module described above can be stored in a computer-readable storage medium, which can be non-volatile or volatile. The software functional module, stored in the storage medium, includes several instructions to cause a computer device (which may be a personal computer, computer equipment, or network device, etc.) or processor to execute some functions of the vehicle ambient lighting control method described in the various embodiments of this application.

By continuously collecting ambient light intensity data during vehicle operation, it determines the previous ambient light intensity range and the current ambient light intensity range. The previous and current ambient light intensity ranges are compared, and if they differ, the ambient lighting mode is switched. This ensures timely adjustment of the ambient lighting, avoids safety hazards, and guarantees the visibility and comfort of the lighting effects under different ambient lighting conditions.
