[0027] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0028] In the embodiment of the present application, the inventor proposes a vehicle-mounted atmosphere light control method, device and vehicle, which triggers the generation of a brightness control instruction if the received target vehicle-mounted signal meets the preset conditions; based on the brightness control instruction, the brightness of the designated lamp bead of the vehicle-mounted atmosphere light is adjusted, and the designated lamp bead includes at least one lamp bead that projects the vehicle-mounted atmosphere light to a designated visual area, and there is a mapping relationship between the brightness of the designated lamp bead and the brightness control instruction. Thus, by adjusting the brightness of the designated lamp bead of the vehicle-mounted atmosphere light based on the brightness control instruction that has a mapping relationship with the brightness of the designated lamp bead of the atmosphere light, on the one hand, it can prevent the projection of the designated lamp bead from interfering with the user's driving vision or play a role in reminding the user of driving safety, and on the other hand, it can achieve a more accurate adjustment of the brightness of the designated lamp bead, thereby further improving driving safety.

[0029] See also Figure 1 , a vehicle-mounted atmosphere light control method provided in an embodiment of the present application, the vehicle-mounted atmosphere light control method can be applied to the field of electronic technology, specifically, can be applied to control the brightness of the atmosphere light configured inside the vehicle to ensure that the mirror projection of the atmosphere light on the vehicle window does not affect the safety of driving. The method includes:

[0030] Step S110: If the received target vehicle-mounted signal meets a preset condition, a brightness control instruction is generated.

[0031] In the implementation manner of the present application, the brightness control instruction is used to instruct the control to adjust the brightness of the vehicle ambient light. The vehicle signals include ambient light signals, backlight signals, gear signals, and blind spot detection signals. Among them, the ambient light signal may specifically include an ambient light brightness signal, an ambient light color signal, and an ambient light enable signal. The gear signal may include a READY gear signal or a P gear signal.

[0032] In one implementation, the target vehicle-mounted signal may include an ambient light signal and a backlight signal, or an ambient light signal and a gear signal (which may be a READY gear signal or a P gear signal); in another implementation, the target vehicle-mounted signal may include a blind spot detection signal.

[0033] In an embodiment of the present application, the atmosphere light controller can determine the currently received vehicle signal as the target vehicle signal. In this way, if the target vehicle signal meets the preset conditions, it can trigger the generation of a brightness control instruction to control and adjust the brightness of the atmosphere light.

[0034] Among them, different types of target vehicle-mounted signals have different corresponding preset conditions.

[0035] For example, if the target vehicle signal includes an ambient light signal and a backlight signal, when the ambient light enable signal is "ON" (i.e., the ambient light is in an enabled state), and the ambient light brightness signal and the ambient light color signal are both valid, if the backlight state is detected to be "ON", it can be determined that the received target vehicle signal meets the preset conditions, and the generation of a brightness control instruction can be triggered at this time.

[0036] If the target vehicle-mounted signal includes an ambient light signal and a gear signal (which can be a READY gear signal or a P gear signal), then when the ambient light enable signal is "ON" (that is, the ambient light is in the enabled state), and the ambient light brightness signal and the ambient light color signal are both valid, if the gear state (which can be the READY gear or the P gear) is detected to be "ON", it can be determined that the received target vehicle-mounted signal meets the preset conditions, and the generation of a brightness control instruction can be triggered at this time.

[0037] If the target vehicle signal includes a blind spot detection signal, when the blind spot detection signal is identified (or the blind spot detection signal is valid), it can be determined that the received target vehicle signal meets the preset conditions, and the brightness control instruction is triggered.

[0038] In a specific application scenario, such as Figure 2 As shown, the vehicle's body controller (IBCM) can obtain the ambient light brightness signal, ambient light color signal, ambient light enable signal, READY gear signal (provided by the vehicle's vehicle controller VCU), backlight signal and P gear signal (provided by the vehicle's shift lever module) in real time, and synchronize these signals to the ambient light controller (IAL). The ambient light controller can determine whether to trigger the generation of brightness control instructions based on the received signals.

[0039] As an implementation method, it can be determined whether to trigger the generation of a brightness control instruction according to the ambient light enable signal, the ambient light brightness signal, and the backlight signal. Figure 3 As shown, when the ambient light controller (IAL) receives the ambient light enable signal, the ambient light brightness signal, and the backlight signal, it can confirm whether the ambient light is in the on state according to the received ambient light enable signal. If it is determined that the ambient light is in the on state, it is further determined whether the backlight is in the on state according to the received backlight signal. Optionally, if the backlight is in the on state, it indicates that the surrounding environment in which the vehicle is traveling is dark. At this time, in order to avoid the mirror projection of the aforementioned ambient light interfering with the driving user's line of sight, a brightness control instruction can be triggered to trigger the adjustment of the brightness of the ambient light.

[0040] As another implementation, it can be determined whether to trigger the generation of the brightness control instruction according to the ambient light enable signal, the ambient light brightness signal and the READY position signal. Figure 4 As shown, when the ambient light controller (IAL) receives the ambient light enable signal, the ambient light brightness signal, and the READY gear position signal, it can confirm whether the ambient light is in the on state according to the received ambient light enable signal. If it is determined that the ambient light is in the on state, it is further determined whether the READY gear is in the on state according to the received READY gear position signal. Optionally, if the READY gear is in the on state, it indicates that the vehicle is about to start driving. In order to avoid the ghosting of the ambient light during driving interfering with the user's vision and affecting driving safety, the brightness control instruction can be triggered to control the brightness of the ambient light when the READY gear is detected to be on, thereby ensuring driving safety to the greatest extent.

[0041] As another implementation, it can be determined whether to trigger the generation of the brightness control instruction according to the ambient light enable signal, the ambient light brightness signal and the P gear signal. Figure 5 As shown, when the ambient light controller (IAL) receives the ambient light enable signal, the ambient light brightness signal, and the P gear signal, it can confirm whether the ambient light is in the on state according to the received ambient light enable signal. If it is determined that the ambient light is in the on state, it can further determine whether the P gear is in the on state according to the received P gear signal. Optionally, if the P gear is in the off state, it indicates that the vehicle is still driving. In order to avoid the ghost of the ambient light interfering with the user's vision and affecting driving safety during driving, the brightness control instruction can be triggered when it is detected that the vehicle is not in the P gear (that is, the P gear is off) to avoid the ghost of the ambient light affecting driving safety.

[0042] In another specific application scenario, the vehicle body can detect blind spot signals in real time. If the vehicle's rearview mirror area is not equipped with a blind spot detection indicator light, the detected blind spot signal can be sent to the ambient light controller (IAL). If the ambient light controller (IAL) recognizes that the blind spot detection signal is valid (that is, when a blind spot is detected), it can trigger the generation of a brightness control instruction.

[0043] Step S120: Based on the brightness control instruction, the brightness of the designated lamp beads of the vehicle ambient light is adjusted, and the designated lamp beads include at least one lamp bead that projects the vehicle ambient light onto the designated visual area, and there is a mapping relationship between the brightness of the designated lamp bead and the brightness control instruction.

[0044] When a brightness control instruction is generated, the brightness of the vehicle ambient light can be adjusted based on the brightness control instruction.

[0045] It is understandable that the center console and the inner side of the door of the vehicle can be equipped with ambient lights, and the number of ambient lights inside the vehicle can be unlimited, for example, it can be one or more. Figure 6 , shows an example diagram of the atmosphere light inside a vehicle provided by an embodiment of the present application. Figure 6 As shown, two ambient lights of different lengths are arranged on both sides of the center console of the vehicle. Although the vehicle ambient lights can improve the comfort of the riding environment and increase the personalized configuration of the vehicle, if a large area of ​​ambient lights are arranged inside the vehicle, when the driving environment of the vehicle is dark, such as driving at night, a mirror projection of the vehicle ambient lights will be formed on the side windows or windshield of the vehicle. Among them, the mirror projection of the ambient light on the side window of the vehicle may intersect (intersect) with the rearview mirror, which to a certain extent blocks the user from viewing the rearview mirror, thereby affecting driving safety; and the mirror projection on the windshield of the vehicle is also easy to block the user from viewing the driving road conditions, thereby causing traffic accidents.

[0046] In a specific application scenario, see Figure 7 , shows an example diagram of the projection of the ambient light provided by the embodiment of the present application on the side window of the vehicle overlapping with the rearview mirror. Figure 7 As shown in the figure, there will be a ghost image of the ambient light in some areas of the rearview mirror. After enlarging the ghost image of the ambient light, the following can be obtained: Figure 8 The following is an example of overlapping relationships. Figure 8 As shown in FIG. 1 , with the vehicle side window as a reference, the imaging area of ​​the ambient light projected on the vehicle side window will overlap with the visual area of ​​the exterior rearview mirror (i.e., the visual area of ​​the exterior rearview mirror viewed through the vehicle window). The overlapping portion is shown in FIG. Figure 8 As shown by the shaded area, the area of ​​the overlapping portion may also change as the brightness of the vehicle's driving environment changes.

[0047] Therefore, if the overall brightness of the ambient light is controlled and adjusted, it may not be possible to specifically solve the problem of the ambient light affecting driving safety, and hardware resources will be wasted to a certain extent.

[0048] Therefore, the embodiment of the present application can control and adjust the brightness of a specified lamp bead of the vehicle-mounted ambient light, and the specified lamp bead can be understood as at least one lamp bead of the vehicle-mounted ambient light projecting an image to a specified visual area (for example, the specified lamp bead can be Figure 8 The designated sight area may be a rearview mirror area or a front windshield area of ​​the vehicle, or the designated sight area includes the rearview mirror area and the front windshield area of ​​the vehicle. For example, see Fig. 9 , shows an example diagram of the structure of the atmosphere lamp provided by the embodiment of the present application, including a plurality of lamp beads. Fig. 9As shown in FIG. 1 , the atmosphere lamp includes n lamp beads. Fig.10 It can be seen that some of the lamp beads of the ambient light (i.e., multiple lamp beads of the specified ambient light) will actually produce a double image with the sight area of ​​the exterior rearview mirror. For example, Fig.10 The lamp beads D1, D2, and D3 in the image will produce ghost images with the sight area of ​​the exterior rearview mirror, while other lamp beads (such as lamp bead D4) will not produce ghost images with the sight area of ​​the exterior rearview mirror. Therefore, in order to improve the intelligence and fun of the ambient light control, only the brightness of the lamp beads D1, D2, and D3 can be adjusted. By reducing the control objects, computing resources can be saved, and the control efficiency of the vehicle-mounted ambient light can be improved to a certain extent.

[0049] At the same time, in order to facilitate more refined adjustment of the brightness of the specified lamp bead, there can be a mapping relationship between the brightness of the specified lamp bead and the brightness control instruction. The mapping relationship can be preset according to actual needs, and the mapping relationship between the brightness control instruction generated under different trigger conditions and the brightness of the specified lamp bead can be different, or can be the same, without specific limitation.

[0050] The present embodiment provides a method for controlling a vehicle-mounted atmosphere light, which generates a brightness control instruction by triggering the generation of a brightness control instruction if the received target vehicle-mounted signal meets a preset condition; based on the brightness control instruction, the brightness of a designated lamp bead of the vehicle-mounted atmosphere light is adjusted, and the designated lamp bead includes at least one lamp bead that projects an image of the vehicle-mounted atmosphere light to a designated sight area, and there is a mapping relationship between the brightness of the designated lamp bead and the brightness control instruction. The present method adjusts the brightness of the designated lamp bead of the vehicle-mounted atmosphere light based on a brightness control instruction that has a mapping relationship with the brightness of the designated lamp bead of the atmosphere light. On the one hand, it can prevent the projection of the designated lamp bead from interfering with the user's driving sight or serving to remind the user of driving safety, and on the other hand, it can achieve a more accurate adjustment of the brightness of the designated lamp bead, thereby further improving driving safety.

[0051] See also Fig.11 , is another embodiment of the present application providing a method for controlling a vehicle ambient light, the method comprising:

[0052] Step S210: If the received target vehicle-mounted signal meets a preset condition, a brightness control instruction is generated.

[0053] The specific implementation of step S210 may refer to the relevant description of step S110 in the aforementioned embodiment, which will not be repeated here.

[0054] Step S220: Determine the instruction type of the brightness control instruction.

[0055] In the implementation manner of the present application, the instruction type of the brightness control instruction can be determined according to the type of the target vehicle-borne signal. Different types of target vehicle-borne signals correspond to different instruction types of the brightness control instruction.

[0056] In the process of determining the instruction type of the brightness control instruction, as an implementation mode, if the target vehicle-mounted signal is an ambient light signal and a backlight signal, or the target vehicle-mounted signal is an ambient light signal and a gear signal, then the brightness control instruction is determined to be a first instruction type; if the target vehicle-mounted signal is a blind spot detection signal, then the brightness control instruction is determined to be a second instruction type.

[0057] Step S230: determining a corresponding brightness adjustment method according to the instruction type, where different instruction types correspond to different brightness adjustment methods.

[0058] In this embodiment, in order to be able to adjust the brightness of a specified lamp bead in a targeted manner, the corresponding brightness adjustment method can be determined according to the instruction type of the brightness control instruction, wherein different instruction types correspond to different brightness adjustment methods, and then the brightness of the specified lamp bead is adjusted according to the brightness adjustment method.

[0059] Step S240: adjusting the brightness of the designated lamp beads of the vehicle ambient light according to the brightness adjustment method.

[0060] In this embodiment, the corresponding brightness adjustment method is determined according to the instruction type, and the brightness of the designated lamp beads of the vehicle atmosphere light is adjusted according to the brightness adjustment method, including: if the brightness control instruction is the first instruction type, the brightness can be controlled to be lowered as the corresponding brightness adjustment method, and then the brightness of the designated lamp beads of the vehicle atmosphere light is lowered; and if the brightness control instruction is the second instruction type, the brightness can be controlled to be increased as the corresponding brightness adjustment method, and then the brightness of the designated lamp beads of the vehicle atmosphere light is increased.

[0061] That is to say, if the brightness control command is generated based on the ambient light signal and the backlight signal, or the ambient light signal and the gear signal meet the preset conditions, then in order to avoid the projection of the ambient light on the side windows of the vehicle affecting the user's driving safety, the brightness of the designated lamp beads will be controlled to be lowered; if the brightness control command is generated based on the blind spot detection signal, in order to avoid the vehicle's blind spot affecting the user's driving safety, the brightness of the designated lamp beads will be controlled to be increased, so as to remind the user of the blind spot in the current road conditions through the ambient light with increased brightness, thereby further ensuring the user's driving safety.

[0062] It should be noted that, in the implementation manner of the present application, lowering the brightness of designated lamp beads of the vehicle atmosphere light may specifically include: lowering the brightness of designated lamp beads of the vehicle atmosphere light or turning off the designated lamp beads of the vehicle atmosphere light.

[0063] Among them, turning off the specified lamp bead can be understood as switching the specified lamp bead from the on state to the off state. In this way, the brightness value of the specified lamp bead is 0. This method can completely eliminate the interference of the projection of the ambient light on the side windows of the vehicle and other positions on the user's line of sight, thereby better solving the problem of the projection of the ambient light affecting driving safety.

[0064] Lowering the brightness of a specified lamp bead can be understood as adjusting the brightness of the specified lamp bead from the current brightness to a lower brightness.

[0065] By turning off only the multiple lamp beads that will produce ghosting with the rearview mirror (or other designated visual areas) or lowering the brightness of the multiple lamp beads, the intelligence of the ambient light control can be improved; by controlling the ambient light to act as a blind spot detection indicator light, the fun of the ambient light control is enhanced, thereby improving the user experience.

[0066] The present embodiment provides a method for controlling a vehicle atmosphere light, which generates a brightness control instruction by triggering it if the received target vehicle signal meets a preset condition; determines the instruction type of the brightness control instruction; determines the corresponding brightness adjustment method according to the instruction type, and different instruction types correspond to different brightness adjustment methods; and adjusts the brightness of a designated lamp bead of the vehicle atmosphere light according to the brightness adjustment method, wherein the designated lamp bead includes at least one lamp bead that projects an image of the vehicle atmosphere light to a designated visual area, and there is a mapping relationship between the brightness of the designated lamp bead and the brightness control instruction. The present method adjusts the brightness of the designated lamp bead of the vehicle atmosphere light based on a brightness control instruction that has a mapping relationship with the brightness of the designated lamp bead of the atmosphere light. On the one hand, it can prevent the projection of the designated lamp bead from interfering with the user's driving visual line or serving to remind the user of driving safety, and on the other hand, it can achieve more accurate adjustment of the brightness of the designated lamp bead, thereby further improving driving safety.

[0067] At the same time, by setting different ambient light brightness adjustment logics, the flexibility and intelligence of ambient light control can be improved.

[0068] See also Fig.12 , is a vehicle-mounted ambient light control method provided by another embodiment of the present application, the method comprising:

[0069] Step S310: If the received target vehicle-mounted signal meets a preset condition, a brightness control instruction is generated.

[0070] The specific implementation of step S310 may refer to the relevant description of step S110 in the aforementioned embodiment, which will not be repeated here.

[0071] Step S320: Based on the brightness control instruction, at least one of the first parameter and the second parameter is adjusted to adjust the brightness of the designated lamp beads of the vehicle atmosphere light, the designated lamp beads include at least one lamp bead that projects the vehicle atmosphere light onto a designated visual area, and there is a mapping relationship between the brightness of the designated lamp beads and the brightness control instruction.

[0072] In an implementation manner of the present application, the mapping relationship includes a function correspondence relationship, and the function includes a first parameter and a second parameter. As an implementation manner, at least one of the first parameter and the second parameter can be adjusted based on a brightness control instruction to adjust the brightness of a specified lamp bead of the vehicle atmosphere light.

[0073] Optionally, the function correspondence may be a linear function correspondence, a quadratic function correspondence, or other types of function correspondences, and the specific function type may not be limited.

[0074] In a specific implementation, taking the above-mentioned function correspondence as a linear function as an example, if the linear function is expressed as: y=kx+b, then the first parameter can be k (or b), and the second parameter can be b (or k). In this way, at least one of k or b can be adjusted to adjust the brightness of the specified lamp bead of the vehicle ambient light.

[0075] In the implementation manner of the present application, the brightness of the designated lamp bead can be configured as multiple brightness modes, and the brightness control instructions of the vehicle-mounted ambient light can also be divided into multiple levels, wherein the brightness of the designated lamp bead in each brightness mode can be divided into multiple brightness levels, and each brightness level includes multiple brightness values. When the brightness mode is determined (i.e., in the same brightness mode), different brightness control instructions correspond to different brightness levels; and in different brightness modes, different brightness control instructions correspond to different brightness levels, so that in the process of adjusting the brightness of the designated lamp bead, the brightness mode can be determined first, and then the corresponding brightness adjustment coefficient (i.e., brightness adjustment amount) can be further determined according to the determined brightness mode.

[0076] Specifically, as an implementation, the process of adjusting at least one of the first parameter and the second parameter may include: determining a brightness mode corresponding to the brightness control instruction; determining an adjustment amplitude for adjusting at least one of the first parameter and the second parameter according to the brightness mode, different brightness modes corresponding to different adjustment amplitudes; and adjusting at least one of the first parameter and the second parameter based on the adjustment amplitude.

[0077] In this embodiment, the brightness mode of the ambient light may include a normal mode (i.e., normal brightness) and a low brightness mode (brightness lower than normal brightness). The low brightness mode may be divided into multiple levels of low brightness modes according to actual needs. For example, the low brightness mode may include low brightness mode 1 and low brightness mode 2. For example, see Fig.13 , shows an example diagram of the linear function correspondence between the brightness of a specified lamp bead and the brightness control instruction in different brightness modes provided by the embodiment of the present application. Fig.13 As shown, the ambient light can have multiple brightness modes, and the functional relationships in different brightness modes are different. In each brightness mode, different brightness control instructions correspond to different brightness of the vehicle ambient light.

[0078] In the process of determining the brightness mode corresponding to the brightness control instruction, when the brightness control instruction is generated, the current brightness value is also identified to determine the brightness mode corresponding to the brightness control instruction according to the brightness control instruction and the current brightness value. Fig.13 In the case of the brightness control instruction 4 shown, if the current brightness value is 159, it can be determined that the brightness mode corresponding to the brightness control instruction is the normal brightness mode; if the current brightness value is 79, it can be determined that the brightness mode corresponding to the brightness control instruction is the low brightness mode 1; if the current brightness value is 39, it can be determined that the brightness mode corresponding to the brightness control instruction is the low brightness mode 2.

[0079] When the brightness mode is determined, the adjustment range of at least one of the first parameter and the second parameter can be determined according to the brightness mode. Fig.13 The brightness difference between two adjacent levels of brightness values ​​in the normal mode shown is 32, while the brightness difference between two adjacent levels of brightness values ​​in low brightness mode 1 is 16, and the brightness difference between two adjacent levels of brightness values ​​in low brightness mode 2 is 8. This brightness difference can be understood as the adjustment range.

[0080] It should be noted that this adjustment amplitude represents the adjustment amount of the brightness of the specified lamp bead, not the adjustment amount of the first parameter or the second parameter. At this time, the brightness of the atmosphere light can be adjusted by adjusting the first parameter and / or the second parameter.

[0081] In the process of adjusting at least one of the first parameter and the second parameter based on the adjustment amplitude, the specific numerical values ​​of the first parameter and / or the second parameter can be randomly changed and adapted, and the positive and negative values ​​of the first parameter and / or the second parameter can be not limited.

[0082] In the process of lowering the brightness of a specified lamp bead, if the brightness mode is not switched, the brightness of the specified lamp bead can be directly lowered to the brightness corresponding to the brightness control instruction. Fig.13 In the case where the ambient light is in low brightness mode 1, if the brightness control instruction is 6, the brightness of the specified lamp bead needs to be reduced to 111.

[0083] Optionally, in the process of lowering the brightness of designated lamp beads, if the multiple lamp beads after the brightness adjustment still interfere with the user's sight, the brightness of the multiple lamp beads can be further adjusted, which involves the switching of brightness modes. Among them, the user can determine whether the multiple lamp beads after the brightness adjustment will interfere with the sight, or can use the camera to collect images and identify them to confirm whether the multiple lamp beads after the brightness adjustment will interfere with the sight. In the process of continuing to adjust the brightness of multiple lamp beads, continuing with the above example, the brightness of the multiple lamp beads can be adjusted from 255 to 111 (at this time the brightness mode changes from the normal mode to the low brightness mode 1), and further, if there is still an impact, continue to adjust to 55 (at this time the brightness mode changes from the low brightness mode 1 to the low brightness mode 2). It should be noted that the above example is only used to illustrate the implementation principle of brightness adjustment, and does not constitute a limitation on the solution. For example, in actual implementation, the brightness mode can be set to be higher than 111. Fig.13 There are more modes, and each brightness control instruction corresponds to a brightness value in a different brightness mode and can be set according to actual needs, which is not limited here.

[0084] It is worth noting that in the same brightness mode, the brightness difference between two adjacent brightness levels is the same. For example, in the normal brightness mode, the brightness difference between brightness value 255 and brightness value 223 is 32, and the brightness difference between brightness value 223 and brightness value 191 is also 32; while in different brightness modes, the brightness difference between two adjacent brightness levels is different. For example, in the normal mode, the brightness difference between two adjacent brightness levels is 32, while in low brightness mode 1, the brightness difference between two adjacent brightness levels is 16, and in low brightness mode 2, the brightness difference between two adjacent brightness levels is 8.

[0085] Optionally, this embodiment may not limit the number of times the brightness of the designated lamp beads of the vehicle-mounted atmosphere light is reduced. Exemplarily, in the case of reducing the brightness of the designated lamp beads based on the brightness control instruction, the brightness of the designated lamp beads may be first reduced from the first brightness to the second brightness, and if it still interferes with the user's sight after being reduced to the second brightness, the brightness of the designated lamp beads may be further reduced from the second brightness to the third brightness, until the projection effect of the designated lamp beads does not affect driving safety, the third brightness is less than the second brightness, and the difference between the third brightness and the second brightness is equal to the difference between the second brightness and the first brightness, that is, (third brightness - second brightness) = (second brightness - first brightness).

[0086] The present embodiment provides a method for controlling an in-vehicle atmosphere light, which triggers the generation of a brightness control instruction if the received target in-vehicle signal meets a preset condition; based on the brightness control instruction, at least one of the first parameter and the second parameter is adjusted to adjust the brightness of a designated lamp bead of the in-vehicle atmosphere light, wherein the designated lamp bead includes at least one lamp bead that projects an image of the in-vehicle atmosphere light to a designated visual area, and a mapping relationship exists between the brightness of the designated lamp bead and the brightness control instruction. The present method adjusts the brightness of the designated lamp bead of the in-vehicle atmosphere light based on a brightness control instruction that has a mapping relationship with the brightness of the designated lamp bead of the atmosphere light. On the one hand, it can prevent the projection of the designated lamp bead from interfering with the user's driving visual line or serving to remind the user of driving safety, and on the other hand, it can achieve a more accurate adjustment of the brightness of the designated lamp bead, thereby further improving driving safety.

[0087] At the same time, by turning off only the multiple lamp beads that will produce ghosting with the rearview mirror (or other designated visual areas) or lowering the brightness of the multiple lamp beads, the intelligence of the ambient light control can be improved; by controlling the ambient light to act as a blind spot detection indicator light, the fun of the ambient light control is enhanced, thereby improving the user experience.
