[0043] As shown in FIG. 1, Figure 1 The embodiments of the present application provide a control method S100 of interior light of a vehicle, which can include steps S110-S130.

[0044] In step S110, the distribution position of the passengers in the vehicle in a preset scene is identified, wherein the distribution position of the passengers can include a first position where the passengers exist and a second position where the passengers do not exist.

[0045] In an embodiment, the preset scene can include when the whole vehicle is unlocked, when the whole vehicle is locked, when the door of the vehicle is opened, and when the door of the vehicle is closed. That is, the distribution position of the passengers in the vehicle is identified after each whole vehicle unlocking or whole vehicle locking, and the passenger information in the vehicle is reconfirmed after each door opening or door closing, so that the change of the passengers in the vehicle caused by the passengers getting on or off the vehicle during driving is detected.

[0046] In step S110, the passenger distribution position of the vehicle in the preset scene can be identified by one or more of the following: image recognition, pressure sensor on the seat, seat belt reminder module, passenger detection system, and member classification sensor, etc. Specifically, in the case of identifying the passenger distribution position of the vehicle in the preset scene by the image recognition technology, step S110 can include steps S111-S113:

[0047] In step S111, a first panoramic image of the interior of the vehicle in the preset scene is acquired.

[0048] In step S112, the first panoramic image is compared with a second panoramic image of the interior of the vehicle in the state without passengers to identify whether there is portrait information in each of the plurality of positions of the vehicle. Figure 2 The interior of the vehicle can be panoramic photographed by an in-vehicle camera to acquire the first panoramic image. The in-vehicle camera can be installed on the interior rearview mirror or near the front roof light on the roof, so as to ensure that the photographed panoramic image of the interior of the vehicle can include the driver, the front passenger, and the rear passenger seating area.

[0049] In step S112, the first panoramic image is compared with a second panoramic image of the interior of the vehicle in the state without passengers to identify whether there is portrait information in each of the plurality of positions of the vehicle.

[0050] In step S112, the first panoramic image is compared with a second panoramic image of the interior of the vehicle in the state without passengers to identify whether there is portrait information in each of the plurality of positions of the vehicle. Figure 2 The image processing module can compare the image photographed by the camera with the second panoramic image (for example, a standard image pre-stored in the module). The standard image is a panoramic image of the interior of an empty vehicle. The portrait and position information can be obtained by image matting, and the two information can be converted and output. The plurality of positions of the vehicle can include the driver position, the front passenger position, the second-row position, and the third-row position.

[0051] In step S113, the position with the portrait information is determined as the first position, and the position without the portrait information is determined as the second position.

[0052] Thus, the passenger position quantity information can be acquired, and the passenger distribution position in the vehicle can be identified.

[0053] In addition, the passenger distribution position in step S110 can also be determined by collecting the seat belt reminder module, the passenger detection system (ODS), or the member classification sensor (OCS). For details, refer to the working principle shown in Figure 3 When the body controller (BCM) outputs the vehicle unlocking and locking signal and the whole vehicle power-on signal, the number and position of the passengers are confirmed by the seat belt reminder module, the ODS, or the OCS information detected by the airbag module (ACU). It can be seen that the above-mentioned method can also acquire the passenger position quantity information, so as to identify the passenger distribution position in the vehicle.

[0054] In addition, after the occupant distribution position is identified by steps S111-S113, the identified occupant distribution position can be further verified. To achieve this purpose, step S110 can further include steps S114-S115:

[0055] Step S114, detecting whether a verification control instruction is received within a first set time; and

[0056] Step S115, in the case that the verification control instruction is received within the first set time, updating the occupant distribution position and generating an error code in response to the verification control instruction.

[0057] In an embodiment, the verification control instruction can include a touch instruction, a language instruction or a gesture instruction. For example, the occupant distribution position can be first displayed through an in-vehicle central control display screen, the first set time can be the time for the in-vehicle central control display screen to display the occupant distribution position, which can be set according to actual application, for example, 3-15 seconds, which can be preferably set to 5 seconds. In another embodiment, the occupant distribution position can also be broadcasted through a voice broadcast device in the vehicle, or illuminated through a physical button in the vehicle.

[0058] The in-vehicle central control display screen can be used to display the state of the vehicle, and the passenger can control some functions of the vehicle through the central control display screen. In the present application, the in-vehicle occupant distribution position information can be displayed on the central control display screen in the form of Figure 4 The icon is composed of a plurality of buttons, which are the main driver, the co-driver, the second row and the third row, respectively, corresponding to the main driver position, the co-driver position, the second row position and the third row position of the vehicle. For example, if the main driver position is detected to have a person, the "main driver" icon on the left upper side of the central control display screen will be illuminated, and the other icons will be dimmer than the "main driver" icon. The specific partition is not limited to this, and can be selected according to the actual distribution of the ambient light and its function. Figure 4

[0059] Specifically, the central control module sends the occupant position number information to the in-vehicle central control display screen, for example, displays it on the screen for 5 seconds. If the driver does not operate during the display process, i.e., the system does not receive an input instruction within the set time, the in-vehicle central control display screen automatically confirms the in-vehicle occupant number and position information according to the illuminated area of the display. Then, a control instruction for turning on the light can be generated according to the first position in the occupant distribution position, and a control instruction for turning off the light can be generated according to the second position in the occupant distribution position.

[0060] ​As in the display process, the driver can operate the symbols on the screen to change the area that needs to be lit, that is, the driver can manually control the lighting and extinguishing of each key to output a touch instruction; or can issue a voice instruction by speaking; or can issue a gesture instruction by waving a hand. The in-vehicle central control display screen detects the above input instructions through a touch screen, a microphone, or a camera. In this case, the central control display screen updates the occupant distribution position in response to the input instruction, and thus the number and position information of the in-vehicle occupants is determined. Then, a control instruction for turning on the light can be generated according to the first position in the updated occupant distribution position, and a control instruction for turning off the light can be generated according to the second position in the updated occupant distribution position.

[0061] In an embodiment, updating the occupant distribution position can include converting one or more first positions to second positions, converting one or more second positions to first positions, converting all first positions to second positions at once, and converting all second positions to first positions at once. That is, one or more occupant distribution positions can be added, one or more occupant distribution positions can be deleted, all occupant distribution positions can be turned on, and all occupant distribution positions can be turned off.

[0062] To implement the above one-key conversion function, as shown in Figure 4 the central control screen can further include a "synchronization" key. When the "synchronization" key is lit, all vehicle lights are turned on, and when the "synchronization" key is extinguished, all vehicle lights are turned off.

[0063] In embodiments in which the occupant distribution position is identified and determined by other means, the above steps S121-S123 can also be performed. Specifically, for example, as shown in Figure 3 the ACU inputs the number and position information of the occupants to the ambient light controller and the HU, the ambient light controller sends the occupant position number information to the in-vehicle central control display screen, and displays it on the screen for 5 seconds. During the display process, the driver can operate the symbols on the screen to change the area that needs to be lit. If the driver does not operate during the display process, the system proceeds to the next step according to the displayed lighting area. Thus, the number and position information of the in-vehicle occupants is determined. In addition, the driver can also manually control the lighting and extinguishing of each key. When the "synchronization" key is lit, all vehicle lights are turned on, and when the "synchronization" key is extinguished, all vehicle lights are turned off.

[0064] The step S114-S115 is to check the passenger distribution position determined in the step S111-S113 by checking the control instruction. If the check fails, the passenger distribution position needs to be updated and an error code is generated to remind the user that the above information recognition is wrong. The occasional check may be due to complex scenes such as dim light, but if the error code appears many times, it may be that the passenger distribution position recognition device of the vehicle is malfunctioning and needs to be repaired.

[0065] In addition, after determining and checking the passenger distribution position by the step S110, the checked passenger distribution position can also be manually intervened. That is, the passenger distribution position determined and checked by the step S110 is not wrong, but the user still needs to make personalized adjustments to the passenger distribution position.

[0066] Therefore, after the step S110, the control method S100 of the present application can further include the following steps:

[0067] 1) detecting whether an intervention control instruction is received within a second set time;

[0068] 2) in the case where the intervention control instruction is received within the second set time, updating the passenger distribution position in response to the intervention control instruction and storing the intervention control instruction; and

[0069] 3) generating user preference information according to the stored intervention control instruction to automatically intervene in the passenger distribution position by the user preference information.

[0070] In an embodiment, the intervention control instruction can include a touch instruction, a language instruction or a gesture instruction. For example, the passenger distribution position can be first displayed through the in-vehicle central control display screen, and the second set time can be the time for the in-vehicle central control display screen to display the passenger distribution position. It can also be set according to actual application, for example, 3-15 seconds, which can be preferably set to 5 seconds. In addition, the second set time can be after the first set time, for example, the first set time is 0-5 seconds, and the second set time is 5-10 seconds. In addition, since the failure of the recognition system is a small probability event, the second set time can be longer than the first set time, for example, the first set time is 0-3 seconds, and the second set time is 3-8 seconds.

[0071] In another embodiment, the passenger distribution position can also be announced by the in-vehicle voice broadcast device or illuminated by the in-vehicle physical button.

[0072] In an embodiment, updating the occupant distribution position can include converting one or more first positions to second positions, converting one or more second positions to first positions, converting all first positions to second positions at one key, and converting all second positions to first positions at one key. That is, one or more occupant distribution positions can be added, one or more occupant distribution positions can be deleted, all occupant distribution positions can be turned on, and all occupant distribution positions can be turned off. In addition, other specific embodiments can be referred to steps S114-S115.

[0073] The above steps are to intervene in the occupant distribution position determined in step S110 through the intervention control instruction. If the user intervenes, it indicates that the user has personalized needs for the occupant distribution position. Therefore, the intervention control instruction can be stored, and user preference information can be generated according to the stored intervention control instruction to automatically intervene in the occupant distribution position through the user preference information. Among them, the intervention that occurs accidentally can be due to the user's temporary intention, etc., but if the user intervenes multiple times, it can be the user's preference. In order to further improve the user experience, the user preference information can be intelligently generated in a machine learning manner according to the content and frequency of the stored intervention control instruction. In this way, after the occupant distribution position is identified and checked subsequently, the occupant distribution position can be automatically intervened through the user preference information, so that the occupant distribution position can be adjusted to the user's habit mode without user operation, improving the automation and intelligence of the car-machine interaction and optimizing the user experience.

[0074] In step S120, a light control instruction is generated according to the occupant distribution position. The light control instruction causes the light corresponding to the first position to be in an on state and the light corresponding to the second position to be in an off state.

[0075] The light control instruction can be implemented by the central control module to control the whole vehicle light software module, and at the same time, the central control module can interact with the in-vehicle central control display screen, so as to feed back and display the lighting state of the whole vehicle atmosphere lamp on the central control display screen. The passenger can also operate the lighting state of the whole vehicle atmosphere lamp through the central control display screen.

[0076] The light control instruction causes the light corresponding to the first position to be in an on state, which includes adjusting the light in the off state at the first position to the on state, and maintaining the light in the on state at the first position to the on state. Similarly, the light control instruction causes the light corresponding to the second position to be in an off state, which includes adjusting the light in the on state at the second position to the on state, and maintaining the light in the off state at the second position to the off state.

[0077] Step S130, executing the light control instruction, so that the light of the first position is in an open state, and the light of the second position is in a closed state.

[0078] The interior light of the vehicle can include an ambient light and / or a reading light. It is worth noting that the ambient light and the reading light in the present application can adopt various forms of ambient light and reading light in actual application. In an embodiment, the light-emitting form of the ambient light and the reading light can include one or more of the following: a point light source, a surface light source, a reflective light guide bar, and a direct light guide bar.

[0079] The function of step S130 can be realized by a light control module, for example, an ambient light controller. The ambient light controller can be a separate controller arranged near the instrument panel, or can be integrated with other controllers (such as a BCM or a HU) of the vehicle. After determining the position information of the vehicle occupants, the ambient light controller and the BCM can control the opening and closing of each ambient light through LIN communication or CAN communication. For the area without occupants, the ambient light controller closes the corresponding ambient light and reading light.

[0080] The present application has the following advantages without affecting the traditional operation mode:

[0081] 1) The present application provides a scheme for automatically determining the number and position of vehicle occupants through image recognition technology. The number and position of vehicle occupants can also be manually confirmed and changed through the central control display screen.

[0082] 2) The present application provides a vehicle interior area distinguishing display icon and control system, which can realize automatic independent opening or closing of the ambient light in multiple areas of the vehicle, increase the sense of technology of the automobile, and make the automobile more intelligent.

[0083] 3) The present application can reduce the load of the interior light system of the vehicle while ensuring the atmosphere and lighting needs of the ambient light, save energy consumption, and especially for electric vehicles, save electric energy to increase the driving range.

[0084] 4) The present application can also be used in more number and function ambient lights, and the principle is the same, only the number of areas and corresponding number is increased.

[0085] On the other hand, the present application also provides a control system 200 of the interior light of a vehicle, as shown in Figure 5 The control system can include:

[0086] An identification device 210 for identifying the distribution position of the occupants of the vehicle in a preset scene, wherein the distribution position of the occupants can include a first position where the occupants exist and a second position where the occupants do not exist.

[0087] The central control module 220 is configured to generate a light control instruction according to the passenger distribution position, wherein the light control instruction causes the light corresponding to the first position to be in an open state and the light corresponding to the second position to be in a closed state; and

[0088] The light control module 230 is configured to execute the light control instruction.

[0089] In an embodiment, the preset scene can include: when the whole vehicle is unlocked, when the whole vehicle is locked, when the vehicle door is opened, and when the vehicle door is closed. That is, the passenger distribution position of the vehicle is identified after each whole vehicle unlocking or whole vehicle locking, and the in-vehicle passenger information is reconfirmed after each vehicle door opening or vehicle door closing, so that the in-vehicle passenger change caused by the passenger getting on or off during driving is detected.

[0090] The light control module 230 can be an ambient light controller configured to control the whole vehicle ambient light system and the reading light assembly. The ambient light controller can be a separate controller arranged near the instrument panel, or can be integrated with other controllers (such as BCM or HU) of the whole vehicle. After determining the in-vehicle passenger position information, the ambient light controller and the BCM can control the opening and closing of each ambient light through LIN communication or CAN communication. For the area without passengers, the ambient light controller turns off the corresponding ambient light and reading light. It is worth noting that the ambient light and reading light in the present application can adopt various forms of ambient light and reading light actually applied. In an embodiment, the light-emitting form of the ambient light and the reading light can include one or more of the following: point light source, area light source, reflective light guide bar, and direct light guide bar.

[0091] In an embodiment of the whole vehicle ambient light system, the relationship between the in-vehicle areas and the corresponding reading lights is as shown in Figure 6 The whole vehicle ambient light and the ambient light controller can include: 1-instrument ambient light, 2-front door ambient light, 3-rear door ambient light, 4-rear side ambient light; 5-two-row seat ambient light, 6-three-row footstep ambient light, 7-front-row seat ambient light, 8-two-row footstep ambient light, 9-front-row footstep ambient light, and 10-ambient light controller. The in-vehicle areas and the corresponding reading lights can include: 11-front-row reading light, 12-two-row reading light, and 13-three-row reading light.

[0092] In addition, in the reading light assembly, the control flow chart is as shown in Figure 7

[0093] ​The identification device 210 can include one or more of an image processing module, a seat belt reminder module, an occupant detection system (ODS), and an occupant classification sensor (OCS). That is, the occupant distribution position can be identified by image recognition technology, and the occupant distribution position can also be identified by collecting the seat belt reminder module, the ODS, or the OCS.

[0094] In the case of identifying the occupant distribution position by the image processing module, the image processing module can include a camera unit, an image comparison unit, and an image analysis unit.

[0095] The camera unit is configured to take a panoramic picture of the interior of the vehicle to obtain a first panoramic image of the interior of the vehicle in a preset scene. In an embodiment, referring to Figure 8 , the camera unit can be an in-vehicle camera, which can be installed on the interior rearview mirror or near the front roof light on the ceiling, to ensure that the captured panoramic picture of the interior of the vehicle includes the driver, the front passenger, and the rear passenger seating area.

[0096] The image comparison unit is configured to compare the first panoramic image with a second panoramic image of the interior of the vehicle in an empty state, for example, to compare the first panoramic image with a preset empty vehicle image to identify whether there is portrait information at each of a plurality of positions in the vehicle. Referring to Figure 8 The image comparison unit can compare the picture captured by the camera with a preset empty vehicle image (for example, a standard picture pre-stored in the module). The standard picture is a panoramic picture of the interior of an empty vehicle. The portrait and position information can be obtained by image matting and converted and output. The plurality of positions in the vehicle can include the driver position, the front passenger position, the second-row position, and the third-row position.

[0097] The image analysis unit is configured to determine a position with portrait information as a first position and a position without portrait information as a second position. Thus, the number of occupant positions can be obtained to identify the occupant distribution position in the vehicle.

[0098] The in-vehicle occupant number and position determination system includes a BCM, an in-vehicle camera, an image processing module, and an in-vehicle central control display screen. The specific working principle is as follows: after the BCM sends a vehicle unlocking and locking signal and the entire vehicle is powered on, the in-vehicle camera starts to take a panoramic picture of the interior of the vehicle, the image processing unit compares and analyzes the captured image with the stored image, and outputs the number and position information of the in-vehicle occupants to the ambient light controller and the BCM,

[0099] In addition, referring to Figure 9The passenger distribution position can also be determined by collecting the seat belt reminder module, ODS or OCS. When the BCM sends a vehicle unlocking or locking signal or a vehicle power-on signal, the number and position of the passengers are confirmed by the information of the seat belt reminder module, ODS or OCS detected by the ACU. It can be seen that the above-mentioned method can also obtain the passenger position number information, so as to identify the passenger distribution position in the vehicle.

[0100] In an embodiment, the checking control instruction can include a touch instruction, a language instruction or a gesture instruction. For example, the passenger distribution position can be first displayed on the in-vehicle central control display screen. The first set time can be the time for the display screen to display the passenger distribution position. The actual application can be set, for example, 3-15 seconds, which can be preferably set to 5 seconds. In another embodiment, the passenger distribution position can also be broadcast by the in-vehicle voice broadcast device, or the passenger distribution position can be lit by the in-vehicle physical button.

[0101] The in-vehicle central control display screen can be used to display the vehicle state, and the passenger can control some functions of the vehicle through the central control display screen. In the present application, the in-vehicle passenger distribution position information can be displayed on the central control display screen in the form of Figure 4 The icon is composed of a plurality of keys, which are the main driver, the co-driver, the second row and the third row, respectively. They correspond to the main driver position, the co-driver position, the second row position and the third row position of the vehicle, respectively. For example, if there is a person in the main driver position, the "main driver" icon on the left upper side of the central control module will be lit, and the other icons will be darker than the "main driver" icon. The specific partition is not limited to this, and can be selected according to the actual distribution of the atmosphere lamp and its function. Figure 4

[0102] Specifically, the central control module sends the passenger position number information to the in-vehicle central control display screen, for example, displays it on the screen for 5 seconds. If the driver does not operate during the display process, that is, the system does not receive an input instruction within the set time, the in-vehicle central control display screen automatically confirms the number and position of the passengers in the lighted area displayed. Then, the control instruction for turning on the light can be generated according to the first position in the passenger distribution position, and the control instruction for turning off the light can be generated according to the second position in the passenger distribution position.

[0103] ​As in the display process, the driver can operate the symbols on the screen to change the area that needs to be lighted, that is, the driver can manually control the lighting and extinguishing of each key to output a touch instruction; or can issue a voice instruction by speaking; or can issue a gesture instruction by waving a hand. The in-vehicle central control display screen detects the above input instructions through a touch screen, a microphone or a camera. In this case, the central control display screen updates the occupant distribution position in response to the input instruction, and thus the number and position information of the in-vehicle occupants is determined. Then, a control instruction for turning on the light can be generated according to the first position in the updated occupant distribution position, and a control instruction for turning off the light can be generated according to the second position in the updated occupant distribution position.

[0104] In an embodiment, updating the occupant distribution position can include converting one or more first positions to second positions, converting one or more second positions to first positions, converting all first positions to second positions at once, and converting all second positions to first positions at once. That is, one or more occupant distribution positions can be added, one or more occupant distribution positions can be deleted, all occupant distribution positions can be turned on, and all occupant distribution positions can be turned off.

[0105] In order to realize the above one-key conversion function, as shown in Figure 4 The central control screen can further include a "synchronization" key. When the "synchronization" key is lighted, all vehicle lights are turned on, and when the "synchronization" key is extinguished, all vehicle lights are turned off.

[0106] In addition, if the check fails, the identification device 210 needs to generate an error code while updating the occupant distribution position to remind the user that the above information identification is incorrect. Among them, the occasional check may be due to complex scenes such as dim light, etc., but if the error code appears many times, it may be that the identification device 210 is malfunctioning and needs to be repaired.

[0107] In addition, after determining and checking the occupant distribution position by the identification device 210, manual intervention can be performed on the determined occupant distribution position. That is, the occupant distribution position determined by the identification device 210 has no error, but the user still needs to make individualized adjustments to the occupant distribution position.

[0108] Therefore, the control system 200 of the present application can also be used to perform the following function steps:

[0109] 1) detecting whether an intervention control instruction is received within a second set time;

[0110] 2) in the case where the intervention control instruction is received within the second set time, updating the occupant distribution position in response to the intervention control instruction and storing the intervention control instruction; and

[0111] 3) generating user preference information according to the stored intervention control instruction, to automatically intervene in the occupant distribution position through the user preference information.

[0112] In an embodiment, the intervention control instruction can include a touch type instruction, a language type instruction, or a gesture type instruction. For example, the occupant distribution position can be first displayed through the in-vehicle central control display screen, and the second set time can be the time for the display screen to display the occupant distribution position, which can also be set according to actual application, for example, 3-15 seconds, which can be preferably set to 5 seconds. In addition, the second set time can be after the first set time, for example, the first set time is 0-5 seconds, and the second set time is 5-10 seconds. In addition, since the fault is a small probability event, the second set time can be longer than the first set time, for example, the first set time is 0-3 seconds, and the second set time is 3-8 seconds.

[0113] In another embodiment, the occupant distribution position can also be broadcast through the in-vehicle voice broadcast device, or lit through the in-vehicle physical button.

[0114] In an embodiment, updating the occupant distribution position can include converting one or more first positions to second positions, converting one or more second positions to first positions, converting all first positions to second positions at one key, and converting all second positions to first positions at one key. That is, one or more occupant distribution positions can be added, one or more occupant distribution positions can be deleted, all occupant distribution positions can be turned on, and all occupant distribution positions can be turned off.

[0115] The above function steps are to intervene in the occupant distribution position determined in the recognition device 210 through the intervention control instruction. If the user intervenes, it indicates that the user has personalized needs for the occupant distribution position. Therefore, the intervention control instruction can be stored, and user preference information can be generated according to the stored intervention control instruction, to automatically intervene in the occupant distribution position through the user preference information. Among them, the accidental intervention can be due to the user's temporary intention, etc., but if the user intervenes multiple times, it can be the user's preference. In order to further improve the user experience, the user preference information can be intelligently generated in a machine learning manner according to the content and frequency of the stored intervention control instruction. In this way, after the occupant distribution position is recognized and checked in the subsequent, the occupant distribution position can be automatically intervened through the user preference information, so that the occupant distribution position can be adjusted to the user's habit mode without user operation, improving the automation and intelligence of the car-machine interaction, and optimizing the user experience.

[0116] The present application has the following advantages without affecting the traditional operation mode:

[0117] 1) The present application provides a scheme for automatically determining the number and position of passengers in the vehicle through image recognition technology, and the number and position of passengers in the vehicle can also be manually manipulated, confirmed and changed through the center display screen;

[0118] 2) The present application provides a vehicle interior area distinguishing display icon and control system, which can realize automatic independent opening or closing of the multi-area atmosphere lamp of the vehicle, increase the sense of technology of the automobile, and be more intelligent;

[0119] 3) The present application can reduce the load of the interior lamp system of the vehicle while ensuring the atmosphere and lighting requirements of the interior atmosphere lamp, save energy consumption, and especially for electric vehicles, save electric energy to increase the driving range;

[0120] 4) The present application can also be used in more number and function atmosphere lamps, and the principle is the same, only the number of areas and corresponding numbers are increased.

[0121] In order to better illustrate the present application, the following examples are used to explain the complete operation process of the present scheme:

[0122] Suppose that during a driving process, only the main driver and the second row area have passengers.

[0123] 1) First, after the driver and the passenger in the rear right area get on the vehicle, the BCM detects the vehicle unlocking operation and sends a signal to activate the interior camera to take a photo.

[0124] 2) After that, the image processing module receives the interior panoramic picture, compares and analyzes it with the standard picture, and sends the passenger position and number information to the atmosphere lamp control module and the BCM. Then, the atmosphere lamp control module and the BCM first send the information to the interior center display screen, and the image as shown in Figure 10 is displayed on the interior center display screen, wherein the gray block represents the selected and opened module, and the white block represents the unselected and closed module. The image is displayed for 5 seconds, and during this period, the system does not detect any instruction input (including verification control instruction and intervention control instruction), indicating that the driver does not operate the display screen to change the area.

[0125] 3) After 5 seconds, the atmosphere lamp control module sends a signal to control the atmosphere lamps 1, 2 and 9 corresponding to the main driver area and the reading lamp 11 to be turned on, and controls the atmosphere lamps 7, 3 and 8 corresponding to the second row area and the reading lamp 12 to be turned on. The atmosphere lamps and reading lamps of other areas are in the closed state.

[0126] Through the above control system and control method, the purpose of opening the atmosphere lamp and the reading lamp according to the passenger position is achieved.
