[0031] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0032] In the description of this application, unless otherwise specified or limited, the term "connection" should be understood in a broad sense. For example, it can mean a fixed connection, a detachable connection, or an integral connection; it can mean a direct connection, an indirect connection through an intermediate medium, or internal communication between two components; it can mean a communication connection; or it can mean an electrical connection. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0033] See also Figure 1 and Figure 2 , Figure 1 A structural block diagram of a vehicle provided in the first embodiment of the present application; Figure 2This is a structural block diagram of the lighting module control system provided in the first embodiment of the present application.

[0034] like Figure 1 As shown, in the first embodiment, the vehicle 1 includes a lighting module control system 10, a vehicle body 20, and a lighting module 30. The vehicle body 20 includes a door 21. The vehicle 1 can be, but is not limited to, a bus, a car, or a truck.

[0035] like Figure 2 As shown, the light module control system 10 is used to control the light module 30 in the vehicle 1 . The light module control system 10 includes a light sensor 100 and a controller 200 . The light sensor 100 and the light module 30 are connected to the controller 200 , respectively.

[0036] The light sensor 100 is used to obtain the ambient light intensity at the current location of the vehicle 1 .

[0037] The controller 200 is used to control the lighting module 30 to enter different working modes according to the different intensities of the ambient light, and further includes:

[0038] The controller 200 is configured to control the lighting module 30 to enter a night mode when the ambient light intensity is less than or equal to a first preset light intensity value.

[0039] The controller 200 is configured to control the lighting module 30 to enter a special mode and obtain a first preset duration value when the ambient light intensity is greater than a first preset light intensity value and less than a second preset light intensity value.

[0040] The controller 200 is configured to control the lighting module 30 to switch from the special mode to the day mode when the ambient light intensity is within a range greater than a first preset light intensity value and less than a second preset light intensity value for a duration greater than or equal to the first preset duration value;

[0041] The controller 200 is configured to control the lighting module 30 to enter a daytime mode when the ambient light intensity is greater than or equal to a second preset light intensity value; wherein the second preset light intensity value is greater than the first preset light intensity value.

[0042] In this embodiment, the controller 200 controls the lighting module 30 to enter different working modes according to the different ambient light intensities. In different working modes, the corresponding lights in the lighting module 30 are controlled to turn on or off and adjusted to a preset brightness, thereby improving driving safety and enhancing user experience in different driving scenarios.

[0043] Specifically, for example: the first preset light intensity value is 5 lux (lux, unit of illumination), the second preset light intensity value is 100 lux, and the first preset duration value is 2 minutes. The values ​​here are only examples and are not limiting.

[0044] The controller 200 is configured to control the lighting module 30 to enter a night mode when the ambient light intensity is less than or equal to 5 lux.

[0045] The controller 200 is configured to control the lighting module 30 to enter a special mode when the ambient light intensity is greater than 5 lux and less than 100 lux, and obtain a first preset duration value of 2 minutes.

[0046] The controller 200 is configured to control the lighting module 30 to switch from the special mode to the day mode when the ambient light intensity is within a range of greater than 5 lux and less than 100 lux for a duration greater than or equal to 2 minutes.

[0047] The controller 200 is configured to control the lighting module 30 to enter the daytime mode when the ambient light intensity is greater than or equal to 100 lux.

[0048] Among them, the driving scenarios for entering the special mode include but are not limited to entering a tunnel during the day, entering an underground garage during the day, and scenarios where the environment suddenly darkens, such as the weather suddenly darkens during the day.

[0049] The driving scenario for entering the daytime mode includes daytime with good weather conditions.

[0050] The driving scenarios for entering the night mode include places without light at night, places with street lights at night, or places with city street lights at night, but the street lights and city street lights are insufficiently illuminated.

[0051] The first preset duration value can be stored in advance in a memory (not shown), such as a cloud platform (for convenient modification of the first preset duration value), and the controller 200 is connected to the memory. Specifically, in one embodiment, the lighting module control system 10 is wirelessly connected to the cloud platform. The value set in the memory can be manually input based on a generally applicable value obtained after a large amount of data training. For example, if the time it takes to pass through a tunnel does not exceed a certain value under normal circumstances, this value can be set as the first preset duration for passing through the tunnel. The first preset duration value can also be a value calculated online. For example, if the weather conditions obtained online during driving indicate that it will rain for 20 minutes, then the first preset duration value is 20 minutes. Therefore, the method for obtaining the first preset duration value can be: the controller 200 reads the first preset duration value stored in the memory. When the memory is a cloud platform, the controller 200 controls a communication module (not shown) to communicate with the cloud platform to obtain the first preset duration value.

[0052] In the present application, the Xth preset number of passengers, the Xth preset interval distance, the Xth preset duration value, the Xth preset continuous lighting duration, the Xth preset lighting brightness and the Xth preset interval distance can be generally applicable values ​​obtained after a large amount of data drills and stored in a memory in advance, or values ​​obtained by network calculation, where X is one, two, three...etc.

[0053] In some embodiments, the lighting module control system 10 includes a plurality of light sensors 100, which are distributed at different positions of the vehicle 1. The specific number can be adjusted according to actual conditions, so as to avoid uneven distribution of ambient light around the vehicle 1, resulting in the acquired ambient light intensity not reflecting the actual conditions. For example, when the vehicle 1 passes by, only the position where the light sensor 100 is located is illuminated by strong light, but at this time the actual ambient light intensity is less than or equal to the first preset light intensity value. Therefore, the environmental conditions of the current position of the vehicle 1 can be further comprehensively identified and judged based on the ambient light intensities acquired by the plurality of light sensors 100.

[0054] In other embodiments, the lighting module control system 10 includes a light sensor 100 that detects the ambient light intensity at the current location of the vehicle 1. The controller 200 controls the lighting module 30 to enter night mode only when the ambient light intensity is less than or equal to a first preset light intensity value and lasts for longer than a preset duration. The controller 200 controls the lighting module 30 to enter special mode only when the ambient light intensity is greater than the first preset light intensity value and less than a second preset light intensity value and lasts for longer than a preset duration. The controller 200 controls the lighting module 30 to switch from special mode to day mode when the ambient light intensity is greater than the first preset light intensity value and less than the second preset light intensity value for a duration greater than or equal to another preset duration, wherein the other preset duration is greater than the first preset duration. The controller 200 controls the lighting module 30 to enter day mode only when the ambient light intensity is greater than or equal to the second preset light intensity value and lasts for longer than a preset duration.

[0055] In this embodiment, since there is only one light sensor 100, the detection and judgment time is increased when detecting the ambient light intensity, thereby avoiding the situation where only the position where the light sensor 100 is located is illuminated by strong light when the vehicle 1 passes by, but the actual ambient light intensity at this time cannot reflect the actual situation and an error occurs.

[0056] See also Figure 3 , Figure 3 This is a structural block diagram of a vehicle provided in the second embodiment of the present application.

[0057] like Figure 3 As shown, the second embodiment is similar to the first embodiment, but the difference is that in the second embodiment, the vehicle 1 further includes a distance measuring device 40, a dimming module 50 and a passenger detector 60, and the passenger detector 60, the distance measuring device 40 and the dimming module 50 are respectively connected to the controller 200. The lighting module 30 includes a door area light 31;

[0058] The controller 200 is used to control the lighting module 30 to enter night mode. When at least one door 21 changes from closed to open, and the passenger detector 60 detects that a passenger moves relative to the vehicle 1, and the distance measuring instrument 40 measures that the distance between the passenger moving relative to the vehicle 1 and the open door 21 is less than a first preset interval distance, the controller 200 controls the door area light 31 to turn on at a first preset lighting brightness, or controls the dimming module 50 and the door area light 31 to turn on at a corresponding lighting brightness according to the number of moving passengers.

[0059] For example: the first preset interval distance is 0.5m (meter), the value is only for example and not limiting. When at least one door 21 changes from closed to open, and the passenger detector 60 detects that a passenger moves relative to the vehicle 1, and the distance measuring instrument 40 measures that the distance between the passenger moving relative to the vehicle 1 and the open door 21 is less than 0.5m, the controller 200 controls the door area light 31 to turn on with the first preset lighting brightness, or controls the dimming module 50 and the door area light 31 according to the number of moving passengers so that the door area light 31 turns on with the corresponding lighting brightness.

[0060] The door area lights 31 include any one or more of: step lights (not marked), passenger door lights (not marked), passenger door lights (not marked), and driver area small lights (not marked).

[0061] It is understandable that the lighting module control system 10 may include the passenger detector 60, the distance measuring device 40 and the dimming module 50, or may not include the passenger detector 60, the distance measuring device 40 and the dimming module 50, or may include only one or two of the passenger detector 60, the distance measuring device 40 and the dimming module 50. Figure 3 The diagram shows a case where the lighting module control system 10 includes the passenger detector 60 , the distance measuring device 40 and the dimming module 50 .

[0062] Among them, the controller 200 is used to control the turning on and off of the door area light 31, and the dimming module 50 is used to adjust the lighting brightness of the door area light 31. The first preset lighting brightness is the default lighting brightness. As long as the door area light 31 is turned on, the brightness of the door area light 31 is the first preset lighting brightness. Therefore, controlling the door area light 31 to turn on with the first preset lighting brightness only requires the controller 200 to control the door area light 31 to turn on, and controlling the door area light 31 to turn on with the corresponding lighting brightness according to the number of moving passengers requires the controller 200 to control the door area light 31 to turn on, and at the same time, the dimming module 50 needs to adjust the lighting brightness of the door area light 31 to the corresponding lighting brightness when turning on.

[0063] In one embodiment, the passenger detector 60 includes an infrared detector, and the distance measuring device 40 includes an optical rangefinder.

[0064] In this embodiment, when passengers get on or off the vehicle, the controller 200 controls the door area lights 31 to illuminate at a first preset brightness, or turns on the door area lights 31 at a corresponding brightness according to the number of moving passengers, thereby reducing the occurrence of passengers falling due to not being able to see the road conditions clearly when getting on or off the vehicle.

[0065] Specifically, when there are only passengers getting on the bus but no passengers getting off, only the boarding door lights, the step lights at the boarding door and the small lights in the driver's area can be turned on; when there are only passengers getting off the bus but no passengers getting on, only the disembarking door lights and the step lights at the disembarking door can be turned on.

[0066] In some embodiments, the passenger detector 60 is also used to count the number of moving passengers. After "the controller 200 controls the door area light 31 to turn on with a first preset lighting brightness", the dimming module 50 adjusts the lighting brightness of the door area light 31 according to the number of moving passengers.

[0067] In this embodiment, the door area lights 31 are immediately turned on at a first preset brightness upon detecting passenger movement, and the dimming module 50 is then controlled to adjust the brightness of the door area lights 31 based on the number of moving passengers. This provides a faster response than turning on the door area lights 31 at a brightness corresponding to the number of moving passengers. Furthermore, the dimming module 50 adjusts the brightness of the door area lights 31 based on the number of moving passengers, thereby ensuring lighting quality while saving energy.

[0068] Specifically, the “adjusting the illumination brightness of the door area light 31 according to the number of the moving passengers” specifically includes:

[0069] When the number of the moving passengers is less than or equal to the first preset number of passengers, the lighting brightness of the door area lights 31 is maintained at the first preset lighting brightness, that is, the dimming module 50 does not adjust the lighting brightness of the door area lights 31 .

[0070] When the number of the moving passengers is greater than the first preset number of passengers and less than or equal to the second preset number of passengers, the dimming module 50 is configured to adjust the illumination brightness of the door area lights 31 to the second preset illumination brightness.

[0071] When the number of the moving passengers is greater than the second preset number of passengers and less than or equal to the third preset number of passengers, the dimming module 50 adjusts the lighting brightness of the door area lights 31 to the third preset lighting brightness.

[0072] When the number of the moving passengers is greater than the third preset number of passengers, the dimming module 50 adjusts the lighting brightness of the door area lights 31 to a fourth preset lighting brightness.

[0073] Among them, the third preset number of passengers is greater than the second preset number of passengers, the second preset number of passengers is greater than the first preset number of passengers, and the first preset number of passengers is greater than 1; the fourth preset lighting brightness is greater than the third preset lighting brightness, the third preset lighting brightness is greater than the second preset lighting brightness, and the second preset lighting brightness is greater than the first preset lighting brightness.

[0074] Specifically, in this embodiment and the following embodiments, the first preset number of passengers can be 2, the second preset number of passengers can be 4, and the third preset number of passengers can be 8. The first preset lighting brightness can be 20% of the maximum brightness of the door area light 31, the second preset lighting brightness can be 40% of the maximum brightness of the door area light 31, the third preset lighting brightness can be 70% of the maximum brightness of the door area light 31, and the fourth preset lighting brightness can be the maximum brightness of the door area light 31. The values ​​here are only for example and are not limiting. They can be adjusted according to actual conditions.

[0075] In some embodiments, the step of “turning on the door area lights 31 at corresponding lighting brightness according to the number of moving passengers” may specifically include:

[0076] When the number of the moving passengers is less than or equal to the first preset number of passengers, the controller 200 and the dimming module 50 turn on the door area lights 31 at the first preset lighting brightness.

[0077] When the number of the moving passengers is greater than a first preset number of passengers and less than or equal to a second preset number of passengers, the controller 200 and the dimming module 50 turn on the door area lights 31 at the second preset lighting brightness.

[0078] When the number of the moving passengers is greater than the second preset number of passengers and less than or equal to the third preset number of passengers, the controller 200 and the dimming module 50 turn on the door area lights 31 at the third preset lighting brightness.

[0079] When the number of the moving passengers is greater than the third preset number of passengers, the controller 200 and the dimming module 50 turn on the door area lights 31 at the fourth preset lighting brightness.

[0080] Among them, the third preset number of passengers is greater than the second preset number of passengers, the second preset number of passengers is greater than the first preset number of passengers, and the first preset number of passengers is greater than 1; the fourth preset lighting brightness is greater than the third preset lighting brightness, the third preset lighting brightness is greater than the second preset lighting brightness, and the second preset lighting brightness is greater than the first preset lighting brightness.

[0081] In some embodiments, after the open door 21 is closed, or when the open door 21 is not closed and the duration of time it is not closed is greater than a first preset duration of time (for example, 3 minutes, the value is only for example and not limiting), the controller 200 is used to control the door area light 31 to be turned off.

[0082] That is, after the passengers have completed getting on and off the vehicle and the door 21 is closed normally, the door area light 31 is turned off to avoid wasting electricity. In another scenario, after the passengers have completed getting on and off the vehicle, but the door 21 malfunctions and the door 21 does not close normally, the door area light 31 is turned off after a period of time to prevent the door 21 from being unable to close and the door area light 31 from continuing to work, resulting in the depletion of power.

[0083] In other embodiments, when the passenger detector 60 does not detect any passenger movement within a preset period of time, the controller 200 is configured to control the door area light 31 to turn off.

[0084] In some embodiments, the lighting module 30 also includes a passenger area light 32; when the controller 200 controls the lighting module 30 to enter night mode, and the passenger detector 60 detects that a passenger is moving in the vehicle 1, the controller 200 controls the passenger area light 32 to turn on with a fifth preset lighting brightness, or controls the dimming module 50 and the passenger area light 32 according to the number of moving passengers so that the passenger area light 32 turns on with a corresponding lighting brightness.

[0085] The passenger area lights 32 include any one or more of ceiling lights (not marked) and interior ambient lights (not marked).

[0086] The fifth preset lighting brightness is a default lighting brightness, that is, when the controller 200 controls the passenger area light 32 to turn on, the lighting brightness of the passenger area light 32 is the fifth preset lighting brightness.

[0087] Specifically, the fifth preset lighting brightness may be 20% of the maximum brightness of the passenger area light 32 , which is only an example and not a limitation.

[0088] In this embodiment, when the passenger detector 60 detects that a passenger is moving in the vehicle 1, the controller 200 controls the passenger area light 32 to turn on at the fifth preset lighting brightness, or controls the dimming module 50 and the passenger area light 32 according to the number of moving passengers so that the passenger area light 32 turns on at the corresponding lighting brightness, ensuring that the lighting brightness meets the lighting requirements while being more energy-efficient and more intelligent.

[0089] In some embodiments, the “turning on the passenger area lights 32 at a corresponding lighting brightness according to the number of moving passengers” specifically includes:

[0090] When the number of the moving passengers is less than or equal to a fourth preset number of passengers, the controller 200 controls the dimming module 50 and the passenger area light 32 to turn on the passenger area light 32 at a sixth preset lighting brightness.

[0091] When the number of the moving passengers is greater than the fourth preset number of passengers and less than or equal to the fifth preset number of passengers, the controller 200 controls the dimming module 50 and the passenger area light 32 to turn on the passenger area light 32 at a seventh preset lighting brightness.

[0092] When the number of moving passengers is greater than the fifth preset number of passengers and less than or equal to the sixth preset number of passengers, the controller 200 controls the dimming module 50 and the passenger area light 32 to turn on the passenger area light 32 at an eighth preset lighting brightness.

[0093] When the number of moving passengers is greater than the sixth preset number of passengers and less than or equal to the seventh preset number of passengers, the controller 200 controls the dimming module 50 and the passenger area light 32 to turn on the passenger area light 32 at a ninth preset lighting brightness.

[0094] Among them, the fourth preset number of passengers is smaller than the fifth preset number of passengers, and the fifth preset number of passengers is smaller than the sixth preset number of passengers; the sixth preset lighting brightness is smaller than the seventh preset lighting brightness, the seventh preset lighting brightness is smaller than the eighth preset lighting brightness, and the eighth preset lighting brightness is smaller than the ninth preset lighting brightness, and the sixth preset lighting brightness may also be the default lighting brightness.

[0095] Specifically, in this embodiment and some of the following embodiments, the fourth preset number of passengers can be 1, the fifth preset number of passengers can be 4, the sixth preset number of passengers can be 10, the sixth preset lighting brightness can be 20% of the maximum brightness of the passenger area light 32, the seventh preset lighting brightness can be 40% of the maximum brightness of the passenger area light 32, the eighth preset lighting brightness can be 70% of the maximum brightness of the passenger area light 32, and the ninth preset lighting brightness can be the maximum brightness of the passenger area light 32. The values ​​here are only examples and are not limiting.

[0096] In this embodiment, the number of moving passengers is compared with the fourth preset number of passengers, the fifth preset number of passengers, and the sixth preset number of passengers and the seventh preset number of passengers, thereby determining the brightness of the passenger area light 32 when it is turned on. It will be appreciated that in other embodiments, the seventh preset number of passengers, the eighth preset number of passengers, and so on may also be compared with the number of moving passengers, or only one or two of the fourth preset number of passengers, the fifth preset number of passengers, and the sixth preset number of passengers may be compared with the number of moving passengers. The controller 200 then controls the dimming module 50 and the passenger area light 32 to turn on the passenger area light 32 at the preset brightness.

[0097] In some embodiments, when the controller 200 controls the lighting module 30 to enter night mode, and the passenger detector 60 detects that a passenger is moving in the vehicle 1, the controller 200 controls the dimming module 50 and the passenger area light 32 so that the passenger area light 32 is turned on at the fifth preset lighting brightness. After the passenger area light 32 is turned on at the fifth preset lighting brightness, the lighting brightness of the passenger area light 32 is adjusted according to the number of moving passengers detected by the passenger detector 60.

[0098] The control method in this embodiment has a faster response speed because it is not necessary to determine the number of moving passengers before turning on the passenger area lights 32.

[0099] In some embodiments, after the continuous lighting duration of the passenger area light 32 at different lighting brightness reaches a preset continuous lighting duration, the dimming module 50 is used to adjust the lighting brightness of the passenger area light 32 or turn off the passenger area light 32.

[0100] Specifically, when the passenger area light 32 is continuously illuminated at the fifth preset illumination brightness for a duration greater than the first preset continuous illumination duration, the controller 200 controls the passenger area light 32 to be turned off.

[0101] When the passenger area light 32 is continuously illuminated at the seventh preset lighting brightness for a period longer than the second preset continuous lighting period, the dimming module 50 is used to adjust the lighting brightness of the passenger area light 32 to the sixth preset lighting brightness, or the controller 200 is used to control the passenger area light 32 to be turned off.

[0102] When the passenger area light 32 is continuously illuminated at the eighth preset lighting brightness for a period longer than the third preset continuous lighting period, the dimming module 50 is used to adjust the lighting brightness of the passenger area light 32 to the seventh preset lighting brightness, or the controller 200 is used to control the passenger area light 32 to be turned off.

[0103] When the passenger area light 32 is continuously illuminated at the ninth preset lighting brightness for a period longer than the fourth preset continuous lighting period, the dimming module 50 is used to adjust the lighting brightness of the passenger area light 32 to the eighth preset lighting brightness, or the controller 200 is used to control the passenger area light 32 to be turned off.

[0104] Specifically, the first preset continuous lighting duration, the second preset continuous lighting duration, the third preset continuous lighting duration and the fourth preset continuous lighting duration are the same, which is 5 minutes. The values ​​are only for example and are not limiting.

[0105] In some other embodiments, at least one of the first preset continuous lighting duration, the second preset continuous lighting duration, the third preset continuous lighting duration, and the fourth preset continuous lighting duration is different from the others. For example, the first preset continuous lighting duration is 1 minute, the second preset continuous lighting duration is 2 minutes, the third preset continuous lighting duration is 4 minutes, and the fourth preset continuous lighting duration is 5 minutes.

[0106] In this embodiment, when the passenger area light 32 has been continuously illuminated at a predetermined brightness for a predetermined duration, the dimming module 50 is configured to gradually reduce the brightness of the passenger area light 32, allowing the passenger's eyes to adjust to the light and providing a more comfortable experience. The controller 200 also directly turns off the passenger area light 32, which is more energy-efficient.

[0107] In some embodiments, the lighting module 30 includes a door area light 31 and a passenger area light 32; when the controller 200 controls the lighting module 30 to enter a special mode, and the passenger detector 60 detects that the number of passengers in the vehicle 1 is greater than the seventh preset number of passengers, the controller 200 is used to control the door area light 31 and / or the passenger area light 32 to turn on.

[0108] The seventh preset number of passengers may be zero or any other positive integer.

[0109] The door area light 31 may be turned on at a tenth preset lighting brightness, and / or the passenger area light 32 may be turned on at an eleventh preset lighting brightness, and the tenth preset lighting brightness may be different from the eleventh preset lighting brightness.

[0110] Among them, the tenth preset lighting brightness can be 50% of the maximum brightness of the door area light 31, and the eleventh preset lighting brightness can be 50% of the maximum brightness of the passenger area light 32. The values ​​are only for example and are not limited. The maximum brightness of the door area light 31 and the maximum brightness of the passenger area light 32 can be the same or different.

[0111] In this embodiment, in a special mode (such as when entering a tunnel during the day), the passenger detector 60 detects that the number of passengers in the vehicle 1 is greater than the seventh preset passenger number (for example, the number of passengers in the vehicle 1 is greater than zero, that is, the seventh preset passenger number is zero), and the controller 200 controls the door area lights 31 and / or the passenger area lights 32 to turn on. At this time, turning on the door area lights 31 and / or the passenger area lights 32 can reduce the stimulation to the human eyes caused by the sudden dimming of light.

[0112] Specifically, in one embodiment, when the controller 200 controls the lighting module 30 to enter a special mode and the passenger detector 60 detects that the number of passengers in the vehicle 1 is greater than a seventh preset number of passengers, the controller 200 is used to control the passenger area light 32 to turn on.

[0113] In this embodiment, the stimulation to the human eye caused by the sudden dimming of light can be reduced in special driving scenarios such as entering a tunnel during the day, and compared with turning on both the door area light 31 and the passenger area light 32 , more power can be saved.

[0114] Furthermore, when the continuous lighting time of the door area light 31 and / or the passenger area light 32 is greater than the fifth preset continuous lighting time (for example, 2 minutes, the value is only for example and not limiting), the dimming module 50 lowers the lighting brightness of the door area light 31 and / or the passenger area light 32, or the controller 200 controls the door area light and / or the passenger area light 32 to turn off.

[0115] For example, the fifth preset continuous lighting duration is the duration of passing through a tunnel. After passing through the tunnel, the dimming module 50 lowers the brightness of the door area lights 31 and / or the passenger area lights 32, or the controller 200 controls the door area lights 31 and / or the passenger area lights 32 to turn off to avoid wasting electricity.

[0116] In some embodiments, the lighting module 30 includes a door area light 31; when the controller 200 controls the lighting module 30 to enter the daytime mode, and at least one door 21 changes from closed to open, and at the same time the passenger detector 60 detects that a passenger moves relative to the vehicle 1, and the distance measuring instrument 40 measures that the distance between the passenger and the open door 21 is less than a second interval distance (for example, 0.5m, the value is only for example and not limited), the controller 200 controls the door area light 31 to turn on.

[0117] Among them, the controller 200 can also control the dimming module 50 and the door area light 31 so that the door area light 31 is turned on at a twelfth preset lighting brightness (for example, 50% of the maximum brightness of the door area light 31, the value is only an example and is not limited).

[0118] Among them, the door area light 31 can be installed at the edge of the step or the edge of the door of the vehicle 1 to help passengers distinguish different steps, or remind passengers to pay attention to the footsteps, thereby improving the safety of passengers getting on and off the vehicle.

[0119] Furthermore, when the door area light 31 is continuously illuminated at the twelfth preset lighting brightness for a duration greater than the seventh preset continuous lighting duration (for example, 3 minutes, the value is only for example and not limiting), the dimming module 50 lowers the lighting brightness of the door area light 31, or the controller 200 controls the door area light 31 to turn off.

[0120] For example, the seventh preset continuous lighting duration is the duration it takes for passengers to complete getting on and off the vehicle. When the passengers complete getting on and off the vehicle, the dimming module 50 lowers the brightness of the door area light 31, or the controller 200 controls the door area light 31 to turn off, which can avoid wasting electricity.

[0121] See also Figure 4 , Figure 4 A flowchart of a lighting control method provided in one embodiment of the present application.

[0122] like Figure 4 As shown, the lighting control method is applied to the above-mentioned vehicle lighting module control system, and the method includes:

[0123] Step S1: Obtaining the ambient light intensity at the current location of the vehicle.

[0124] The lighting module is controlled to enter different working modes according to the intensity of the ambient light, including:

[0125] Step S2: Determine whether the ambient light intensity is less than or equal to a first preset light intensity value. If yes, execute step S3: control the lighting module to enter night mode.

[0126] If not, executing step S4: determining whether the ambient light intensity is less than a second preset light intensity value; if not, executing step S5: controlling the lighting module to enter daytime mode.

[0127] If yes, then execute step S6: control the lighting module to enter special mode and obtain a first preset duration value. Step S7: determine whether the duration of the ambient light intensity being greater than the first preset light intensity value and less than the second preset light intensity value is less than the first preset duration value. If yes, execute step S6. If not, execute step S5: control the lighting module to enter daytime mode.

[0128] Wherein, the second preset light intensity value is greater than the first preset light intensity value.

[0129] In this embodiment, the lighting module is controlled to enter different working modes according to the different intensities of the ambient light. In different working modes, the corresponding lights are controlled to be turned on or off, and / or the brightness of the corresponding lights is adjusted, thereby improving driving safety and enhancing user experience in different driving scenarios.

[0130] Furthermore, after step S6: determining whether the duration is less than a first preset duration value, the method further includes: if not, executing step S5: controlling the lighting module to enter daytime mode.

[0131] See also Figure 5 , Figure 5 A schematic diagram of the control flow of the door area lights in night mode provided in one embodiment of the present application.

[0132] In some embodiments, the lighting module includes a door area light; in step S3: after controlling the lighting module to enter the night mode, Figure 5 As shown, the method further includes:

[0133] Step S31: Determine whether any door is open.

[0134] If a door is opened, step S32 is executed: determining whether a passenger moves relative to the vehicle; if no door is opened, continuing to detect whether a door is opened.

[0135] If a passenger moves relative to the vehicle, step S33 is executed: determining whether the distance between the passenger and the open door is less than a first preset distance. If no passenger moves relative to the vehicle, the process continues to detect whether a door is opened (e.g., Figure 5 as shown), or continue to detect whether there is a passenger moving relative to the vehicle.

[0136] If the distance between the passenger and the open door is less than the first preset distance, then step S34 is executed: the door area lights are controlled to be turned on at the first preset brightness, or the door area lights are controlled to be turned on at corresponding brightness according to the number of moving passengers. If the distance between the passenger and the open door is greater than or equal to the first preset distance, then the detection of whether a door is opened (e.g. Figure 5 as shown), or continue to detect whether there is a passenger moving relative to the vehicle.

[0137] The door area lights include any one or more of step lights, passenger door lights, passenger door lights and driver area small lights.

[0138] In this embodiment, when passengers get on or off the vehicle, the door area lights are controlled to illuminate at a first preset brightness, or the door area lights are turned on at a corresponding brightness according to the number of moving passengers, thereby reducing the occurrence of passengers falling due to not being able to see the road conditions clearly when getting on or off the vehicle.

[0139] Furthermore, the method further comprises:

[0140] Step S35: Determine whether the opened door is closed. If the opened door is closed, execute step S37: Control the door area light to be turned off.

[0141] If the opened door is not closed, step S36 is executed: determining whether the duration of the door not being closed is greater than a first preset duration of the door not being closed.

[0142] If the duration of the door opening is greater than the first preset duration, step S37 is executed: the door area light is turned off. If the duration of the door opening is less than or equal to the first preset duration, the duration of the door opening is accumulated and a determination is made as to whether the accumulated duration is greater than the first preset duration.

[0143] That is, after the passengers have completed getting on and off the bus and the doors are closed normally, the door area lights are controlled to be turned off to avoid wasting electricity. In another scenario, after the passengers have completed getting on and off the bus, but the doors malfunction and the doors do not close normally, after a period of time, the door area lights are controlled to be turned off to prevent the doors from being unable to close and the door area lights from continuing to work, resulting in power depletion.

[0144] In some embodiments, after “turning on the door area lights at the first preset illumination level”, the method further includes:

[0145] The lighting brightness of the door area lights is adjusted according to the number of moving passengers.

[0146] In this embodiment, the brightness of the door area lights is adjusted based on the number of passengers moving, thereby ensuring effective lighting while saving energy. For example, the duration of passengers getting on and off the vehicle is the first preset continuous lighting duration. After passengers get on and off the vehicle, the door area lights are controlled to stop lighting, thus saving energy.

[0147] See also Figure 6 , Figure 6 A schematic diagram of a process for adjusting the illumination brightness of the door area lights in night mode provided in an embodiment of the present application.

[0148] In some embodiments, the step of “adjusting the brightness of the door area lights according to the number of the moving passengers” specifically includes:

[0149] like Figure 6 As shown, step S341: determine whether the number of the moving passengers is less than or equal to the first preset number of passengers. If so, execute step S342: maintain the lighting brightness of the door area lights at the first preset lighting brightness.

[0150] If not, execute step S343: determine whether the number of the moving passengers is less than or equal to the second preset number of passengers; if yes, execute step S344: adjust the lighting brightness of the door area lights to the second preset lighting brightness.

[0151] If not, execute step S345: determine whether the number of the moving passengers is less than or equal to the third preset number of passengers; if yes, execute step S346: adjust the lighting brightness of the door area lights to the third preset lighting brightness.

[0152] If not, execute step S347: adjust the lighting brightness of the door area light to a fourth preset lighting brightness.

[0153] Among them, the third preset number of passengers is greater than the second preset number of passengers, the second preset number of passengers is greater than the first preset number of passengers, and the first preset number of passengers is greater than 1; the fourth preset lighting brightness is greater than the third preset lighting brightness, the third preset lighting brightness is greater than the second preset lighting brightness, and the second preset lighting brightness is greater than the first preset lighting brightness.

[0154] In this embodiment, the number of the moving passengers is compared with the first preset number of passengers, the second preset number of passengers and the third preset number of passengers, and the door area lights are adjusted to the corresponding lighting brightness based on the comparison results. It can be understood that in some other embodiments, more or fewer preset numbers of passengers can be set according to actual conditions for comparison with the number of the moving passengers, and then the door area lights are adjusted to the corresponding lighting brightness.

[0155] See also Figure 7 , Figure 7 A schematic diagram of the control flow of the night mode passenger area lights provided in one embodiment of the present application.

[0156] In some embodiments, the lighting module further includes a passenger area light. After step S3: controlling the lighting module to enter night mode, the method further includes:

[0157] like Figure 7 As shown, step S39: determining whether a passenger has moved in the vehicle. If a passenger has moved in the vehicle, step S40 is executed: controlling the passenger area light to be turned on at a fifth preset brightness, or controlling the passenger area light to be turned on at a corresponding brightness based on the number of passengers moving in the vehicle. If no passenger has moved in the vehicle, the detection of whether a passenger has moved in the vehicle continues.

[0158] The passenger area lights include any one or more of ceiling lights and interior ambient lights.

[0159] In this embodiment, when there are passengers moving in the vehicle, the passenger area lights are turned on with corresponding lighting brightness according to the number of passengers, ensuring that the lighting brightness meets the lighting requirements while being more energy-efficient and more intelligent.

[0160] In some embodiments, the step S40 of “turning on the passenger area lights at corresponding lighting brightness according to the number of moving passengers” specifically includes:

[0161] Step S401: Determine whether the number of moving passengers is less than or equal to a fourth preset number of passengers. If the number of moving passengers is less than or equal to the fourth preset number of passengers, execute step S402: control the passenger area lights to turn on at a sixth preset lighting brightness.

[0162] If the number of moving passengers is greater than the fourth preset number of passengers, step S403 is executed: whether the number of moving passengers is less than or equal to the fifth preset number of passengers is determined; if the number of moving passengers is less than or equal to the fifth preset number of passengers, step S404 is executed: the passenger area lights are controlled to turn on at the seventh preset lighting brightness.

[0163] If the number of moving passengers is greater than the fifth preset number of passengers, step S405 is executed: whether the number of moving passengers is less than or equal to the sixth preset number of passengers is determined; if the number of moving passengers is less than or equal to the sixth preset number of passengers, step S406 is executed: the passenger area lights are controlled to turn on at the eighth preset lighting brightness.

[0164] If the number of the moving passengers is greater than the sixth preset number of passengers, step S407 is executed: the passenger area lights are controlled to turn on at a ninth preset lighting brightness.

[0165] Among them, the fourth preset number of passengers is smaller than the fifth preset number of passengers, and the fifth preset number of passengers is smaller than the sixth preset number of passengers; the sixth preset lighting brightness is smaller than the seventh preset lighting brightness, the seventh preset lighting brightness is smaller than the eighth preset lighting brightness, and the eighth preset lighting brightness is smaller than the ninth preset lighting brightness.

[0166] In this embodiment, the number of moving passengers is compared with the fourth preset number of passengers, and the fifth preset number of passengers is compared with the sixth preset number of passengers, thereby determining the brightness of the passenger area lights when they are turned on. It will be appreciated that in other embodiments, a greater or fewer preset number of passengers may be set for comparison with the number of moving passengers, and then the passenger area lights may be controlled to turn on at the corresponding preset brightness.

[0167] See also Figure 8 , Figure 8 A schematic diagram of a process for adjusting the illumination brightness of the passenger area lights in night mode provided in one embodiment of the present application.

[0168] In some embodiments, the method further comprises:

[0169] After the continuous lighting duration of the passenger area light at different lighting brightness reaches a preset continuous lighting duration, the lighting brightness of the passenger area light is adjusted, or the passenger area light is turned off.

[0170] Specifically, if Figure 8 As shown, the method includes step S71: determining whether the continuous illumination time of the passenger area light at the sixth preset illumination brightness is greater than the first preset continuous illumination time. If the continuous illumination time of the passenger area light at the sixth preset illumination brightness is greater than the first preset continuous illumination time, step S72: turning off the passenger area light. If the continuous illumination time of the passenger area light at the sixth preset illumination brightness is less than or equal to the first preset continuous illumination time, the continuous illumination time of the passenger area light at the sixth preset illumination brightness is further accumulated and determined whether the accumulated time is greater than the first preset continuous illumination time.

[0171] Step S73: Determine whether the duration of the passenger area light's continuous illumination at the seventh preset illumination brightness is greater than the second preset continuous illumination duration. If the duration of the passenger area light's continuous illumination at the seventh preset illumination brightness is greater than the second preset continuous illumination duration, execute Step S74: Adjust the passenger area light's illumination brightness to the sixth preset illumination brightness or turn off the passenger area light. If the duration of the passenger area light's continuous illumination at the seventh preset illumination brightness is less than or equal to the second preset continuous illumination duration, continue to accumulate the duration of the passenger area light's continuous illumination at the seventh preset illumination brightness and determine whether the accumulated duration is greater than the second preset continuous illumination duration.

[0172] Step S75: Determine whether the duration of the passenger area light's continuous illumination at the eighth preset illumination brightness is greater than the third preset continuous illumination duration. If the duration of the passenger area light's continuous illumination at the eighth preset illumination brightness is greater than the third preset continuous illumination duration, execute Step S76: Adjust the passenger area light's illumination brightness to the seventh preset illumination brightness or turn off the passenger area light. If the duration of the passenger area light's continuous illumination at the eighth preset illumination brightness is less than or equal to the third preset continuous illumination duration, continue accumulating the duration of the passenger area light's continuous illumination at the eighth preset illumination brightness and determine whether the accumulated duration is greater than the third preset continuous illumination duration.

[0173] Step S77: Determine whether the duration of the passenger area light's continuous illumination at the ninth preset illumination brightness is greater than the fourth preset continuous illumination duration. If the duration of the passenger area light's continuous illumination at the ninth preset illumination brightness is greater than the fourth preset continuous illumination duration, execute Step S78: Adjust the passenger area light's illumination brightness to the eighth preset illumination brightness or turn off the passenger area light. If the duration of the passenger area light's continuous illumination at the ninth preset illumination brightness is less than or equal to the fourth preset continuous illumination duration, continue accumulating the duration of the passenger area light's continuous illumination at the ninth preset illumination brightness and determine whether the accumulated duration is greater than the fourth preset continuous illumination duration.

[0174] In one embodiment, at least one of the first preset continuous lighting duration, the second preset continuous lighting duration, the third preset continuous lighting duration, and the fourth preset continuous lighting duration is different from the other durations.

[0175] In another embodiment, the first preset continuous lighting duration, the second preset continuous lighting duration, the third preset continuous lighting duration and the fourth preset continuous lighting duration are the same.

[0176] In this embodiment, when the passenger area lights have been continuously illuminated at a preset brightness for a predetermined duration, the brightness of the passenger area lights is gradually reduced, allowing passengers' eyes to adjust to the light and providing a more comfortable experience. Directly shutting off the door area lights is also more energy-efficient.

[0177] See also Figure 9 , Figure 9 This is a schematic diagram of the control flow of the special mode door area lights and passenger area lights provided in one embodiment of the present application.

[0178] In some embodiments, the lighting module includes a door area light and a passenger area light. After step S7: controlling the lighting module to enter a special mode, the method further includes:

[0179] like Figure 9 As shown, step S81: determining whether the number of passengers in the vehicle is greater than a seventh preset number of passengers. If the number of passengers in the vehicle is greater than the seventh preset number of passengers, step S82 is executed: controlling the door area lights and / or the passenger area lights to turn on. If the number of passengers in the vehicle is less than or equal to the seventh preset number of passengers, the number of passengers in the vehicle is further detected to determine whether it is greater than the seventh preset number of passengers.

[0180] In this embodiment, in a special mode (such as when entering a tunnel during the day), the number of passengers in the vehicle is greater than the seventh preset number of passengers (for example, the number of passengers in the vehicle is greater than zero), and the door area lights and / or the passenger area lights are controlled to turn on. At this time, turning on the door area lights and / or the passenger area lights can reduce the irritation to the human eyes caused by the sudden dimming of light.

[0181] Furthermore, the method further comprises:

[0182] Step S83: Determine whether the continuous illumination duration of the door area light and / or the passenger area light is greater than a fifth preset continuous illumination duration. If the continuous illumination duration of the door area light and / or the passenger area light is greater than the fifth preset continuous illumination duration, execute step S84: reduce the illumination brightness of the door area light and / or the passenger area light, or control the door area light and / or the passenger area light to be turned off. If the continuous illumination duration of the door area light and / or the passenger area light is less than or equal to the fifth preset continuous illumination duration, continue to accumulate the continuous illumination duration of the door area light and / or the passenger area light and determine whether it is greater than the fifth preset continuous illumination duration.

[0183] For example, the fifth preset continuous lighting duration is the duration of passing through a tunnel. After passing through the tunnel, the brightness of the door area lights and / or the passenger area lights is lowered, or the door area lights and / or the passenger area lights are turned off to avoid wasting electricity.

[0184] See also Figure 10 , Figure 10 This is a schematic diagram of the control flow of the daytime mode door area lights provided by an embodiment of the present application.

[0185] like Figure 10 As shown, in some embodiments, the lighting module includes a door area light; after step S5: controlling the lighting module to enter the daytime mode, the method further includes:

[0186] Step S51: Determine whether at least one door has changed from closed to open. If at least one door has changed from closed to open, proceed to step S52: Detect whether a passenger has moved relative to the vehicle. If no door has changed from closed to open, continue detecting whether at least one door has changed from closed to open.

[0187] If a passenger moves relative to the vehicle, step S53 is executed: determining whether the distance between the passenger and the open door is less than a second spacing distance; if no passenger moves relative to the vehicle, continuing to detect whether a passenger moves relative to the vehicle; or continuing to detect whether at least one door changes from closed to open.

[0188] If the distance between the passenger and the open door is less than the second distance, step S54 is executed: the door area light is turned on. If the distance between the passenger and the open door is greater than or equal to the second distance, the distance between the passenger and the open door is further detected to determine whether it is less than the second distance; or the detection of whether the passenger moves relative to the vehicle is further detected; or the detection of whether at least one door has opened from closed to open is further detected.

[0189] Among them, the door area lights can be installed at the edge of the steps or the edge of the door of the vehicle to help passengers distinguish different steps, or remind passengers to pay attention to their feet, thereby improving the safety of passengers getting on and off the vehicle.

[0190] Furthermore, the method further comprises:

[0191] Step S55: Determine whether the continuous illumination time of the door area light at the twelfth preset illumination brightness is greater than the seventh preset continuous illumination time. If the continuous illumination time of the door area light at the twelfth preset illumination brightness is greater than the seventh preset continuous illumination time, execute step S56: reduce the illumination brightness of the door area light or control the door area light to be turned off. If the continuous illumination time of the door area light at the twelfth preset illumination brightness is less than or equal to the seventh preset continuous illumination time, continue to accumulate the continuous illumination time of the door area light at the twelfth preset illumination brightness and determine whether the accumulated time is greater than the seventh preset continuous illumination time.

[0192] For example, the seventh preset continuous lighting duration is the duration for passengers to complete getting on and off the bus. When the passengers complete getting on and off the bus, the brightness of the door area lights is lowered or turned off to avoid wasting electricity.
