[0032] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0033] At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the accompanying drawings are not drawn according to actual scale.

[0034] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0035] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0036] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0038] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0039] In related technologies, there are two main approaches to lighting control: manual and automatic. Manual lighting control utilizes electronic switches, virtual switches, and voice control, requiring human intervention and thus lacking sufficient intelligence. Automatic lighting control relies on a single photosensor, but uneven light distribution and external light interference result in inaccurate light intensity signals, failing to accurately reflect ambient light and leading to a high probability of misjudgment and a poor user experience. Furthermore, automatic lighting control using a single image sensor or GPS positioning system also suffers from inaccurate control and a poor user experience.

[0040] In view of this, this disclosure proposes a vehicle lighting control method, device, and vehicle, which improves the operability of lighting control and meets the lighting control needs in more scenarios by combining manual lighting control and automatic lighting control. At the same time, by combining an image sensor with a positioning system for automatic lighting control, and prioritizing the use of the image sensor for vehicle lighting control, the accuracy, effectiveness, and practicality of lighting control are improved.

[0041] Figure 1 This is a schematic flowchart illustrating a vehicle lighting control method according to some embodiments of the present disclosure. Figure 1 As shown, the vehicle lighting control method includes steps S110 to S140.

[0042] In step S110, the current lighting control mode of the vehicle is obtained.

[0043] In some embodiments, the vehicle lighting control method is performed by a vehicle lighting control device.

[0044] In some embodiments, the vehicle's lighting control modes include an automatic mode and a manual mode.

[0045] In some embodiments, the vehicle lighting control device queries the storage module to obtain the characteristic parameters of the vehicle's current lighting control mode. For example, when the characteristic parameter of the current lighting control mode is a first value, it indicates that the vehicle's lighting control mode is automatic; when the characteristic parameter of the current lighting control mode is a second value, it indicates that the vehicle's lighting control mode is manual.

[0046] In step S120, if the vehicle's current lighting control mode is automatic, it is determined whether the image sensor is faulty.

[0047] In some embodiments, the presence or absence of a fault in the image sensor is determined by: determining whether the power supply state and signal transmission state of the image sensor are normal; if both the power supply state and signal transmission state of the image sensor are normal, the image sensor is determined to be fault-free; otherwise, the image sensor is determined to be faulty.

[0048] In some examples, the image sensor includes multiple cameras. In these examples, the presence of a fault in the image sensor is determined as follows: the power supply and signal transmission status of at least N cameras are determined to be normal; if the power supply and signal transmission status of at least N cameras are normal, the image sensor is determined to be fault-free; otherwise, the image sensor is determined to be faulty. Here, N is an integer greater than or equal to 1. For example, let N be an integer greater than 1 and less than the total number of cameras.

[0049] In some examples, the vehicle lighting control unit obtains indication information on the power supply status and signal transmission status of multiple cameras from multiple cameras, and determines whether the power supply status and signal transmission status of the multiple cameras are normal based on the obtained indication information.

[0050] In this embodiment, detecting the power supply and signal transmission status of the image sensor helps to accurately determine whether the image sensor is faulty, thereby improving the reliability of vehicle lighting control based on image detection results. Furthermore, when the image sensor includes multiple cameras, if the power supply and signal transmission status of at least N cameras are normal, and N is an integer greater than 1 and less than the total number of cameras, it is determined that the image sensor as a whole is not faulty. This not only satisfies the requirement that vehicle lighting control can be performed based on image detection results even when some cameras are faulty, improving the operability and applicability of the vehicle lighting control method, but also further improves the accuracy and reliability of vehicle lighting control based on image detection results by performing vehicle lighting control based on images acquired by multiple fault-free cameras.

[0051] In some embodiments, the presence or absence of an image sensor fault is determined as follows: the power supply and signal transmission states of the image sensor are determined to be normal; if both are normal, the image sensor is determined to be occluded and to have a degree of contamination exceeding a contamination threshold; if the image sensor is not occluded and its contamination level is less than the contamination threshold, the image sensor is determined to be fault-free; otherwise, the image sensor is determined to be faulty.

[0052] In some examples, the image sensor includes multiple cameras. In these examples, the presence of a fault in the image sensor is determined as follows: The power supply and signal transmission status of at least N cameras are determined to be normal; if the power supply and signal transmission status of at least N cameras are normal, it is determined whether all at least N cameras are unobstructed and whether the degree of soiling of at least N cameras is less than a soiling threshold; if all at least N cameras are unobstructed and the degree of soiling of at least N cameras is less than the soiling threshold, the image sensor is determined to be fault-free; otherwise, the image sensor is determined to be faulty. Here, N is an integer greater than or equal to 1. For example, let N be an integer greater than 1 and less than the total number of cameras.

[0053] In some examples, the vehicle lighting control unit acquires images from multiple cameras, processes the images using image processing techniques, and determines whether the image is obstructed based on the processing results. Similarly, image processing techniques can be used to process images and determine the degree of camera smudges based on the processing results, and then determine whether the degree of smudges exceeds a smudges threshold.

[0054] In this embodiment of the disclosure, when determining whether an image sensor is faulty, not only the power supply status and signal transmission status of the image sensor are considered, but also whether the image sensor is obstructed and the degree of dirt on the image sensor. This helps to improve the comprehensiveness and accuracy of image sensor fault detection, and thus helps to improve the reliability of vehicle lighting control based on image detection results.

[0055] If the image sensor is not faulty, proceed to step S130; if the image sensor is faulty, proceed to step S140.

[0056] In step S130, the vehicle's lighting system is controlled based on the images acquired by the image sensor.

[0057] In some embodiments, the image sensor includes multiple cameras, and step S130 includes: determining the ambient light intensity (or ambient light brightness) corresponding to each camera based on the image captured by each of the multiple cameras; and controlling the vehicle's lighting system to turn on when the ambient light intensity corresponding to at least M cameras is less than a first light intensity threshold. Here, M is an integer greater than or equal to 2.

[0058] For example, the image sensor includes four cameras, which are respectively positioned at the front, rear, left, and right sides of the excavator. By processing the images captured by these four cameras, the ambient light intensity corresponding to each camera is determined. If the ambient light intensity corresponding to at least two cameras is less than a first light intensity threshold, the vehicle's lighting system is activated; otherwise, the control process ends.

[0059] In this embodiment, vehicle lighting control is performed based on images captured by multiple cameras. Compared to vehicle lighting control based on a single camera, this helps reduce detection blind spots caused by factors such as camera obstruction, thus improving the practicality of the vehicle lighting control method. Furthermore, by controlling the vehicle lighting system to turn on only when the ambient light intensity corresponding to at least M cameras is less than a first light intensity threshold, the accuracy and reliability of vehicle lighting control are improved.

[0060] In other embodiments, the image sensor includes multiple cameras, and the vehicle's lighting system includes multiple light groups. Step S130 includes: determining the ambient light intensity corresponding to each camera based on the image captured by each of the multiple cameras; controlling N1 light groups in the vehicle's lighting system to turn on when the ambient light intensity corresponding to at least M cameras is greater than or equal to a second light intensity threshold and less than a first light intensity threshold; and controlling N2 light groups in the vehicle's lighting system to turn on when the ambient light intensity corresponding to at least M cameras is less than the second light intensity threshold, wherein N2 and N1 are both integers, and N2 is greater than N1.

[0061] In this embodiment of the disclosure, by performing multi-level vehicle lighting control based on the ambient light intensity corresponding to multiple cameras, it is possible to reduce vehicle lighting energy consumption while meeting vehicle lighting requirements.

[0062] In step S140, the vehicle's lighting system is controlled based on the vehicle location information collected by the positioning system and the current time information.

[0063] In some embodiments, the vehicle location information collected by the positioning system includes the vehicle's latitude and longitude information, and the positioning system includes a GPS positioning system or a BeiDou positioning system, etc.

[0064] In some embodiments, step S140 includes: querying the first standard lighting time corresponding to the current vehicle location based on the vehicle location information collected by the positioning system; determining the second standard lighting time corresponding to the current vehicle location based on the first standard lighting time corresponding to the current vehicle location and the set lighting time offset; and controlling the vehicle's lighting system to turn on if the current time is not earlier than the second standard lighting time corresponding to the current vehicle location.

[0065] In some embodiments, step S140 includes: determining the current ambient light intensity based on vehicle location information collected by the positioning system, current time information, and current weather information; outputting a prompt message to turn on the lighting system when the current ambient light intensity is less than a third light intensity threshold; and controlling the vehicle's lighting system to turn on after receiving a confirmation command corresponding to the prompt message. Furthermore, in some embodiments, the vehicle lighting control method further includes: ending the current control process when the current ambient light intensity is greater than or equal to the third light intensity threshold.

[0066] For example, based on the vehicle's latitude and longitude information collected by the positioning system, a table showing the relationship between latitude and longitude and sunset time is consulted to determine the sunset time corresponding to the vehicle's current location; the current time information and current weather information are obtained; based on the difference between the current time and the sunset time corresponding to the vehicle's current location, an initial value of ambient light intensity is determined; based on the current weather information, the initial value of ambient light intensity is corrected, and the corrected ambient light intensity is used as the current ambient light intensity. Then, the current ambient light intensity is compared with a third light intensity threshold, and lighting control is performed based on the comparison result.

[0067] In other embodiments, when determining the current ambient light intensity, in addition to considering the vehicle location information collected by the positioning system, the current time information, and the current weather information, factors such as external lighting information (e.g., lighting information of other vehicles) are also considered.

[0068] In this embodiment, not only vehicle location information and current time information collected by the positioning system are considered, but also current weather information, which helps to improve the accuracy and reliability of vehicle lighting control based on the positioning system. At the same time, by outputting a prompt message to turn on the lighting system when the positioning system determines that it needs to be turned on, and only turning on the lighting system after the user confirms the activation, erroneous operations caused by inaccurate detection results from the positioning system can be reduced, improving the effectiveness of vehicle lighting control and reducing energy consumption.

[0069] In this embodiment, by combining manual and automatic lighting control, the operability of lighting control is improved, meeting the lighting control needs in more scenarios. Simultaneously, by combining an image sensor with a positioning system for automatic lighting control, and prioritizing the use of the image sensor for vehicle lighting control, the accuracy, effectiveness, and practicality of lighting control are improved.

[0070] Figure 2 This is a schematic flowchart illustrating a vehicle lighting control method according to other embodiments of the present disclosure. Figure 2As shown, the vehicle lighting control method includes steps S210 to S280. Figure 2 exist Figure 1 Based on the illustrated process, additional processing steps have been added. The following mainly focuses on... Figure 2 The newly added processing steps are explained in detail.

[0071] In step S210, the current lighting control mode of the vehicle is obtained.

[0072] In some embodiments, the vehicle lighting control method is performed by a vehicle lighting control device.

[0073] If the lighting control mode is in automatic mode, proceed to step S220; if the lighting control mode is in manual mode, proceed to step S280.

[0074] In step S220, it is determined whether an image sensor is installed.

[0075] In some embodiments, the vehicle lighting control device queries the vehicle's image sensor configuration information and determines whether the vehicle is equipped with an image sensor based on the query results. Alternatively, the vehicle lighting control device may use other methods to determine whether the vehicle is equipped with an image sensor. For example, it may determine whether an image sensor is installed by sending a request message to the image sensor and determining whether a response message is received from the image sensor within a set time period.

[0076] If it is confirmed that an image sensor is installed, proceed to step S230; otherwise, proceed to steps S270 and S280.

[0077] In other embodiments of this disclosure, step 250 is performed if it is determined that no image sensor is installed.

[0078] In this embodiment of the disclosure, by first determining whether an image sensor is installed when the current lighting control mode is automatic, and then switching to manual mode when it is confirmed that no image sensor is installed, the vehicle lighting control needs in more scenarios can be met, and the operability of vehicle lighting control can be improved.

[0079] In step S230, it is determined whether the image sensor is faulty.

[0080] If it is determined that the image sensor is not faulty, proceed to step S240; otherwise, proceed to step S250.

[0081] In step S250, it is determined whether a positioning system is installed.

[0082] In some embodiments, the vehicle lighting control device queries the configuration information of the vehicle's positioning system and determines whether the vehicle has a positioning system installed based on the query results. Alternatively, the vehicle lighting control device may use other methods to determine whether the vehicle has a positioning system installed.

[0083] If it is confirmed that a positioning system is installed, proceed to step S260; otherwise, proceed to steps S270 and S280.

[0084] In this embodiment of the disclosure, after determining that lighting control cannot be performed based on an image sensor, it first determines whether a positioning system is installed, and if it is confirmed that no positioning system is installed, it switches to manual mode, which can meet the vehicle lighting control needs in more scenarios and further improve the operability of vehicle lighting control.

[0085] In step S260, the vehicle's lighting system is controlled based on the vehicle location information collected by the positioning system and the current time information.

[0086] In step S270, switch to manual mode.

[0087] In step S280, the vehicle's lighting system is controlled according to the user's operation.

[0088] In some embodiments, step S280 includes: controlling the vehicle's lighting system to turn on after detecting a user's command to turn on the lights.

[0089] For example, when a user inputs a command to turn on the lights through the human-machine interface of the vehicle lighting control device, the vehicle's lighting system is turned on.

[0090] For example, upon detecting a user's voice command to turn on the lights, the vehicle's lighting system can be activated.

[0091] For example, when a user presses or touches an electronic switch in the lighting system, the vehicle's lighting system can be turned on.

[0092] In this embodiment, by combining manual and automatic lighting control, the operability of vehicle lighting control is improved, meeting the needs of vehicle lighting control in more scenarios. Simultaneously, by combining an image sensor with a positioning system for automatic lighting control, and prioritizing the use of the image sensor for vehicle lighting control, the accuracy, effectiveness, and practicality of lighting control are improved. Furthermore, by incorporating multiple judgment logics into vehicle lighting control, such as whether an image sensor is installed and whether the image sensor is faulty, the operability of vehicle lighting control can be further improved, meeting the needs of vehicle lighting control in more scenarios.

[0093] Figure 3 This is a schematic diagram of the structure of a vehicle lighting control device according to some embodiments of the present disclosure. Figure 3 As shown, the vehicle lighting control device 300 includes an acquisition module 310, a determination module 320, a first control module 330, and a second control module 340.

[0094] The acquisition module 310 is configured to acquire the current lighting control mode of the vehicle.

[0095] The lighting control modes include automatic mode and manual mode.

[0096] The determination module 320 is configured to determine whether the image sensor is faulty when the vehicle's current lighting control mode is automatic.

[0097] The first control module 330 is configured to control the vehicle's lighting system based on the images acquired by the image sensor, provided that the image sensor is not faulty.

[0098] The second control module 330 is configured to control the vehicle's lighting system based on the vehicle's location information collected by the positioning system and the current time information in the event of a malfunction in the image sensor.

[0099] In this embodiment, the combination of manual and automatic lighting control using the above-described device improves the operability of vehicle lighting control and meets the needs of vehicle lighting control in more scenarios. Simultaneously, by combining an image sensor with a positioning system for automatic lighting control, and prioritizing the use of the image sensor for vehicle lighting control, the accuracy, effectiveness, and practicality of lighting control are improved.

[0100] Figure 4 This is a schematic diagram of the structure of a vehicle lighting control device according to other embodiments of the present disclosure. For example... Figure 4 As shown, the vehicle lighting control device includes an electronic monitor 401, an image controller 402, and a positioning controller 403.

[0101] Electronic monitor 401 is configured to acquire the vehicle's current lighting control mode. The lighting control mode includes automatic mode and manual mode.

[0102] The electronic monitor 401 is also configured to send a first request to the image controller 402 when the vehicle’s current lighting control mode is automatic.

[0103] In some embodiments, the image controller 402 is configured to, upon receiving a first request, determine whether the image sensor is faulty; if the image sensor is not faulty, determine whether to turn on the vehicle's lighting system based on the image acquired by the image sensor; if it is determined that the vehicle's lighting system should be turned on, send a first turn-on command corresponding to the first request to the electronic monitor 401; and if the image sensor is faulty, send a fault warning message to the electronic monitor 401.

[0104] In some embodiments, the image controller 402 determines whether the image sensor is faulty by: determining whether the power supply state and signal transmission state of the image sensor are normal; if both the power supply state and signal transmission state of the image sensor are normal, determining that the image sensor is not faulty; otherwise, determining that the image sensor is faulty.

[0105] In some embodiments, the image controller 402 determines whether the image sensor is faulty by: determining whether the power supply state and signal transmission state of the image sensor are normal; if both the power supply state and signal transmission state of the image sensor are normal, determining whether the image sensor is occluded and whether the degree of contamination of the image sensor is greater than a contamination degree threshold; if the image sensor is not occluded and the degree of contamination of the image sensor is less than the contamination degree threshold, determining that the image sensor is not faulty; otherwise, determining that the image sensor is faulty.

[0106] In some embodiments, the image sensor includes multiple cameras, for example Figure 4 The images of cameras 1 (405), 2 (406), 3 (407), and 4 (408) are shown. The image controller 402 determines whether to turn on the vehicle's lighting system based on the images collected by the image sensors. This includes: determining the ambient light intensity corresponding to each camera based on the images collected by each of the multiple cameras; and determining to turn on the vehicle's lighting system when the ambient light intensity corresponding to at least M cameras is less than a first light intensity threshold, where M is an integer greater than or equal to 2.

[0107] In some embodiments, the image sensor includes multiple cameras, and the vehicle's lighting system includes multiple light groups. The image controller 402 determines whether to activate the vehicle's lighting system based on images acquired by the image sensor by: determining the ambient light intensity corresponding to each camera based on images acquired by each of the multiple cameras; determining to activate N1 light groups in the vehicle's lighting system if the ambient light intensity corresponding to at least M cameras is greater than or equal to a second light intensity threshold and less than a first light intensity threshold; and determining to activate N2 light groups in the vehicle's lighting system if the ambient light intensity corresponding to at least M cameras is less than the second light intensity threshold, wherein N2 and N1 are both integers, and N2 is greater than N1. Then, the image controller 402 sends a first activation command carrying an indication of the number of light groups to be activated to the electronic monitor 401.

[0108] The electronic monitor 401 is also configured to control the activation of the vehicle's lighting system according to the first activation command received from the image controller 402 in response to the first activation command corresponding to the first request.

[0109] In some embodiments, the vehicle's lighting system includes multiple light groups, and the first activation command includes indication information of the number of light groups to be activated. The electronic monitor 401 controls the activation of the vehicle's lighting system according to the first activation command by: the electronic monitor 401 forwarding the first activation command to the switch panel 404 to instruct the switch panel 404 to activate the light groups in the vehicle's lighting system.

[0110] The electronic monitor 401 is also configured to send a second request to the positioning controller 403 upon receiving a fault indication message corresponding to the first request from the image controller 402.
