[0032] In this disclosure, unless otherwise specified, the use of terms such as "first" and "second" to describe various elements is not intended to limit the positional relationship, temporal relationship, or importance relationship of these elements. Such terms are only used to distinguish one element from another. In some examples, the first element and the second element may refer to the same instance of the element, while in some cases, based on the context of the description, they may also refer to different instances.

[0033] The terms used in the description of the various examples described in this disclosure are for the purpose of describing specific examples only and are not intended to be limiting. Unless the context clearly indicates otherwise, if the number of elements is not specifically limited, the element can be one or more. As used herein, the term "plurality" means two or more, and the term "based on" should be interpreted as "based at least in part on". In addition, the terms "and / or" and "at least one of..." cover any one of the listed items and all possible combinations.

[0034] For example, autonomous driving systems at Level 3 (capable of monitoring the driving environment while the driver is not in the loop within the operational design domain (ODD)) and above (e.g., Level 4 and Level 5 autonomous driving systems, which provide autonomous driving and redundant backup capabilities in completely driver-out conditions), must be capable of covering low-light scenarios (e.g., at night). Existing autonomous driving solutions typically use visual sensors (e.g., cameras) along with high-definition maps or lidar to output the vehicle's surroundings (e.g., lane markings). Visual sensors are highly dependent on light intensity. During nighttime driving, if light is lost, the vehicle must rely on HD maps or lidar to obtain lane data to maintain normal driving (e.g., lateral centering). As is well known, HD maps are limited by positioning accuracy and map updates and cannot guarantee accurate lane data in all scenarios. LiDAR is also significantly affected by environmental factors such as rain, fog, and lights. Therefore, if light is lost during driving, the autonomous vehicle may experience inaccurate perception of the surrounding environment, leading to abnormal driving and violations of safe driving objectives, such as lateral control errors.

[0035] In autonomous driving, the vehicle's lateral control safety level is the highest (ASIL D). The corresponding safety goal is to avoid excessive lateral control, insufficient lateral control, loss of lateral control, opposite lateral control direction, and unexpected lateral control. A major cause of lateral control errors in autonomous vehicles is the unexpected loss or error of lane markings due to loss of external lighting. To meet these safety goals, based on reasonable safety level decomposition rules, the lighting system's safety level should be no lower than ASIL B. At the same time, a redundant design of the lighting system is required to prevent the sudden loss of headlights during autonomous driving.

[0036] In the related art, redundancy design solutions for lighting systems include the following three: a redundancy solution with separate left and right headlights; a redundancy solution with a matrix light cluster; and a redundancy solution with independent backup light clusters and light control modules (including the left and right headlight control modules) for each of the left and right headlights. However, the redundancy solution with separate left and right headlights can result in common-cause failures between the lights, drive relays, and light control modules (for example, a light control module failure can completely disable the redundancy solution). Furthermore, even with one remaining headlight, insufficient illumination of the road ahead can lead to inaccurate lane line detection by the camera. The light control module in the matrix light cluster redundancy solution often cannot diagnose every failure mode for every LED in the cluster. Therefore, multiple LEDs may fail without the light control module being aware of the failure, thus affecting the actual lighting redundancy effect. The redundancy solution with independent backup light clusters and light control modules for the left and right headlights is complex, costly, and wastes significant hardware components.

[0037] In light of this, the present disclosure provides a vehicle lighting control redundancy design method and system that meets the functional safety requirements of L3 and above autonomous driving. By designing a unified redundancy solution for the left and right headlights (i.e., providing two regional control modules as redundant backup solutions for controlling the left and right headlight control modules, as well as the front grille light control modules), and using the front grille light as a backup solution for the left and / or right headlights, the present disclosure can avoid common cause failures between the redundant solutions, thereby relatively simply and reliably implementing independent redundant backup solutions for the lighting system, thereby increasing the safety and reliability of the lighting system. This can prevent the sudden loss of lights during vehicle operation, which could lead to inaccurate output from related sensors, thereby ensuring the safety and reliability of vehicle driving.

[0038] Exemplary embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0039] Figure 1 is a schematic diagram illustrating an example system 100 in which the various methods described herein may be implemented, according to an exemplary embodiment.

[0040] refer to Figure 1 The system 100 includes an in-vehicle system 110, a server 120, and a network 130 that communicatively couples the in-vehicle system 110 and the server 120.

[0041] The in-vehicle system 110 includes a display 114 and an application (APP) 112 that can be displayed via the display 114. The application 112 can be an application installed by default on the in-vehicle system 110 or downloaded and installed by the user 102, or a mini-program that is a lightweight application. If the application 112 is a mini-program, the user 102 can directly run the application 112 on the in-vehicle system 110 by searching for the application 112 in the host application (e.g., by the name of the application 112, etc.) or scanning a graphical code (e.g., a barcode, a QR code, etc.) of the application 112, without having to install the application 112. In some embodiments, the in-vehicle system 110 may include one or more processors and one or more memories (not shown), and the in-vehicle system 110 is implemented as an in-vehicle computer. In some embodiments, the in-vehicle system 110 may include more or fewer display screens 114 (e.g., no display screen 114), and / or one or more speakers or other human-computer interaction devices. In some embodiments, the in-vehicle system 110 may not communicate with the server 120.

[0042] Server 120 may represent a single server, a cluster of multiple servers, a distributed system, or a cloud server that provides basic cloud services (such as cloud database, cloud computing, cloud storage, cloud communication). Figure 1 1 , the server 120 is shown communicating with only one in-vehicle system 110 , but the server 120 can provide background services for multiple in-vehicle systems at the same time.

[0043] Network 130 allows for wireless communication and information exchange between vehicles and X (where "X" refers to a vehicle, road, pedestrian, or the Internet, etc.) according to agreed-upon communication protocols and data exchange standards. Examples of network 130 include a local area network (LAN), a wide area network (WAN), a personal area network (PAN), and / or a combination of communication networks such as the Internet. Network 130 can be a wired or wireless network. In one example, network 130 can be an in-vehicle network, an inter-vehicle network, and / or an in-vehicle mobile Internet.

[0044] Figures 2a to 2c is a schematic diagram of a lighting system 200 for a vehicle 2000 according to some exemplary embodiments; Figure 3 The diagram shows Figure 2a Schematic diagram of the structure of the lighting system 200. Figures 2a to 2c As shown, vehicle 2000 may include lighting system 200. Figures 2a to 2cAs shown, the lighting system 200 may include two headlights 210 and 220 (e.g., a left headlight 210 and a right headlight 220), a front grille light 230, and a first zone control module 251 and a second zone control module 252. Each headlight has a headlight control module (e.g., a left headlight control module 241 and a right headlight control module 242) configured to control the on / off state of the corresponding headlight. The front grille light 230 is configured to serve as a replacement and / or supplemental light source for at least one of the two headlights and has a front grille light control module 243 configured to control its on / off state. The first zone control module 251 and the second zone control module 252 are communicatively coupled to the headlight control module and the front grille light control module 243 of the two headlights, respectively, and are configured to control the headlight control module and the front grille light control module 243 of the two headlights. Under normal working conditions, the headlight control modules of the two headlights are controlled by the first area control module 251 or respectively by the first area control module 251 and the second area control module 252. When one of the first area control module 251 and the second area control module 252 that is activated under normal working conditions fails, the other one of the first area control module 251 and the second area control module 252 is activated. Figure 3 In the example, specifically, Figure 3 As shown, the left headlight control module 241 is configured to control the on / off switching of the left headlight 210. The right headlight control module 242 is configured to control the on / off switching of the right headlight 220. The front grille light control module 243 is configured to control the on / off switching of the front grille light 230. The first zone control module 251 is configured to control the left headlight control module 241, the right headlight control module 242, and the front grille light control module 243. The second zone control module 252 is configured to control the left headlight control module 241, the right headlight control module 242, and the front grille light control module 243.

[0045] In the above embodiment, the first and second regional control modules can each independently control the left and right headlight control modules. This allows the first and second regional control modules to back up each other to control the left and right headlight control modules. This allows the first and second regional control modules to control the left and right headlight control modules, ensuring that if one regional control module, its connected control module, or its communication link fails, the other regional control module can be used to activate the headlights. Furthermore, the first and second regional control modules can also control the front grille lights as needed, providing redundancy in the event of a single-point failure (one headlight extinguished) or a dual-point failure (both headlights extinguished) in the lighting system. This mitigates common cause failures, such as those caused by failures in the left and right headlight control modules. This allows for a relatively simple and reliable implementation of independent redundancy for the lighting system, enhancing the safety and reliability of the lighting system. This prevents inaccurate sensor outputs caused by a sudden loss of lighting during vehicle operation, ensuring safe and reliable driving.

[0046] In some embodiments, the front grille light is configured to serve as a replacement and / or supplemental light source for at least one of the left and right headlights. This can be achieved by configuring the front grille light's luminous intensity, illumination distance, and other parameters. When the front grille light 230 serves as a replacement for the left and / or right headlights 210 and / or 220, parameters such as the luminous intensity and illumination distance (i.e., projection distance) of the front grille light can be set to be equal to or close to those of the left and / or right headlights to meet the vehicle's headlight lighting standards. In some examples, to meet the requirements of autonomous driving, the illumination distance of the front grille light can also be set based on the vehicle's autonomous driving level. For example, when the vehicle's autonomous driving level is L3, the illumination distance of the front grille light can be set to greater than or equal to 30 meters, or to other values ​​as needed. For another example, when the vehicle's autonomous driving level is L4, the illumination distance of the front grille light can be set to greater than or equal to 60 meters, or to other values ​​as needed. For another example, when the vehicle's autonomous driving level is L5, the front grille light's illumination distance can be set to 80 meters or greater, or to other values ​​as needed. When the front grille light 230 serves as a supplemental light source for the left headlight 210 and / or the right headlight 220, the front grille light's illumination distance and luminous intensity can also be set according to the above embodiment, or to other values ​​as needed to supplement the left or right headlight.

[0047] Additionally or alternatively, the front grille light is configured to be used as a substitute light source and / or supplementary light source for at least one of the left headlight and the right headlight, and this can also be achieved by configuring the shape and color of the light emitted by the front grille light. The front grille light 230 can be configured to project multiple independent light beams. Specifically, the portion of the front grille light 230 adjacent to each of the two headlights can project at least one independent light beam. For example, Figures 2a to 2c As shown, the front grille light 230 may include a portion 231 proximate to the left headlight 210 and a portion 232 proximate to the right headlight 220. The portion 231 proximate to the left headlight of the front grille light can project at least one independent light beam, and the portion 232 proximate to the right headlight of the front grille light can project at least one independent light beam. In some examples, the front grille light 230 may be an LED light, for example. The light beam projected by the front grille light 230 may be in any shape, such as circular, square, or diamond. Furthermore, the light beam projected by the front grille light 230 may be incandescent light or other colors that meet certain illumination distance requirements.

[0048] In some embodiments, the front grille light control module 243 may include a front grille light control unit (e.g., a microcontroller unit (MCU), etc.), a driver, a light actuator, etc. The portion 231 near the left headlight 210 and the portion 232 near the right headlight 220 may be controlled individually or simultaneously by the front grille light control module 243 as needed.

[0049] In some embodiments, at least one of the left headlight control module 241 and the right headlight control module 242 may include a headlight control unit (e.g., a microcontroller unit MCU, etc.), a drive and light actuator, etc., so as to control / drive the opening and closing of the left headlight and the right headlight respectively.

[0050] In some embodiments, as Figure 3As shown, the lighting system 200 may further include a first communication link L1, a second communication link L2, a third communication link L3, a fourth communication link L4, a fifth communication link L5, and a sixth communication link L6. The first communication link L1 is used to transmit signals between the first regional control module 251 and the left headlamp control module 241, and between the left headlamp control module 241 and the left headlamp 210. The second communication link L2 is used to transmit signals between the first regional control module 251 and the right headlamp control module 242, and between the right headlamp control module 242 and the right headlamp 220. The third communication link L3 is used to transmit signals between the second regional control module 252 and the left headlamp control module 241, and between the left headlamp control module 241 and the left headlamp 210. The fourth communication link L4 is used to transmit signals between the second regional control module 252 and the right headlamp control module 242, and between the right headlamp control module 242 and the right headlamp 220. The fifth communication link L5 is used to transmit signals between the first area control module 251 and the front grille light control module 243, and between the front grille light control module 243 and the front grille light 230. The sixth communication link L6 is used to transmit signals between the second area control module 252 and the front grille light control module 243, and between the front grille light control module 243 and the front grille light 230. The above embodiment can implement a redundant backup solution for the communication links used to control the left and right headlights, as well as the front grille lights. For example, the first and third communication links used to control the left headlights can serve as redundant backup links for each other. In another example, the second and fourth communication links used to control the right headlights can serve as redundant backup links for each other. For another example, the fifth and sixth communication links used to control the front grille lights can serve as redundant backup links for each other, and can also serve as redundant backup links for at least one of the first, second, third, and fourth communication links. Therefore, when one or more communication links fail, the backup communication link can be enabled to turn on the headlights and / or front grille lights to ensure normal driving of the vehicle.

[0051] In some embodiments, the lighting system 200 may further include a first power supply 261 and a second power supply 262. The first power supply 261 is used to power the first regional control module 251, and the second power supply 262 is used to power the second regional control module 252. This allows for redundant backup between the first and second power supplies. For example, if the first power supply fails, the second power supply can be used to power the second regional control module, restoring the left or right headlights. Alternatively, the first regional control module can be powered by the second power supply, or by a combination of the first and second power supplies. The second regional control module can also be powered by the first power supply, or by a combination of the first and second power supplies. Using a combination of the first and second power supplies can further enhance system redundancy. For example, if the first regional control module is powered by a combination of the first and second power supplies, in the event of a failure of the first power supply, the second power supply can be used to power the first regional control module, eliminating the need to switch regional control modules. In some examples, the power provided by the first and second power supplies can be equal or different.

[0052] In some embodiments, the first regional control module 251 can be used to supply power to the communication links used by the first regional control module (e.g., the first communication link L1, the second communication link L2, and the fifth communication link L5). Correspondingly, the second regional control module 252 can be used to supply power to the communication links connected to the second regional control module (e.g., the third communication link L3, the fourth communication link L4, and the sixth communication link L6).

[0053] In some embodiments, each of the left headlight control module 241, the right headlight control module 242, and the front grille light control module 243 is selectively powered by one of the first power source 261 and the second power source 262. In other words, each of the left headlight control module, the right headlight control module, and the front grille light control module can be powered by a combination of the first power source and the second power source. In the lighting system 200, regardless of which communication link is used to control the left headlight, right headlight, and front grille light, they must all be controlled through the left headlight control module, the right headlight control module, and the front grille light control module, respectively. Therefore, the first power source and the second power source are used to provide a combined power supply to the left headlight control module, the right headlight control module, and the front grille light control module. In the event of a power failure, the other power source can still be used to power the left headlight control module, the right headlight control module, and the front grille light control module, ensuring normal operation of these lighting control modules.

[0054] In some other embodiments, each of the left headlight control module 241, the right headlight control module 242, and the front grille light control module 243 can be selectively powered by one of the first region control module 251 and the second region control module 252. In other words, each of the left headlight control module, the right headlight control module, and the front grille light control module can be powered by a combination of the first and second region control modules, thereby ensuring the normal operation of these control modules.

[0055] Figure 4 is a diagram illustrating a vehicle (eg, Figures 2a to 2c The lighting system of the vehicle 2000 (eg, Figures 2a to 2c as well as Figure 3 The control method 400 can be executed on the vehicle side, specifically, for example, at the control device in the vehicle, that is, the execution subject of the control method 400 is the control device in the vehicle. Figures 2a to 2c 、 Figure 3 and Figure 4 Each step of the control method 400 is described in detail.

[0056] like Figure 4 As shown, the control method 400 may include: step 410, determining whether to turn on at least one of the two headlights; step 420, in response to determining that at least one headlight is turned on, causing the lighting system 200 to perform a first operation to turn on the first headlight; step 430, in response to at least one headlight not being turned on, obtaining a fault status of the lighting system 200, and based on the fault status, causing the lighting system 200 to perform a second operation to turn on the front grille light 230 and / or turn on at least one headlight again.

[0057] The at least one headlight mentioned above may be a left headlight or a right headlight. Figures 2a to 2c In the example, it is assumed that the at least one headlight is the left headlight 210. At this time, the control device in the vehicle 2000 causes the lighting system 200 to perform a first operation to turn on the left headlight 210. If the left headlight 210 in the lighting system 200 is not turned on, the lighting system 200 performs a corresponding backup operation based on the fault state of the lighting system to turn on the front grille light 230 (used as an alternative light source, such as Figure 2c ), or turn on the left headlight 210 again (the light status is as shown Figure 2a ), or the front grille lamp 230 is turned on (used as a supplementary light source) and the left front headlamp 210 is turned on again (as shown in FIG. Figure 2bThe case where at least one headlight refers to a right headlight is the same as the case where the left headlight is used, and for the sake of brevity, detailed description thereof will not be given here.

[0058] In addition, at least one headlight may also refer to both the left headlight and the right headlight. At this time, the at least one headlight not being turned on in step 430 may include the left headlight not being turned on, the right headlight not being turned on, or both the left headlight and the right headlight not being turned on. Accordingly, turning at least one headlight on again may refer to turning on again the headlight that was not successfully turned on before, either the left headlight or the right headlight. Figures 2a to 2c In the example of FIG, it is assumed that the at least one headlight refers to both the left headlight 210 and the right headlight 220. At this time, the control device in the vehicle 2000 causes the lighting system 200 to perform a first operation to turn on the left headlight 210 and the right headlight 220. If at least one headlight is not turned on, that is, the left headlight 210 is not turned on, then the lighting system is caused to perform a corresponding backup operation based on the fault state of the lighting system to turn on the front grille light 230 (e.g., Figure 2c ), or at least one headlight is turned on again, that is, the left headlight 210 is turned on again (the light state is as shown in FIG. Figure 2a ), or the front grille lamp 230 is turned on and at least one headlamp is turned on again, that is, the left headlamp 210 is turned on again (as shown in FIG. Figure 2b shown).

[0059] The lighting system fault status may include at least one of a first-region control module or a second-region control module fault, a first power supply or a second power supply fault, a first communication link and / or a second communication link fault, a left headlight control module fault and / or a right headlight control module fault, etc. The vehicle control device may detect the lighting system fault on its own or determine the lighting system fault status based on a fault report sent by the lighting system.

[0060] The above embodiment enables, if the lighting system fails to activate the left and / or right headlights using the first operation, to activate the backup operation to reactivate the headlights or the front grille lights as a replacement or supplemental light. This improves the safety and reliability of the lighting system, thereby preventing the sudden loss of lights during vehicle operation and resulting in inaccurate sensor outputs, thereby ensuring safe and reliable vehicle driving.

[0061] In some embodiments, a light operation instruction (which may include a light on instruction and a light off instruction) for turning on at least one headlight may be generated by a user pressing or touching a headlight on button. For example, a light operation instruction for turning on at least one headlight may be generated in response to sensing that a user in a vehicle presses or touches a headlight on button in the vehicle, and the light operation instruction is sent to a vehicle control device; or, a light operation instruction may be generated by turning on the headlight function of a smart terminal device (such as a mobile phone, smart watch, etc.) that is connected to the vehicle terminal for communication. At this time, in step 410, whether to turn on at least one headlight may be determined based on whether the light operation instruction is received. Alternatively, whether to turn on at least one headlight may be determined based on the lighting conditions of the surrounding environment sensed by the vehicle sensor.

[0062] In some embodiments, in step 420, the vehicle control device may cause the lighting system 200 to perform a first operation to turn on at least one headlamp by sending a lighting operation request to the lighting system. The lighting operation request may simply include at least one headlamp turn-on instruction. In this case, the lighting system itself determines the specific actions of the first operation to turn on at least one headlamp. Alternatively, the lighting operation request may include at least one headlamp turn-on instruction and instructions related to the first operation, causing the lighting system to perform the first operation.

[0063] In some embodiments, step 430 may include: in response to at least one headlamp not being turned on, sending an instruction regarding the second operation to the lighting system, causing the lighting system to perform the second operation, thereby turning on the front grille lamps and / or turning on the at least one headlamp again. Alternatively, the lighting system may determine the specific action of the second operation and send a request to the vehicle control device to perform the second operation. In this case, step 430 may include: in response to at least one headlamp not being turned on and receiving the request to perform the second operation, sending an approval indication to the lighting system, causing the lighting system to perform the second operation, thereby turning on the front grille lamps and / or turning on the at least one headlamp again.

[0064] In some embodiments, the control method 400 may further include, in response to determining to turn on at least one headlight, causing the lighting system 200 to perform a third operation to turn on a portion of the front grille lights 230 adjacent to the at least one headlight. This allows the front grille lights to be used as supplementary light sources for the at least one headlight, thereby improving the lighting effect of the headlights and ensuring safer and more reliable driving of the vehicle.

[0065] In some embodiments, the first operation may be an action executed to turn on the left and / or right headlights when the lighting system is not faulty. The third operation may be an action executed to turn on the front grille lights when the lighting system is not faulty. In some examples, the first and third operations may be as shown in Table 1 below. Table 1 shows the components involved in the control actions executed by the lighting system 200 to turn on the headlights and front grille lights under normal conditions.

[0066] Table 1 Control actions of the lighting system 200 in normal state

[0067]

[0068] As shown in Table 1, if at least one headlamp is a left headlamp, the first operation may include causing the first regional control module to control the left headlamp control module using a first communication link. If at least one headlamp is a right headlamp, the first operation may include causing the first regional control module to control the right headlamp control module using a second communication link. If at least one headlamp is both a left and a right headlamp, the first operation may include causing the first regional control module to control the left headlamp control module using the first communication link and causing the first regional control module to control the right headlamp control module using the second communication link. The third operation may include causing the first regional control module to control the front grille light control module using a fifth communication link. It should be understood that in lighting system 200, the first regional control module is powered by a first power source, while the second regional control module is powered by a second power source. Therefore, the first and third operations may also include causing the first regional control module to be powered by the first power source.

[0069] In some other examples, the first operation and the third operation may be as shown in the following Table 2. Table 2 shows components involved in the lighting system 200 executing control actions for turning on the headlights and the front grille lights in a normal state.

[0070] Table 2 Control actions of the lighting system 200 in normal state

[0071]

[0072] As shown in Table 2, if at least one headlamp is a left headlamp, the first operation may include causing the first regional control module to control the left headlamp control module using a first communication link. If at least one headlamp is a right headlamp, the first operation may include causing the second regional control module to control the right headlamp control module using a fourth communication link. If at least one headlamp is both a left and a right headlamp, the first operation may include causing the first regional control module to control the left headlamp control module using the first communication link and causing the second regional control module to control the right headlamp control module using a fourth communication link. The third operation may include causing the first regional control module to control the front grille light control module using a fifth communication link. Furthermore, in lighting system 200, the first regional control module is powered by a first power source, while the second regional control module is powered by a second power source. Therefore, the first operation may also include causing the first regional control module to be powered by the first power source and / or causing the second regional control module to be powered by the second power source. The third operation may also include causing the first regional control module to be powered by the first power source.

[0073] The control actions of the lighting system 200 in the normal state described above are merely exemplary. The first operation may be any one or a combination of the aforementioned actions for turning on the left and / or right headlights. For example, the first operation may include causing the second regional control module to control the left headlight control module using the third communication link and / or causing the second regional control module to control the right headlight control module using the fourth communication link. The present disclosure is not limited thereto. Similarly, the third operation may include causing the second regional control module to control the front grille light control module using the sixth communication link.

[0074] Furthermore, the second operation may be an alternative operation, different from the first operation, for turning on the left and / or right headlights when a lighting system fault occurs. For example, if the first operation uses the control actions shown in Table 1, the second operation may be as shown in Table 3 below. Table 3 shows the components involved in the second operation that the lighting system can perform to turn on the front grille lights and / or restart at least one headlight under different fault conditions, based on the control actions of the lighting system under normal conditions in Table 1.

[0075] Table 3 Control actions of the lighting system 200 in a fault state

[0076]

[0077] As shown in Table 3, for example, if the fault condition includes a first power supply failure and at least one headlamp is a left headlamp, the second operation may include powering the second regional control module from the second power supply and causing the second regional control module to control the left headlamp control module via the third communication link. Alternatively or additionally, the second operation may also include causing the second regional control module to control the front grille light control module via the sixth communication link. For another example, if at least one headlamp is a left headlamp and the fault condition includes a first communication link failure, the second operation may include powering the second regional control module from the second power supply and causing the second regional control module to control the left headlamp control module via the third communication link. Alternatively or additionally, the second operation may include powering the first regional control module from the first power supply and causing the first regional control module to control the front grille light control module via the fifth communication link, or powering the second regional control module from the second power supply and causing the second regional control module to control the front grille light control module via the sixth communication link. In other words, under a specific fault condition, the second operation may select any one of the operations listed in Table 3, or a combination of any two of the operations listed in the rows associated with that specific fault condition.

[0078] Furthermore, when the first operation uses the control actions shown in Table 2, the second operation may be as shown in Table 4 below. Table 4 shows the components involved in the second operation for turning on the front grille lamps and / or turning on at least one headlamp again, which can be performed by the lighting system under different fault conditions, based on the control actions of the lighting system under normal conditions in Table 2.

[0079] Table 4 Control actions of lighting system 400 in fault state

[0080]

[0081]

[0082] As shown in Table 3, for example, if at least one headlamp is a right headlamp and the fault condition includes a failure of the second power supply or the second regional control module, the second operation may include powering the first regional control module from the first power supply and causing the first regional control module to control the right headlamp control module via the second communication link. Alternatively or additionally, the second operation may also include causing the first regional control module to control the front grille light control module via the fifth communication link. For another example, if at least one headlamp is a right headlamp and the fault condition includes a failure of the fourth communication link, the second operation may include powering the first regional control module from the first power supply and causing the first regional control module to control the right headlamp control module via the second communication link. Alternatively or additionally, the second operation may include powering the first regional control module from the first power supply and causing the first regional control module to control the front grille light control module via the fifth communication link, or powering the second regional control module from the second power supply and causing the second regional control module to control the front grille light control module via the sixth communication link. In other words, under a specific fault condition, the second operation may select any one of the operations listed in Table 4, or a combination of any two of the operations listed in the rows associated with that specific fault condition.

[0083] It should be understood here that the present disclosure is not limited to the above examples. According to actual needs, a first operation for turning on at least one headlamp in a normal state and an alternative operation different from the first operation for turning on at least one headlamp again and / or turning on the front grille light in a fault state can be selected in the lighting system.

[0084] In some embodiments, the first operation includes powering a first regional control module from a first power source, and the fault status indicates a failure of the first power source. In this case, based on the fault status, causing the lighting system to perform a second operation to activate the front grille lamps and / or at least one headlamp again includes: based on the failure of the first power source, causing the lighting system to power a second regional control module from a second power source to activate at least the at least one headlamp again. For example, using Tables 2 and 4 as an example, assuming the at least one headlamp is the left headlamp 210, the first operation includes powering the first regional control module 251 from the first power source 261. In this case, if the fault status indicates a failure of the first power source 261, the second operation may include powering the second regional control module 252 from the second power source 262 to activate the left headlamp 210 again. Additionally or alternatively, the first operation may include powering the first zone control module from a first power source and powering the second zone control module from a second power source, the fault status indicating a fault in one of the first and second power sources, and, based on the fault status, causing the lighting system to perform a second operation to activate the front grille lamps and / or reactivate at least one headlamp may include, based on the fault in one of the first and second power sources, causing the lighting system to power the first and second zone control modules from the other of the first and second power sources, thereby reactivating at least the at least one headlamp. For example, using Tables 2 and 4 above as an example, assuming the at least one headlamp is the right headlamp 220, the first operation may include powering the second zone control module 252 from the second power source 262. In this case, if the fault status indicates a fault in the second power source 262, the second operation may include powering the first zone control module 251 from the first power source 261, thereby reactivating the right headlamp 220. The above embodiment can realize that when one of the first power supply or the second power supply fails, the other one that is not failed is used to power the regional control module to turn on the corresponding headlights and / or front grille lights, thereby ensuring normal driving of the vehicle.

[0085] In some other embodiments, based on the fault state, causing the lighting system to perform a second operation to turn on the front grille lights and / or at least one headlamp to be turned on again may also include: based on the first power supply failure, causing the lighting system to perform an action of supplying power to the second area control module by the second power supply to at least turn on the front grille lights, or, based on the second power supply failure, causing the lighting system to perform an action of supplying power to the first area control module by the first power supply to at least turn on the front grille lights.

[0086] In some embodiments, upon a failure of the first power supply, causing the lighting system to power the second zone control module from the second power supply to reactivate at least one headlamp includes: upon a failure of the first power supply, causing the lighting system to power the second zone control module from the second power supply to reactivate at least one headlamp and to activate a portion of the front grille lamp proximate to the at least one headlamp. Furthermore, upon a failure of one of the first and second power supplies, causing the lighting system to power the first and second zone control modules powered by the other power supply to reactivate at least one headlamp includes: upon a failure of one of the first and second power supplies, causing the lighting system to power the first and second zone control modules powered by the other power supply to reactivate at least one headlamp and to activate a portion of the front grille lamp proximate to the at least one headlamp. These embodiments enable the use of the undamaged first or second power supply to power the zone control modules to activate the corresponding headlamps and front grille lamps in the event of a failure in either the first or second power supply, thereby further ensuring normal vehicle operation. In the above embodiment, only the portion of the front grille lamp close to at least one headlamp is turned on. Alternatively, the entire front grille lamp may be turned on, and the present disclosure is not limited thereto.

[0087] In some embodiments, the first operation includes causing one of the first and second regional control modules corresponding to at least one headlamp to control one of the at least one headlamp, and a fault status indicates a fault in the first or second regional control module corresponding to the at least one headlamp. Based on the fault status, causing the lighting system to perform a second operation to activate the front grille lamps and / or reactivate the at least one headlamp may include, based on the fault in the first or second regional control module corresponding to the at least one headlamp, causing the lighting system to at least activate the other of the first or second regional control module to control the at least one headlamp, thereby reactivating the at least one headlamp. For example, using Tables 2 and 4 above as an example, if the at least one headlamp is the left headlamp 210, the first operation includes causing the first regional control module 251 to control the left headlamp using the first communication link L1. In this case, if the fault status indicates a fault in the first regional control module 251, the second operation may include causing the second regional control module 252 to control the left headlamp using the third communication link L3, thereby reactivating the left headlamp 210. The above embodiment enables, in the event of a failure in one of the first and second zone control modules, the unfaulted other zone control module to activate the corresponding headlights, thereby ensuring normal vehicle driving. Additionally or alternatively, the above-described operation of causing the lighting system to perform a second operation based on the fault state to activate the front grille lights and / or at least one headlight again may include: based on a failure in the zone control module corresponding to the at least one headlight, causing the lighting system to at least execute an operation of the other of the first and second zone control modules to control the front grille light control module, thereby activating the front grille lights (e.g., a portion of the front grille lights adjacent to the at least one headlight).

[0088] In some embodiments, the first operation includes causing one of the first and second regional control modules corresponding to at least one headlamp to control the headlamp control module of the at least one headlamp, the fault status indicating a fault in the headlamp control module of the at least one headlamp, and, based on the fault status, causing the lighting system to perform a second operation to turn on the front grille lamp and / or turn on the at least one headlamp again, including causing the lighting system to cause the first or second regional control module to control the front grille lamp control module based on the fault in the headlamp control module of the at least one headlamp to turn on a portion of the front grille lamp adjacent to the at least one headlamp. For example, using Tables 2 and 4 above as an example, assuming the at least one headlamp is the right headlamp 220, the first operation includes causing the second regional control module 252 to control the right headlamp control module 242 using the fourth communication link L4. At this time, if the fault status indicates a fault in the right headlamp control module 242, the second operation may include causing the first regional control module 251 to control the front grille lamp control module 243 using the fifth communication link L5, or causing the second regional control module 252 to control the front grille lamp control module 243 using the sixth communication link L6, so as to activate the portion 232 of the front grille lamp 230 adjacent to the right headlamp 220. The above embodiment enables the use of the front grille lamp in place of the corresponding headlamp in the event of a lamp control module failure, thereby ensuring normal vehicle travel. In the above embodiment, only the portion of the front grille lamp adjacent to at least one headlamp is activated. Alternatively, the entire front grille lamp may be activated, and the present disclosure is not limited thereto.

[0089] In some embodiments, the rated power of the first power source is greater than the rated power of the second power source. In this case, upon a failure of the headlight control module of at least one headlight (e.g., at least one of the left headlight control module and the right headlight control module), causing the lighting system to cause the first regional control module or the second regional control module to control the front grille light control module to turn on a portion of the front grille light proximate to the at least one headlight includes: upon a failure of the headlight control module of at least one headlight, causing the lighting system to cause the first regional control module to control the front grille light control module to turn on a portion of the front grille light proximate to the at least one headlight. This allows the power source with the higher rated power to be selected to power the connected regional control module to control the front grille light, thereby ensuring the brightness of the front grille light. Alternatively, if the power of the second power source is higher than that of the first power source, the second regional control module may be selected to control the front grille light control module.

[0090] In some embodiments, a first operation includes causing the first regional control module to communicate using one of the first and second communication links for controlling at least one headlamp, and a fault condition indicates a fault in the communication link for controlling the at least one headlamp. In this case, based on the fault condition, causing the lighting system to perform a second operation to activate the front grille lamps and / or reactivate the at least one headlamp may include, based on the fault in the communication link for the at least one headlamp, causing the lighting system to at least perform an operation to cause the second regional control module to communicate using one of the third and fourth communication links for the at least one headlamp, to reactivate the at least one headlamp. For example, using Tables 2 and 4 above as an example, assuming the at least one headlamp is the left headlamp 210, the first operation includes causing the first regional control module 251 to control the left headlamp control module 241 using the first communication link L1. In this case, if the fault condition indicates a fault in the first communication link L1, the second operation may include causing the second regional control module 252 to control the left headlamp control module 241 using the third communication link L3, to reactivate the left headlamp 210. In some other embodiments, the first operation includes causing the second regional control module to communicate using one of the third and fourth communication links for at least one headlamp, the fault status indicating a fault in the communication link for the at least one headlamp, and based on the fault status, causing the lighting system to perform a second operation to activate the front grille lamps and / or reactivate the at least one headlamp. This includes causing the lighting system to at least activate the first regional control module using one of the first and second communication links for the at least one headlamp to reactivate the at least one headlamp based on the fault in the communication link for the at least one headlamp. For example, using Tables 2 and 4 above as an example, assuming the at least one headlamp is the right headlamp 220, the first operation includes causing the second regional control module 252 to control the right headlamp control module 242 using the fourth communication link L4. In this case, if the fault status indicates a fault in the fourth communication link, the second operation may include causing the first regional control module 251 to control the right headlamp control module 242 using the second communication link L2 to reactivate the right headlamp 220. Additionally or alternatively, causing the lighting system to perform a second operation based on the fault state to activate the front grille lamps and / or at least one headlamp may further include: causing the lighting system to at least execute an operation of causing the first regional control module or the second regional control module to control the front grille lamp control module based on a fault in the communication link for the at least one headlamp to activate the front grille lamps (e.g., portions of the front grille lamps adjacent to the at least one headlamp). This embodiment enables the corresponding headlamp to be activated using a healthy communication link in the event of a communication link failure, thereby ensuring normal vehicle operation.

[0091] Figure 5 is a diagram illustrating a lighting system (eg, Figures 2a to 2c as well as Figure 3 Flowchart of a control method 500 for a backup area control module (i.e., an area control module used in an abnormal state in the first area control module 251 and the second area control module 252) of a lighting system 200. In some embodiments, the control method 500 may be used in a lighting system (e.g., Figures 2a to 2c as well as Figure 3 The control method 500 is executed at a regional control module (eg, the first regional control module 251 and / or the second regional control module 252) of the lighting system 200, that is, the execution subject of the control method 500 is the regional control module of the lighting system.

[0092] like Figure 5 As shown, the control method 500 may include: step 510, determining whether a lighting operation request is received, the lighting operation request including a request for turning on at least one of the two headlights; and step 520, in response to at least one headlight not being turned on, determining a fault state of the lighting system, and based on the fault state, performing a lighting turning-on operation to turn on the front grille lights and / or turn on at least one headlight again. The above embodiment can enable a backup operation to turn on the headlights again or turn on the front grille lights as a substitute or supplemental light if the lighting system fails to turn on the left and / or right headlights using the first operation.

[0093] In the above embodiment, the lighting operation request can be generated by the vehicle control device executing the control method 400 and sent to the lighting system 200. Alternatively, the lighting operation request can be generated by the user pressing or touching the headlight on button and sent to the lighting system 200.

[0094] It should be understood here that the characteristics of the lighting operation request, at least one headlamp, fault state, and the restart of at least one headlamp in the above-mentioned control method 500 are the same as the characteristics of the lighting operation request, at least one headlamp, fault state, and the restart of at least one headlamp in the control method 400. For the sake of brevity, they will not be described in detail here.

[0095] In some examples, the backup area control module may request the vehicle control device to re-enable control of at least one headlamp based on the detected fault condition. In this case, performing a light-enabling operation to enable the front grille lamp and / or at least one headlamp based on the fault condition may include: in response to receiving an indication of consent from the vehicle control device, performing the light-enabling operation to enable the front grille lamp and / or at least one headlamp based on the fault condition.

[0096] In some embodiments, when the action of turning on at least one headlamp for the first time is performed by a regional control module, the control method 500 may further include: in response to receiving a light operation request, causing the at least one headlamp to turn on. For example, the regional control module controls a light control module for controlling the at least one headlamp using a corresponding communication link to cause the headlamp to turn on.

[0097] In an embodiment where the specific actions of the light-on operation can be determined by the regional control module based on a fault condition, the fault condition indicates a power failure, a master regional control module failure, or a communication link failure with the master regional control module in the lighting system. In this case, executing the light-on operation to activate the front grille lamps and / or reactivate at least one headlamp based on the fault condition may include controlling at least one headlamp control module (i.e., one of the left and right headlamp control modules for the at least one headlamp) based on the fault condition to reactivate the at least one headlamp. For example, if the control method 500 is executed by the first regional control module, the master regional control module may be the second regional control module. After the second regional control module performs the action of activating the at least one headlamp for the first time, the first regional control module, based on a detected power failure, a second regional control module failure, or a communication link failure with the second regional control module, controls at least a lighting control module for controlling the at least one headlamp to reactivate the at least one headlamp. The above embodiment can implement a backup operation to ensure normal vehicle lighting in the event of a lighting system failure. Alternatively, executing a lighting activation operation based on a fault condition to activate the front grille lamps and / or at least one headlamp can include controlling a front grille lamp control module to activate the front grille lamps (e.g., a portion of the front grille lamps adjacent to the at least one headlamp) based on the fault condition.

[0098] In some embodiments, executing a light activation operation to activate the front grille lamps and / or at least one headlamp based on a fault condition includes: controlling the headlamp control module of the at least one headlamp based on the fault condition to activate the at least one headlamp; and controlling the front grille lamp control module to activate a portion of the front grille lamp proximate to the at least one headlamp. The above embodiment enables performing a backup operation to activate the at least one headlamp and the front grille lamps in the event of a lighting system failure to ensure proper vehicle illumination. In the above embodiment, only the portion of the front grille lamps proximate to the at least one headlamp is activated. Alternatively, the entire front grille lamp may be activated, and the present disclosure is not limited thereto.

[0099] In some embodiments, the fault condition indicates a fault in the headlight control module of at least one headlight. Based on the fault condition, executing a light activation operation to activate the front grille lights and / or reactivate the at least one headlight includes: controlling the front grille light control module to activate a portion of the front grille lights proximate to the at least one headlight based on the fault condition. The above embodiment enables execution of a backup operation to alternately activate the front grille lights in the event of a light control module failure, thereby ensuring normal vehicle lighting. In the above embodiment, only the portion of the front grille lights proximate to the at least one headlight is activated; alternatively, the entire front grille lights may be activated, and the present disclosure is not limited thereto.

[0100] Figure 6 is a schematic block diagram illustrating a control device 600 according to an exemplary embodiment. Figure 6 As shown, the control device 600 may include a first determination module 610, a first execution module 620, and a second execution module 630. The first determination module 610 is configured to determine whether to turn on at least one of the two headlights. The first execution module 620 is configured to, in response to a determination that at least one headlight is turned on, cause the lighting system to perform a first operation to turn on the at least one headlight. The second execution module 630 is configured to, in response to at least one headlight not being turned on, obtain a fault status of the lighting system and, based on the fault status, cause the lighting system to perform a second operation to turn on the front grille lights and / or turn on the at least one headlight again.

[0101] The above embodiment can enable the backup operation to turn on the headlights again or turn on the front grille lights as substitute lights or supplementary lights when the lighting system fails to turn on the left headlight and / or the right headlight using the first operation.

[0102] It should be understood that Figure 6 The modules of the apparatus 600 shown in FIG. 6 can be used in conjunction with the reference Figure 4 The steps in the method 400 described above correspond to each other. Therefore, the operations, features and advantages described above for the method 400 are also applicable to the apparatus 600 and the modules included therein. For the sake of brevity, some operations, features and advantages are not described in detail here.

[0103] Figure 7 FIG. 7 shows a schematic block diagram of a control device 700 for a backup area control module of a lighting system according to an exemplary embodiment. Figure 7As shown, the control device 700 may include a second determination module 710 and a third execution module 720. The second determination module 710 is configured to determine whether a light operation request has been received, the light operation request including a request to turn on at least one of the two headlights. The third execution module 720 is configured to determine a fault state of the lighting system in response to at least one headlight not being turned on, and based on the fault state, execute a light-on operation to turn on the front grille lights and / or at least one headlight again.
