Description

Technical Field

[0001] The present invention relates to the technical field of vehicle atmosphere light detection, and in particular to a vehicle atmosphere light node installation detection method, system and storage medium based on decoupling of ID information and position information. Background Art

[0002] With the increasing demand for personalized vehicle interiors, ambient lighting, as an important component of improving the interior environment, has become increasingly complex in design. However, during the production and assembly process, due to the similar appearance and high interchangeability of ambient lighting, installation errors often occur, resulting in the need for additional manpower for inspection and correction, which increases production costs. Traditional error-proofing measures such as wiring harness error-proofing or color coding are effective, but they add additional costs.

[0003] In the actual production process, the ambient lights of some car models are non-interchangeable, and the ambient lights of each node are easy to distinguish during the factory installation; while the ambient lights of other car models share the same light strip, and the connectors of the ambient lights are the same, which are interchangeable, and this situation is difficult to distinguish during the factory installation.

[0004] In the existing allocation methods of atmosphere lights, there are two methods: fixed addressing and automatic addressing.

[0005] Fixed addressing of ambient light means that the ambient light node assigns a preset, unchangeable fixed address to each ambient light module according to the connection sequence of the ambient light harness, and writes the node ID in advance during the manufacturing process. During the assembly process, the ambient light node is assembled according to the connection sequence of the harness. The vehicle's body controller will have corresponding software to identify and control each ambient light module. The relationship between the ambient light installation position and the ambient node in the fixed addressing method is shown in the figure below. Figure 1 shown.

[0006] However, the existing fixed addressing allocation method has the following disadvantages: the scalability of the ambient light is poor, and adding a new ambient light module may require redesigning the wiring harness and modifying the software mapping.

[0007] The automatic addressing of the atmosphere light means that the atmosphere light does not need to be written in advance during the manufacturing process. When the vehicle is offline, the atmosphere light controller allocates nodes according to the serial connection order of the atmosphere light, starting from the first Lin node close to the atmosphere light controller, and assigning IDs in sequence from near (from the controller) to far. In one automatic addressing, only the previous allocation is successful, and the subsequent child nodes can be allocated. After receiving the above configuration message, the child node will process the address configuration function of the child node in the interval field of the next message. The node with an assigned ID does not respond to the new allocation ID instruction. In this way, automatic ID allocation is achieved.

[0008] However, the disadvantage of this addressing method is that when the vehicle ambient light is installed incorrectly or erroneously during off-line assembly, the automatic addressing method cannot identify whether the ambient light is installed incorrectly or erroneously. Summary of the invention

[0009] The technical problem to be solved by the present invention is that the present invention proposes a vehicle atmosphere light node installation detection method, system and storage medium, which realizes the flexibility and accuracy of atmosphere light installation by adding atmosphere light shape feature recognition, location information feature management and ID management and other technical means, reduces the installation error rate, improves assembly efficiency, reduces production costs and improves user experience.

[0016] When it is recognized that the current atmosphere light node shape category is an interchangeable category, the corresponding allocation method is selected as the automatic addressing method.

[0020] When the allocation mode is the automatic addressing mode, an allocation ID value is automatically allocated to each atmosphere light node, and the ID quantity and allocation ID value reported by each atmosphere light node are obtained.

[0021] Wherein, judging whether the atmosphere light node is correctly installed according to the position information or ID information fed back by each atmosphere light node further includes:

[0022] When the allocation mode is a fixed addressing mode, the predetermined position ID value reported by each atmosphere light node is compared with the allocated position ID value. If there is a difference between the two, it is determined that the corresponding atmosphere light node is installed incorrectly; otherwise, it is determined that the corresponding atmosphere light node is installed correctly;

[0023] When the allocation method is automatic addressing, when the reported ID quantity and each allocated ID value are correct, it is determined that each atmosphere light node is installed correctly; when there is a missing allocated ID value, it is determined that the corresponding atmosphere light node is installed incorrectly.

[0024] Among them, further include:

[0025] When it is determined that the atmosphere light node is installed incorrectly, an alarm is issued to instruct the atmosphere light node to locate the incorrect node and replace it.

[0026] Accordingly, another aspect of the present invention further provides a vehicle atmosphere light node installation detection system, comprising:

[0027] An allocation mode identification module is used to identify the modeling category characteristics of the atmosphere light nodes, select the allocation mode of the atmosphere light nodes corresponding to the category characteristics, and determine whether to write the predetermined position information for each atmosphere light node, wherein the allocation mode is one of a fixed addressing mode and an automatic addressing mode;

[0028] The allocation processing module is used to, after the vehicle ambient light nodes are installed, adopt the selected ambient light node allocation method, allocate position information or ID information to each ambient light node, and obtain the position information or ID information fed back by each ambient light node;

[0029] The fault judgment module is used to judge whether the atmosphere light node is correctly installed according to the position information or ID information fed back by each atmosphere light node.

[0030] Wherein, the allocation mode identification module further includes:

[0036] The second allocation unit is used to automatically allocate an allocation ID value to each atmosphere light node when the allocation mode is the automatic addressing mode, and obtain the ID quantity and the allocation ID value reported by each atmosphere light node.

[0058] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0059] like Figure 2 FIG. 1 is a schematic diagram showing the main process of an embodiment of a vehicle atmosphere light node installation detection method provided by the present invention. Figures 3 to 5 As shown, in this embodiment, it is necessary to predetermine the atmosphere light node position information and ID information topology map (such as Figure 4 As shown), and during installation, the diagnostic instrument, body controller, and each ambient light node are connected in series (as shown Figure 3 shown).

[0060] More specifically, the method provided by the present invention comprises at least the following steps:

[0061] Step S10, identifying the shape category characteristics of the atmosphere light nodes, selecting an allocation method of the atmosphere light nodes corresponding to the category characteristics, and determining whether to write predetermined position information for each atmosphere light node, wherein the allocation method is one of a fixed addressing method and an automatic addressing method;

[0062] In a specific example, step S10 includes:

[0063] When it is identified that the shape category of the current atmosphere light node is a non-interchangeable category, the corresponding allocation method is selected as a fixed addressing method, and a predetermined position ID value is written for each atmosphere light node according to a predetermined wiring harness connection sequence;

[0064] When it is recognized that the current atmosphere light node shape category is an interchangeable category, the corresponding allocation method is selected as the automatic addressing method.

[0065] Specifically, these styling feature recognitions can be added during the design phase of the ambient light. These features can be small differences on the ambient light housing, such as different protrusions, grooves or markings, which can be recognized by an automatic recognition system (such as a camera or sensor).

[0066] Step S11, after the vehicle ambient light nodes are installed, the selected ambient light node allocation method is used to allocate position information or ID information to each ambient light node, and the position information or ID information fed back by each ambient light node is obtained;

[0067] In a specific example, the step S11 further includes:

[0068] The atmosphere light nodes are connected in series. Any two nodes are connected in series through the input and output ends, and the output end of the farthest node is open. For specific series connection methods, please refer to Figure 3 As shown in the figure, this serial connection mode can support both fixed addressing and automatic addressing. The body controller can realize the addressing work, and the diagnostic instrument can trigger the automatic ID allocation routine and locate the fault according to the feedback of the body controller.

[0069] When the allocation mode is a fixed addressing mode, an allocation position ID value is sequentially allocated to each atmosphere light node according to the connection sequence of each atmosphere light node; and the predetermined position ID value and the allocation position ID value reported by each atmosphere light node are obtained;

[0070] When the allocation mode is the automatic addressing mode, an allocation ID value is automatically allocated to each atmosphere light node, and the ID quantity and allocation ID value reported by each atmosphere light node are obtained.

[0071] Step S12, judging whether the atmosphere light nodes are correctly installed according to the position information or ID information fed back by each atmosphere light node.

[0072] In a specific example, the step S12 further includes:

[0073] When the allocation mode is a fixed addressing mode, the predetermined position ID value reported by each atmosphere light node is compared with the allocated position ID value. If there is a difference between the two, it is determined that the corresponding atmosphere light node is installed incorrectly; otherwise, it is determined that the corresponding atmosphere light node is installed correctly;

[0074] When the allocation method is automatic addressing, when the reported ID quantity and each allocated ID value are correct, it is determined that each atmosphere light node is installed correctly; when there is a missing allocated ID value, it is determined that the corresponding atmosphere light node is installed incorrectly.

[0075] More specifically, the method provided by the present invention further comprises:

[0076] When it is determined that the atmosphere light node is installed incorrectly, an alarm is issued to instruct the atmosphere light node to locate the incorrect node and replace it.

[0077] It is understandable that if Figure 5 As shown, the present invention provides a method for installing and detecting a vehicle ambient light node, which can solve the problem that an increased number of sub-nodes in the ambient light system and sub-nodes with similar manufacturing processes easily cause confusion during vehicle assembly and maintenance.

[0078] The specific principle is that, aiming at the problem of assembling the atmosphere lamps, a series connection method of the atmosphere lamps is proposed; according to the installation position of each atmosphere lamp, the atmosphere lamp nodes and the installation positions have a one-to-one correspondence.

[0079] Aiming at the non-interchangeability of the structure of the ambient light of different vehicle models, an ambient light offline detection method based on fixed addressing is proposed. By adding a routine for automatic ID allocation of the ambient light to the vehicle offline program, the body controller compares whether the pre-written fixed ID of each ambient light node is the same as the allocated ID to perform fault matching, and feeds back the ID matching result of each node to the diagnostic instrument. The diagnostic instrument displays the cause of the fault, and accurately locates the faulty node of the ambient light according to the cause of the fault, and performs fault troubleshooting.

[0080] In view of the interchangeability of the structure of the atmosphere light, the atmosphere lights of different models share the same light strip, etc., an automatic addressing offline detection method is proposed. The production line assigns IDs to the atmosphere lights. Automatic addressing starts from the first Lin node close to the atmosphere light controller and assigns IDs in sequence from near (from the controller) to far. In one automatic addressing, only when the previous allocation is successful can the subsequent nodes be assigned. The nodes with assigned IDs do not respond to new allocation ID instructions. When the connectors of the same light strip are plugged in, the IDs are automatically assigned and the IDs of the atmosphere light nodes are assigned according to the serial data. The number of IDs and ID information fed back by each atmosphere light node determine whether the serially connected atmosphere light nodes are faulty. This greatly simplifies the design and assembly complexity of the atmosphere light. After the same sub-nodes are assembled to different positions of the car, as long as the automatic addressing configuration is performed, the addresses corresponding to different positions can be generated, avoiding the problem of wrong installation and greatly simplifying the design and subsequent installation and maintenance work.

[0081] It is understandable that the present invention proposes an offline assembly method for atmosphere lights, which ensures the correct installation of atmosphere lights by decoupling ID information from position information. In the present invention, the position information and quantity information of the atmosphere lights are obtained through the wiring harness connection principle of the atmosphere lights, and the addressing mode (fixed addressing\automatic addressing) and addressing parameters (position parameters\ID quantity parameters) of the atmosphere lights are adjusted according to the shape characteristics of the atmosphere lights, which can meet the quantity design requirements of the atmosphere lights and the convenience of their production, installation and maintenance.

[0082] In an embodiment of the present invention, by adding the recognition of the styling features of the atmosphere lights, the allocation methods of the atmosphere lights are classified and processed based on the styling features of the atmosphere lights. Taking the styling features of the atmosphere lights as the precondition, automatic addressing or fixed addressing is selected to achieve decoupling of the position information and ID information. By decoupling the position information from the ID information, it is possible to independently verify whether the actual position of each atmosphere light meets expectations. Even if the position information changes, the system can maintain the consistency of the ID through an intelligent algorithm to ensure the decoupling of the ID and position information. If the atmosphere light needs to be replaced, the system can automatically update the ID information and verify whether the new ID is installed correctly. At the same time, the system retains the historical records of each atmosphere light ID, including installation time, position changes and other information, which is helpful for troubleshooting and maintenance.

[0083] By adding the feature management of the ambient light position information, before the ambient light is installed, the expected installation position is defined for each ambient light according to the position and the connection sequence of the wiring harness, and the position information of the ambient light is managed.

[0084] Perform atmosphere light ID management based on the allocation method of atmosphere lights: Before the atmosphere lights are installed, the system automatically assigns a unique ID to each light and records its expected installation location.

[0085] In the present invention, ID verification and position verification can be implemented. The ID verification means that during the installation process, the reader reads the ID of the atmosphere light and verifies whether it is consistent with the preset ID information. The position verification means that the reader reads the position information of the atmosphere light and compares it with the preset installation position. If the position information does not match the expectation, the system issues a warning.

[0086] At the same time, it can be understood that the method provided by the present invention, 除了氛围灯 ， 可以应用于其他场景 ， 例如 It can be applied to seat controllers, window controllers, and rear armrest screens. The window controller can be assigned by writing IDs and troubleshooted by automatic addressing; while the controllers of the rear armrest screen are different on the left and right, and can be troubleshooted by fixed addressing.

[0087] In order to further understand the essence of the present invention, the following Figure 6 and Figure 7 The specific examples shown are used to illustrate the process of fixed addressing and automatic addressing in the method of the present invention.

[0088] like Figure 6 As shown, the fixed addressing method in this embodiment specifically includes the following steps:

[0089] First, according to Figure 4 The position ID information is obtained from the topological diagram of the atmosphere light position information and ID information shown in the figure. According to the serial connection sequence of the wiring harness, the position ID information of each atmosphere light node is written in advance during the atmosphere light production process.

[0090] In press Figure 3 After installing the ambient light controller and all the ambient light nodes in the order, the diagnostic instrument sends a diagnostic message to the body controller to request a position ID match and compare whether the pre-written position ID of each ambient light node is the same as the assigned ID;

[0091] After receiving the request, the body controller detects whether the current environment (such as system voltage, LIN bus) meets the conditions for assigning an ID. If the conditions are met, the controller replies that the diagnostic instrument has successfully started this routine and sends the instruction to assign an ID to each node through the LIN bus. If the conditions are not met, the controller replies that the diagnostic instrument did not start this routine.

[0092] Each node of the atmosphere light receives the position ID instruction to allocate the position ID and responds to the allocation result;

[0093] The body controller inquires about the allocation results of each node to determine whether the ID quantity and position ID allocation relationship match. The body controller determines whether the position ID is consistent with the allocation ID, and then feeds back the ID allocation result to the diagnostic instrument;

[0094] The diagnostic instrument obtains the result of the controller's automatic ID assignment. If the match is inconsistent, the failure cause will be recorded and displayed. According to the failure cause, the faulty node will be located and the installation of the atmosphere light faulty node will be checked.

[0095] For example, in one example, suppose a vehicle has 4 ambient light nodes, which are installed in 4 different locations in the vehicle. Each node has been written with a corresponding location ID (such as 1, 2, 3, 4) when it leaves the factory.

[0096] according to Figure 4 From the content of , we know that node 1 should be installed in position A, node 2 should be installed in position B, and so on. During the production process, node 1 is written with position ID 1, node 2 is written with position ID 2, and so on.

[0097] After installing the ambient light controller and all nodes, the diagnostic tool sends a request to the body controller to match the location ID with the assigned ID.

[0098] After the body controller detects that the environment meets the conditions, it starts to send instructions to assign IDs to each node through the LIN bus. Since the node has a pre-written location ID, this process is actually verifying whether the node is installed in the correct location.

[0099] Assume that node 1 and node 2 are correctly installed in position A and position B, but node 3 is incorrectly installed in position D, and node 4 is installed in position C. The body controller will feed back this information to the diagnostic instrument.

[0100] After receiving the feedback, the diagnostic instrument found that the location ID and the allocation ID of node 3 and node 4 did not match. Based on this information, the technician can locate the installation error of node 3 and node 4 and make corrections.

[0101] In this way, the solution can ensure that the ambient light node is installed and working correctly, avoiding failures caused by installation errors. At the same time, through the fault diagnosis function of the diagnostic instrument, technicians can quickly locate and solve the problem.

[0102] In this solution, each ambient light node has a pre-written fixed position ID and a subsequently assigned allocation ID. The two IDs are matched to ensure that the ambient light node is correctly installed and working.

[0103] like Figure 7 As shown, the automatic addressing method in this embodiment specifically includes the following steps:

[0104] First, according to Figure 4 Establish the topology map of the atmosphere light location information and ID information to obtain the ID quantity information;

[0105] In press Figure 3 After installing the atmosphere light controller and all the atmosphere light nodes in the order, and ensuring that all the nodes are connected in series through the LIN bus. The diagnostic instrument sends a request to the atmosphere light controller for the automatic ID allocation routine to allocate the atmosphere light ID for the first time;

[0106] After receiving the request, the body controller detects whether the current environment (such as system voltage, LIN bus) meets the conditions for assigning IDs. If the conditions are met, the controller replies that the diagnostic instrument has successfully started this routine, and sends the instruction for assigning IDs to each node through the LIN bus; if the conditions are not met, the controller replies why the diagnostic instrument did not start this routine;

[0107] The nodes of the atmosphere automatically allocate IDs according to the instructions of the body controller, and allocate IDs in order from near to far (from the controller). Nodes that have been allocated IDs will not respond to new allocation ID instructions to ensure that each node is allocated a unique ID; and reply with the allocation result. The body controller asks each node for the allocation result, and checks whether the number of IDs fed back and the allocation result of the allocated ID match the previously determined relationship between the number of IDs and the position ID allocation;

[0108] The diagnostic instrument requests the result of the controller's automatic ID assignment. If the match is inconsistent, the failure cause will be recorded and displayed. According to the failure cause, the faulty node will be located for inspection or replacement.

[0109] In a specific example, assuming that the ambient light system of a vehicle model contains 5 nodes, according to the automatic addressing method, these nodes should be assigned IDs 1, 2, 3, 4, and 5 in sequence. After the installation is completed, the diagnostic instrument requests automatic ID allocation and receives feedback from the body controller.

[0110] Assume that the feedback received by the diagnostic instrument is ID 1, 2, 3, 5, and ID 4 is missing.

[0111] This indicates that during the ID allocation process, node 4 did not respond to the allocation instruction correctly or there were other faults.

[0112] In the process of determining the cause of the fault, you can first check whether the connection of node 4 is correct, including whether the line connection and the socket are firm, etc. If the connection is normal, try to re-execute the automatic ID allocation process to see whether a complete ID allocation result can be obtained.

[0113] If ID 4 still cannot be obtained, it may be that node 4 itself has a fault and cannot correctly receive or respond to the instruction to allocate the ID.

[0114] Based on the above inspection results, it can be determined that the faulty node is node 4. If node 4 is interchangeable, you can try to swap it with another node that is working properly to verify whether it is a problem with the node itself. If the problem still exists after the swap, then the problem may be in the installation location of node 4 or the lines related to it; if the problem is transferred to another node, then the original node 4 is indeed a faulty node.

[0115] According to the cause of the fault, take appropriate measures to repair or replace the faulty node. If it is a problem with the node itself, you need to replace it with a new node; if it is a problem with the installation location or line, you need to repair the related fault.

[0116] In summary, this solution can realize automatic ID allocation for the atmosphere light nodes and quickly locate the faulty nodes and fault causes when there is a mismatch, which greatly improves the assembly efficiency and reliability of the atmosphere light system.

[0117] like Figure 8 FIG. 1 is a schematic diagram showing a structure of an embodiment of a vehicle atmosphere light node installation detection system provided by the present invention; and FIG. Figure 10 to Figure 11 As shown, in this embodiment, the vehicle atmosphere light node installation detection system 1 at least includes:

[0118] The allocation mode identification module 10 is used to identify the modeling category characteristics of the atmosphere light nodes, select the allocation mode of the atmosphere light nodes corresponding to the category characteristics, and determine whether to write the predetermined position information for each atmosphere light node, wherein the allocation mode is one of a fixed addressing mode and an automatic addressing mode;

[0119] The allocation processing module 11 is used to allocate the selected atmosphere light node after the vehicle atmosphere light node is installed, allocate position information or ID information to each atmosphere light node, and obtain the position information or ID information fed back by each atmosphere light node;

[0120] The fault judgment module 12 is used to judge whether the atmosphere light node is correctly installed according to the position information or ID information fed back by each atmosphere light node;

[0121] The fault indication unit 12 is used to issue an alarm indication when it is determined that the atmosphere light node is installed incorrectly, and instruct to locate the incorrect node of the atmosphere light node and perform a replacement process.

[0122] like Fig. 9 As shown, in a specific example, the allocation mode identification module 10 further includes:

[0123] The first identification unit 100 is used to, when identifying that the shape category of the current atmosphere light node is a non-interchangeable category, select the corresponding allocation mode as a fixed addressing mode, and write a predetermined position ID value for each atmosphere light node according to a predetermined wiring harness connection sequence;

[0124] The second identification unit 101 is used to select the corresponding allocation method as the automatic addressing method when identifying that the current atmosphere light node modeling category is an interchangeable category.

[0125] like Fig.10 As shown, in a specific example, the allocation processing module 11 further includes:

[0126] A processing unit 110 is installed to connect the atmosphere light nodes in series, where any two nodes are connected in series through the input and output ends, and the output end of the farthest node is open;

[0127] The first allocation unit 111 is used to allocate an allocation position ID value to each atmosphere light node in sequence according to the connection sequence of each atmosphere light node when the allocation mode is a fixed addressing mode; and obtain the predetermined position ID value and the allocation position ID value reported by each atmosphere light node;

[0128] The second allocation unit 112 is used to automatically allocate an allocation ID value to each atmosphere light node when the allocation mode is the automatic addressing mode, and obtain the ID quantity and the allocation ID value reported by each atmosphere light node.

[0134] Implementing the embodiments of the present invention has the following beneficial effects:

[0135] The present invention proposes a vehicle atmosphere lamp installation detection method, system and storage medium. By taking the shape characteristics of the atmosphere lamp as a precondition, automatic addressing or fixed addressing is selected to achieve decoupling of position information and ID information. During the atmosphere lamp assembly process, the diagnostic instrument can be used to analyze whether the assembly result is correct. When an error occurs in the assembly, the node assembly status is provided to facilitate the location of the error node, thereby improving the efficiency of assembly and troubleshooting to meet the convenience of its production, installation and maintenance.

[0136] The present invention implements the flexibility and accuracy of installing the atmosphere light by adding technical means such as the recognition of the shape features of the atmosphere light, the management of the location information features, and the ID management. The production cost can be reduced because no additional wiring harness error prevention or color coding is required. The assembly efficiency is improved, and rework caused by installation errors can be avoided. The effect of the atmosphere light is ensured to meet the design requirements, and the user experience is improved. This can solve the problem that the number of sub-nodes in the current atmosphere light system and the sub-nodes with similar manufacturing processes are prone to cause confusion during vehicle assembly and maintenance.
