Description

Technical Field

[0001] This invention relates to the field of commercial vehicle development technology, specifically to a method, apparatus, equipment, and storage medium for determining the production launch time of a vehicle model. Background Technology

[0002] In the vehicle development process, the Bill of Materials (BOM) is the core data guiding production. It records the complete composition of the product in a structured form, including the names, quantities, and hierarchical relationships of raw materials, parts, and semi-finished products, spanning the entire lifecycle from design and process to manufacturing. The R&D department issues BOM information to the manufacturing department in units of notifications. The manufacturing department uses the notification as the smallest management unit for production preparation, and marks the notification as ready for production once all parts within the entire notification have met the production conditions. The latest production start time for all notifications related to a particular vehicle model is the production start time for that model.

[0003] Using the design notification as the basis for determining the production start date presents the following technical problems, such as... Figure 1 As shown, there are four design notifications: DE1, DE2, DE3, and DE4. DE1 releases five parts, applied to three different vehicle models: V1, V2, and V3. The production preparation time varies for each part; the production start time for this notification is calculated based on the longest part, T5. Even if part A1 has completed supplier selection and mold preparation by time T2, it still needs to wait until time T5 to be upgraded to the production stage and implemented in actual vehicle production. Simultaneously, the production start time for the V1 model, which is related to notification DE1, also has to wait until time T5. Furthermore, from... Figure 1 It can be seen that there is a matching relationship between DE1 and DE3. DE3 released part G1, which is unrelated to V1. G1 caused a matching relationship to be created between the two notifications, DE3 and DE4, resulting in a multi-layered matching system. Although all parts for V1 can be ready for production by time T4, the existence of this multi-layered matching system forces the production launch of the V1 model to be delayed until time T6. As time progresses, the multi-layered matching system may become increasingly longer, leading to even later production launches for the V1 model.

[0004] In summary, current solutions operate on a per-design-notification basis, meaning that even if a part in the design notation is unrelated to the target vehicle model, production must wait until that part is ready. Furthermore, when there are matching parts between design notations, this further exacerbates the delay in vehicle production time. There is an urgent need to provide a method, apparatus, equipment, and storage medium for determining vehicle production time, capable of decoupling from design notations to shorten the vehicle production time. Summary of the Invention

[0005] In view of this, it is necessary to provide a method, apparatus, equipment and storage medium for determining the production time of a vehicle model, so as to solve the technical problem that the determination of the production time of a vehicle model is based on the design notification as the smallest unit in the prior art, which leads to the delay of the production time of the vehicle model.

[0006] To address the aforementioned technical problems, in a first aspect, the present invention provides a method for determining the production launch time of a vehicle model, comprising: Obtain multiple design notifications, each of which includes a parts list, parts interface information, the vehicle model to which the parts belong, and the relationship between the design notifications; Based on the target vehicle model and the vehicle model to which the parts belong, an initial set of parts is determined from the multiple design notifications; Based on the aforementioned matching relationship, determine the pairs of parts to be verified in the initial parts set; Based on the component interface information, verify whether there is a physical interface relationship between the two components in the component pair to be verified; If no physical interface relationship exists, the matching relationship between the part to be verified and the target vehicle model is terminated, and a list of valid parts matching relationships for the target vehicle model is obtained. The production time of the target vehicle model is determined based on the list of effective parts matching relationships.

[0007] In one possible implementation, determining the production time of the target vehicle model based on the effective parts matching list includes: Determine the production time of each valid part in the list of valid parts matching relationships; The latest production time among the production times of the parts shall be taken as the production time of the target vehicle model.

[0008] In one possible implementation, determining the production time of each valid part in the valid parts matching relationship list includes: Determine whether the valid part has an actual production launch time; When the effective part has an actual production time, the production time of the part is determined based on the actual production time. When the effective part does not have an actual production time, the production time of the effective part is predicted based on historical parts with actual production times, and the production time of the part is obtained.

[0009] In one possible implementation, predicting the production time of the effective part based on historical parts with existing actual production times, to obtain the production time of the part, includes: Obtain the part feature parameters of valid parts and the historical feature parameters of each historical part; The similarity between the valid part and the historical part is determined based on the part feature parameters and the historical feature parameters; Based on the similarity, multiple target historical parts are identified among the historical parts, and the average of the actual production time corresponding to the multiple target historical parts is taken as the production time of the part.

[0010] In one possible implementation, both the part feature parameters and the historical feature parameters include part function, part characteristics, part weight, part material, and part size.

[0011] In one possible implementation, the method further includes: Obtain the actual target production time of the target vehicle model, and adjust the number of the multiple target historical parts based on the actual target production time, and / or the weight of the part feature parameters in the similarity calculation process.

[0012] In one possible implementation, before determining the production time of the target vehicle model based on the effective parts matching list, the following method is further included: Send the effective parts matching relationship to the designers; In response to the designer's feedback on the effective parts matching relationships, the effective parts matching relationship list is revised to obtain an optimized parts matching relationship list.

[0013] Secondly, the present invention also provides a device for determining the production time of a vehicle model, comprising: The design notification acquisition unit is used to acquire multiple design notifications, each of which includes a parts list, parts interface information, the vehicle model to which the parts belong, and the matching relationship between the design notification and the parts. An initial parts set determination unit is used to determine an initial parts set from the plurality of design notifications based on the target vehicle model and the vehicle model to which the parts belong; The part pair to be checked determination unit is used to determine the part pairs to be checked in the initial part set based on the matching relationship; An interface verification unit is used to verify, based on the part interface information, whether there is a physical interface relationship between the two parts in the pair of parts to be verified. The relationship decoupling unit is used to decouple the matching relationship of the part to be verified under the target vehicle model when there is no physical interface relationship, so as to obtain a list of valid part matching relationships for the target vehicle model. The production time analysis unit is used to determine the production time of the target vehicle model based on the effective parts matching relationship list.

[0014] Thirdly, the present invention also provides a vehicle production preparation device, including a memory and a processor, wherein, The memory is used to store programs; The processor, coupled to the memory, is used to execute the program stored in the memory to implement the steps in the method for determining the vehicle production time in any of the above possible implementations.

[0015] Fourthly, the present invention also provides a computer-readable storage medium for storing a computer-readable program or instructions, which, when executed by a processor, can implement the steps in the method for determining the vehicle production time described in any of the above possible implementations.

[0016] The beneficial effects of the present invention are as follows: The method for determining the production time of a vehicle model provided by the present invention takes the target vehicle model as the smallest unit, verifies the physical interface relationship through the part interface information, accurately identifies and eliminates invalid matching relationships under the target vehicle model, cuts off the trailing effect and multi-layer matching relationships formed by irrelevant parts, so that the production time of the target vehicle model depends only on its truly necessary parts, rather than the entire design notification, and can advance the production time of the vehicle model by several production preparation cycles.

[0017] At the same time, by eliminating ineffective supply chains, the manufacturing department no longer needs to prepare for the production of parts for unrelated models in advance, such as supplier selection and mold development. Resources can be focused on the parts truly needed for the target model, avoiding unnecessary resource investment and occupation, reducing early production pressure on suppliers, and lowering the company's inventory and capital costs.

[0018] Furthermore, in the traditional model, changes to a single vehicle model are subject to a general notification. This invention allows each vehicle model to manage its production process based on its effective parts matching list. When conducting personalized design, configuration upgrades, or rapid iterations, new or modified models can be launched independently and flexibly without being constrained by existing or other models, greatly enhancing the company's ability to respond to market changes.

[0019] In summary, this invention achieves a leap from extensive management to intensive management, effectively solving the industry pain point of long vehicle production cycles in complex configuration environments in fields such as commercial vehicles, and bringing comprehensive positive effects.

Detailed Implementation

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] It should be understood that the schematic drawings are not drawn to scale. The flowcharts used in this invention illustrate operations implemented according to some embodiments of the invention. It should be understood that the operations in the flowcharts may be implemented out of order, and steps without logical contextual relationships may be reversed or performed simultaneously. Furthermore, those skilled in the art, guided by the content of this invention, may add one or more other operations to the flowcharts, or remove one or more operations from the flowcharts. Some block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities may be implemented in software, in one or more hardware modules or integrated circuits, or in different network and / or processor devices and / or microcontroller devices.

[0024] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0025] This invention provides a method, apparatus, equipment, and storage medium for determining the production time of a vehicle model, which will be described below.

[0026] Figure 2 A schematic flowchart of an embodiment of the method for determining the production time of a vehicle model provided by the present invention is shown below. Figure 2 As shown, the methods for determining the production time of a vehicle model include: S201. Obtain multiple design notices, each of which includes a parts list, parts interface information, the vehicle model to which the parts belong, and the compatibility between the design notices.

[0027] like Figure 1 As shown, there are four design notices: DE1, DE2, DE3 and DE4. Each design notice includes a parts list consisting of multiple parts. For example, DE1 includes five parts: A1, A2, B1, B2 and C1; DE2 includes three parts: D1, D2 and E1; DE3 includes three parts: F1, F2 and G1; and DE4 includes two parts: H1 and J1.

[0028] Component interface information refers to whether there is an interface association between two components, which can be determined by the interface code in the design specification. For example, if the interface code of component A1 is AD-001 and the interface code of component D1 is DA-001, it means that there is an interface between component A1 and component D1.

[0029] The vehicle model to which a part belongs is used to indicate which vehicle model a particular part belongs to. The vehicle model column in the design notification is used to represent this information.

[0030] The relationships between design notices can be directly determined through the list of supporting notices within the design notice, such as... Figure 1 DE1 is paired with DE2 and DE3, meaning that DE1 has a pairing relationship with DE2 and DE3.

[0031] S202. Based on the target vehicle model and the vehicle model to which the parts belong, determine the initial parts set from multiple design notifications.

[0032] Specifically, parts whose vehicle model is the same as the target vehicle model are identified as parts in the initial parts set. For example, such as Figure 1 As shown, if the target vehicle model is V1, the initial parts set consists of A1, A2, B1, C1, D1, D2, F1, and F2.

[0033] S203. Determine the pairs of parts to be verified in the initial parts set based on the matching relationship.

[0034] Since DE1, DE2, and DE3 all have a pairing relationship, the initial parts set includes A1, A2, B1, and C1 from DE1, D1 and D2 from DE2, and F1 and F2 from DE3. Therefore, each part in DE1 and each part in DE2, as well as each part in DE1 and each part in DE3, constitute a pair of parts to be inspected.

[0035] S204. Verify whether there is a physical interface relationship between the two parts in the part pair to be verified based on the part interface information.

[0036] Specifically, in Figure 1 Based on the data in the middle, the parts pairs to be verified between DE1 and DE2 include: (A1, D1): The interface code AD-001 of A1 matches the interface code DA-001 of D1, so there is indeed a physical interface relationship between the two.

[0037] (A1, D2): The interface code AD-001 of A1 does not match the interface code DA-002 of D2, therefore there is no physical interface relationship between the two.

[0038] (A2, D1): The interface code AD-002 of A2 does not match the interface code DA-001 of D1, therefore there is no physical interface relationship between the two.

[0039] (A2, D2): The interface code AD-002 of A2 matches the interface code DA-002 of D2, therefore there is a physical interface relationship between the two.

[0040] (B1, D1): The interface code BF-001 of B1 does not match the interface code DA-001 of D1, therefore there is no physical interface relationship between the two.

[0041] (B1, D2): The interface code BF-001 of B1 does not match the interface code DA-002 of D2, therefore there is no physical interface relationship between the two.

[0042] (C1, D1): C1 has no interface encoding and has no interface relationship with D1.

[0043] (C1, D2): C1 has no interface encoding and has no interface relationship with D2.

[0044] The pair of parts to be verified between DE1 and DE3 includes: (A1, F1): The interface code AD-001 of A1 does not match the interface code FB-001 of F1, therefore there is no physical interface relationship between the two.

[0045] (A1, F2): The interface code AD-001 of A1 does not match the interface code FB-002 of F2, therefore there is no physical interface relationship between the two.

[0046] (A2, F1): The interface code AD-002 of A2 does not match the interface code FB-001 of F1, therefore there is no physical interface relationship between the two.

[0047] (A2, F2): The interface code AD-002 of A2 does not match the interface code FB-002 of F2, therefore there is no physical interface relationship between the two.

[0048] (B1, F1): The interface code BF-001 of B1 matches the interface code FB-001 of F1, therefore there is a physical interface relationship between the two.

[0049] (B1, F2): The interface code BF-001 of B1 does not match the interface code FB-002 of F2, therefore there is no physical interface relationship between the two.

[0050] (B2, F2): The interface code BF-002 of B2 matches the interface code FB-002 of F2, therefore there is a physical interface relationship between the two.

[0051] (B2, F1): The interface code BF-002 of B2 does not match the interface code FB-001 of F2, therefore there is no physical interface relationship between the two.

[0052] (C1, F1): C1 has no interface encoding and has no interface relationship with F1.

[0053] (C1, F2): C1 has no interface encoding and has no interface relationship with F2.

[0054] Based on the above analysis, the part pairs with physical interface relationships are: (A1, D1), (A2, D2), (B1, F1), and (B1, F2).

[0055] S205. If no physical interface relationship exists, the matching relationship between the parts to be verified and the target vehicle model is removed, and a list of valid parts matching relationships for the target vehicle model is obtained.

[0056] Soon Figure 1 The pairing relationships between all parts except (A1, D1), (A2, D2), (B1, F1), and (B1, F2) are terminated.

[0057] S206. Determine the production time of the target model based on the list of effective parts matching relationships.

[0058] It should be noted that the production time in step S206 refers to the latest production time among all valid parts in the list of valid parts matching relationships.

[0059] Therefore, in a specific embodiment of the present invention, step S20 specifically involves: determining the production time of each valid part in the list of valid parts matching relationships; and taking the latest production time among the production times as the production time of the target vehicle model.

[0060] by Figure 1 For example, when the target vehicle model is V1, the parts associated with V1 are A1, A2, B1, C1, D1, D2, F1, and F2. The production times for these parts are T2, T2, T1, T1, T3, T3, T4, and T4, respectively. Therefore, the production time for the target vehicle model is T4.

[0061] If production is carried out using the design notification as the smallest unit, the process for determining the production time of the target model V1 is as follows: Step 1: Determine the production start time for each design notification: The production start time for each design notification is determined by the latest part within it. DE1 production start time = T5, DE2 production start time = T5, DE3 production start time = T5, DE4 production start time = T6.

[0062] The second step is to handle the matching relationships: DE1 and DE3 are matched and must be put into production simultaneously. That is, take the maximum value between DE1 and DE3, which is T5.

[0063] DE3 is paired with DE4, so DE3 must wait for DE4 before it can be put into production. Therefore, the actual production time of DE3 is delayed by DE4 until T6.

[0064] Furthermore, since DE1 is paired with DE3, the production time of DE1 was also delayed until T6.

[0065] Similarly, DE2 is paired with DE1, so the actual production time of DE2 was also delayed until T6.

[0066] In summary, the method proposed in this embodiment of the invention allows for the production time of the target vehicle model V1 to be T4, while the traditional method requires the production time of the target vehicle model V1 to be T6. Therefore, it can be seen that the method proposed in this embodiment of the invention shortens the production cycle.

[0067] It should be understood that the vehicle model production time determination method in this embodiment of the invention can be implemented in any device based on the vehicle model production time determination method, such as vehicle production equipment or vehicle production management equipment. Specifically, the vehicle model production time determination method is stored in the aforementioned device as a pre-programmed program. When the device is started, the program is invoked, and the vehicle model production time determination method is implemented.

[0068] Compared with the prior art, the method for determining the production time of a vehicle model provided in this embodiment of the invention takes the target vehicle model as the smallest unit, verifies the physical interface relationship through the part interface information, accurately identifies and eliminates invalid matching relationships under the target vehicle model, cuts off the trailing effect and multi-layer matching relationships formed by irrelevant parts, so that the production time of the target vehicle model depends only on its truly necessary parts, rather than the entire design notification, and can advance the vehicle model production time by several production preparation cycles.

[0069] At the same time, by eliminating ineffective supply chains, the manufacturing department no longer needs to prepare for the production of parts for unrelated models in advance, such as supplier selection and mold development. Resources can be focused on the parts truly needed for the target model, avoiding unnecessary resource investment and occupation, reducing early production pressure on suppliers, and lowering the company's inventory and capital costs.

[0070] Furthermore, in the traditional model, changes to a single vehicle model are subject to a general notification. This invention allows each vehicle model to manage its production process based on its effective parts matching list. When performing personalized design, configuration upgrades, or rapid iterations, new or modified models can be launched independently and flexibly without being constrained by existing or other models, greatly enhancing the company's ability to respond to market changes.

[0071] In summary, the embodiments of the present invention have achieved a leap from extensive management to intensive management, effectively solving the industry pain point of long vehicle production cycles in complex configuration environments in fields such as commercial vehicles, and bringing comprehensive positive effects.

[0072] As described above, the production time of the target model is determined by the latest time among the effective parts associated with the target model. That is, the production time of each effective part must be determined before the production time of the target model can be determined.

[0073] When a part is a mature component, its production launch time is known. However, when a part is a brand new component or involves design changes, its production launch time is unknown. To accurately determine the production launch time of valid parts in both cases, ensuring the production launch time of the target vehicle model can be determined, in some embodiments of the present invention, such as... Figure 3 As shown, the production launch time for each valid part in the valid parts matching list is determined, including: S301. Determine whether a valid part has an actual production start time; S302. When there is an actual production time for a valid part, the production time of the part shall be determined based on the actual production time. S303. When there is no actual production time for the effective part, the production time of the effective part is predicted based on the historical parts with actual production time, and the production time of the part is obtained.

[0074] This invention, by allowing prediction of the production time of valid parts based on historical parts with existing production times even when no actual production time exists, increases the means of handling data gaps. Simultaneously, it can provide relatively accurate production times in the early stages of development, reducing capacity waste or lost market opportunities due to inaccurate planning.

[0075] It should be noted that, in addition to relying on historical parts to predict the production time of effective parts, step S303 can also directly call a pre-trained production time prediction AI model when executing S303. The part feature parameters of the effective parts are input into the production time prediction AI model to obtain the part production time. The production time prediction AI model can be trained based on historical parts.

[0076] In some embodiments of the present invention, such as Figure 4 As shown, step S303 includes: S401. Obtain the part feature parameters of valid parts and the historical feature parameters of each historical part.

[0077] Specifically, the part feature parameters and the historical feature parameters include, but are not limited to, part function, part characteristics, part weight, part material, and part size.

[0078] S402. Determine the similarity between valid parts and historical parts based on part feature parameters and historical feature parameters.

[0079] Specifically, the component similarity of the part feature parameters and historical feature parameters in the dimensions of part function, part characteristics, part weight, part material and part size is calculated separately, and the component similarity is weighted to obtain the similarity score.

[0080] Among them, the component similarity of each dimension can be calculated based on the cosine similarity calculation formula.

[0081] S403. Based on similarity, identify multiple target historical parts among the historical parts, and take the average of the actual production time corresponding to the multiple target historical parts as the production time of the parts.

[0082] Specifically, the process for determining the target historical part is as follows: At least one similar historical part with a similarity greater than a preset similarity is identified, and this similar historical part is selected as the target historical part. If no historical part with a similarity greater than the preset similarity exists, a preset number of candidate historical parts with the highest similarity values ​​are identified, and these candidate historical parts are selected as the target historical part.

[0083] For example, there are five historical parts: L1, L2, L3, L4, and L5, with similarities of 50%, 60%, 80%, 70%, and 50% to the valid part Y, respectively. When the preset similarity is 65%, L3 and L4 are the target historical parts, and the production time of the part is the average of the actual production times of L3 and L4. When the preset similarity is 85%, there are no target historical parts. If the preset number is 3, then L2, L3, and L4 are selected as candidate historical parts, and the average of the actual production times of L2, L3, and L4 is used as the production time of the part.

[0084] This invention improves the accuracy of similarity by determining similarity through parameters across multiple dimensions. Furthermore, using the average of the actual production times corresponding to multiple target historical parts as the part production time enhances the accuracy and rationality of the determined part production time.

[0085] When the similarity between all historical parts and valid parts is too low, the production time determined based on historical parts is inaccurate, which in turn leads to an inaccurate production time for the target vehicle model. To overcome this technical problem, in some embodiments of the present invention, the method for determining the vehicle model production time further includes: Obtain the actual target production time of the target vehicle model, and adjust the number of multiple target historical parts based on the actual target production time, and / or the weight of part feature parameters in the similarity calculation process.

[0086] This invention adjusts the parameters used in determining the production time of the target vehicle by obtaining the actual target production time of the target vehicle, thereby improving the adaptability of the parameters to the actual scenario and thus improving the accuracy of predicting the production time of the next target vehicle.

[0087] It should be understood that the accuracy of the production start-up time depends on the accuracy of the effective parts matching list. To further ensure the accuracy of the effective parts matching list, in some embodiments of the present invention, before step S206, the following steps are also included: Send the valid parts matching relationships to the designers; In response to feedback from designers regarding effective part matching relationships, the list of effective part matching relationships is revised to obtain an optimized list of part matching relationships.

[0088] In the process of determining the parts matching list, the introduction of human correction can avoid the removal of incorrect matching relationships, further improving the accuracy of the determined optimized parts matching list, and thus improving the accuracy of the target vehicle production time.

[0089] In a specific embodiment of the present invention, a certain gas-powered vehicle H01 needs to be changed from using a 1500L gas cylinder to using two 1000L gas cylinders. In response to this requirement, the three design departments issued three design notices to modify the design, as detailed in Table 1: Table 1. List of H01 Switching 2×1000L Gas Cylinder Configuration Design Notification

[0090] According to the traditional technical solution, the production time of model H01 in Table 1 is the latest of the three design notices, namely 2025 / 12 / 31.

[0091] According to the method proposed in this embodiment of the invention, firstly, an initial set of parts related to model H01 is extracted from multiple design notices, and the results are summarized in Table 2: Table 2 Initial parts set for vehicle model H01

[0092] It should be noted that although 3728005-H01 does not belong to H01, their interface relationship exists. 3728005-H01 affects the installation of 3724950-H01, therefore, it was also added to the initial parts set.

[0093] Therefore, as shown in Table 2, the initial parts set includes a total of 6 parts, among which the effective matching relationships are: 2801144-H01 (interface: 2801144-1140021-001) and 1140021-H01 (interface: 1140021-2801144-001); 2801144-H01 (interface: 2801144-3724950-001) and 3724950-H01 (interface: 3724950-2801144-001); 1140021-H01 (interface: 1140021-1141A10-001) and 1141A10-H01 (interface: 1141A10-1140021-001); 3724950-H01 (interface: 3724950-3728005-001) and 3728005-H01 (interface: 3728005-3724950-001).

[0094] The production time of these six valid parts was then obtained or determined, and the statistical results are shown in Table 3: Table 3 Statistical Results of Production Start-up Time

[0095] As shown in Table 3, based on the method proposed in this embodiment of the invention, the production time of the target model H01 is 2025 / 10 / 30, which is significantly shorter than the 2025 / 12 / 31 determined by the traditional method.

[0096] In summary, the vehicle production time determination method proposed in this invention can effectively shorten the production time of a single vehicle model and improve work efficiency when the model undergoes design changes or upgrades. When the design change only involves a single vehicle model, production can be switched independently without waiting for unrelated models to be ready, shortening the overall project cycle by 10%–30%. That is, by using vehicle model + parts as the management granularity, the trailing effect caused by common parts and unrelated supporting relationships is eliminated.

[0097] On the other hand, embodiments of the present invention also provide a device for determining the production time of a vehicle model, such as...

The part pair determination unit 503 is used to determine the part pairs to be verified in the initial part set based on the matching relationship. The interface verification unit 504 is used to verify whether there is a physical interface relationship between two parts in the part pair to be verified based on the part interface information. The relationship decoupling unit 505 is used to decouple the matching relationship of the part to be verified under the target vehicle model when there is no physical interface relationship, so as to obtain the list of valid part matching relationships of the target vehicle model. The production time analysis unit 506 is used to determine the production time of the target vehicle model based on the effective parts matching relationship list.
