Description

Technical Field

[0001] The present invention relates to the technical field of automobile function configuration, and more specifically, to a system and method for automatically calculating, generating and switching whole vehicle configuration codes. Background Art

[0002] The configuration table is developed by the product design team based on market demand, technical specifications and regulatory requirements. It contains all possible configuration options for the vehicle, such as engine type, transmission system, interior selection, electronic equipment, functional configuration, etc. The calculation of the configuration code is a process based on logical rules, which define how different configurations affect the vehicle's electronic control unit and other system functional modules. At present, the configuration code of passenger cars is manually calculated based on the configuration table and product design logic specifications, and then manually maintained in the electrical inspection equipment, and written into the vehicle by the electrical inspection equipment to realize the various derived functional configurations of the vehicle. However, the configuration code calculation is large and covers a wide range. Manual calculation is prone to errors. Moreover, if the configuration is adjusted, it is easy to make mistakes in understanding the configuration table when calculating again, which leads to errors in the generation of configuration codes and insufficient generation efficiency.

[0003] The reasons for the above problems and defects are:

[0004] (1) Technical experience: Since the configuration code is closely related to the logic of each functional node controller, different development engineers may not be able to fully consider all possible configuration combinations and their interactions.

[0005] (2) Manual calculation and maintenance: Configuration codes are displayed in hexadecimal characters, which are numerous and long, and can easily lead to dizziness and errors during manual calculation and maintenance.

[0006] (3) Manual switching: When switching, such as when changing the configuration code, it is necessary to accurately correspond to the physical switching point on site. If different people are responsible for the physical switching and the configuration code switching, it is easy for them to be out of sync.

[0007] Compared with the intelligent automation system, the traditional configuration code generation and switching writing method that mainly relies on manual calculation and maintenance communication switching has insufficient configuration code generation and switching accuracy, low quality assurance, and low efficiency. Summary of the invention

[0008] In order to overcome the defects of the above-mentioned prior art that manual calculation or maintenance is prone to errors and asynchronism is prone to occur during switching, the present invention provides a system and method for automatically calculating, generating and switching vehicle configuration codes.

[0009] In order to achieve the above-mentioned object of the invention, the technical solution of the present invention is as follows:

Among them, the configuration code algorithms of the same vehicle model with different configurations are the same.

[0017] Preferably, the configuration code algorithm determines whether each binary bit in the binary configuration code is filled with 1 according to different configuration characteristic values, and converts the filled binary configuration code into hexadecimal to generate a configuration code.

[0036] In order to more clearly understand the above objects, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific implementation manners. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0037] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited by the specific embodiments disclosed below.

[0038] Embodiment 1

[0039] Please refer to Figure 1 , Embodiment 1 of the present invention provides a system for automatically calculating, generating, and switching vehicle configuration codes, including:

[0040] A configuration information conversion unit, configured to convert the configuration information in the production vehicle configuration table into configuration characteristic values and issue the configuration characteristic values and corresponding configuration code algorithms;

[0041] A bill of materials system unit, including a bill of materials system (BOM), configured to generate material information according to the configuration characteristic values and issue it;

[0042] A design change management system unit, including a design change management system (GEC), configured to obtain switching first vehicle information and issue it;

[0043] A manufacturing management system unit, including a manufacturing execution system (MES), configured to receive the material information and the switching first vehicle information, automatically generate a configuration characteristic value derivative queue or a switching configuration characteristic value derivative queue, and issue it;

[0044] An electrical inspection equipment unit, including electrical inspection equipment, is used to receive the configured characteristic value derivation queue or switch the configured characteristic value derivation queue, vehicle identification code, and the configured code algorithm, automatically calculate and generate a vehicle configuration code, and write it into the production vehicle.

[0045] In this embodiment, the configuration table includes the optional information of the same vehicle model, and the vehicles are divided into different configurations according to the optional information. Among them, the configured code algorithms of the same vehicle model with different configurations are the same. The configured code algorithm determines whether each binary bit in the binary configuration code is filled with 1 according to different configured characteristic values, and converts the filled binary configuration code into hexadecimal to generate the configuration code. The logic of the configured code algorithm is the same as the configuration logic of the controller that controls different functions of the vehicle. For different vehicle models, if the controllers are the same, the same part applies the same configured code algorithm, so as to realize the platformization of the configured code algorithm. It should be noted that the configuration code finally generated by the electrical inspection equipment is in hexadecimal. Looking at the configuration code converted into binary, each byte in the binary represents a function-related item. 1 represents that this function or configuration exists, and 0 represents that this function or configuration does not exist. The algorithm uses different characteristic values to determine whether a certain binary bit is filled with 1, and after filling, it is converted into hexadecimal to generate the final configuration code. The logic of the function node controller is to fill according to the written hexadecimal configuration code information and then convert it into whether the relevant functions are turned on or off.

[0046] In some specific embodiments, the material information includes function identification information, vehicle model derivation, and configured characteristic values.

[0047] After scanning the switching first-piece card of the production vehicle, the design change management system unit obtains the switching first-vehicle information. When the production vehicle needs to perform a design change switch (such as part design change or vehicle system configuration change, etc.), it sends the switching first-vehicle information to the manufacturing management system unit to generate the switching configured characteristic value derivation queue. The switching first-vehicle information refers to the identification of the first vehicle and the function change switching information during the design change.

[0048] In some preferred embodiments, the manufacturing management system unit further includes a visualization interface, and the visualization interface will automatically distinguish and display different configured characteristic values with different characteristics for confirmation. In this embodiment 1, the different characteristics refer to colors.

[0049] In some preferred embodiments, the electrical inspection equipment unit includes electrical inspection equipment, and the electrical inspection equipment includes a computer or a single-chip microcomputer with a network connection function. The electrical inspection equipment also stores a standard file of configured characteristic values, and checks the received configured characteristic values before generating the configuration code to confirm whether the configured characteristic values are correct.

[0050] Please refer to Figure 2 , Figure 2 which is a schematic diagram of a configuration code provided in this embodiment. The configuration code in the figure is a hexadecimal number with 38 characters. With a large number of characters and a long length, it is easy to make mistakes during manual calculation and maintenance. Therefore, an automatic calculation, generation, and switching system for vehicle configuration codes provided in Embodiment 1 of the present invention can improve the accuracy of vehicle configuration codes, enhance the vehicle quality level, and solve the problems of manual calculation, maintenance, and switching errors of configuration codes.

[0051] Embodiment 2

[0052] Please refer to Figure 3 , based on Embodiment 1, this Embodiment 2 also provides an automatic calculation, generation, and switching method for vehicle configuration codes, which is applied to an automatic calculation, generation, and switching system for vehicle configuration codes described in Embodiment 1. The method includes the following steps:

[0053] S1: Obtain the vehicle configuration information table of the production vehicle, convert the vehicle configuration information therein into configuration characteristic values, and send down the configuration characteristic values and corresponding configuration code algorithm files;

[0054] S2: Send the configuration characteristic values to the bill of materials system unit, generate material information according to the configuration characteristic values, and send it down;

[0055] S3: When the production vehicle needs to perform a design change switch, scan the switching first-piece card of the production vehicle (at this time, the design change management system GEC will receive the vehicle identification number VIN of the production vehicle), obtain the switching first-vehicle information, and send it to the manufacturing management system unit;

[0056] S4: When the manufacturing management system unit receives the switching first-vehicle information, automatically generate the switching configuration characteristic value derivative queue according to the material information and the switching first-vehicle information, and send it to the electrical inspection equipment. At the same time, all subsequent production vehicles are sent down according to the switching configuration characteristic value derivative queue. Otherwise, generate the configuration characteristic value derivative queue according to the original material information and send it to the electrical inspection equipment unit. At the same time, display different configuration characteristic values in the derivative queue in different features on the visualization interface for personnel to confirm;

[0057] S5: After the electrical inspection equipment receives the configuration characteristic value derivative queue or the switching configuration characteristic value derivative queue and the configuration code algorithm, automatically proofread the configuration characteristic value derivative queue or the switching configuration characteristic value derivative queue. After verification, automatically calculate and generate the vehicle configuration code and write it into the production vehicle to complete the vehicle function configuration.

[0058] It should be noted that the Vehicle Identification Number (VIN) is scanned by relevant production personnel from the VIN information code of the vehicle and sent to the electrical inspection equipment of the electrical inspection equipment unit. The electrical inspection equipment compares the VIN code with the vehicle identification number in the switching first vehicle information sent by the Manufacturing Execution System (MES). After matching, the electrical inspection equipment automatically retrieves the corresponding configuration characteristic value derivative queue information and the configuration characteristic value standard file for verification. After verification, it automatically calculates and generates the corresponding configuration code in combination with the corresponding configuration code algorithm and writes it into the produced vehicle to complete the vehicle function configuration.

[0059] Embodiment 3

[0060] Embodiment 3 of this application is based on Embodiment 1 and Embodiment 2, and takes the design change switch for a specific function addition as an example.

[0061] For the design change switch of adding the front row driver's seat heating function to the vehicle model derivative M01:

[0062] Step S1: ① Convert the configuration information "driver's seat heating" function in the configuration table into the configuration characteristic value "FI02"; ② Send the configuration code algorithm corresponding to the configuration characteristic value to the electrical inspection equipment of the electrical inspection equipment unit. The configuration code algorithm logic is as follows: detect whether the VIN code matches. When the VIN code matches, judge whether there is the configuration characteristic value "FI02". If so, when generating the configuration code, write 1 to the configuration code of the seat controller, and also write 1 to the corresponding binary control bit of the configuration code of other function-related controllers.

[0063] Step S2: The BOM system of the Bill of Materials System Unit receives the configuration characteristic value and marks it with V1. The BOM system automatically generates the material information of "V1 + M01 + FI02" and sends it down (M01 is the vehicle model derivative identifier, and V1 is the function identifier information for adding the front row driver's seat heating function).

[0064] Step S3: When the design change V1 needs to be switched, the on-site switching personnel scan the switching first piece card of the production vehicle. The GEC system of the Design Change Management System Unit obtains the switching first vehicle information "V1 + VIN01", indicating that the addition of the front row driver's seat heating function starts from this vehicle. The GEC system will send the switching first vehicle information of "V1 + VIN01" to the MES system of the Manufacturing Management System Unit.

[0065] Step S4: The MES system of the manufacturing management system unit receives the material information and the first vehicle switching information, and automatically generates a configuration feature value derivation queue or a switching configuration feature value derivation queue (the material information can also additionally indicate whether it is a design change switch or use the receipt of the first vehicle switching information as the judgment rule for whether it is a switching configuration feature value derivation queue. In this Embodiment 3, it is a switching configuration feature value derivation queue). The MES system compares the "V1 + VIN01" information issued by the GEC system in Step S3 with the "V1 + M01 + FI02" issued by the BOM system in Step S2, and both have V1. Then, combined with the existing "M01 + VIN01" information in the MES system when producing vehicles (M01 is the vehicle type derivation identifier, VIN01 is the vehicle identification code identifier and is unique, and V1 is the function identifier information for adding the front row driver's seat heating function), if the match is correct, the MES system generates a switching configuration feature code derivation queue "VIN01 + FI02" and issues it to the electrical inspection equipment in the electrical inspection equipment unit. At the same time, different configuration feature values in the derivation queue are displayed in different colors on the visualization interface for personnel to confirm.

[0066] Step S5, after the electrical inspection equipment receives the switching configuration feature value derivation queue "VIN01 + FI02" and the configuration code algorithm, when the electrical inspection equipment identifies that the VIN01 code of this switching vehicle matches, it automatically proofreads the switching configuration feature value derivation queue with the configuration feature value standard file. After being correct, it automatically fills in according to ② in Step S1 and then generates the corresponding configuration code, and then writes it into the controller to automatically complete the design change switch for adding the front row driver's seat heating function configuration.

[0067] In summary of the above embodiments, compared with the prior art, the present invention provides a vehicle configuration code automatic calculation generation and switching system and method, which can realize the automatic calculation generation of the configuration code and the automatic switching of the configuration code, replace manual calculation and manual switching, no need to change the algorithm for new derivations, no need for developers to understand the configuration table and calculate again, and the feature values can be directly issued one by one according to the configuration table, eliminating the situation of misinterpreting the configuration table and other errors, improving the accuracy of the configuration code and the generation efficiency of the configuration code. When switching the configuration code, only need to scan the code on-site to bind the first piece card information of the switch and upload the VIN, and the system can automatically complete it, ensuring the synchronization of the switch and saving the communication cost during the switching process and the situation of asynchrony caused by transmission errors. The feature values and algorithms are managed on a unified platform, the rules are solidified, reducing the labor cost of development and recalculation, and the configuration feature values are simple and easy to understand and correspond one by one with the Chinese configuration table, facilitating verification and avoiding the outflow of defects. Improve the generation quality level of the vehicle configuration code and the overall production efficiency.

For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description.
