Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
It relates to programs that support design and verification.

[0002]

2. Description of the Related Art Conventionally, in the manufacturing industry that manufactures mass-produced industrial products, when mass-producing and selling a new product, a planning department that generally plans the specifications of the new product based on market trends investigated in advance ( (Planning process), a design department (design process) that designs the planned new product, and a production technology department (mass production process) that designs and organizes the assembly line to actually mass-produce the designed new product. -In a plurality of departments, such as a production department (production process) that actually mass-produces a new product in the organized assembly line, a plurality of workers have been working in chronological order.

Among the fields of mass-produced industrial products, in the field of automobiles, in order to achieve both improvement of working environment for workers and efficient production, first, in the production department, industrial equipment for production equipment is used. The introduction of robots and various assembly support devices has been advanced from an early stage, and has reached the present.

Further, in accordance with the dramatic progress in the arithmetic processing capability accompanying the development of computer technology in recent years, the CAD (Computer
aided Design) / CAE (Computer aided Engineering)
/ By utilizing a design support system that uses CAM (Computer aided Manufacturing) software, vehicle design, structural analysis, performance evaluation, virtual simulation of production equipment, etc. are virtually performed on a computer, and in the past ( It became possible to improve the efficiency of various operations that were performed by creating mockups and prototype vehicles multiple times.

As the efficiency of the work of the design department utilizing such a design support system increases, it becomes easy for the person in charge of the production engineering department to be involved in the product design from the stage of designing a new vehicle. As a result, in the mass production process, which is a post-process, the person in charge of the production engineering department can use the highly accurate design information (three-dimensional CAD information, etc.) inferred by using the design support system to efficiently It has become possible to organize and build various production equipment.

[0006]

As described above, in the field of automobiles, the design department (design process) is as described above.
The so-called concurrent engineering by the production engineering department (mass production process) is realized at a relatively high level, and efficient work is performed.

In response to such a current situation, a plan (specification) of a new model vehicle, which is planned by a planning department (planning process) that is in charge of the preceding process, generally includes various types of targets targeted by the new model vehicle. A large amount of documents describe a huge amount of items such as performance, specifications, cost, and performance comparison with a benchmark vehicle (comparative vehicle). For this reason, the person in charge of the planning department needs to spend a lot of time to express the expected new vehicle product concept in the plan document.

In addition, the management team of a company that develops and sells automobiles (including so-called managers) develops and sells new vehicles based on the proposals for new vehicles conventionally proposed by the planning department. However, it is not easy for a veteran manager to read the essence of planning a new vehicle from such a large amount of documents.

[0009] In general, the design department is generally involved in mass production design of the new model vehicle until the plan form (specification) of the new model vehicle is officially approved by the management as described above in the planning department. There are many cases where things cannot be officially done. Therefore, when the design department receives the approved new vehicle plan from the planning department, it positions the plan as an "absolute work instruction (master)" and starts specific design. It will be.

However, the plan written by the design department from the planning department includes the imbalance between the expected cost and the target performance, the feasibility of the vehicle layout, or the target performance in order to enhance the marketability of the new vehicle. May contain conflicting specifications.

Alternatively, even when the design of each part in the design department is barely completed, at the manufacturing stage of the prototype vehicle in which the prototype department is also involved, for example, due to the fact that interference is discovered unexpectedly, The planning department and the design department sometimes have to make a realistic and large-scale review of the layout around the interference point, and it takes considerable time before the final prototype car can be manufactured. There is.

In these cases, not only is the timing of launching the new model vehicle on the market delayed, but the productability of the new model vehicle is based on the concept originally intended by the planning department (that is, the productability of the new model vehicle as a whole). Will come off,
Leading to a serious problem.

In order to prevent the above-mentioned problems from occurring, an environment where the planning department and the design department can perform concurrent engineering is prepared so that the concurrent design department and the production technology department have already performed.・ It is possible to realize a comprehensive concurrent engineering environment between all departments involved in the development of new vehicles with engineering, but the design department that must perform realistic vehicle design with excellent cost performance is It is not always preferable to be involved in the work of the planning department, which is entrusted with the construction of the product characteristics of the above, because of the nature of the automobile product.

Therefore, in view of the current situation described above,
In the planning department (planning process), when planning a new vehicle,
Needless to say that the product is highly productive, there is a strong demand for a plan document (plan information) that can be realized by each department in the post-process and has a high degree of completion, in the shortest possible time.

Also, if each person in charge of the planning department has sufficient practical knowledge in each department of the post-process, a plan document including specifications that are difficult to realize, conflicting specifications, etc. will not be drafted. Although avoided, it is not realistic to think that each person in charge of the planning department should be able to use practical knowledge in all departments. However, the vehicle manufacturer already has a large amount of information generated during the design and mass production of existing vehicles. Since such information includes know-how for vehicle production in each department, it is necessary to It should be effectively used for planning and design.

Furthermore, the creation of three-dimensional CAD data in the design department based on the plan is a very time-consuming and time-consuming task, and especially when a design change is necessary to eliminate a defect, If it is possible to verify it after understanding in advance the impact of design changes on other departments, the development man-hours can be greatly reduced.

The present invention has been made in view of the above problems, and an object thereof is to automatically create three-dimensional CAD data by using existing data and reduce the development man-hours, and understand the influence of design changes in advance. It is to provide a program to support the planning, design and verification of new vehicles that can be verified above.

[0018]

In order to solve the above-mentioned problems and achieve the object, a program for supporting the planning, design and verification of the new model vehicle of the present invention uses a computer to set a preset vehicle model. A virtual layout means for executing a virtual layout based on specification data and past performance data, and three-dimensional CAD from the virtual laid-out data.
It functions as an automatic generation means for automatically generating data.

Further, preferably, the virtual layout data is data in which virtual parts are laid out on a planned vehicle.

Further, preferably, the virtual layout means estimates a defect in the layout, and the virtual layout means C
The solution to the problem is presented before the AD data is automatically generated, and the automatic generation means automatically generates the CAD data after the solution is approved.

Further, preferably, the virtual layout means presents a structurally insufficient portion of the planned vehicle based on the past performance data.

Further, preferably, when the design change is necessary for the planned vehicle, the virtual layout means presents the influence of the design change on the CAD data.

[0023]

As described above, according to the first aspect of the invention, the program for supporting the planning, design and verification of the new-type vehicle causes the computer to preset the specification data of the planned vehicle and the past data. The virtual layout means for executing the virtual layout based on the actual data and the automatic generation means for automatically generating the three-dimensional CAD data from the virtually laid-out data are used to utilize the existing data to make the three-dimensional CAD data. Can be automatically created to reduce the development man-hours, and it becomes possible to perform verification after understanding the effects of design changes in advance.

According to the second aspect of the present invention, the virtual layout data is data in which virtual parts are laid out on the planned vehicle. Therefore, the rough layout is verified at the planning stage, and then the three-dimensional CAD data is obtained. Can be automatically created.

According to the third aspect of the invention, the virtual layout means estimates a layout defect and
A solution to the problem is presented before automatically generating the CAD data, and the automatic generation means automatically generates the CAD data after the solution is approved, thereby eliminating the problem in the virtual layout in advance. Since the three-dimensional CAD data is created after obtaining the approval, it is possible to reduce subsequent design changes and the like, and to significantly reduce the design man-hours.

According to the invention of claim 4, the virtual layout means presents structurally insufficient parts of the planned vehicle based on the past performance data.
It is possible to eliminate defects in the virtual layout in advance and create three-dimensional CAD data, reduce subsequent design changes, and significantly reduce design man-hours.

According to the invention of claim 5, when the design change is required for the planned vehicle, the virtual layout means presents the influence of the design change on the CAD data, thereby making the design change possible. Approval can be obtained after presenting changes in test details to other departments in advance.

The supplier delivers various parts and modules (units) to the vehicle manufacturer.

A user terminal 2 such as a personal computer is provided in each of the above-mentioned departments. Each user terminal 2 is connected by a communication network 5 so that information can be transmitted and received, and the communication network 5 is further connected to a user terminal 2 provided to an external supplier (supplier of parts etc.). Has been done.

Further, the database 3 stores various kinds of information about existing vehicles, and the communication network 5
The user terminals 2 of the respective departments can be accessed through (details will be described later).

The server computer 1 is under the control of the planning department, for example, and refers to various information stored in the database 3 in accordance with the operation of the user terminal 2 of the planning department. , Supports planning of new vehicles by the operator (person in charge of the planning department) (details will be described later).

Since the configuration of each device for realizing the system configuration illustrated in FIG. 1 and the communication procedure itself are common at present, detailed description of this embodiment will be omitted. [Business Flow] Next, a characteristic business flow realized in the present embodiment using the system configuration described above will be described.

FIG. 2 is a diagram conceptually showing a work flow from the planning work of the new-type vehicle to the production technical work in the present embodiment. In the present embodiment, the prototype vehicle is planned after the new-vehicle planning is started. As shown in the same figure, the work by each department after the production and vehicle evaluation test and the start of mass production is roughly divided into "first step" and "second step".

<First Step> First, in the first step, the person in charge of the planning department carries out the planning support processing by the server computer 1 in accordance with the product concept of the new model vehicle constructed based on the market trends investigated in advance. By using, the detailed specifications of the new model vehicle to be planned are planned and the adequacy (feasibility) of the plan is verified with reference to the information on the plurality of types of existing vehicles stored in the database 3. The validity verification work is recursively and repeatedly performed in the planning department while adjusting the setting items until it is determined that the verification result by the server computer 1 can be realized (details will be described later).

The person in charge of the design department uses the user terminal 2 when the concept, performance, and layout of the new vehicle planned by the planning department are roughly gathered, and the three-dimensional shape of the new vehicle suitable for the concept is obtained. Start the design.

The planning information (data file group of digital information) of the new model vehicle, the feasibility of which has been confirmed by the verification by the planning department, is proposed to the management team of the vehicle manufacturer.

The management team of the vehicle manufacturer (including the so-called department manager) refers to the planning information of the new model vehicle proposed by the planning department and, if necessary, various information stored in the database 3 While referring to this, comprehensively judge whether or not to actually manufacture and sell the new model vehicle from the viewpoints of commerciality, schedule, budget, facilities and the like. When making a decision, if necessary, an improvement request is made to the planning department, and in that case, the planning department revises the planning information based on the improvement request and proposes the revised planning information to the management again. .

The planning information of the new model vehicle, which has been approved by the approval process, is positioned as an "absolute work instruction (master)", and the design department, the analysis department, etc., which is in charge of the post-process of the planning department. Will be officially distributed to each department.

The person in charge of the design department uses the work support software program such as CAD / CAE / CAM based on the plan information received as the design instruction to specifically design the new vehicle (mass production design). To start. Since the plan information includes or is associated with the information on the existing vehicles already stored in the database,
The design department can perform detailed design of a solid model or the like representing the three-dimensional shape of a new vehicle with a minimum of man-hours.

Then, when the mass production design in the design department has progressed to a certain extent, the person in charge of the analysis department uses various simulation software programs to virtually evaluate the performance and structure of the target new vehicle. And perform accurate analysis and improve the accuracy of mass production design information.

In addition, the shape design of the new vehicle, which is generated by the design department, has been approved by the management of the vehicle manufacturer separately from the plan information of the new vehicle, and the shape design of the new vehicle has been approved. The shape information indicating "" is officially distributed to each department such as a prototype department which is a back-end process of the design department.

<Second Step> In the second step,
When the mass production design in the design department is completed, the person in charge of the prototype department manufactures the prototype car using the design information (three-dimensional CAD information, etc.) of the new model vehicle designed by the design department. On the manufactured prototype vehicle, various evaluation tests and collection of the test results are performed by a person in charge of the experimental research department. The test result of the evaluation test of the prototype vehicle is reflected in the design information of the mass-produced vehicle by the design department.

Further, the person in charge of the production engineering department, when the mass production design in the design department is completed, according to the design information (three-dimensional CAD information) of the new model vehicle designed by the design department, CAD / CAE / CAM, etc. Using the work support software program of, the simulation of production workability, work ability and work organization in the assembly line will be started.

At this time, in the design / analysis department, the production technology department, and the prototype / experimental research department, the work is carried out by using various work support software programs and simulation software programs. Even if the design information initially passed to the post-process (production technology department) is provisional information in which detailed dimension design etc. (configuration) has not been performed, the post-process department concerned is It is possible to start the examination of the work in charge, and request improvement of the design department if necessary. When an improvement request is made, the design department revises the design information based on the improvement request,
The revised design information is handed over to each department in the subsequent process.

In the present embodiment, the planning information provided by the planning department is highly accurate information based on various information regarding existing vehicles stored in the database 3 (details will be described later). Therefore, in the second step, as conceptually shown in FIG. 2, the mass production design is optimized by the collaboration of the design / analysis department, the production technology department, and the prototype / experiment research department. ,
During this period, the planning information previously generated by the planning department (first step) is not substantially changed.

Then, the design information of the new model vehicle optimized in the second step (three-dimensional CA such as solid model)
(D information) is treated as a product model for mass production, and in a subsequent process (production process) not shown in FIG. 2, actual mass production is started according to this final design information.

Incidentally, as a concrete means for realizing the collaboration in the second step, a general design technique method or a simulation technique is adopted, and the detailed description in this embodiment will be omitted.

Further, in the second step, various information such as mass production design information of the new type vehicle, various analysis results, vehicle evaluation test results, etc. are displayed in the design department, analysis department, prototype / experiment research department, and production technology department. Is registered in the database 3 by the database 3, and the database 3 is updated by the actual latest information. Further, in the database 3, information such as a delivery date, a production lot, a cost (amount) of the parts or modules to be delivered to the vehicle manufacturer is registered by the user terminal 2 arranged in an external supplier. [Database 3] Next, information regarding a plurality of existing vehicles stored in the database 3 will be specifically described.

FIG. 3 is a diagram conceptually illustrating various information stored in the database 3 in this embodiment.

As shown in the figure, inside the database 3, there are: vehicle-level specification information and performance information regarding a plurality of types of existing vehicles; , Power train modules, chassis, etc.)
Specification information and performance information, -Specification information and performance information of multiple types of parts that make up each existing module, -Cost information of existing vehicles, existing modules, and existing parts-Existing vehicles, existing modules, And three-dimensional design information of existing parts (three-dimensional CAD such as solid model including three-dimensional shape and its dimension information and various attribute information)
Information) ・ Information about customers who purchased existing vehicles ・ Evaluation information such as opinions and complaints from customers who purchased existing vehicles ・ Benchmark vehicles that are sold by other manufacturers in the same industry (compared vehicles) Information (records) on various items such as vehicle-level specification information and performance information regarding the items are stored in a state of being associated with each other. These various types of information are stored at the vehicle level in order to make reference (reuse) efficient and easy.
It is managed in a systematically organized manner by three levels of classification: module level and component level. Here, the specifications are numerical information indicating dimensions and performance.

The database 3 in which the information on the above-mentioned various items is stored is SQL (Structured Query Language).
A general relational database (RDB) described by age etc. can be adopted.

In the present embodiment, various kinds of information regarding the vehicle stored in the database 3 are stored in the design department, the analysis department, the prototype / experiment research department, at the time of developing the vehicle, as described with reference to FIG. The information registered by the production technology department and the information registered by the external supplier, and the information about the customer and the evaluation information from the customer are registered by the store or the user. More specifically, the information set in the user terminal 2 arranged in each department or supplier is stored in the database 3 via the communication network 5. The database 3 is under the control of, for example, the server computer 1, and in that case, the operation of storing information received from the outside is
It is controlled by the server computer 1.

FIG. 4 is a diagram showing an example of the data format of each record stored in the database 3 in the present embodiment, which is the minimum unit among the three levels of classification of the vehicle level, the module level and the parts level. The information of a component level is illustrated.

That is, in the same figure, among a plurality of records relating to existing parts, a vehicle in which the tire is adopted as a record of a plurality of kinds of tires which have already been adopted or can be adopted in a plurality of kinds of existing vehicles. "Genre" and "Segment", "Chassis system", "Placement regulation conditions",
"Production / delivery information" and "size" as specification information
And "standard", and evaluation points of "ride comfort" and "steering stability (operation stability)" as performance information are shown.

Here, the "genre" represents the use and exercise performance of the vehicle, and in the present embodiment, there is a classification such as sedan, wagon, coupe and the like. The “segment” represents a vehicle class including the size of the vehicle and the displacement of the engine (including the output of the electric motor in the vehicle that uses the electric motor), and in the present embodiment, is a symbol such as A, B, or C. expressed.

The "arrangement regulation condition" is information indicating the regulation condition of the arrangement place when arranging the existing parts in the layout examination stage described later. "Production / Delivery Information"
Is information such as a production lot of existing parts and a delivery date.

Of the above-mentioned information items for each tire shown in FIG. 4, "genre" and "segment" are information representing the vehicle level association with the existing vehicle in which the target tire is adopted. . "Chassis" is
It is information indicating the module level association with the existing module in which the target tire is adopted, and the model XX, the model YY, ... Are the identification information. still,
The vehicle type that identifies each existing vehicle may be used or used as the information indicating the vehicle level association.

Therefore, when referring to the database 3 at the module level, records of a plurality of types of existing parts constituting the existing module are extracted using the identification information (model etc.) for identifying the existing module as a search key. It Further, when referring to the database 3 at the vehicle level, the identification information (genre and segment, or vehicle model) that identifies an existing vehicle is used as a search key, and a plurality of types of existing modules that make up the existing vehicle, and Records of a plurality of types of existing parts associated with the existing module are extracted.

In the present embodiment, the evaluation unit of the performance information corresponds to the three-level management system of the database 3 and constitutes the vehicle level (entire vehicle), the module level configuring the vehicle, and one module. It is classified into three levels of parts. A standardized evaluation point (evaluation value), which is a common measure, is stored in advance in the performance information of various items belonging to those levels.
As an example, the most common 10 points (0 to 10 points)
It is represented by. In the present embodiment, a huge amount of information generated in designing / analyzing / vehicle evaluating / testing / manufacturing a plurality of types of existing vehicles is stored in the database 3 in such a system, and the information is tangibly and intangibly included. Effectively utilize the know-how of each department to make vehicles for planning new vehicles.

The server computer 1 executes the database 3 according to the software program stored in the memory in advance when executing the planning support for the new vehicle.
Is accessible. In addition, the operator (user) of the user terminal 2 arranged in each department (including the supplier)
Is the database 3 within the preset allowable range.
Maintenance such as addition, update, or deletion of information stored in can be performed. [New vehicle planning support processing] Next, FIGS.
With reference to No. 1, the planning support process used by the person in charge of the planning department when planning a new vehicle will be described in detail. This support processing is performed by the CPU of the server computer 1 according to the operation of the operator at the user terminal 2.
(Not shown) is realized by referring to the above-mentioned database 3 by executing a program stored in advance in a storage medium (hard disk device or the like).

The support process is started by the person in charge of the planning department who has the predetermined identification information (ID) logging in to the user terminal 2.

In the following description, the function of displaying various screens having predetermined input items on the display of the user terminal 2 by the server computer 1 and the information set in the input items of the displayed screens will be described. A general procedure is adopted for a function of acquiring from the user terminal 2 and a function of searching the database 3 with a predetermined search key to acquire necessary information, and detailed description thereof in the present embodiment will be omitted. .

When the processing is started, the menu screen shown in FIG. 5 is displayed on the display of the user terminal 2. A "new plan" button 51, a "planned vehicle file" button 52, a "various data reference" button 53, and a "close" button 54 are displayed on this menu screen. In the menu screen shown in FIG. 5, the “new planning” button 51 is selected when a new vehicle is newly planned, and the “planned vehicle file” button 52 is already on the server computer 1.
Is selected when reading out the plan information of the new model vehicle stored in, and the "various data reference" button 53 is selected when referring to various information stored in the database 3 in the logged-in user terminal 2. ,"close"
The button 54 is selected when canceling the login to the user terminal 2.

When the "new plan" button 51 is selected in FIG. 5, the menu screen shown in FIG. 6 is displayed.
In the menu screen shown in FIG. 6, the "Start planning" button 55
When is selected, the process of newly planning a new model vehicle is started, and when the "planned car search" button 56 is selected, a process of searching for plan information of the new model vehicle already stored in the server computer 1 is started. Then, when the "various data reference" button 57 is selected, the process of referring to various information stored in the database 3 in the user terminal 2 is started, and when the "return" button 58 is selected, the process shown in FIG. Returns to the initial screen.

When the "start planning" button 58 in FIG. 6 is selected, the new model data input screen in FIG. 7 is displayed. In the input area 59 of the menu screen of FIG. 7, various target specifications which are desired to be realized at the vehicle level in the new vehicle are input by the operator. The target specifications to be input to the input area 59 include, in addition to the driving method, genre, segment, size (total length, width, height), weight, etc., illustrated in FIG. There are items such as height, minimum ground clearance, passengers, minimum turning radius, wheel base, and tread.

When inputting the target specifications to each item,
Set the target value and its allowable value (allowable range) to the target evaluation point (1
It is necessary to set it with 0 points. In this embodiment, when the operator does not set the allowable value or 0 (zero) is set, the server computer 1
Judges that the target value of the corresponding item has an absolute positioning for the operator, does not give an allowable range to the target value, and performs the calculation with the target value as it is. In this way, the user himself / herself can arbitrarily set the allowable range, so that the support processing by the uniform automatic calculation of the server computer 1 can be made flexible, and the convenience is improved.

Further, in the input area 59 of FIG. 7, the operator can set the priority rank instead of specifically setting the desired allowable value for the target value. There are several types of priority ranks (A, B,
C and the like) are prepared in advance, and the operator can select any of the items. Within the server computer 1, a corresponding allowable range is preset for each priority rank. For example, the width of the allowable range in the + direction and the-direction around a certain target value is A <B. <C <... is set.

When the necessary data is input to the input area 59 of FIG. 7, the target performance input screen of FIG. 8 is displayed. Figure 8
In the input area 60 of the menu screen of 1, the operator inputs the target performances of a plurality of items that the new type vehicle wants to realize at the vehicle level. Items of the target performance that should be input to the input area 60 include steering stability, riding comfort, power performance, fuel consumption, and the like illustrated in FIG. When inputting the target performance to each item, the target number of points is set as a value representing the target performance to be realized in the new model vehicle according to the various performance items stored in the database 3 at the evaluation points. And the permissible value (permissible range) of the target evaluation point (1
It is necessary to set it with 0 points. In the target column, each target performance is ranked as a "leader" in the top class among a group of existing vehicles (including comparison target vehicles) or in an average class among a plurality of existing vehicle groups. Amangu "can be set. For example, "leader" has an evaluation score of approximately 8 points or higher, and "amangu" corresponds to an evaluation score of 6 to 7 points.

When the "details input (module level)" button 61 is selected on the menu screen of FIG.
The module-level target performance input screen shown in is displayed. This screen shows the state when setting the target performance to the "chassis related" module among the multiple types of modules that make up the new model vehicle that is being planned, and the operator's input operation as the front and rear suspension As a result, an existing part having an evaluation point of 6.5 points stored in the database 3 is set as a carryover part, and the input area 62 has a maneuverability of +1 as an improvement target for the 6.5 evaluation points. +0.5 in points and ride comfort
Points have been entered.

At this time, the validity of the changed evaluation value is judged based on the degree of improvement of the past evaluation value of the corresponding item stored in the database 3, and it is judged to be invalid. In that case, the operator is notified to that effect. For example, every time design updates were made several times in the past, the average score was improved by +0.5 points. , +1.5 points is set as the improvement target, it is generally difficult to realize. In such a case, the fact is notified to the operator.

As described above, in this embodiment, when the user (the person in charge of the planning department) sets an evaluation value that is difficult for the person in charge of the design department who is in charge of the post-process to realize, the fact is notified. Therefore, it is possible to prevent unplanned new vehicle plans from being planned. Therefore, by using the specification information and performance information of existing vehicles, the accuracy of the plan verification and the planning A good balance can be achieved with the degree of technological progress expected when the design department actually designs and develops the target new vehicle.

Here, the carry-over part is an existing part that is desired to be adopted in the new model vehicle to be planned, and includes a three-dimensional shape and its dimension information, and various attribute information. Three-dimensional CAD information such as a solid model to be stored is already stored in the database 3.
One functional unit composed of a plurality of carryover parts (existing parts) is called a carryover module.

On the module-level target performance input screen shown in FIG. 9, the tires to be used with the front and rear suspensions are set by the operator's input operation. Further, on this screen, the necessity of setting 4WS, power steering, ABS, etc. can be set.

Further, on the menu screen shown in FIG. 10, it is possible to set the target performance for the power train as an important module that determines the dynamic performance of the new model vehicle among the target items regarding the plurality of types of modules. On this menu screen, the operator can select a desired one from a plurality of types of engines and transmissions registered in the database 3 as existing parts (existing modules).

The records of the existing parts (existing modules) stored in the database 3 are associated with the evaluation points of the performance items or the actual values of the specification items as information indicating the capabilities (actual capabilities) at the present time. Therefore, the operator wants to improve the evaluation value for the desired existing parts (existing modules) such as the selected engine and transmission in the design of the new vehicle by the design department (the current performance of the existing parts etc.). To the extent that you want to improve)
Can be set in the input area 63 of the menu screen shown in FIG. However, at this time, the validity of the changed evaluation value is judged based on the degree of improvement of the past evaluation value of the corresponding item stored in the database 3, and is judged to be invalid. Is notified to the operator. As a result, the accuracy of planning and verification is improved by using the specification information and performance information of existing vehicles, and the degree of technological progress expected when the design department actually designs and develops the new vehicles to be planned. And can be balanced.

When inputting the target performance at the module level, it is possible to select the existing parts or modules desired to be adopted in the new model vehicle to be planned in the input area 64 of the carryover setting screen shown in FIG. it can. That is, when any existing vehicle registered in the database 3 is selected by the operator by operating the “select existing vehicle” button on this screen, the solid model or the like, which is the design information of the corresponding existing vehicle, is used. Then, the three-dimensional model of the existing vehicle is displayed on the display of the user terminal 2. The operator selects, from the three-dimensional model displayed on the display, the existing parts or modules that make up the existing vehicle,
As illustrated in FIG. 15 and FIG. 16, it is possible to select a carryover component or a carryover module to be adopted in a new model vehicle by a selection operation using a pointing device such as a mouse.

FIGS. 15 and 16 are views exemplifying a model of a three-dimensional shape of an existing vehicle in which a carryover setting has been made by the operator. In FIG. 15 and FIG. 16, parts where the carryover setting has not been made are hatched. The part that has been set is displayed in white.

The existing parts or modules selected on the carry-over setting screen of FIG. 11 are assumed to be used as they are (design) even when they are adopted in the new model vehicle to be planned. In this system as well, although some manual setting of improvement targets is allowed as shown in FIG. 9, in principle, the performance information and specifications information of the existing parts or modules for which carryover setting has been performed cannot be performed by an operator or It is restricted to be largely updated in the calculation for the plan verification.

At the stage where the vehicle-level and module-level target performances and target specifications of the new-type vehicle are set by the above-mentioned procedure, the operator uses the display screen shown in FIG. Can be done. The verification result calculated based on the set target performance and target specifications is presented to the operator of the user terminal 2.

When the "planned vehicle image" button 71 is selected on the display screen shown in FIG. 12, a new model vehicle to be planned is based on the target performance and target specifications set in the above-mentioned steps. Is displayed on the display of the user terminal 2.

However, the shape of the vehicle displayed at this time does not have a design (shape design) peculiar to the vehicle, and the genre and segment of the new vehicle input on the input screen of FIG. Based on the shape of the occupied space that is largely determined by the vehicle shape that reflects the size information set on the same setting screen as the base, the existing vehicle shape selected as the base vehicle shape (simple body) It is a graphic to the extent that modules (including carryover modules) and existing parts are arranged. When arranging the existing modules and existing parts with respect to the base vehicle shape, the arrangement regulation conditions associated with the individual existing parts and existing modules, which are stored in the database 3 as illustrated in FIG. 4, are referred to. It

More specifically, for the simple body determined based on the genre, segment, and size of the vehicle set previously, the same three-dimensional design information of various existing modules is used to make the same. The main components of the vehicle are automatically arranged in the coordinate space according to the arrangement regulation conditions stored in a state associated with the database 3. At this time, 3 of various existing modules
The dimensional design information is not used as it is, but for example, in order to arrange and move individual components at the level of a three-dimensional box such as a cube or a cylinder, the external dimensions (length, width, height) included in the design information. ) And the information of the position of the center of gravity are used, and the detailed design shape of each part expressed as a solid model and the attribute information are not used.

However, when an existing module is used as a carry-over module, it is premised that the existing model will be used as it is even in the new model vehicle to be planned, so the three-dimensional design information of the existing module is used as it is. It is advisable to construct the vehicle so that a new vehicle with high economic efficiency can be easily planned by using it and restricting the layout change.

The components automatically arranged in the simple body are main components such as tires, suspension modules, engine modules, steering wheels, seats, instrument panels, fuel tanks, etc., and the arrangement regulation conditions associated with them. According to the above, it is automatically arranged for the simple body.

For example, when automatically arranging with respect to a simple body, the arrangement regulation condition is that the center of gravity of the tire is located at the center position of the tire house in the case of a tire, and the nth front member in the case of an engine module. It is a placement restriction condition that it is placed at a position from ** mm to the back. The graphic displayed in this case is for the operator who is the person in charge of the planning department to judge the adequacy of the project. Therefore, if the layout regulation conditions can be satisfied, the existing modules and The placement is done with some allowance for existing components to interfere.

As a result, the display screen for the user to verify the feasibility of the minimum required layout is arranged in such a manner that individual existing modules and / or existing parts are allowed to interfere with each other. The processing required for component layout can be speeded up. In addition, the operator can easily verify the feasibility of the physical layout of the new vehicle.

FIG. 17 is a diagram exemplifying the layout verification result for the new model vehicle to be planned when the “layout” item is selected in the area 81 shown in FIG. 13, and in the display screen shown in FIG. When the "planned vehicle image" button 71 is operated, the user terminal 2
As an example of the graphics displayed on the display, the engine room is viewed from above.

In the layout verification, the operator appropriately moves each component, which is automatically set in the simple body by the server computer 1 as described above, by a selecting operation using a pointing device such as a mouse. It is possible to consider.

In the display screen shown in FIG. 12,
When the “validation of planned vehicle” button 72 is operated, the menu screen shown in FIG. 13 is displayed. This menu screen displays a number of items that can be evaluated for adequacy with regard to the new model vehicle that is being planned. Those that have all the original settings are displayed in white, and those for which some information is not set are displayed in hatching.
The operator is notified to that effect.

For items for which information setting is insufficient, when the operator operates the "to data input screen" button 82, the operator returns to the setting screens described in the above steps and requests the desired data. The value of can be entered individually.

Items for which information setting is insufficient are stored in the database 3 on the selection screen shown in FIG. 14 when the “verify by sample input” button 83 in FIG. 13 is operated by the operator. By selecting the performance information and specifications information about existing existing vehicles as a sample, the target performance and specifications required for the validity evaluation of the relevant items are collectively set in the server computer 1. Therefore, the input operation by the user can be simplified.

Next, on the display screen shown in FIG.
When the "Comparison of performance of planned vehicle" button 73 is operated, the expected evaluation value of the new model vehicle to be planned is calculated as described above based on the target performance and target specifications set in the above-mentioned steps. Then, among the existing vehicles registered in the database 3, the comparison with the evaluation value indicating the ability of the comparison target vehicle is displayed on the display of the user terminal 2 for each vehicle, for each performance item, or for each module.

When the "virtual test" button 74 shown in FIG. 12 is operated, the target performance and target specifications set in the above-mentioned procedures and the existing vehicle registered in the database 3 are described later. A virtual test is performed based on the virtual test result and the actual vehicle test result, and the virtual test result is displayed on the display of the user terminal 2.

As in the present embodiment described above, the planning information of the new model vehicle created by the planning department using the server computer 1 is already used in the conventional vehicle in each process such as design, analysis, vehicle evaluation test and the like. It is the information created based on the realized real information. For this reason, the information is more accurate than the specifications described in the conventional plan documents, and the design department that received the plan information uses the plan information as an “absolute work instruction sheet” as it should be. The concrete mass production design can be started immediately.

Further, even for the management team of a company that has to decide whether to develop or sell a new vehicle, the planning department judges the plan of the new vehicle proposed before the mass production design by the design department. At this time, if the planning information summarized as in the above-described embodiment can be referred to, the planning information is systematic information based on the actual information already realized in the conventional vehicle, and if necessary, Since it can be displayed graphically, it is possible to imagine concretely and easily the items to be examined, such as the product characteristics and validity of the new model vehicle to be judged, as compared to the case of referring to a document as in the past. A more accurate decision can be made quickly.

As described above, according to the above-described new vehicle planning process, the user uses the setting screens shown in FIGS. 7 and 8 to set the target specifications and the target performance of the new vehicle to be planned. -If set in the computer 1, the information indicating the possibility that the new vehicle will actually be established is automatically calculated by referring to the information about the existing vehicle, so that a realistic and highly accurate new vehicle planning can be performed quickly. And it can be performed easily. As a result, it is possible to shorten the entire period from the planning of a new vehicle to the start of mass production.

The operator can easily use the carry-over parts and / or carry-over modules, which are often used when planning a new vehicle, on the server computer 1 by using the setting screen illustrated in FIG. Information that can be set and that represents the possibility that a new model vehicle will be established in the state where the set carryover parts and / or carryover modules are taken into consideration is calculated, so that a highly economical new model vehicle can be easily planned. be able to. [Use of virtual test results in the planning stage] In the planning department, target specifications and target performances set in advance in the planning process described above, or virtual test results created in the analysis department by past planning and created by the experimental research department Server based on a database of existing actual vehicle test results
A virtual test can be performed on a new-type vehicle by using the computer 1 according to the procedure shown in FIGS.

On the other hand, in the analysis department, when creating a database of the above existing virtual test results, the design information of the new model vehicle designed by the design department is utilized by various simulation software programs as described above. Virtual analysis (virtual test) is performed to verify the performance and structure of the target new vehicle.

FIG. 19 is a conceptual diagram of the virtual test. At the vehicle level, module level and component level, the correlation between the actual vehicle test result and the test result by the simulation model is obtained, and the parameter study by the simulation model is performed. Create a database of results.
As a result, verification of the simulation model (correlation between the actual vehicle evaluation and the simulation evaluation and creation of a simulation model database), verification of the direction / feasibility of the target performance (simulation model evaluation at the stage where there is no prototype vehicle) It becomes possible to decide the actual vehicle test items using the simulation model, and it will be made into a database as a source of virtual tests to be executed in the planning department in the next planning.

FIG. 20 shows an example of a screen showing the results of the virtual test carried out by the planning department. The virtual test is carried out by selecting the "virtual test" button 74 on the display screen of FIG.

As shown in FIG. 20, the virtual test result displays the virtual test status and the number of test items corresponding to each level subdivided into five levels as the reliability, and particularly the levels 0 to 0 are displayed.
For test items with low reliability up to 2, detailed items and identification numbers (brackets) are displayed. Further, regarding low-reliability test items of levels 0 to 2, it is displayed that a real vehicle test using a prototype vehicle is essential as a solution.

In the above levels 0 to 4, level 0 cannot be analyzed by the virtual test, level 1 requires the actual vehicle test using the prototype vehicle (the reliability of the virtual test result is low), level 2
Requires an actual vehicle test using a prototype vehicle (the reliability of the virtual test result is low), but the virtual test result can also be used as an auxiliary. Level 3 is almost acceptable for analysis using the virtual test, level 4 is Each represents the reliability that only the analysis by the virtual test is possible (the reliability of the virtual test result is the highest).

The reliability of the virtual test result is, for example, the deviation between the past (existing) simulation data and the actual vehicle test data, the amount of the existing actual vehicle test data, the target specifications and the target performance of the planned vehicle and the existing vehicle. It is determined by the degree of approximation of.

By selecting the detail list button 107 in the figure, the virtual test item and the reliability of the virtual test result are displayed in detail. FIG. 21 shows the virtual test items and the reliability of the virtual test results verified by using the simulation model for the main structure (specification data) and main change structure (change data for existing data) of the planned new model vehicle. It is an example of list display illustrated, and a detailed list in which the reliability of the virtual test result is subdivided into 5 levels from level 0 to 4 is displayed for each virtual test, and the result of level 0 is colored so that the operator can identify it. You may output by adding or voice.

Further, as shown in FIG. 21, the detailed list of the virtual test results includes a vehicle level (for example, a test regarding power performance / fuel consumption), a module level (a test regarding braking performance and a power train), and a component level ( Although it is hierarchically set for each test related to the wiper washer, only virtual test items (eg, component level and module level) that can be executed at the current planning stage are displayed and other items (vehicle level) are displayed. ) Is displayed face down.

Further, the symbol "x" shown in the above list indicates that the relevant test items for the main structure and main modified structure of the new model vehicle cannot be carried out due to lack of data.

To add further explanation, the support system of the present embodiment is intended to reduce the number of prototype vehicles in the process from planning of a new vehicle to mass production, and preferably to abolish the prototype vehicles. Therefore, based on the virtual test result shown in FIG.
It is configured so that conditions can be set that reduce or eliminate prototype cars.

FIG. 22 exemplifies a prototype vehicle adjustment screen for setting conditions for reducing or eliminating the number of prototype vehicles described above. The item 101 (priority test adjustment with reduction in prototype vehicles) having the highest priority is given. From top to bottom, in order from top to bottom, "test adjustment with significant changes in content" item 102 (priority level 2), "test adjustment with changes in material supply destination" item 103 (priority level 3), "development" Items such as “test adjustment with shortening of period” item 104 (priority order 4) and “test adjustment with efficient use of prototype vehicle” item 105 (priority order 5) can be selected.

By selecting any of the detail input buttons 101a to 105a for each item in FIG. 22, in the "test adjustment with reduction of prototype vehicle" item 101, for example, input of the number of prototype vehicles, In the "test adjustment with change" item 102, for example, a change in the suspension type or the number of doors is input, and in the "test adjustment with a change in the material supply destination" item 103, for example, change input of the material supply destination such as transmission or ABS, "development" In the "test adjustment with shortening period" item 104, for example, the development period can be input, and in the "test adjustment with efficient use of the prototype vehicle" item 105, for example, a numerical value of the degree of deterioration (%) of the prototype vehicle can be input. There is.

Furthermore, the weighting button 101b is set so that the relative importance of each of the items entered above can be arbitrarily set.
By selecting ~ 105b, weighting can be set for each item.

FIG. 23 is a screen example illustrating the actual vehicle test items as the adjustment results in the “test adjustment involving reduction of prototype vehicles” item 101 having the highest priority. The virtual test results and / or the diagram of FIG. It is possible to display the actual vehicle test items of the prototype vehicle to the experimental research department based on the input information on the prototype vehicle adjustment screen 22.

In the actual vehicle test items of the screen example of FIG. 23, for example, the durability road test,
It is displayed to present the rear door side opening strength test, rear door side opening durability test, rear door side opening vibration test, etc.

Then, regarding the displayed actual vehicle test, the expected evaluation point as the degree of achievement of the target performance within the range that can be assumed based on the virtual test result and the existing actual vehicle test result, and the problems inferred from these test results ( Swing arm crack possibility or suspension tower deformability etc.)
Is specifically displayed as a numerical value or the like. When the above-mentioned expected evaluation points and problems cannot be predicted, “Unknown” is displayed as in the illustrated rear door side opening test item.

By selecting the detail list button 108, the vehicle performance assumed to be possessed by the prototype vehicle is displayed based on the improvement measures for approaching the target performance and the actual vehicle test items.

In the screen of FIG. 23, based on the virtual test result and the existing actual vehicle test result, a prototype vehicle and an actual vehicle test item using the prototype vehicle are displayed to be presented to the experimental research department. Specifically, the prototype vehicle No. 1 in the figure has a full-scale collision actual laboratory, the prototype vehicle No. 2 has vibration actual laboratory, and a prototype vehicle 3
In the issue, it is displayed as Body Research Institute.

In addition to the above-mentioned prototype vehicle and actual vehicle test items using the prototype vehicle, for example, the conditions set in the "test adjustment with efficient use of prototype vehicle" item in the prototype vehicle adjustment screen of FIG. Display the efficient test process (procedure) accordingly. Specifically, as shown in the figure, in order to efficiently use the prototype vehicle for prototype vehicle No. 2, test in the order of vibration actual laboratory → strength actual laboratory → reliability actual laboratory (full spec). Is displayed in. Further, by selecting the detail list button 109, the detailed contents of the actual laboratory and the procedure corresponding to each prototype vehicle are displayed.

In the display of the prototype vehicle and the actual vehicle test items using the prototype vehicle, the information input to the “test adjustment with reduction of prototype vehicle” item having the highest priority among the conditions set in FIG. 22 is displayed. As the highest priority, lower conditions are given priority in order from the highest priority condition. Further, the actual vehicle test having a large estimation problem is prioritized, and, for example, as shown in FIG. 23, the prototype vehicle No. 3 displays the body actual test (rear door strength test) → rear door vibration test. In addition, conditions such as "test adjustment involving major changes in content" and "test adjustment involving changes in material supply destination" that have a negative impact on the reliability of virtual test results and existing vehicle test results are prioritized. To be done.

As in the present embodiment described above, the planning information of the new model vehicle created by the planning department using the server computer 1 is already used in the conventional vehicle in each process such as design, analysis, and vehicle evaluation test. It is the information created based on the realized real information. For this reason, the information is more accurate than the specifications described in the conventional plan documents, and the design department that received the plan information uses the plan information as an “absolute work instruction sheet” as it should be. The concrete mass production design can be started immediately.

Further, even for the management team of a company that has to decide whether to develop and sell a new vehicle, the planning department judges the plan of the new vehicle proposed before the mass production design by the design department. At this time, if the planning information summarized as in the above-described embodiment can be referred to, the planning information is systematic information based on the actual information already realized in the conventional vehicle, and if necessary, Since it can be displayed graphically, it is possible to imagine concretely and easily the items to be examined, such as the product characteristics and validity of the new model vehicle to be judged, as compared to the case of referring to a document as before. A more accurate decision can be made quickly.

Further, according to the present embodiment, since a new vehicle having a high degree of completion can be planned by the support system using the server computer 1, the development period of the new vehicle is greatly shortened, and the number of prototype vehicles is reduced (solved). ), Development costs can be reduced. [Automatic Generation of Three-Dimensional CAD Data] In the system according to this embodiment, it is possible to perform verification by a virtual layout in which virtual parts are laid out on a planned vehicle as illustrated in FIG.

In the verification by the virtual layout, the server
The layout can be examined while the operator appropriately moves each component automatically set in the simple body by the computer 1 as described above by a selection operation using a pointing device such as a mouse.

Then, the design department uses a work support software program such as CAD / CAE / CAM based on the plan document (digitalized plan information in this embodiment) of the new model vehicle. 3D CAD data can be automatically generated from the data used for the above virtual layout by using the server computer 1 as one of the design works. The number of man-hours required for design can be significantly reduced as compared with the conventional case.

FIG. 18 shows an example of three-dimensional CAD data automatically generated from virtual layout data. The virtual layout data is linked to the existing CAD data of the vehicle, the module, and the parts, and the existing CAD data is read from the link destination at the time of execution of automatic generation to create three-dimensional CAD data.

Further, as in the example of the virtual layout in FIG. 17, a portion (such as interference or heat damage) on the virtual layout or a structurally insufficient strength is determined based on the existing actual vehicle test results. Before guessing and automatically generating the three-dimensional CAD data, a warning is displayed at the location by color, voice, or the like, and a substitute component or the like is displayed as a solution to the problem (display screen 92 in FIG. 17). ). Also,
In the design department, three-dimensional CAD data can be automatically generated by selecting the automatic generation button 91 after the solution is approved by the general department that supervises each department until the completion of the planned vehicle.

Then, in the design department, the automatically generated three-dimensional CAD data is appropriately modified based on preset target specifications, target performance, existing data and the like.

Furthermore, when a design change is required in the design department in order to solve the above-mentioned problems, etc., the influence on other departments due to the change of the test contents due to the design change,
In other words, reexamination of interference points and improvement points in the design department,
Alternatively, it is possible to warn each department of the necessity of re-testing in the analysis department or the experiment department, and to present it so as to prompt approval (display screen 93 in FIG. 17), and after understanding the effects of design changes in advance. Can be verified with.

The automatically generated three-dimensional CAD data is created for each vehicle, each module (or each part assembly area), and each part at each design stage in the design department. Non-conformance information that does not conform to the regulatory data to be imposed on the vehicle can be added so that it can be displayed for each part on the design drawing, and warning and approval are given to the related departments that have set the non-conformance information.

If the nonconformance information is added to the design drawing, a department (for example, a planning department, a design department, an intellectual property department, a marketing department, etc.) related to the nonconformance information makes a request, and Until the improvement measures are approved for the non-conformance information, it is impossible to proceed to the next design stage in the actual vehicle experiment in the experimental research department and the design department.

The above regulatory data is based on domestic and foreign legal regulations,
It is at least one of information regarding the existence of intellectual property rights such as internal standards, patent rights (including pending applications), future acquisition possibility of the rights, customer requests, and design know-how, and it is classified into multiple levels according to their importance. It is divided and can be set in related departments.

Specifically, domestic and foreign laws and regulations are the most important level 0, internal standards are the next most important level 1, and the existence of intellectual property rights such as patents and future acquisition of such rights. The possibility is set as level 2, the customer request is set as level 3, and the design know-how is set as level 4 according to the importance.

The regulation data can be set according to the design stage, and the regulation data is changed at each design stage.

As described above, all the regulation data can be easily obtained at each design stage, and the verification can be efficiently performed. Therefore, the design can be proceeded while taking measures against the regulation data in advance. [Presentation of actual vehicle test items] Fig. 24 shows an example of a display screen of actual vehicle test items presented to the experimental research department. At the stage when the plan is approved and the prototype vehicle is completed, the experimental research department receives virtual test results and Actual vehicle test items using a prototype vehicle are presented based on past actual vehicle test results.

As shown in FIG. 24, for example, as a braking test, a rapid braking of 60 km / h,
Each test item of 100km / h of sudden braking and ABS sudden braking, and the necessity of the actual vehicle test of these items (whether the reliability of the virtual test result is acceptable or not) are displayed, and the virtual test result and other Test items that cannot be complemented in the actual vehicle test are presented.

As an example of the above-mentioned additional test, the vibration test in the figure is performed at a place other than the test course used for the braking test, and the G method is attached to the suspension as a test method, and the test item number is Is displayed.
In addition, as a result of the design changes made in the design department in response to the above-mentioned actual vehicle test results on the test results, it is possible to present to other departments the presence or absence of retest items and the reliability of the test results. Be converted.

According to the present embodiment, the support system using the server computer 1 reduces the number of prototype vehicles at the planning stage, and prevents the actual vehicle tests using the prototype vehicles from being duplicated, thus improving the efficiency of the prototype vehicle. As a result, it is possible to significantly shorten the development period of new vehicles, reduce (eliminate) prototype vehicles, and reduce development costs.

A storage medium storing a computer program for executing the processing procedure of the server computer described above is supplied to the computer, and the computer reads the program code stored in the storage medium to perform the processing described above. May be executed.
