The consideration of information was designed with only the approximate bundle thickness without any consideration. Therefore, it was impossible to check detailed interference with other parts in the vehicle and calculate accurate bundle branch information.

Conventionally, the assembly diagram was drawn up based on the wiring information and actual vehicle status or CAD length information in the circuit diagram, and the evaluation list of the wire harness was used for various investigations such as wire usage, connector type and number, clips, protectors, and exteriors. There was a problem of estimating the enemies with the help or by looking at the drawings.

The present invention is to solve the problems of the prior art as described above, to support the design of the wire harness of the vehicle that can be utilized for the current vehicle model analysis and advance review when developing a new vehicle model by maintaining and managing the circuit connection information and the inherent properties of the parts It is an object of the present invention to provide an apparatus and method.

The main controller 10 serves to control the module required for the wire harness design of the vehicle.

The wire harness design method using the wire harness design support apparatus of the vehicle having the above structure includes automatically setting a unique database environment for each vehicle type through the vehicle management module 11 under the control of the controller 10, and a power supply system. Registering the power system of the vehicle through the module 12 and creating a power system table; creating and registering the electric symbol through the electric symbol preparation module 13; and through the unit circuit diagram preparation module 14 Creating a single circuit diagram using an electrical symbol applied from the electrical symbol creating module 13, and using a single circuit schematic applied from the single circuit schematic creating module 14 through a system circuit diagram creating module 15 A circuit diagram is prepared, and a system diagram applied from the system circuit diagram preparation module 15 is arranged through the comprehensive circuit diagram preparation module 16, and a wiring is established.

Next, the stepwise operation of the wire harness design through each module will be described with reference to FIGS. 2 to 11.

Referring to FIG. 2A, the vehicle model management module 12 is for maintaining information on all vehicles required for the wire harness design and operating information maintained and managed during the wire harness design, and the vehicle required for the wire harness design. Maintaining information about is divided into two parts. One is the entire standard data storage 111 for database-maintaining and maintaining the entire standard data, which is information common to all vehicles when the wire harness is designed, and the other is the database for maintaining and maintaining the unique information for each vehicle model during the wire harness design. The vehicle type data storage unit 112. The entire standard data storage unit 111 of the vehicle model management module 11 includes a storage area in which data on a power supply name required for a power supply system of a vehicle model is stored in a database, and a fuse name and a fuse argument required for the power supply system of a vehicle model. It is composed of a storage area in which the data for the database is databased, and a storage area in which the data for the parts required for the power system of all vehicle types are databaseized.

The vehicle-specific data storage unit 112 includes a plurality of vehicle-specific data storage means 112a-112n in which vehicle-specific data corresponding to a plurality of vehicle types are each databased, and each vehicle-specific data storage means 112a- 112n) includes a model file (MF) for maintaining standard data for each vehicle model, and a library file (library file, LF) for maintaining deformation data according to the vehicle model. That is, as shown in Figure 3 is a schematic diagram of the data required for the wire harness design, the model file (MF) is to maintain the standard data of each of the A, B, C, and N vehicles, the library file (LF ) Maintains the deformation data of each of A, B, C and N vehicles.

As shown in FIG. 2B, all information about various vehicles is classified and managed by using the vehicle model management module 11 into total standard data and unique data for each vehicle model, so as to analyze a vehicle currently being produced or advance in developing a new vehicle. Can be used for review.

That is, in the case of analyzing the registered vehicle at present, the data stored in the vehicle model management module 11 is read and analyzed. When registering a new vehicle to be developed, first, the new vehicle model name is registered in the vehicle type data storage 112 of the vehicle type management module 11 as, for example, a P vehicle type. Subsequently, a database for a P model, which is a new vehicle, is constructed. For example, when the new vehicle is similar to the A model that is databased in the vehicle type data storage 112 of the vehicle management module 11, The base is set as vehicle A, the model file is stored in the vehicle type data storage 112p, and the variant of the selected vehicle type is set and stored in the library file to build a database for the new vehicle. The standard data among the data of the new P vehicle uses data constructed in the standard database. In this way, vehicle model management for a new new vehicle is made.

The power system table preparation module 12 plays a role of systematically preparing a power system table in consideration of the relationship between the overall load of the vehicle and a power source and a fuse. Although not shown in the drawing, in the power supply system creation module 12, all information of a power supply, a fuse, and a single item required for the power supply system of the wire harness is constructed as a database regardless of the vehicle type. Is built into the database.

Accordingly, as shown in FIG. 4, the power system table preparation module 12 supplies data on power systems such as power, fuses, and components required for the wire harness to the power system database as a whole standard of the vehicle management module 11. Manage from input from database. After managing the data required for the power supply system, the power supply name, fuse and unit name required for the new vehicle are set, and these are automatically arranged. Subsequently, a consumption current, for example, a continuous current, a maximum current, or the like is calculated, an appropriate fuse capacity is calculated accordingly, a connection relationship is set by the connection relationship database, and a power supply system table is automatically created.

In the above, when setting the power source name, the power source name necessary for the wire harness is finally set by correcting, inserting a new power source name, or deleting an unnecessary power source name among power source names registered in the power system database.

When setting the fuse name, the name of the fuse currently registered in the power system database is changed, a new fuse name is required, or an unnecessary fuse name is deleted to finally set the fuse name required for the wire harness. At this time, when the fuse name is registered, the fuse argument is also registered in the database. The fuse argument is a fuse larger than the actually calculated fuse in order to allow an adequate margin when calculating the appropriate fuse capacity. The fuse argument is registered as 1.3 (130%) if the user wants a margin of 30%.

When setting the part name, the part name necessary for the wire harness is finally set by modifying, inserting a new required part name, or deleting an unnecessary part name from the current round item name from the power system database. When setting the unit name, the current classification is included with the unit name. Current for each unit is displayed as continuous and intermittent. At this time, the current classification has an important influence in determining the proper fuse capacity when preparing the final power supply design table, so the designer must clarify the current classification for each unit.

Therefore, when inserting a part name, it is necessary to input the part name and the current classification thereof. If the part name is to be modified, the part name or the current classification may be modified or the part name and the current classification thereof may be modified at the same time.

After setting the unit name, fuse name, and power name as described above, a power supply system table is prepared. First, the relationship between the power source and the fuse is set. At this time, the relationship between the power source and the fuse is limited to the vehicle type currently being worked on, since the vehicle has its own power system and does not affect the relationship setting of other vehicle types.

After establishing the relationship between the power source and the fuse, a connection relationship is made and a connection relationship between the power source or the fuse and a single component is made. At this time, the relationship between the power source and the fuse can be deleted or modified as described above, and the connection relationship between the power source or the fuse and the single unit can also be deleted or modified.

When the power scheme is automatically generated using the power scheme table creation module 12 in the above-described manner, it is possible to automatically generate a current value, an appropriate fuse capacity, etc. in a short time as compared with the conventional method by manual labor. It is possible to automatically arrange the power supply, fuse and unit, so that the automatic operation of the power system table is possible. As a result, designers' errors can be minimized and productivity can be increased, and the drawing standardization and preparation time of power system tables can be shortened.

Referring to FIG. 5, a method of creating an electrical symbol required for a wire harness through the electric symbol preparing module 13 may include creating an electrical symbol, selecting a function, and inputting a name of the electrical symbol and a keyword necessary for storing a library. Select a group of electrical symbols to create from the symbol attribute panel, draw the selected symbol and save it in the corresponding library.

When importing an existing symbol stored in the electric symbol library, select the group to which the electric symbol to be imported belongs and select the symbol name from the selected group. In addition, when the existing symbol stored in the electric symbol library is to be deleted, the group to which the electric symbol to be deleted belongs is selected, and the electric symbol to be deleted is selected from among the electric symbols of the selected group.

The method for creating a single circuit diagram using the single circuit diagram preparation module is similar to the method for preparing an electrical symbol described above, and creates a single circuit diagram using the created electrical symbols. To create a new single circuit diagram, create a single circuit diagram, select a function, select a single circuit diagram from the single-circuit schematic attribute panel, enter the required electrical symbols from the electrical symbol library, construct a symbol, and declare a single connector. Next, it is stored in the corresponding library in the circuit diagram preparation module 14. When connecting parts, the designer connects the connectors made on the single circuit diagram with the appropriate wire. All information necessary for this wire can be entered, for example, line number, wire diameter, line color and line type.

Referring to FIG. 7, the system circuit diagram preparation module 15 inputs a unit circuit diagram from the unit circuit diagram creation module 14 and a power system table from the power scheme table module 12, arranges the system diagram according to the system diagram, and then supplies the necessary components. Select the connector of the circuit diagram and input all the information related to the unit circuit diagram and then connect it. First, input the number of the wire to be connected and check whether the number of the input wire is repeated.

If a duplicate wire number is not input, the wire property is input. If the wiring operation is completed, the system diagram is saved. If the wire number is not completed, the wiring operation is performed again. On the other hand, if the wire number to be wired is duplicated, it is determined whether it is a branch. If it is determined as a branch, the wire property of the branch is input to perform a subsequent operation, and the branch is In other words, if the wire number to be wired is duplicated, another wire number is input again.

The system circuit diagram completed in the above manner can be expanded or reduced if the system circuit diagram is not properly sized. For example, if the length of the power line and the ground line does not match the size of the completed system circuit diagram, it is possible to change the length of the power line and the ground line to an appropriate length.

In addition, it is possible to modify the system circuit diagram already created and stored in the system circuit diagram preparation module 15, or to delete a single circuit diagram on the system circuit diagram. That is, in the case where the system circuit diagram already prepared and stored in the system circuit diagram preparation module 15 is to be modified, the system circuit diagram to be modified is selected from the system circuit diagrams stored in the corresponding library of the system circuit diagram preparation module 15. Read in and make the correction.

When the unnecessary single circuit diagram on the system circuit diagram is deleted or a single circuit diagram incorrectly selected at the time of deletion is deleted, the single circuit diagram to be deleted on the system circuit diagram is selected and deleted. At this time, if the disconnected single circuit diagram and other single circuit diagrams on the system circuit diagram are connected, all wiring related to the deleted single circuit diagram must be deleted to prevent abnormality of the turnover system on the circuit diagram.

In addition, it is not only possible to search the wiring information on the system circuit diagram, that is, the information about the path and the wiring of the connected wires, but also change the properties of the wiring. That is, information on the connector used, information on the route and wiring of the wire connected, for example, the name of the unit at the start point, the connector, the name of the terminal at the end point, the connector, the terminal name, and the line number, wire color, wire diameter and It is possible to search for a Zen species.

Therefore, even if an abnormality occurs in the numbering system, errors in the numbering system can be eliminated by reconstructing the database related to the connection by searching the wirings in all the system circuit diagrams currently stored in the system schematic drawing module 15.

When the electric symbol is created through the electric symbol preparation module 13 as described above, a single circuit diagram is created using the created electrical symbols, and a single circuit diagram is arranged to create a system circuit diagram, as well as wire information, In other words, information about wire diameter, color, type and line number can be built as a database, power, fuse, and single item database of the already established power system table can be used, and the wiring diagram and wire related information can be automated. have.

Therefore, by using the electric symbol preparation module 13, by creating the electric symbol and automatically stored in the library, it is possible to prevent a mistake and to obtain convenience and reduction in operation. When creating a circuit diagram, each unit is given a characteristic to a separate library, and information on the connectors used and the connected wires are managed to prevent duplication of line numbers and the use of undeveloped wires. It is very useful when using, and the circuit diagram can be simplified.

Therefore, it is possible to secure the reliability of the wiring information of the circuit diagram, and to minimize the loss due to the man-hour and design deformation of the circuit diagram design.

Referring to FIG. 8, a method of creating a comprehensive circuit diagram using the integrated circuit diagram preparation module 16 is similar to the system circuit diagram creation method of FIG. 7. First, the system diagram required for the wire harness of the new vehicle is input from the corresponding library of the system circuit diagram preparation module 15, and the input system diagram is arranged and then connected. First, input the wire number and the wire property in order to create a comprehensive circuit diagram when all wiring is completed. When the wire number is duplicated when the wire number is input, the wire property is input in the case of the wire branch, and the wire number is input again when the wire number is not the branch of the wire.

When the preparation of the comprehensive circuit diagram is completed, the connection list can be prepared by the connection on the comprehensive circuit diagram, and the modification of the comprehensive circuit diagram stored in the corresponding library of the integrated circuit diagram preparation module 16 can be performed as in the case of the system diagram above. .

When a comprehensive circuit diagram is created using the comprehensive circuit diagram preparation module 16, the circuit diagram is easy to prepare, and the effects of the reduction of airborne and design error prevention due to shortening of the design and design verification time can be expected.

Referring to FIG. 9, the path design module 17 inputs a comprehensive circuit diagram from the comprehensive circuit diagram preparation module 16, automatically calculates a bundle thickness using the inputted comprehensive circuit diagram data, and calculates the length of the layout. Various information such as branch position is calculated. Then, the layout of the wire harness is completed using the calculated information, and data such as length information thereof is stored.

Conventionally, the wire harness layout is input to the CAD by the thickness of the bundle, or the layout optimization is attempted in a white-body state. However, by using the path design module 17 as described above, the interference of the layout of the wire harness is determined. It is possible to design wire harness precisely by calculating accurate information about length and branch position by checking, thus minimizing the number of optimization of wire harness layout, and saving considerable labor.

Referring to FIG. 10, the assembly design module 18 inputs data on the comprehensive circuit diagram from the comprehensive circuit diagram preparation module 16 and data on the route design from the route design module 17, and uses the input data to display the assembly diagram. Automatically create and record the wiring list automatically.

Therefore, the assembly design module is created based on various data on the comprehensive circuit diagram and path design. Therefore, it prevents design error and shortens the design and design verification time. And it can be aggregated to accurately predict the required parts and costs in advance, and can provide information on the subsequent process can contribute to shorten the delivery time and improve product quality.

Referring to FIG. 11, the evaluation support module 19 inputs data on path design from the path design module 17 and assembly data from the assembly design module 18 to collect information for each step for wire harness design evaluation. The list of evaluations by category, item or type was automatically generated.

By using the evaluation support module 19, it is easier and faster to create an evaluation list for a design, which enables accurate cost calculation and design evaluation, and thus can be used for an analysis of the current vehicle and advance review when developing a new vehicle. In addition, the standardization of drawings and the productivity of drawing work can be greatly improved.
