[0013] Hereinafter, one embodiment of the present invention will be described.

[0014] First, with reference to FIG. 1, a vehicle part layout consideration support system 100 according to an embodiment of the present invention will be described.

[0015] The vehicle part placement study support system 100 is used when a user studies the placement of parts to be mounted on a vehicle. For example, when a part is added or changed to a vehicle, the vehicle part placement study support system 100 lists candidate placement positions for the part, which the user can use as a reference when deciding the placement positions of the part. The part to be added or changed is specified, for example, by the user.

[0016] As shown in Fig. 1, vehicle part layout study support system 100 includes a computer 1, a database 2, and a supercomputer 3. Computer 1 is an example of an "information processing device" of the present invention, and supercomputer 3 is an example of a "high-speed information processing device" of the present invention. Database 2 stores three-dimensional shape data of parts mounted on a vehicle. That is, database 2 stores three-dimensional CAD data of a vehicle before parts are added or changed, and three-dimensional CAD data of parts to be added or changed.

[0017] The computer 1 is configured to instruct the supercomputer 3 to search for the placement positions of the vehicle parts in the mounting space in which the vehicle parts are mounted. An example of the mounting space is the engine compartment, and an example of the parts is the vehicle components housed in the engine compartment. The computer 1 is also configured to be able to set conditions for searching for the placement positions of the parts. Examples of the conditions include the part to be added or changed, the mounting space in which the part is mounted, the working space required when mounting the part, the range in which the part is allowed to move after mounting, the direction and order of movement when mounting the part, and the dimensions when dividing the mounting space into a lattice. The computer 1 has position and orientation information of each part of the vehicle, but does not have three-dimensional shape data of each part of the vehicle.

[0018] The computer 1 includes a calculation unit 1a, a storage unit 1b, an input / output unit 1c, and a communication unit 1d. The storage unit 1b stores a program for controlling the computer 1, and the like. The calculation unit 1a is configured to control the computer 1 by executing the program stored in the storage unit 1b. The input / output unit 1c is connected to an input device 11, a display device 12, and the like. The input device 11 is, for example, a keyboard and a mouse (not shown), and is provided to accept user operation input. The display device 12 is configured to be capable of displaying a vehicle to which parts have been added or changed, and the like. The communication unit 1d is provided to communicate with the database 2 and the supercomputer 3.

[0019] The supercomputer 3 is configured to be able to execute calculation processing at higher speeds than the computer 1. The supercomputer 3 is configured to execute a search for a placement position of a component in the mounting space when a search for a placement position of a component in the mounting space is instructed by the computer 1. When the computer 1 instructs the supercomputer 3 to search for a placement position of a component, the conditions set by the computer 1 are output to the supercomputer 3.

[0020] Specifically, the supercomputer 3 is configured to place a part at a predetermined position in the mounting space, and calculate the presence or absence and the degree of interference using the two-dimensional outer shape of the part at multiple locations in a predetermined direction (for example, the vehicle width direction) while taking into account the conditions set by the computer 1. The two-dimensional outer shape of the part at multiple locations in the predetermined direction may be obtained from the database 2 via the computer 1, or may be obtained directly from the database 2. Here, the computer 1 is configured to divide the mounting space into a lattice shape, and output the mounting space divided into a lattice shape to the supercomputer 3. The supercomputer 3 is configured to calculate the presence or absence and the degree of interference using the lattice occupied by the part when the part is placed in the mounting space.

[0021] In this way, by using two-dimensional outer shapes at multiple locations in a specified direction, it is possible to simplify calculations compared to fitting a three-dimensional outer shape into the mounting space. When interference is examined using two-dimensional outer shapes at multiple locations, if the degree of interference exceeds a specified value, it is difficult to place a component at that position, so the calculation is stopped and the position is excluded from the candidates for component placement positions. This prevents unnecessary calculations from being performed, making it possible to reduce the calculation load.

[0022] The supercomputer 3 is configured to repeatedly calculate the presence or absence and the degree of interference while shifting the positions of the components in the mounting space. That is, the mounting space is searched for arrangement positions without interference and arrangement positions where the degree of interference is less than a predetermined value. Thereafter, the supercomputer 3 is configured to output the arrangement positions without interference and arrangement positions where the degree of interference is less than a predetermined value to the computer 1 when the search is completed. Note that the reason that arrangement positions where the degree of interference is less than a predetermined value are output to the computer 1 in addition to the arrangement positions without interference is that if the degree of interference is less than the predetermined value, it may be possible to address the problem by changing the shape of the components, etc.

[0023] The computer 1 is configured to display on the display device 12 the mounting space in which the parts are arranged, using the arrangement positions input from the supercomputer 3 and the three-dimensional shape data input from the database 2. This allows the user to check the vehicle to which parts have been added or changed.

[0024] The computer 1 is configured to be able to rearrange the multiple placement positions input from the supercomputer 3 based on conditions. For example, the multiple placement positions are rearranged in order of least interference. This allows the user to easily select the placement position that he or she wishes to check.

[0025] The computer 1 is also configured to be able to instruct the supercomputer 3 to search for a wiring path of the wire harness in the mounting space. When a search for a wiring path of the wire harness is instructed, the type and thickness of the wire harness, the position of the connector to which the wire harness is connected, and the like are output from the computer 1 to the supercomputer 3. The supercomputer 3 is configured to execute a search for the wiring path of the wire harness in the mounting space when a search for the wiring path of the wire harness in the mounting space is instructed by the computer 1. The search for the wiring path of the wire harness in the supercomputer 3 is performed, for example, by using an existing publicly known program.

[0026] The supercomputer 3 is configured to output the search results of the wiring route to the computer 1. The computer 1 is configured to superimpose the wire harness on the mounting space in which the parts are arranged and display it on the display device 12. This allows the user to check the wire harness that has been routed in addition to the added or changed parts. The computer 1 has the wiring route and the type and thickness of the wire harness input from the supercomputer 3, but does not have three-dimensional shape data of the wire harness.

[0027] The computer 1 is also configured to be able to instruct the supercomputer 3 to analyze the mounting space in which the parts and wire harness are arranged, based on the arrangement positions of added or changed parts, the three-dimensional shape data in the database 2, and the wiring route of the wire harness. Examples of this analysis include stress analysis, heat conduction analysis, and fluid analysis. The supercomputer 3 is configured to execute the analysis of the mounting space when the analysis of the mounting space is instructed by the computer 1.

[0028] The supercomputer 3 is configured to output the analysis results of the mounting space to the computer 1. The computer 1 is configured to display the analysis results of the mounting space on the display device 12. In addition, when a plurality of mounting spaces are analyzed, the analysis results can be rearranged using conditions.

[0029] -An example of searching for component placement positions- Next, an example of a search for component placement positions in the supercomputer 3 will be described with reference to Figures 2 to 6. In this example, a case will be described in which interference between two components A and B as shown in Figure 2 is examined using two-dimensional external shapes at three locations in the vehicle width direction. Note that the mounting space is partitioned into a 6x6 grid when viewed from the vehicle width direction.

[0030] First, the position W0 of component A and the position W0 of component B are fitted into the 6×6 mounting space. An example of the combination pattern is shown in FIG. 3. In patterns 1 to 9 shown in FIG. 3, component B is placed above component A. For simplification, only patterns 1 to 9 out of the many patterns will be described below. Next, the position W1 of component A and the position W1 of component B are fitted into the 6×6 mounting space, and the result is shown in FIG. 4. Furthermore, the position W2 of component A and the position W2 of component B are fitted into the 6×6 mounting space, and the result is shown in FIG. 5.

[0031] Here, if a condition is set that a gap of one grid or more is required between parts A and B, patterns 2 to 7 are excluded from the candidates. That is, as shown in Fig. 6, patterns are narrowed down to patterns 1, 8, and 9. Furthermore, if it is desirable to have a smaller dimension in the vehicle's fore-and-aft direction (the left-right direction in Fig. 6), pattern 9 is determined to be optimal.

[0032] Thereafter, the parts A and B are offset in the vehicle width direction and the same processing is performed. For example, the parts A and B are moved relatively in the vehicle width direction so that the position W1 of the part B is located on the same plane as the position W0 of the part A, and the same processing is performed.

[0033] -effect- In this embodiment, as described above, the interference of the part to be added or changed is considered using two-dimensional external shapes at multiple locations in a predetermined direction, which simplifies the calculation compared to fitting a three-dimensional external shape into the mounting space. Furthermore, when considering the interference of the part to be added or changed, if the degree of interference exceeds a predetermined value, the calculation is interrupted and the position is excluded from the candidates for the placement position of the part, which reduces the calculation load. Therefore, it is possible to improve the efficiency of considering the placement position of the part to be added or changed.

[0034] Furthermore, in this embodiment, the computer 1 does not have three-dimensional shape data of each part of the vehicle, so that the memory of the computer 1 can be made lighter.

[0035] Furthermore, in this embodiment, by making it possible to display the wire harness that has been routed in addition to the added or changed parts, the user can consider the placement of the wire harness in addition to the parts.

[0036] Furthermore, in this embodiment, the analysis results of the mounting space in which the added or changed parts and wire harnesses are arranged can be displayed, allowing the user to check the performance of the mounting space.

[0037] Furthermore, in this embodiment, by making it possible to sort a plurality of placement positions, the user can easily select the placement position that he or she wishes to check.

[0038] Furthermore, in this embodiment, by outputting to the computer 1 placement positions where the degree of interference is less than a predetermined value, placement positions that can be accommodated by changing the shape of the component or the like can also be left as candidates.

[0039] Furthermore, in this embodiment, the working space required when mounting the component is set as a condition for searching for the placement position of the component, so that the placement position of the component can be considered while taking into account the workability when mounting the component.

[0040] Furthermore, in this embodiment, as a condition for searching for a component placement position, a range within which the component is allowed to move after it is mounted is set, so that the placement position of the component can be considered while taking into account the movement of the component after it is mounted.

[0041] Furthermore, in this embodiment, the direction and order of movement when mounting the component are set as conditions for searching for the placement position of the component, so that placement positions of the component that can be appropriately mounted can be set as candidates.

[0042] -Other embodiments- It should be noted that the embodiments disclosed herein are illustrative in all respects and are not intended to be limiting. Therefore, the technical scope of the present invention is not interpreted solely by the above-described embodiments, but is defined by the claims. The technical scope of the present invention includes all modifications within the scope and meaning equivalent to the claims.

[0043] For example, in the above embodiment, an example has been shown in which the search for the placement positions of the components, the search for the wiring path of the wire harness, and the analysis of the mounting space in which the components are placed are executed by the supercomputer 3. However, without being limited to this, the search for the placement positions of the components, the search for the wiring path of the wire harness, and the analysis of the mounting space in which the components are placed may each be executed by a different supercomputer.

[0044] In the above embodiment, the placement positions of a plurality of components may be searched for simultaneously, or the placement position of each component may be searched for sequentially. [Industrial Applicability]
