  The present invention relates to a vehicular control device that is installed in a box shape, for example, under a floor or on a roof in order to supply electric power to a vehicle device or the like.

  For example, Patent Literature 1 and Patent Literature 3 disclose devices mounted in a box shape under the floor. Moreover, about the apparatus equipped with a box shape on a roof, it is disclosed by patent document 2, for example.

JP 2001-258263 A (FIG. 3) Japanese Unexamined Patent Publication No. 7-17396 (FIG. 3) JP-A-5-199601 (FIGS. 1 and 2)

  In the prior art of Patent Document 1, although the arrangement of the main components housed in the housing is described, the arrangement relationship of the signal lines and power lines to be electrically connected is hardly mentioned. In practice, in general, signal lines and power lines for connecting parts are routed indefinitely. Therefore, there is a problem that it is not easy to attach or remove parts to the casing, and there is a problem that maintenance and inspection are not easy. In addition, since the signal line and the power line are stretched, the electromagnetic noise path by the semiconductor switch is complicated, and there is a problem that it is difficult to select an electromagnetic compatibility (EMC) countermeasure component.

  As an improvement of these, there is Patent Document 3, which discloses a signal line and a power line separated from each other. FIG. 11 is a cross-sectional view of a conventional vehicle control device disclosed in Patent Document 3. As shown in FIG. Under the floor of the vehicle 30, an upper housing 31 is attached and fixed to a suspension leg 40 of a vehicle body, and a lower housing 32 is attached and fixed thereto. The lower housing 32 houses a built-in device unit 33 that is a main component of the control device. An inspection cover 34 is provided on one side surface of the lower housing 32 so as to be freely opened and closed. An inspection cover 35 is provided on the other side surface of the lower housing 32 so as to be freely opened and closed. On one side of the built-in device unit 33, there is a power line tightening member 36, and a power line 37 connected thereto is wired to the upper housing 31.

  On the other side of the built-in device unit 33, there is a signal line connector 38 for the device, and a signal line 39 connected thereto is wired to the upper housing 31. The power line 37 and the signal line 39 are arranged separately in the upper housing 31. Even in this Patent Document 3, when the built-in device unit 33 is attached or removed, it is necessary to work not only from one side but also from the other side, and it is not easy to install, remove, maintain and inspect. There was a problem, especially troublesome work during emergency repairs. Further, since the power line 37 is arranged on one side and the signal line 39 is arranged on the other side, the built-in device unit 33 is attached or detached from the bottom surface of the housing with poor workability. There was a problem that the work of attaching or removing 33 was not easy.

The maintenance and inspection work for maintaining the performance of the apparatus can be rationalized. In particular, the attachment and removal of the power line and the signal line connected to the functional module is an operation from one side, which can be rationalized. In addition, the first interface region of the interface surface of the functional module of the control circuit is disposed on the lower end side where the first interface regions of the interface surfaces of the other plurality of functional modules are disposed. Electromagnetic interference can be suppressed.

Embodiment 1 FIG.
Embodiment 1 of the present invention will be described with reference to FIGS. FIG. 1 is a block diagram showing a vehicle control apparatus according to the first embodiment. The figure also shows the division into several functional modules. First, the configuration of FIG. 1 will be described. Reference numeral 1 denotes an overhead line, 2 denotes a vehicle control device body, and the overhead line 1 (the overhead line side and the ground side) is connected via an input terminal group 3. 4A to 4E are function modules, and all the function modules 4A-4E include the first interface areas 5A-5E in which signal line terminal groups are aggregated, and the function modules 4A-4D other than the function modules 4E include A second interface region 6A-6D in which power line terminal groups are integrated is provided. Some terminals have symbols a, b, and c.

  Reference numeral 7 denotes a reactor, which is connected to the vehicle control device main body 2 via a terminal group 9. Reference numeral 8 denotes a transformer (insulation transformer), which is connected to the vehicle control device main body 2 via the terminal groups 10a and 10b. Reference numeral 11 denotes an output terminal group of the vehicle control device main body. Reference numeral 12 denotes a wire bundle storage unit (wiring duct) that stores a bundle of signal wires, and has a function of binding signal wires. Although not shown, 13 is a control input terminal group for transmitting and receiving information to and from a controller that controls the vehicle control device at a higher level.

  The main functions of each functional module will be described. The functional module 4A is a switching circuit having a function of electrically connecting and disconnecting from the overhead line 1 (in this case, a DC power source). The functional module 4B has a DC voltage charging / discharging function, and has a space in which equipment (for example, a core) capable of suppressing electromagnetic noise can be arranged as necessary. The functional module 4C has a function of converting a DC voltage into an AC voltage. The functional module 4D has an electrical connection and disconnection function with respect to a load connected to the output terminal group 11, and has a space in which a device (for example, a core) that can suppress electromagnetic noise can be arranged as necessary. Usually, the load includes a vehicle lighting device, an air conditioner, and the like. The functional module 4E is a control circuit that controls the entire vehicle control device in accordance with a signal sent from the host controller via the control input terminal group 13 using a control board and a relay circuit as components. This vehicle control device is used as an auxiliary power supply device, for example.

  FIG. 2 is a circuit configuration diagram of the vehicle control device of FIG. An example of division according to the function definitions of the function modules 4A to 4E is also shown. The main components will be described as the configuration requirements of each functional module 4. The switch 14 is associated with the functional module 4A. The functional module 4 </ b> B is a charge / discharge circuit, and includes a reverse blocking semiconductor switch 15, a charge resistor 16, a discharge switch 17, and a discharge resistor 18. The functional module 4 </ b> C is an inverter and includes a capacitor 19 and a switching circuit 20. The functional module 4D is a contactor 21 that opens and closes the power supplied to the load. Note that FIG. 2 does not show, for example, a voltage sensor or a current sensor.

  As described above, when the functions are divided according to the function definitions of the function modules 4A to 4E, the function module 4C collects devices that mainly generate electromagnetic noise, that is, inverters, and the function module 4B and the function module 4D include A noise filter function can be provided if necessary. Further, as shown in FIGS. 1 and 2, each functional module 4 is arranged, and the second interface area 6 of one functional module 4 and the second interface area 6 of another functional module 4 are connected by a power line. The number of power lines or the number of sets (for example, three-phase alternating current) that connect the functional modules 4 to each other is only one for the direct current with respect to the power lines other than the power lines that are equal to the potential on the overhead line side and the potential on the ground side. Alternatively, the functional module 4 can be designed to be the only set for polyphase alternating current. That is, for each functional module 4, the functional module 4 can be designed to have a single number input or a single set number input and a single number output or a single set number output.

  This will be explained with reference to FIG. 1. Except for the power line equal to the potential on the overhead line side and the potential on the ground side, that is, the overhead side terminal 3b-terminal 6Aa, the ground side terminal 3a-terminal 6Bc, and the ground side terminal 3a-terminal 6Ca are excluded. The power line, that is, the functional module 4B includes the input side terminal 9b-terminal 6Ba, the output side terminal 6Bb-terminal 6Cb, and the functional module 4C includes the input side terminal 6Bb-terminal 6Cb, the output side terminal 6Cc-terminal 10a, The function module 4D is a single number input or a single set number input for a plurality of function modules, such as the input side terminal 10b-terminal 6Da and the output side terminal 6Db-terminal 11, and the single number output or Single set output.

  As in the first embodiment, a plurality of functional modules are connected in this order to a functional module of a switching circuit, a functional module of a charge / discharge circuit, a functional module of an inverter, and a functional module of a contactor. Each functional module 4B, 4C, 4D has a single number input or a single set number input, and a single number output or a single set number output. In this way, electricity input from the overhead wire 1 flows in one direction between the function modules arranged in the vehicle auxiliary power supply device until it is output from the vehicle auxiliary power supply device. The wiring path of the power line can be shortened. In addition, when a problem occurs in a certain function of the vehicle control device, the function modules 4 that must be inspected or replaced can be limited to a limited number, and can be easily inspected or replaced in a short time. Can be recovered.

  In addition, the functional module 4C having an inverter mainly serving as a source of electromagnetic noise is connected only to the functional module 4D via the functional module 4B and the transformer 8, and is not connected to other functional modules. As a device, noise sources can be integrated into one, electromagnetic noise can be effectively suppressed, and noise occurrence locations can be easily identified, so that EMC countermeasures can be effectively implemented. When the functional module 4E of the control circuit is connected as shown in FIG. 1, it can be moved away from the functional module 4C that generates electromagnetic noise.

  Thus, the vehicle control device used as an auxiliary power supply device is divided into a functional module having an open / close circuit, a functional module having a charge / discharge circuit, a functional module having an inverter, and a functional module having a contactor. Therefore, maintenance and inspection can be separated according to function and can be carried out promptly, and equipment that mainly generates electromagnetic noise is integrated into the functional module having an inverter, and noise countermeasures can be easily implemented.

  FIG. 3 shows an interface surface 22 having the first interface region 5 and the second interface region 6 of one functional module 4 on the same surface. In the first interface area 5, signal line terminal groups are aggregated, and in the second interface area 6, power line terminal groups are aggregated. Reference numeral 51 denotes a signal line bundle, which is a wiring in the functional module 4. Further, as shown in FIG. 3, the first interface area 5 and the second interface area 6 are physically divided into upper and lower portions by dotted lines, and in FIG. 3, the first interface area is located on the lower end side. 5 and the second interface region 6 is arranged on the upper end side. This vertical relationship may be reversed, but the vertical relationship must be unified for all functional modules 4 (excluding functional modules 4E, 4I, and 4J, 4I and 4J will be described later). All functional modules (except for the functional module 4E) applied to the first embodiment are designed based on a unified design rule as shown in FIG.

  In other words, the pre-unified design rule of the first embodiment is that each functional module having a signal line terminal and a power line terminal has a first interface area in which the signal line terminals are aggregated and a power line terminal. It has an interface surface on one side that is separated from the aggregated second interface region. In addition, the interface surface in each functional module is arranged by arranging the first interface area on one end side in common with all the functional modules and arranging the second interface area on the other end side. is there. Here, this is called wiring pre-arrangement design.

  In each functional module, the interface surface having the first interface region and the interface surface having the second interface region do not necessarily have to be the same surface. For example, both the first interface region and the second interface region are present on one side surface of the functional module, but one of the regions is recessed, that is, the first interface region and the second interface region. The interface surface having the first and second interface regions may be a surface on one side of the functional module.

  Further, the interface surfaces do not necessarily have to be the same surface among the plurality of functional modules. However, the optimal arrangement of each interface area is when each of the first interface areas in each functional module is on the same plane and each of the second interface areas in each functional module is on the same plane. is there. In this case, the wiring path is simplified most, and the power line can be used at low cost and light weight by shortening the wiring length and simplifying the processing of the power line.

  FIG. 4 is a cross-sectional view of the vehicle control apparatus of the first embodiment. In FIG. 4, the interface surfaces 22 of the plurality of functional modules 4 are arranged adjacent to each other in the same direction, the first interface region is commonly arranged on one end side (the lower end side in the drawing), It is sectional drawing in the control apparatus for vehicles by which two interface area | regions are arrange | positioned in the other end part side (upper end part side in the figure) in common. In this case, it is a desirable mode in which the interface surfaces 22 of the plurality of functional modules 4 are the same surface. Each functional module 4 is mounted on or surrounded by a frame 52 of the functional module so that the functional module 4 can be attached and detached in units of each functional module 4 and is fixed to the casing 25 that houses the functional module with a bolt 53. .

  It is desirable from the viewpoint of work efficiency that the size (bolt diameter) of the bolt 53 and the size (bolt diameter) of the power line terminal bolt 54 (bolt diameter) are the same for mounting and removing the functional module 4. If it does in this way, at the time of attachment and detachment of the functional module 4, what is necessary is just to prepare a wrench of one kind size with respect to the bolt 54 for power line terminals, and the volt | bolt 53, and workability | operativity improves. Reference numeral 55 denotes a signal line terminal bolt or connector. Reference numeral 56 denotes a cooling fin for the functional module. Reference numeral 40 denotes a suspension leg of the vehicle control device for fixing to the vehicle body.

  According to this embodiment, the plurality of functional modules are arranged adjacent to each other with the interface surfaces facing in the same direction. There may be large and small gaps between the functional modules. Since it is constituted by a plurality of function modules 4 having interface surfaces 22 of design rules that are unified in advance, maintenance and inspection operations can be rationalized by integrating maintenance and inspection units by function. In other words, by arranging a plurality of functional modules so that the interface surface where the power line terminals and signal line terminals are aggregated faces in the same direction, the power lines and signal lines connected to the functional modules are attached and removed on one side, For example, the work is from one side. In FIG. 4, the inspection cover 57 is removed, and the work is performed from the inspection cover 57 side. Moreover, attachment and detachment of the functional module 4 to / from the vehicle control device housing can be performed from the side of the vehicle control device housing 25 having a large work space and good workability, and is rationalized. In FIG. 4, the power line and the signal line can be removed from one side, and the functional module 4 can be detached from the vehicle control device housing from the other side.

  In addition, since the first interface region 5 and the second interface region 6 are arranged separately, for example, vertically, electromagnetic interference between the signal line and the power line can be effectively suppressed, and the electromagnetic noise path is easy. Can be specified. That is, the EMC countermeasure effect can be obtained stably. Furthermore, since the number of power lines can be reduced, the work processes required for assembly, removal, maintenance, and inspection can be reduced.

  As can be seen from FIG. 1, the functional module 4E is a separate functional module 4E having an interface surface having a first interface area 5E and no second interface area. The first interface region 5E on the interface surface of the separate functional module 4E is the side where the first interface regions 5A-5D of the interface surfaces of the other functional modules 4A-4D are arranged (in this case, the lower end side) ) In common. In the functional module 4E, those that cause trouble in the sound operation of the entire apparatus when malfunctioning due to noise, such as a control circuit board and a relay, are gathered. As a result, the power line can be separated from the power line as much as possible, and noise countermeasures can be applied to the function module 4E.

  In this way, in the function module 4E, as in the case of the other function modules 4A-4D, assembly, removal, maintenance, and inspection work can be streamlined, and the first interface area 5E can be changed to other first modules. By arranging them on the same side as the interface regions 5A-5D, the effect of EMC countermeasures can be stably obtained.

  Further, as shown in FIG. 3, if the terminals having the same shape are used for the power line terminals constituting the second interface regions 6 of the plurality of functional modules 4, the second interface regions 6 of the respective functional modules 4 are connected to each other. The cable diameter as the power line to be used, or the width and thickness of the conductor bus bar can be unified.

  Here, the signal line corresponds to a control signal of the semiconductor switch element, a power supply signal of about 100 V or less, a relay output signal, wiring for transmitting / receiving the sensor input power supply or output signal, its wiring material, and the like. The power line is a wiring not included in the signal line and its wiring material.

Embodiment 2. FIG.
FIG. 5 is a block diagram showing a vehicle control apparatus according to the second embodiment. In particular, the addition of the function module 4 will be described. In each figure, the same numerals indicate the same or corresponding parts, and the description thereof is omitted. The same shall apply hereinafter.

  As an example of the function module to be added here, a function module 4F (battery charging circuit) having a function of charging a battery mounted on the vehicle and a DC voltage input from the overhead line 1 are stepped down to supply power to the function module 4E. A function module 4G (emergency power supply circuit) having a function and a function module 4H (DC step-down circuit) having a function of inputting the output voltage of the function module 4F to step down and supplying power to other on-vehicle equipment not shown. . The functional module 4G as an emergency power supply circuit functions when the battery voltage becomes lower than the rating.

  The functional module 4F may have any circuit configuration as long as it is an AC / DC conversion circuit that can convert an AC voltage, which is an output of the function module 4D, into a DC voltage necessary for charging the battery. The functional module 4G may have any circuit configuration as long as it is a DC / DC converter that can step down a high DC voltage input from the overhead line 1 to an appropriate low voltage that can be handled by the functional module 4E. Further, the functional module 4H may have any circuit configuration as long as it is a DC / DC conversion circuit capable of stepping down the DC voltage output from the function module 4F to a different DC voltage. In FIG. 5, 23 and 24 are terminal groups, 5F, 5G, and 5H are first interface areas, and 6F, 6G, and 6H are second interface areas.

  Even when the functional modules 4F, 4G, and 4H are added in this way, the configuration of the interface surface 22 of the other functional modules 4 is completely changed by applying the unified design rule of the first embodiment in the same manner. It is possible to easily add the function modules 4F, 4G, and 4H having new functions without doing so. That is, the structural design can be simplified when expanding the functions of the vehicle control device. Further, since the configuration of the original functional module 4 is not changed, the reliability of the functional module 4 is maintained as it is.

  By designing the functional modules so that they are functionally separated (non-interfering) from one another, maintenance in the event of equipment failure has caused problems without having to check or replace other functional modules By inspecting or replacing only the functional module, the device can be restored quickly.

  Since the manufacture of the vehicle control device casing and each functional module is functionally separated and can be performed independently, the device housing and each functional module can be manufactured in parallel. The production time (lead time) can be shortened. Similarly, the design of the device housing and each functional module are also functionally separated and can be implemented independently. Therefore, when changing the design of one functional module, the design of another functional module is designed. There is no change. The apparatus housing and each functional module can be designed in parallel, and the design time can be shortened. Furthermore, since the design of the device casing and each functional module can be performed independently, outsourcing of the design can be easily performed.

  FIG. 6 is an explanatory view showing the design and production time reduction of the vehicle control device. Conventionally, the function module 1, the function module 2, the function module 3, and the housing are designed and manufactured in series. However, in the embodiment, the function module 1, the function module 2, the function module 3, and the housing are separated. Since the design and production can be performed in parallel, the design and production time can be shortened.

  Since the auxiliary power supply for a vehicle according to the first embodiment is configured by a combination of functionally separated functional modules, when adding, deleting, or improving functional modules in response to a request from a vehicle operating company, There is no design change of other functional modules. Therefore, in the vehicle auxiliary power supply device, there are various combinations of functions for each product. However, the vehicle auxiliary power supply device can easily add, delete, and improve function modules according to the functions required for each product. Therefore, it is possible to easily cope with the diversity of requirements and rationalize the design change work. In addition, in the unlikely event that a part breaks down or maintenance parts are discontinued, only the relevant functional modules can be redesigned and replaced, reducing the risk of hindering vehicle operation. can do.

Embodiment 3 FIG.
FIG. 7 is a block diagram showing a vehicle control apparatus according to the third embodiment. In FIG. 5, all the functional modules 4A to 4H are arranged horizontally side by side. In FIG. 7, the functional modules 4 are divided into two groups and arranged in two upper and lower rows (or two rows in the horizontal direction).

  Each functional module 4 includes a first interface region 5 in which signal line terminal groups are aggregated on one end side, and a second interface region 6 in which power line terminal groups are aggregated on the other end side. Having one interface surface. The functional module 4E has an interface surface having only the first interface region 5 in which the signal line terminal group is concentrated on one end side. The interface surfaces of the rows are arranged in the same direction in common. On the interface surface, the first interface regions 5 of the columns are commonly arranged on the side between the columns, and the second interface regions 6 of the columns are commonly arranged on the opposite side of the columns. Between each column, signal line bundle storage portions 12 are arranged to store signal lines connected to the respective first interface regions 5. A power line connected to each second interface region 6 is disposed on the opposite side between the columns.

  As described above, when the first interface regions 5 of the columns are arranged in common between the columns, the signal line has a low voltage, so that the interval between the columns can be reduced. In addition, although each 1st interface area | region 5 of each row | line | column is arrange | positioned in common between each row | line | column, conversely, each 2nd interface area | region 6 of each row | line | column can also be arrange | positioned in common between each row | line | column. Is possible.

  According to the third embodiment, each row of the vehicle control device body 2 is configured by the plurality of functional modules 4 having the interface surface 22 of the design rule that is unified in advance, so that maintenance and inspection units are aggregated by function. In addition, since maintenance and inspection units can be confirmed from one side, maintenance and inspection work can be rationalized. Further, the first interface region 5 in each column and the second interface region 6 in each column are separately arranged between the columns and on the opposite side, so that electromagnetic interference between the signal line and the power line is effectively suppressed. be able to. Furthermore, since the number of power lines can be reduced, the work processes required for assembly, removal, maintenance, and inspection can be reduced.

Embodiment 4 FIG.
FIG. 8 is an external perspective view showing the vehicle control apparatus according to Embodiment 4 with the casing removed. In particular, the arrangement of functional modules having different shapes will be described more specifically. In the figure, each functional module has an interface surface 22 that separates a first interface region in which signal line terminal groups are aggregated and a second interface region in which power line terminal groups are aggregated, and includes a plurality of interface surfaces 22. The functional modules are divided into two groups, and the interface surfaces of each group are arranged adjacent to each other in the same direction, and each interface surface of one group and each interface surface of the other group are arranged facing each other. Each of the surfaces has a first interface region commonly disposed on one side (the lower end side in the figure) and a second interface region commonly disposed on the other side (the upper end side in the figure). The functional module 4E has only a first interface region in which signal line terminal groups are gathered on the interface surface, and the first interface region is arranged on one side (the lower end side in the drawing). By dividing the plurality of functional modules into two groups and arranging the interface surfaces of one group and the interface surfaces of the other group facing each other, the length of the power line and the signal line can be shortened.

  In FIG. 8, the input terminal group 3 and the output terminal group 11 are arranged on the right side in the figure, and the terminal groups 9, 10a, and 10b are arranged on the left side, and are arranged on the upper side. The wire bundle storage unit 12 is disposed on the lower side. When the first interface area is on the lower end side, there is no need to hang and fix the signal line, and it can be easily stored in the wiring duct having the function of bundling the signal lines installed on the bottom surface of the housing. Can be simplified and the cost can be reduced. When there are many signal wires or signal wire bundles, assembling, maintaining, and inspecting the device is facilitated by looking from the underside of the vehicle.

  Even when the functional modules 4 of various sizes are arranged, the interface surface 22 is parallel. FIG. 8 shows a case where the interface surfaces 22 of a plurality of functional modules 4 arranged in the lateral direction are flush with each other on each interface surface of one group and each interface surface of the other group. It is. However, even when the interface surfaces 22 of some of the functional modules 4 are displaced, as long as the interface surfaces 22 are parallel to each other, they do not deviate from the embodiment of the invention.

  As described above, the optimum arrangement of the interface areas is that each of the first interface areas in each functional module is on the same plane, and each of the second interface areas in each functional module is on the same plane. This is the case. In this case, the signal line and the power line connecting the interface regions can be arranged on the same plane, and the wiring route is simplified, and the wiring length is shortened and the processing of the power line is simplified. In addition, lightweight power lines can be used.

  As can be understood from FIG. 8, regardless of how the shape of the functional module 4 is different, the basic flow line of the operator who mechanically mounts or electrically connects the functional module 4 is the left-right direction. It is possible to reduce the difficulty level of the work itself and at the same time reduce the work process. Also, it is easy to confirm that the work has been performed reliably. For example, an operator who installs a bundle of signal wires, a so-called harness, can work without frequently raising and lowering the line of sight. In addition, electromagnetic interference between the power line and the signal line can be effectively suppressed in the same manner. Thus, even when the shape of the functional module 4 is different, the effect can be obtained in the same way.

  As shown in FIG. 8, by arranging the interface surfaces 22 of the plurality of functional modules 4 in parallel, the wiring duct-shaped wire bundle storage portion common to the signal lines connected to the first interface region 5 of each functional module 4 12 can be provided. As a result, the mounting state of the signal wire bundle, so-called harness, is hardly affected by work variations and is always stable. Therefore, the electromagnetic separation between the signal line and the power line outside the functional module 4 is ensured, and noise resistance is ensured. Can increase the sex.

  FIG. 9 is an external perspective view showing an apparatus for covering the actual vehicle by covering the functional module 4 shown in FIG. 8 in a box shape with the apparatus housing 25. Reference numeral 26 denotes an inspection cover. For example, when the inspection cover 26 is opened, it is possible to see the functional module 4 that needs to be inspected.

Embodiment 5 FIG.
FIG. 10 is a block diagram showing a vehicle control apparatus according to the fifth embodiment. FIG. 1 shows a configuration in which the reactor 7 and the transformer 8 separated from the apparatus main body are housed in the vehicle auxiliary power supply main body 2 in FIG. Even in such a case, each of the separate functional modules 4I and 4J constituting the reactor 7 and the transformer 8 has the second interface areas 6I and 6J in which the power line terminal groups are aggregated, and the first interface area. Each interface surface is aligned with the second interface regions 6A-6D of the other functional modules 4A-4D in common with one side (in the figure). It is arranged on the upper end side. In this way, a device can be manufactured without affecting the configuration and structure of the other functional modules 4A-4D.

  In this way, in the function modules 4I and 4J, as with the other function modules 4A to 4D, assembly, removal, maintenance, and inspection work can be rationalized, and the second interface areas 6I and 6J can be provided. By arranging in common on the same side as the other second interface regions 6A-6D, the effect of EMC countermeasures can be stably obtained.
