Description

  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 components and wiring to the housing, 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 in which a signal line and a power line are separately arranged and an upper box frame for storing the signal line and the power line is provided. In Patent Document 3, three or more wiring connection portions are provided in one wiring member. In this case, when performing the wiring attachment / detachment work, there are many places where the wiring connection part is attached / detached, and the wiring routing is extensive and complicated, so that the wiring attachment / detachment work is not easy. Also, since the production of the wiring member requires a branching operation of the electric wire, the production of the wiring member is not easy, and it is easily affected by variations in work, and the quality of the wiring member is not always stable.

  Moreover, in patent document 3, although the space which accommodates a wiring member is touched, the accommodation method, for example, the fixing method and protection method of a wiring member are not touched. Actually, in order to fix and protect the wiring member, the wiring member is attached using a number of fixing frames, a sheet for protecting the wiring member, a fixing frame, a protective sheet, and a band for fixing the wiring member. Is spending a lot of work time. Moreover, suppression of electromagnetic waves generated from the wiring member is not taken into consideration, and there is a case where a problem of electromagnetic interference occurs and countermeasures must be taken.

  SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a vehicle control device capable of simplifying the assembly and removal work of the apparatus and rationalizing maintenance and inspection work for maintaining the performance of the apparatus for many years. .

  The vehicle control device according to the present invention includes a plurality of function modules and a signal line and a power line for connecting each function module. The function module includes an interface surface to which both the signal line and the power line are connected. Each interface surface is divided into a first interface region where a signal line terminal to which a signal line is connected is arranged and a second interface region where a power line terminal to which a power line is connected is arranged. The plurality of functional modules are arranged such that the first interface areas are aligned in the same direction and the second interface areas are aligned in the same direction, and signal lines and power lines interconnecting the functional modules are arranged. Are housed in a wire bundle housing section that cuts off electromagnetic noise installed along the interface surface.

  According to the vehicle control device of the present invention, the plurality of functional modules have interface surfaces to which both signal lines and power lines are connected, and each interface surface has signal line terminals to which signal lines are connected. It is divided into a first interface area to be arranged and a second interface area in which a power line terminal to which a power line is connected is arranged. In each functional module, the first interface areas are oriented in the same direction. The signal lines and power lines that interconnect each functional module are stored in a line bundle storage unit that blocks electromagnetic noise installed along the interface surface. As a result, the assembly and removal work of the equipment is simplified, and maintenance and inspection are performed to maintain the performance of the equipment for many years.

The function modules 4K, 4L, 4M, and 4N other than the function module 4E include second interface areas 6K, 6L, 6M, and 6N in which power line terminal groups are aggregated.

  Reference numeral 7 denotes a reactor, which is connected to the vehicle control device main body 2 via a terminal group 9. Reference numeral 31 denotes an electric motor, which is connected to the vehicle control device body 2 via the terminal groups 10a and 10b. Reference numeral 12 denotes a wire bundle housing portion (wiring duct) for housing a bundle of signal lines and power lines. 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.

  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.

  The main functions of each functional module will be described. The functional module 4K 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 4L has a voltage sensor, a current sensor, and the like as components, and has a function of monitoring the operation state of the voltage and current of the vehicle control device and a function of relaying the connection between the functional modules. The functional module 4N has a function of suppressing overvoltage by using a switching unit and a resistance as components. The functional module 4M has a function of converting a DC voltage into an AC voltage. The functional module 4E is a control circuit that has a control board and a relay circuit as components, and controls the entire vehicle control device in accordance with a signal sent from the host controller.

  FIG. 2 shows an interface surface 14 having the first interface region 5 and the second interface region 6 of each functional module 4 on the same surface. In the first interface area 5, signal line terminal groups 15 are aggregated, and in the second interface area 6, power line terminal groups 16 are aggregated. Further, the first interface area 5 and the second interface area 6 are physically separated by dotted lines as shown in FIG. This vertical relationship may be reversed, but the vertical relationship between the first interface region 5 and the second interface region 6 must be unified among all the functional modules constituting one device.

  That is, here, according to a unified design rule, each functional module has an interface surface including a first interface area in which signal line terminals are aggregated and a second interface area in which power line terminals are aggregated. Each interface surface has a first interface region commonly arranged on one end side and a second interface region commonly arranged on the other end side.

FIG. 3 shows a vehicle control device in which signal lines between the functional modules are connected to each other. Since the same applies to the power line, only the signal line will be described here.
As shown in FIG. 3, the signal line terminals aggregated in the first interface regions 5K, 5L, 5M, 5N, and 5E are connected to each other by the wiring member 18 having one connection terminal at each end. Here, the functional module 4E having a control circuit and the other functional modules 4K, 4L, 4M, and 4N are connected one-to-one.

  This wiring member 18 is accommodated in the wire bundle accommodating part 12 installed in the housing | casing (not shown) of a control apparatus along the interface surface 14 of each functional module. In FIG. 3, as an example, the wire bundle storage portions 12 are arranged in two rows on the lower surface of the housing, but the wire bundle storage portions 12 may be stacked vertically (in this case, the wiring member 18 is taken in and out from the side). In addition, it may be installed on the inside of the housing as appropriate in consideration of workability, such as installing on a plate with a gradient from the front to the back.

  FIG. 4 is a diagram showing the configuration of the wire bundle storage unit 12. The wire bundle storage unit 12 includes a frame 20 made of, for example, an iron-based metal material and a cylindrical protective sheet 21 made of an elastic material (for example, rubber) stored in the frame 20 in order to block electromagnetic noise. By storing the wiring members 18 that are not allowed to electromagnetic interference in different wire bundle storage portions 12, electromagnetic interference between the wiring members 18 can be effectively suppressed, and the effect of EMC countermeasures can be stably obtained. That is, the number of installed wire bundle storage units 12 may be appropriately determined according to the necessity of EMC countermeasures, and one is sufficient when there is no need for EMC countermeasures.

  Since the protective sheet 21 has a cut portion 23 over the entire length in order to put in and out the wiring member 18, the wiring member 18 accommodates a bundle of wires without using any special instrument at an arbitrary length at an arbitrary position. It can be stored in the part 12. The periphery of the cut portion 23 is thicker than the periphery because it is a portion where the wiring member 18 is taken in and out and durability is most required. Furthermore, it is good also as a shape which gave R inside so that the friction at the time of taking in / out of the wiring member 18 may decrease. Here, in order to make the inside of the protective sheet 21 in which the wiring member 18 is accommodated as wide as possible, it is substantially pentagonal, but this is not restrictive.

  The frame 20 is provided with a protruding portion 22, and after the wiring member 18 and the protective sheet 21 are accommodated in the frame 20, the protruding portion 22 is bent so that the protective sheet 21 and the wiring member 18 are pressed from above and fixed to the frame 20. Yes. It is assumed that the protruding portion 22 can be repeatedly bent.

  Further, as an example of the shape of the frame 20, an L-shaped frame 20a and a U-shaped frame 20b are conceivable as shown in the cross-sectional view of FIG. 5, but the protective sheet 21 and the wiring member 18 can be accommodated therein, and the control device It is not limited to this shape as long as it can be installed in the case.

  Furthermore, as shown in FIG. 6, the protective sheet 21 d is formed by combining the L-shaped frame 20 c and the U-shaped frame 20 d provided with a concave portion 24 on the outer upper portion of the protective sheet and provided with a convex portion that meshes with the concave portion 24. Since it is fixed to the frame, the protruding portion 22 is not required, the bending work is not required, and the wiring work is reduced.

  As described above, by storing the wiring member 18 in the wire bundle storage portion 12, the two functions for connecting the connection terminals provided at both ends of the wiring member 18 at the time of connection work for interconnecting the functional modules. Simply connecting to each signal line terminal 15 of the module and storing the wiring member 18 in the wire bundle storage portion 12, wiring work can be carried out easily. In addition, the one-to-one cable is simpler to route and easier to wire compared to a wiring member having three or more connection terminals that require branching of the wire. Therefore, the wiring member manufacturing operation is easy and hardly affected by variations in the operation, and the quality of the wiring member is always stable.

  Further, since the frame 20 made of a metal material has a function of suppressing electromagnetic interference, electromagnetic noise from the wiring member 18 that affects other devices can be suppressed. Furthermore, electromagnetic interference between the wiring members 18 can be effectively suppressed by providing a plurality of wire bundle storage portions 12 and storing the wiring members 18 in the different wire bundle storage portions 12, respectively. Of course, as the length of the portion of the wiring member 18 that is not accommodated in the wire bundle accommodating portion 12 is shorter, that is, the closer the wire bundle accommodating portion 12 is to the interface surface 14 of each functional module, the EMC countermeasure. The effect of can be stably obtained.

  As described above, according to the first embodiment, by providing the wire bundle storage portion 12 that fixes and stores the wiring member 18 in the housing of the vehicle control device, the wiring inside the device can be easily stored and fixed. Moreover, the wiring member 18 can be protected by the protective sheet 21. In addition, electromagnetic noise from the wiring member 18 that affects other devices can be suppressed, and electromagnetic interference between the wiring members 18 can also be effectively suppressed, and the effect of EMC countermeasures can be stably obtained. There is an effect that can be done.

Embodiment 2. FIG.
FIG. 7 is a block diagram showing a vehicle control apparatus according to Embodiment 2 of the present invention. In the figure, each of the functional modules 4K, 4L, 4M, 4P, and 4E has separated a first interface area in which signal line terminal groups are aggregated and a second interface area in which power line terminal groups are aggregated. The interface surface 14 has a plurality of functional modules divided into two groups. The interface surfaces 14 of each group are arranged adjacent to each other in the same direction, and each interface surface 14 of one group and each of the other groups are arranged. The interface surfaces 14 are arranged to face each other, and each interface surface 14 has a first interface region commonly disposed on one end side (the lower end side in the drawing) and a second interface region commonly disposed on the other end. It is arranged on the part side (upper end side in the figure). The functional module 4E has only a first interface area in which signal line terminal groups are integrated on the interface surface, and the first interface area is arranged on one end side (lower end side in the figure). Yes. In the second embodiment, the length of power lines and signal lines can be shortened by dividing a plurality of functional modules into two groups and arranging each interface surface of one group and each interface surface of the other group facing each other. effective.

  In FIG. 7, the input terminal group 3 is disposed on the upper left and right sides. The wire bundle storage unit 12 is divided into two groups along the interface surface 14 of each functional module, and is installed in a housing (not shown) of the control device. When the first interface region 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 wire bundle storage unit 12 having a function of storing the signal line installed on the bottom surface of the housing. The method of bundling and fixing signal lines can be simplified and reduced in cost, and when there are many signal lines or signal line bundles that are wiring members 18, the assembly work and maintenance of the apparatus can be performed by looking from the underside of the vehicle. Inspection work becomes easier.

  As described above, by arranging the interface surfaces 14 of the plurality of functional modules 4 in parallel, the signal lines and the power lines that connect the interface regions can be arranged on the same plane, and the wiring path is most simplified. In addition, the installation length of the wire bundle storage unit 12 is shortened, and the cost and weight can be reduced.

  Further, as can be understood from FIG. 7, the basic flow line of the operator who mechanically mounts or electrically connects the functional module 4 is defined as the left-right direction regardless of how the shape of the functional module 4 is different. This makes it possible to reduce the difficulty of the work itself and at the same time reduce the work process. Further, 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.

  As described above, according to the second embodiment, even when the interface surface 14 is divided into two groups, the connection work for interconnecting the functional modules is provided on the wiring member 18 as in the first embodiment. The connectors at both ends are connected to the signal line terminals 15 on the function module 4 side, and then the wiring member 18 is only housed in the wire bundle housing portion 12, and wiring work can be easily performed. Further, since the branching work of the wiring member 18 is not required, the connecting work for interconnecting the functional modules is easy, hardly affected by work variations, and always stable. Furthermore, the basic flow line can be set in the left-right direction, so that the difficulty level of the work itself can be lowered and the work process can be reduced.

  According to each embodiment mentioned above, the noise control performance is high and the stable vehicle control device can be obtained. It is possible to reduce the difficulty of the assembly work and at the same time reduce the work process. These effects can be made less dependent on the housing structure of the apparatus. Moreover, although it is necessary to maintain the function of the on-vehicle equipment for a long period of 10 years or longer, the necessary maintenance and inspection work can be efficiently performed. 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.
