Description

Composite cable, composite harness, and vehicle

The present invention relates to a composite cable, a composite harness, and a vehicle, and more particularly to a composite cable, a composite harness, and a vehicle that connect a wheel side and a vehicle body side in a vehicle such as an automobile.

In recent years, electric braking devices have been used in vehicles such as automobiles.

Electromechanical brakes (Electro-Mechanical Brake, EMB) and electric parking brakes (Electric Parking Brake, EPB) are known as electric braking devices.

The electromechanical brake is also simply called an electric brake or an electric brake, and a dedicated electric motor provided on each wheel of the vehicle according to the amount of operation (stepping force or displacement) of the brake pedal by the driver. The brake driving force is controlled by the piston driven by the electric motor and the brake pad is pressed against the disc rotor of the wheel to generate a braking force according to the driver's intention.

In the electric parking brake, the driver operates a parking brake operation switch after the vehicle is stopped to drive a dedicated electric motor provided on each wheel of the vehicle, and a brake pad is driven by a piston driven by the electric motor. Is pressed against the disc rotor of the wheel to generate a braking force.

Further, in recent vehicles, sensors such as an ABS (Anti-lock Brake する System) sensor that detects the rotational speed of a running wheel, an air pressure sensor that detects tire air pressure, and a temperature sensor are mounted on the wheel. There are many cases.

Therefore, the signal line for the sensor mounted on the wheel and the signal line for controlling the electromechanical brake and the power line for supplying electric power to the electric motor for the electromechanical brake and the electric parking brake are used as a common sheath. The wheel side and the vehicle body side are connected using the accommodated composite cable. The composite cable in which the connector is integrally provided is called a composite harness.

In the composite cable, since the power supply line and the signal line are accommodated in a common sheath, there is a possibility that electromagnetic noise due to the current flowing through the power supply line may occur. Therefore, a composite cable using a signal line covered with a shield member has been proposed as a countermeasure against electromagnetic wave noise (see, for example, Patent Document 1).

JP 2005-166450 A

However, in the above-described conventional composite cable, when the power supply line is used for an application in which a large current flows, the influence of electromagnetic wave noise becomes very large. There is a problem that the cost may be increased. The increase in the size of the shield member leads to an increase in the diameter of the entire composite cable, which also contributes to a decrease in the layout of the composite cable.

For example, a power line that supplies power to an electric motor for an electromechanical brake frequently causes a relatively large drive current to flow while the vehicle is running, so that the influence of electromagnetic noise is reduced without increasing the diameter. There is a demand for a composite cable that can be used.

Therefore, an object of the present invention is to provide a composite cable, a composite harness, and a vehicle that can solve the above-described problems and can reduce the influence of electromagnetic noise while suppressing an increase in diameter.

The present invention has been devised to achieve the above object, and includes at least one signal line for transmitting an electrical signal, at least one pair of first power supply lines for supplying power, the signal line, and the first line. A sheath that collectively covers one power line, and a linear body that is disposed between the signal line and the first power line and separates the signal line and the first power line, The linear body is a composite cable including a second power supply line that supplies a drive current to an electric motor of an electric parking brake that generates a braking force after the vehicle stops, or a dummy line that is not used for signal transmission and power transmission. is there.

Moreover, this invention is a composite harness provided with the said composite cable and the connector attached to at least any one edge part among the edge parts of the said signal wire | line and the said 1st power supply line.
Moreover, this invention is a vehicle which connected the wheel side and the vehicle body side using the said composite cable.

According to the present invention, it is possible to provide a composite cable, a composite harness, and a vehicle that can reduce the influence of electromagnetic noise while suppressing an increase in diameter.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a configuration of a vehicle using the composite cable according to the present embodiment.

As shown in FIG. 1, the vehicle 100 is provided with an electromechanical brake (hereinafter referred to as EMB) 11 and an electric parking brake (hereinafter referred to as EPB) 12 as electric braking devices.

The EMB 11 includes an EMB electric motor 11a, an EMB control device 11b, and an EMB control unit 11c.

The EMB electric motor 11 a and the EMB control device 11 b are mounted on the wheels 16 of the vehicle 100. The EMB control unit 11 c is mounted on an electronic control unit (hereinafter referred to as ECU) 15 of the vehicle 100. The ECU 15 is mounted on the vehicle body 14 of the vehicle 100 and performs various controls including the control of the internal combustion engine of the vehicle 100. The EMB control unit 11c may be mounted on a control unit other than the ECU 15, or may be mounted on a dedicated hardware unit.

Although not shown, the EMB electric motor 11a is provided with a piston to which a brake pad is attached. By moving the piston by the rotational drive of the EMB electric motor 11a, the brake pad of the wheel 16 is moved. It is configured to generate a braking force by pressing against the disc rotor of the wheel. A pair of first power supply lines 2 is connected to the EMB electric motor 11a as a power supply line for supplying a drive current to the EMB electric motor 11a. The first power supply line 2 is a specific example of the first power supply line of the present invention.

The EMB control device 11b controls the EMB electric motor 11a according to a control signal from the EMB control unit 11c, and detects a failure of the EMB electric motor 11a. The EMB control device 11b and the EMB control unit 11c are connected by a CAN (Controller Area Network), and are configured to perform communication between the EMB control device 11b and the EMB control unit 11c. The control signal line (here, CAN cable) 4 connected to the EMB control device 11b is a specific example of the signal line of the present invention.

The EMB control unit 11c rotates the EMB electric motor 11a via the EMB control device 11b in response to an output signal from the brake pedal sensor 11d that detects an operation amount (stepping force or displacement amount) of the brake pedal of the vehicle 100. It is configured to control the force and generate a braking force on the wheel 16 according to the driver's intention.

The EPB 12 includes an EPB electric motor 12a and an EPB control unit 12b.

The electric motor 12a for EPB is mounted on the wheel 16 of the vehicle 100. The EPB control unit 12 b is mounted on the ECU 15 of the vehicle 100. The EPB control unit 12b may be mounted on a control unit other than the ECU 15, or may be mounted on a dedicated hardware unit.

Although not shown, the EPB electric motor 12a is provided with a piston to which a brake pad is attached, and the brake pad is moved by rotating the EPB electric motor 12a to move the brake pad to the wheel 16 of the wheel 16. The disc rotor is pressed to generate a braking force. A pair of second power supply lines 3 is connected to the EPB electric motor 12a as a power supply line for supplying a drive current to the EPB electric motor 12a. The second power supply line 3 is a specific example of the linear body of the present invention.

When the parking brake operation switch 12c is operated from the off state to the on state when the vehicle 100 is stopped, the EPB control unit 12b outputs a drive current to the EPB electric motor 12a for a predetermined time (for example, 1 second). The brake pad is pressed against the disk rotor of the wheel 16 to generate a braking force on the wheel 16. Further, the EPB controller 12b outputs a drive current to the EPB electric motor 12a when the parking brake operation switch 12c is operated from the on state to the off state, or when the accelerator pedal is depressed. The pad is configured to be separated from the disc rotor of the wheel to release the braking force to the wheel 16. That is, the operation state of the EPB 12 is configured to be maintained after the parking brake operation switch 12c is turned on until the parking brake operation switch 12c is turned off or the accelerator pedal is depressed. The parking brake operation switch 12c may be a lever type or pedal type switch.

The composite cable 1 according to the present embodiment is obtained by collectively covering the

power supply lines

2 and 3 and the signal line 4 with the sheath 10 (see FIG. 2). The composite cable 1 extended from the wheel 16 side is connected to an electric wire group 19 in a relay box 18 provided on the vehicle body 14, and is connected to an ECU 15 and a battery (not shown) via the electric wire group 19. Yes.

In FIG. 1, only one wheel 16 is shown for simplification of the drawing, but the EMB electric motor 11 a, the EMB control device 11 b, and the EPB electric motor 12 a are mounted on each wheel 16 of the vehicle 100. For example, the vehicle 100 may be mounted only on the front wheels or only on the rear wheels.

Next, the composite cable 1 according to this embodiment will be described.

FIG. 2 is a cross-sectional view of the composite cable 1 according to the present embodiment.

As shown in FIG. 2, the composite cable 1 includes at least one (here, one) signal line 4 for transmitting an electrical signal and at least one pair (here, one pair) of first power supply lines for supplying power. 2 and a sheath 10 that collectively covers the signal line 4 and the first power supply line 2.

In the present embodiment, the composite cable 1 includes a pair of first power supply lines 2 connected to the EMB electric motor 11a and a signal line 4 connected to the EMB control device 11b, and the wheel 16 side. The vehicle body 14 side is configured to be connected.

The first power supply line 2 is composed of an insulated wire in which a central conductor 20 obtained by twisting highly conductive strands such as copper is covered with an insulator 21 made of an insulating resin. What is necessary is just to set suitably the outer diameter of the center conductor 20 of the 1st power supply line 2, and the thickness of the insulator 21 according to the magnitude | size of the drive current requested | required.

The signal line 4 is configured by covering a well-conductive central conductor 41 such as copper with an insulator 42 made of an insulating resin such as cross-linked polyethylene, and has two electric wires 40 that transmit electric signals, A shield member 45 is provided around a twisted pair wire 43 obtained by twisting these two electric wires 40 together. The shield member 45 is provided on the outermost layer of the signal line 4. Although the case where the signal line 4 is an EMB control signal line will be described here, it may be a sensor signal line mounted on the wheel 16 of the vehicle 100.

When the shield member 45 is provided directly around the twisted pair wire 43, the shield member 45 enters the recess between the two electric wires 40, and when the composite cable 1 is repeatedly bent, one of the shield members 45 is provided. An excessive load may be applied to the part, and the shield member 45 may be damaged.

Therefore, in the present embodiment, by providing the inclusion 44 between the twisted pair wire 43 and the shield member 45, the shield member 45 is prevented from entering the recess between the two electric wires 40, and is flex-resistant. Has improved. As the inclusions 44, fiber bodies such as polypropylene yarns, aramid fibers, nylon fibers, or fiber plastics that are generally used as cable inclusions, paper, or cotton yarn can be used.

The specific configuration of the signal line 4 is not limited to this. For example, the inclusion 44 is omitted, the twisted pair wire 43 is covered with an insulator, and the shield member 45 is provided around the insulator. You may comprise. However, in this case, since the entire twisted pair wire 43 needs to be covered with an insulator in terms of manufacturing method, the outer diameter of the signal wire 4 is slightly increased. When the inclusion 44 is used as in the present embodiment, it is only necessary to arrange the inclusion 44 so as to fill the recess between the two electric wires 40, so that the outer diameter of the signal line 4 is increased. And the increase in diameter of the entire composite cable 1 can be suppressed.

Now, the composite cable 1 according to the present embodiment further includes a linear body 200 that is disposed between the signal line 4 and the first power supply line 2 and separates the signal line 4 and the first power supply line 2. Yes.

In the present embodiment, a pair of second power supply lines 3 for supplying a drive current to the EPB electric motor 12a is used as the linear body 200. The 2nd power wire 3 consists of an insulated wire which coat | covered the center conductor 30 which twisted together the highly conductive strands, such as copper, with the insulator 31 which consists of insulating resin.

The EPB 12 is used only for a short time while the vehicle is stopped, and can be used as the linear body 200 because the influence of electromagnetic noise caused by the drive current flowing through the second power supply line 3 is relatively small. In addition, the linear body 200 is not limited to the 2nd power supply line 3, For example, you may use the dummy line which is not used for signal transmission and electric power transmission. In addition, as a dummy wire, what consists only of resin which abbreviate | omitted the center conductor as well as the insulated wire which coat | covered the insulator with the center conductor can be used.

The signal line 4 and the

power supply lines

2 and 3 are spirally wound and twisted together. The form in which the signal line 4 and the

power supply lines

2 and 3 are twisted is not limited to this, and for example, a so-called SZ twist in which the twisting direction is periodically reversed may be employed.

In the present embodiment, the surface of the linear body 200, that is, the insulator 31 of the second power supply line 3 comes into direct contact with the shield member 45 of the signal line 4. Therefore, in order to suppress wear of the shield member 45, it is desirable that the insulator 31 is made of a material that is as slippery as possible (having a small friction coefficient). Examples of the material used for the insulator 31 include a fluororesin such as ETFE (ethylene-tetrafluoroethylene copolymer).

Further, a lubricant for reducing frictional resistance and improving lubricity may be disposed between the signal line 4 and the second power supply line 3 so as to suppress wear of the shield member 45. . As the lubricant, for example, talc (Mg ₃ Si ₄ O ₁₀ (OH) ₂ ) or silica (SiO ₂ ) can be used.

Furthermore, a first separator member (not shown) is provided around the signal line 4 to prevent the signal line 4 from coming into direct contact with surrounding members so that the wear of the shield member 45 is suppressed. It may be configured. The first separator member is configured, for example, by winding paper around the outer periphery of the signal line 4. Although the paper wound around the outer periphery of the signal line 4 may be torn apart due to the bending of the composite cable 1, the finely torn paper also serves as a cushioning material and contributes to the suppression of wear of the shield member 45. Will do.

The composite cable 1 further includes a collective shield member 9 that collectively covers the signal line 4, the first power supply line 2, and the second power supply line 3, and is configured to cover the sheath 10 around the collective shield member 9. Has been.

When the collective shield member 9 is provided directly around the signal line 4 and the

power supply lines

2 and 3, the collective shield member 9 and the shield member 45 of the signal line 4 come into contact with each other and wear occurs. Therefore, in the present embodiment, the second shield member 9 is separated from the collective shield member 9 and the signal line 4 and the

power supply lines

2 and 3 by the second for separating the collective shield member 9 from the signal line 4 and the

power supply lines

2 and 3. A separator member 8 is provided. For example, paper can be used as the second separator member 8.

The inclusions 7 are filled in the second separator member 8. By providing the inclusion 7, the outer shape of the sheath 10 in a cross section perpendicular to the central axis of the composite cable 1 is made close to a circular shape, that is, the circularity of the composite cable 1 is further improved, and the routeability of the composite cable 1 is improved. It becomes possible to improve further.

As the inclusions 7, fiber bodies such as polypropylene yarns, aramid fibers, nylon fibers, or fiber-based plastics that are generally used as cable inclusions, paper, or cotton yarn can be used. Then, the inclusion 7 contains artificial polypeptide fibers. This artificial polypeptide fiber is also called a spider silk fiber, and is an artificial fiber containing a polypeptide derived from a natural spider silk protein as a main component. By including the artificial polypeptide fiber in the inclusion 7, the strength of the composite cable 1 can be increased.

As the collective shield member 9, for example, a braided shield obtained by braiding a plurality of highly conductive wires such as copper in a lattice shape can be used. In the present embodiment, as shown in FIG. 3, as the collective shield member 9, a plurality of highly conductive strands 61 such as copper and artificial polypeptide fibers (artificial spider fiber) 62 are “predetermined ratio”. A braided shield with artificial spider fiber mixed together in a grid pattern was used. Here, the “predetermined ratio” is a ratio that does not lose the original shielding function. By using an artificial spider silk fiber mixed braided shield as the collective shield member 9, the collective shield member 9 can be reduced in weight.

Here, the case where an artificial spider fiber-mixed braided shield is used as the collective shield member 9 is described. And a laminated braided shield obtained by laminating artificial spider silk braided layers in which artificial polypeptide fibers 62 are knitted in a lattice shape.

As the sheath 10, a sheath made of a flexible polyurethane excellent in flexibility and durability can be suitably used. The sheath 10 may contain artificial polypeptide fibers. Since the strength is increased by including the artificial polypeptide fiber, the sheath 10 can be thinned by adding the artificial polypeptide fiber to the sheath 10, and the flexibility can be maintained while maintaining the strength of the composite cable 1. It is possible to increase the weight and reduce the weight.

Next, the composite harness according to this embodiment will be described.

FIG. 4 is a schematic configuration diagram of the composite harness according to the present embodiment.

As shown in FIG. 4, the composite harness 60 includes a composite cable 1 according to the present embodiment, a connector attached to at least one of the end portions of the signal line 4 and the

power supply lines

2 and 3. , And is configured.

4, the left side in the drawing shows the end portion on the wheel 16 side, and the right side in the drawing shows the end portion on the vehicle body 14 side (on the relay box 18 side). In the following description, the end portion on the wheel 16 side of the composite harness 60 is referred to as “one end portion”, and the end portion on the vehicle body 14 side (relay box 18 side) is referred to as “other end portion”.

A wheel-side first power connector 61a for connection to the EMB electric motor 11a is attached to one end of the pair of first power lines 2, and the other end of the pair of first power lines 2 is attached to the other end of the pair of first power lines 2. A vehicle body side first power connector 61b for connection with the electric wire group 19 in the relay box 18 is attached.

A wheel-side second power connector 62a for connection to the EPB electric motor 12a is attached to one end of the pair of second power lines 3, and the other end of the pair of second power lines 3 is attached to the other end of the pair of second power lines 3. A vehicle body side second power connector 62b for connection to the wire group 19 in the relay box 18 is attached.

A wheel-side CAN connector 63a for connection to the EMB control device 11b is attached to one end of the signal line 4, and connection to the wire group 19 in the relay box 18 is connected to the other end of the signal line 4. A vehicle body side CAN connector 63b is attached.

Here, the case where the

power supply lines

2 and 3 and the signal line 4 are individually provided with the connectors has been described. However, a dedicated connector for connecting the

power supply lines

2 and 3 and the signal line 4 in a lump is provided. It doesn't matter.

As described above, in the composite cable 1 according to the present embodiment, the linear body 200 that separates the signal line 4 and the first power supply line 2 is disposed between the signal line 4 and the first power supply line 2. is doing.

By providing the linear body 200, the first power supply line 2 and the signal line 4 can be separated from each other, and the influence of electromagnetic noise caused by the current flowing through the first power supply line 2 can be reduced. . As a result, since a measure such as providing a large shield member 45 on the signal line 4 is not required, an increase in the diameter of the signal line 4 can be suppressed, and an increase in the overall diameter of the composite cable 1 can be suppressed. . That is, according to the present embodiment, it is possible to realize the composite cable 1 that can reduce the influence of electromagnetic noise while suppressing an increase in diameter.
