Description

  The present invention relates to an operation switch device for an on-vehicle electrical component, and more specifically, a so-called mechanical switch that switches a switching circuit by an operation such as pressing a switch button of an occupant for a switching operation of an electrical component mounted on an automobile, and a display screen It integrates a so-called soft switch that switches a switching circuit by electronic control by touching a key to provide an easy-to-use switch system.

  Recently, the number of electrical components mounted on automobiles has been increasing rapidly, and the number of switches for operating electrical components has increased accordingly. Many of these switches are so-called mechanical switches in which a passenger presses or rotates a switch button to switch a switching circuit. These mechanical switches are intensively mounted around the instrument panel, center console panel, and steering shaft within the reach of the driver. Therefore, it is difficult to arrange these mechanical switches in a place where they can be easily operated and in an order in which they can be easily operated, and there is a problem that the design is not clean. Furthermore, the wiring for connecting the mechanical switch and the electrical component is also increased, and both the weight of the mechanical switch itself and the wiring weight are increased to increase the weight and the cost.

  Therefore, in Japanese Patent No. 2883041 (Patent Document 1), an operation key part of an electrical component is displayed on a screen of a display device mounted on a vehicle, and the operation of the electrical component is controlled by operating the operation key unit. In the in-vehicle electrical component control apparatus, the display screen of the operation key part is grouped into a plurality according to the use frequency, the first screen displaying the operation key part with high use frequency, the operation key part with low use frequency being the second There has been proposed a display that is divided into screens after the above screen.

  Japanese Patent Laid-Open No. 2005-145305 (Patent Document 2) displaying a switch operation screen on the screen of the display device as in the above-mentioned Patent Document 1 discloses each electrical component based on a switching input signal by a switching operation button. Proposals have been made to sequentially display product switch operation screens.

  In each of the switch devices of Patent Documents 1 and 2, as shown in FIG. 6, the operation unit X of the display device in which a large number of signal lines and power lines W used for connection to the electrical components A to D are provided with the display screen Y. Will concentrate on. As a result, when the operation unit is mounted on an automobile, there are a large number of wires connected to the operation unit, which makes it difficult to secure a space for the connection unit and troublesome connection work. .

Japanese Patent No. 2883041 JP 2005-145305 A

  The present invention has been made in view of the above problems, and an object thereof is to solve a wiring problem that occurs when a large number of switch operation units display a screen.

In order to solve the above problems, the present invention provides:
A composite software switch operating means having a switch operation display screen for a plurality of electrical components;
A control box comprising a switching circuit, switching the switching circuit in accordance with an operation signal received from the composite soft switch operation means, and transmitting a switch control signal to the switch-operated electrical component;
With
There is provided an operation switch device for an on-vehicle electrical component, wherein the composite soft switch operation means and the control box are connected by a multiple communication line.

  As described above, the composite soft switch operation means having the switch operation display screen for controlling a plurality of electrical components is connected with a large number of signal lines for transmitting control signals to the electrical components, making wiring difficult. In the present invention, a multiple communication line is connected to the composite soft switch operating means, the multiple communication line is connected to a control box, and the control box is connected to each electrical component to be switched. Yes. In this way, if the signal communication line is changed to a multiplex communication line and a CAN communication line composed of a twisted pair electric line of a high line and a low line is used as the multiplex communication line, it can be configured with only two electric wires. Therefore, the connection between the composite software switch operating means and the control device is simplified, and the burden of the connection work during the assembly work can be reduced. In addition, the problem of space and the problem of weight increase can be solved, and it is possible to easily cope with a sudden increase in the number of electrical components operated by the composite soft switch operating means.

The electrical components displayed on the switch operation display screen may display functionally organized electrical components for each group, or group the electrical components according to the frequency of use as in Patent Document 1 and sequentially display them. In the case of grouping, it is preferable to first display the operation menu screen and select from the menu screen to switch the group.
In addition, a switch operation display screen may be provided, but it can also be used as a monitor for an existing navigation system that can share the input / output interface to the electrical equipment side, and a simple input / output port is added to the heater control switch, etc. In addition, it is possible to control each electrical component simply by adding an operation menu to the operation screen.

  A microcomputer is mounted inside the control box, and a printed circuit board provided with an input circuit and an output circuit connected to the microcomputer is accommodated, and the input circuit is connected to the composite soft switch operating means and a multiplex communication line. The output circuit is preferably connected to each electrical component via a signal line.

Specifically, for example, between the control box and each electrical component, the electrical component performs a signal line for detecting on / off of the switch, and each electrical component loads a voltage on the switch detection signal line, On / off is detected by detecting a voltage drop caused by closing the contact.
On the other hand, on the control box side, components that operate the contact part, such as transistors and relays, are incorporated, and a command is sent from the composite soft switch operating means to the microcomputer having the switch element in the control box. The on / off control of the switch can be performed by operating a signal to the component to be operated.

As described above, the control box and the electrical components are preferably connected to each electrical component via a signal line. With this configuration, there is an advantage that no design change or additional parts are required depending on whether or not each electrical component is compatible with multiple signals.
And since it is not necessary to change the wiring by the side of each electrical component with respect to a control box from the past, the cost required for the change by the electrical component side can be made unnecessary.
Note that a plurality of electrical components that can support multiplex communication and are disposed in close proximity may transmit a control signal from the control box via the multiplex signal line. With this configuration, the number of communication lines between the control box and the electrical component can be reduced.

Further, a power supply circuit for supplying driving power is provided in the control box.
The power supply to the power circuit of the control box may be supplied from a battery or power may be supplied from the composite soft switch operation unit. In this case, the power circuit unit can be reduced, and the control box can be reduced in size. Can be realized

  Of the electrical components operated by the composite soft switch operation unit, electrical components equipped with a mechanical switch that allows a passenger to switch the switching circuit are connected to the control box via an individual communication line. Connected.

That is, the control box is connected to both the composite software switch operating means for operating the switch by screen operation and the mechanical switch.
As a switch that can switch the switch circuit with any switch by using both a soft switch and a mechanical switch, for example, a trunk opener switch, a fader lid switch, a door mirror opening / closing switch, a power seat switch for adjusting a seat position, etc. Examples include hazard switches and power window switches.
On the other hand, preferable switches that switch the switch circuit only with the soft switch include a traction control off switch, an AFS switch, a transmission mode change switch, a meter illuminance adjustment switch, a suspension mode change switch, a TPMS switch, and a 100V switch. .

  For example, for electrical components mounted near the driver's seat or switches that require urgency, it may be easier for the passenger to operate the electrical components directly than on the display screen. is there. For example, the mechanical switch is easier to use to open and close the window on the side of the driver's seat. Such an electrical component mechanical switch is connected to the control box individually via a communication line, and if the electrical component is controlled by operating the mechanical switch, there is an advantage that the operation can be speeded up. On the other hand, it is preferable that an electrical component operated only by a soft switch is an electrical component that is relatively urgent and less frequently used.

  The electrical equipment that can be operated with the mechanical switch also serves as a soft switch that can be operated on the display screen. However, the mechanical switch is not limited to the soft switch but may be only the mechanical switch. A switch may be connected to the control box via a signal line and controlled by a microcomputer in the control box.

It is preferable that the composite soft switch operation unit includes a collective operation display unit capable of collectively performing a switch operation on a plurality of electrical components connected to the control box.
Specifically, when it is desired to stop the electrical components all at once when the vehicle is parked and alighted, the operation can be speeded up. For example, the operation of electrical components performed at the time of getting off, such as “close window”, “fold door mirror”, “turn off lights”, “stop wiper”, “stop air conditioner”, “turn off audio”, etc. It is preferable to provide a “get-off mode switch”. Similarly, it is preferable to provide a “ride mode switch” that collectively controls the electrical components that are performed when the user gets on the vehicle.

The mechanical switch is preferably a momentary switch.
This is because if the mechanical switch is a type of switch that is fixed by an on / off operation, a contradiction occurs between the two due to the on / off operation of the soft switch.
Further, the mechanical switch is preferably a momentary switch with an indicator that is lit during operation.

  The control box is mounted on the outer peripheral surface of an instrument panel / harness (hereinafter, the instrument panel is abbreviated as instrument panel) by tape winding or fastening with a fastening band, and connected to the control box via multiple communication lines. The composite soft switch operation section is preferably arranged on the outer surface of the instrument panel or the center console panel.

As described above, when the control box is mounted on the instrument panel harness by tape winding or the like, it is not necessary to fix the control box to the panel, and the degree of freedom of installation of the control box can be increased. In addition, since the number of wires is greatly reduced by connecting the control box and the composite soft switch operation unit with multiple communication lines, the number of wires inside the instrument panel where high-density wires and electrical components are arranged can be reduced. .
Furthermore, the composite soft switch operation unit is provided on the outer surface of the instrument panel or the center console panel so that the driver can easily operate. And, as described above, since the display device such as the monitor of the navigation system is mounted on the instrument panel and the center console panel, the display device can be used, and the number of dedicated parts can be reduced. The cost can be reduced accordingly.

  As described above, in the on-vehicle electrical component operation switch device of the present invention, the control device is provided between the composite software switch operating means having the switch operation unit displayed on the screen and the electrical component, and the control device is combined. Because it is connected to the soft switch operation section via multiple communication lines, the number of wires connected to the composite soft switch operation means having the switch operation section of a large number of electrical components can be rapidly reduced, reducing the burden during connection work, The occupied space, the number of parts and the weight can be greatly reduced.

  In addition, it is preferable to operate with mechanical switches rather than operating electrical components with soft switches operated on the screen. For electrical components that are preferable to operate with mechanical switches and electrical components that are easier to operate with mechanical switches, both soft switches and mechanical switches coexist. If the switch can be operated from any of the switches, the operation switch device can be very easy to use.
