Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a remote control device that has an operating section on a steering wheel. Specifically, when the driver of a car handles the steering operation, he or she touches the n-joint to apply rotational force to the steering wheel, which has a circular or circular shape, and has an operation part installed on the steering wheel, and a receiver and load placed on the car body. The present invention relates to a remote control device in which remote control operations can be performed from the operating section.

Conventionally, only a horn switch was provided on the steering wheel.

This means that a sliding contact or = 1-il-shaped cord must be provided for signal transmission between the rotating part of the steering wheel and the vehicle body where the load is installed, and that there is no device on the steering wheel that can be removed by humans. Because of the inability to operate the horn, the system is configured such that only the minimum essential horn operation is possible when operating the steering wheel.

However, in general, as automatic vehicles become more and more sophisticated, electrical operations have become more diverse. Therefore, it is desirable to be able to control the electrical system easily and safely even when the vehicle is running or when operating the steering wheel. For this purpose, it is most desirable to provide various operating units on the steering wheel closest to the driver.

However, in order to install various operating sections on the steering wheel, due to mounting issues, the operating section must have an extremely simple structure, and the receiving section, which is a stationary section opposite to the rotating section of the steering wheel section, must be installed. The wiring that connects them is complicated and in some cases requires the use of many sliding contacts, leading to problems such as undesirable reliability. Therefore, it is desirable that the number of signal lines connecting the operating section and the remote receiving section be as small as possible. The present invention has been made from this viewpoint.

That is, an object of the present invention is to provide a steering wheel section with various operation switches so that even when the steering wheel is operated, remote control is possible, the operation section is simple in structure, and the number of types of operation signals is small. In comparison, it is an object of the present invention to provide a remote control device that can be operated remotely using a plurality of signal lines with a small number of signal lines.

The present invention comprises an operating section provided on an automobile steering wheel, a receiving section provided on the vehicle body side, and a plurality of signal lines connecting the front 8d operating section and the receiving section, The operating section converts the voltages applied to the plurality of signal lines from the input switch section for remote operation and the receiving section into binary parallel codes in accordance with the operating state of the input switch section. and an encoder section that converts the encoded signal into a decoding signal, and the receiving section decodes the binary parallel omitted signal that appears on the plurality of signal lines and is converted by the encoder section, and generates a corresponding decoded signal. The decoder section is characterized by having a decoder section that outputs an output, and a power supply section that supplies power to a specific load specified by the binary parallel encoded signal in accordance with the decoded signal outputted from the decoder section. A remote control consists of one control device.

FIG. 1 is a block diagram representing the concept of the present invention. The operating unit 1.0 has a compact structure so as to be installed on a steering wheel. Here, the steering wheel is made of circular parts that are rotated by the driver of the car by applying the -E joint for steering operations.The steering wheel is located in the center. It consists of a boss part, a surrounding ring part, and a wheel part that connects these parts.

The operating portion may be provided anywhere on the rotating portion of the steering wheel.

The operation section 10 is composed of an input switch section 2o and an encoder section 30. For example, a pushbutton switch, snap switch, 1-glue switch, etc. can be used.

The encoder section 30 is a section that generates parallel encoded signals that are binarized according to the operation status of the switch section. The plurality of signals $5i+40 are supplied with voltage from the on-vehicle battery via the receiver 50 installed on the vehicle body. and is encoded according to the operation status of the input switch.

Multiple 40G signal lines are installed in the steering wheel section.
The operating section 10 installed on the vehicle body and the receiving section 1 installed on the vehicle body 5
Generally, a sliding contact is used in the middle.

The receiver 1R section 50 mainly consists of a decoder section 60 and a feeder 7u section 70. The decoder section 60 has a function of decoding the binary parallel encoded signals appearing on the plurality of signal lines 40, decoding them according to the binary parallel encoded signals, and generating a decoded signal of 1=result. Here, the decoding signal is a signal indicating which switch on the back of the input switch section 20 has been operated. The power supply section 70 has a switching power supply function that receives the decoded signal from the decoder section 60 and starts supplying power only to the load specified by the binary encoded signal.

The present invention consists of the above configuration. The effect of the rest is as follows. By operating the input switch section 20, the signal is encoded by the encoder section 30 and reaches the decoder section 60 via a plurality of signal lines 40. The decoder section 60 decodes the binary encoded signal, and the power supply section 70 supplies power to the load specified thereby.

As described above, the present invention provides an operation section in the steering wheel section to remotely control a plurality of loads installed on the vehicle body, and uses a binary coded signal as the signal format. The points are distinctive. If the number of signal lines is +1, it is possible to send out 2fL-1 types of operation signals. Therefore, it is possible to transmit more types of signals than the number of signal lines.

Hereinafter, the present invention will be explained in more detail with reference to specific examples. Fig. 2 t, remote control of the present invention [1-
FIG. 1 is an electrical circuit diagram showing a specific embodiment of the device. The blocks surrounded by one-dot chain lines correspond to the block [1] in FIG. 1, and the corresponding blocks are given the same numbers as in FIG. 1. The input switch section 20 is composed of seven push button switches 21-27. Each pushbutton switch is connected in parallel and is connected to a plurality of signal lines/IO via a data 1-data section 30, respectively.

The decoder section 30 is connected to 33 lines (ftj f:, l) 1-- so that it outputs a specific binary encoded signal when a specific pushbutton switch is pressed.
Diodes up to D9 and three signal lines 41 to /I each
This is a diode for preventing the signal voltage from being diverted in order to hold each of the three independently.

Each signal line 7IO is connected to the vehicle battery 75 via resistors R1, R2, and R3, respectively.

Therefore, when all the push button switches of the input switch section 20 are in the open state, all three signal lines are in the high level state. When one of the push button switches is pressed, the signal line connected by the decoder section 30 is grounded via the switch, and only the signal line at the bottom becomes low level, converting the signal line voltage into a binary parallel code. It will become

This encoded voltage is sent to a receiving section 5 provided on the vehicle body side.
It is decoded by the decoder section 60 which constitutes a part of 0. Among the three signal lines, some signal lines are inputted to the AND circuits 61 to 67 via an inverter, and the other signal lines are directly inputted to the AND circuits 61 to 67. 68N l) The circuit outputs a high level signal when all three inputs of each binary parallel encoded signal are at level H. The output of each AND circuit is 1-transistor Tr 1 to Tr 7 (Tr 4 to
1-r 7 is connected to the base of (not shown).

Relays 71 to 77 (74 to 77 are not shown) are connected to the collectors of the 1-transistors Tr1 to ``rr7, and these relays are connected to the positive electrode of the vehicle battery 75. Relay contacts 71a to 77a (74a to 77a are not shown) that operate by transmitting power from the vehicle battery 75 to loads 81 to 8, respectively.

The detailed operation of the above configuration will be explained next.

- ■ - The I- data section 30 generates a binary parallel code of negative logic depending on whether any of the switches 21 to 27 is in the on state. & conversion]-encoder. When only the switch 21 is turned on, only the signal line 41 is at a low level, and 42.43 is at a high level. Therefore, the signal lines 41, 42, 4.3 are connected in this order to 2 to the 0th power and 2 to the 1st power.
If we use the signal line to represent the digit of the power of 2 and the square of 2, this is 00
A binary parallel code signal of 1 (negative logic, the same applies hereinafter) is shown.

Also, if only the push button switch 22 is operated, the
Only FA 42 is low level and is encoded as 010. Similarly, when only switch 23 is closed, only signal lines 41 and 42 are at a low level, which is encoded as 011. Similarly, when the switch 24 is pressed, the code is 100, when the switch 25 is pressed, it is encoded as 101, when the switch 26 is pressed, it is encoded as 110, and when the switch 27 is pressed, it is encoded as 111.

Next, a decoder section 6 decodes this encoded voltage signal.
0 will be explained. A N I) The circuit 61 is the signal line 4
A signal of only 1 is input via an inverter 601. When the switch 21 is pressed, only the signal line 41 becomes low level. Therefore, all the signals input to the AND circuit 61 are high level signals.
Only the output of is at high level. Therefore, AN+) circuit 6
1, it is determined that the switch 21 has been operated. The high level signal of the AND circuit 61 is connected to the transistor I'
When r1 is turned on, current flows through the relay 71 connected to the collector, and the relay contact 71a is turned on to supply power to the load 81. Similarly, if only the switch 22 is pressed, only the signal line 42 will be at low level and 1. >, the output of only the AND circuit 62 to which the signal on the signal line 42 is input via an inverter becomes high level. Therefore, in this case, only the load 82 operates in the same manner as described above.

Thereafter, when only the switch 23 is closed in the same manner, the output of only the AND circuit 63 becomes high level, and the load 83
Power is supplied only to

A similar M reading will be performed up to switch 27.
, and when the switches at all are in the A-off position, a coded signal of 000 is input, the output of the AND circuit at the other end goes to a low level, and the power supply to all loads is cut off. In this way, it becomes possible to transmit the control signals 8 for seven loads through three signal lines.

Next, a remote control device according to another embodiment will be explained. Remote computer 1 according to other embodiments
The first to roll devices are the devices of the first embodiment except that a control signal storage circuit is installed. The first sea urchin, not shown in Figure 3,
In step r8 of the embodiment, for example, the A N l) circuit 61
The output of the 1-I type flip-flop L1/circuit 651, which is a binary binary state voltage holding circuit, is connected to the 1-1 terminal of the flip-flop L1/circuit 651, and the Q terminal output of the flip-flop II flip circuit 651 is connected to the

The output of the D circuit 62''-67 is similarly connected to the bases of 1-r2 to 1°r7 via flip-flop circuits 652 to 657.

The action will be explained below. First, when the car's ignition switch is turned on, a reset signal is sent to each flip-flop circuit to reset it. Next switch 21
When only 001 is pressed, the phrase 001 is converted to J (number 8 is propagated and decoded as J to the AND circuit 61, and its high level signal is input to the T terminal of the flip-flop circuit 651,
Holds the flip flop [177 circuit in the set state. Even if the switch 21 is opened to the A-blink state after being set, the fact that the switch 21 has been operated once is stored in the flip-flop circuit 651, and the power supply to the load 81 continues. Next, when the switch 21 is operated to suppress [1] for the second time and the same 001 encoded Shintan is transmitted, it is decoded only by the same AND circuit 61, and the △1 to D circuits 6
1 overrides the output of the Hatake level signal. Then, this second pulse is received by the Noritsubu 7 [1tsubu circuit 651] and the circuit goes into a reset state. Therefore, turn on the transistor ]−r1
The power supply to the load 81 is cut off. In this way, when one switch is connected to J3, the first operation is performed between the power supply to the load and f3 (
By using the second operation as a load power supply stop signal, it is possible to open the signal line 40 to other operation signals while power is being supplied to a specific load. Therefore, it is possible to operate multiple IIA+ operation switches in a time-sharing manner, and it is possible to start feeding power to multiple loads at the same 11N, making it a more effective remote controller than that of the first embodiment. The control can be operated 3. At this point, the input part 20 presses two switches at the same time.
If it is not possible, it is necessary to use a mechanical M4 configuration.

This is because if two switches are pressed at the same time, a code other than the one promised may be encoded, resulting in malfunction. Further, it is possible to configure an electric circuit such that the switches are prioritized.

In this embodiment, it has been explained that 7 operation signals are transmitted using 8 wires of 3 trees, but the present invention is not limited to the number of these signal lines and the number of operation signals. isn't it.

In short, the present invention provides a remote control device in which an operating section is provided on the steering wheel section, and a receiving section and a load are provided on the vehicle body side. Special A: A simple passive circuit that does not require a power supply line.
C17, S is constructed and the C-L-N-D is set to the right. A parallel encoded signal converted from 1 to 2 is used for signal transmission and reception, and the f'l bow conversion (ji '1) is decoded by +13 in the receiving section, and power supply to a specific load is started or This is for remote control of the stop.

Therefore, according to the crazy head of the present invention, it is possible to extremely easily install the operating section in the steering wheel section, which has little room for installation, and to control the number of signal lines connecting the rotating section and the non-rotating section. Since the number of signals can be reduced to a very small number compared to the number of signals, it is very effective for such a remote roll device having an operating section on the steering wheel. In addition, the operating section is made up of a passive circuit and does not require any special power supply.
