DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control apparatus for an automobile engine which is used to remotely start at least an automobile engine from outside the automobile compartment.

[0002]

2. Description of the Related Art A remote control device for an automobile engine for remotely starting the engine of the automobile from outside the vehicle compartment has been conventionally known, for example, as described in Japanese Utility Model Application Laid-Open No. 2-42102. Used in practice.

When starting an automobile engine using a remote starter, a radio signal is transmitted by operating a portable first transceiver. This radio signal is received by a second transceiver provided in the automobile,
Sent to controller. And, in this controller, the second transceiver receives a radio signal from the first transceiver,
Only when safety and other conditions are satisfied, a start command signal is issued. On the basis of the start command signal, an ignition switch constituting the start device is closed, the starter motor is driven, and the engine is started.

As such a remote control device for an automobile engine, in recent years, a remote control device for an automobile engine has been proposed which starts an automobile engine from outside the vehicle compartment and allows the operating state of the engine to be easily checked from outside the vehicle compartment. , Actually used in some. Such a remote control device for an automobile engine includes a first transceiver that can be carried by an operator, a second transceiver provided in the automobile, a controller, a starting device, an operation detection device, A display unit provided in a part of the first transceiver so as to allow an operator to easily confirm an operation state of the engine.

[0005] In order to start the engine from outside the vehicle compartment, the operator operates the first transceiver so that a radio signal for starting the engine is transmitted by the first transceiver. When the second transceiver receives the wireless signal, the controller issues an engine start command signal.
The starting device starts the engine based on the start command signal. On the other hand, when the operator wants to check the operation state of the engine, he operates the first transceiver so that the first transceiver transmits a radio signal for checking the operation state of the engine. . The second transceiver that has received the wireless signal transmits a wireless signal based on a signal indicating the operating state of the engine detected by the operation detecting device. The first transceiver that has received the wireless signal allows the operator to easily check the operating state of the engine on the display unit.

[0006]

In the case of the above-mentioned conventional remote control device for an automobile engine, an operator operates the first transceiver to start the engine to transmit a radio signal. After that, in order to confirm the operating state of the engine, it is necessary to perform an operation different from the operation for starting the engine by pressing a switch provided on the first transceiver. That is, the radio signal transmitted by operating the first transceiver to start the engine by the operator, even when the second transceiver receives, for reasons such as failure of the starting device or engine, The engine may not work properly. In the case of a conventionally used remote control device for an automobile engine, when the controller issues an engine start command signal, a radio signal indicating that the engine start control has been started is transmitted to the first transceiver. It is transmitted, and it is possible to confirm that the engine start control is started by the first transceiver. However, simply confirming that the start control of the engine has been started in this way does not tell whether or not the engine actually operated normally. In order for the operator to confirm that the engine was working properly,
As described above, apart from the operation for starting the engine, it is necessary to perform an operation such as pressing a switch, which is troublesome. The vehicle engine remote control device of the present invention has been invented in view of the above-described circumstances.

[0007]

The vehicle engine remote control device of the present invention transmits at least a radio signal for instructing start of the engine, similarly to the above-described conventional vehicle engine remote control device. A first transceiver, a second transceiver that receives a wireless signal from the first transceiver, and a controller that issues a start command signal when the second transceiver receives a wireless signal, A starter for starting the engine based on the start command signal, an operation detector for detecting an operation state of the engine and inputting a signal representing the operation state to the controller, and a part of the first transceiver; And a display unit that allows the operator to easily check the operation state of the engine.

In particular, in the remote control device for an automobile engine according to the present invention, at least one after a predetermined time has passed since the controller issued the engine start command signal.
Times or more, the second transceiver transmits a radio signal based on the signal indicating the operation state of the engine detected by the operation detection device at that time, and the first transceiver that has received the radio signal, The operation state of the engine at the time described above can be easily checked by the operator.

More preferably, a light emitting diode or a liquid crystal display is used as a display unit provided in the first transceiver, and a part of the light emitting diode or the liquid crystal display is turned on, displayed, or blinked. The operator can easily confirm whether the engine is under start control or is operating.

Further, when a liquid crystal display is used as a display unit provided in the first transceiver, it is more preferable that a schematic diagram of the automobile can be freely displayed on the liquid crystal display, and that the schematic representation of the automobile can be displayed. A schematic diagram representing a device provided in an automobile can be freely displayed inside or in the vicinity of the drawing, and by displaying or extinguishing this schematic diagram, the operating state of the device can be easily checked by an operator.

[0011]

According to the remote control apparatus for an automobile engine of the present invention configured as described above, after the engine start command signal is issued, the operation state of the engine at that time is changed at least once or more. The display unit provided on one transceiver makes it possible for the operator to easily check. For this reason, the operator can easily confirm the operating state of the engine without performing any troublesome work only by performing the operation for starting the engine by the first transceiver.

Further, according to a preferred configuration, the first transceiver turns on, displays, or blinks a part of a light emitting diode or a liquid crystal display used as a display unit, so that the engine can be controlled during start control. Since it is possible for the operator to confirm whether the engine is present or in operation, the operator can instantaneously determine the operation state of the engine, and the visibility and operability of the operator can be improved.

Further, according to a more preferred configuration, a schematic diagram representing a device provided in the automobile can be freely displayed inside or near the schematic diagram of the automobile which can be freely displayed on the liquid crystal display, and this schematic diagram is displayed. Alternatively, the operating state of the device can be confirmed by the operator by eliminating the device. Therefore, by associating the arrangement position of the schematic diagram with the actual arrangement position of the device in the automobile, the operator instantaneously determines the meaning of the display state of the schematic diagram, and The operation status can be confirmed. Therefore, the visibility and operability of the operator can be further improved.

1 and 2 show a first example of an embodiment of the present invention corresponding to claim 1. FIG. 1 is a block diagram of a remote control device for an automobile engine according to the present invention. To
FIG. 2 shows the transmission and reception states of the first and second transceivers 2 and 3 and the display state of the display unit 7 provided in the first transceiver 2 when the engine 1 is remotely started. A remote control device for an automobile engine according to the present invention includes a first transmitter / receiver 2 provided on an operator side (A) for transmitting at least a radio signal for instructing start of the engine 1, and a vehicle side (B). , A second transceiver 3 for receiving a radio signal from the first transceiver 2, and a second transceiver 3
Controller 4 that issues a start command signal when a radio signal is received
A starting device 5 for starting the engine 1 based on the starting command signal, an operation detecting device 6 for detecting an operating state of the engine 1 and inputting a signal representing the operating state to the controller 4; A display unit 7 provided in a part of one transceiver 2 so that an operator can easily check the operation state of the engine 1
And When the remote control device of the automobile engine is started, the judgment conditions stored in the storage means such as the RAM incorporated in the controller 4 are transferred to the control circuit of the controller 4, so-called initial setting. Perform After performing the initial setting, when the second transceiver 3 receives a radio signal from the first transceiver 2 and conditions such as safety are satisfied, the engine 1 is remotely started.

That is, after the initial setting, the controller 4 always determines whether or not the second transceiver 3 is receiving a radio signal from the first transceiver 2, and determines whether the second transceiver 3 is wireless. If it is determined that a signal has been received, start and stop of the engine 1 and the like are controlled. That is, a radio signal for instructing that the engine 1 should be started is transmitted from the first transceiver 2 (A transmission), and the second transceiver 3 receives this radio signal (B reception). In this case, a start command signal (engine rotation flag) indicating that the engine 1 should be rotated is started (turned on). When the engine rotation flag is turned on, the starter of the engine 1 is started several seconds after the ignition switch constituting the starting device 5 is turned on, on condition that confirmation of safety or the like is performed by an interrupt routine. Start.

At this time, the controller 4 sets a predetermined time x (for example, 0) from the time when the second transceiver 3 receives a radio signal for starting the engine 1 (B reception).
After a lapse of about 1 second, a radio signal indicating that the start control of the engine 1 has been started is transmitted by the second transceiver 3 (B transmission 1). The first transceiver 2 that has received this radio signal (A reception 1) displays on the display unit 7 that the start control of the engine 1 has been started (display 1), so that the operator can confirm it.

In particular, in the case of the remote control device for an automobile engine according to the present invention, the controller 4 controls the second transceiver 3
A predetermined time y (for example, a short time of about 7 seconds) set in advance from the time when the wireless signal is transmitted (B transmission 1)
After the lapse of time, the operation detection device 6 detects at that time,
A radio signal based on a signal indicating the operation state of the engine 1 is
The transmission (B transmission 2) is performed by the second transceiver 3.
That is, when the engine 1 is operating normally at the above time and the operation detecting device 6 detects the operation of the engine 1, a signal indicating that the engine 1 is operating is input to the controller 4. I do. Conversely, when the engine 1 has not yet been operated and the operation detecting device 6 has detected that the engine 1 is not operating, a signal indicating that the engine 1 is under start control is input to the controller 4. I do. When the engine start control is stopped due to a detection error of a safety condition for starting the engine or the like, a signal indicating that the engine has been stopped and the cause of the stop are input to the controller 4. Then, the controller 4 causes the second transceiver 3 to transmit a wireless signal based on a signal indicating the operating state of the engine 1. The first transceiver 2 that has received the radio signal (A reception 2) displays the display 2 indicating the operating state of the engine 1 on the display unit 7 instead of the display 1 for a predetermined time z.
(For example, for 8 seconds) so that the operator can confirm it.

If the engine 1 does not operate normally (does not enter an idling state) even if the starter motor is driven for a predetermined time (several seconds) in order to operate the engine 1, the engine 1 is operated in order to operate the engine 1. The driving of the cell motor is repeatedly performed for a predetermined time (several seconds) by a controller different from the controller 4 up to a predetermined number of times (for example, three times).

According to the remote control apparatus for an automobile engine of the present invention configured as described above, the operating state of the engine 1 at the above-mentioned time point after the start command signal of the engine 1 is issued,
The display unit 7 provided in the first transceiver 2 makes it possible for the operator to easily check. Therefore, the operator can easily confirm the operating state of the engine 1 only by performing the operation for starting the engine 1 by the first transceiver 2.

Next, FIG. 3 shows a second embodiment of the present invention.
An example is shown. In the remote control device for an automobile engine according to the present embodiment, the controller 4 transmits a radio signal indicating the operation state of the engine 1 detected by the operation detection device 6 to the second transceiver 3.
(See FIG. 1) when the radio signal indicates that the engine 1 is not operating and the start control is being performed when the signal is transmitted (B transmission 2). That is, at a point in time after the predetermined time y has elapsed since the controller 4 transmitted the wireless signal (B transmission 1) by the second transceiver 3, the engine 1 is not operating yet, and The radio signal transmitted (B transmission 2) by the second transceiver 3 is
This may indicate that the engine 1 is under start control. In the case of this example, only when the radio signal transmitted by the second transceiver 3 indicates that the engine 1 is under start control, a predetermined time z from the time of transmission of the radio signal is used. After a lapse of (for example, 8 seconds), the second transceiver 3 transmits a wireless signal based on the signal indicating the operation state of the engine 1 detected by the operation detection device 6 at that time (B transmission 3). Then, the first transceiver 2 that has received the wireless signal (A reception 3) displays the display 3 for several seconds instead of the display 2 on the display unit 7 provided in the first transceiver 2, The operating state of the engine 1 can be easily confirmed by the operator.

In the case of the present embodiment configured as described above, only the operation for starting the engine 1 is performed, and the operating state of the engine 1 after the start operation of the engine 1 is more improved than in each of the above-described examples. Confirmation can be made freely for a long time.
Other configurations and operations are the same as those in the above-described first example, and thus redundant description will be omitted.

Next, FIGS. 5 to 11 show a second embodiment of the present invention described above, as an example of the case where the second embodiment of the present invention is specifically implemented. Three examples are shown by a flowchart on the first transceiver 2a side as shown in FIG. In the case of this example, as shown in FIG. 4, the first transceiver 2a uses a light emitting diode (LED) 8, 8 as the display unit 7, as shown in FIG. The light emitting diode 8 in the RUN / SET portion, which is a part of the light emitting diodes 8, 8 is turned on and blinked, so that the engine is under start control (SET) or is operating (RUN). It is made possible for the operator to confirm whether or not. The configuration and operation when the engine is remotely started using such a first transceiver will be described in detail below. FIG. 5 shows the engine 1 (FIG. 1).
FIGS. 6 to 10 are flowcharts showing the operation of the first transceiver 2a when remote control is remotely started.
Are partially shown, and a display state of the display unit 7 and the like are respectively shown. The symbols (a1, a2, etc.) in the frame of the flowchart show the display state of the display unit 7 and the like, respectively. Also, in the case of the present example, as described later, when a signal for starting the engine 1 is sent from the first transceiver 2a even though the engine 1 has already been started, a3, As a4, the operating state of the engine 1 is displayed.

First, the engine 1 is connected to the first transceiver 2.
In order to remotely start the system by a, as shown in FIG. 6, a START / STOP switch 9 (FIG. 4) provided on the first transceiver 2a is continuously pressed twice (performs two actions).
Then, the first transceiver 2a transmits a radio signal for instructing that the engine 1 should be started (A transmission). Accordingly, the light emitting diode 8 in the SEND portion provided on the display unit 7 is blinked for several seconds (for example, 3 seconds), then turned on, and the buzzer is turned on (sounds) twice. And
Only when the second transceiver 3 receives the radio signal (B reception) and when conditions such as safety are satisfied,
The controller 4 issues a start command signal for the engine 1, drives the starter motor constituting the starting device 5 (FIG. 1) based on the start command signal, and starts the engine 1. or,
The controller 4 controls the engine after a predetermined time x (for example, 0 to 1 second) that has been set in advance from the time when the second transceiver 3 receives a radio signal for starting the engine 1 (B reception). A radio signal indicating that the start control of No. 1 has been started is transmitted (B transmission 1) by the second transceiver 3. Then, as shown in FIG. 7, the first transceiver 2a that has received this wireless signal (A reception 1) turns on the light emitting diode 8 of the RUN / SET portion provided on the display unit 7 for several seconds (for example, 10 seconds). ) In addition to flashing and displaying (display 1), the buzzer is turned on twice so that the operator can easily confirm that the start control of the engine 1 has been started.

After a lapse of a predetermined time y (for example, 7 seconds) from the time when the controller 4 causes the second transceiver 3 to transmit the radio signal (B transmission 1), the operation detecting device is activated at that time. 6 (FIG. 1) transmits a wireless signal based on the signal indicating the operating state of the engine 1 detected by the second transceiver 3 (B transmission 2). For example, at this time, the engine 1 is operating normally and the operation detecting device 6
Detects the operation of the engine 1, the first transceiver 2 a receives the radio signal (B reception 2), and as a1-1, the light emitting diode of the RUN / SET portion provided on the display unit 7 8 is turned on for several seconds (for example, 10 seconds) and displayed (Display 2), and the buzzer is turned on twice so that the operator can easily confirm that the engine 1 is operating.

On the other hand, if the engine 4 is not operating for some reason even though the controller 4 has issued a start command signal to the starting device 5 to start the engine 1 at the time, the operation detection is performed. The first transceiver 2a receives a radio signal based on a signal indicating that the engine 1 is under start control detected by the device 6, and as shown in FIG. RUN / S provided in 7
The light emitting diode 8 in the ET portion is blinked for several seconds (for example, 10 seconds) for display (display 2), and the buzzer is turned on for 2 seconds.
Turns ON to confirm that the engine 1 is under start control.

As described above, the operation detecting device 6
In order to detect whether the engine 1 is operating or under start control (non-operating state), the operation detecting device 6 is connected to the L terminal of the alternator to measure a voltage value,
Alternatively, it is conceivable to take measures such as measuring the number of revolutions of the tachometer.

In addition, when the engine 1 is not operating at the above time, a radio signal based on a signal indicating that the engine 1 is under start control detected by the operation detecting device 6 is transmitted to the second transceiver. 3, when the predetermined time z (for example, 8 seconds) has elapsed since the transmission of the wireless signal, the engine detected by the operation detection device 6 at that time, as described in the second example described above. A radio signal based on the signal indicating the operating state of No. 1 is transmitted by the second transceiver 3 (B transmission 3). Then, the first transceiver 2 that has received the wireless signal (A reception 3) displays the display 3 for a few seconds on the display unit 7 provided in the first transceiver 2 to change the operating state of the engine 1. It can be easily confirmed by the operator. In this case, the display state of the first transceiver 2 indicating the operation state (during operation or start control) of the engine 1 is shown in FIG.
In FIG. 10, a1-1-1 and a1-1-3 are shown, respectively.
Since it is as described as the display state of 1-3 and the like, the overlapping description is omitted.

When the second transceiver 3 transmits a radio signal (B transmission 1, B transmission 2, B transmission 3),
When the safety condition for starting the engine 1 is not satisfied and the engine 1 cannot be started, the controller 4 does not output a command signal for starting the engine 1 and instead, A wireless signal indicating that the safety condition is not satisfied is transmitted. For example, as a safety condition for starting the engine 1, in the case of an automatic vehicle, there are conditions such as that a shift lever is at a predetermined position, a stopping brake is securely operated, and a door of the vehicle is closed. If all of these conditions are not satisfied, a radio signal indicating that the safety conditions are not satisfied is transmitted as described above. At this time, the first transceiver 2a that has received the radio signal, as shown in FIG.
As 2, a1-2 and a1-1-2, the light emitting diode 8 in the STOP / RESET portion provided on the display unit 7 is lit for a few seconds (for example, 10 seconds) and displayed, and the buzzer is turned on three times. It is possible to confirm that the safety conditions are not satisfied.

FIGS. 6 and 7 show a case where a reception error occurs when the first transceiver 2a receives a radio signal (A reception 1, A reception 2, A reception 3). Like (A
In the case of 3 o'clock reception, the illustration is omitted), the light emitting diodes 8 of the RUN / SET portion and the STOP / RESET portion provided on the display unit 7 are respectively turned on for a few seconds (for example, 10 seconds), and the buzzer is displayed. It is turned ON three times to make it possible to confirm that the reception error has occurred.

Further, when starting control of the engine 1 is started and the second transmitter / receiver 3 transmits a radio signal (B transmission 1), if the vehicle burglar alarm device is operating, an alarm is issued. The second transceiver 3 transmits a wireless signal indicating that the switch has been turned on. Then, the first transceiver 2a that has received this radio signal is referred to as the first transceiver 2a as e1.
By flashing all the light-emitting diodes 8 provided in the printer and continuously turning on the buzzer, it is possible to confirm that the alarm has been turned on. In this case, control for starting the engine 1 on the vehicle side is not performed.

According to the remote control device for an automobile engine of the present embodiment configured as described above, the light emitting diode 8 on the RUN / SET portion of the display unit 7 provided in the first transceiver 2a is turned on or off. The operator can easily confirm whether the engine is under start control or operating. That is, the light emitting diode 8 in the RUN / SET portion is turned on to make it possible to confirm that the engine 1 is operating, and to make it possible to confirm that the engine 1 is under start control, The light emitting diode 8 in the SET portion blinks. Therefore, the operator does not need to determine which part of the light emitting diode 8 is lit to confirm the operating state of the engine, and the visibility and operability of the operator are improved. Further, in order to allow the operating state of the engine 1 to be easily checked, it is not necessary to increase the number of the light emitting diodes 8, and the cost of the entire remote control device for the vehicle engine can be reduced. With the vehicle engine remote control device of the present embodiment, the operator only performs an operation for starting the engine 1 with the first transceiver 2,
The operation itself, which allows the operating state of the engine 1 to be easily checked without any troublesome work, is the same as in the case of the above-described second example.

In the case of this example, when a radio signal for instructing that the engine 1 should be started is sent to the first transceiver 2a even though the engine 1 has already been started. A signal indicating whether the engine 1 is operating or the engine 1 is under start-up control is sent to the engine, and the display state of the first transceiver 2a or the like (a3, a4) The operating state of No. 1 can be checked freely.

Further, as described above, by limiting the time when the light emitting diode 8 is turned on or off to a predetermined time (several seconds), energy saving in the first transceiver 2a can be reduced. As a result, the consumption of the battery can be prevented. Further, as described above, the radio signal transmitted by the second transceiver 3 is transmitted intermittently at predetermined time intervals (x, y, z), and the first transceiver 2a transmits the radio signal. The display state of the display unit 7 is intermittently changed based on the signal. Therefore,
In the case of the present example, the first transceiver 2a does not need to continuously change the display state of the display unit 7 with continuous reception, and energy can be saved in the first transceiver 2a.

Next, a case where the engine 1 is remotely stopped from outside the vehicle compartment while the engine 1 is operating will be described. In order to stop the engine 1 remotely, as shown in FIG. 11, when the START / STOP switch of the first transceiver 2a is pressed once, the first transceiver 2a informs that the engine 1 should be stopped. Transmits a radio signal for instruction. Along with this, the light emitting diode 8 in the SEND portion provided on the display unit 7 is turned on to display, and the buzzer is turned on twice.

When the second transceiver 3 receives a radio signal for instructing that the engine 1 should be stopped, the controller 4 issues a stop command signal and immediately stops the engine 1. Then, the second transceiver 3 transmits a radio signal indicating that the stop control of the engine 1 has been performed.
When the first transceiver 2a receives this radio signal,
As shown in FIG. 11, the first transceiver 2a turns on the light emitting diode 8 of the STOP / RESET portion provided on the display unit 7 for a few seconds (for example, 10 seconds) to display the buzzer twice. It turns on, and it is possible to confirm that the stop control of the engine 1 has been performed. When the engine 1 is stopped, unlike when the engine 1 is started,
It is only necessary to turn off the main switch, and the engine 1 is immediately stopped.

FIGS. 12 to 17 show another embodiment of the second embodiment of the present invention, which corresponds to claims 2 and 3 of the present invention. 14 shows a fourth example of the embodiment. In the case of this example, as shown in FIG. 12, a liquid crystal display (L) is used as the display unit 7 as the first transceiver 2b used in the remote control device for the automobile engine.

It can be displayed and disappeared even for 8. Similarly, the display portions "P, B, D, H, R" which can be freely displayed at the lowermost portion allow the operator to easily confirm the inoperable factor when the engine 1 does not operate. That is, the lighting of "P" indicates that the shift lever is not at a predetermined position (parking position) in the automatic car, the lighting of "B" indicates that the stopping brake is not operated, and the lighting of "D" indicates Confirm that the door is open, turn on the "H" to indicate that the hood is open, and turn on the "R" to confirm that the initial registration for starting the engine is inappropriate (NG). It is free.

In particular, in the case of the remote control device for an automobile engine according to the present embodiment, the part of the liquid crystal display 10 provided in the first transceiver 2b, that is, the part of the schematic diagram 17 of the cooling fan is displayed or disappears. By doing so, it is possible to confirm to the operator whether the engine 1 is under start control or operating. Hereinafter, the first transceiver 2 used in this example

Disappears, it is possible to confirm that the theft alarm device has been released.

Next, the vehicle interior temperature, the operating state of the engine,
In the case where a radio signal is transmitted by the first transceiver 2b in order to simultaneously inspect the locked state of the door and the set state of the theft alarm device, that is, to indicate that a so-called all check should be performed, the second transceiver is used. The display state and the like of the liquid crystal display 10 when the confirmation radio signal from 3 is received by the first transceiver 2b will be described. In such a case, when the switch 9 of the CHECK portion provided in the first transceiver 2b is pressed, the first transceiver 2b instructs that all states of various devices of the automobile should be checked. Transmits a wireless signal. The second transceiver 3 having received the wireless signal transmits a wireless signal based on a signal obtained by inspecting the state of the various devices.

The first transceiver 2b, which has received the radio signal, can simultaneously confirm the vehicle interior temperature, the operating state of the engine, the locked state of the door, and the set state of the theft alarm device by the liquid crystal display 10. I do. For example, FIG. 17 shows a display state of the first transceiver 2b in a state where the engine is operating, the door is locked, and the burglar alarm device is set. Like this
In the case of this example, the operator can confirm the states of various devices of the automobile by performing only one switch operation in order to perform the all check. On the other hand, in the case of a conventional remote control device for an automobile engine, various states of the automobile can be individually displayed by one switch operation. In the case of this example, as described above, it is possible to simultaneously confirm the states of various devices of the vehicle with a single operation, thereby improving the visibility and operability of the operator. However, as in the conventional structure, it is of course possible to make it possible to individually confirm various states of the automobile by operating the switch once.

In the case of the present embodiment, the schematic diagram 18 of the automobile can be freely displayed on the liquid crystal display 10 as described above, and the engine, the cooling fan, the key, Schematic diagrams with siren 14, 15, 16, 1
7 are freely displayed, and these schematic diagrams 14 to
By displaying or extinguishing 17, the operating state of the engine 1, the locked state of the car door, and the set state of the burglar alarm device can be checked freely. Therefore, in the case of this example, the operability and visibility of the operator can be further improved. That is, in the case of a conventionally used remote control device for an automobile engine, as shown in an example of a liquid crystal display device in FIG. And the set state of the burglar alarm device, respectively, are arranged in a random manner without any relation to each other. For this reason, in the case of the conventional structure, it is difficult for the operator to instantly judge the meaning represented by each of the schematic diagrams, and it is difficult to confirm the states of the various devices, and the visibility of the operator is poor. Such poor visibility of the operator is not preferable because it causes a decrease in operability. In the case of this example, as described above, inside or in the vicinity of the schematic diagram 18 of the automobile that can be freely displayed on the liquid crystal display 10, each schematic diagram representing various devices that can be displayed or erased is arranged. ing. And since the arrangement | positioning position of the schematic device showing various apparatuses in the schematic diagram 18 of the said vehicle is ideally linked with the arrangement position of the said apparatus in an actual vehicle, an operator instantly represents the various apparatuses. By judging the meaning, the operating states of these various devices can be confirmed. Therefore, the visibility and operability of the operator can be further improved.
