[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an engine starter remote control device for transmitting an engine start signal or an engine stop signal to an engine starter of a vehicle by an air propagation signal.

[0002]

2. Description of the Related Art Some of the conventional remote control devices for engine starters are provided with a start switch, a stop switch, and a mode switch on a main body case. The mode switch is provided to prevent erroneous operation, and the microcomputer inside the remote control device measures the fixed time after the mode switch is turned on once and then presses the start switch or stop switch within the fixed time. In that case, the switch operation is made effective, and a start signal or a stop signal is transmitted to the engine starter of a vehicle, for example, an automobile by microwaves or the like.

[0003]

However, such a remote control device has a problem that since it is necessary to provide three switches, the cost is high and the main body case is large and portability is poor. The present invention solves the above problems, and an object of the present invention is to provide a small-sized remote control device for an engine starter capable of controlling the start and stop of the engine with a function for preventing erroneous operation.

[0004]

In order to achieve the above object, a remote control device for an engine starter according to claim 1 transmits an engine start signal or an engine stop signal to an engine starter by an air propagation signal. When the start switch is turned on after the start switch, the stop switch, and either one of the start switch and the stop switch is turned on once or more as the start switch, a start signal is transmitted and the stop switch is turned on. And a control means for transmitting a stop signal when operated. In this case, the start switch is preferably a stop switch (claim 2).

According to another aspect of the present invention, there is provided an engine starter remote control device for transmitting an engine start signal or an engine stop signal to an engine starter of a vehicle by an air propagation signal. When the switch is turned on, a stop signal is sent,
After the stop switch or the start switch is turned on once or more, the control means transmits a start signal when the start switch is turned on.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A first embodiment of the present invention will be described below with reference to FIGS. FIG. 3 is a plan view showing the external appearance of the remote control device 1 for the engine starter.
On the surface of the main body case 2, two push button switches, that is, a start switch 3 which is a start switch, a stop switch, and a stop switch 4, which is a start switch, are vertically arranged. Further, above these switches, a transmission LED 5 that lights up and indicates that a signal is being transmitted is arranged. A transmission antenna 6 is provided on the upper part of the main body case 1.

In FIG. 4 showing the electrical structure, one terminal of each of the switches 3 and 4 is commonly connected to the positive electrode terminal of the battery 7, and the other terminal thereof is connected to the resistors 8a and 8 respectively.
It is connected to the ground via b. Also, switch 3
The common connection point between the resistor 8a and the resistor 8a and the common connection point between the switch 4 and the resistor 8b are connected to an input terminal of a microcomputer (hereinafter, referred to as a microcomputer) 9 serving as a control unit.

The ON signal output from the stop switch 4 also serves as a trigger signal for supplying power to the microcomputer 9. When the stop switch 4 is turned on, the power supply circuit inside the microcomputer 9 turns on. Upon receiving the rising edge of the ON signal, the power supply to the control unit (not shown) inside the microcomputer 9 is started. The output terminal of the microcomputer 9 is connected to the transmission antenna 6 via the transmission circuit 10 and transmits a start or stop signal to the engine starter (not shown), which is an air propagation signal, for example, by a microwave. .

Next, the operation of this embodiment will be described.
In FIG. 1 showing a flow chart of the control contents of the microcomputer 9, when the stop switch 4 is turned on and the power supply to the control unit is started, the microcomputer 9 first proceeds to a determination step S1 of “stop switch off?”. And waits for the stop switch 4 to be turned off. If the stop switch 4 is turned off and it is determined to be "YES",
The process moves to the process step S2 of "start time measurement".

In processing step S2, the microcomputer 9
Starts counting from the time when the stop switch 4 is turned off in step S1 by an internal timer (not shown). After this, the microcomputer 9 goes through the following "start switch on?" Judgment step S3 and "stop switch on?" Judgment step S4, and then "2 seconds elapsed?"
During the period from the start of the time counting operation to the lapse of 2 seconds while repeating steps S3 to S5 up to the determination step S5, the start switch 3 or the stop switch 4
Will wait until any of the above is turned on.

When the start switch 3 is turned on in the above-mentioned period, the microcomputer 9 judges "YES" in the judgment step S3 and shifts to the "start signal transmission" processing step S7. The starting signal is output as a microwave signal from the transmitting antenna 6 via the transmitting circuit 10. If the stop switch 4 is turned on during the above period, the microcomputer 9
Determines "YES" in determination step S4 and proceeds to processing step S8 of "stop signal transmission" to output the stop signal from the transmission antenna 6 via the transmission circuit 10 as a microwave signal.

When the start signal or the stop signal is transmitted as described above, the microcomputer 9 shifts to the processing step S6 of "power off" and controls the power supply circuit to turn off the power supplied to the control unit. When a signal is given, the process ends. Further, even if the above-mentioned period elapses, any switch 3,
If 4 is not turned on, the microcomputer 9 determines “YES” in step S5 and ends the process through step S6 without transmitting a signal.

Therefore, the operation of the microcomputer 9 is as shown in FIG.
As shown in the timing chart of Figure 3, the start switch 3 is activated within 2 seconds after the stop switch 4 is turned off.
Alternatively, if the stop switch 4 is turned on, the switch operation is valid (see), and if the stop switch 4 is turned on after 2 seconds, it is invalid (see). Also, it is invalid even when the stop switch 4 and the start switch 3 are simultaneously turned on (see).

As described above, according to this embodiment, the microcomputer 9 turns on the start switch 3 or the stop switch 4 within 2 seconds after the stop switch 4 is turned on and then turned off. Since the engine start signal or stop signal for the engine starter is transmitted, unlike the conventional case, it is only necessary to provide two switches 3 and 4 corresponding to start and stop without separately providing a start switch for preventing erroneous operation. The remote operation device 1 can be configured to have a small size and a low price because it can be configured to have an erroneous operation prevention function.

Further, according to this embodiment, since the stop switch 4 is used as the starting switch, even if an erroneous operation occurs in which the stop switch 4 is turned on twice without the user being aware, Remote control device 1
Since the stop signal is transmitted from, it is possible to prevent an erroneous start of the engine.

FIG. 5 shows a second embodiment of the present invention. The configuration of the second embodiment is similar to that of the first embodiment,
Only the operation different from that of the first embodiment will be described below. FIG. 5 shows a flow chart of the control contents of the microcomputer 9. Before the step S1 in the flow chart shown in FIG. 1 of the first embodiment, a "stop signal transmission" processing step S0 is inserted. .

Similar to the first embodiment, the microcomputer 9 starts the control according to the flowchart of FIG. 5 when the stop switch 4 is turned on and the power supply to the control unit is started, and immediately after that, the processing step S0 is started. In, the stop signal is transmitted from the transmission antenna 6. And
In the second embodiment, step S4 in the first embodiment is executed.
And S8 are deleted, and if the microcomputer 9 determines "NO" in step S3, the process proceeds to step S5. Therefore, when the microcomputer 9 validates the ON operation of the start switch 3, it is the same as in the first embodiment.

As described above, according to the second embodiment, the microcomputer 9 sends a stop signal to the engine starter when the stop switch 4 is turned on, and is turned off after the stop switch 4 is turned on. When the start switch 3 is turned on within 2 seconds after the start, the start signal is transmitted to the engine starter, so that the operation for transmitting the stop signal can be simplified.

FIG. 6 shows a third embodiment of the present invention. The configuration of the third embodiment is similar to that of the first and second embodiments, and only the operation different from that of the second embodiment will be described below. In the third embodiment, when one of the start switch 3 and the stop switch 4 is turned on, the power supply circuit inside the microcomputer 9 causes the control section of the microcomputer 9 to use the rising edge of the ON signal as a trigger signal. It is designed to supply power.

FIG. 6 shows a flow chart of the control contents of the microcomputer 9, and before the step S0 in the flow chart of the second embodiment shown in FIG. 5, a judgment step S8 of "stop switch on?" Is inserted. ing. When power is supplied to the control unit and the processing is started, the microcomputer 9 determines whether or not the switch turned on is the stop switch 4 in determination step S8. If the stop switch 4 is turned on and the microcomputer 9 determines “YES” in the determination step S8, the process proceeds to step S0, the stop signal is transmitted to the engine starter, and then the process proceeds to step S6 to stop the power supply. Ends the process.

If the stop switch 4 has not been turned on in the judgment step S8 and the microcomputer 9 judges "NO", the process proceeds to a judgment step S9 of "start switch off?". If the stop switch 4 is not turned on in the determination step S8, it means that the start switch 3 is turned on and power supply to the control unit of the microcomputer 9 is started. Therefore, in the determination step S9, the microcomputer 9 waits for the start switch 3 to be turned off, and if it is determined to be "YES" by the off operation, the process proceeds to step S2. The subsequent processing is the same as in the second embodiment.

As described above, according to the third embodiment, when the stop switch 4 is turned on, the microcomputer 9 sends a stop signal to the engine starter and then stops the power supply to the control unit of the microcomputer 9. After the process is completed and the start switch 3 is turned on and then turned off, 2
When the start switch 3 is turned on again within a second, a start signal is transmitted to the engine starter. Therefore, when the stop signal is transmitted, the determination step S5 is not passed, so that the power supply time to the microcomputer 9 can be shortened as compared with the second embodiment.

The present invention is not limited to the embodiments described above and shown in the drawings, but the following modifications are possible. In step S5, the time for accepting the ON operation of the start switch 3 or the stop switch 4 after the time measurement is started in step S2 is not limited to 2 seconds and may be changed appropriately.

The operation of the stop switch 4 as an activation switch is not limited to one ON operation, and for example,
If it is determined to be "YES" in step S1, the process may proceed to step S2 on condition that the ON operation is performed a predetermined number of times more than once. The predetermined number of ON operations may be performed within a fixed time, and the process may be terminated if the predetermined number of ON operations are not performed within the predetermined time. The start switch in the first embodiment may be the start switch 3. In this case, the determination step S1 is replaced with the determination step of "start switch off?", And when the start switch 3 is turned off, the process proceeds to step S2.

In the second embodiment, in step S1, "Y
If it is determined to be "ES", the process may proceed to step S2 on condition that the stop switch 4 is turned on a predetermined number of times more than once. The predetermined number of ON operations may be performed within a fixed time, and the process may be terminated if the predetermined number of ON operations are not performed within the predetermined time. Step S in the second embodiment
0 means between steps S1 and S2 or step S5
And S6 may be inserted.

In the third embodiment, in step S9, "Y
If it is determined to be “ES”, the process may proceed to step S2 on condition that the start switch 3 is turned on a predetermined number of times more than once. The predetermined number of ON operations may be performed within a fixed time, and the process may be terminated if the predetermined number of ON operations are not performed within the predetermined time. It may be applied not only to automobiles but also to general vehicles equipped with an engine starter. The airborne signal is not limited to electromagnetic waves such as microwaves, but electromagnetic induction signals, electrostatic induction signals, or optical signals may be used by appropriately changing the configuration of the transmission circuit.
