DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
For remote control devices for vehicles to enable remote control such as stop, door lock / unlock, burglar alarm set / reset, burglar alarm monitoring, trunk opener, auto light cancel, etc. Also, the present invention relates to a vehicle remote control device capable of expanding the settable vehicle types.

[0002]

2. Description of the Related Art As a vehicle remote control device for starting / stopping an engine, locking / unlocking a door lock, setting / resetting a burglar alarm, monitoring a burglar alarm, and remotely controlling a trunk opener, see, for example, Japanese Patent Application Laid-Open No. 54-1979. Japanese Patent Application Laid-Open No. 49,721 and Japanese Utility Model Application Laid-Open No. Sho 62-150,585 are known. These devices transmit weak radio waves such as infrared rays and FM waves from a portable transmitter, control a receiver provided on the vehicle side, start the engine, warm up the engine, and adjust the temperature in the room beforehand. It is used for

[0003] Such a remote control device is composed of a transmitter carried by an operator and a receiver mounted on a vehicle. Various signals from the vehicle are input to the receiver. I have.

For example, when starting the engine by remote control, it is determined whether or not the transmission is in a parking position and whether or not a side brake is applied so that a runaway of the vehicle does not occur. The output is executed. In addition to these signals, a door and engine hood opening detection signal is input, and if the door or engine hood is open and someone is near the room or engine room, safety is ensured so as not to start the engine. Is secured.

When the receiver of the remote control device is mounted on the vehicle, the output terminal of the electrical component on the vehicle is connected to the input terminal of the receiver.

[0006]

By the way, when various signals from the vehicle side are input to the receiver side, for example, when it is desired to take in the signal of the parking position of the automatic transmission vehicle, wiring of the indicator of the instrument panel is performed. Etc. are shared, but depending on the vehicle, even when the vehicle is at the same parking position, the "H
There are those that output an "i signal" and those that output a "Lo signal".

Therefore, when the receiver of the conventional remote control device for a vehicle is mounted, it is first determined which signal the vehicle outputs, and then the internal changeover DIP switch is set to the type. Was set to. That is,
After setting the dip switch to either one and connecting the wires, the start signal is sent from the transmitter, and it is determined whether or not the initially set dip switch is appropriate by checking whether the engine actually starts. Was.

Further, the parking position of the automatic transmission is not limited to being taken from the above-described wiring of the indicator, and often uses the wiring from the inhibitor switch in common. For example, there is a vehicle type for which a signal regarding the parking position is not sent to the indicator.

[0009] The selection of whether to output the parking position as an indicator or an inhibitor switch depends on the simplicity of the connection work, the type of the vehicle, and the like. However, there has been a problem that the number of parts is increased because there is no receiver that can flexibly cope with the receiver and a receiver corresponding to the type of vehicle to be mounted is prepared. In addition, since the type of the output signal of the vehicle is confirmed by actually starting the engine as described above, the mounting operation is extremely complicated.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problems of the prior art, and has as its object to provide a vehicle remote control device that can be easily installed and installed and can expand the number of vehicles that can be set. I do.

[0011]

In order to achieve the above-mentioned object, a remote control device for a vehicle according to the present invention is provided on a vehicle (10) and connected to a vehicle-mounted sensor (11) and a vehicle-mounted device (12). A portable transmission device (30) for transmitting an operation signal to the reception device, based on an operation signal from the transmission device to the reception device and a vehicle state from the vehicle-mounted sensor. The in-vehicle device (1
In the remote control device for a vehicle that remotely controls 2), the receiving device (20) includes a mode switch (26) corresponding to a signal type from the vehicle-mounted sensor (11) and a mode by the mode switch (26). The in-vehicle sensor (1
It is characterized by having a judgment circuit (25) for judging whether or not the signal type is suitable for the signal type from 1), and a display means (24) for showing a judgment result by the judgment circuit (25).

When the vehicle remote control device of the present invention is mounted on a vehicle to perform a connection work with the vehicle-mounted sensor and the vehicle-mounted device, the type of signal output from the vehicle-mounted sensor of the vehicle is determined by the type of the receiving device. Although it is necessary to set the mode switch to an appropriate mode, in the remote control device of the present invention, a determination circuit that determines whether the mode by the mode switch is suitable for the type of signal from the on-board sensor, Since there is provided a display means for displaying the determination result, the mode switch is set arbitrarily, and in this state, the detection operation by the on-vehicle sensor is confirmed while looking at the display means.

For example, in response to a transmission parking position detection signal, the shift lever is operated between the parking position and other positions, and the change in the display means at this time is observed. If the mode of the mode switch is appropriate, the display means indicates so, and the operator can immediately recognize that the mode of the mode switch is appropriate. Conversely, if the display means does not change at all even if the shift lever is operated, the mode is inappropriate, so that another mode is set and the shift lever is operated again. By repeating such operations sequentially, an appropriate mode can be set immediately.

In the above invention, the specific configuration of the vehicle-mounted sensor or the vehicle-mounted device is not particularly limited, and the present invention can be applied to various vehicle-mounted sensors and vehicle-mounted devices.

According to a second aspect of the present invention, in the vehicle remote control device, the on-vehicle sensor (11) is a sensor for detecting whether a shift lever of a vehicle transmission is input to a parking position, and the determination circuit ( 25) A signal from the vehicle-mounted sensor when the shift lever is input to the parking position is a first type signal, the mode switch is set to the first mode, and the shift lever is moved to the parking position. When the shift lever is input to a position other than the parking position, it is detected that the position is other than the parking position, and when the shift lever is again input to the parking position, it is detected that the parking position is set, the fact is output to the display means. Then, a first processing routine (S3, S30) for storing the first mode as a mode suitable for the type of signal from the vehicle-mounted sensor. 36, S60), the signal from the vehicle-mounted sensor when the shift lever is input to the parking position is a second type signal other than the first type signal, and the mode switch is in the second mode. The shift lever is set to a position other than the parking position when the shift lever is input to a position other than the parking position. When the shift lever is again input to the parking position, the shift position is determined to be the parking position. If it is detected, a second processing routine (S4, S40-46, S4) that outputs that fact to the display means and stores the second mode as a mode suitable for the type of signal from the on-vehicle sensor.
60) and the signal from the vehicle-mounted sensor when the shift lever is input to the parking position is a third type signal other than the first and second types of signals, and the mode switch is the first type signal. And any one of the second mode is set, and when the shift lever is input to a position other than the parking position, it is detected that the position is other than the parking position, and the shift lever is input again to the parking position. When a parking position is detected, a message to that effect is output to the display means, and the third mode is stored as a mode suitable for the type of signal from the vehicle-mounted sensor (S5, S50). ~ 5
5, S60).

In this remote control device, the type of output signal of the on-vehicle sensor, here, the sensor for detecting whether or not the shift lever of the transmission is input to the parking position, is a Hi signal (first signal) or a Lo signal (first signal). 2) or any other signal, such as an output signal from an inhibitor switch (third signal), even if it differs depending on the vehicle type, if it is the first signal. This can be automatically determined by the first processing routine and stored, and then, if the signal is not the first signal, automatically determined and stored as the second signal by the second processing routine. Can be
Further, when neither of the first and second signals is used,
The third processing routine can automatically determine whether the signal is the third signal and store the signal.

Therefore, when the remote control device of the present invention is mounted on a vehicle, an appropriate mode can be set only by operating the shift lever and checking the display means.
Inconveniences such as malfunctions due to connection errors can be prevented. In addition, an in-vehicle sensor that detects the parking position is a Hi signal,
Whichever type of Lo signal is output, or if it becomes necessary to use other sensors, it is possible to cope with it. be able to.

According to the second aspect of the present invention, the on-board sensor is a sensor for detecting the parking position and is preferably used mainly for remote control of starting / stopping of the engine. The target and the detection signal are not particularly limited, and can be applied to, for example, starting / stopping an engine, locking / unlocking a door, setting / resetting a burglar alarm, monitoring a burglar alarm, a trunk opener, and auto light canceling. The operation signal transmitted from the transmitting device to the receiving device is not particularly limited, and various wireless signals such as an infrared signal and a high-frequency radio signal can be used.

[0019]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an entire vehicle remote control device according to an embodiment of the present invention, and FIG. 2 is a flowchart showing a procedure for registering a parking position according to the embodiment.

First, as shown in FIG. 1, the vehicle remote control device according to the present embodiment is mounted on a vehicle 10 and receives a signal relating to the vehicle state from a plurality of vehicle-mounted sensors 11 and receives one or more signals. It comprises a receiving device 20 for transmitting an operation command signal to the in-vehicle device 12, and a transmitting device 10 carried by the user and transmitting various operation signals to the receiving device 20.

The on-vehicle device 12 to be operated is not particularly limited. However, in the remote control device of the present embodiment, starting / stopping of an engine and locking / unlocking of a door lock are to be operated. The remote operation related to the start / stop of the engine is performed, for example, by operating the engine remotely from an indoor place in the early morning of winter to perform warm-up operation and indoor heating in advance to enhance driving performance and comfort during riding. Used for Locking and unlocking the door lock is extremely convenient because the door lock can be locked and unlocked without inserting the key into the key cylinder, especially at night or when carrying luggage in both hands, or opening and closing the door frequently. If the effect is large.

The transmitting device (so-called remote controller) 30 of the present embodiment is provided with operation buttons 32 and 33 on a main body 31, and an antenna 34 for transmitting operation signals is provided so as to be extendable and contractible. The operation button 32 is a button for starting and stopping the engine, and the operation button 33 is a button for locking and unlocking the door lock. Although not particularly limited, in the present embodiment, these operation buttons 32, 3
Reference numeral 3 denotes a switch structure that is turned ON only when pressed, and turned OFF when the button is released.

In the transmission device 30, signals of the operation button 32 for starting / stopping the engine and the operation button 33 for locking / unlocking the door are input to a control circuit (for example, an electronic circuit or a microcomputer) incorporated in the main body. It is determined whether the operation buttons 32 and 33 are ON or OFF. The ON signal from the operation button 32 or 33 is sent from the control circuit to a high frequency transmission circuit built in the main body, where it is modulated into a predetermined high frequency radio wave and transmitted from the antenna 34. An identification code signal or the like dedicated to the transmission device 30 is encoded in the high-frequency signal, and only the reception device 20 that matches the identification code signal receives the operation signal.

On the other hand, the receiving device 20 mounted on the vehicle side
Is a high-frequency receiving circuit 22 for receiving a high-frequency electric wave received by the antenna 21; and a first signal for demodulating a high-frequency signal received by the high-frequency receiving circuit 22 into a control signal.
And a second control circuit 25 that receives a control signal from the first control circuit 23 and sends an operation signal to an output unit 28 while taking into account the vehicle situation from the input unit 27.

Although not particularly limited, the antenna 21, the high-frequency receiving circuit 22, the first control circuit 23, and the L
The ED 24 is installed on the rear parcel of the vehicle, behind a rearview mirror, or the like.

The in-vehicle sensor 11 is a plurality of sensors for detecting, for example, a parking position of a transmission shift lever, a parking brake (side brake), a door position, an engine hood position, an engine start signal, a door lock state, and the like. Device 3
When an operation signal from 0 is received, the operation signal is sent to the second control circuit 25 via the input unit 27 to confirm whether the operation is in a state without any problem or to confirm execution of the operation.

In order to remotely control the start / stop of the engine, signals of a parking position of a shift lever of a transmission, a parking brake (side brake), a door position, an engine hood position, and an engine start signal are used. The signal of the door lock state is used to remotely control the locking and unlocking of the door lock.

The parking position of the shift lever of the transmission is displayed on the indicator on the instrument panel depending on the type of vehicle, so that the wiring of the indicator is shared. Further, in a vehicle type in which the shift lever indicator is not provided on the instrument panel, the signal from the inhibitor switch is shared.
If there is a shift lever indicator on the instrument panel, the wiring is easy to use and it is used with priority.However, in the case of models without this, the inhibitor switch is replaced with the manual valve lever of the automatic transmission. This sensor is used to detect the position of the vehicle, and is provided in all vehicles so as not to operate the starter except at the neutral or parking position.

When the indicator signal of the instrument panel is shared as a sensor for detecting the parking position of the shift lever, a sensor that outputs a Hi signal when the vehicle is in the parking position depending on the vehicle type (a Lo signal when the vehicle is not in the parking position); There is one that outputs a Lo signal (Hi signal when other than the parking position). Therefore, the second control circuit 2 of the receiving device 20
5 is provided with a mode switch 26 composed of a dip switch, so that the parking position can be detected as a result whether the signal from the parking position sensor input via the input unit 27 is a Hi signal or a Lo signal. Mode can be switched as described above. The mode setting by the mode switch 26 is initially set when the remote control device of the present embodiment is mounted on a vehicle.

In setting the mode by the mode switch 26, the second control circuit 25 is used to easily determine whether the parking position sensor of the vehicle outputs a Hi signal or a Lo signal. And an LED lamp 24 for indicating a result of the determination is provided in, for example, the first control circuit 23. However, this LED lamp 2
The arrangement of 4 is not limited at all, and may be any position as long as it is easily visible to a worker who is integrated with or mounting the antenna.

Next, a procedure for registering a parking position will be described. First, the receiving device 20 is mounted on a vehicle, and a plurality of input terminals constituting the input unit 27 are respectively provided with a parking position of a transmission shift lever, a parking brake, a door position, an engine hood position, an engine start signal, a door lock state, and the like. Connect multiple sensors to be detected. At this time, an engine starter motor and a door lock actuator are connected to a plurality of output terminals constituting the output section 28, although not always necessary. In the following flow, only the procedure for registering the parking position will be described.

In this state, the shift lever of the transmission is put into the parking position, the ignition is turned on by the engine starter key, and the engine is started (step 2). As a result, a signal from the parking position sensor is input to the second control circuit 25 via the input unit 27. In Steps 3 to 5, whether the signal at this time is a Hi signal or a Lo signal is determined. , Or any other inhibitor switch is a signal from the input terminal to which it is connected.

If it is determined in step 3 that the input signal is a Hi signal, the flow advances to step 31 to determine whether or not the DIP switch (mode switch) 26 is in the ON mode. .
Next, the operator moves the shift lever from the parking position to another position, for example, a back position. This position may be any position other than the parking position. As a result, the output signal from the parking position sensor becomes L
Since the signal changes to an o signal, this is confirmed in steps 32 and 33, and then the LED lamp 24 flashes once (step 34). The operator operates the shift lever from the parking position to the back position while watching the LED lamp 24, and checks whether the LED lamp 24 blinks once.

If the LED lamp 24 blinks once, the shift lever is moved to the parking position again, and in step 35, it is determined whether or not the output signal from the parking position sensor changes from the Lo signal to the Hi signal. , The LED lamp 24 is turned on and off twice (step 36). At this time, the operator operates the shift lever from the back position to the parking position while watching the LED lamp 24, and confirms whether the LED lamp 24 blinks twice.

Finally, since the currently set mode of the dip switch 26 ("ON" mode in step 31) is appropriate, this is stored (registered) in step 60.

Even if the signal from the parking position sensor is a Hi signal, if the DIP switch 26 is set to the OFF mode, step 31 is executed.
, The LED lamp 24 does not blink at all even if the operator moves the shift lever. This allows the operator to recognize that the currently set mode of the dip switch 26 is different, and switches the mode from the OFF mode to the ON mode.
Switch to the mode and operate the LED
Check that the lamp 24 is blinking.

On the other hand, if the signal from the parking position sensor input to the second control circuit 25 via the input unit 27 is a Lo signal in Steps 3 to 5 for different vehicle types, Step 40 and Step 40 Proceeding to step 41, it is determined whether or not the dip switch (mode switch) 26 is in the OFF mode. Next, the operator moves the shift lever from the parking position to another position, for example, a back position. This position may be any position other than the parking position. As a result, the output signal from the parking position sensor changes from the Lo signal to the Hi signal up to that point. After confirming this in steps 42 and 43, the LED lamp 24 flashes once (step 4).
4). The operator operates the shift lever from the parking position to the back position while watching the LED lamp 24, and checks whether the LED lamp 24 blinks once.

If the LED lamp 24 flashes once, the shift lever is moved to the parking position again, and in step 45, it is determined whether or not the output signal from the parking position sensor changes from the previous Hi signal to the Lo signal. , The LED lamp 24 is turned on and off twice (step 46). At this time, the operator operates the shift lever from the back position to the parking position while watching the LED lamp 24, and confirms whether the LED lamp 24 blinks twice.

Finally, since the currently set mode of the dip switch 26 ("OFF" mode in step 41) is appropriate, it is stored (registered) in step 60.
I do.

Even if the signal from the parking position sensor is a Lo signal, if the setting of the dip switch 26 is set to the ON mode, the operation is returned as it is in step 41, so that the operator can shift the shift lever. Does not blink the LED lamp 24 at all. This allows the operator to recognize that the currently set mode of the dip switch 26 is different, so that the mode is switched from the ON mode to the OFF mode, and the LED is operated again by the above-described procedure. Check that the lamp 24 is blinking.

By the above procedure, the parking position signal from the indicator on the instrument panel becomes Hi.
A signal or a Lo signal can be automatically set, but if it is neither signal, the signal from the inhibitor switch is confirmed in step 5, and if it is input, the process proceeds to step 50. In step 50, the Lo signal from the inhibitor switch (the signal output from the inhibitor switch is a Lo signal) is confirmed, and when the operator moves the shift lever from the parking position to another position, for example, the back position, Since the output signal from the inhibitor switch changes from the Lo signal to the Hi signal so far, this is confirmed in steps 51 and 52, and the LED lamp 24 flashes once (step 53). The operator operates the shift lever from the parking position to the back position while watching the LED lamp 24, and checks whether the LED lamp 24 blinks once.

If the LED lamp 24 flashes once, the shift lever is moved to the parking position again, and in step 54, it is determined whether or not the output signal from the inhibitor switch changes from the previous Hi signal to the Lo signal. If it has changed, the LED lamp 24 is
It flashes twice (step 55). At this time, the worker
While watching the LED lamp 24, operate the shift lever from the back position to the parking position, and
Check whether the lamp 24 flashes twice.

Finally, since the currently set state is appropriate, it is stored (registered) in step 60.

Incidentally, once the mode of the dip switch 26 is registered in the memory in the above-described procedure, an error is displayed when the dip switch 26 is next switched. (Step 1 → Step 80 → Step 82). On the other hand, if the signal from the inhibitor switch is not a Lo signal in step 50, the process returns in steps 70 to 72 as it is.

The embodiments described above are described for facilitating the understanding of the present invention, and are not described for limiting the present invention. Therefore, each element disclosed in the above embodiment is intended to include all design changes and equivalents belonging to the technical scope of the present invention.

For example, the display means of the present invention may employ a buzzer or the like in addition to the LED lamp 24.

As described above, according to the present invention, a judgment circuit for judging whether a mode by a mode switch is suitable for a signal type from a vehicle-mounted sensor, and a display showing a judgment result by the judgment circuit. Means and
It is possible to automatically set an appropriate mode simply by operating the shift lever and checking the display means, and it is also possible to simultaneously prevent malfunction such as malfunction due to incorrect connection.

Further, even if the on-vehicle sensor for detecting the parking position is of a type that outputs either a Hi signal or a Lo signal, it is possible to cope with the need to use other sensors. One type of remote control device can be mounted on a vehicle having a different specification.
