Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle indicator lamp controller capable of lighting an indicator lamp based on an external signal with a simple and inexpensive structure, and a vehicle lock confirmation system using the same.

[0002]

Background of the Prior Art invention In recent years, locking and unlocking of the door lock as the equipment of the motor vehicle non-contact and perform keyless entry device by remote control have become popular. By the way, when the keyless entry device is used to perform the locking / unlocking operation away from the automobile, it is necessary to confirm whether or not the locking / unlocking operation is performed according to the operation. In a vehicle in which the door knob can be confirmed through the door window, it can be confirmed by looking at the position of the knob, but it becomes difficult if the door knob is a little away from the vehicle, and it is completely impossible if the door knob cannot be seen through the door window. Therefore, various types of lock confirmation systems have been proposed, such as lighting a room lamp, instantly ringing a horn, and flashing a hazard. However, room lamps are difficult to check in the daytime, and horns can be a nuisance to others. Therefore, a lock confirmation system that uses blinking indicator lights (such as turn signal lamps or turn signal lights of vehicles) is often used. Has been done.

Conventional Locking Confirmation System (First Conventional Example) FIGS. 5 to 6 show a first conventional example of a locking confirmation system which blinks an indicator light by a signal (external signal) from such a keyless entry device. The indicator light control device is shown. This indicator light control device, as shown in FIG.
It is provided with a three-terminal flasher circuit 4 (indicator light controller) which is connected to the battery 2 via the ignition switch 1 and intermittently turns on the output to blink the indicator light 3. Based on the output, the turn signal switch 5 blinks either one of the indicator lights 3a or 3b, or the three-contact hazard switch 6 causes the indicator lights 3a on both the left and right sides to blink.
And 3b are blinked. When a signal (external signal) from the receiver of the keyless entry device is input, the three-contact type external input switch 7 is actuated, and all the indicator lights 3 are operated in the same manner as when the hazard switch 6 is operated. Was to blink.

That is, a three-terminal flasher circuit 4
6 is a circuit formed on one substrate. As shown in FIG. 6, a control circuit 11 integrated into an IC, an output on / off relay 12, a current detection resistor 13, and an oscillation circuit 14 are provided.
And a grounding resistance 15, and the terminals are the power supply terminal 1
6, output terminal 17, and ground terminal 18. Here, the power supply terminal 16 is, as shown in FIG. 5, the power supply side contact 6a of the ignition switch 1, the hazard switch 6 and the power supply side contact 7 of the external input switch 7 which are connected in parallel.
It is connected to the battery 2 via a, and further via a fuse 2a. The output terminal 17 includes a right side contact 5a of the turn signal switch 5, a right side contact 6b of the hazard switch 6, and an external input switch 7 which are connected in parallel.
Connected to the right indicator light 3a by the right contact 7b of
The left contact 5b of the turn signal switch 5, the left contact 6c of the hazard switch 6, and the left contact 7c of the external input switch 7 are connected to the left indicator lamp 3b.

Then, the control circuit 11 turns on / off the output of the OUT terminal at a predetermined cycle based on the oscillation frequency of the oscillation circuit 14 in a state where the power is input from the B terminal connected to the power supply terminal 16, and relays the output. It has a function to open and close 12 intermittently. Therefore, if the turn signal switch 5 is operated in a direction to close the right contact 5a while the ignition switch 1 is turned on, the right indicator light 3a
If the turn signal switch 5 is operated in the direction to close the left contact 5b, only the left indicator light 3b will blink.
Only flashes. When the hazard switch 6 is operated to close all the contacts 6a, 6b, 6c, or when all the contacts 7a, 7b, 7c of the external input switch 7 are closed by a signal from the receiver of the keyless entry device. , Regardless of the operating state of the ignition switch 1, the power supply terminal 16 of the flasher circuit 4 (control circuit 11
Since the power is supplied to the B terminal) and the output terminal 17 of the flasher circuit 4 is connected to the indicator lights 3a and 3b on both sides, all the indicator lights 3a and 3b blink.

A receiver (not shown) of the keyless entry device receives a lock or unlock command, or detects that the lock or unlock command actually locks or unlocks. A signal for activating the external input switch 7 is output, and the function of the receiver or the like is configured to stop the signal and automatically stop the blinking of the indicator light after a certain time elapses. The voltage on the secondary side of the resistor 13 is input to the control circuit 11 from the VS terminal, and the control circuit 11 detects the current value from the voltage drop of the resistor 13 and compares it with the reference current. Therefore, when it is determined that the indicator lamp is damaged and burned out, the blinking cycle (blinking rate) of the other indicator lamps is made faster than usual, and the driver of the vehicle is also warned of this. .

Conventional Lock Confirmation System (Second Conventional Example) FIGS. 7 to 8 show an indicator light control device in a second conventional example of the lock confirmation system which blinks the indicator light by a signal from the keyless entry device. This indicator light control device includes a 6-terminal flasher circuit 20, and a turn signal switch 55, a hazard switch 56, and an external input switch 57 are connected to the signal input side (low voltage side) of the flasher circuit 20.

It blinks.

That is, a 6-terminal type flasher circuit 2

And the diode 56b, or the left contact 57b of the external input switch 57, and is connected to the battery 2 side. Further, the right side output terminal 30 and the left side output terminal 31 are separately connected to the right side indicator light 3a or the left side indicator light 3b.

When the voltage of the R terminal connected to the right signal input terminal 33 is turned on in the state where the power is input from the B terminal connected to the power supply terminal 29, the control circuit 21 oscillates the oscillation circuit 24. With a predetermined period based on frequency,
When the output of the OUTR terminal is turned on and off to open and close the relay 22 for turning the right output on and off intermittently, and when the voltage of the L terminal connected to the left signal input terminal 34 is turned on,
At a predetermined cycle based on the oscillation frequency of the oscillation circuit 24, the OU
It has a function of turning on / off the output of the TL terminal to intermittently open / close the relay 23 for turning on / off the left output. The circuit of the control circuit 21 is configured so that this operation is continued unless the voltage of the R terminal or the L terminal is turned off.

Therefore, if the turn signal switch 55 is operated in a direction to close the right side contact 55a while the ignition switch 1 is turned on, the right side indicator light 3a.
When the turn signal switch 55 is operated in the direction to close the left contact 55b, only the left indicator light 3b blinks. Further, when the hazard switch 56 is operated to close the contact 56c, the right signal input terminal 33 and the left signal input terminal 34 (control circuit 21) of the flasher circuit 20 are irrespective of the operating states of the ignition switch 1 and the turn signal switch 55. R terminal and L
Since a voltage is applied to the terminals, all the indicator lights 3a and 3b blink. Further, when all the contacts 57a, 57b of the external input switch 57 are closed for a certain period of time by a signal from the receiver of the keyless entry device, the right signal of the flasher circuit 20 is output regardless of the operating states of the ignition switch 1 and the turn signal switch 55. Since the voltage is applied to the input terminal 33 and the left signal input terminal 34 for a certain period of time, all the indicator lamps 3

Invite. In particular, when the three-terminal flasher circuit 4 is used (in the case of the first conventional example), it is necessary to provide a large external input switch 7 having three large-current open / close contacts. , The number of wires also increases. Further, even when the 6-terminal type flasher circuit 20 is used (in the case of the second conventional example), an extra switch 57 having two contacts must be provided, which is compared with the case where the blinking for confirming locking is not performed. For example, the lock confirmation system will inevitably become larger.

(2) Since the hazard switches 6 and 56 are arranged separately from the flasher circuit and wired to the indicator light controller (flasher circuit), the wiring becomes complicated in this respect as well, and the assembly cost and the component cost are also increased. Was getting higher. In particular, when the 3-terminal flasher circuit 4 is used (in the case of the first conventional example), the large current switching contact is set to 3
Since it is necessary to provide a large-scale hazard switch 6 which is individually provided, the size of the entire system is increased and the number of wires is increased.

An embodiment of the present invention will be described below with reference to the drawings. It should be noted that, unless otherwise stated, the same components as those of the related art will be denoted by the same reference numerals and description thereof will be omitted. Configuration of First Embodiment FIGS. 1 and 2 are circuit diagrams showing an indicator light control device in a first embodiment of a lock confirmation system for a vehicle. This indicator light control device, as shown in FIG. 1, is a one-contact hazard switch 6 that does not use a diode as a hazard switch.
1, and the flasher circuit is characterized by including an 8-terminal flasher circuit 70 (indicator light controller). The flasher circuit 70 has the same basic configuration as the flasher circuit 21 of the second conventional example, but has a control circuit 71 (control means) having a function added as compared with the control circuit 21 of the second conventional example, and a first circuit. External input terminal 72, second external input terminal 73, and these terminals 7
It is characterized in that it has resistances 74 and 75 for signal input from 2, 73. Then, the first external input terminal 72 is connected to the battery side via the hazard switch 61,
The second external input terminal 73 is connected to the ground via a transistor 81 that is turned on / off by a signal from the receiver in the keyless entry device.

The control circuit 71, like the control circuit 21,
When the input signal of the EXT1 terminal connected to the first external input terminal 72 is turned on, it is the R terminal or the L terminal.
Regardless of the input signal from the terminal, the OUTR terminal and the OUTL terminal have a predetermined cycle based on the oscillation frequency of the oscillation circuit 24.
It has a function (hazard blinking control function) of turning on and off the output of the terminal to intermittently open and close the relay 22 for turning on the right side output and the relay 23 for turning on the left side output. The circuit configuration is such that this operation can be continued unless the input signal of the EXT1 terminal is turned off.

When the input signal of the EXT2 terminal connected to the second external input terminal 73 is turned on, the control circuit 71 changes the oscillation frequency of the oscillation circuit 24 regardless of the input signal from the R terminal or the L terminal. Based on a predetermined cycle, OUTR
It has a function (external control function) of performing an operation of turning on / off the outputs of the terminals and the OUTL terminals to intermittently open / close the relay 22 for turning on / off the right side output and the relay 23 for turning on / off the left side output for a predetermined time. In this case, EXT2
The signal form of the terminal is so-called low voltage active,
When this terminal becomes the ground voltage, the signal is treated as ON. (Note that in this case, other terminals such as the EXT1 terminal are active at high voltage.)

Then, in this case, the control circuit 71 uses the EXT
It has a function of discriminating the mode (for example, the time width in which it is on) of the input signal of the two terminals, and when the relay 22 and the relay 23 are intermittently opened and closed according to the mode of the input signal. It has a function (signal identification function) of changing the time condition, that is, the cycle or length of the opening / closing operation (length of ON or OFF). The time condition for intermittently opening and closing the relay 22 and the relay 23 when the input signal of the EXT2 terminal is turned on is different from that when the input signal from the R terminal, the L terminal or the EXT1 is turned on. It may be set to etc.

The keyless entry device (not shown) receives a wireless signal (infrared signal) from a transmitter operated by a driver of an automobile or the like by a receiver and outputs a lock signal or an unlock signal. Although it is a well-known device that automatically locks or unlocks the vehicle door (including the trunk etc.) after determining whether or not it is, in the vehicle door lock confirmation system of the present embodiment, the base electrode of the transistor 81 described above is used. In addition, it has a function of applying a pulse signal (driving voltage) having a different pulse width, for example, in the case of locking and the case of unlocking. The keyless entry device may drive the transistor 81 at a timing of outputting the pulse signal when a lock or unlock signal from the transmitter is input to the receiver, or the receiver may be locked or unlocked. After receiving the unlocking signal, the pulse signal may be output when it is detected that the locking or unlocking operation is actually performed.

Operation of First Embodiment Next, the operation of the lock confirmation system of the first embodiment described above will be described. In the above configuration, if the turn signal switch 55 is operated in the direction to close the right side contact 55a with the ignition switch 1 turned on, only the right side indicator light 3a blinks as in the second conventional example. If the turn signal switch 55 is operated in the direction to close the left contact 55b, only the left indicator lamp 3b blinks. Further, when the hazard switch 61 is operated to close its contact, the input signal of the first external input terminal 72 (the EXT1 terminal of the control circuit 71) of the flasher circuit 70 is turned on, and the relay 22 and the relay are controlled by the control circuit 71. Since 23 opens and closes intermittently, all indicator lights 3a,
3b will blink.

When the keyless entry device is locked or unlocked, the signal from the receiver causes the transistor 81 to perform a switching operation for a predetermined time, and the second external input terminal 73 (control circuit 71 of the flasher circuit 70). A pulse signal of a predetermined mode is input to the EXT2 terminal of the. Then, the control circuit 71 discriminates its type (that is, whether it is a locking operation or an unlocking operation) from the time width of the input signal, and the relay 22 and The relay 23 is opened and closed intermittently. Therefore, all the indicator lights 3a and 3b will blink in a cycle or the like according to the type of locking operation or unlocking operation,
A person who operates the keyless entry device can easily confirm that the locking or unlocking operation has been performed from a position away from the vehicle.

As described above, according to the lock confirmation system of the first embodiment, the normal operation of the indicator lamp 3 (turn signal and hazard operation) can be performed, and the vehicle can be locked or unlocked by the keyless entry device. The confirmation when performed can be easily performed by distinguishing between locking and unlocking by blinking the indicator light, which greatly contributes to prevention of erroneous operation of the keyless entry device. Moreover, as parts for performing the locking / unlocking notification control, the external input switch 7 in the first conventional example, the external input switch 57 in the second conventional example,
Since the parts having a large number of wires such as the diodes 56a and 56b are unnecessary, it is possible to reduce the size, reduce the number of parts, and reduce the number of parts assembling steps and wiring steps at the time of assembly. It is possible to effectively use the installation space and reduce the cost.

In the first embodiment, the flasher circuit 70 and the control circuit 71 in the flasher circuit 70 are provided with dedicated external input terminals 72 and EXT1 terminals for hazard control. 2 of the hazard switch
If the secondary side is connected to the secondary side of the turn signal switch 55, these terminals are unnecessary and the circuit in the control circuit 71 for hazard control connected to the EXT1 terminal is also unnecessary. In this case, in order to prevent so-called current sneak, a diode is provided on the secondary side of the hazard switch as in the second conventional example, or a two-contact type hazard is used as in a second example described later. It is necessary to use a switch. Further, the hazard switch 61 does not necessarily have to be provided separately from the indicator light controller, and even when the EXT1 terminal for hazard control is provided, a one-contact type hazard switch is connected between the EXT1 terminal and the power supply terminal 29. Then, as in the second embodiment described later, the hazard switch can be integrated with the indicator lamp controller.

Configuration of Second Embodiment Next, a second embodiment of the present invention will be described. The same components as those in the first embodiment are designated by the same reference numerals and the description thereof will be omitted. 3 to 4 are circuit diagrams showing an indicator light control device in a second embodiment of the vehicle door lock confirmation system. This indicator light control device includes a 7-terminal flasher circuit 90, that is, a flasher circuit 90 provided with only a terminal 73 for locking / unlocking notification function as an external input terminal.
Equipped with a flasher circuit 9 as a hazard switch
It is characterized in that it has a two-contact type hazard switch 95 integrally provided on the substrate of No. 0.

As shown in FIG. 4, the flasher circuit 90 has a control circuit 91 having only an EXT terminal connected to the external input terminal 73 as an external input terminal. In this control circuit 91, the EXT terminal functions in the same manner as the EXT2 terminal in the control circuit 71 in the first embodiment described above. As shown in FIG. 4, the hazard switch 95 has a right-side contact 95a and a left-side contact 95b, which are connected to open and close between the power supply terminal 29 and the right-side signal input terminal 33 or the left-side signal input terminal 34, respectively. The contact points 95a and 95b are simultaneously operated.

Operation of the Second Embodiment Also in the second embodiment, if the turn signal switch 55 is operated in the direction to close the right contact 55a while the ignition switch 1 is turned on, only the right indicator lamp 3a is displayed. Blinks, and when the turn signal switch 55 is operated in the direction to close the left contact 55b, only the left indicator lamp 3b blinks. Also, hazard switch 95
When the respective contacts 95a and 95b are closed by operating, the both the right side input terminal 33 and the left side input terminal 34 (R terminal and L terminal of the control circuit 91) of the flasher circuit 90 are turned on, and by the control of the control circuit 91. Since the relay 22 and the relay 23 open and close intermittently, all the indicator lights 3a,
3b will blink.

When the keyless entry device is locked or unlocked, the signal from the receiver causes the transistor 81 to perform a switching operation for a predetermined time, and the external input terminal 73 of the flasher circuit 90 (EXT of the control circuit 91). A pulse signal of a predetermined mode is input to the (terminal). Then, the control circuit 91 discriminates its type (that is, whether it is a locking operation or an unlocking operation) from the time width of the input signal or the like, and at a cycle or the like according to the type of this signal,
The relay 22 and the relay 23 are opened and closed intermittently. For this reason, all the indicator lights 3a and 3b blink in a cycle or the like according to the type of the locking operation or the unlocking operation, and the person who operates the keyless entry device indicates that the locking or unlocking operation has been performed. It can be easily confirmed from a position away from the vehicle.

As described above, according to the lock confirmation system of the second embodiment and the lock confirmation system using the lock confirmation system,
Normal operation of the indicator light 3 (turn signal and hazard operation) is possible, and confirmation when the vehicle is locked or unlocked by the keyless entry device is easy by distinguishing between locking and unlocking by blinking the indicator light. As a result, it can greatly contribute to prevention of erroneous operation of the keyless entry device. Moreover, as the parts for performing the locking / unlocking notification control, the parts having a large number of wires such as the external input switch 7 in the first conventional example and the external input switch 57 in the second conventional example are unnecessary, and the two-contact type Since the hazard switch 95 is integrated in the flasher circuit 90, the diodes 56a, 5 for preventing current sneak
6b is not necessary, and independent wiring or assembly of the hazard switch is not required when assembling the parts, so the number of parts, wiring man-hours, and assembly man-hours can be further reduced, and further cost reduction of the lock confirmation system or vehicle etc. Can be achieved.

The present invention is not limited to the above-mentioned first and second embodiments, but may have various modes. For example, the indicator light controller of the present invention is not limited to being applied to the lock confirmation system, but may be applied to turn on the indicator light for confirmation of other operation in a vehicle or the like. In the first and second embodiments described above, the mode of the input signal from the keyless entry device is made different between the case of locking and the case of unlocking, and on the basis of this, the indicator light distinguishes between locking and unlocking. The control circuit 71 has a signal identification function for blinking 3
Although it is provided in 91, it may be configured not to distinguish between locking and unlocking as described above, and in some cases, the notification function works only when locking or the notification function works only when unlocking. You can also

Furthermore, for example, the blinking cycle of the indicator light when notifying the locking / unlocking may be the same as in the case of turn signal or hazard. By doing so, the circuit configuration can be realized by an extremely simple modification to the second conventional example. That is, in principle, one external input terminal connected to each of the R terminal and the L terminal via a diode is provided in the control circuit, a hazard switch is connected to this external input terminal, and It may be configured to input a signal. However, in this case, the keyless entry device is configured to continue to output a signal until the blinking time for informing the locking or unlocking has elapsed, and the mode of the signal from the keyless entry device is also a so-called high voltage active. Need to be unified.

[0045]

According to the indicator lamp controller of the first aspect, the indicator lamp can be turned on by an external signal by an external control function of the control circuit with a simple structure without providing a separate switch or the like. As a result, it is possible to downsize the vehicle lock confirmation device to which the indicator light controller is applied, reduce the number of parts, reduce the wiring man-hours and the assembly man-hours, and thus effectively use the installation space in the vehicle and reduce the cost.

Moreover, according to the indicator lamp controller of the second aspect, since the control means is provided with the signal identification function, the mode of the indicator lamp lighting by the external signal is made to be meaningful to the driver of the vehicle or the like. It becomes convenient and convenient. For example, when the external control function of the indicator light controller is used to confirm the operation in the vehicle, the driver etc. can be surely and easily informed that the corresponding operation has been performed by turning on the indicator light in a different mode for each type of operation. I can inform you.

Further, according to the indicator lamp controller of the third aspect, since the hazard switch for inputting the signal for constantly turning on the indicator lamp to the control means is integrally provided, when the hazard switch is provided independently. Compared to,
The man-hours for assembling parts into the vehicle and the wiring man-hours are reduced,
Further cost reduction of vehicles etc. can be achieved.

According to another aspect of the vehicle lock confirmation system of the present invention, a signal is input to the external input terminal in response to the lock operation of the vehicle door, and when the lock operation is performed. Since the indicator light is configured to be turned on in a predetermined manner, the indicator light is turned on in a predetermined manner when the vehicle door is locked, so that the driver etc. can reliably and easily perform the locking operation.
