However, the answer-back system of the keyless entry device for a vehicle includes a flasher unit 3 for blinking the lamps 1 and 2.
Since the composite unit 6 that combines the functions of
There is a problem that the control is complicated and expensive.
Also, when compared with a vehicle of a grade to which the keyless entry device is not applied, the wiring of the switches 4 and 5 and the lamps 1 and 2 is greatly different, so that even in the same vehicle type, the wiring harness to be wired cannot be shared. Therefore, it is necessary to manufacture two types of wire harnesses, and there is a problem that the cost increases. Furthermore, when a vehicle without a keyless entry device and / or an answerback system is selected at the time of purchase of the vehicle, if these devices are mounted later, there is a problem that the cost burden on the user becomes extremely high. is there.

It is an object of the present invention to provide an answerback system for a keyless entry device for a vehicle which enables an existing flasher unit to be used and which is inexpensive even if a function is added later.

[0014]

In order to solve the above-mentioned problems, an answer back system for a keyless entry device for a vehicle according to the present invention comprises a left and right direction indicating lamps provided on a vehicle, an ignition power supply or a battery power supply. A flasher unit that intermittently supplies power to the lamp, a turn switch that is connected between the lamp and the flasher unit, and that allows power to be supplied to one of right and left predetermined lamps, and the battery. A power switch and a flasher unit are connected so as to be able to conduct electricity, a hazard switch that enables electricity to be supplied to the left and right lamps, and a keyless entry device that locks or unlocks a vehicle door lock device by remote control,
When the keyless entry device is locked or unlocked, the answerback system of the vehicular keyless entry device operates a predetermined lamp.

According to the answer back system, in the conventional signal device, a first switching element is provided between the flasher unit and the switch, and a second switching element for connecting a battery power supply and left and right lamps is turned on. The answerback is performed by performing the off control. Therefore, the keyless entry device does not require any signal device functions other than answerback. Therefore, the control is simplified. Further, in the wiring of a car of a grade to which the keyless entry device is not applied, since only two switching elements are added, the same wire harness can be shared.

In the answer back system, it is preferable that the first switching element is a relay.

[0017]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 shows an answer back system for a keyless entry device for a vehicle according to the present invention. This answer-back system has a keyless entry unit and a keyless entry unit 16 in the conventional signal device shown in FIG. 2 to which the answer-back system is not applied. The configuration of the conventional signal device is denoted by the same reference numeral, and the detailed description is omitted.

The first switching element comprises a normally closed relay 10 which is interposed between the flasher unit 3 and the switches 5b and 5c of the turn switch 4 and the hazard switch 5. The switch 11 of the relay 10 is a two-position switch, and its normally closed contact 11 a is connected to the flasher unit 3.
And the common terminal 11c is connected to the switches 5b and 5c of the turn switch 4 and the hazard switch 5. The coil 12 of the relay 10
One end is connected to the battery power supply B, and the other end is connected to the keyless entry unit 16. When the electric power of the battery power supply B is supplied to the coil 12, the switch 11 is switched to the normally open contact 11b.

The second switching element comprises a pair of relays 13 capable of supplying a large amount of current, and connects the battery power source B to the left and right lamps 1 and 2. The relay 13 includes two normally open switches 14a and 14b. One of the connection terminals is connected to the battery power source B, and the other connection terminal is connected to the left lamp 1 and the right lamp 2. ing. The coil 15 of the relay 13 has one end connected to the battery electrode B and the other end connected to the keyless entry unit 16. And this coil 15
The switch 14a, 14b is configured to switch to the contact side by supplying the power of the battery power supply B to the power supply.

The keyless entry unit 16 of this embodiment is connected to the battery power source B via the coils 12 and 15 of the relays 10 and 13 and to the electric actuator of a well-known door lock device. Then, as before, the user points the remote control at the vehicle,
When a locking or unlocking signal is received by operating a locking or unlocking switch, the door lock device is locked or unlocked based on the signal.

In this embodiment, the door lock device is locked or unlocked, and the relay 10 cuts off the power supply to the flasher unit 3 and the switches 5b and 5c of the turn switch 4 and the hazard switch 5. . Further, by operating the lamps 1 and 2 by the relay 13, an answer back for notifying the user of the locking or unlocking state is performed. In this answerback, the number of blinks or the blink cycle of the lamps 1 and 2 differs between the locking operation and the unlocking operation by the keyless entry unit 16.

Specifically, the hazard switch 5 is turned off.
When the signal for executing answer back is output from the keyless entry unit 16 in the state of
0 and 13 are turned on. By turning on and off the relay 13 intermittently, the left and right lamps 1 and 2 are turned off.
Is powered and flashes.

At this time, if the turn signal switch 4 is turned on so as to blink one of the lamps 1 and 2, the relay 10 opens the normally closed contact 11a and closes the normally open contact 11b. Therefore, the power of the battery power supply B does not flow back to the ignition power supply IG via the turn signal switch 4, the relay 10, the flasher unit 3, and the hazard switch 5.

In a state where the answer back is not operated, the relay 10 is connected to the normally closed contact 11a, and when the user operates the turn switch 4 or the hazard switch 5, the operation is the same as the conventional one. I do.

The answer-back system of the keyless entry device of the present invention is not limited to the above configuration. For example, in the above embodiment, the battery power source B
Although the relay 13 is applied as a second switching element for connecting the power supply and the lamps 1 and 2, the power supply transistor may be used. Similarly, the flasher unit 3
The first switching element provided between the switch and the switches 4 and 5 may also be constituted by a transistor. That is, the switching element can be applied as long as it is a known element that can be switched on and off.

[0026]

As is apparent from the above description, the answer back system for a keyless entry device for a vehicle according to the present invention differs from the conventional signal device in that a first switching element is interposed between a flasher unit and a switch. An answer back is performed by controlling on / off of a second switching element that connects a battery power supply and left and right lamps.

Therefore, the keyless entry device does not require any signal device functions other than answerback.
Therefore, the control is simplified, and it can be prevented from becoming expensive. Further, in the wiring of a car of a grade to which the keyless entry device is not applied, since only two switching elements are added, the same wire harness can be shared. Therefore, there is no need to manufacture a plurality of types of wire harnesses, and production costs can be reduced. Furthermore, even if a keyless entry device and / or a device not equipped with an answer-back system are selected when a vehicle is purchased, these devices can be easily and inexpensively installed later.

Further, since the first switching element is constituted by a relay, it is possible to make the lamp blink without lowering the light amount of the lamp as compared with the case where a transistor is applied. Therefore, the situation can be reliably notified to the traveling vehicle, and safety can be ensured.
