[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for vehicle equipment in which a door control function and an anti-theft function can be commonly controlled by a remote control function which is retrofitted. The present invention relates to a remote control device for vehicle equipment, which can cancel the release with one touch.

[0002]

2. Description of the Related Art In recent vehicles, a door lock control device which can control locking / unlocking of all doors with a single touch or a door in a locked state is a proper means (for example, a key).
There is a tendency to provide an anti-theft device or the like that issues an alarm when opened when the device is not used, and there is also a device in which these devices can be remotely controlled from outside the vehicle using a remote control device.

In this case, since the door lock control device and the anti-theft device have a common input signal, they can be controlled by the same remote control device. That is,

(1) A door lock control device (general type) is provided with a key lock / unlock signal obtained from a switch in a key cylinder of a driver's seat or a passenger's seat door or a similar signal obtained from a manual switch inside a door. Is detected, and the locking / unlocking of all doors is controlled by a drive source such as a solenoid or a motor according to the signal.

(2) The anti-theft device (general type)
The system is set by a key lock or keyless lock by a door key, and the system is reset by a key unlock by a door key.

(3) The remote control device detects the locked / unlocked state of the door, and outputs a lock signal or an unlock signal for reversing the locked / unlocked state of the door when receiving a radio wave from the transmitter. I do.

Therefore, when these are combined, the following complex system is constructed.

(4) The remote control type door lock control device combines the functions of (1) and (3) so that the lock / unlock of the door can be remotely controlled from outside the vehicle.

(5) A system called a door lock control integrated type anti-theft device realizes both functions of (1) locking / unlocking the door and (2) anti-theft by one computer, thereby preventing theft. The system is set / reset in the same manner as in (2).

(6) In a system called a remote control type door lock control integrated anti-theft device, a remote control device of (3) is added in advance to the equipment of (5),
Set / reset anti-theft system and lock door /
It is designed so that unlocking can be controlled by the same remote control.

[0011]

When a remote control device of (3) is retrofitted to a vehicle equipped with a door lock control device of (1) and an anti-theft device of (2), the following will occur. Cause problems.

The anti-theft device issues an alarm when the system is set and the door is unlocked without using the key (when the key is used to unlock the door, the system is reset and the alarm is issued). Does not appear). To stop this alarm you need to reset the system,
For that purpose, a key unlock signal is required.

However, when the transmitter is operated for remote control, the first output from the remote control device is the reverse of the lock / unlock state of the door at that time (in this case, the unlock state). Alarm (in this case, a lock signal), this operation does not stop the alarm.

However, when the transmitter is operated next time, a key unlock signal for changing the locked state to the unlocked state is output, whereby the system is reset and the alarm is stopped.

The remote control type door lock control integrated anti-theft device (b) described above is configured so that the remote control device can recognize the state of the anti-theft device, that is, whether or not an alarm is being issued. Such a problem does not occur.

However, since the retrofitting remote control device does not have a configuration for externally detecting whether or not the anti-theft device is alerting, the alarm does not stop unless the transmitter is operated twice as described above. There is.

An object of the present invention is to make it possible to stop the theft alarm with a single operation of the transmitter, even if the remote control device is retrofitted.

A further object of the present invention is to make it possible for the anti-theft device having the re-alarm mode to cancel the re-alarm state with a single operation of the transmitter.

[0019]

SUMMARY OF THE INVENTION The present invention provides a key lock /
A door lock control device that controls lock / unlock of a door in response to a key unlock signal, and an anti-theft device that issues an alarm when the door is detected to be open between set and reset. A remote control device of the vehicle equipment shared with the, detecting whether the anti-theft device is in alarm or re-warning from the state of the external circuit components controlled by the anti-theft device, during the alarm or If the control signal from the transmitter is received, the lock signal or the unlock signal for reversing the lock / unlock state of the door is output when the control signal from the transmitter is not being watched. When receiving a control signal from the door, a reset signal is output irrespective of the locked / unlocked state of the door.

[0020]

According to the above arrangement, in a vehicle facility in which the door control function and the anti-theft function can be commonly controlled by a retrofitting remote control function, the theft alarm can be stopped by one remote control operation. , You can cancel the re-alert state.

[0021]

FIG. 1 is a block diagram showing an embodiment of the present invention.
Reference numeral 0 denotes a door lock control (hereinafter abbreviated as door control) device, 20 denotes an anti-theft device, and 30 denotes a remote control (hereinafter abbreviated as remote control) device.

The door control device 10 detects a key lock / key unlock state from a key lock / key unlock switch 11 in a driver seat (D seat) and a passenger seat (P seat).
Further, the open / closed state of the door is detected from the courtesy switch 12 in the D and P seats. When the key lock signal is detected, the door lock motors 13 and 14 of the D and P seats are rotated to lock the doors of the D and P seats. Is unlocked. The motors 13 and 14 have a built-in switch for turning on / off according to lock / unlock, and the door controller 10 can confirm the lock / unlock state of the door by the switch.

When the anti-theft device 20 is set (S) by a key lock signal, it becomes alert, and when it detects that it has been unlocked without using a key during alerting, the monitor LED 2
4 is turned on and the horn 21 is sounded to give an alarm. When the device 20 is reset (R) by the key unlock signal, the warning state is released, and the door open detection and the driving of the horn 21 are stopped.

Since the anti-theft device 20 uses the same input as the door control device 10, when the remote device 30 is retrofitted to the door control device 10, the anti-theft device 20 is also set / reset by the key lock / key unlock output of the remote control device 30. Are controlled simultaneously.

The general remote controller 30 alternately outputs a lock signal and an unlock signal each time a radio wave from the portable transmitter 31 is received by the receiving antenna 32. The same applies to the remote control device 30 of the present example while the anti-theft device 20 is not in alarm. However, during a warning, only the key unlock signal (reset signal) is output.

In this embodiment, the state of the starter relay 22 is detected in order to detect whether or not the anti-theft device 20 is in the alarm state with the remote control device 30 attached thereto. This starter relay 2
Reference numeral 2 is connected in series with the starter switch 23, and is turned off during a burglar alarm to disable the starter switch 23 (the engine does not start because the starter motor does not rotate).

FIG. 2 is a detailed view of this part. The anti-theft device 20 has a relay L1 and its driver transistor TR1 at the output stage, and sets the contact r of the relay L1 to b when there is no alarm.
And one end of the starter relay 22 is grounded. Therefore, when the starter switch 23 (see FIG. 1) connected in series with the starter relay 22 is turned on, the starter motor is energized.

However, during the alarm, the contact r of the relay L1 is set to a.
Side, one end of the starter relay 22 is opened, and even if the starter switch 23 is turned on, power is not supplied to the starter motor.

The remote controller 30 is connected to the starter relay 2
It is detected whether one end of 2 is in an open state or a ground state, and it is determined whether or not an alarm is being issued. Diode D1 and pull-up resistor R
Reference numeral 1 denotes an input circuit for this, and the potential at the connection point A between D1 and R1 is input to the microcomputer.

FIG. 3 is a flowchart of remote control processing by the microcomputer. This process starts when the battery is connected, and first, the initialization in step S1 is performed. Next, in step S2, a radio wave from the transmitter 31 is waited, and when it is received, the state of the courtesy switch 12 is determined in step S3. Here, if it is determined that the courtesy is closed (door closed), the flag is cleared to 0 in step S4, and if it is determined that the courtesy is open (door open), the flag is set to 1 in step S5.

Next, in steps S6 and S7, it is determined whether the seats D and P are locked or unlocked. If both are locked, a key unlock signal is output in step S8 and step S1 is executed.
Return to This is a case where all doors are unlocked and all doors are unlocked.

On the other hand, if it is determined in any of steps S6 and S7 that the lock is unlocked, a preparation is made in step S11 to output a key lock signal. However, this is 2
There are two exceptions.

One is when it is determined in step S10 that flag = 1 (door open). This is the logic of the door control that it is inconvenient to lock when not all doors are closed. At this time, the process returns to step S1 without issuing a key unlock signal as well as a key lock signal.

The other one is to determine a starter input (A in FIG. 2) in step S9, and when this is Hi, proceed to step S8 to perform a process during a warning for outputting a key unlock signal (reset signal). is there. By this processing, the key unlock signal is output even in the door unlock state,
The alarm can be stopped by resetting the anti-theft device 20 by one operation of the transmitter.

When it is determined in step S10 that the flag is "0", a key lock signal is output in step S11, so that the operation is performed according to the locked / unlocked state of the door as in the case of a normal remote controller.

FIG. 4 is a time chart showing the operation of the present invention. First, when the transmission radio wave is received at the timing A, since the courtesy is closed, lock control is performed, and at the same time, the anti-theft device is set. As a result, the system enters the alert state, and is unlocked without the key at the timing of B, and when the courtesy is opened, an alarm is issued and the starter input is set to Hi at the same time. This alarm is issued for a certain period of time (for example, 60
Second), but if it is stopped before that, a transmission radio wave is emitted at the timing of C. This is the method described in the above embodiment.

By the way, depending on the system, if the courtesy is closed at the timing of D after the alarm for a certain period of time is completed, the alarm is re-alert in the unlocked state. In this re-warning state, an alarm is issued again when the courtesy is opened as in E. This re-alert state can also be reset by an unlock signal, but since it is already in the unlock state, a lock signal is output when the transmission radio wave F is received in the conventional method. However, in the present invention, since the starter input remains Hi at the first alarm, the unlock signal is output from step S9 to step S8 in FIG. 2 also in this case. Therefore, the re-alert state can be canceled with one touch.

[0038]

As described above, according to the present invention, in a vehicle facility in which the door control function and the anti-theft function can be commonly controlled by a retrofitting remote control function, theft is achieved by one remote control operation. The alarm can be stopped and the re-alert state can be released.
