    The present invention provides a door lock detection apparatus of a vehicle, which prevents theft or the like caused by the door of the vehicle not being locked by removing the key from being inserted into the key holder of the door when any of the doors are not locked. The present invention relates to a warning device when the automatic door lock of a vehicle is not activated, and includes a first to fourth detection sensor (10-13) in each door of the vehicle, wherein the detection sensor (10-13) is used. It is provided with an AND gate 20 to detect when any one door is unlocked and output a signal of a predetermined level, and operate to lock the door when a signal of a predetermined level is output from the AND gate 20. The first to fourth door actuators 30-33 and the warning sound generating unit 50 for generating a warning sound are provided to prevent an accident such as a vehicle theft in advance.

    DETECTION DEVICE OF DOOR LOCKING FOR A CAR
    The present invention relates to a door lock detection device for a vehicle, and more particularly, to a door lock device for a vehicle, wherein the door of the vehicle is prevented from being pulled out while the key is inserted into the key holder of the door in a state in which any one door is not locked. The present invention relates to a door lock detection device for a vehicle that prevents vehicle theft caused by being locked out in advance.
    In addition, when the door is unlocked completely by the driver's recognition, the key is removed from the key holder, and a warning sound sounds to alert the driver.
    Recently, when the driver's door is locked, the passenger seat and the rear seat door are locked at the same time, thereby adding convenience to the vehicle. Similarly, when the door is opened, all the remaining doors are opened by only opening the driver's door. Here, the actuator mounted on each door is operated to turn on / off the door when the key is turned on or off.
    However, in the door lock device of the conventional vehicle, the actuator of each door is operated when the door is locked or opened, and it is difficult for the driver to know when the actuator of any one of the actuators of each door is not operated. There is a problem that the door is completely closed, and the product is easily susceptible to accidents such as loss of goods and vehicle theft.
    Therefore, in order to solve the above-mentioned problems, the present invention enables the driver to prevent the key inserted in the driver's seat door key holder from being pulled out when the actuator is not operated even when one of the plurality of actuators for the door is not locked. Detect the door lock of a vehicle so that the actuator can be notified that there is an unlocked door, and when the actuators are all activated, the key is released and a predetermined warning sound is issued to indicate that the doors are all locked. To provide a device.
    1 is a block diagram of a door lock detection apparatus for a vehicle according to the present invention.

    The present invention for achieving the above object is a door lock device of a vehicle, a plurality of sensors attached to each door of the vehicle to detect the lock / unlock, and any one door of the door by the sensor to unlock And gates for detecting a predetermined level and outputting a signal of a predetermined level, a plurality of door actuators that operate to lock the door when a predetermined level signal is output from the AND gate, and a signal of a predetermined level from the AND gate. It is provided with a warning sound generating unit for generating a warning sound through the speaker when the output.
    Hereinafter, a preferred embodiment of a door lock detection apparatus for a vehicle according to the present invention will be described in more detail with reference to the accompanying drawings.
    1 is a schematic configuration diagram of a warning device when the door lock of the vehicle is not operating according to the present invention, the first to fourth detection sensors (10-13) attached to each door of the vehicle to detect the lock / unlock, and the And gate 20 which detects when any of the doors are unlocked by the first to fourth detection sensors 10-13 and outputs a signal of a predetermined level, and predetermined from the end gate 20. First to fourth door actuators 30 to 33 which operate to lock the door when a level signal is output, and a beep sound through the speaker 40 when a predetermined level signal is output from the AND gate 20. It consists of a warning sound generating unit 50 for generating a.
    Referring to the operation principle of the door lock detection apparatus of the vehicle configured as described above are as follows.
    That is, the vehicle is stopped and the occupant gets off and locks the door by inserting a key into the key holder of the door and rotating the door. At this time, the door lock is locked by the first to fourth detection sensors 10-13 attached to each door. It will detect if there is a door that is not. If all the doors are locked, a low level is output from the AND gate 20 so that no alarm sounds, and at this time, the key can be easily removed from the key holder. However, if any one of the doors is not locked, the corresponding sensor detects this, and a high level signal is output from the AND gate 20. Thus, at this time, the key does not come out of the key holder so that the driver can know that one of the actuators is not operated.
    When the key does not come out from the key holder of the door as described above, the driver can turn the key again to lock the door. Accordingly, when a low level signal is output from the end gate 20, the first to fourth door actuators (30-33) is operated and all the doors are locked. In this state, all the doors are locked, while the key is released from the key holder and a warning sound is generated to the speaker 40 through the warning sound generating unit 50 to alert the driver. It can be called up.
    As described above, according to the warning device when the automatic door lock of the vehicle of the present invention is not in operation, the driver does not remove the key when the door is inserted into the key holder of the door when the door of the vehicle is not locked. It is easy to recognize that it is not completely locked, and thus the door can be locked again, thereby preventing the vehicle from being stolen due to the door of the vehicle being locked. In addition, when the doors are fully locked, the key is released and at the same time there is an effect that can alert the driver by the alarm sound.
