1. A security apparatus for automatically locking a door, comprising:
- a door lock switch for generating a door-unlocked signal when the door changes from a locked state to an unlocked state;
a sensor for detecting movement within a monitored area adjacent the door and for generating one of a first detection signal in response to detected movement within the monitored area, and a second detection signal in the absence of detected movement within the monitored area;
a security controller for generating a door lock command signal when the sensor continuously generates the second detection signal for a predetermined time period following the generation of the door-unlocked signal by the door lock switch; and
door lock/unlock means for locking the door in response to the door lock command signal.

Abstract
A security apparatus which automatically locks a door even though a door locking operation is not performed. A security controller drives a door lock device to automatically lock a door if the door is not locked even when a lapse of time exceeds a set time and if a detection signal is not output from a radar sensor after the door has been unlocked. With this arrangement, even when a driver unlocks the door intending to get in the vehicle, but decides not to do so, and also when he/she leaves the vehicle without performing an arming operation, the door can be automatically locked.

9. A security system comprising:
-
a remote control unit for transmitting a remote control signal; and a security apparatus comprising; a receiving circuit for receiving the remote control signal via an antenna; a door lock switch for generating a door-unlocked signal when the door changes from a locked state to an unlocked state; a sensor for detecting movement within a monitored area adjacent the door and for generating one of a first detection signal in response to detected movement within the monitored area, and a second detection signal in the absence of detected movement within the monitored area; a security controller for receiving the remote control signal from the receiving circuit, for generating one of a door lock command signal and a door unlock command signal in response to the received remote control signal, and for generating a door lock command signal when the sensor continuously generates the second detection signal for a predetermined time period following the generation of the door-unlocked signal by the door lock switch; and door lock/unlock means for locking the door in response to the door lock command signal and for unlocking the door in response to the door unlock command signal. - View Dependent Claims (10, 11, 12, 13, 14)

15. A security system comprising:
-
a remote control unit for transmitting a remote control signal including an ID code and an arming/disarming code; and a security apparatus comprising; a receiving circuit for receiving the remote control signal via an antenna; a door lock switch for generating a door-unlocked signal when the door changes from a locked state to an unlocked state; a sensor for detecting movement within a monitored area adjacent the door and for generating one of a first detection signal in response to detected movement within the monitored area, and a second detection signal in the absence of detected movement within the monitored area; a security controller for receiving the remote control signal from the receiving circuit, for comparing the ID code of the remote control signal with a preset ID code, and when the ID code of the remote control signal coincides with the preset ID code, for generating one of a door lock command signal and a door unlock command signal in response to the arming/disarming code, and for generating a door lock command signal when the sensor continuously generates the second detection signal for a predetermined time period following the generation of the door-unlocked signal by the door lock switch; and door lock/unlock means for locking the door in response to the door lock command signal and for unlocking the door in response to the door unlock command signal. - View Dependent Claims (16, 17, 18, 19, 20)
