DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle burglar alarm system for preventing vandalism or theft of a vehicle.

[0002]

2. Description of the Related Art Conventionally, there are various types of automobile burglar alarm systems.
There have been various proposals for making a theft report using a wireless telephone mounted on a car when an abnormal situation occurs.

For example, Japanese Patent Application Laid-Open No. 2-274842 discloses that after locking is completed, an abnormality monitoring state is established. When a signal from a door sensor or a movement sensor is received, a call connection of a car telephone is made and the telephone of the car owner is connected. A device that connects to and informs the user is shown.

Japanese Patent Application Laid-Open No. 3-266746 discloses that the theft monitoring means detects a theft such as prying a door lock. When the theft is detected, a horn is sounded and a headlight is turned on. A system is shown in which a blinking alarm is given to the surroundings by blinking, and an automatic call is made to a telephone number of a center set in advance in a car telephone to report the same.

Japanese Patent Application Laid-Open No. 4-36164 discloses that when a movement of a wireless telephone is detected without inputting a correct password, it is determined that the vehicle has been stolen, and the wireless communication device mounted on the vehicle has been determined. An apparatus is shown in which a telephone calls a telephone number registered in advance and notifies the occurrence of theft.

Japanese Unexamined Patent Publication No. 9-249095 discloses that voice recognition data input at the time of boarding is collated with voice recognition data registered in advance, and if correct data is not input within a predetermined time, the vehicle is rejected. A device is shown in which the vehicle telephone determines that the device has been used illegally, makes a line connection to the owner's telephone, and transmits the current position information of the vehicle measured by the vehicle position measuring device.

However, in the above-described apparatus disclosed in Japanese Patent Application Laid-Open No. Hei 2-274642, a theft notification process is immediately performed as an abnormal situation by a signal from a door sensor or a movement sensor. For this reason, it is unnecessarily erroneously detected that an abnormal situation has occurred, and the malfunction is likely to occur. Further, only the notification process is performed, and the stolen vehicle cannot be caused to perform an alarm operation to the surroundings.

In a system disclosed in Japanese Patent Application Laid-Open No. 3-266746, theft is detected immediately upon detection of opening of a door lock of a vehicle (ie, irrespective of an operation based on the will of the owner of the vehicle). Since the act is alerted to the surroundings (and then or simultaneously reports the theft), malfunctions are likely to occur similarly to the above, and the use of a security company system increases costs.

Further, in the device disclosed in Japanese Patent Application Laid-Open No. 4-36164, theft detection is performed by detecting the movement of the wireless telephone, so that the configuration for theft detection becomes complicated.
The cost increases, and only the notification process is performed, and the stolen vehicle cannot be alerted to the surrounding area.

[0010] Further, in the apparatus disclosed in Japanese Patent Application Laid-Open No. 9-249095, since the current position information of the vehicle is reported, the cost becomes high, and the stolen vehicle is caused to perform an alarm operation to the surrounding area. Can not.

The call is automatically transmitted to the telephone of the car owner.

In the configuration of the present invention, if the door is opened from the ON state of the theft notification function and a predetermined password is not input within a predetermined time from that point of time, it is considered that an abnormal situation such as a car theft is occurring. Upon making the determination, the radio telephone is automatically transmitted, the radio telephone receives a key operation signal from the telephone of the car owner responding thereto, and operates the abnormality notification means based on the output signal. That is, after performing the notification process to the owner of the vehicle, the stolen vehicle is caused to perform an alarm operation to the surroundings by operating the telephone of the vehicle owner based on the will of the owner. For this reason, it is possible to prevent an erroneous operation from being unnecessarily erroneously detected as the occurrence of an abnormal situation.

Moreover, the above-mentioned theft notification function can be installed and used only by the owner of the car without the intervention of a third party (such as a security company), and a low-cost device can be obtained. Further, if the door lock signal is not input within a predetermined time after the theft report function is set to the ON state by using the resources of the theft report function means as it is, the door is forgotten to be locked. Thus, the wireless telephone can notify the telephone of the car owner, and cost reduction can be achieved.

Further, the control unit inputs a command for setting the theft reporting function to the ON state from the input unit, and inputs a door lock signal from the signal input unit to turn on the theft reporting function. In the set state, the wireless telephone automatically receives a call in response to a call from the external telephone to the wireless telephone, and unlocks the door in response to a predetermined password input from the external telephone. It may be operated.

In the above configuration, the door can be unlocked by inputting a predetermined password from an external telephone, so that the key of the vehicle can be inexpensively utilized by utilizing the resources of the theft reporting function means. Can be easily avoided from the situation where the user locks the door and forgets to lock the door.
