Description

[0001]
BACKGROUND OF THE INVENTION
The present invention, for example, a mobile theft that once limits the travel when detecting the theft of a mobile body such as an automobile or a motorcycle, and that the restriction can be easily released when the stolen mobile body is recovered. It relates to countermeasure devices.
[0002]
[Prior art]
Conventionally, for example, as a mobile theft countermeasure device that detects theft of a mobile body (hereinafter, described as an example of a vehicle) and imposes restrictions on travel to make the vehicle difficult to travel, JP-A-8-77471 is disclosed. There is a gazette. FIG. 3 is a block diagram showing the configuration of this mobile theft countermeasure device. Reference numeral 101 denotes a vehicle position where a GPS signal received by the GPS receiving antenna 106 is input to detect a vehicle position (hereinafter referred to as a vehicle position). Detection means 102 is a theft determination area information storage means for storing the theft determination area information for determining an intruding vehicle as a stolen vehicle, and 103 is the vehicle position information from the vehicle position detection means 101 and the area designation means 102. A theft detection unit 104 detects a theft based on the theft determination area information, and a brake control unit 104 activates the braking unit 105 based on a theft detection signal from the theft detection unit 103. As the braking means 105, for example, an engine, a transmission, or the like is controlled to make the vehicle unmovable or difficult to make it impossible to move the vehicle or to issue an alarm. Let me know.
[0003]
Next, the operation will be described.
FIG. 4 is a flowchart for explaining the operation. Using information input means (not shown) such as a remote controller or a keyboard in advance, the theft determination area information such as latitude and longitude is stored in the theft determination area information storage means 102 in advance (step ST101).
[0004]
The own vehicle position detection means 101 such as a global positioning system (GPS) detects the latest own vehicle position at a constant cycle (step ST102). The vehicle position detection means 101 may use a method of detecting the vehicle position information from wireless communication such as narrow area wireless communication (DSRC) or wireless LAN.
[0005]
The theft detection means 103 compares the theft determination area information stored in the theft determination area information storage means 102 with the latest vehicle position information detected by the own vehicle position detection means 101, and the vehicle position is within the theft determination area. (YES in step ST103), if it is YES, it is detected that the vehicle has been stolen, and this detection signal is supplied to the braking control means 104. Receiving the supply of the detection signal, the braking control means 104 operates the control means 105 to control the transmission, the engine, etc. to make the vehicle difficult to travel (step ST104). Here, the situation where it is difficult to travel is, for example, that the vehicle can travel such that the transmission is fixed at the first speed, the fuel injection fee is fixed in a small amount, but the normal traveling cannot be performed. In addition, by setting the above-described theft determination area as an area other than Japan, the stolen vehicle can be made unusable when it is exported overseas.
[0006]
[Problems to be solved by the invention]
Since the conventional mobile theft countermeasure device is configured as described above, it is determined that the vehicle has been stolen when it comes out of a pre-designated area, and the vehicle is driven with braking means such as fixing the transmission to the first speed. Theft is prevented by making it difficult. However, once the vehicle is difficult to travel, even if the stolen car is recovered by the owner, the owner has no means to release the braking function. There is a problem that the vehicle cannot be returned to a normal running state unless it is specially released by a person.
[0007]
The present invention has been made to solve the above-described problems. When it is determined that the vehicle has been stolen, the travel restriction is performed by operating the braking means, and then when the stolen vehicle is recovered, the travel restriction is performed. The purpose is to obtain a mobile anti-theft device that allows the owner of the vehicle to easily release the travel restriction and return it to a normal running state again without any special work by a third party such as a dealer. And

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, an embodiment of the present invention will be described.
Embodiment 1 FIG.
FIG. 1 is a block diagram showing the configuration of a mobile theft countermeasure device according to Embodiment 1 of the present invention, where 1 is on-vehicle control means, 2 is restriction release area information input means, 3 is restriction release area display means, and 4 is It is a braking means as a travel restriction means.
[0014]
The in-vehicle control means 1 receives the restriction release area information (area information for releasing the travel restriction imposed on the vehicle when the vehicle exists in a certain area) input from the restriction release area information input means 2. The restriction release area information storage means 11 for storing and supplying the restriction release area information to the restriction release area display means 3 and the theft determination area information storage for storing preset area information for determining the approaching vehicle as a stolen vehicle Means 12, vehicle position detection means 14 for detecting the vehicle position based on a received signal from the GPS receiving antenna 13, information read from the theft determination area information storage means 12, and information read from the vehicle position detection means 14 Based on the information read from the theft detection means 15 for detecting theft based on the information thus obtained, the restriction release area information storage means 11 and the information read from the vehicle position detection means 14. When the detection means (releasable detection means) 16 for detecting that the vehicle is in the restriction release area and the theft detection signal from the theft detection means 15, the fuel injection amount is fixed at a small amount. When a brake release signal is received, a brake control means 18 having a signal determination means (running restriction means, restriction release means) 17 for controlling the braking means 4 so as to release the fixing of the fuel injection amount to a small amount is provided. I have it.
[0015]
Next, the operation will be described.
FIG. 2 is a flowchart for explaining the operation of the mobile theft countermeasure device according to the present invention. The restriction release area information is stored in the restriction release area information storage means 11 in advance using the restriction release area information input means 2 such as a remote control or a keyboard and the restriction release area information display means 3 such as a monitor display (step ST1). This restriction release area information may be position data such as latitude and longitude, or data such as an address obtained from a database stored in a storage device (not shown) such as a separately connected CD-ROM.
[0016]
The vehicle position detection means 14 such as a global positioning system (GPS) detects the latest vehicle position at a constant cycle (step ST2). This vehicle position detection means 14 is a method for detecting vehicle position information by calculation processing of sensor output from a wireless communication such as narrow area wireless communication (DSRC) or wireless LAN, or a direction sensor, a mileage sensor, etc. It may be used.
[0017]
The theft detection means 15 compares the theft determination area information stored in the theft determination area information storage means 12 with the latest vehicle position information output from the own vehicle position detection means 14, and the vehicle position is within the theft determination area. Is present (step ST3), and if it is YES, it is detected that the vehicle has been stolen. Receiving the supply of the detection signal, the braking control means 9 operates the braking means 4 to make it difficult for the vehicle to travel the transmission, engine, etc. (step ST4). Here, the difficult traveling condition means that the transmission is fixed at the first speed, the fuel injection fee is fixed at a small amount, and the like, but the normal traveling is impossible.
[0018]
On the other hand, after the stolen vehicle is found and collected, the stolen vehicle is moved to the restriction release area stored in the restriction release area information storage means 11 and the vehicle position detection means 14 performs the vehicle position detection process ( Step ST5). Next, the detection means 16 compares the restriction release area information read from the restriction release area information storage means 11 with the latest vehicle position information obtained from the vehicle position detection means 14, and the recovered stolen vehicle is detected. It is determined whether or not it exists in the brake release area (step ST6). If YES, a restriction release signal is output to the brake control means 18, and the braking restriction imposed on the brake control means 18 by the theft detection means 15 is determined. Is canceled to bring the vehicle into a state in which it can normally travel (step ST7).
[0019]
Then, when the determination result in step ST3 is NO, the process returns to step ST2 to repeat the above operation. If the determination result in step ST6 is NO, the process returns to step ST5 and the latest vehicle position detection process is performed.
[0020]
As described above, in the illustrated example, as a travel restriction release means that can be performed by the owner, the vehicle receives the braking release signal from the detection means that detects the release using the vehicle position information and the preset restriction release area information. The braking restriction release processing for releasing the travel restriction imposed on the vehicle and making the vehicle in a state in which the vehicle can normally run has been described. However, as described above, as the travel restriction release means that allows the owner to release the travel restriction as described above, for example, a button unit owned only by the owner is operated to input a travel restriction release signal to the signal determination means 17. Then, a password known only to the owner is input from an input means such as a keyboard. Alternatively, the travel restriction may be canceled by inputting an owner-specific ID authentication signal such as a fingerprint or a voiceprint. In other words, the travel restriction releasing means is configured to release the travel restriction based on a certain command.
[0021]
As described above, according to the first embodiment, by collecting the stolen vehicle, the owner can easily release the difficult traveling situation imposed when the theft is detected.
[0024]
【The invention's effect】
According to the present invention, the travel restriction release means is configured to release the travel restriction based on the collected stolen mobile body entering the restriction release area, and therefore only collects the stolen vehicle in the restriction release area. In this way, the vehicle can be returned to the normal running state again.
