This anti-theft device 20 has a structure hard to be removed from a vehicle 1, and if the anti-theft device 20 is tended to be removed or broken, an airbag device 11 and an alarm sound generating device 14 are actuated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle antitheft device for preventing vehicle theft.

[0002]

2. Description of the Related Art In recent years, various antitheft devices have been developed and sold by vehicle manufacturers in order to prevent theft of frequently occurring vehicles. For example, a sensor detects an intrusion into the vehicle to generate an alarm sound, or a special tool is used to detect the vibration of the vehicle and generate an alarm sound. Anti-theft device (Prior Art 1), a theft prevention device (Prior Art 2) that locks the steering wheel and the brake pedal by connecting them with a connecting rod during parking,
Anti-theft equipped with an electronic control system such as an immobilizer system that allows unlocking the door and starting the engine only when the information stored in the engine key (ignition key) matches the information stored in the engine control computer A device (prior art 3) is known.

On the other hand, Japanese Utility Model Publication No. 60-20448 and Japanese Utility Model Publication No. 1-
Japanese Patent No. 142022 discloses a vehicle anti-theft device (prior art 4) that includes a fixing mechanism portion that fixes the shift lever to the parking position and a locking portion that locks the fixing mechanism portion. Further, Japanese Utility Model Laid-Open No. 6-60563 and Japanese Patent Laid-Open No. 7-291096 disclose an anti-theft device (prior art 5) including an anti-theft switch between a battery and an ignition switch.

[0004]

In the prior art 1, it is difficult to adjust the sensitivity of the sensor, and when a heavy-duty vehicle passes by or reacts to sway or strong wind caused by an earthquake, the alarm sound due to malfunction causes noise. There is a risk. Prior art 2 is
The wearing was cumbersome and the crime prevention effect was not perfect. Conventional technology 3 is gradually introduced mainly in high-end cars, which is said to be the ultimate anti-theft technology, but the installation rate is still low, and even if this immobilizer system is installed in the vehicle, the protection is broken and it is actually stolen. Is being reported to have occurred. The prior art 4 has a high reliability and a simple structure because the shift lever is mechanically fixed, but there is a problem in that the vehicle is easily stolen if a thief destroys the device and removes it. The prior art 5 has a problem that if the place where the antitheft switch is installed is known to the thief, the antitheft switch is easily destroyed.

In the theft of a vehicle, it is necessary to take out the vehicle in a short time as in the case of theft of a general house by so-called picking. For this reason, a single anti-theft device cannot be expected to have a crime prevention effect, and a plurality of anti-theft devices can be installed so that it takes a long time to steal a vehicle, and the thief can be abandoned. It is considered to be an effective crime prevention measure.

Most current vehicles have important equipment such as batteries and engines concentratedly installed in the engine room, but the protection against unauthorized access to the engine room is insufficient. For this reason, if the thief succeeds in entering the driver's cab, the engine room can be easily opened, and damage to the devices in the engine room cannot be completely prevented. As a result, if the thief once releases the battery terminal that is the power source of the alarm sound generator and disconnects the wiring of the alarm sound generator,
Even if the battery terminal is connected again after that, there is a problem that the vehicle can be easily removed without operating the alarm sound generator.

An object of the present invention is to provide a vehicle antitheft device capable of improving the antitheft effect.
