BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle antitheft device, and more particularly to a vehicle antitheft device suitable for preventing the device from being accidentally disarmed during an arming operation.

[0002]

2. Description of the Related Art As a conventional vehicle theft prevention device with a remote control reception function, the arm / disarm setting of the device is controlled by a remote control, and this remote control is a key holder type so that it can be attached to a car key. However, the owner of the vehicle set the arming state with the remote control every time the vehicle owner left the vehicle.

[0003]

However, in most of the conventional vehicle theft prevention devices described above, the remote controller is attached to the key holder of the vehicle. Therefore, when the user leaves the vehicle, the remote controller is set to the arming state and then the remote controller is set. Also, the key is often put in a pocket or the like, and at this time, the remote controller may be mistakenly pushed when the vehicle cannot be seen, and there is a drawback that the device is not noticed even when the device is disarmed.

The present invention has been made in view of the above-mentioned points, and the purpose thereof is to eliminate the conventional drawbacks and prevent the device during arming operation from being accidentally disarmed. It is in the area of providing a protection device.

FIG. 1 is a functional block diagram of the present invention. A vehicle antitheft device of the present invention has a sensor input means for inputting a detection signal from a sensor portion and a vehicle door lock or lock. Door lock / unlock output means for unlocking, horn output means for detecting an abnormal signal from the sensor section and outputting an alarm signal, and remote control receiving means for receiving an arming / disarming setting signal from the outside by a remote control A vehicle anti-theft device comprising a verifying means for confirming all alarm operations and a panel key input means for inputting a function setting to a microcomputer, the vehicle anti-theft device disarm command during an arming operation. A disarm command confirmation means for confirming that the device has received
It is configured to enter the disarm state when the disarm setting code is input once.

[0006]

The operation of this invention will be described with reference to FIG.

According to this invention, the sensor input means for inputting the detection signal from the sensor portion, the door lock / unlock output means for locking or unlocking the vehicle door, and the abnormal signal detected by the sensor portion And a horn output means for outputting an alarm signal, a remote control receiving means for receiving an arming / disarming setting signal from the outside by a remote controller, a verifying means for confirming all alarm operations, and a function setting input to a microcomputer. In the vehicle anti-theft device including the panel key input means, the remote control receiving means receives the arming command and the device is disarmed only after receiving N disarm commands during the arming operation. Arm command confirmation means is provided so that the device can be operated N times within a fixed time by remote control operation. Can be operated so that the disarmed setting state when entering beam configuration code.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a vehicle antitheft device according to the present invention will be described with reference to FIGS.

In the figure, 1 is a remote control receiving device for receiving an arm / disarm command by remote control operation, 2 is a microcomputer for controlling this device, 3 is an alarm device for performing an alarm operation when the device detects an abnormality, 4 Is a sensor for detecting a vehicle abnormality, and 5 is a panel key for inputting operation settings of the apparatus.

Further, the microcomputer 2 is composed of a central processing unit for processing data, a ROM for storing a program to be executed, a RAM for storing data and an input / output port, and the remote control receiving device 1, the sensor. 4 and the panel key 5 are connected to the input port of the microcomputer 2, and the alarm device 3 is connected to the output port of the microcomputer 2.

The vehicle anti-theft device of the present invention receives the disarm command N times within a fixed time by the remote control operation during the arming operation by the arm command received by the remote control receiver 1 so that the device is disarmed for the first time. It comes to be in a state.

Next, the operation of this apparatus will be described with reference to the flowchart of FIG.

The example of this flow chart shows a case in which the disarm setting is made by two disarm commands. When this device starts operation, it is checked whether the device is in the arming operation (step S1).

If the device is in the arming operation in step S1, it is checked whether or not a disarm command is input by remote control operation (step S).
2).

If the remote control receiver 1 receives the disarm setting code, the time in the microcomputer 2
Check the operation of r, and if the Timer is operating, it means that the disarm setting code has already been received and the second disarm setting code has been received, so proceed to the next step, and if If Timer is not running
Set Timer for a fixed time (N seconds) (step S3, step S4).

If the Timer is operating in step S3, the flow is disarmed and set (step S5).

Next, it is checked whether or not Timer has passed a certain time (N seconds), and if N seconds have passed, the Timer operation is stopped (step S7).

If the timer has not passed N seconds in step S6, the timer is not stopped and the flow ends.

In this example, when the disarm command is received twice during the N seconds, the disarm setting state is set. However, the disarm command is issued twice or more times N times within a fixed time. It is also possible to provide a counter for counting the number of disarm commands in order to enter the disarm setting state, and to check the count number within a fixed time to bring the disarm setting state.

Further, until the disarm setting state is reached, if the verify operation (blinking of the parking light or ringing of the siren) is performed each time a disarm command is detected, remote control operation can be accepted. You can check.

As described above, the vehicle anti-theft device according to the present invention has the sensor input means for inputting the detection signal from the sensor portion, the door lock / unlock output means for locking or unlocking the vehicle door, and the sensor. Horn output means for detecting an abnormal signal from the section and outputting an alarm signal, a remote control receiving means for receiving an arming / disarming setting signal from the outside by a remote control, a verifying means for confirming all alarm operations, and a micro. In a vehicle anti-theft device configured with a panel key input means for inputting a function setting to a computer, disarm command confirmation means for confirming that the vehicle anti-theft device has received a disarm command during an arming operation, When the device inputs the disarm setting code N times within a certain time, Are those that you have configured so that.

[0022]

Since the vehicle antitheft apparatus according to the present invention is constructed as described above, it has the following effects.

There is an effect that it is possible to prevent the vehicle user from unintentionally operating the remote control to disarm the vehicle after the arming is set when the vehicle is away from the vehicle.

Moreover, it has excellent features such that the structure of the apparatus itself is not changed and the apparatus can be easily implemented.
