Abstract

PURPOSE:To discriminate an opening part in a way to divide it into a door and a trunk/hood by setting a burglar preventing function when a door, a trunk, and a hood are all closed during remote lock control and not setting the function when even a part is opened and announcing after a difference is discriminated by means of a horn and a lamp drive mode. CONSTITUTION:Switch signals from a switch 3 to represent ON/OFF of an accessory source ACC, a door courtesy switch 4 to show opening/closing of a door, a trunk courtesy switch 5 to show opening/closing of a truck, and a hood courtesy switch 6 are inputted to a microcomputer 1. When after a radio wave from a transmitter 7 is received, it is decided that all doors are closed, all the doors are locked. When the trunk and a hood are both closed, a horn is sounded one time and a parking lamp is lighted ON one time to set a burglar preventing function. When even the one of the trunk and the hood is opened, the horn is sounded three times and the parking lamp is lighted ON three times to set a burglar preventing function.

Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an anti-theft device for a vehicle that can be set/reset by remote control, and more particularly to an anti-theft device for a vehicle that notifies completion of setting/resetting using a horn and a lamp.

0002

[Prior Art] If the doors of a parked vehicle are unlocked without using a key, the vehicle itself or vehicle equipment may be stolen. To prevent this, the horn is blown. Anti-theft devices for vehicles have been put into practical use that take protective measures such as flashing the headlights to issue a theft alarm or cutting off the power supply system so that the engine cannot be started.

This type of anti-theft device is set when the vehicle is parked and the doors, trunk, and hood are all closed and the doors are locked. In general, there are two types of door locks: key locks that use a key and keyless locks that do not use a key, but recently remote control methods are also increasing. This is a remote control transmitter that locks/locks every time you press the transmit button.
This is a combination of a lock control mechanism that reverses unlocking and a remote control device.

[0004] Since this remote control function is often operated by operating the transmitter from a location away from the vehicle, a horn or lamp may be used to notify whether or not the anti-theft function has been set/reset as desired. .

[0005]

[Problems to be Solved by the Invention] The vehicle anti-theft device having the above-mentioned remote control function can be used to control doors, trunks,
You cannot set the hood if any part of it is open. In this case, the user needs to close the open part and then operate the button on the transmitter again.

[0006] However, if the user
It takes time to find out which part of the hood is not closed, and it is especially difficult to find parts of the hood that are slightly open when unlocked.

[0007] Moreover, even if you push each part with your hand to close it, it is difficult to determine whether that part is in the closed state where it can be set.
This is inconvenient because it cannot be determined unless the send button is operated again afterwards.

[0008] According to the present invention, it is possible to distinguish between the open parts of the door and the trunk/hood, and when the open parts are brought into the closed state, the set state is set without the need to operate the transmission button again. The purpose is to make it possible to immediately determine this from the operation of the horn and lamp.

[0009]

[Means for Solving the Problems] The present invention provides a door for a vehicle;
A means for individually detecting the opening and closing of the trunk and the hood, a means for remotely controlling the locking/unlocking of the door, and a means for preventing theft if the door, the trunk and the hood are all closed when the remote lock is controlled. means for setting the function and driving the horn and lamp of the vehicle in a first manner; and resetting the anti-theft function upon unlocking control of the remote and driving the horn and lamp in a second manner. means for driving the horn and lamp in a third manner when the door is closed but the trunk or hood is open during lock control of the remote; The vehicle is characterized by comprising means for setting the anti-theft function and driving the horn and lamp in the first mode when the trunk and the hood are all closed after being driven in the first mode. It is something.

0010

[Operation] The vehicle anti-theft device of the present invention is set if the doors, trunk, and hood are all closed during remote lock control, but is not set if any part of them is open. In the present invention, this difference is distinguished by the drive mode of the horn and lamp. In particular, to easily determine whether the cause of a set failure is a door opening or a trunk/hood opening.

[0011]Furthermore, a setting failure caused by opening the trunk/hood is automatically corrected when the trunk/hood is closed.
Moreover, this can be immediately determined from the driving manner of the horn and lamp. Therefore, the set state can be set without operating the transmission button again.

0012

[Embodiment] Fig. 1 is a block diagram showing an example of the anti-theft device for a vehicle according to the present invention. 1 is a microcomputer (hereinafter referred to as microcomputer) having an anti-theft function, a door lock/unlock control function, a remote control function, etc. (abbreviated).

This microcomputer 1 operates with a backup power supply +B directly connected to a battery 2, and an accessory power supply ACC.
Each switch signal is input: a switch 3 indicating on/off of the door, a door courtesy switch 4 indicating opening/closing of the door, a trunk courtesy switch 5 indicating opening/closing of the trunk, and a hood courtesy switch 6 indicating opening/closing of the hood. .

The remote control device is configured so that a reception circuit 9 receives a radio wave with an identification code transmitted when a transmission button 8 of the transmitter 7 is pressed, and inputs the detection signal to the microcomputer 1.

The door lock/unlock control device is configured to drive the door control relay 10 to the lock side or unlock side using the output L/U of the microcomputer 1.

The anti-theft device is configured such that a microcomputer 10 monitors input conditions and turns on a horn relay 11 and a parking lamp relay 12 when vehicle theft is detected. 13 is a horn driven by the relay 11, and 14 is a parking lamp driven by the relay 12.

The anti-theft device described above also uses the horn 13 and lamp 14 when the transmission button 8 is operated. FIG. 2 is a flowchart of the microcomputer 1 that performs this process.

The first step S1 in FIG. 2 is an initialization process for initializing each part, in which the anti-theft mode identification flag is set to 1. This flag is reset to 0,
1 indicates a set, and 2 indicates a set failure mode. however,
This set failure is caused by opening the trunk/hood, and the failure caused by opening the door is handled as part of the reset (=0) (N in step S5, which will be described later).

In the next step S2, it is determined whether the flag=2, and if N (no), that is, the flag=0 or 1, step S2 is performed.
3 to wait for radio waves from transmitter 7. If a radio wave is received here, it is determined in step S4 whether the flag = 0 or not, and if Y (yes), that is, the flag = 0 (reset), it is determined in step S5 whether the door courtesy is closed. If it is determined that the door courtesy is closed, that is, all doors are closed, a lock output is output in step S6 to lock all doors.

Next, in step S7, it is determined whether the trunk and hood are closed, and if both are closed, steps S8 to S11 are executed. In step S8, the horn is blown once, and in the subsequent step S9, the parking lamp is turned on once. Then, in step S10, the anti-theft function is set,
In step S11, the flag is set to 1 and the process returns to step S2. Through the flow of steps S2 to S11 described above, door locking and theft prevention setting can be automatically performed only by remote control.

On the other hand, if it is determined in step S7 that either the trunk or the hood is open, steps S12 to
Execute S14. In step S12, the horn is blown three times, and in the following step S13, the parking lamp is turned on three times. Then, in step S14, the flag is set to 2 (defective setting) and the process returns to step S2. This process is when the door is automatically locked, but the anti-theft set is not installed.

In this case, since flag=2 is determined in step S2, the process waits for both the trunk and the hood to be closed in step S15. This is step S12, S1
This is because the user who received the notification in step 3 manually closes the trunk and the hood, and as a result, when both are closed, the process proceeds to step S8, so the horn blowing in step S8 and the next step S9 are You can tell by the lighting of the parking lights that the doors, trunk, and hood are all completely closed. Furthermore, since the anti-theft function is automatically set in step S10 after this, the user does not need to press the send button again.

On the other hand, when it is determined in step S5 that the door courtesy is open, a portion of the door is open. In this case, the process returns to step S2 and waits for the door to close. Therefore,
This can be determined because the horn and lamp do not operate at all even when the user operates the transmit button.

When the flag is set to 1 (set) in step S11, the next time a radio wave is received, the determination is N in step S4. In this case, in step S16, an unlock output is output to bring all doors into an unlocked state. At the same time, the horn is blown twice in step S17, and the parking lamp is turned on twice in the subsequent step S18. Further, in step S19, the anti-theft function is reset, and in the next step S20, the flag is set to 0 (reset), and then the process returns to step S2.

[0025]

As described above, according to the present invention, in a vehicle anti-theft device that can be set/reset by remote control, the difference between a setting failure caused by opening a door and a setting failure caused by opening the trunk/hood can be detected by using a horn and a lamp. This can be determined from the operation mode, and when the trunk/hood is closed, the set state is automatically set without the need to operate the transmission button again, and this has the advantage of being notified by horn and lamp.
