Abstract

PURPOSE:To reliably warn even at the key operation time for preventing the key from being sealed by setting an alram unit to warning state when the fact that all openable units are locked and closed in case that the units are locked by the key. CONSTITUTION:Lock detecting means 55 for detecting the locked state of an openable unit without using a key, and a key cylinder operation detecting means 57 for detecting the fact that the unit is locked by the key are connected to lock completion detecting means 59. The means 59 detects that all units are locked irrespective of the key operation, and produces an output to burglary alarm discriminating means 61. When an engine stop signal of engine stop detecting means 51, a closed state detection signal of all units of open/closed state detecting means 53 and the locked state detection signal are inputted to the means 61, a warning unit is set to alarm state. When the means 61 detects the fact that the unit is opened without the prescribed opening operation, it warns it.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical field of the invention] This invention provides vehicle theft protection 1 [prevention 11. : Related to equipment.

[8R, Ming technology and its problems] A conventional vehicle anti-theft device shown in FIG. 1 operates on a battery 1. An ignition switch 3 is attached to each door for the roller 5, and turns ON when the C door is turned on.
Door switch 7 turns OFF when closed, hood switch 7 turns ON when opened and turns OFF when closed. (The door 1 lock detection switch 13 turns ON when the door is locked, and the key cylinder switch 1' turns ON when the door is unlocked using the key).

The controllers 1 to 0-5 detect the state of each of these switches and set the alarm state or (Yo angle 7 division state, and when in the alarm state, the normal procedure is not followed. 7, No 1
~When the rank switch 11 is turned on to the switch 9.1, it outputs an alarm signal and activates the relay 17, which drives the lights 1 to 19 and the small horn 21 and lights up the light. d3, 1 to 1"-75 (

Next, the operation will be explained according to the flowchart V-- in FIG.

Ignition 1 switch 3 is in the OFF state, opening/closing objects such as doors, hoods, trunks, etc. are in the closed state, switches 1 to 7, foot switch 9, and rank switches 1 to 11 are in the OFF state, and the door is unlocked. When the door is locked and the door lock detection switch 13 is in the ON state, controllers 1 to 1-5 set the -C release state based on this information (step 100). This corner 7 minus 4 people (2d3) (open the door l-asuiji 7
1 to 1 are turned ON, and then steps 1 to 1 are applied by operating the lock knob (67L). Then, the driver 70 lock detection switch 13 becomes FF (Steps 110 and 120). Here, the engine switch 3 and key cylinder unlock switch 15 are not ON, and the door is closed and the door switch 7 is turned on. Set the status and monitor the theft (slack 1)

When in the alert state, whether the ignition switch 3 is turned on or the

When reaching N (step 170), controller 1 - roller 5 (
, 1 returns to the release state. However, when the J5C ignition switch 3 or -1-cylinder switch 15 is not activated and remains in the OFF state,
If any one of the door, hood, or 1-rank opening/closing switch is activated and the door switch 7, foot switch 9, or I-rank switch 11 is turned ON, the controller 5 will issue an alarm. I'm in a bad state (, before)
Then, the relay 17 is activated to drive the light 19 and the bone 21 to generate an alarm (steps 180 and 190). In the alarm state, when the door is unlocked with the key and the key initiator switch 15 is turned on (step 200), the alarm state is canceled and the C release state is entered.

In the conventional vehicle theft prevention device that operates in this manner, as shown in the flow of steps 110 to 150 described above, the procedure for setting the controller 5 to the alert state involves opening the door and then operating the lock knob. This will lock the door and then close the door, which is the so-called keyless lock operation (11.1), which is only valid, so in order to prevent key 1 from entering, when you lock the door with -1-1, There was a problem with the device setup that made settings impossible.

L Invention 1-1 A3 and Summary] In view of the above, this invention has the purpose of preventing vehicle q7 tJ5 from locking ζ111 with a key. The purpose of setting the condition is to provide a device to prevent the occurrence of medium-sized meat.

In order to achieve the above object, the present invention detects whether the opening/closing II provided at the middle of the day is locked or unlocked. - Cylinder operation detection means 57, this tool - 1 - Cylinder 1'1 By inputting the operation detection means and the lock detection means 55 that detects that the opening/closing body is locked without using a key, the above-mentioned operation is performed. A locking completion detection means 59 is provided to detect that all of the opening/closing bodies are locked, and before the burglar alarm 11 alarm determination means 61 detects the stoppage of the engine from the output signal of the engine stoppage detection means 51. According to the output signal 3 of the opening/closing state detection means 53, the opening/opening direction is in the closed state, and the output signal of the locking completion detection means 5 indicates the length of the opening member -V-.
, regardless of whether the lock status has changed,
The gist is that when a predetermined opening operation is performed, it is detected that one of the opening/closing bodies is in the open state, and a Σ-information is sent.
