Description

DETAILED DESCRIPTION OF THE INVENTION <Industrial field of application> The present invention relates to a vehicle-mounted security device, and more particularly to a vehicle-mounted security device that is suitable for application when security is activated from a vehicle-mounted security operation panel.

<Prior Art> An anti-theft device (security device) that prevents a car from being stolen is used by someone else to open the car door, give a considerable shock to the car, or open the trunk to steal the car while security is activated. Alternatively, when the vehicle enters the vehicle, the siren is sounded, or the headlights of the vehicle are blinked, and the starter cut (to prevent the engine from starting) or fuel cut is performed to prevent the vehicle from running and theft is prevented.

The security operation of the in-vehicle security device is started and stopped by operating a key provided on the in-vehicle security operation panel or a portable remote control unit.

In order to activate the security from the in-vehicle security operation panel, command the activation of the security by key operation, exit the car, and close all doors, and the security will activate after the set time.

<Problems to be Solved by the Invention> By the way, the conventional method of activating the security from the in-vehicle security operation panel has the following problems. In other words, after the security operation command, before the set time has elapsed after closing all the doors, that is, before the security is activated, you may notice that the forgotten item or the interior light is lit, or you may have to open the door or trunk for other reasons. May open. In this case, while opening the door or trunk,
When the set time elapses, the security is activated. When the security is activated, the door and the trunk are immediately opened, so that the door sensor and the trunk sensor immediately detect the opening of the door and the trunk, which causes a problem that the siren suddenly sounds and the headlight of the automobile blinks.

In view of the above, an object of the present invention is to provide a vehicle-mounted security device that does not enter into a security operating state even if a door or a trunk is opened before the security operation is started.

Another object of the present invention is to prevent the security from operating by interrupting the elapsed time measurement even if the door or trunk is opened before the security is activated, and restarting the elapsed time measurement after the door is closed. An object is to provide a vehicle-mounted security device.

<Means for Solving the Problem> In the present invention, the above-mentioned problem is solved by a vehicle-mounted security operation panel, a sensor for detecting opening / closing of a door or a trunk, a time-measuring means for measuring elapsed time, and a security control for activating security. And means for controlling elapsed time.

<Operation> When a predetermined key on the security operation panel is operated and all the doors and trunks of the car are closed to measure the elapsed time, the security is activated when the elapsed time exceeds the set time. When the door or trunk is opened before the elapsed time reaches the set time, the elapsed time is stopped, and when the door or trunk is closed again, the time is restarted.

<Embodiment> FIG. 1 is a block diagram of a security device according to the present invention. Reference numeral 1 denotes a portable transmission unit (remote control unit), which is capable of transmitting a security operation command (amming command) and a security operation cancellation command (disarming command) to the in-vehicle security device body by pressing a key.

Is an arming command generator that outputs an arming command KAM in a timely manner according to a request from the security operation panel, and 26 is a security controller.

The security operation panel 23 is provided with a ten-key 23a, a set key 23b requiring security, a code key 23c operated when an ID code is input, and the like. When a security operation request is issued from the security operation panel 23, the arming command generation unit 25 outputs an arming signal KAM after a set time has elapsed after the door and trunk are closed. The security control unit 26 responds to an arming command sent from the remote control unit 1 or an arming command KAM output from the arming command generation unit 25 in response to a request from the security operation panel 23, in a security operating state (theft prevention operating state). ).

Reference numeral 3 denotes a detection unit that detects opening / closing of a door, opening / closing of a trunk, turning on / off of an ignition switch, vibration, etc., and is provided with a door opening / closing sensor 31, a trunk opening / closing sensor 32, an ignition sensor 33, a vibration sensor 34, and the like. There is.

Reference numeral 4 denotes an anti-theft unit that, when an abnormality is detected by each sensor during security operation, turns off the siren driver 41 that turns on the siren by the siren drive signal SDR output from the security control unit 26 and the headlight by the blinking drive signal BLD. It has a blinking light driver 42.

Reference numeral 5 denotes an engine control unit, which is used when an abnormality is detected by each sensor during security operation.
The signal ESP output from 26 performs engine start cut or fuel cut to prohibit engine start.

FIG. 2 is a flow chart of the arming command generation control of the present invention, and the overall operation of FIG. 1 will be described below with reference to this flow chart.

The set key 23b on the security operation panel 23 is pressed,
After that, when all the doors and the trunk are closed (steps 101 and 102), the arming command generation unit 25 causes the timer 24
To start measuring the elapsed time t (step 10
3). The elapsed time t may be timed when the set key 23b is operated.

After that, the elapsed time t is a predetermined time ts that is set in advance.
It is monitored whether (any program can be set in 0 to 45 seconds) (step 104), and if t ≧ ts, the arming command KAM is output to the security control unit 26 to enter the security operating state and the process is terminated ( Step 105).

However, if t <ts, refer to the outputs of the sensors 31 and 32 to check that the door or trunk is opened (step 10
6) If not open, jump to step 103, continue counting the elapsed time, and repeat the subsequent processing.

On the other hand, if any door or trunk opens,
Immediately, the timer 24 is started to interrupt the measurement of the elapsed time (step 107).

Next, referring to the output of the ignition sensor 33, it is checked whether or not the ignition switch is turned on (step 108), and if it is turned on, the elapsed time t is cleared to zero and the processing is terminated by setting the disarming state (step 109). .

However, if the ignition switch is not on,
It is checked whether all the doors and the trunk are closed (step 110). If not closed, the processing from step 107 is repeated, and if closed, the process jumps to step 103 to restart the counting of elapsed time and the subsequent processing is repeated.

In summary, when the elapsed time t reaches or exceeds the set time ts without opening the door or trunk, the security is activated at that point. Also, if the door or trunk opens for some reason before the elapsed time t exceeds the set time ts, the elapsed time measurement stops, and when the use ends and the door or trunk closes again, the elapsed time measurement resumes. When the elapsed time t exceeds the set time ts, the security is activated at that point. Therefore, the security is not activated during the supplement.

FIG. 3 is a block diagram of another embodiment of the present invention, in which the same parts as those in FIG. 1 are designated by the same reference numerals. In the figure, 23 is a security operation panel, 26 is a security control unit, 31 is a door sensor, 32 is a trunk sensor, and 33 is an ignition sensor. Further, 51 is a timer for measuring the elapsed time since the set key on the security operation panel 23 was operated, or the elapsed time after the key was operated and all the doors and trunks of the car were closed, and 52 was set. A register for storing the time ts, 53 compares the elapsed time t with the set time ts, and outputs a arming command KAM when the elapsed time exceeds the set time, and 54 is a timer for measuring the elapsed time t. (1) Elapsed time since the set key on the security operation panel 23 was operated, or the elapsed time since the key was operated and all car doors and trunks were closed. (2) When the door or the trunk is opened before the elapsed time t reaches the set time ts, the timer 41 is stopped to stop the elapsed time measurement, and then, Again When the door and the trunk are all closed, the timer is started and the elapsed time is restarted.

<Effect of Device> According to the present invention as described above, the elapsed time since the predetermined key on the security operation panel was operated, or the elapsed time after the key was operated and all the doors and trunks of the car were closed. When the elapsed time exceeds the set time,
Along with activating security, it is configured to interrupt the elapsed time measurement when the door or trunk is opened before the elapsed time reaches the set time, and restart the time measurement when the door or trunk is closed again. Therefore, even if you notice that the forgotten item, the interior light, etc. are turned on before the security is activated, or if you open the door or trunk for other reasons, the set time elapses during that time and the siren is activated. It does not ring or the car headlights flash.
