The push buttons 6b and 6c are arranged on the arrangement surface portion 6e having different heights due to the step.
[0018]
Further, the siren 4 generates an alarm sound for a predetermined time under the control of the anti-theft device body 1. The generation time is set to 15 seconds in the initial state, but can be changed to any time from 3 to 60 seconds (details will be described later).
[0019]
Further, the sensor 2 detects the inclination of the vehicle in the left-right direction, and the sensor 3 detects the inclination of the vehicle in the front-rear direction.
[0020]
Furthermore, the indicator lamp 5 is configured to display the status of system setting, release, etc. by lighting and blinking, and as shown in FIG. 4, a light emitting portion is provided on the upper surface portion of the indicator lamp body 5a in the drawing. 5b is provided, and a double-sided tape 5c is provided on the bottom surface. And the indicator lamp 5 is affixed on the upper surface of the fuel tank 10 with the double-sided tape 5c, as shown in FIG.
[0021]
The display of the indicator lamp 5 and the operating state of the system are controlled by the anti-theft device body 1 as shown in FIG.
[0022]
The anti-theft device has the following functions.
[0023]
(1) Basic function (1) Alarm function Generates an audible alarm when sensors 2 and 3 detect changes in vehicle attitude, or when the main switch 8 is operated incorrectly (operation without system release). To do.
[0024]
As a result, a warning is given for mischief such as shaking or moving the vehicle.
[0025]
(2) When the immobilizer function system is set, the engine ignition circuit 9 is shut off so that the engine cannot be operated.
[0026]
As a result, unless the release operation is performed by the remote controller, the engine cannot be started even if the main switch 8 is illegally operated or the wiring is directly connected.
[0027]
(3) Operation display function The operation state of the system is displayed by the indicator lamp 5 as described above.
[0028]
As a result, it is displayed that the system is operating, and mischief with respect to the vehicle is suppressed.
[0029]
(2) Other functions (1) Change of siren operating time The siren operating time is set by operating the main switch 8 (details will be described later).
[0030]
Thereby, the siren operation time can be set to any time from 3 to 60 seconds.
[0031]
(2) Reduce current consumption when the sleep function system is used continuously for more than 24 hours. As shown in Fig. 7, the alarm function, immobilizer function, remote control operation and indicator lamp display are possible within 24 hours from the start of system operation, but after 24 hours, the sleep function is entered and the alarm function and immobilizer function are activated. Although it is possible, remote control operation and indicator lamp display are not possible.
[0032]
This reduces the burden on the motorcycle battery when the system is used for a long time.
[0033]
Next, the configuration and the like of the anti-theft device main body 1 will be described together with actions.
[0034]
(1) Set the system.
[0035]
The system is automatically set by turning off the main switch 8 of the motorcycle. Manual setting by the remote controller 6 is also possible.
[0036]
(1) Automatic setting As shown in FIG. 8, when the main switch 8 of the motorcycle is turned off, the indicator lamp 5 is lit for 60 seconds by the automatic setting means 12 of the anti-theft device body 1. This is a ready state, after which the indicator lamp 5 flashes about once every 2 seconds. The system is now set.
[0037]
(2) Set by remote control 6 As shown in FIG. 9, after the main switch 8 is turned OFF, when the first push button 6b of the remote control 6 is pressed, the indicator lamp 5 is set to 4 for 2 seconds by the anti-theft device body 1. After flashing once, it changes to flashing once every 2 seconds. The system is now set. In this case, unlike the case of automatic setting, setting is possible without waiting for 60 seconds.
[0038]
(2) Cancel the system.
[0039]
When the main switch 8 of the motorcycle is turned off, the system is automatically set, so it is necessary to release it before getting on the motorcycle.
[0040]
The system is released as follows (see FIG. 10).
[0041]
When the first push button 6b of the remote controller 6 is pressed, the blinking of the indicator lamp 5 is changed to lighting by the anti-theft device body 1. Note that if the siren 4 has a history of sounding while the system is operating, it will blink twice before it changes from blinking to lighting.
[0042]
When the main switch 8 of the motorcycle is turned on, the indicator lamp 5 is turned off. In this state, you can start the engine.
[0043]
(3) Disable automatic system setting.
[0044]
There are cases where you do not want to set the system automatically, such as when refueling at a gas station or when servicing a motorcycle.
[0045]
In such a case, it is possible to prevent automatic setting by performing the following operation (see FIG. 11).
[0046]
(1) When the second push button 6c of the remote control 6 is pressed while the main switch 8 is ON, an automatic set non-operation command signal is received from the remote control 6 to the remote control receiving means 13 of the anti-theft device body 1. A signal from the remote control receiving means 13 is input to the control means 11, and the control means 11 deactivates the automatic setting means 12, and the indicator lamp 5 blinks twice and then turns off. In this state, even if the main switch 8 is turned off, the alarm (system) cannot be automatically set.
[0047]
As a result, the siren 4 does not ring carelessly when refueling.
[0048]
(4) Canceling the sleep function While the sleep function is working, the remote control 6 cannot be used to cancel the system as described above. However, the alarm function and immobilizer function are in operation, so the following The system is released by operation (see FIG. 12).
[0049]
(1) A switch circuit 14 for turning on / off the power supply to the receiving circuit constituting the remote control receiving means 13 is provided. The switch circuit 14 is set in the OFF state, that is, the sleep function is activated. When the main switch 8 is turned on from this state, the power supply to the receiving circuit constituting the remote control receiving means 13 is shifted from the OFF state to the ON state by the switch circuit 14, and the indicator lamp blinks once every two seconds. As a result, the sleep function is canceled and the system is set, and in this case, the operation of the main switch 8 without the system being released is controlled by the control means 11 so that the siren 4 does not sound.
[0050]
In this way, power consumption can be reduced by the sleep function, and even if the sleep function is canceled by turning on the main switch 8, the siren 4 is not inadvertently sounded.
[0051]
Thereafter, when the first push button 6b or the second push button 6c of the remote controller 6 is pressed, the indicator lamp 5 is turned off. Thereby, the set state of the system is released, and the engine can be started in this state.
[0052]
(5) Stop the siren 4.
[0053]
By pressing the first push button 6b or the second push button 6c of the remote controller 6, the siren 4 can be stopped. When the first push button 6b is pressed, after the siren 4 stops, the system is released and reset after one minute.
[0054]
(6) Change the operation time of the siren 4.
[0055]
The operation time of the siren 4, that is, the time during which an alarm is generated from the siren 4 is set by the alarm generation time setting means 16 of the anti-theft device body 1. Here, for example, it is set to 15 seconds in the initial state. However, it can be changed by performing the following operations. The operation time (alarm generation time) of the siren 4 can be set to any time from 3 to 60 seconds.
[0056]
(1) As shown in FIG. 13, the main switch 8 is turned off.
[0057]
(2) Disconnect the connector connected to the battery power supply and connect it again. Thereby, the power-on detection means 15 of the anti-theft device body 1 is detected that the battery power is turned on, and the indicator lamp 5 is turned on.
[0058]
(3) When the main switch 8 is turned on, the siren 4 sounds, and when the time to be set has elapsed, the main switch 8 is turned off. Then, the siren 4 stops.
[0059]
Thus, the time detection means 17 detects the time from when the main switch 8 is turned on to when it is turned off after detecting that the battery power supply 7 is turned on by a signal from the power-on detection means 15. Then, the control unit 11 rewrites the set time of the alarm generation time setting unit 16 to the detection time.
[0060]
Therefore, the time from when the main switch 8 is turned on to when it is turned off (the time during which the siren 4 is ringing) is the set time.
[0061]
In addition, when resetting, it can set by performing the said operation again.
[0062]
In this way, the setting time can be changed by turning on / off the connector and turning on / off the main switch 8, so there is no need to provide a knob or a power ON / OFF switch on the anti-theft device body 1, There is no need to provide a waterproof structure.
[0063]
On the other hand, since the buttons 6b and 6c of the remote control body 6a are arranged on the arrangement surface portion 6e having different heights due to the steps, it is possible to determine which button 6b or 6c is tactilely, and the operability is good. It is. The buttons 6b and 6c are relatively large and easy to push, and the corners of the remote control main body 6a are rounded, so that the buttons 6b and 6c are easy to adjust to the hand.
[0064]
Further, since the indicator lamp 5 is attached to the upper surface of the fuel tank 10 which is a substantially horizontal plane by the double-sided tape 5c, it is not necessary to arrange a stay or the like on the vehicle body side, and the number of parts can be reduced and disposed. Workability can be improved. Further, the pasting place may be on the upper surface of the handle crown, around the meter, and in the vicinity of another indicator.
[0065]
【The invention's effect】
As described above, according to the invention described in the claims, since the alarm sound generation time can be changed by operating the main switch, it is not necessary to provide a time change knob on the anti-theft device main body, There is no need to apply structure. Even in the case of having a remote control, since this is not used when changing the setting, a practically beneficial effect of not causing an increase in the number of buttons or the like and not deteriorating operability is exhibited.
