[0015] According to the invention of claim 1, only the owner of the vehicle who knows the password information can switch from the monitoring mode to the non - monitoring mode. Therefore, even if the key of the vehicle (for example, vehicle 4 shown in FIG. 3) is stolen or duplicated, a person attempting to steal the vehicle cannot switch the anti - theft device in the monitoring mode to the non - monitoring mode or stop the notification. Also, even if an unauthorized person tries to steal the vehicle (for example, the vehicle 4 shown in FIG. 3) by removing the battery and stopping the function of the anti-theft device (for example, the anti-theft device 1 shown in FIG. 1) of the vehicle, the engine operation is stopped, so the vehicle (for example, the vehicle 4 shown in FIG. 3) cannot be stolen. Further, when the battery is attached to operate the engine, the operation of the anti-theft device (for example, the anti-theft device 1 shown in FIG. 1) of the vehicle (for example, the vehicle 4 shown in FIG. 3) continues, so the engine operation continues to stop and a warning sound is issued. Thereby, theft of the vehicle (for example, the vehicle 4 shown in FIG. 3) can be prevented. 。

[0016] According to the invention according to claim 2, only the owner of the vehicle who knows the password information can switch from the monitoring mode to the non-monitoring mode. Therefore, even if the key of the vehicle (for example, vehicle 4 shown in FIG. 3) is stolen or duplicated, a person attempting to steal the vehicle cannot switch the anti-theft device in the monitoring mode to the non-monitoring mode or stop the notification. 。 In addition, the owner of the vehicle can set the monitoring mode while the engine is running. Thereby, even if it becomes necessary to leave the vehicle (for example, vehicle 4 shown in FIG. 3) with the engine running, theft can be prevented. 。

[0017] Claim 3 According to the invention related to Only the owner of the vehicle who knows the password information can switch from the monitoring mode to the non-monitoring mode. Therefore, even if the key of the vehicle (for example, vehicle 4 shown in FIG. 3) is stolen or duplicated, a person attempting to steal the vehicle cannot switch the anti-theft device in the monitoring mode to the non-monitoring mode or stop the notification. 。 Moreover, even if the owner of the vehicle leaves the vehicle with the engine running, since a predetermined operation when moving the vehicle (for example, vehicle 4 shown in FIG. 3) cannot be performed, theft can be prevented. 。

[0018] Therefore, according to the inventions according to claims 1 to 3, it is possible to provide an anti-theft device that more effectively prevents vehicle theft. 。

Embodiments for Carrying Out the Invention

[0024] Hereinafter, an embodiment of the anti-theft device according to the present invention will be specifically described with reference to the drawings. In the following description, when indicating the up-down, left-right directions, it shall refer to the up-down, left-right as seen from the front shown in the drawings.

[0025] <Description of the Anti-theft Device> As shown in FIG. 1, the anti-theft device 1 is mainly composed of a setting device 2 and a main body 3.

[0026] <Description of the Setting Device> The setting device 2 shown in FIG. 1 includes a housing having a left-right width (the left-right length in the drawing), for example, 7 cm, a height (the up-down length in the drawing), for example, 10 cm, and a thickness, for example, about 1 cm. And as shown in FIG. 1, on the upper left of the surface of the housing, a red LED lamp 2a1 and a green LED lamp 2a2 are provided side by side left and right. Also, as shown in FIG. 1, below those red LED lamp 2a1 and green LED lamp 2a2, four yellow LED lamps 2b are provided side by side left and right. Further, as shown in FIG. 1, below the yellow LED lamps 2b, a numeric keypad 2c is provided.

[0027] Note that the setting device 2 (see FIG. 1) includes a relay 2e (see FIG. 4) inside the housing.

[0028] <Description of the Main Body> On one hand, the main body 3 shown in FIG. 1 has a housing with a left - right width (the left - right length on the drawing) of, for example, 15.6 cm, a height (the up - down length on the drawing) of, for example, 15 cm, and a thickness of, for example, about 1.5 cm. This main body 3 (see FIG. 1) includes a relay 3b and a relay 3c (see FIG. 5) inside the housing. As shown in FIG. 1, the main body 3 is connected to the setting device 2 by a cable 3a.

[0029] Furthermore, as shown in FIG. 3, the main body 3 is connected to each part of the vehicle 4, that is, the engine 4b, the battery 4c, the horn 4d, the steering wheel 4e (more specifically, the steering - wheel horn button 4e1 shown in FIG. 5), the brake pedal and the clutch pedal 4f (more specifically, the brake - pedal switch 4f1 and the clutch - pedal switch 4f2 shown in FIG. 4), by a cable 3d (see FIG. 3), which is different from the cable 3a (see FIGS. 1 and 3) connecting the main body 3 and the setting device 2. Also, when the main body 3 (see FIG. 3) is connected to each part of the vehicle 4 (see FIG. 3), the setting device 2 (see FIG. 3) is also connected to each part of the above - mentioned vehicle 4 (see FIG. 3) via the cable 3a.

[0030] <Wiring and Circuit between Anti - theft Device and Vehicle> The connection among the setting device 2 shown in FIG. 3, the main body 3, and each part of the vehicle 4 will be further described with reference to FIGS. 4 and 5.

[0031] As shown in FIG. 4, a relay 2e provided in the setting device 2, the brake - pedal switch 4f1 and the clutch - pedal switch 4f2, and the main body 3 are connected. The brake - pedal switch 4f1 and the clutch - pedal switch 4f2 are provided in parallel with each other.

[0032] As shown in FIG. 4, the setting device 2 is provided with a battery 2d. The setting device 2 operates by the power of this battery 2d. On the other hand, the main body 3 is connected to the battery 4c as shown in FIG. 3 and operates by the power of the battery 4c.

[0033] On the one hand, as shown in FIG. 5, two circuits are connected in parallel to the battery 4c of the vehicle 4 (see FIG. 3). As shown in FIG. 5, in one of these two circuits, from the side closer to the positive side of the battery 4c, a relay 3b provided in the main body 3, an engine key switch 4g of the vehicle 4, and an engine 4b are connected. As shown in FIG. 5, in the other of the two circuits connected in parallel to the battery 4c, from the side closer to the positive side of the battery 4c, a horn 4d of the vehicle 4, a relay 3c provided in the main body 3, and a handle horn button 4e1 are connected. The relay 3c and the handle horn button 4e1 are provided in parallel with each other.

[0034] Here, the operation of the anti-theft device 1 will be briefly described. When the vehicle owner wants to prevent theft of the vehicle, such as when leaving the vehicle, the vehicle owner enters a password using the numeric keypad 2c (see FIG. 1). As a result, the anti-theft device 1 (see FIG. 1) switches to the "monitoring mode", and the relay 2e (see FIG. 4) turns ON.

[0035] During the monitoring mode, when the anti-theft device 1 detects a predetermined operation that may indicate theft, that is, when the brake pedal or clutch pedal 4f (see FIG. 3) is depressed and the brake pedal switch 4f1 or clutch pedal switch 4f2 (see FIG. 4) turns ON, a signal is input to the main body 3 (see FIG. 4). As a result, the relay 3b (see FIG. 5) of the main body 3 (see FIG. 1) switches to OFF, and the relay 3c (see FIG. 5) switches to ON. Thereby, the engine 4b (see FIG. 5) stops, and the horn 4d (see FIG. 5) sounds intermittently to notify that an abnormality has occurred.

[0036] On the other hand, when the vehicle owner does not need to prevent theft of the vehicle, such as when driving the vehicle, or when the owner wants to stop the notification, the vehicle owner enters a password or the like again using the numeric keypad 2c (see FIG. 1). As a result, the anti-theft device 1 (see FIG. 1) switches to the "non-monitoring mode", and the relay 2e (see FIG. 4) turns OFF. Further, the relay 3b (see FIG. 5) of the main body 3 (see FIG. 1) switches to ON, and the relay 3c (see FIG. 5) switches to OFF, and the anti-theft device 1 stops the notification.

[0037] The anti-theft device 1 operates as described above for a brief explanation.

[0038] <Explanation of the functional configuration of the anti-theft device> Next, with reference to FIG. 2, the functional configurations of the setting unit 2 (see FIG. 1) and the main body 3 (see FIG. 1) of the anti-theft device 1 according to the present embodiment will be described. The programs for realizing these functional configurations are stored in a non-volatile memory (not shown) in the anti-theft device 1 (see FIG. 1) and are appropriately executed by a CPU (not shown).

[0039] First, as shown in FIG. 2, the setting unit 2 includes an input unit 20, a setting unit 21, a determination unit 22, a transition unit 23, a clear unit 24, and a storage unit 25. Hereinafter, each configuration will be described.

[0040] The storage unit 25 stores a password and an initial ID. The password is a four-digit number input by the vehicle owner using the numeric keypad 2c (see FIG. 1). The setting of the password to the storage unit 25 and the clearing from the storage unit 25 will be described later. On the other hand, the initial ID is a number with a predetermined number of digits that is pre-stored in the storage unit 25 at the time of factory shipment of the anti-theft device 1 or the like. This is always stored without being cleared from the storage unit 25.

[0041] The input unit 20 receives numbers or the like input by the vehicle owner using the numeric keypad 2c (see FIG. 1) and processes them according to whether the anti-theft device 1 is in the monitoring mode or the non-monitoring mode. First, when the anti-theft device 1 is in the non-monitoring mode, the input unit 20 determines that the numbers or the like input by the owner using the numeric keypad 2c (see FIG. 1) are the password to be set in the storage unit 25 (see FIG. 2). Then, each time the owner inputs one digit using the numeric keypad 2c (see FIG. 1), one yellow LED lamp 2b (see FIG. 1) for password input confirmation is lit. When the owner inputs the fourth digit and finally inputs the # of the numeric keypad 2c (see FIG. 1), the input unit 20 turns off all the yellow LED lamps 2b (see FIG. 1) for password input confirmation and outputs the four-digit number to the setting unit 21 (see FIG. 2).

[0042] On the one hand, when the anti-theft device 1 is in the monitoring mode, the input unit 20 determines that the numbers or the like input by the owner using the numeric keypad 2c (see FIG. 1) are the password or the initial ID for shifting from the monitoring mode to the non-monitoring mode. Then, the input unit 20 temporarily stores the numbers input by the owner using the numeric keypad 2c (see FIG. 1). Finally, when the owner inputs the # of the numeric keypad 2c (see FIG. 1), the stored numbers are output to the determination unit 22 (see FIG. 2).

[0043] The setting unit 21 stores the password received from the input unit 20 (see FIG. 2) in the storage unit 25 (see FIG. 2). Then, it outputs to the shift unit 23 (see FIG. 2) that the password has been stored.

[0044] When the determination unit 22 receives from the input unit 20 the numbers input by the owner using the numeric keypad 2c (see FIG. 1), it determines whether the numbers match the password stored in the storage unit 25 (see FIG. 2). If they match, it outputs to the shift unit 23 (see FIG. 2) that they match. On the other hand, if they do not match, the determination unit 22 further determines whether they match the initial ID stored in the storage unit 25 (see FIG. 2). If they match, it outputs to the shift unit 23 (see FIG. 2) that they match.

[0045] When the shift unit 23 receives from the setting unit 21 (see FIG. 2) a signal that the password has been stored in the storage unit 25 (see FIG. 2), it shifts from the non-monitoring mode to the monitoring mode. At this time, the shift unit 23 turns on the relay 2e (see FIG. 4) in the setting device 2. Thereby, the electrical connection between the setting device 2 and the main body 3 becomes possible. Also, the red LED lamp 2a1 (see FIG. 1) provided in the setting device 2 (see FIG. 1) is lit, and the green LED lamp 2a2 (see FIG. 1) is turned off.

[0046] On the other hand, when the transition unit 23 receives a signal from the determination unit 22 (see FIG. 2) indicating that the number entered by the owner matches the password or the initial ID, it transitions from the monitoring mode to the non-monitoring mode. At this time, the transition unit 23 turns off the relay 2e (see FIG. 4) in the setting device 2. As a result, the electrical connection between the setting device 2 (see FIG. 4) and the main body 3 (see FIG. 4) is disconnected. At this time, the transition unit 23 (see FIG. 2) turns off the red LED lamp 2a1 (see FIG. 1) provided in the setting device 2, and the green LED lamp 2a2 (see FIG. 1) lights up. Then, the transition unit 23 outputs to the clear unit 24 (see FIG. 2) that it has transitioned to the non-monitoring mode.

[0047] When the clear unit 24 receives a signal from the transition unit 23 (see FIG. 2) indicating that it has transitioned to the non-monitoring mode, it clears the password stored in the storage unit 25 (see FIG. 2).

[0048] The above is the functional configuration of the setting device 2 (see FIG. 1). On the other hand, as shown in FIG. 2, the main body 3 has a first control unit 30 and a second control unit 31. Hereinafter, each configuration will be described.

[0049] When the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed during the monitoring mode, the first control unit 30 switches the control to the engine 4b (see FIGS. 3 and 5). More specifically, first, when the anti-theft device 1 is in the non-monitoring mode, or when it is in the monitoring mode but the brake pedal or the clutch pedal 4f (see FIG. 3) is not depressed, the first control unit 30 turns on the relay 3b (see FIG. 5). As a result, the electrical connection between the battery 4c (see FIG. 5) and the engine 4b (see FIG. 5) becomes possible, so when the vehicle owner turns on the engine key switch 4g (see FIG. 5), the engine 4b (see FIG. 5) starts.

[0050] When the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed while the anti-theft device 1 is in the monitoring mode, the brake pedal switch 4f1 or the clutch pedal switch 4f2 (see FIG. 4) is turned on. As a result, if the relay 2e (see FIG. 4) in the setting unit 2 is turned on, a signal is input to the main body 3 (see FIG. 4), and the first control unit 30 turns off the relay 3b (see FIG. 5). As a result, the battery 4c (see FIG. 5) and the engine 4b (see FIG. 5) are electrically disconnected, so that the engine 4b (see FIG. 5) does not operate even if the engine key switch 4g (see FIG. 5) is turned on.

[0051] When the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed during the monitoring mode, the second control unit 31 switches the control to the horn 4d (see FIG. 5). More specifically, first, when the anti-theft device 1 is in the non-monitoring mode, or when it is in the monitoring mode but the brake pedal or the clutch pedal 4f (see FIG. 3) is not depressed, the second control unit 31 turns off the relay 3c (see FIG. 5). As a result, the electrical connection between the steering wheel horn button 4e1 (see FIG. 5), the relay 3c (see FIG. 5), and the battery 4c (see FIG. 5) is disconnected, so that the horn 4d (see FIG. 5) does not sound unless the vehicle owner presses the steering wheel horn button 4e1 (see FIG. 5).

[0052] On the other hand, when the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed while the anti-theft device 1 is in the monitoring mode, the brake pedal switch 4f1 or the clutch pedal switch 4f2 (see FIG. 4) is turned on. As a result, since the setting unit 2 (see FIG. 4) and the main body 3 (see FIG. 4) are electrically connected, a signal is input to the main body 3 (see FIG. 4). As a result, the second control unit 31 repeatedly turns on the relay 3c (see FIG. 5) for 5 seconds and then turns it off for 1 second. As a result, the horn 4d (see FIG. 5) sounds intermittently and repeats sounding for 5 seconds and then stopping for 1 second.

[0053] <Description of the processing content of the anti-theft device> Next, with reference to the flowchart shown in FIG. 6, the processing content of the anti-theft device 1 shown in this embodiment will be described.

[0054] First, the setting unit 21 (see FIG. 2) sets a password in the storage unit 25 (see FIG. 2) (step S1). More specifically, first, when the input unit 20 (see FIG. 2) starts receiving an input by the vehicle owner using the numeric keypad 2c (see FIG. 1), it checks whether a password is stored in the storage unit 25 (see FIG. 2). If not stored, it is determined that the anti-theft device 1 is in the non-monitoring mode. Therefore, each time the owner inputs one digit using the numeric keypad 2c (see FIG. 1), the input unit 20 (see FIG. 2) lights one yellow LED lamp 2b (see FIG. 1) for password input confirmation. Then, when the owner inputs four digits and finally inputs the # of the numeric keypad 2c (see FIG. 1), the input unit 20 (see FIG. 2) turns off all the yellow LED lamps 2b (see FIG. 1) for password input confirmation and outputs the four digits to the setting unit 21 (see FIG. 2). The setting unit 21 (see FIG. 2) stores the four digits received from the input unit 20 (see FIG. 2) in the storage unit 25 (see FIG. 2) and outputs to the transition unit 23 (see FIG. 2) that the password has been stored.

[0055] Next, the transition unit 23 (see FIG. 2) makes a transition to the monitoring mode (step S2). More specifically, when the transition unit 23 (see FIG. 2) receives a signal indicating that the password has been stored from the setting unit 21 (see FIG. 2), it makes a transition from the non-monitoring mode to the monitoring mode. That is, the relay 2e (see FIG. 4) inside the housing of the setting device 2 (see FIG. 1) is turned ON. Thereby, an electrical connection between the setting device 2 (see FIG. 4) and the main body 3 (see FIG. 4) becomes possible. Further, the transition unit 23 (see FIG. 2) lights the red LED lamp 2a1 (see FIG. 1) provided in the setting device 2 (see FIG. 1), and the green LED lamp 2a2 (see FIG. 1) is turned off. The owner can confirm that it is in the monitoring mode by the fact that the red LED lamp 2a1 (see FIG. 1) is lit.

[0056] Next, the owner starts the engine 4b (see FIG. 5) with the key (step S3). That is, when the owner operates the key to start the engine, the engine key switch 4g shown in FIG. 5 turns ON, and the battery 4c (see FIG. 5) and the engine 4b (see FIG. 5) are electrically connected. Here, when the first control unit 30 (see FIG. 2) is in the monitoring mode and the brake pedal or the clutch pedal 4f (see FIG. 3) is not depressed, as shown in FIG. 5, the relay 3b is turned ON to make the battery 4c (see FIG. 5) and the engine 4b (see FIG. 5) electrically connectable. Therefore, the engine 4b (see FIG. 5) starts.

[0057] In this way, even when the engine 4b (see FIG. 5) operates in the monitoring mode, the anti-theft device 1 does not notify that an abnormality has occurred. However, just starting the engine 4b (see FIG. 5) does not allow the vehicle to start, and if the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed to start the vehicle, as will be described later, the anti-theft device 1 notifies that an abnormality has occurred. Therefore, even if the owner leaves the vehicle with the engine 4b (see FIG. 5) running, the vehicle cannot be moved, so theft can be prevented.

[0058] Also, when the second control unit 31 (see FIG. 2) is in the monitoring mode and the brake pedal or the clutch pedal 4f (see FIG. 3) is not depressed, as shown in FIG. 5, the relay 3c is turned OFF. Thereby, the electrical connection between the steering wheel horn button 4e1 (see FIG. 5), the relay 3c (see FIG. 5), and the battery 4c (see FIG. 5) is disconnected. Therefore, the horn 4d (see FIG. 5) does not sound unless the steering wheel horn button 4e1 (see FIG. 5) is pressed.

[0059] Note that it is also possible to first start the engine 4b (see FIG. 5) with the key (step S3), and then perform the setting of the password (step S1) and the transition to the monitoring mode (step S2). Thereby, the owner can shift to the monitoring mode with the engine running.

[0060] Next, the first control unit 30 and the second control unit 31 wait for the depression of the brake or the clutch (step S4). More specifically, when the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed, it waits for a signal indicating that the brake pedal switch 4f1 or the clutch pedal switch 4f2 shown in FIG. 4 has turned ON.

[0061] Next, the first control unit 30 (see FIG. 2) stops the engine 4b (see FIG. 5) (step S5). More specifically, when the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed in the monitoring mode, the main body 3 (see FIG. 4) receives a signal indicating that the brake pedal switch 4f1 or the clutch pedal switch 4f2 shown in FIG. 4 has turned ON. In response to this, the first control unit 30 (see FIG. 2) of the main body 3 (see FIG. 2) turns OFF the relay 3b (see FIG. 5) and electrically disconnects the battery 4c (see FIG. 5) and the engine 4b (see FIG. 5) as a means of notifying that an abnormality has occurred, thereby stopping the engine 4b (see FIG. 5).

[0062] Next, the second control unit 31 (see FIG. 2) sounds the horn 4d (see FIG. 5) (step S6). More specifically, when the brake pedal or the clutch pedal 4f (see FIG. 3) is depressed in the monitoring mode, the main body 3 (see FIG. 4) receives a signal indicating that the brake pedal switch 4f1 or the clutch pedal switch 4f2 shown in FIG. 4 has turned ON. In response to this, the second control unit 31 (see FIG. 2) of the main body 3 (see FIG. 2) turns on the relay 3c (see FIG. 5) as a means of notifying that an abnormality has occurred, and electrically connects the horn 4d (see FIG. 5), the relay 3c (see FIG. 5), and the battery 4c (see FIG. 5) to sound the horn 4d (see FIG. 5). Note that the second control unit 31 (see FIG. 2) repeatedly turns on the relay 3c (see FIG. 5) for 5 seconds and then turns it off for 1 second in order to intermittently sound the warning sound of the horn 4d (see FIG. 5). In this way, the second control unit 31 (see FIG. 2) intermittently sounds the warning sound of the horn 4d (see FIG. 5) until it shifts to the non-monitoring mode as described later or until the power of the vehicle battery 4c (see FIG. 5) runs out. Thereby, it is possible to surely notify the owner that the vehicle has been stolen, and by notifying intermittently, consideration for the surroundings can be given compared to the case of continuously sounding the horn 4d (see FIG. 5).

[0063] Note that once the brake pedal switch 4f1 or the clutch pedal switch 4f2 shown in FIG. 4 turns ON, even if the depression of the brake pedal or the clutch pedal 4f (see FIG. 3) is released thereafter, the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) maintain the OFF state of the relay 3b (see FIG. 5) and the intermittent ON state of the relay 3c (see FIG. 5).

[0064] Also, when the battery 4c (see FIG. 5) is removed from the vehicle, the warning sound of the horn 4d (see FIG. 5) stops. However, as described above, the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) can maintain the OFF state of the relay 3b (see FIG. 5) and the intermittent ON state of the relay 3c (see FIG. 5). Therefore, when the battery is attached again, the engine 4b (see FIG. 5) continues to stop operating, and the horn 4d (see FIG. 5) emits a warning sound. That is, even if the battery is removed to stop the function of the vehicle anti-theft device 1 and an attempt is made to steal the vehicle, when the battery is attached again to start the vehicle, the anti-theft device 1 continues to notify that an abnormality has occurred. This can prevent the vehicle from being stolen.

[0065] Next, when the owner inputs a password using the numeric keypad 2c (see FIG. 1) to stop the notification, the determination unit 22 (see FIG. 2) checks whether it matches the set password (step S7). More specifically, first, when the input unit 20 (see FIG. 2) detects that the vehicle owner has started input using the numeric keypad 2c (see FIG. 1), it checks whether the password is stored in the storage unit 25 (see FIG. 2). If it is stored, the input unit 20 (see FIG. 2) determines that the number or the like input by the owner using the numeric keypad 2c (see FIG. 1) is the password or the initial ID for shifting from the monitoring mode to the non-monitoring mode. Therefore, the number input by the owner using the numeric keypad 2c (see FIG. 1) is temporarily stored. Finally, when the owner inputs the # on the numeric keypad 2c (see FIG. 1), the stored number is output to the determination unit 22 (see FIG. 2).

[0066] When the determination unit 22 (see FIG. 2) receives the number input by the owner using the numeric keypad 2c (see FIG. 1) from the input unit 20 (see FIG. 2), it determines whether the number matches the password stored in the storage unit 25 (see FIG. 2) by the setting unit 21 (see FIG. 2) in step S1. If they match, it outputs the fact of the match to the transition unit 23 (see FIG. 2). On the other hand, if they do not match, the determination unit 22 further determines whether it matches the initial ID stored in the storage unit 25 (see FIG. 2), and if they match, it outputs the fact of the match to the transition unit 23 (see FIG. 2). Note that the processes of steps 5 to 7 are repeated until there is a match with either the password or the initial ID.

[0067] Next, a transition to the non-monitoring mode is performed (step S8). More specifically, when the transition unit 23 (see FIG. 2) receives a signal from the determination unit 22 (see FIG. 2) that the number input by the owner matches the password or the initial ID, it transitions from the monitoring mode to the non-monitoring mode. Note that by allowing a transition to the non-monitoring mode even when the initial ID is input, it is possible to transition to the non-monitoring mode even if the password information is accidentally forgotten.

[0068] When transitioning from the monitoring mode to the non-monitoring mode, the transition unit 23 (see FIG. 2) turns off the relay 2e (see FIG. 4) inside the housing of the setting device 2 (see FIG. 1). Thereby, the electrical connection between the setting device 2 (see FIG. 4) and the main body 3 (see FIG. 4) is disconnected. Also, the transition unit 23 (see FIG. 2) turns off the red LED lamp 2a1 (see FIG. 1) provided on the setting device 2 (see FIG. 1), and turns on the green LED lamp 2a2 (see FIG. 1). Then, the transition unit 23 outputs the fact that it has transitioned to the non-monitoring mode to the clearing unit 24 (see FIG. 2).

[0069] Note that when the relay 2e (see FIG. 4) in the housing of the setting device 2 (see FIG. 1) is turned off, the first control unit 30 turns on the relay 3b (see FIG. 5) to enable the electrical connection between the battery 4c (see FIG. 5) and the engine 4b (see FIG. 5). Then, the second control unit 31 turns off the relay 3c (see FIG. 5) to disconnect the electrical connection between the horn 4d (see FIG. 5), the relay 3c (see FIG. 5), and the battery 4c (see FIG. 5). Therefore, when shifting to the non-monitoring mode, the notification stops.

[0070] Finally, the clear unit 24 (see FIG. 2) clears the set password (step S9). More specifically, when receiving a signal from the shift unit 23 (see FIG. 2) indicating a shift to the non-monitoring mode, the clear unit 24 (see FIG. 2) clears the password set in the storage unit 25 (see FIG. 2). Since the password is cleared every time in this way, the owner has to set the password every time when switching to the monitoring mode (step S1). By setting the password information every time in this manner, it is possible to reduce situations such as forgetting the password information and being unable to switch to the non-monitoring mode.

[0071] According to the present embodiment described above, only the owner of the vehicle who has set the anti-theft device 1 to the monitoring mode by inputting the password using the numeric keypad 2c (see FIG. 1) knows the password. Therefore, only the owner of the vehicle can switch from the monitoring mode to the non-monitoring mode. Thus, even if the key of the vehicle (for example, the vehicle 4 shown in FIG. 3) is stolen or duplicated, a person attempting to steal the vehicle cannot switch the anti-theft device in the monitoring mode to the non-monitoring mode, start the engine 4b (see FIG. 5), or stop the intermittently sounding horn 4d (see FIG. 5).

[0072] From the above, according to the present embodiment, it is possible to provide an anti-theft device that can more effectively prevent vehicle theft.

[0073] <Description of Modification Example> Note that the anti-theft device shown in this embodiment is merely an example, and various modifications and changes are possible within the scope of the gist of the present invention described in the claims. Also, the conceptual circuit diagrams shown in FIGS. 3 to 5 can be variously modified and changed within the scope of the gist of the present invention described in the claims, and may be embodied by a circuit or by information processing. For example, in this embodiment, when switching between the monitoring mode and the non-monitoring mode, the transition unit 23 (see FIG. 2) turns the relay 2e (see FIG. 4) ON or OFF, but it is not limited to this. For example, without providing the relay 2e (see FIG. 4), the transition unit 23 (see FIG. 2) may be programmed to notify the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) of the mode change by communication. Then, the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) may store that they are in the monitoring mode, and when the main body 3 (see FIG. 4) receives a signal that the brake pedal or the clutch pedal 4f (see FIG. 3) has been depressed, they may turn the relay 3b (see FIG. 5) and the relay 3c (see FIG. 5) ON or OFF.

[0074] Also, in this embodiment, the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) control the operations of the engine 4b (see FIG. 5) and the horn 4d (see FIG. 5) by turning the relay 3b (see FIG. 5) and the relay 3c (see FIG. 5) ON or OFF, but it is not limited to this. For example, the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) may be programmed to directly control the operations of the engine 4b (see FIG. 5) and the horn 4d (see FIG. 5).

[0075] Also, in this embodiment, the second control unit 31 (see FIG. 2) intermittently sounds the warning sound of the horn 4d (see FIG. 5). In this regard, for example, a flicker relay (not shown) may be arranged in series with the relay 3c (see FIG. 5) so that it turns ON for 5 seconds and then OFF for 1 second and repeats this.

[0076] Also, in this embodiment, when the brake pedal switch 4f1 or the clutch pedal switch 4f2 shown in FIG. 4 is once turned ON, even if the depression of the brake pedal or the clutch pedal 4f (see FIG. 3) is then released, the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) maintain the OFF state of the relay 3b (see FIG. 5) and the intermittent ON state of the relay 3c (see FIG. 5). In this regard, for example, a non-volatile memory may be used to store the ON / OFF states of the relay 3b (see FIG. 5) and the relay 3c (see FIG. 5), or it may be configured with a keep relay. Alternatively, when the first control unit 30 (see FIG. 2) turns the relay 3c (see FIG. 5) ON or OFF, the non-volatile memory (not shown) in the main body 3 may store whether it is in the notification state or the notification stop state, and the first control unit 30 (see FIG. 2) and the second control unit 31 (see FIG. 2) may be configured to appropriately check the non-volatile memory.

[0077] In this embodiment, the main body 3 and the setting device 2 are connected by wire using the cable 3a (see FIG. 1), but this may be replaced by wireless using, for example, a wireless communication technology conforming to the Bluetooth standard.

[0078] Also, in this embodiment, the input unit 20, the setting unit 21, the determination unit 22, the transition unit 23, the clear unit 24, and the storage unit 25 are configured as the functional components of the setting device 2, and the first control unit 30 and the cable 3a connecting the main body 3 and the setting device 2 are configured as the functional components of the main body 3 (see FIG. 2), but it is not limited to this. For example, the transition unit 23 (see FIG. 2) may be configured as a functional component on the main body 3 side. In that case, the setting unit 21 and the determination unit 22 may be appropriately configured, such as outputting to the transition unit 23 via the cable 3a (see FIG. 1) connecting the main body 3 and the setting device 2.

[0079] Also, in this embodiment, the main body 3 and the setting device 2 are connected by wire using a cable 3a (see FIG. 1). However, as the setting device 2 (see FIG. 1), a terminal device such as the owner's smartphone of the vehicle may be used, and this may be paired and connected to the main body 3 by wireless communication using a wireless communication technology such as the Bluetooth standard. Further, in that case, among the functional configurations of the setting device 2 in this embodiment, only the input unit 20 (see FIG. 2) may be the functional configuration of the terminal device, and the setting unit 21, the determination unit 22, the transition unit 23, the clear unit 24, and the storage unit 25 may be the functional configurations on the main body 3 side. In that case, if the terminal device appropriately receives information on whether the main body 3 is in the monitoring mode or the non-monitoring mode from the main body 3 (see FIG. 1), the same operation as the input unit 20 in this embodiment is possible.
