Description

[0001]
BACKGROUND OF THE INVENTION
  The present invention relates to a vehicle, that is, a motorized bicycle, a motorcycle, a small work vehicle, or a small planing boat (Personal Watercraft) that jets a water flow backward and sails forward on the water by its reaction force; (Also referred to as PWC) or the so-called “snowmobile” or the like, the driver's seat is open to the outside and anyone can get in, the anti-theft device used in the vehicleAnd vehicle equipped with antitheft deviceAbout.
[0002]
[Prior art]
A vehicle such as a motorcycle has a configuration in which a driver's seat is opened to the outside so that anyone can get in the driver's seat.
In addition, so-called key switches are arranged in the vicinity of the driver's seat, specifically, in an exposed portion such as an instrument panel in front of the driver's seat.
[0003]
For this reason, in the case of this type of vehicle, the anti-theft performance is inferior compared to a four-wheeled vehicle having a configuration in which the driver's seat is isolated from the outside and the user (driver) cannot enter.
[0004]
Under such circumstances, in a vehicle such as a motorcycle, the vehicle user holds a card for transmitting a vehicle-specific signal, and a receiver capable of receiving the signal is provided on the vehicle side. There is. In the case of such an anti-theft device, when a vehicle is to be used, a predetermined matching key is inserted into a key switch that is a main switch provided on the vehicle and rotated to a predetermined position (ON position). The engine can be started only when a predetermined signal is received from the card side (see Patent Document 1).
[0005]
Also, as a known theft device, there is known a motorcycle in which an IC chip in which a secret code is stored is embedded in a key to be inserted into a main switch, and an engine cannot be started even if another key is inserted. Yes.
[0006]
[Patent Document 1]
Japanese Patent No. 311585
[0007]
[Problems to be solved by the invention]
However, in the case of the anti-theft device using the former card, the vehicle user always uses the key to be inserted into the main switch and the card having the transmission function. Cannot be done, and the pockets and the like become bulky. Also, if either one is lost, there is a disadvantage that the vehicle cannot be used immediately. Also, if the battery built into the card runs out, the vehicle may suddenly become unusable.
[0008]
The anti-theft device of the type in which the latter IC chip is embedded in the key also has a disadvantage that the key itself becomes large and uncomfortable when it is put in a pocket or the like.
[0009]
In addition, in the case of this type of vehicle, the area of the instrument panel arranged in front of the driver's seat is small, and specifically, only about the area where meters such as speedometers and tachometers are arranged can be taken. It is difficult to adopt a publicly known configuration in which a numeric keypad and a display unit are arranged on a console panel or the like and a personal identification code is input, as used in a known four-wheeled vehicle.
[0010]
  The present invention has been made under such circumstances, so that the vehicle can be used without carrying around extra cards, etc., and the key itself is not enlarged, and theft can be prevented. In addition, an anti-theft device that does not require a large instrument panelAnd vehicle equipped with antitheft deviceThe purpose is to provide.
[0011]
[Means for Solving the Problems]
  The present invention can solve the above problems by an antitheft device having the following configuration. That is,
  The anti-theft device according to the first aspect of the present invention is an anti-theft device mounted on a vehicle in a form in which the driver's seat is opened to the outside and anyone can get into the driver's seat,
  A specific code consisting of a plurality of predetermined codes is fixed to the A button for selecting a code and the code selected with the A button, or the code selected with the A button is fixed and the next code is By using the B button to shift to the position to be entered,
  The ECU that controls the operation of the vehicle driving engine is configured to be in an operating state.And
  The anti-theft device further has a timer function, and after the operation of the anti-theft device is canceled, when the timer function is set, the anti-theft device operates until a predetermined time elapses after the timer is set. Configured to delay the restart ofIt is characterized by that.
  The anti-theft device according to the second aspect of the present invention is an anti-theft device mounted on a vehicle in a form in which a driver's seat is opened to the outside and anyone can get in the driver's seat,
By inputting a specific code consisting of a plurality of predetermined codes using a button,
The ECU that controls the operation of the vehicle driving engine is configured to be in an operating state,
  The anti-theft device further has a timer function, and after the operation of the anti-theft device is canceled, the timer function prevents the anti-theft from the setting of the timer function until a predetermined time elapses. The apparatus is configured to be turned off.
  According to a third aspect of the present invention, there is provided a vehicle including the antitheft device.
[0012]
Thus, according to the antitheft device configured as described above, the user simply stores a predetermined password, and then operates the A and B buttons to operate the password. If a code that matches the code is input, the ECU that controls the operation of the engine can be put into an operating state. Therefore, the user does not need to carry a card or a large key in which an IC chip is embedded to transmit a bulky password. Further, since only the A button and the B button need be arranged on the vehicle side, it is possible to arrange the instrument panel with a small area without requiring a large area for arranging the numeric keypad. However, the arrangement location on the vehicle is not limited to the instrument panel described above, and may be arranged at other locations.
[0013]
Further, in the anti-theft device, when the input series of codes is erroneously entered in the light of the specific password and continuously input a predetermined number of times or more, the subsequent input is invalidated, If the ECU is configured to be inoperable, even if a person who wants to steal enters the PIN code multiple times by trial and error, the input after a predetermined number of times becomes meaningless, and the anti-theft function is improved. To do. In other words, the possibility that a code that coincides with the code is accidentally input is reduced, and it becomes difficult to use other than the owner of the vehicle. In the case of such a configuration, it is preferable that the ECU that has become inoperable in this way is configured to be released when some reset operation or a predetermined time elapses.
[0014]
Further, in the anti-theft device, the A button and the B button are provided on the instrument panel in front of the driver's seat, and a display device for displaying the input code is disposed on or near the instrument panel. Thus, it is a practically preferable configuration that is easy to operate and easy to see the display on the display device.
[0015]
Further, in the anti-theft device, the display device is configured so that the switching means can switch between the input code and a trip meter display indicating a vehicle travel distance or an engine operating time. The device can be used as a display device for a plurality of objects, and is a more preferred anti-theft device in terms of space saving.
[0016]
Furthermore, in the anti-theft device, the display device is configured to be able to switch between the input code and either the vehicle running speed or the engine speed by switching means. It can be used as a display device for the target object, and is a more preferable antitheft device.
[0017]
The antitheft device further includes a key switch for enabling input of the A button and B button, and the input of the A button and B button becomes effective only after the key switch is turned ON. When the display device is configured to display, the anti-theft device has good operability.
[0018]
Further, in the anti-theft device, the anti-theft device can cancel the operation of the anti-theft device thereafter after the input code is matched with the specific code. When configured, for example, when a user puts a vehicle (for example, a motorcycle) into a gas station or the like, and removes the key from the key hole to refuel, the tank cap is unlocked. Then, even in a situation where the ECU is deactivated and the antitheft device operates, the antitheft device does not operate. Therefore, after refueling is completed, there is no need to input the password again to release the antitheft device.
[0019]
Further, in the antitheft device, the antitheft device has a timer function, and even if the operation condition of the antitheft device is satisfied after the operation of the antitheft device is canceled, the antitheft device is set by the timer function. Until the predetermined time (timer set time) elapses, the timer function delays the operation of the anti-theft device. There is no need to enter the password again after completion. In addition, a situation where the operating condition of the antitheft device is satisfied after the predetermined time elapses, for example, a situation where a user performs a service at a gas station after refueling without inserting a key into the keyhole. Then, since the anti-theft device is activated again after the predetermined time has elapsed, it is possible to prevent the vehicle from being stolen in such a situation.
[0020]
Further, in the anti-theft device, the anti-theft device may change the specific code to another code after the inputted series of codes are matched with the specific code. If it is configured to be able to do so, the security code can be changed as appropriate according to the user's intention, so that the anti-theft function is further improved.
[0021]

The cell motor Ms is mechanically connected to the engine E and configured to start the engine.
[0029]
As the alarm device 5, various devices can be considered. For example, a hazard lamp, an alarm buzzer, a passing lamp, or the like can be considered.
[0030]
In the present embodiment, a liquid crystal display is used as the display device 4. The display device 4 displays the input code, and when the engine E is operated (becomes operating state), the display content is automatically switched, and the trip distance (unit “ km ") can be displayed.
[0031]
Specifically, as shown in FIG. 2, the A button 2 (2A, 2B), the B button 3 and the display device 4 are arranged in front of the riding seat of a motorcycle (rider seat). Specifically, it is arranged on an instrument panel Pi arranged above a headlamp (not shown) in front of the bar-type handle.
[0032]
In the case of this embodiment, an immobilizer warning light 6 that prompts the input of a personal identification code is arranged on the instrument panel Pi (see FIG. 2).
[0033]
As shown in FIG. 1, the immobilizer warning light 6 is configured such that electricity is supplied via the electric wire L6 branched from the electric wire L1 supplying power to the display device 4 and the vehicle body, as shown in FIG. Has been.
[0034]
The anti-theft device body 1 includes an arithmetic device and a storage device in which an anti-theft control program and a password are stored, although not shown.
[0035]
The anti-theft device body 1 is connected to the switch SW3 by a control line L10, and is configured to perform ON / OFF control of the switch SW3. The anti-theft device body 1 is connected to the switch SW2 by a control line L11, and is configured to perform ON / OFF control of the switch SW2.
[0036]
In this embodiment, the anti-theft device body 1 is disposed below the seat S of the motorcycle Vh shown in FIG.
[0037]
In FIG. 2, 10 is a speed meter that displays the speed of the motorcycle, 11 is a tachometer that displays the number of revolutions of the engine E, 12 is a fuel meter, 13 is a water temperature meter that displays the temperature of cooling water of the engine, and 14 Is a clock (also serves as a trip meter by a changeover switch), 15 is a headlamp lighting switch, 16 is a direction indicator lamp, and 17 is a neutral lamp. In FIG. 7, Tn is a fuel tank, Cs is a side cowling that covers the side of the engine, Cf is a front cowling that covers the front of the vehicle body, Wf is a front wheel, Wr is a rear wheel, and Ch is a rear wheel from the engine. This is a drive chain that transmits power to Wr.
[0038]
Thus, the antitheft device configured as described above operates as follows. The operation of the antitheft device will be described below together with the control contents of the antitheft control program. That is, when explaining along the flowchart of FIG.
When the owner of the motorcycle inserts the held key into the switch SW1 that is the key switch of the motorcycle and rotates it to the “ON” position, the switch SW1 is turned on (energized state) (step 1). (S1)). As a result, power is supplied from the DC power source Bt to the anti-theft device body 1, and the display device 4 and the immobilizer warning light 6 are turned on (step 2 (S2)). In order to evoke the input operation of the code code, it is preferable to attach a flasher (not shown) to the immobilizer warning light 6 so that the immobilizer warning light 6 lights up in a blinking manner. .
[0039]
In this state, a preset code is input (step 3 (S3)). That is, by operating the A button 2 (2A, 2B) and selecting a numerical value to be input, when a predetermined numerical value is displayed on the display device 4, the B button 3 is pressed to fix the numerical value. , Shift one digit. In this way, numerical values are sequentially input in correspondence with the passwords for the required number of digits. Note that the “shift by one digit” function of the B button 3 is not the B button 3 but is input in the theft control program after the A button 2 (2A, 2B) is input, for a predetermined time (for example, 8 (Second), when the signal does not enter from the A button 2, it may be configured to automatically shift by one digit.
[0040]
When the code corresponding to the predetermined password is input by the predetermined number of digits (step 4 (S4)), specifically, when the B button 3 is pressed after the last numerical value is input, the anti-theft is prevented. The arithmetic unit of the apparatus main body 1 checks whether or not the password code stored in the storage device matches the input password code (step 5 (S5)).
[0041]
Next, as a result of the collation, if the input password matches the password stored in advance, the process proceeds to step 6 (S6), and the anti-theft device body 1 turns on the switch SW3. The ECU is energized (step 6 (S6)).
[0042]
In this state, the user, that is, the rider, starts the cell motor Ms (step 8 (S8)) by pressing the cell starter switch SW4 which is the switch SW4 near the grip of the handle Hn (step 7 (S7)).
[0043]
Then, when the engine E is started (step 9 (S9)), the pressing of the switch SW4 may be stopped.
[0044]
On the other hand, if the input code is incorrect in step 5 (S5), the process proceeds to step 10 (S10), and the number of input errors of the code is added by one.
[0045]
Next, the process proceeds from step 10 (S10) to step 11 (S11), and it is checked whether or not the number of input mistakes of the security code is more than 5 (step 11 (S11)).
Here, if the input mistake is less than 5 times, the process returns to the step 3 (S3) and the password is again input from the beginning.
[0046]
Thus, if the input error is within 5 times, the control and operation in the routine of Step 3 (S3) to Step 11 (S11) are repeated.
[0047]
On the other hand, if the number of input mistakes exceeds 5, that is, 6 times, the process proceeds from step 11 (S11) to step 12 (S12), and the antitheft device body 1 turns on the switch SW2, The alarm 5 is activated. Therefore, when the alarm device 5 is an alarm buzzer, the alarm buzzer of the motorcycle starts to sound and alerts people around.
For this reason, it becomes an alarm device when a motorcycle is about to be used illegally.
Further, even when the alarm device 5 is a hazard lamp, a passing lamp, or the like, it is an alarm device in the same manner that causes the attention of a person in the vicinity or a dog and tries to use it illegally. Of course, an alarm buzzer and a hazard lamp (or a passing lamp) may be combined as the alarm device 5. In such a case, an alarm is generated by sound and light, and the alarm device is more effective at night.
[0048]
Various methods for stopping the operation of the alarm device 5 in step 12 are conceivable. For example, as shown in FIG. 3, the alarm device 5 is operated for a predetermined time, specifically about 30 minutes ( Step 13 (S13)) may be used to prevent unauthorized persons from approaching again, or the alarm is stopped by removing the key inserted into the switch SW1. May be.
Alternatively, an alarm stop switch may be separately provided at a position where it is difficult to see.
[0049]
In the case of this embodiment, the display device 4 is configured to detect the start of the engine and automatically switch to the trip meter after the engine is started in step 9 (S9). Of course, instead of the trip meter, it may be configured to switch to another meter (for example, engine speed or speed).
[0050]
According to the anti-theft device configured as described above, it is not necessary to hold a card for transmitting a bulky password code or a large key in which an IC chip is embedded. Moreover, the present invention can be applied to a vehicle having a small instrument panel area such as a motorcycle. In addition, since the number of buttons is small, even if each button is a waterproof button, it can be implemented at low cost. Of course, each button may be configured with a touch panel.
[0051]
In the above-described embodiment, the case where the anti-theft device is mounted on a motorcycle has been described. Of course, it can also be applied to marine vehicle vehicles such as boats.
(Embodiment 2)
Next, an anti-theft device according to another embodiment of the present invention will be described. Basically, it is the same as the anti-theft device and has basically the same configuration as the block diagram shown in FIG. 1, but in the case of the anti-theft device As according to the second embodiment, Internally, in the form of a program (software), a setting function for turning on / off (valid / invalid) the function of the anti-theft device, a timer function for setting a time for turning off the function of the anti-theft device, and the theft The anti-theft device has a higher function in that it has a security code changing function for changing the security code stored in the storage device of the protection device body 1. In this embodiment, since the timer function is provided, the antitheft device itself is provided with another power source Bt1 (battery or capacitor) (see the two-dot chain line in FIG. 1).
[0052]
That is, the operation is performed as shown in the flowchart showing the control contents of the antitheft device of FIG. If the same control portion as that of the first embodiment is omitted, the switch code SW3 and the ECU are turned on when the password code is correct as a result of collating the input password code with the password code stored in advance. To step 7 (S7). In step 7, it is possible to determine whether or not to change the password code stored in the storage device to a new password code.
[0053]
Here, when the password is changed, the password is changed by inputting a new password to be stored by the same method as the password input in the first embodiment (step 8 (S8)). ).
[0054]
In the case of “not changing the password” or when the change of the password is completed, it can be determined whether or not the anti-theft function is turned off (invalid) (step 9 (S9)).
[0055]
If the anti-theft function is not turned off, the process proceeds to step 14 (S14), and steps 14 to 16 (S16) are executed. That is, by turning on the switch SW4 of the cell motor Ms, the cell motor is started and the engine can be started.
[0056]
On the other hand, when the anti-theft function is turned off in the step 9, it is determined whether or not the “OFF” state is continued for a predetermined time, that is, whether or not the timer function is turned on ( Step 17 (S17)).
In step 17, when a timer is set, for example, when a timer is set for 10 minutes, in step 18 (S18) and step 19 (S19), the time is measured for the predetermined time (10 minutes). When the time has elapsed, the anti-theft function is turned on again, and the process proceeds to step 1. Therefore, for example, if the key is removed from the key switch at the gas station for refueling, the key is inserted into the key hole of the key switch without entering the password again within the predetermined time. Just start the engine. When the key is removed from the key hole of the key switch, the switch SW1 is turned off, but the power source Bt1 supplies power within a predetermined time.
[0057]
If the timer is not set in step 17, the anti-theft function continues to be turned off (step 21 (S21)). When this anti-theft function is turned off, even if the key is removed from the keyhole in this state and the switch SW1 is turned off, the next time only the switch SW1 is turned on by inserting and rotating the key into the keyhole. Thus, the switch SW3 and the ECU are operated. In order to cancel the off state of the anti-theft function, the anti-theft function is set to ON in step 9 or the anti-theft function is turned off in step 9 and a timer is set in step 17.
[0058]
In the case of the anti-theft device according to the second embodiment configured as described above, it is freed from the troublesomeness of inputting a password code each time when refueling. In addition, when the vehicle is stored in a garage of a house or the like, the vehicle can be used in the same manner as a vehicle without the anti-theft device by turning off the anti-theft function. That is, even when an anti-theft device is required, it can be selectively used.
(Embodiment 3)
Next, an anti-theft device according to another embodiment of the present invention will be described. In the first embodiment or the second embodiment, an instrument panel Pi as shown in FIG. 5 may be used instead of the instrument panel shown in FIG. In the case of the instrument panel Pi shown in FIG. 5, the speedometer is configured to be displayed on a digital display device that can be switched to display of a code or the like, and is different in that it is more compact. The A button 2 is composed of one button, and is configured such that each time it is pressed, the numerical value increases (or decreases) one by one.
[0059]
In such a case, the instrument panel Pi can be arranged even in a narrower space.
Further, the instrument panel Pi shown in FIG. 5 is configured such that the solar power generation panel 20 can be arranged in a vacant space of the instrument panel Pi to compensate for the electricity consumed by the DC power source Bt. Yes.
[0060]
In the instrument panel Pi shown in FIG. 5, the same or corresponding components as those in the instrument panel shown in FIG. In FIG. 5, 18 is an oil warning light, and 19 is a fuel warning light.
(Embodiment 4)
In the antitheft device according to the present invention, the instrument panel Pi may be an instrument panel different from the instrument panel illustrated in FIGS. 2 and 5, that is, the instrument panel Pi as illustrated in FIG. 6. . In the case of the instrument panel Pi shown in FIG. 6, the A button 2 for inputting the code and the B button 3 for fixing the numerical value selected by the A button 2 are touch panel type. In such a case, the instrument panel Pi is simpler in structure and higher in waterproof performance. The A button 2 is composed of one button, and is configured such that each time it is pressed, the numerical value increases (or decreases) one by one.
[0061]
In the instrument panel shown in FIG. 6, the same or corresponding components as those in the instrument panel shown in FIG. 2 or FIG.
[0062]
By the way, in the above-described embodiment, the code is composed of a series of continuous codes. Instead of this, in other words, the concept of “region” is introduced instead of “digit”, and a specific region is set. A specific code may be input. In addition, when the concept of the area is introduced in this way, it is possible to specify the order in which the code is input in order from which area, and to make the combination of the secret codes more complicated. Of course, when the concept of “digit” is used for the personal identification code, it is possible to specify the order of digits to be input and to make it complicated in the same way. And if comprised in this way, the situation which can input a PIN code more accidentally can be reduced, and a theft prevention function can be improved.
[0063]
【The invention's effect】
According to the antitheft device according to the present invention, a vehicle can be used without carrying a card having a function of transmitting a personal identification code or a key embedded with an IC chip.
In addition, since the code can be input with the minimum two types of buttons, it can be easily applied to a vehicle having a margin in an instrument panel such as a motorcycle or a small planing boat.
[0064]
In addition, the anti-theft device has high anti-theft performance.
