Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an antitheft device for a motorcycle (referring to a concept including a motor-equipped bicycle and an automatic tricycle) and a motorcycle equipped with the antitheft device.
[0002]
[Prior art]
The motorcycle has a configuration in which the driver's seat is opened to the outside and 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 a motorcycle, the anti-theft performance is inferior 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]
In view of such circumstances, after turning on the main switch with a key that matches the key switch, the transmitter that is carried in the device on the vehicle side of the antitheft device that stores predetermined password data An anti-theft device capable of starting an engine is provided only when the same password data is transmitted from a card (see Patent Document 1).
[0005]
[Patent Document 1]
Japanese Patent No. 311585.
[0006]
As a known antitheft device, there is known a motorcycle in which an IC chip in which a password is stored is embedded in a key inserted into a main switch and the engine cannot be started with other keys. .
[0007]
[Problems to be solved by the invention]
However, the key switch can be turned on only by the anti-theft device using the transmitter (card) and the receiver for transmitting the former predetermined password data and the key in which the latter IC chip having the predetermined password data is embedded. In any of these anti-theft devices, the verification of the password data is started only after the key is inserted into the key switch. Therefore, a predetermined time after the key is inserted until the verification of the password data is completed. There is an inconvenience that the engine cannot be started.
[0008]
In addition, as another problem, in the case of any of the above portable antitheft devices, if the engine cannot be started, whether it is caused by a mismatch of password data, or essentially due to engine failure, There is an inconvenience that it cannot be judged.
[0009]
The present invention has been made in view of such a current situation, and can start the engine immediately when the key switch is turned on with a key without deteriorating the anti-theft performance. An object of the present invention is to provide a motorcycle antitheft device and a motorcycle equipped with the antitheft device so that a vehicle user can immediately determine whether the engine cannot be started due to a failure of the engine itself or a failure of the engine itself. And
[0010]
[Means for Solving the Problems]
The present invention can solve the above-mentioned problems by a motorcycle antitheft device having the following configuration. That is,
The anti-theft device for a motorcycle according to the present invention includes a transmitter that can wirelessly transmit personal identification data ( also referred to as a personal identification code in this specification) to a receiver, and a portable transmitter that is mounted on a vehicle. And a receiver for receiving the password data from the vehicle, and if the received password data is legitimate password data, the vehicle can be used, and a confirmation display means mounted on the vehicle. A control device, and the control device determines whether or not the password data sent from the transmitter is authentic, and if it is determined to be correct, the password data is correct. A theft prevention device for a motorcycle configured to control the signal indicating that the confirmation display means provided on the vehicle side to emit,
A second battery as a power source of the receiver, the control device and the confirmation display means is mounted on the vehicle separately from the first battery as a main power source of the motorcycle ,
Even when the engine does not start due to a cause other than the mismatch of the password data, the control device is supplied with power from the second battery, and the password data transmitted from the transmitter is normal. Sometimes, the result is displayed on the confirmation display means .
A motorcycle according to the present invention includes the anti-theft device as described above.
[0011]
Thus, according to the motorcycle antitheft device configured as described above, when the user (rider) holding the transmitter enters the predetermined distance range with respect to the motorcycle, the transmitter automatically The personal identification data is automatically transmitted to the receiver of the two-wheeled vehicle, the verification of the personal identification data is started in the control device of the antitheft device, and the verification of the personal identification data has already been completed when the key is inserted into the key switch. Therefore, when the key is inserted into the key switch and turned on, the engine can be started immediately.
In addition, when the password data is collated and the collation results match, the control device controls the confirmation display means to issue a signal that the password data received by the receiver is correct. For this reason, even when the engine does not start, whether the cause of the engine not starting is due to incorrect password data or whether the engine has failed or not, depending on whether or not the correct signal is issued. It can be easily judged whether it is a thing.
[0012]
Further, in the motorcycle antitheft device, if the confirmation display means is a motorcycle flasher, it can be easily seen by a user (rider) not only at night but also in the daytime. In addition, since the configuration (flasher) essential for the motorcycle is effectively used as the confirmation display means, the weight of the motorcycle is not increased and the number of parts is not increased.
[0013]
In the antitheft device of the motorcycle, the antitheft device further includes a theft sensor, and the theft sensor reacts even though the password data is incorrect or the password data is not received. In addition, if the alarm means is configured to operate, when the user does not intend to use the motorcycle and theft occurs, the alarm means (for example, a horn or a passing lamp) is activated, The theft can be prevented in advance.
[0014]
Furthermore, in the antitheft device for a motorcycle, when the antitheft sensor is a sensor that is disposed in a suspension portion of the vehicle and detects the expansion and contraction of the suspension, when the motorcycle is lifted by a crane or the like, the length of the suspension is increased. Since it changes (extends), theft can be detected. Of course, even when a person tries to move the motorcycle while being pushed by hand, the length of the suspension changes (shrinks) when the stand is removed, so that theft can be detected.
[0015]
Further, in the antitheft device for motorcycles, when the antitheft sensor is a sensor for detecting the operation of the speedometer of the motorcycle, the speedometer operates when attempting to move the motorcycle in a hand-held state. Therefore, it is possible to detect theft.
[0016]
Also, in the motorcycle antitheft device, if the alarm means is a horn arranged in the vehicle, a loud sound alerts the surrounding people, so if the rider is not in the vicinity There is also a preventive effect due to its loud sound. In the case of this embodiment, since the configuration essential for the motorcycle is effectively used as a part of the anti-theft device, the weight of the motorcycle is not increased and the number of parts is also increased. Don't be.

Thus, the antitheft device configured as described above operates as follows. Hereinafter, the operation of the antitheft device together with the control contents of the antitheft control program stored in the antitheft device main body 1 will be described with reference to FIG. 3 which is a flowchart of the control of the antitheft device. That is,
When a user (rider) of a motorcycle holds the transmitter 10 in a hand or a pocket and enters a predetermined range of the motorcycle, for example, within a range of 15 m, the transmitter 10 is wirelessly transmitted. Is received by the receiver 2 (motorcycle) (step 1 (S1)).
[0034]
Next, the received personal identification code is transmitted from the receiver 2 to the anti-theft device body 1 and is a regular personal code in light of the personal code stored in the anti-theft device body 1 in advance. Whether or not (Step 2 (S2)).
[0035]
When the collated password code is a regular password, that is, when the correct password is received, the confirmation display means 6 is turned on and the switch SW3 is turned on (step 3 (S3)). For this reason, the rider can confirm that the collation of the passwords is consistent since the confirmation display means 6 is ON (lighted state).
[0036]
Accordingly, when the rider inserts the key Ky into the key switch SW1 and rotates it to the “ON” position, the key switch SW1 is closed, and electricity is supplied to the electric wire Lm leading to the cell motor switch SW4. Accordingly, the rider can start the engine E immediately by operating the cell motor switch SW4 (step 4 (S4)) (step 5 (S5)). That is, the rider can start the engine E immediately without waiting for the time required for collation with the personal identification code to be wasted.
[0037]
If the engine E does not start even when the cell motor switch SW4 is operated, the confirmation display means 6 is turned on. For this reason, the engine or the like is not caused by the anti-theft device As. It can be seen that the engine E does not start due to the essential reason.
[0038]
On the other hand, if it is not a legitimate password in step 2 (S2), it is next checked whether or not the theft sensor 5 is ON (step 6 (S6)). The prevention device main body 1 closes the switch SW2 and activates the alarm device 7 (step 7 (S7)).
[0039]
Therefore, the operation of the alarm device 7 prevents theft as much as possible.
[0040]
In Step 6 (S6), if the theft sensor 5 is OFF, the process proceeds to Step 8 to check whether or not a predetermined period of time has passed since the theft sensor 5 is OFF (Step 8 (S8)). S8)). Therefore, once a wrong password code is transmitted, the password is not received for a predetermined time. During this time, even if password codes having different contents are transmitted by trial and error, they are not received, and theft is prevented.
[0041]
Then, when a predetermined time has elapsed, the process returns to step 1 (S1) and waits in a state where the password can be received. Therefore, even if an incorrect password is received, after a predetermined time has passed, the system again stands by in a state where the password can be received.When the motorcycle rider enters the predetermined distance, the password is received, Perform a series of controls.
[0042]
On the other hand, when the predetermined time has not elapsed, the process returns to step 6 (S6) to check again whether or not the anti-theft sensor 5 is ON. That is, the routine goes through the routines of Step 6 to Step 8 within a predetermined time.
[0043]
By the way, even if the password is not input, it is checked whether or not the theft sensor 5 is ON (step 9 (S9)).
[0044]
In step 9 (S9), when the theft sensor 5 is turned on, the anti-theft device body 1 closes the switch SW2 and activates the alarm device 7 (step 10 (S10)).
[0045]
Accordingly, the theft state is always detected by the theft sensor 5, and when it is detected, anti-theft can be expected as much as possible by the operation of the alarm device 7.
[0046]
In the case of the anti-theft device As according to this embodiment, as described above, the second battery 3 is charged by the solar panel 4 at appropriate time intervals, and thus used without being consumed for a long period of time. can do.
Further, as described above, the battery built in the transmitter 10 is also configured to be charged when the key Ky is inserted into the key switch. .
(Embodiment 2)
By the way, as another embodiment, in the flowchart shown in FIG. 3, in step 2 (S2), when the password is not regular, that is, when “NO”, the control to return to step 1 is performed. Good. In such a case, the control step can be reduced, and when a proper password is transmitted from the user of the motorcycle immediately after receiving the wrong password, without waiting for a predetermined time, This is a preferred embodiment in that the processing of step 2 and step 3 can be performed.
[0047]
【The invention's effect】
According to the antitheft device for a motorcycle according to the present invention, the engine can be started immediately when the key switch is turned on with the key without lowering the antitheft performance by collating the password data.
[0048]
Moreover, when the engine of the motorcycle does not start, it can be immediately determined whether the engine cannot be started due to the mismatch of the password data or whether the engine cannot be started due to a failure of the engine itself.
[0049]
Further, by providing a theft sensor, a motorcycle antitheft device having higher anti-theft performance can be obtained.
