Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an anti-theft device for a motorcycle (also referred to as a concept including a motorbike and a motorcycle).
[0002]
[Prior art]
The motorcycle has a form in which a driver's seat is opened to the outside so that anyone can get into the driver's seat.
In addition, the so-called key switch is arranged in a portion generally exposed to the outside such as an instrument panel near the driver's seat, specifically, in front of the driver's seat.
[0003]
Therefore, in the case of a motorcycle, the antitheft performance is inferior to that of a four-wheeled vehicle having a configuration in which a driver's seat is isolated from the outside and a user (driver) cannot enter.
[0004]
In view of such a situation, after the main switch is turned on with a key that matches the key switch, the transmitter carried by the vehicle-side device of the anti-theft device that further stores predetermined password data There is provided an anti-theft device that enables the engine to be started only when the same personal identification data is transmitted from a (card) (see Patent Document 1).
[0005]
[Patent Document 1] Japanese Patent No. 3112585.
[0006]
Further, as a known anti-theft device, there is known a motorcycle in which an IC chip storing a personal identification code is embedded in a key inserted into a main switch, and an 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 a transmitter (card) for transmitting the predetermined password data and a receiver, and a key in which an IC chip having the predetermined password data is embedded. In any of these anti-theft devices, the collation of the security data is started only after the key is inserted into the key switch, so that the security data is collated for a predetermined time after the key insertion. There is a disadvantage that the engine cannot be started.
[0008]
Further, as another problem, in any of the portable anti-theft devices, if the engine cannot be started, whether the cause is a mismatch of the password data, or whether it is essentially due to a failure of the engine, There is a disadvantage that it cannot be determined.
[0009]
The present invention has been made in view of such a situation, and the engine can be started immediately when the key switch is turned on with a key without deteriorating the anti-theft performance. It is an object of the present invention to provide a motorcycle anti-theft device that allows a vehicle user to immediately determine whether the vehicle cannot be started or whether the engine itself cannot be started due to a failure of the engine itself.
[0010]
[Means for Solving the Problems]
The present invention can solve the above-mentioned problem by a motorcycle anti-theft device having the following configuration. That is,
A motorcycle anti-theft device according to the present invention includes a portable transmitter that wirelessly transmits personal identification data, and a receiver that is mounted on a vehicle and receives personal identification data from the transmitter. In the motorcycle anti-theft device that enables the use of the vehicle if is the correct password data,
The anti-theft device further includes a confirmation display unit and a control device mounted on the vehicle,
The transmitter is configured to automatically transmit password data when within a predetermined distance range with respect to the receiver,
The control device determines whether or not the password data transmitted from the transmitter is valid, and when determining that the password data is valid, a signal indicating that the password data is valid, It is characterized in that the confirmation display means provided on the vehicle side controls to emit.
[0011]
According to the motorcycle anti-theft device configured as described above, when the user (rider) holding the transmitter enters a predetermined distance range with respect to the motorcycle, the transmitter automatically transmits the motorcycle. The password data is automatically transmitted to the receiver of the motorcycle, the collation of the password data is started in the control device of the antitheft device, and the collation of the password 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 unit controls the confirmation display means to generate a signal indicating 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 erroneous password data or to a failure of the engine itself, etc., depending on whether or not the signal indicating that the engine was correct was issued. That is, it can be easily determined.
[0012]
In the motorcycle anti-theft device, if the confirmation display means is a motorcycle flasher, it can be easily visually recognized by a user (rider) not only at night but also during the day. 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]
Further, in the motorcycle anti-theft device, the anti-theft device further includes a theft sensor, and when the password sensor is incorrect, or the password sensor does not receive the password data, the anti-theft sensor reacts. In addition, if it is configured to activate the alarm means, when the user does not intend to use the motorcycle, if the theft occurs, the alarm means (for example, a horn or a passing lamp) is activated, The theft can be prevented.
[0014]
Further, in the motorcycle anti-theft device, if the theft sensor is a sensor disposed on a suspension portion of the vehicle and detects expansion and contraction of the suspension, the length of the suspension is increased when the motorcycle is lifted by a crane or the like. The change (extension) makes it possible to detect theft. Of course, even when a person tries to move the motorcycle in a hand-pushed state, the length of the suspension changes (shrinks) when the stand is removed, so that theft can be detected.
[0015]
Further, in the motorcycle anti-theft device, if the theft sensor is a sensor that detects the operation of a speedometer of the motorcycle, the speedometer operates when the motorcycle is to be moved in a pushed state. Thus, theft can be detected.
[0016]
Further, in the motorcycle anti-theft device, when the alarm means is a horn arranged in the vehicle, a loud noise is used to alert the surrounding people, so if the rider is absent nearby, The loud noise also has a preventive effect. In the case of this embodiment, since the essential configuration of the motorcycle is effectively used as a part of the antitheft device, the weight of the motorcycle is not increased, and the number of parts can be increased. No.
[0017]

Thus, according to the anti-theft device configured as described above, the following operation is performed. Hereinafter, the operation of the anti-theft device together with the control content of the anti-theft control program stored in the anti-theft device main body 1 will be described with reference to FIG. 3 which is a flowchart of the control of the anti-theft device. That is,
When a user (rider) of the motorcycle holds the transmitter 10 in a hand or a pocket or the like and enters a predetermined range of the motorcycle, for example, a range of 15 m or less, the transmitter 10 wirelessly transmits. The received security code is received by the receiver 2 (motorcycle) (step 1 (S1)).
[0034]
Next, the received security code is transmitted from the receiver 2 to the anti-theft device main body 1, and is a proper security code in light of a pre-stored security code in the anti-theft device main body 1. Is checked. (Step 2 (S2)).
[0035]
If the collated code is a proper code, that is, if a correct code 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 personal identification code matches because the confirmation display means 6 is ON (lit).
[0036]
Therefore, when the rider inserts the key Ky into the key switch SW1 and rotates it to the “ON” position, the key switch SW1 closes, and electricity is supplied to the electric wire Lm leading to the self-motor switch SW4. Therefore, the rider can immediately start the engine E by operating the starter switch SW4 (step 4 (S4)) (step 5 (S5)). That is, the rider can immediately start the engine E without wasting time waiting for collation of the personal identification code as in the related art.
[0037]
If the engine E does not start even if the starter switch SW4 is operated, the confirmation display means 6 is ON, and the reason is not due to the anti-theft device As, that is, the engine or the like. It is found that the engine E does not start due to the essential reason of the above.
[0038]
On the other hand, if it is determined in step 2 (S2) that the password is not a legitimate password, then it is 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 7 (step 7 (S7)).
[0039]
Therefore, the operation of the alarm 7 prevents theft as much as possible.
[0040]
If the theft sensor 5 is OFF in step 6 (S6), the process proceeds to step 8 to check whether the OFF state of the theft sensor 5 has elapsed for a predetermined time (step 8 (step 8)). S8)). Therefore, once an incorrect security code is transmitted, the security code is not received for a predetermined time. During this time, even if a security code having a different content is transmitted by trial and error, the security code is not received, and theft is prevented.
[0041]
Then, after the elapse of the predetermined time, the process returns to step 1 (S1), and waits in a state where the password can be received. Therefore, even if an incorrect security code is received, after a predetermined time has elapsed, the vehicle waits again in a state in which the security code can be received, and when the motorcycle rider is within a predetermined distance, the security code is received, and the above-described security code is received. Performs a series of controls.
[0042]
On the other hand, if the predetermined time has not elapsed, the process returns to step 6 (S6), and it is checked again whether the anti-theft sensor 5 is ON. That is, during the predetermined time, the routine of steps 6 to 8 is performed.
[0043]
By the way, it is checked whether or not the theft sensor 5 is ON even when the password is not input (step 9 (S9)).
[0044]
Then, when the theft sensor 5 is turned on in step 9 (S9), the antitheft device main body 1 closes the switch SW2 and activates the alarm 7 (step 10 (S10)).
[0045]
Therefore, the theft sensor 5 always detects the theft state, and when it is detected, the alarm 7 operates to prevent theft as much as possible.
[0046]
Further, in the case of the anti-theft device As according to this embodiment, as described above, since the second battery 3 is charged at appropriate time intervals by the solar panel 4, it can be used without being consumed for a long period of time. can do.
Also, as described above, the battery built in the transmitter 10 is configured to be charged when the key Ky is inserted into the key switch, so that the battery is not consumed for a long time. .
(Embodiment 2)
By the way, as another embodiment, in the flowchart shown in FIG. 3, in step 2 (S2), when the personal identification code is not a proper one, that is, when "NO", a control to return to step 1 may be performed. Good. In such a case, the number of control steps can be reduced, and immediately after receiving an incorrect PIN code, if a regular PIN code is transmitted from the user of the motorcycle, 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 motorcycle anti-theft apparatus of the present invention, the engine can be started immediately after the key switch is turned ON without lowering the anti-theft performance by collating the password data.
[0048]
In addition, when the engine of the motorcycle does not start, it is possible to immediately determine 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 further providing a theft sensor, a motorcycle anti-theft device having higher anti-theft performance can be obtained.
