  Motorcycles are still established as major vehicles in emerging countries, especially in Southeast Asia. In recent years, even in motorcycles, there are some vehicles that do not have a steering lock mechanism due to the installation of a smart ECU (Electronic Control Unit) that can lock and unlock the steering of a motorcycle and start the engine without using a mechanical key. However, in many motorcycles, a steering lock mechanism using a mechanical key is still mounted on the vehicle. Since the steering lock mechanism is an external part, it is necessary to consider waterproofness, and it is necessary to use heavy mechanical parts in the structure, which increases the weight and causes a deterioration in fuel consumption. In addition, there are only about 1000 variations of mechanical keys in the key creation method, and the steering lock mechanism is laid out in a position where it can be seen from the outside, so there is concern about theft protection from the past. is there.

The flowchart which shows the control method at the time of steering lock locking in the antitheft system of 1st Example which concerns on this invention.

Embodiments according to the present invention will be described below with reference to the drawings.
<First Example>
With reference to FIG. 1 and FIG. 2, the antitheft system 100 in a present Example is demonstrated. The anti-theft system 100 is provided in the saddle riding type vehicle MC. The straddle-type vehicle MC is a so-called motorcycle such as a motorcycle or a scooter, and travels on a motorcycle such as a drive device ENG for driving itself such as an engine or a motor, and a steering STR that is a so-called steering wheel for steering. A device is provided.

  The straddle-type vehicle MC further includes a lockable storage space SPC. The storage space SPC is a so-called storage box that is disposed below the seating seat for the passenger and is configured to be opened and closed by the seating seat. The storage space SPC may be arranged below the steering STR and configured to be openable and closable with a lid. Items stored in the storage space SPC are, for example, belongings such as helmets and passenger's bags. The storage space SPC can be locked. For example, when the storage space SPC is disposed below the seating seat for the occupant, the seating seat that can be opened and closed is configured to be lockable. When the storage space SPC is locked, the seating seat cannot be opened. Further, when the storage space SPC is disposed below the steering STR, a lid that can be opened and closed is configured to be lockable. The configuration that the seating sheet and the lid are lockable means that the seating sheet and the lid have a mechanical key for firmly connecting the seating sheet and the lid to the main body.

  The straddle-type vehicle MC further includes a short-range wireless authentication device 20 that performs wireless communication with the portable device 10 that performs short-range wireless communication carried by the user and authenticates the portable device 10. The short-range wireless authentication device 20 includes an antenna 21 for performing short-range wireless communication with the portable device 10. Short-range wireless communication is wireless communication having a communication area of a distance of several centimeters to several tens of centimeters. For example, ISO / IEC 14443, ISO / IEC 18092, ISO / IEC 15693, etc. It is a compliant communication. Of course, the short-range wireless communication is not limited to the standards listed here, as long as it can perform wireless communication with a communication area ranging from several centimeters to several tens of centimeters. In addition, by using such a standard with a short communication distance, it is difficult to perform a relay attack or the like, and the anti-theft property is improved.

  The portable device 10 that performs short-range wireless communication carried by the user has a communication function corresponding to the communication performed by the short-range wireless authentication device 20. The portable device 10 may be a so-called FOB 10 having such a communication function and a function as a key of the saddle riding type vehicle MC, or may be the portable terminal 10 having a telephone function and the like. When the portable device 10 is the FOB 10, the FOB 10 is provided with a unique identification number corresponding to the short-range wireless authentication device 20 in advance, and transmits the identification number when approaching the short-range wireless authentication device 20. When the portable device 10 is the portable terminal 10, the portable terminal 10 sets a unique identification number corresponding to the short-range wireless authentication device 20 in advance and transmits the identification number when approaching the short-range wireless authentication device 20. To do. It is assumed that the short-range wireless authentication device 20 has successfully authenticated the portable device 10 when receiving the corresponding identification number.

  The short-range wireless authentication device 20 controls and locks a mechanical key for connecting the seating sheet and the lid to the main body. When authentication of the portable device 10 is successful, the short-range wireless authentication device 20 unlocks if the machine key is locked, and locks if the machine key is unlocked. That is, the short-range wireless authentication device 20 locks and unlocks the storage space SPC when the authentication of the portable device 10 is successful.

  The straddle-type vehicle MC further includes an operation unit 30 that enables or disables the drive device ENG and the steering STR. For example, the operation unit 30 of the drive device ENG is an ignition switch or an engine starter switch for starting and stopping the drive device ENG, and the operation unit 30 of the steering STR locks / unlocks (unlocks) the steering STR. This is a steering lock locking / unlocking switch. The steering lock locking / unlocking switch is linked to a mechanical part that mechanically prevents the rotation of the steering STR, and is locked by moving the mechanical part to a position that prevents the rotation of the steering STR, and does not prevent it from being reversed. Move to to unlock.

  The operation unit 30 is exposed in the lockable storage space SPC and can be operated only via the storage space SPC. Therefore, the occupant cannot operate the operation unit 30 until the storage space SPC is unlocked and opened. For example, when the storage space SPC as shown in FIG. 2 is arranged below the seating seat, when the occupant who is going to get on the seat presses the open switch OSW of the seating seat, the portable device 10 carried by the occupant is The antenna 21 of the distance wireless authentication device 20 is within the communication area of short-range wireless communication or is held over the antenna 21. Then, since the short-range wireless authentication device 20 unlocks the seating seat, the occupant opens the seating seat and operates the steering lock locking / unlocking switch and the ignition switch / engine starter which are the operation unit 30 to operate the steering. The unlocking operation of the STR and the driving device ENG can be started.

  As described above, a theft prevention system including the portable device 10 that is carried by a user and performs short-range wireless communication, and the short-range wireless authentication device 20 that performs wireless communication with the portable device 10 and authenticates the portable device 10. 100 has an anti-theft function by increasing the difficulty of the approach to the operation unit 30 by arranging the operation unit 30 having an important function for crime prevention such as a steering lock function in the lockable storage space SPC. Can be improved.

  In addition, since the steering lock is usually an appearance part, it is necessary to consider waterproofness, and it is necessary to use a mechanical part that is heavy in structure. However, since the operation unit 30 is installed in the storage space SPC, the steering lock is waterproof. Therefore, it is possible to improve the anti-theft property while reducing the vehicle weight and cost. Further, since the operation unit 30 is exposed in the storage space SPC, it is not necessary to consider the leakage of the switch due to water intrusion or foreign matter, so that the current to be supplied to the switch can be reduced. It is possible to simplify the structure and reduce the weight and cost of the harness associated with the switch.

  Moreover, it is preferable that the short-range wireless authentication device 20 has a structure incapable of wireless communication with an object stored in the storage space SPC. For example, as shown in FIG. 1, the structure incapable of wireless communication with an object stored in the storage space SPC is a communication distance A that enables short-range wireless communication even at the closest location in the storage space SPC from the antenna 21. This is a structure separated from the above. Also, a ferrite sheet or the like that does not allow electromagnetic waves to pass through is disposed between the antenna 21 and the storage space SPC so that communication is not performed between the portable device 10 and the antenna 21 in the storage space SPC. Good.

  With such a structure, even if the portable device 10 is left in the storage space SPC, the portable device 10 does not enter a communication area where short-range wireless communication is possible. Then, since the portable device 10 and the short-range wireless authentication device 20 do not communicate with each other, the short-range wireless authentication device 20 does not succeed in authentication and locks the storage space SPC. According to this, the anti-theft system 100 can prevent the portable device 10 from being locked while being placed in the storage space SPC.

  With reference to FIG. 3, the control method at the time of the steering lock unlocking in the anti-theft system 100 is demonstrated. In the flowchart, S means a step. Moreover, the step shown with the dotted line shows a passenger | crew's action, and the short-distance radio | wireless authentication apparatus 20 is described with NFC ECU.

  When the open switch OSW or the like of the seating seat is pressed, the short-range wireless authentication device 20 (NFC ECU) of the anti-theft system 100 transmits a response request signal together with its own identification number to the portable device 10 in S100, and in S102 Waiting for reception of a response signal from the portable device 10. Before that, the portable device 10 is held over the short-range wireless authentication device 20 in S200, and in S202, it is checked whether or not a response request signal from the short-range wireless authentication device 20 is received. When the response request signal is received, the portable device 10 checks the identification number included in the received response request signal in S204. If the identification number is the identification number of the corresponding short-distance wireless authentication device 20, the portable device 10 transmits a response signal together with its own identification number to the short-range wireless authentication device 20 in S206.

  When the short-range wireless authentication device 20 receives a response signal from the portable device 10, the short-range wireless authentication device 20 checks the identification number of the portable device 10 in S104. When the identification number is the identification number of the corresponding portable device 10, the short-range wireless authentication device 20 can unlock the storage box that is the storage space SPC and open the seating seat in S106. To. In this state, the occupant opens the storage box in S108 and operates the operation unit 30 that locks the steering STR in S110 to perform the operation of unlocking the steering STR.

  Thereafter, in S112, the occupant closes the seat and closes the storage box. Then, the short-range wireless authentication device 20 transmits a response request signal together with its own identification number to the portable device 10 in S114, and waits for reception of a response signal from the portable device 10 in S116. As described above, the portable device 10 performs S202 to S206, and transmits a response signal together with its own identification number to the short-range wireless authentication device 20.

  When the short-range wireless authentication device 20 receives a response signal from the portable device 10, the short-range wireless authentication device 20 checks the identification number of the portable device 10 in S118. If the identification number is the identification number of the corresponding portable device 10, the short-range wireless authentication device 20 releases the lock of the steering STR in S120, and the steering STR is rotatable and is ready for driving.

  With reference to FIG. 4, the control method at the time of steering lock locking in the anti-theft system 100 is demonstrated. The short-range wireless authentication device 20 (NFC ECU) of the anti-theft system 100 continues to check whether or not the drive device ENG stops in S300. When the driving device ENG stops, the short-range wireless authentication device 20 transmits a response request signal together with its own identification number to the portable device 10 in S302, and waits for reception of a response signal from the portable device 10 in S304.

  Before that, the portable device 10 exists in the communication area for short-range wireless communication such as being held over the short-range wireless authentication device 20 in S400, and receives a response request signal from the short-range wireless authentication device 20 in S402. Inspect whether or not to do. When the response request signal is received, the portable device 10 checks the identification number included in the received response request signal in S404. When the identification number is the identification number of the corresponding short-range wireless authentication device 20, the portable device 10 transmits a response signal together with its own identification number to the short-range wireless authentication device 20 in S406.

  When the short-range wireless authentication device 20 receives a response signal from the portable device 10, the short-range wireless authentication device 20 checks the identification number of the portable device 10 in S306. When the identification number is the identification number of the corresponding portable device 10, the short-range wireless authentication device 20 can unlock the storage box that is the storage space SPC and open the seating seat in S308. To. In this state, the occupant opens the storage box in S310 and operates the operation unit 30 in S312 to perform the operation of locking the steering STR.

  Thereafter, in S314, the occupant closes the seat and closes the storage box. Then, the short-range wireless authentication device 20 transmits a response request signal together with its own identification number to the portable device 10 in S316, and waits for reception of a response signal from the portable device 10 in S318. As described above, the portable device 10 performs S402 to S406, and transmits a response signal together with its own identification number to the short-range wireless authentication device 20.

  When the short-range wireless authentication device 20 receives a response signal from the portable device 10, the short-range wireless authentication device 20 checks the identification number of the portable device 10 in S320. If the identification number is the identification number of the corresponding portable device 10, the short-range wireless authentication device 20 locks the steering STR in S322, and the steering STR cannot be rotated.

  As described above, in the anti-theft system 100, the operation unit 30 having an important function for crime prevention such as a steering lock function is disposed in the lockable storage space SPC, and the difficulty of the approaching method to the operation unit 30 is increased.
