Description

The present invention relates to a straddle-type vehicle operation permission device.
Priority is claimed on Japanese Patent Application No. 2017-152586 filed on Aug. 07, 2017, the content of which is incorporated herein by reference.

  BACKGROUND ART Conventionally, an electronic key system including an electronic key carried by a user and a control device (an in-vehicle device) mounted on a motorcycle such as a scooter has been known (for example, see Patent Document 1).

  Further, a vehicle door lock control system including a portable device and a control device mounted on a vehicle is known (for example, see Patent Document 2). In the vehicle door lock control system described in Patent Literature 2, the transmitting antenna and the receiving antenna are configured such that the directivity of the transmitting antenna and the directivity of the receiving antenna of the vehicle are different. When the request signal transmitted from the vehicle is received by the portable device, an answerback signal to which the reception intensity of the request signal is added as the portable device-side reception intensity is transmitted from the portable device. When the answerback signal is received by the vehicle, the reception strength of the received answerback signal is determined as the vehicle-side reception strength. When the vehicle-side reception intensity is equal to or higher than the first predetermined level, the door is controlled to the unlocked state. On the other hand, when the vehicle-side reception intensity is lower than the first predetermined level, the portable-device-side reception intensity added to the answerback signal is determined. The door is controlled to be in the unlocked state also when the portable device-side reception intensity is equal to or higher than the second predetermined level. That is, even if the reception strength of the answerback signal is low, if the reception strength of the request signal measured by the portable device is equal to or higher than a predetermined value, the door is controlled to the unlocked state (that is, the door is unlocked. ).

  Further, a vehicle remote control device including a portable terminal and an in-vehicle control device mounted on a vehicle is known (for example, see Patent Document 3). In the vehicle remote control device described in Patent Literature 3, the in-vehicle control device includes a reception intensity detection unit, a reception intensity comparison unit, and a device control unit. The reception intensity detector detects the reception intensity of the operation signal. The reception intensity comparison unit compares the reception intensity with a predetermined value. The device control unit prohibits the operation of the predetermined device of the vehicle (for example, the closing operation of the slide door) when the reception intensity is equal to or less than the predetermined value in the comparison result by the reception intensity comparison unit.

  Further, an electronic key system including an electronic key and an in-vehicle device is known (for example, see Patent Document 4). In the electronic key system described in Patent Literature 4, unlocking of a vehicle door or opening operation of a slide door having high security importance can be remotely controlled in a first remote controllable area. Locking of vehicle doors or starting the engine, which is of less security importance, is remotely controllable in a second remotely controllable area that is larger than the first remotely controllable area. When the reception intensity of the request signal transmitted from the electronic key and received by the on-vehicle device is equal to or less than the threshold, the locking of the vehicle door or the start of the engine can be remotely controlled, and the unlocking of the vehicle door or the opening operation of the slide door can be remotely controlled. I can't control it.

  However, as described above, in the inventions described in Patent Literature 1 to Patent Literature 4, the positional relationship between the operation unit and the communication device in the vehicle is not considered, and the operation may not be appropriately permitted in some cases. .

  An aspect according to the present invention has been made in view of such circumstances, and an object thereof is to provide a straddle-type vehicle operation permission device that can appropriately permit operation of a plurality of controlled objects. I do.

In order to solve the above problems, the present invention has adopted the following configurations.
(1) An operation permitting device for a saddle-ride type vehicle according to one aspect of the present invention includes an in-vehicle device mounted on the straddle-type vehicle, and a portable device, wherein the in-vehicle device operates the first control target. A first operation unit that receives a requested operation; a second operation unit that is arranged at a position different from the first operation unit and receives an operation that requests an operation of a second control target; and the first operation unit or the first operation unit. (2) The vehicle-mounted device includes a vehicle-mounted device-side transmitting unit that transmits a request signal when the operation unit receives an operation, a vehicle-mounted device-side receiving unit, and a control unit. The distance between the antenna and the second operation unit is equal to or greater than the distance between the transmission antenna and the first operation unit, and the portable device is a portable device-side receiving unit that receives the request signal; A reception intensity detection unit for detecting reception intensity; A portable device-side transmission unit that transmits an answer signal to an EST signal, wherein the portable device includes information indicating the reception strength of the request signal in the answer signal, and the control unit includes a first operation unit. If an operation is received, and if the in-vehicle device-side receiving unit receives the answer signal, and if the reception intensity of the request signal detected by the reception intensity detection unit is equal to or greater than a first threshold, The control unit permits the operation of the first control target, and the control unit, when the second operation unit receives the operation, and when the in-vehicle device-side reception unit receives the answer signal, the reception intensity detection unit The operation of the second control target is permitted even if the reception strength of the request signal detected by the control unit is less than the first threshold.

  According to the aspect of (1), the distance between the transmitting antenna and the second operating unit is equal to or greater than the distance between the transmitting antenna and the first operating unit, and the control unit determines that the reception intensity of the request signal is equal to or greater than the first threshold. In this case, the operation of the first control target is permitted, and the operation of the second control target is permitted even if the reception intensity of the request signal is less than the first threshold. Therefore, the transmission output when the transmission antenna transmits a signal necessary for permitting the operation of the first control target and the transmission output when the transmission antenna transmits a signal necessary for permitting the operation of the second control target are different. There is no need to make it different. As a result, the vehicle-mounted device has a different transmission output when transmitting a signal necessary for permitting operation of the first control target and a transmission output when transmitting a signal necessary for permitting operation of the second control target. The configuration of the side transmission unit can be simplified. That is, the operation of the first control target and the operation of the second control target can be appropriately permitted.

(2) An operation permission device for a saddle-ride type vehicle according to one aspect of the present invention includes an in-vehicle device mounted on the straddle-type vehicle, and a portable device, wherein the in-vehicle device operates the first control target. A first operation unit that receives a requested operation; a second operation unit that is arranged at a position different from the first operation unit and receives an operation that requests an operation of a second control target; and the first operation unit or the first operation unit. (2) An on-vehicle unit-side transmitting unit that transmits a request signal when the operation unit receives an operation, an on-vehicle unit-side receiving unit, and a control unit. The on-vehicle unit-side receiving unit includes a receiving antenna, The distance between the antenna and the second operation unit is equal to or greater than the distance between the reception antenna and the first operation unit, and the portable device is a portable device-side receiving unit that receives the request signal; Transmitter for transmitting the answer signal The vehicle-mounted device further includes a reception intensity detection unit that detects the reception intensity of the answer signal, and the control unit, when the first operation unit receives an operation, and the vehicle-mounted device-side reception unit When the answer signal is received, and when the reception intensity of the answer signal detected by the reception intensity detection unit is equal to or greater than a second threshold, the operation of the first control target is permitted, and the control unit When the second operation unit receives an operation, and when the in-vehicle device-side reception unit receives the answer signal, the reception intensity of the answer signal detected by the reception intensity detection unit is equal to the second intensity. Even if it is less than the threshold, the operation of the second control target is permitted.

  According to the aspect of (2), the distance between the receiving antenna and the second operating unit is equal to or longer than the distance between the receiving antenna and the first operating unit, and the control unit determines that the reception strength of the answer signal is the second. If the threshold value is equal to or greater than two thresholds, the operation of the first control target is permitted, and the operation of the second control target is permitted even if the reception intensity of the answer signal is less than the second threshold value. Therefore, the transmission output when the portable unit-side transmitting unit transmits a signal necessary for permitting the operation of the first control target, and the portable unit-side transmitting unit transmits a signal necessary for permitting the operation of the second control target. It is not necessary to make the transmission output different from the case. As a result, the portable device is different from the transmission output when transmitting the signal necessary for permitting the operation of the first control target and the transmission output when transmitting the signal necessary for permitting the operation of the second control target. The configuration of the side transmission unit can be simplified. That is, the operation of the first control target and the operation of the second control target can be appropriately permitted.

  In the case of the above (3), the operation of the second control target can be prohibited when the reception intensity of the request signal detected by the reception intensity detection unit is low.

(4) In the aspect of (2) above, the control unit may be configured to: when the second operation unit receives an operation; and when the in-vehicle device-side receiving unit receives the answer signal; The operation of the second control target may be permitted when the reception intensity of the answer signal detected by the detection unit is equal to or greater than a fourth threshold smaller than the second threshold.

  In the case of (4) above, when the reception intensity of the answer signal detected by the reception intensity detection unit is low, the operation of the second control target can be prohibited.

  Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

<First embodiment>
FIG. 1 is a configuration diagram illustrating an example of a straddle-type vehicle operation permission device 1 according to the first embodiment. The straddle-type vehicle operation permission device 1 includes an in-vehicle device 100 and a portable device 200. The on-vehicle device 100 is mounted on a straddle-type vehicle such as a scooter. The portable device 200 is carried by the user when the user uses a straddle-type vehicle. The on-vehicle device 100 includes a handle lock unit 110, a storage box locking unit 120, a control unit 130, a battery 140, and a relay 150.

  The handle lock 110 is configured similarly to the lock mechanism described in, for example, JP-A-2015-68131. The handle lock unit 110 switches between a locked state and an unlocked state of a handle (not shown) of the saddle type vehicle. The handle lock unit 110 includes a solenoid 111 as a first control target, and a first operation unit 112. The solenoid 111 has the same configuration as the solenoid described in, for example, JP-A-2015-68131. In the locked state of the handle, power is not supplied to the solenoid 111, and in the unlocked state of the handle, power is supplied to the solenoid 111. The first operation unit 112 is configured, for example, in the same manner as an ignition knob described in JP-A-2015-68131, and has at least an ON position and an OFF position. The first operation unit 112 accepts a user operation requesting energization of the solenoid 111 (that is, release of a lock pin that allows the ignition knob to rotate to release the lock of the handle). When the user arranges the first operation unit 112 at the ON position, when a condition described later is satisfied, the solenoid 111 is energized, and the locked state of the handle can be released.

  The storage box locking section 120 switches between a locked state and an unlocked state of the storage box B1 (see FIG. 4) disposed at the rear end (the rear side of the seat) of the saddle type vehicle. The storage box locking unit 120 includes an actuator 121 as a second control target and a second operation unit 122. The actuator 121 has a motor and a damping mechanism (both not shown), is connected to a lock provided in the storage box B1 by a driving force transmitting rod or wire, and the like. It is possible to switch between the locked state. The second operation unit 122 is configured by a push switch, and is arranged on a surface on the vehicle rear end side of the storage box B1 (see FIG. 4). The second operation unit 122 receives a user operation requesting the operation of the actuator 121 (that is, the unlocking of the storage box B1). When the user operates the second operation unit 122, the actuator 121 is activated and the locked state of the storage box B1 is released when a condition described later is satisfied.

  The control unit 130 is disposed substantially at the center of the vehicle, specifically, inside the seat below, and is electrically connected to the first operation unit 112, the second operation unit 122, the battery 140, and the actuator 121. And the actuator 121 are controlled. The control unit 130 includes a power supply circuit 131, a solenoid drive circuit 132, an actuator drive circuit 133, an input circuit 134, a control unit 135, a transmission unit 136, and a reception unit 137. The power supply circuit 131 generates output power required in the control unit 135 and the like from input power input from the battery 140 via the relay 150. The solenoid drive circuit 132 supplies a drive current to the solenoid 111 based on a control signal from the control unit 135. The actuator drive circuit 133 supplies a drive current to the actuator 121 based on a control signal from the control unit 135. When the first operation unit 112 receives a user operation requesting energization of the solenoid 111 (that is, unlocking of the steering wheel), the input circuit 134 inputs a signal indicating that to the control unit 135. When the second operation unit 122 receives a user operation requesting the operation of the actuator 121 (that is, unlocking of the storage box B1), the input circuit 134 inputs a signal indicating that to the control unit 135. .

  The control unit 135 includes an encryption processing unit 135A and a reception strength determination unit 135B. Part or all of the encryption processing unit 135A and the reception strength determination unit 135B are software function units that function when a processor such as a CPU (Central Processing Unit) executes a program. Some or all of these may be hardware function units such as LSI (Large Scale Integration) and ASIC (Application Specific Integrated Circuit).

  The encryption processing unit 135A performs a process of decoding the signal received by the reception unit 137, and checks whether the signal received by the reception unit 137 is a signal transmitted from the portable device 200. The reception intensity determination unit 135B determines whether or not the reception intensity of a signal (specifically, a request signal described later) transmitted from the vehicle-mounted device 100 and received by the portable device 200 is equal to or greater than a first threshold.

  The transmission unit 136 transmits a request signal. The request signal refers to a case where the first operation unit 112 receives a user operation requesting energization of the solenoid 111 (that is, unlocking of the handle), or a case where the second operation unit 122 operates the actuator 121 (that is, This signal is transmitted by the transmission unit 136 when a user operation requesting to unlock the storage box B1) is received. The transmission section 136 includes a drive circuit 136A and a transmission antenna 136B. The drive circuit 136A supplies a drive current for transmitting a request signal to the transmission antenna 136B based on a control signal from the control unit 135. The transmission antenna 136B transmits a request signal by radiating radio waves.

  The receiving unit 137 receives an answer signal. The answer signal is a signal transmitted by the portable device 200 when the portable device 200 receives the request signal and satisfies a condition described later. The receiving unit 137 includes a receiving antenna 137B and a receiving circuit 137A. The receiving antenna 137B captures the radio wave transmitted by the portable device 200. The receiving circuit 137A obtains an answer signal from the radio wave captured by the receiving antenna 137B.

The connection between each circuit inside the control unit 130 and each component outside the control unit 130 will be described. First, the relay 150 of the battery 140 is connected to the power supply circuit 131.
The power supply circuit 131 is connected to one end of the solenoid 111. The other end of the solenoid 111 is connected to a solenoid drive circuit 132. The input circuit 134 is connected to one end of the first operation unit 112. The other end of the first operation unit 112 is grounded. The input circuit 134 is connected to one end of the second operation unit 122. The other end of the second operation unit 122 is grounded. The actuator drive circuit 133 is connected to the actuator 121. The control unit 130 is grounded.

  The portable device 200 includes, for example, a power supply unit 210, a reception unit 220, a control unit 230, and a transmission unit 240. The power supply unit 210 supplies necessary power to the control unit 230 and the like. The receiving unit 220 receives the request signal transmitted by the on-vehicle device 100. The receiving unit 220 includes a receiving antenna 221. The receiving antenna 221 captures a radio wave transmitted by the vehicle-mounted device 100.

  The control unit 230 includes an encryption processing unit 231 and a reception strength detection unit 232. Some or all of the encryption processing unit 231 and the reception intensity detection unit 232 are software function units that function when a processor such as a CPU executes a program. Some or all of them may be hardware function units such as an LSI and an ASIC.

  The encryption processing unit 231 performs a process of decrypting the signal received by the reception unit 220, and checks whether the signal received by the reception unit 220 is a signal transmitted from the vehicle-mounted device 100. The reception intensity detection unit 232 detects (measures) the reception intensity of the request signal transmitted from the vehicle-mounted device 100 and received by the reception unit 220.

  The transmitting section 240 transmits an answer signal to the request signal. The transmission section 240 includes a transmission antenna 241 and a transmission IC (Integrated Circuit) 242. The transmission IC 242 supplies a drive current for transmitting an answer signal to the transmission antenna 241 based on a control signal from the control unit 230. The transmission antenna 241 transmits an answer signal by radiating radio waves. When transmitting section 240 transmits the answer signal, control section 230 includes information indicating the reception strength of the request signal in the answer signal.

  FIG. 2 is a diagram for explaining the reception strength of the request signal. More specifically, FIG. 2 shows the reception electric field strength of a signal (for example, a request signal) transmitted from the transmission antenna 136B when the transmission antenna 136B of the vehicle-mounted device 100 is arranged at the center position of the straddle-type vehicle B. It is a figure showing distribution of RSSI (Received Signal Strength Indicator). As shown in FIG. 2, the received field strength RSSI of the signal transmitted from the transmission antenna 136B decreases as the distance from the transmission antenna 136B increases. Therefore, as the distance between the transmission antenna 136B of the on-vehicle device 100 transmitting the request signal and the portable device 200 increases, the reception intensity of the request signal received by the receiving unit 220 of the portable device 200 decreases.

  FIG. 3 is a diagram for explaining a requirement that the in-vehicle device 100 be mounted on the straddle-type vehicle B. In FIG. 3, AR1 indicates an area where the distance from the straddle-type vehicle B is less than 2 m, and AR2 indicates an area where the distance from the saddle-ride type vehicle B is 2 m or more. Here, even when the user carrying the portable device 200 is at least 2 m away from the straddle-type vehicle B, the saddle-ride type vehicle is brought into a state in which the first operating portion 112 can be operated to release the locked state of the steering wheel. If B is set, there is a possibility that the saddle type vehicle B is stolen by a third party. Therefore, in order to prevent the straddle-type vehicle B from being stolen, when the portable device 200 is located outside the area AR1, it is set so that the vehicle-mounted device 100 and the portable device 200 cannot communicate with each other. Is located in the area AR1 and the reception intensity of the request signal is smaller than the first threshold, the first threshold needs to be set. In this way, an area where the reception intensity of the request signal received by the portable device 200 is equal to or more than the first threshold is set as the smart communicable area.

  FIG. 4 is a diagram for explaining the smart communicable area AR3 in the case where the transmitting antenna 136B of the on-vehicle device 100 is disposed at the position of the first operation unit 112. In the straddle-type vehicle B of FIG. 4, the unlocking operation of the storage box B1 is performed without through smart communication. If the transmitting antenna 136B is arranged at the position of the first operation unit 112 (position P1 in FIG. 4), a request signal transmitted from the transmitting antenna 136B and received by the portable device 200 located in the smart communicable area AR3. Is greater than or equal to the first threshold. In FIG. 4, AR4 indicates an area whose distance from the first operation unit 112 is 0.8 m or less. In the saddle-ride type vehicle B on which the in-vehicle device 100 is mounted, the user carrying the portable device 200 is located within an arc of 0.8 m from the first operation unit 112 (that is, within the arc of the area AR4). In this case, it is required that the steering wheel unlock operation can be performed (actual vehicle requirement for steering wheel unlocking). As shown in FIG. 4, if the transmitting antenna 136B is arranged at the position of the first operation unit 112, an arc whose distance from the first operation unit 112 is 0.8 m is included in the smart communicable area AR3. It is. Therefore, if the transmitting antenna 136B is arranged at the position of the first operation unit 112, the user carrying the portable device 200 located within an arc of 0.8 m from the first operation unit 112 can handle the steering wheel. Can be executed. In other words, if the transmitting antenna 136B is arranged at the position of the first operation unit 112, it is possible to satisfy the actual vehicle requirement for releasing the steering wheel lock.

  FIG. 5 is a diagram for explaining the smart communicable area AR5 in the case where the transmitting antenna 136B of the on-vehicle device 100 is disposed at the approximate center position (the position beside the seat) of the saddle type vehicle B. In the saddle-ride type vehicle B of FIG. 5, the unlocking operation of the storage box B1 is also performed via smart communication. If transmission antenna 136B is arranged at the approximate center position of straddle-type vehicle B (position P2 in FIG. 5), transmission is performed from transmission antenna 136B and received by portable device 200 located in smart communicable area AR5. The reception strength of the request signal is equal to or higher than the first threshold. In FIG. 5, AR6 indicates an area whose distance from the first operation unit 112 is 0.8 m or less. AR7 indicates an area whose distance from the second operation unit 122 is 0.8 m or less. As described above, in the saddle-ride type vehicle B on which the in-vehicle device 100 is mounted, the user who carries the portable device 200 is within a circular arc whose distance from the first operation unit 112 is 0.8 m (that is, the circular arc of the area AR6). (In), it is required that the steering wheel can be unlocked (actual vehicle unlocking requirement). As shown in FIG. 5, if transmitting antenna 136B is arranged at the approximate center position of saddle-ride type vehicle B, an arc at a distance of 0.8 m from first operation unit 112 forms smart communication possible area AR5. include. Therefore, if transmitting antenna 136B is arranged at the approximate center position of saddle-ride type vehicle B, a user carrying portable device 200 located within an arc of 0.8 m from first operation unit 112 may be used. , The operation of unlocking the handle can be performed. That is, if the transmitting antenna 136B is arranged at the approximate center position of the saddle-ride type vehicle B, it is possible to satisfy the actual vehicle requirement for releasing the steering wheel lock.

  On the other hand, as shown in FIG. 5, if transmitting antenna 136B is arranged at the approximate center position of straddle-type vehicle B, an arc having a distance of 0.8 m from second operation unit 122 (that is, area AR7). Is located outside the smart communicable area AR5. Therefore, if a threshold value equal to the threshold value (that is, the first threshold value) of the reception intensity of the request signal (specifically, the signal required for unlocking the handlebar) is set to the request signal (specifically, the signal required for unlocking the storage box) ), The user carrying the portable device 200 located outside the smart communicable area AR5 within the arc having a distance of 0.8 m from the second operation unit 122 is stored. The unlocking operation of the box B1 cannot be executed. That is, when the transmitting antenna 136B is disposed at the approximate center position of the saddle-ride type vehicle B, a request signal (specifically, a signal required for unlocking the steering wheel) reception intensity threshold (first threshold) and a request If the reception strength of the signal (specifically, the signal required for unlocking the storage box) is equal to the threshold value, the actual vehicle requirements for unlocking the storage box may not be satisfied.

FIG. 6 is a diagram illustrating a positional relationship between the transmitting antenna 136B of the vehicle-mounted device 100, the first operation unit 112, and the second operation unit 122 in the saddle-ride type vehicle operation permission device 1 according to the first embodiment.
In view of the problem described with reference to FIG. 5, in the saddle-ride type vehicle operation permission device 1 of the first embodiment, the first operation unit 112 and the second operation unit 122 are arranged at different positions. Further, transmission antenna 136B is arranged such that the distance between transmission antenna 136B and second operation unit 122 is equal to or greater than the distance between transmission antenna 136B and first operation unit 112. In the saddle-ride type vehicle B of FIG. 6, the unlocking operation of the storage box B1 is also performed via smart communication.

  On the other hand, simply arranging the transmission antenna 136B, the first operation unit 112, and the second operation unit 122 as shown in FIG. 6 cannot solve all the problems described with reference to FIG. That is, the user who carries the portable device 200 located outside the smart communicable area AR5 'within the arc of 0.8 m from the second operation unit 122 (that is, within the arc of the area AR7) is a storage box. The problem that the lock release operation of B1 cannot be executed still remains. Therefore, in the straddle-type vehicle operation permission device 1 of the first embodiment, the first threshold is set as the threshold of the reception intensity of the request signal (specifically, the signal required for releasing the steering wheel lock). That is, unlocking of the steering wheel is permitted when the reception intensity of the request signal is equal to or higher than the first threshold, and unlocking of the handle is not permitted when the reception intensity of the request signal is lower than the first threshold. Further, in the saddle-ride type vehicle operation permission device 1 of the first embodiment, the threshold of the reception intensity of the request signal (specifically, the signal required for unlocking the storage box) is not set. That is, unlocking of the storage box B1 is permitted when the request signal is received by the portable device 200, and unlocking of the storage box B1 is not permitted when the request signal is not received by the portable device 200. That is, when the reception strength of the request signal is zero or more, the unlocking of the storage box B1 is permitted.

Specifically, in the straddle-type vehicle operation permission device 1 of the first embodiment, as shown in FIG. 6, the reception intensity of the request signal in the area AR5 'is equal to or higher than the first threshold. Therefore, the user who carries the portable device 200 located within the arc of 0.8 m from the first operation unit 112 (that is, within the arc of the area AR6) can execute the handle unlock operation.
In addition, the reception strength of the request signal in the area AR8 larger than the area AR5 ′ becomes zero or more. Therefore, the user who carries the portable device 200 located within the arc of 0.8 m from the second operation unit 122 (that is, within the arc of the area AR7) can execute the unlocking operation of the storage box B1. it can. That is, the operation permission device 1 for a saddle-ride type vehicle according to the first embodiment can satisfy the actual vehicle requirement for unlocking the handlebar and the actual vehicle requirement for unlocking the storage box.

  FIG. 7 is a flowchart illustrating a flow of a process executed at the time of a handle unlock operation. 7, steps S10, S11, S30 to S34 show processing executed by the on-vehicle device 100, and steps S20 to S23 show processing executed by the portable device 200.

  First, the control unit 135 of the in-vehicle device 100 determines whether or not the first operation unit 112 has received a user operation requesting unlocking of the steering wheel (that is, energization of the solenoid 111) (Step S10). That is, the control unit 135 determines whether the first operation unit 112 is located at the ON position. If the first operation unit 112 has not received a user operation requesting unlocking of the steering wheel, the routine illustrated in FIG. 7 ends. When the first operation unit 112 receives a user operation requesting unlocking of the handle, the process proceeds to step S11. The transmission unit 136 of the on-vehicle device 100 transmits a request signal (Step S11).

  The receiving unit 220 of the portable device 200 receives the request signal transmitted by the transmitting unit 136 of the on-vehicle device 100 (Step S20). The encryption processing unit 231 of the portable device 200 checks whether the signal received by the receiving unit 220 is a signal transmitted from the vehicle-mounted device 100 (Step S21). If the signal received by the receiving unit 220 is not a signal transmitted from the vehicle-mounted device 100, the process returns to step S10. If the signal received by the receiving unit 220 is a signal transmitted from the vehicle-mounted device 100, the process proceeds to step S22. The reception intensity detector 232 detects (measures) the reception intensity of the request signal (step S22). Transmitter 240 of portable device 200 transmits an answer signal to the request signal (step S23). The control unit 230 includes information indicating the reception strength of the request signal in the answer signal.

  The receiving unit 137 of the on-vehicle device 100 receives the answer signal transmitted by the transmitting unit 240 of the portable device 200 (Step S30). The encryption processing unit 135A of the on-vehicle device 100 checks whether the signal received by the receiving unit 137 is a signal transmitted from the portable device 200 (Step S31). If the signal received by the receiving unit 137 is not a signal transmitted from the portable device 200, the process returns to step S10. When the signal received by the receiving unit 137 is a signal transmitted from the portable device 200, the process proceeds to step S32. The control unit 135 of the on-vehicle device 100 acquires the reception intensity of the request signal from the answer signal (Step S32).

  The reception strength determination unit 135B of the on-vehicle device 100 determines whether the reception strength RSSI1 of the request signal is equal to or greater than the first threshold th1 (Step S33). If the reception intensity RSSI1 of the request signal is less than the first threshold th1, the process returns to step S10. If the received signal strength RSSI1 is equal to or greater than the first threshold th1, the process proceeds to step S34. The solenoid drive circuit 132 of the vehicle-mounted device 100 supplies a drive current to the solenoid 111 based on a control signal from the control unit 135 (Step S34). As a result, the locked state of the handle of the straddle-type vehicle is released.

  FIG. 8 is a flowchart illustrating a flow of a process performed at the time of an unlocking operation of the storage box B1. 8, steps S100, S101, and S300 to S302 indicate processing executed by the vehicle-mounted device 100, and steps S200 to S203 indicate processing executed by the portable device 200.

  First, the control unit 135 of the vehicle-mounted device 100 determines whether or not the second operation unit 122 has received a user operation requesting unlocking of the storage box B1 (that is, operation of the actuator 121) (Step S100). That is, the control unit 135 determines whether the second operation unit 122 is located at the ON position. If the second operation unit 122 has not received the user operation requesting the unlocking of the storage box B1, the routine illustrated in FIG. 8 ends. If the second operation unit 122 receives a user operation requesting unlocking of the storage box B1, the process proceeds to step S101. The transmitting unit 136 of the on-vehicle device 100 transmits a request signal (Step S101).

The receiving unit 220 of the portable device 200 receives the request signal transmitted by the transmitting unit 136 of the on-vehicle device 100 (Step S200). The encryption processing unit 231 of the portable device 200 checks whether the signal received by the receiving unit 220 is a signal transmitted from the vehicle-mounted device 100 (Step S201). If the signal received by the receiving unit 220 is not a signal transmitted from the vehicle-mounted device 100, the process returns to step S100. If the signal received by the receiving unit 220 is a signal transmitted from the vehicle-mounted device 100, the process proceeds to step S202. The reception intensity detector 232 detects (measures) the reception intensity of the request signal (step S202). The transmitting unit 240 of the portable device 200 transmits an answer signal to the request signal (Step S203).
The control unit 230 includes information indicating the reception strength of the request signal in the answer signal.

  The receiving unit 137 of the on-vehicle device 100 receives the answer signal transmitted by the transmitting unit 240 of the portable device 200 (Step S300). The encryption processing unit 135A of the on-vehicle device 100 checks whether the signal received by the receiving unit 137 is a signal transmitted from the portable device 200 (Step S301). If the signal received by the receiving unit 137 is not a signal transmitted from the portable device 200, the process returns to step S100. If the signal received by the receiving unit 137 is a signal transmitted from the portable device 200, the process proceeds to step S302.

  The actuator drive circuit 133 of the vehicle-mounted device 100 supplies a drive current to the actuator 121 based on a control signal from the control unit 135 (Step S302). As a result, the locked state of the storage box B1 is released.

  In the straddle-type vehicle operation permission device 1 of the first embodiment, as shown in FIG. 6, the distance between the transmission antenna 136B and the second operation unit 122 is equal to or greater than the distance between the transmission antenna 136B and the first operation unit 112. It is. Further, as described above, the threshold of the reception intensity of the request signal (specifically, the signal required for unlocking the storage box) is not set. Therefore, the transmission output when the transmission antenna 136B transmits a request signal (specifically, a signal necessary for unlocking the handlebar) and the transmission antenna 136B are a request signal (specifically, a signal required for unlocking the storage box). It is not necessary to make the transmission output different from the transmission output. As a result, the transmission output when the transmission antenna 136B transmits a signal required for unlocking the steering wheel is different from the transmission output when the transmission antenna 136B transmits a signal required for unlocking the storage box. The configuration of the transmission unit 136 can be simplified. That is, the transmission output when the transmission antenna 136B transmits a request signal (specifically, a signal required for unlocking the steering wheel) and the transmission antenna 136B transmits a request signal (specifically, a signal required for unlocking the storage box) The control unit 135 can appropriately permit the operation of the solenoid 111 and the operation of the actuator 121 without having to make the transmission output different from the transmission output when transmitting. According to the straddle-type vehicle operation permission device 1 of the first embodiment, since the smart communicable area can be limitedly expanded, there is a possibility that a third party may operate by simply expanding the smart communicable area. , While meeting the demand for expanding the smart communicable area by increasing the number of operation units.

  As described above, the operation permission device 1 for a saddle-ride type vehicle of the first embodiment can permit the operation of the solenoid 111 and the operation of the actuator 121 by two-way communication between the in-vehicle device 100 and the portable device 200. It is possible to achieve both theft prevention and the wide range of communication range. Further, the operation permission device 1 for a saddle-ride type vehicle according to the first embodiment transmits a request signal (specifically, a signal required for releasing the steering wheel lock) and a request signal (specifically, a storage signal). It is possible to secure a communication area that satisfies the requirements of the actual vehicle for unlocking the steering wheel and the requirements for unlocking the storage box, without having to differ from the transmission output when transmitting the signal required for unlocking the box.
