Description

TECHNICAL FIELD

[0001] The present application relates to a straddle-type vehicle and a storage medium.

[0002] This application is based on Japanese Patent Application No. 2020-208272 filed on December 16, 2020, and the content thereof is incorporated herein by reference. BACKGROUND

[0003] In the field of wireless door locks, there is a technology that sets a communication area of a vehicle-mounted device and a wireless key in advance in the periphery of a vehicle, performs an authentication process based on a communication result with a wireless key present in the set communication area, and releases the lock in the case where authenticity is confirmed. There is also a technology that uses a portable device as such a wireless key, estimates the distance between the vehicle-mounted device and the portable device based on the signal strength from the vehicle-mounted device, and executes an authentication process in the case where it is determined that the portable device is present in the periphery of the vehicle.

[0004] For example, in order to detect the position of a portable device with high precision, to detect a portable device approaching a vehicle early, there is known a portable device that sets the signal strength of a response signal high in a region where the reception sensitivity of a signal from a vehicle-mounted device is low (for example, refer to Patent Literature 1).

[0040] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. Figure 1 This is a perspective view of a motorized two-wheeled vehicle 11, which is an example of a vehicle used in the implementation of this method. Figure 1 As shown, the motorized two-wheeled vehicle 11 is, for example, a small motorized two-wheeled vehicle of the unit swing type.

[0041] <Vehicle as a whole>

[0042] like Figure 1 As shown, the motorized two-wheeled vehicle 11 has a front wheel 13 as a steering wheel and a rear wheel 14 as a drive wheel. The front wheel 13 is supported by a front fork 16 and can be steered via a handlebar 12. The rear wheel 14 is supported by a swing unit 20 and can be driven by a reciprocating engine (internal combustion engine, hereinafter referred to as the engine) 21, which will be described later. The swing unit 20 integrally includes the engine 21 and a continuously variable transmission (CVT) such as a V-belt (not shown).

[0043] The steering system components including the handlebar 12, the front fork 16, and the front wheel 13 are supported turnably at a front end portion of a frame not shown. The swing unit 20 and the rear wheel 14 are supported up-and-down swingably at a lower rear portion of the frame. A storable side stand 17 is provided at a lower left portion of the frame, and supports the vehicle body in a standing attitude inclined to the left side. The periphery of the frame is covered by a body cover 15.

[0044] The motorized two-wheeled vehicle 11 is provided with a pair of left and right footboards 19 for a driver seated on a seat 18 to put his feet, a center passage CT extending in the vehicle front-and-rear direction between the left and right footboards 19, a front vehicle body FB connected to the front of the center passage CT and the left and right footboards 19, and a rear vehicle body RB connected to the rear of the center passage CT and the left and right footboards 19.

[0045] A headlamp 22a and a front direction indicator lamp 22b are arranged at an upper front portion of the front vehicle body FB. A rear combination lamp 23 including a tail lamp, a brake lamp, and a rear direction indicator lamp is arranged at a rear portion of the rear vehicle body RB. The seat 18 for a passenger to sit on is supported on the rear vehicle body RB. A fuel cap 24 that opens and closes a space for an oil filler is provided on an upper surface of the center passage CT.

[0046] The seat 18 is turned up and down, for example, about a hinge shaft arranged at a front end portion, to open and close an upper portion of the rear vehicle body RB. A seat lower storage portion 50 is arranged below the seat 18.

[0047] The seat lower storage portion 50 is an example of a storage portion having a closable enclosed space that needs to be unlocked by the seat 18 as a lid.

[0048] In a closed state in which the seat 18 closes the upper portion of the rear vehicle body RB, a passenger can sit on the seat 18. In an open state in which the seat 18 opens the upper portion of the rear vehicle body RB, the seat lower storage portion 50 below the seat 18 can be operated.

[0049] A display panel 26 is arranged at an upper portion of the front vehicle body FB. The display panel 26 is provided with, for example, an LCD (Liquid Crystal Display), an organic EL (Electro luminescence) display device, or the like. The display panel 26 displays intelligent indicators including a speedometer, messages to be provided to a user, diagrams, and the like.

[0050] A handlebar lock module 27 is stored inside the front vehicle body FB. The handlebar lock module 27 integrally has a handlebar lock mechanism 28 as a main body portion, an intelligent control unit 300 described later, and a main switch 30 as a main power source switch of the motorized two-wheeled vehicle 11.

[0051] One or more front storage portions 60 are provided on the inner side of the front body FB. The front storage portion 60 has an opening portion without a lid on the upper portion, and is an example of a storage portion having a space in which locking is not required.

[0052] The seat under storage portion 50 and the front storage portion 60 each have a space (storage space), and a connection terminal 50A and a connection terminal 60A that connect one end of a cable are provided in a portion of each storage space. The connection terminal 50A and the connection terminal 60A are, for example, USB-shaped terminals that are connected to a USB port of a USB charger described later. The connection terminal 50A and the connection terminal 60A connect a device via a USB cable, thereby connecting the device to the USB charger described later.

[0053] Note that a wireless charger 50B and a wireless charger 60B that wirelessly connect to a device stored in the storage space to perform wireless power transmission to the device can be provided in the seat under storage portion 50 and the front storage portion 60, respectively. The wireless charger 50B and the wireless charger 60B wirelessly connect to the device stored in the seat under storage portion 50 or the front storage portion 60 to charge the device.

[0054] That is, the seat under storage portion 50 and the front storage portion 60 are spaces in which a device is connected to a charger in a wired or wireless manner to be able to be charged, and are closable enclosed spaces.

[0055] Figure 2 is an explanatory view of a main switch knob of a motorized two-wheeled vehicle. The main switch knob 31 has: an off position P1 that sets the main switch 30 to an off state; an on position P2 that sets the main switch 30 to an on state; a seat / fuel lock release position P3 that is between the off position P1 and the on position P2 and enables opening operation of the seat 18 and the fuel cap 24; and a lock position P4 that is rotated in the opposite direction from the off position P1 to the on position P2 with a press, and sets the lock of each portion of the vehicle including the handle lock to a locked state. In a state in which the main switch 30 is not started, the main switch knob 31 is located at the off position P1.

[0056] When the main switch knob 31 is in the seat / fuel lock release position P3, operation of the seat / fuel lock release switch 32 adjacent to the main switch knob 31 becomes possible or valid. The seat / fuel lock release switch 32 is an interactive switching switch. One of the seat / fuel lock release switch 32 is a switch that selects unlocking of the seat 18. The other of the seat / fuel lock release switch 32 is a switch that selects unlocking of the fuel cap 24.

[0057] The main switch 30 is provided with a main switch knob 31 as an operation portion on the inner panel 25 on the side of the floorboard 19 (rear surface side) of the front body FB. In a case where authenticity is confirmed by an authentication process of an authentication target (for example, the user terminal device 100) by a remote control key of the motorized two-wheeled vehicle 11, a rotational operation of the main switch knob 31 becomes possible or effective (hereinafter, referred to as a main switch unlocking state).

[0058] The main switch 30 becomes a start state by the authentication process confirming authenticity or a prescribed operation (for example, an operation of pressing the main switch knob 31) of the main switch knob 31 after the authentication process confirming authenticity. When the main switch 30 becomes the start state, for example, an illumination device provided to the main switch 30 is turned on and the operation of the main switch knob 31 becomes possible or effective.

[0059] For example, the main switch 30 becomes an on state by an operation of bringing the main switch knob 31 to the on position P2. Note that, hereinafter, a state where the main switch 30 does not become the on state after the authentication process confirms authenticity or after the main switch 30 starts is referred to as a main switch on standby state.

[0060] In addition, by bringing the main switch 30 to the start state, it is possible to supply power to the control device 40 described later to start the engine 21, and it is possible to release the electromagnetic lock (an electrically operated locking device operated by a solenoid) 70 of the seat 18, the fuel cap 24, and the like. That is, by moving the main switch knob 31 to the seat / fuel lock release position P3 and operating the seat / fuel lock release switch 32 while the main switch 30 is in the start state, it is possible to release the lock of the seat 18 or the lock of the fuel cap 24, and the like.

[0061] On the other hand, by cutting off the communication between the user terminal device 100 and the motorized two-wheeled vehicle 11 in the main switch unlocking state or by elapsing a prescribed time, the operation of the main switch knob 31 becomes impossible or ineffective (hereinafter, referred to as a main switch locking state). The communication between the user terminal device 100 and the motorized two-wheeled vehicle 11 is cut off, for example, by the user terminal device 100 being away or by the user terminal device 100 being kept in a closed space or the like. Note that, by becoming the main switch locking state, the equipment such as the seat 18 also becomes a locked state.

[0062] Figure 3Fig. 6 is an explanatory view of the vicinity of a start switch 29 of the motorized two-wheeled vehicle 11. The start of the engine 21 is performed by holding the brake lever 29a on the right side of the handlebar 12 and pressing the start switch 29 with the main switch 30 in the on state. By the pressing of the start switch 29, the engine start control section 42 of the control device 40 described later drives the starter motor 21a attached to the engine 21 and controls the ignition and fuel injection, thereby starting the engine 21.

[0063]

[0064] Figure 4 Fig. 7 is a functional block diagram of the vehicle-mounted communication system 1 in the embodiment. The vehicle-mounted communication system 1 includes an intelligent control unit 300 and the control device 40. The intelligent control unit 300 is a constituent element of the intelligent key system 2 described later.

[0065] The intelligent control unit 300 is connected with, for example, the start switch 29, the main switch 30, the electromagnetic lock 70 (including the lock devices of the parts of the vehicle), the display panel 26, the control device 40, a notification drive device (not shown) which operates various notification mechanisms in accordance with the operation of the intelligent key system 2, and the like. The notification drive device performs at least one of, for example, a visual indication such as blinking of a hazard warning light and an audible indication such as sounding of an electronic horn (response) when the locking and unlocking of the lock devices of the parts of the vehicle are performed by the intelligent key system 2. Thereby, the user can know the situation that the locking and unlocking of the lock devices of the parts of the vehicle are performed.

[0066] The control device 40 is, for example, an integrated ECU (Electric Control Unit) which functions as a control section of the vehicle-mounted communication system 1 as a whole. Note that the control device 40 can also be a Fi-ECU (Fuel Injection-Engine Control Unit). Hereinafter, the control device 40 is referred to as the ECU 40. The ECU 40 is inputted with an on signal from the main switch 30 and an engine start operation signal from the start switch 29 by the intelligent control unit 300. In addition, the ECU 40 is inputted with a stand rack use detection signal from the stand rack switch 17a which detects the standing state of the stand rack 17, various detection signals which detect the operation state of the engine 21, and the like.

[0067] The ECU 40 is provided with an engine control section 41 which controls the driving of the engine 21 and the like, and an engine start control section 42 which performs the start control of the engine 21.

[0068] ​The engine control section 41 and the engine start control section 42 are realized by, for example, a processor such as a CPU (Central Processing Unit), a GPU (GraPhics Processing Unit), or the like executing a program (software). Also, part or all of the above-described components can be realized by hardware (including circuitry) such as an LSI (Large Scale Integration), an ASIC (Application Specific Integrated Circuit), a FPGA (Field-Programmable Gate Array), or the like, and can also be realized by a cooperation of software and hardware. The program can be stored in advance in a storage section of the ECU 40, or can be stored in a detachable storage medium such as a DVD, a CD-ROM, or the like, and installed in the storage section by mounting the storage medium in a drive device.

[0069] The smart key system 2 is, for example, a system that utilizes a communication device having a near distance communication function as a key of the motorcycle 11. The smart key system 2 is capable of locking and unlocking each part of the motorcycle 11. Note that the communication function of the smart key system 2 is not limited to the near distance communication function.

[0070] For example, the smart key system 2 has a user terminal device 100 held by a user such as a driver, and a smart control unit 300 as an in-vehicle device. The smart control unit 300 performs, for example, ID authentication of the user terminal device 100 by performing bidirectional communication with the user terminal device 100. The smart key system 2, in a case where the ID authentication of the user terminal device 100 is performed, unlocks the lock of the seat 18 or the like, and makes it possible to start the engine 21 and unlock each part of the vehicle.

[0071] <Smart Control Unit>

[0072] Figure 5Fig. 17 is a functional block diagram of the smart control unit 300. The smart control unit 300 has, for example, a power supply circuit 301, a main switch input detection circuit 302, a starter switch input detection circuit 303, an electromagnetic lock drive circuit 304, a knob switch input detection circuit 305, a Bluetooth communication circuit 306, a USB power supply drive circuit 307, a display panel drive circuit 308, an ECU communication circuit 309, a smart CPU 310, a Bluetooth antenna 320, and a storage section 350. Here, an example in which the smart control unit 300 uses Bluetooth as a communication means is described, but the present application is not limited thereto. For example, the smart control unit 300 can use wireless LAN (wi-fi), infrared communication, or the like for close-range communication. Note that Bluetooth is a registered trademark. Hereinafter, the description of Bluetooth as a registered trademark is omitted. The smart control unit 300 can perform authentication processing based not only on Bluetooth communication as described below but also on the result of communication with the motorcycle 11 via a wide area network NW.

[0073] The power supply circuit 301 receives power required for processing of the smart control unit 300 from a power supply on the motorcycle 11 side and supplies the power to each circuit.

[0074] The main switch input detection circuit 302 is connected to the main switch 30 and detects the operation of the main switch knob 31 being pressed in. Note that the operation of the main switch knob 31 being pressed in can mean various operations depending on the state of the smart control unit 300, for example, an operation including a request for unlocking of the main switch 30, an operation indicating immediate end of the disconnection processing of the main switch 30, and the like.

[0075] The starter switch input detection circuit 303 is connected to the starter switch 29 and detects an operation indicating start of the engine or an operation indicating stop of the engine and outputs the detection result to the smart CPU 310.

[0076] The electromagnetic lock drive circuit 304 is connected to the electromagnetic lock 70 and is controlled by the smart CPU 310. The electromagnetic lock drive circuit 304 sets the seat 18, the fuel cap 24, the handle lock mechanism 28, the main switch knob 31, and the like to a locked state or an unlocked state by exciting or de-exciting the electromagnetic lock 70.

[0077] The knob switch input detection circuit 305 is connected to the main switch knob 31 and inputs a signal indicating the operation scale at which the main switch knob 31 is located. The knob switch input detection circuit 305 detects, based on the input signal, the off operation (off position P1), the on operation (on position P2), the unlock operation (seat / fuel lock release position P3) that makes the opening operation of the seat 18 and the fuel cap 24 possible, and the lock operation (lock position P4) that locks each part of the vehicle including the handle lock in the locked state, and outputs the detection result to the intelligent CPU 310.

[0078] The Bluetooth communication circuit 306 communicates with a communication device present in a communication area using the Bluetooth antenna 320. The communication area is an area within a prescribed distance from the Bluetooth antenna 320. For example, the Bluetooth communication circuit 306 emits a beacon signal to detect a communication device present in the communication area, and establishes Bluetooth communication with the detected communication device.

[0079] The USB power source drive circuit 307 is connected to the USB charger 400 to cause the power source circuit 301 of the USB charger 400 to be driven. The USB charger 400 charges a terminal device connected by a wired or wireless method. Hereinafter, an example in which the USB charger 400 charges a terminal device connected by a wire to the connection terminal 50A or the connection terminal 60 via a cable will be described, and a description of a case in which a terminal device connected by a wireless method is charged will be omitted. As for the latter, the part of the description in which charging is performed via a cable will be changed to a description in which wireless power transmission is performed to charge a terminal device.

[0080] The USB charger 400 has, for example, a power source circuit 401, a charger output control circuit 402, a first USB port 403, and a second USB port 404. The first USB port 403 is connected to the connection terminal 50A of the seat lower housing portion 50 by a wired method. The second USB port 404 is connected to the connection terminal 60A of the front housing portion 60 by a wired method. The power source circuit 401 supplies power supplied from the power source of the motorcycle 11 side to a terminal device connected to the first USB port 403 or the second USB port 404 via a USB cable.

[0081] The display panel drive circuit 308 is connected to the display panel 26 and drives the display panel 26.

[0082] The ECU communication circuit 309 is connected to the ECU 40 and communicates by a wired method. The ECU communication circuit 309 transmits information output from the intelligent CPU 310 to the ECU 40.

[0083] The storage portion 350 stores, for example, setting authentication mode information 351, a setting threshold 352, and an ID 353 of a registered person.

[0084] The set authentication mode information 351 is information indicating a currently set authentication mode. The authentication mode includes, for example, a normal authentication mode and a simple authentication mode. The normal authentication mode is a mode in which a case where an authentication target exists in an authentication area is taken as an authentication execution condition (a condition for executing an authentication process), and the authentication process is executed in a case where the authentication execution condition is satisfied. The simple authentication mode is a mode in which the authentication process is executed even in a case where the authentication execution condition is not satisfied. Note that the set authentication mode information 351 can also include information indicating a result (authentication success, authentication failure) obtained by the authentication process.

[0085] The set threshold value 352 is a threshold value of a received electric wave strength (hereinafter, referred to as RSSI (Received Signal Strength Indication)) registered by a prescribed registration process. From the viewpoint of security, the set threshold value is a reference value for defining an area (hereinafter, referred to as an authentication area) in which an authentication target existing in the periphery of the motorcycle 11 can be detected. The set threshold value is set to a value at which the authentication process is not executed for an authentication target that departs from the motorcycle 11.

[0086] The registrant ID 353 is information indicating the authenticity of the user terminal device 100, and is identification information given to a registrant in order to perform ID authentication. Note that the information indicating the authenticity of the user terminal device 100 is not limited to the ID information registered in advance. For example, it can be a random number generated for a limited use period or the like.

[0087] The smart CPU 310 has, for example, a switch control section 311, an operation instruction section 312, an electromagnetic lock control section 313, a Bluetooth communication control section 314, an authentication section 315, a display control section 316, an acquisition section 317, and a mode change section 318. The above-described switch control section 311, operation instruction section 312, electromagnetic lock control section 313, Bluetooth communication control section 314, authentication section 315, display control section 316, acquisition section 317, and mode change section 318 are realized, for example, by a processor such as a CPU, a GPU, or the like executing a program (software). In addition, part or all of the above-described components can be realized by hardware (including circuitry) such as an LSI, an ASIC, an FPGA, or the like, and can also be realized by cooperation of software and hardware. The program can be stored in advance in the storage section 350, or can be stored in a detachable storage medium such as a DVD, a CD-ROM, or the like, and installed in the storage section by mounting the storage medium to a drive device.

[0088] The switch control section 311 controls the rotation of the main switch knob 31 based on the authentication result authenticated by the authentication section 315. For example, in a case where the authenticity of the user terminal device 100 is confirmed by the authentication process, the switch control section 311 sets the rotation operation of the main switch knob 31 as possible or valid (i.e., sets to the main switch unlocked state). Not limited thereto, in a case where the authenticity of the user terminal device 100 is confirmed by the authentication process, the switch control section 311 can also set the operation of the start switch 29, the seat / fuel lock release switch 32, and other switches as possible or valid.

[0089] On the other hand, in a case where the authenticity of the user terminal device 100 is not confirmed by the authentication process or the communication between the user terminal device 100 and the motorcycle 11 is cut off, the switch control section 311 sets the rotation operation of the main switch knob 31 as impossible or invalid (i.e., sets to the main switch locked state).

[0090] The operation instruction section 312 acquires the input operation content based on the information input from the main switch input detection circuit 302, the start switch input detection circuit 303, or the knob switch input detection circuit 305, and determines the control content corresponding to the acquired operation content. The operation instruction section 312 outputs an instruction corresponding to the determined control content to the control target (or a control section that controls the control target) according to the determined control content.

[0091] For example, in a case where the start switch 29 is pressed in a state where the main switch 30 is in the on state and the brake lever 29a on the right side of the handlebar 12 is held by the user, which is detected by the start switch input detection circuit 303 or the like, the operation instruction section 312 detects the operation that instructs the start of the engine. In a case where the operation that instructs the start of the engine is detected, the operation instruction section 312 transmits the engine start permission signal to the ECU 40 via the ECU communication circuit 309, with the condition that the authenticity of the user terminal device 100 is confirmed by the authentication process.

[0092] In addition, in a case where the operation of pressing the main switch knob 31 is detected in the initial state, the operation instruction section 312 acquires the case that instructs the unlocking of the main switch 30, and controls the electromagnetic lock drive circuit 304 so as to unlock the main switch 30.

[0093] In addition, in a case where the on operation (operation of placing the main switch knob 31 at the on position P2) is detected by the knob switch input detection circuit 305 in the main switch on standby state, the operation instruction section 312 executes the processing flow in a case where the main switch 30 is in the on state.

[0094] The electromagnetic lock control section 313 controls the electromagnetic lock 70 based on the authentication result authenticated by the authentication section 315. For example, in a case where the authenticity of the user terminal device 100 is confirmed by the authentication process, the electromagnetic lock control section 313 controls the electromagnetic lock drive circuit 304 so as to become the main switch unlock state. In this state, for example, in a case where information indicating the unlock operation of the seat 18 is input from the knob switch input detection circuit 305, the electromagnetic lock control section 313 controls the electromagnetic lock 70 so as to make the opening operation of the seat 18 possible. On the other hand, in a case where information indicating the lock operation of the seat 18 is input from the knob switch input detection circuit 305, the electromagnetic lock control section 313 controls the electromagnetic lock 70 so as to make the opening operation of the seat 18 and the fuel cap 24 impossible. In a case where the communication with the user terminal device 100 is cut off is detected by the Bluetooth communication control section 314, the electromagnetic lock control section 313 controls the electromagnetic lock drive circuit 304 so as to make the main switch 30 and the seat 18 become the lock state.

[0095] The Bluetooth communication control section 314 controls the Bluetooth communication circuit 306, and performs communication with the user terminal device 100 existing in the communication area using the Bluetooth antenna 320. For example, the Bluetooth communication control section 314 transmits a beacon signal from the Bluetooth antenna 320, and determines whether or not there is a responding user terminal device 100. In a case where there is a user terminal device 100 responding to the beacon signal, the Bluetooth communication control section 314 continues the communication with the user terminal device 100. On the other hand, in a case where there is no response to the beacon signal, the Bluetooth communication control section 314 cuts off the communication with the user terminal device 100.

[0096] The authentication section 315, in a case where the authentication process based on the normal authentication mode is executed, performs a prescribed preliminary process and a prescribed authentication process based on the information received via the Bluetooth antenna 320. The preliminary process is, for example, a process of determining whether or not the RSSI value of the signal received via the Bluetooth antenna 320 is equal to or greater than the set threshold value registered in the storage section 350. The authentication section 315, in a case where it is determined by the preliminary process that the RSSI value of the signal received via the Bluetooth antenna 320 is equal to or greater than the set threshold value registered in the storage section 350, executes the authentication process.

[0097] As the authentication process, the authentication section 315, in a case where the ID information received from the user terminal device 100 coincides with the registrant ID registered in advance, authenticates that it is legitimate information from the registrant registered in advance. That is, the authenticity of the user terminal device 100 is confirmed.

[0098] In a case where the ID information received from the user terminal device 100 is authenticated by the authentication section 315, the electromagnetic lock control section 313 executes the above-described unlock process.

[0099] Note that by taking a case where the RSSI value is equal to or higher than a set threshold as the authentication execution condition, authentication processing can be executed if the user is in the vicinity of the motorcycle 11 on the basis of the distance between the user terminal device 100 and the motorcycle 11 being presumed. Thus, the security against theft can be improved.

[0100] In addition, the authentication section 315 executes authentication processing based on the simple authentication mode regardless of whether the authentication execution condition is satisfied or not. For example, the authentication section 315 does not execute the determination processing of whether the RSSI value is equal to or higher than a set threshold, but executes authentication processing based on the ID information. That is, the authentication section 315 executes authentication processing without the preliminary processing.

[0101] The display control section 316 controls the display panel drive circuit 308 to cause the display panel 26 to display prescribed information.

[0102] The acquisition section 317 acquires information indicating the state of the user terminal device 100 with respect to the motorcycle 11. For example, the acquisition section 317 acquires information indicating the connection state of the USB charger 400 and the user terminal device 100 from the USB charger 400 and the user terminal device 100. Specifically, the acquisition section 317 receives the identification information of the user terminal device 100 from the user terminal device 100 together with information indicating that the user terminal device 100 is in charging. In addition, the acquisition section 317 acquires information indicating that a device is connected via a cable to the connection terminal 50A or the connection terminal 60A from the USB charger 400, and identification information of the device connected via a cable to the connection terminal 50A or the connection terminal 60A.

[0103] Not limited to this, the user terminal device 100 can be preset to display the confirmation screen if a prescribed display condition of the confirmation screen is satisfied, and thus the acquisition section 317 acquires information indicating the state of the user terminal device 100 with respect to the motorcycle 11. For example, the display condition of the confirmation screen includes: (A) a case where the user terminal device 100 is connected to the motorcycle 11 via a cable connected to the connection terminal 50A or the connection terminal 60A; (B) a case where power supply to the USB charger 400 is started; and (C) a case where the user terminal device 100 is in charging. In this way, the acquisition section 317 can acquire information indicating a case where the user terminal device 100 is connected to the motorcycle 11 via a cable connected to the connection terminal 50A or the connection terminal 60A if information indicating that either "Yes" or "No" is touched in the confirmation screen is received from the user terminal device 100.

[0104] In addition, the acquisition unit 317 acquires information indicating that the user terminal device 100 is stored in the under-seat storage 50 or the front storage 60. For example, it is assumed that the following operation is performed: the user terminal device 100 is notified of the fact that the user terminal device 100 is stored in the under-seat storage 50 or the front storage 60 by the user using the user terminal device 100 to the intelligent control unit 300. In this case, the acquisition unit 317 acquires information indicating that the user terminal device 100 is stored in the under-seat storage 50 or the front storage 60 from the user terminal device 100. Note that in a case where a setting space for the user terminal device 100 and a sensor are prepared in advance in a part of the under-seat storage 50 or the front storage 60, and the sensor detects what is placed in the setting space, in this case, the acquisition unit 317 acquires information indicating that the user terminal device 100 is stored in the under-seat storage 50 or the front storage 60 from the sensor.

[0105] The mode changing unit 318 determines whether or not the change condition for changing to the easy authentication mode is satisfied, for example, on the basis of the information acquired by the acquisition unit 317. In a case where the change condition for changing to the easy authentication mode is satisfied, the mode changing unit 318 changes the set authentication mode from the normal authentication mode to the easy authentication mode. Specifically, the mode changing unit 318 saves information indicating the fact that the easy authentication mode is set as the set authentication mode information 351 in the storage unit 350.

[0106] The mode changing unit 318 changes to the easy authentication mode, for example, on the condition that the user's consent is obtained. The mode changing unit 318 displays a confirmation screen on the user terminal device 100 each time in a case where it is determined that the change condition for changing to the easy authentication mode is satisfied, to obtain the user's consent (whether or not to change). Not limited thereto, the mode changing unit 318 can also obtain the user's consent in advance and register it in the storage unit 350. By thus making the user's consent a condition for changing, it is possible to suppress a decrease in security.

[0107] The change condition includes, for example, (1) a case where the user terminal device 100 is connected to the USB charger 400 via the cable. In this way, it is presumed that the user terminal device 100 is present in the vicinity of the motorcycle 11 on the basis of the fact that the motorcycle 11 is connected to the user terminal device 100, and thus it is possible to solve the problem in terms of security in the authentication processing based on the easy authentication mode even if the strength of the RSSI value is ignored.

[0108] Further, the change condition can include (2) a case where the connection terminal with which the user terminal device 100 is connected to the USB charger 400 is present in the closable enclosed space. The closable enclosed space is, for example, the storage space in the under-seat storage portion 50, and the combination of the change condition (1) and the change condition (2) includes a case where the user terminal device 100 is directly connected to the connection terminal 50A provided in the under-seat storage portion 50. In this way, even in a case where the radio wave intensity is attenuated because the user terminal device 100 is present in the enclosed space, the authentication process can be executed, and since the user terminal device 100 is not exposed to the outside, the user terminal device 100 can be protected during travel.

[0109] Further, the change condition can include (3) a case where the closable enclosed space is unlocked in a state where the authenticity is confirmed by the authentication process and is locked in a state where the main switch is locked.

[0110] In addition, the change condition can include (4), in addition to (1), a case where, in the storage portion provided in the motorcycle 11, the connection terminal with which the user terminal device 100 is connected to the USB charger is present in a storage portion having signal intensity attenuation from the smart control unit 300 (hereinafter, referred to as a signal attenuation storage portion). The signal attenuation storage portion is, for example, the under-seat storage portion 50 or the front storage portion 60, and the combination of the change condition (1) and the change condition (4) includes a case where the user terminal device 100 is directly connected to the connection terminal 50A provided in the under-seat storage portion 50, and a case where the user terminal device 100 is directly connected to the connection terminal 60A provided in the front storage portion 60.

[0111] In addition, the change condition can include (5) a case where the user terminal device 100 is stored in the under-seat storage portion 50 or the front storage portion 60. This change condition (5) can be combined with at least one of the change conditions (1), (2), (3), and (4).

[0112] In addition, the change condition can include (6), in addition to (5), a case where the user terminal device 100 is connected to the wired connection connection terminal 50A or the connection terminal 60A provided in the under-seat storage portion 50 or the front storage portion 60. In this way, the authentication process can be more reliably executed in the storage portion in which the signal intensity is easily attenuated.

[0113] Not limited thereto, the front storage portion 60 can also be an enclosed space provided with a cover that is unlocked by the authentication process like the seat 18. In this case, the front storage portion 60 is also included in the closable enclosed space in the change condition (2), and the combination of the change condition (1) and the change condition (2) includes a case where the user terminal device 100 is directly connected to the connection terminal 60A provided in the front storage portion 60.

[0114] Note that the mode changing unit 318 can also change the set authentication mode from the normal authentication mode to the simple authentication mode at a prescribed change timing, in a case where the change condition for changing to the simple authentication mode is satisfied. Details of the prescribed change timing are described later.

[0115] Thus, in a case where the change condition for changing to the simple authentication mode is satisfied, the next authentication process is changed to the simple authentication mode, and the authentication process is executed regardless of whether or not the RSSI value is equal to or greater than the set threshold value, whereby the authentication process can be performed more reliably.

[0116] Next, an example of authentication of the smart key system 2 with the user terminal device 100 will be described. When the user terminal device 100 in the power-on state enters a prescribed authentication area (described later), the smart key system 2 performs bidirectional communication between the user terminal device 100 and the smart control unit 300, for example, using the pressing of the main switch knob 31 as a trigger. Through the bidirectional communication, the smart control unit 300 acquires ID information from the user terminal device 100, and performs authentication of the user terminal device 100. When the authentication of the user terminal device 100 is completed, the turning-on operation of the main switch knob 31 becomes possible, the handle lock is released, and release of the locks of the various parts of the vehicle becomes possible.

[0117] In a case where the user terminal device 100 enters the prescribed authentication area, for example, the determination is made in a prior process performed by the smart control unit 300, and the condition is satisfied in a case where the RSSI value of the signal received from the user terminal device 100 is equal to or greater than the set threshold value. The authentication area is, for example, a range in which the RSSI value of the set threshold value is ensured, and is a range of several m or so in radius centered on a prescribed position of the motorcycle 11.

[0118] The smart key system 2 stops the communication between the user terminal device 100 and the smart control unit 300 when the user terminal device 100 exits the authentication area or when the power of the user terminal device 100 is turned off. The smart key system 2 also stops the communication between the user terminal device 100 and the smart control unit 300 according to the turning-off operation (turning operation to the off position PI) of the main switch knob 31.

[0119]

[0120] Figure 6 ​is a functional block diagram of the user terminal device 100. The user terminal device 100 is, for example, a portable telephone such as a smartphone, a tablet terminal, a PDA (Personal Digital Assistant), or the like, and is a mobile terminal device having at least a communication function and a display function. The user terminal device 100 has, for example, a communication section 110, an input section 120, a display section 130, a storage section 150, and an application execution section 170.

[0121] The communication section 110 is, for example, a wireless module for utilizing Bluetooth or the like, and has an antenna, a transmission / reception device, and the like. The input section 120 includes, for example, a part or all of a touch panel TP formed integrally with the display section 130, various keys, buttons, a dial switch, a mouse, and the like. The display section 130 is, for example, an LCD (Liquid Crystal Display), an organic EL (Electroluminescence) display device, or the like.

[0122] The storage section 150 is realized by, for example, a RAM (Random Access Memory), a ROM (Read Only Memory), a flash memory, an SD card, a register, or the like. The storage section 150 stores therein a smart key application 151. The smart key application 151 is a program that causes the display section 130 to display an interface for utilizing the user terminal device 100 as a smart key, and causes the user terminal device 100 to execute processing based on information input via the interface.

[0123] The application execution section 170 is realized by, for example, a CPU or the like executing the smart key application (program) 151 stored in the storage section 150. The smart key application 151 can also be downloaded from another device via a network NW, or can be pre-installed in the user terminal device 100.

[0124] <Usage Case 1>

[0125] Figure 7 is a diagram for explaining the usage case 1. The usage case 1 is a usage case in which, after the master switch 30 becomes the master switch unlocked state by confirming the authenticity of the user terminal device 100, the master switch 30 remains in the non-on state for a prescribed time, and the lock of the equipment such as the seat 18 is automatically locked.

[0126] (Process Al) First, the user operates the user terminal device 100 held by the user to start the smart key application 151 in the vicinity of the motorcycle 11. The user terminal device 100 executes the smart key application 151 and establishes Bluetooth communication with the smart control unit 300 of the motorcycle 11. The authentication process performed here is a process based on the normal authentication mode. In a case where the user terminal device 100 has entered the authentication area, since the RSSI value is equal to or higher than the set threshold value, the smart control unit 300 performs the authentication process.

[0127] When the authenticity of the user terminal device 100 is confirmed through the authentication process, the smart control unit 300 becomes the main switch unlock state, starts the power supply to the USB charger 400, and becomes the main switch on standby state. That is, the main switch knob 31 can be rotated, and the external device connected to the USB charger 400 via the cable can be charged.

[0128] (Process A2) Next, the user rotates the main switch knob 31 to the seat / fuel lock unlock position P3 and presses the switch for unlocking the seat 18 in the seat / fuel lock unlock switch 32. Thus, the lock of the seat 18 is released.

[0129] (Process A3) Then, the user opens the seat 18 and connects the connection terminal 50A of the seat lower housing portion 50 to the user terminal device 100 via the USB cable. Thus, the charging of the user terminal device 100 is started. Then, the user closes the seat 18.

[0130] (Process A4) In a case where the elapsed time in the main switch on standby state exceeds A seconds, the smart control unit 300 determines whether the change condition is satisfied. In this example, the user terminal device 100 is connected to the USB charger 400 before the elapsed time in the main switch on standby state exceeds A seconds. In this regard, the change condition for changing to the simple authentication mode is satisfied, and thus the smart control unit 300 instructs the user terminal device 100 to request the user to select whether to permit the change to the simple authentication mode. Note that, the determination of whether the change condition for changing to the simple authentication mode is satisfied can be performed by the user terminal device 100, and in a case where it is determined that the change condition for changing to the simple authentication mode is satisfied, the user can be requested to select whether to permit the change to the simple authentication mode.

[0131] The user terminal device 100 displays a confirmation screen as illustrated. In the confirmation screen, "Yes" to change to the simple confirmation mode and "No" not to change to the simple confirmation mode are displayed. In a case where the change to the simple authentication mode is selected by the user in the confirmation screen (i.e., in a case where "Yes" is touched), the user terminal device 100 transmits information indicating that the change to the simple authentication mode is selected by the user to the intelligent control unit 300. Then, the intelligent control unit 300 changes the information indicating the set authentication mode from the normal authentication mode to the simple authentication mode.

[0132] Note that, in this case 1, since the user terminal device 100 is connected to the USB charger 400, even if the elapsed time of the main switch on standby state exceeds A seconds, the main switch is in the unlocked state, and the main switch knob 31 is in the rotatable state.

[0133] Then, the elapsed time of the main switch on standby state exceeds B seconds, and thus the intelligent control unit 300 locks the lock of the equipment such as the seat 18 and restricts the output of the engine start permission signal.

[0134] (Process A5) Next, the user performs an operation of pressing the main switch knob 31 in order to perform an operation of instructing the start of the engine 21. Thus, the intelligent control unit 300 performs the authentication processing based on the simple authentication mode. When the authenticity of the user terminal device 100 is confirmed by the authentication processing, the user rotates the main switch knob 31 to the on position P2 and holds the brake lever 29a on the right side of the handlebar 12 to press down the start switch 29, and thus the intelligent control unit 300 outputs the engine start permission signal to start the engine 21.

[0135] Thus, even if the re-authentication is required because the elapsed time of the main switch on standby state exceeds B seconds, since the authentication processing based on the simple authentication mode is performed, the authentication processing based on the ID information can be performed without performing the determination processing of whether the RSSI value is equal to or greater than the set threshold value. Thus, even in a state where the user terminal device 100 is accommodated in the under-seat storage 50, i.e., in a state where the RSSI value becomes small although the user terminal device 100 is in the vicinity (within the authentication area) of the motorized two-wheeled vehicle 11, the undesirable situation that the authentication processing is not performed can be prevented.

[0136] In a case where the authentication processing based on the normal authentication mode is performed in the state of Process A5 as in the past, the authenticity of the user terminal device 100 cannot be confirmed, and thus the lock of the seat 18 cannot be unlocked. Therefore, the user terminal device 100 cannot be taken out. In addition, if the user terminal device 100 cannot be taken out, the re-authentication processing cannot be performed, and thus the engine 21 cannot be started. By changing to the simple authentication mode in advance, such a problem can be solved.

[0137] <Usage Case 2>

[0138] Figure 8 is a diagram for explaining Usage Case 2. Usage Case 2 is an example of a case where the user terminal device 100 is connected to the USB charger 400 after the intelligent control unit 300 becomes the sleep state.

[0139] (Process Bl), (Process B2) are the same as (Process Al), (Process A2) described above, respectively.

[0140] (Process B3) In a case where the user terminal device 100 is not connected to the USB charger 400 and the elapsed time of the main switch-on standby state exceeds A seconds, the intelligent control unit 300 shifts to the sleep state. If the shift to the sleep state is made, the equipment such as the seat 18 is locked, for example, and the output of the engine start permission signal is restricted.

[0141] (Process B4) Next, when the user connects the connection terminal 60A of the front storage portion 60 to the user terminal device 100 via a cable, for example, charging to the user terminal device 100 is started.

[0142] (Process B5) Thus, in a case where the user terminal device 100 is connected to the USB charger 400 after the shift to the sleep state is made, the intelligent control unit 300 determines whether or not the change condition is satisfied. In this example, the user terminal device 100 is connected to the USB charger 400 before the elapsed time of the main switch-on standby state elapses B seconds. In this regard, the change condition to change to the simple authentication mode is satisfied, and therefore, the user terminal device 100 displays a confirmation screen that requires the user to select whether or not to permit the change to the simple authentication mode. In a case where the change to the simple authentication mode is selected by the user in the confirmation screen (i.e., in a case where "Yes" is touched), the user terminal device 100 transmits information indicating that the change to the simple authentication mode is selected by the user to the intelligent control unit 300. Then, the intelligent control unit 300 changes the set authentication mode from the normal authentication mode to the simple authentication mode.

[0143] If the change to the simple authentication mode is made, authentication processing based on the simple authentication mode is performed. In a case where the authenticity of the user terminal device 100 is confirmed, the intelligent control unit 300 unlocks the lock of the equipment such as the seat 18. In addition, the restriction of the engine start permission signal is released.

[0144] (Procedure B6) Next, the user performs an operation of pressing the main switch knob 31 in order to perform an operation of instructing the start of the engine 21, and makes it into the start state, whereby the intelligent control unit 300 sets the equipment such as the seat 18 to be able to be unlocked. Then, the user turns the main switch knob 31 to the on position P2 and holds the brake lever 29a on the right side of the handlebar 12 to press down the start switch 29, whereby the intelligent control unit 300 outputs an engine start permission signal, and the engine 21 is started.

[0145] Thus, even in a state where the user terminal device 100 is housed in the front storage portion 60 after the transition to the sleep state, that is, in a state where the RSSI value becomes small although the user terminal device 100 is in the periphery (in the authentication area) of the motorized two-wheeled vehicle 11, it is possible to prevent such an undesirable situation that the authentication processing is not performed.

[0146] In a case where the authentication processing based on the normal authentication mode is performed in the state of the procedures B5, B6 as in the past, since the authenticity of the user terminal device 100 cannot be confirmed because the RSSI value is lower than the set threshold value, the engine 21 cannot be started, and since the lock of the seat 18 is not unlocked, it is difficult to take out the user terminal device 100. By being set to be able to perform the authentication processing based on the simple authentication mode, it is possible to solve such a problem.

[0147] <Flowchart>

[0148] Figure 9 is a flowchart showing a processing flow of processing (before the start of the engine) based on the intelligent control unit 300. Here, it is assumed that the user terminal device 100 starts the intelligent key application 151 and establishes Bluetooth communication with the intelligent control unit 300 of the motorized two-wheeled vehicle 11.

[0149] The intelligent control unit 300 determines whether or not a request for unlocking is received from the connected user terminal device 100 (step S101). For example, the user terminal device 100 displays a screen for selecting the unlocking of the motorized two-wheeled vehicle 11 on the touch panel TP, and in a case where the unlocking is selected by the user, information indicating the case where the unlocking is selected by the user is transmitted to the intelligent control unit 300.

[0150] In a case where the request for unlocking is not received, the processing is repeated. In a case where the request for unlocking is received, the intelligent control unit 300 performs the authentication processing based on the normal authentication mode (step S103). That is, the intelligent control unit 300 performs the authentication processing based on the ID information received from the user terminal device 100 in a case where the RSSI value is equal to or higher than the threshold value.

[0151] In a case where the authenticity of the user terminal device 100 cannot be confirmed in step S105 (authentication failure), the intelligent control unit 300 determines whether or not a prescribed time (N seconds) has elapsed from the time when the authentication processing based on the normal authentication mode is started (step S107). Before N seconds elapse, the process returns to step S103, and the authentication processing based on the normal authentication mode is repeated.

[0152] On the other hand, in a case where N seconds have elapsed, the process returns to step S101.

[0153] On the other hand, in a case where the authenticity of the user terminal device 100 can be confirmed in step S105 (authentication success), the intelligent control unit 300 sets the on operation of the main switch knob 31 as possible or valid, and becomes the main switch unlocked state (step S109). Next, the intelligent control unit 300 starts the power supply to the USB charger 400 (step S111). The intelligent control unit 300 can also transmit information indicating the start of the power supply to the USB charger 400 to the user terminal device 100.

[0154] Then, the intelligent control unit 300 determines whether or not the main switch 30 is in the on state (step S113). For example, in a case where the main switch knob 31 is turned to the on position P2, the main switch 30 is in the on state, and the processing flow described with reference to FIG. 4 is transitioned to. On the other hand, in a case where the main switch knob 31 is not moved from the off position PI, the main switch 30 is in the off state, and the processing flow described with reference to FIG. 3 is transitioned to. Figure 10 Figure 11

[0155] Figure 10 is a flowchart of the processing flow indicating a case where the main switch 30 is in the on state. The intelligent control unit 300 determines whether or not the user terminal device 100 is in the charging state based on information indicating the charging state received from the user terminal device 100, information indicating the charging state output from the USB charger 400, and the like (step S115). For example, information indicating whether or not the user terminal device 100 is in the charging state is periodically transmitted to the intelligent control unit 300. The USB charger 400 outputs information indicating a case where the charging is started via the cable connection device, a case where the charging is ended, to the intelligent control unit 300. The intelligent control unit 300 determines that the user terminal device 100 is in the charging state in a case where, for example, information indicating a case where the charging is started via the cable connection device is received.

[0156] ​​Not limited thereto, the process of "determining whether the user terminal device 100 is in the charging state" of step S115 can be replaced with a process of determining whether the user terminal device 100 is in the charging state by the USB charger 400 (in the connected state). For example, it can be that, in a case where information indicating that the user terminal device 100 is in the charging state is received and information indicating that the USB charger 400 is in the charging state is received, the intelligent control unit 300 determines that the user terminal device 100 is in the charging state by the USB charger 400. Here, the intelligent control unit 300 can also compare the identification information of the user terminal device 100 received from the user terminal device 100 with the identification information of the device in which the USB charger 400 is in the charging state, and in a case where they are consistent, determine that the user terminal device 100 is in the charging state by the USB charger 400. Not limited thereto, the intelligent control unit 300 can also determine that the user terminal device 100 is in the charging state by the USB charger 400 in a case where the deviation of the timing of the start of charging received from the user terminal device 100 and the timing of the start of charging output from the USB charger 400 is within a prescribed time difference. Note that the same can also apply to the process of "determining whether the user terminal device 100 is in the charging state" in the following description.

[0157] In a case where information indicating the situation in which the user terminal device 100 is in the charging state is received in step S115, the intelligent control unit 300 determines whether there is a reply from the user regarding the change to the easy authentication mode based on the information received from the user terminal device 100 (step S117). For example, in a case where information indicating the situation in which "Yes" or "No" was touched in the above-described confirmation screen is not received, the intelligent control unit 300 determines that there is no reply from the user regarding the change to the easy authentication mode.

[0158] For example, a case in which the user has not replied in the confirmation screen for a prescribed time or more is equivalent thereto.

[0159] In the case where no reply from the user regarding the change to the simple authentication mode is received, the intelligent control unit 300 determines whether or not an operation to instruct the start of the engine 21 is accepted (step S119). In the case where an operation to instruct the start of the engine 21 is accepted, the intelligent control unit 300 performs a notification process to the user (step S121). For example, the intelligent control unit 300 transmits information indicating that the engine start permission signal cannot be output due to the absence of a reply from the user regarding the change to the simple authentication mode, and causes the information to be displayed on the user terminal device 100. In this notification process, a message urging a reply from the user regarding the change to the simple authentication mode can also be displayed on the user terminal device 100. Thereafter, the intelligent control unit 300 returns to step S115 and repeats the process.

[0160] On the other hand, in the case where it is determined in step S117 that there is a reply from the user regarding the change to the simple authentication mode, it is determined whether or not the reply is "select the change to the simple authentication mode" (step S123). In the case where the reply is "select the change to the simple authentication mode", the intelligent control unit 300 determines whether or not an operation to instruct the start of the engine 21 is accepted (step S125). In the case where an operation to instruct the start of the engine 21 is accepted, the intelligent control unit 300 performs an authentication process based on the simple authentication mode (step S127). Note that the intelligent control unit 300 changes the set authentication mode from the normal authentication mode to the simple authentication mode while performing the authentication process based on the simple authentication mode.

[0161] In the case where the authenticity of the user terminal device 100 is confirmed in step S129 (authentication success), the intelligent control unit 300 outputs an engine start permission signal to the ECU 40 to start the engine 21 (step S131). On the other hand, in the case where the authenticity of the user terminal device 100 is not confirmed in step S129 (authentication failure), or in the case where no operation to instruct the start of the engine is accepted, the intelligent control unit 300 returns to step S115 and repeats the process.

[0162] Returning to step S115, in the case where information indicating that the user terminal device 100 is in the charging state is not received, or in the case where the reply is not "select the change to the simple authentication mode" in step S117, the intelligent control unit 300 determines whether or not an operation to instruct the start of the engine 21 is accepted (step S133). In the case where an operation to instruct the start of the engine 21 is accepted, the intelligent control unit 300 performs an authentication process based on the normal authentication mode (step S135).

[0163] When the authenticity of the user terminal device 100 is confirmed in step S137 (authentication success), the intelligent control unit 300 outputs an engine start permission signal to the ECU 40 to start the engine 21 (step S131). On the other hand, when the authenticity of the user terminal device 100 is not confirmed in step S137 (authentication failure), the intelligent control unit 300 returns to step S115 to repeat the process.

[0164] Thus, in a case where the user terminal device 100 connected by wire is charged by the USB charger 400, it is presumed that the user is present in the vicinity of the motorcycle 11. Therefore, in a case where the start of the engine 21 is instructed, the process based on the normal authentication mode is not executed, but the authenticity of the user terminal device 100 is confirmed by the authentication process based on the easy authentication mode, whereby the engine start permission signal is output. On the other hand, in a case where the user terminal device 100 is not in a charging state, a device (for example, a mobile storage battery) other than the user terminal device 100 is connected by wire and charged by the USB charger 400, or the like, it is presumed that the user is away from the motorcycle 11. Therefore, in a case where the start of the engine 21 is instructed, the engine start permission signal is output after the authentication process is executed again. Thus, in a case where the user terminal device 100 is not connected to the USB charger 400, the authentication process is executed again, whereby it is possible to prevent a person other than the rightful user from starting the engine 21.

[0165] In addition, in a case where the user terminal device 100 is in a charging state but is not in a state of being charged by the USB charger 400, when the start of the engine 21 is instructed, the notification process is executed without outputting the engine start permission signal.

[0166] Figure 11 is a flowchart of a process flow indicating a case where the main switch 30 is not in an on state. The intelligent control unit 300 determines whether or not the period of the main switch on standby state has reached A seconds (step S141). The start of the period of the main switch on standby state is, for example, the time when it is determined that the authentication is successful. In a case where the period of the main switch on standby state has not reached A seconds, the process returns to step S113 to be repeated.

[0167] In a case where the period of the main switch on standby state has reached A seconds, the intelligent control unit 300 determines whether or not the user terminal device 100 is in a charging state based on the information indicating the charging state received from the user terminal device 100 (step S143). In a case where the information indicating that the user terminal device 100 is in a charging state is received, the intelligent control unit 300 determines whether or not there is a reply from the user regarding the change to the easy authentication mode based on the information received from the user terminal device 100 (step S145).

[0168] In the case where a reply from the user regarding the change to the simple authentication mode is present, it is determined whether the reply is "select change to simple authentication mode" (step S147). In the case where the reply is not "select change to simple authentication mode", the intelligent control unit 300 stops the supply of power to the USB charger 400 (step S149), performs a lock-up process (step S151), restricts the output of the engine start permission signal (step S153), and ends the process. The unlock process is a process of controlling the electromagnetic lock 70 so as to make possible the unlocking operation of the equipment of the handle lock mechanism 28, the seat 18, the fuel cap 24, the main switch knob 31, and the like.

[0169] Thus, in the case where the user terminal device 100 is in a state of being charged but not charged in a wired connection manner by the USB charger 400, it is presumed that the possibility of the user leaving the motor scooter 11 is high, and thus the lock-up process and the like are executed as a condition in the case where the main switch on wait state has elapsed for A seconds. Thus, the theft prevention can be ensured.

[0170] In the case where the information indicating that the user terminal device 100 is in a state of being charged is not received in step S143, or in the case where there is no reply from the user regarding the change to the simple authentication mode in step S145, the intelligent control unit 300 shifts to the process described with reference to Figure 12 the flowchart of FIG. 16.

[0171] On the other hand, in the case where it is determined that the reply is "select change to simple authentication mode" in step S147, the intelligent control unit 300 determines whether the period of the main switch on wait state has reached B seconds (step S155). In the case where the period of the main switch on wait state has reached B seconds, the intelligent control unit 300 proceeds to step S149. On the other hand, in the case where the period of the main switch on wait state has not reached B seconds, the intelligent control unit 300 returns to step S113.

[0172] Figure 12 is a flowchart of a part of the flow of the process in the case where the main switch on wait state has exceeded A seconds. In the case where the information indicating that the user terminal device 100 is in a state of being charged is not received in step S143, or in the case where there is no reply from the user regarding the change to the simple authentication mode in step S145, the intelligent control unit 300 performs a lock-up process (step S161), and restricts the output of the engine start permission signal (step S163). Note that, in the lock-up process of step S161, the lock-up of the main switch knob 31 is performed, and the main switch unlock state is maintained.

[0173] Next, the intelligent control unit 300 determines whether or not the period of the main switch on waiting state has reached B seconds (step S165). In the case where the period of the main switch on waiting state has reached B seconds, the intelligent control unit 300 becomes the main switch lock state, stops the power supply to the USB charger 400 (step S167), and ends the process.

[0174] In the case where it is determined in step S165 that the period of the main switch on waiting state has not reached B seconds, the intelligent control unit 300 determines whether or not the user terminal device 100 is in the charging state on the basis of the information indicating the charging state received from the user terminal device 100 (step S169). In the case where information indicating that the user terminal device 100 is in the charging state is received, the intelligent control unit 300 determines whether or not there is a reply from the user with respect to the change to the simple authentication mode on the basis of the information received from the user terminal device 100 (step S171).

[0175] In the case where there is a reply from the user with respect to the change to the simple authentication mode, it is determined whether or not the reply is "select the change to the simple authentication mode" (step S173). In the case where the reply is not "select the change to the simple authentication mode", the intelligent control unit 300 moves to step S167, becomes the main switch lock state, stops the power supply to the USB charger 400, and ends the process.

[0176] On the other hand, in the case where it is determined in step S173 that the reply is "select the change to the simple authentication mode", the intelligent control unit 300 performs the authentication process based on the simple authentication mode (step S175). Note that the intelligent control unit 300 changes the authentication mode from the normal authentication mode to the simple authentication mode at the same time as performing the authentication process based on the simple authentication mode. In the case where the authenticity of the user terminal device 100 is confirmed in step S177 (authentication success), the intelligent control unit 300 makes the on operation of the main switch knob 31 possible or valid, becomes the main switch unlock state (step S179), and moves to the process of step S113. On the other hand, in the case where the authenticity of the user terminal device 100 is not confirmed in step S129 (authentication failure), the intelligent control unit 300 does not become the main switch unlock state, but moves to the process of step S113.

[0177] Figure 13 is a flowchart showing the flow of the process performed by the intelligent control unit 300 (after the main switch is turned off). Here, the user terminal device 100 starts the smart key application 151 and establishes the Bluetooth communication with the intelligent control unit 300 of the motorcycle 11. In addition, the state at the start of the process can be that the intelligent control unit 300 is in the main switch on waiting state, or that the engine is being started.

[0178] The intelligent control unit 300 determines whether the main switch 30 is in the off state (step S201). In the case where the main switch 30 is in the off state, the intelligent control unit 300 outputs an engine stop permission signal (step S203), determines whether the user terminal device 100 is in the charging state based on the information indicating the charging state received from the user terminal device 100 (step S205).

[0179] In the case where the user terminal device 100 is in the charging state, the intelligent control unit 300 determines whether there is a reply from the user regarding the change to the simple authentication mode based on the information received from the user terminal device 100 (step S207).

[0180] In the case where there is no reply from the user regarding the change to the simple authentication mode, the intelligent control unit 300 determines whether the period of the main switch on standby state has reached B seconds (step S209). The period of the main switch on standby state here includes, in addition to the period described above, a period with the time point after the start of the engine 21 as a starting point, which is the time point at which the main switch 30 is turned off by the operation of instructing the stop of the engine 21 (for example, the operation of locating the main switch knob 31 at the off position PI) after the start of the engine 21.

[0181] In the case where it is determined in step S209 that the period of the main switch on standby state has not reached B seconds, the intelligent control unit 300 returns to the process of determining the charging state of the user terminal device 100 in step S205.

[0182] On the other hand, in the case where the period of the main switch on standby state has reached B seconds, the intelligent control unit 300 stops the power supply to the USB charger 400 (step S211), and performs the lockup process (step S213).

[0183] Returning to step S207, in the case where there is a reply from the user regarding the change to the simple authentication mode, the intelligent control unit 300 determines whether the reply is "select the change to the simple authentication mode" (step S215). In the case where the reply is "select the change to the simple authentication mode", the intelligent control unit 300 moves to step S209, and determines whether the period of the main switch on standby state has reached B seconds.

[0184] On the other hand, if it is determined in step S215 that the response is not "selecting to change to simplified authentication mode", the intelligent control unit 300 determines whether the main switch on-wait state period has reached A seconds (step S217). The main switch on-wait state period here also includes the period starting from the moment when the main switch 30 is turned off by an operation that instructs the engine 21 to stop after starting the engine 21 (e.g., an operation that places the main switch knob 31 in the off position P1). It should be noted that if no information indicating that the user terminal device 100 is in a charging state is received in step S205, the process also proceeds to step S217.

[0185] In step S217, if the elapsed period of the main switch on-wait state reaches A seconds, the intelligent control unit 300 stops supplying power to the USB charger 400 (step S211), performs a locking process (step S213), and ends the process. On the other hand, if the elapsed period of the main switch on-wait state does not reach A seconds, the intelligent control unit 300 sends a signal to the reference... Figure 14 The explanation of the processing change.

[0186] Figure 14 It means in Figure 13 The flowchart shows the processing flow for the case where a negative determination is made in step S217. The intelligent control unit 300 determines whether the main switch knob 31 has been short-pressed (step S219). A short-press operation of the main switch knob 31 refers to an operation that does not involve pressing for several seconds like a long press, but rather an operation that pushes the main switch knob 31 in for a short time, indicating that the disconnection process of the main switch 30 should be ended immediately.

[0187] When the main switch knob 31 is briefly pressed, the intelligent control unit 300 stops supplying power to the USB charger 400 (step S221), performs a locking process (step S223), and ends the process.

[0188] In step S219, if the main switch knob 31 is not briefly pressed, the intelligent control unit 300 determines whether to continue Bluetooth communication with the user terminal device 100 (step S225). If Bluetooth communication with the user terminal device 100 is not continued, it is presumed that the user holding the user terminal device 100 has left the motorized two-wheeled vehicle 11, and therefore the intelligent control unit 300 moves to the processing of step S221.

[0189] On the other hand, in the case where the Bluetooth communication with the user terminal device 100 is continued in the determination in step S225, the intelligent control unit 300 executes a lock confirmation process (step S227). The lock confirmation process is a process of confirming to the user whether or not to lock the equipment (including the handle lock mechanism 28, the fuel cap 24, and the like) immediately. In this case, it is possible to register in advance by the user whether or not to lock the above-mentioned equipment, or it is possible to cause the user terminal device 100 to display a confirmation screen at this timing for the user to select.

[0190] Then, the intelligent control unit 300 determines whether or not to lock the equipment such as the seat 18 immediately (step S229). In the case where the equipment such as the seat 18 is locked immediately, the intelligent control unit 300 moves to the process of step S221. On the other hand, in the case where the equipment such as the seat 18 is not locked immediately, the intelligent control unit 300 returns to the process of step S205.

[0191] Figure 15 is a flowchart of a process flow (one) for executing an authentication process based on a simple authentication mode. In the process flow (one), the intelligent control unit 300 decides a display timing of a confirmation screen for changing to the simple authentication mode.

[0192] First, the intelligent control unit 300 determines whether or not a change condition for changing to the simple authentication mode is satisfied at a prescribed change timing (step S301). The change timing is a scenario in which it is necessary to change to the simple authentication mode, and includes, for example, (1) a case where the user terminal device 100 is connected to the USB charger 400 in a wired manner in a charging state before the elapse of A seconds in the main switch on-waiting state; (2) a case where the user terminal device 100 is connected to the USB charger 400 in a wired manner in a charging state after the elapse of A seconds and before the elapse of B seconds in the main switch on-waiting state; and (3) a case where the user terminal device 100 is connected to the USB charger 400 in a wired manner in a charging state before the elapse of B seconds in the main switch on-waiting state after the main switch 30 becomes the on state and then becomes the off state.

[0193] In the case where the change condition for changing to the simple authentication mode is satisfied, the intelligent control unit 300 instructs the user terminal device 100 to request the user to select whether or not to permit the change to the simple authentication mode (step S303).

[0194] Next, the user terminal device 100 displays the above-mentioned confirmation screen on the touch panel TP in accordance with an instruction from the intelligent control unit 300 (step S305), and determines which selection is made by the user (step S307). In a case where the change to the simple authentication mode is selected by the user in the confirmation screen (i.e., in a case where "Yes" is touched), the user terminal device 100 transmits information indicating that the change to the simple authentication mode is selected by the user to the intelligent control unit 300 (step S309).

[0195] On the other hand, the intelligent control unit 300 determines whether or not the information indicating that the change to the simple authentication mode is selected by the user is received (step S311). In a case where the information indicating that the change to the simple authentication mode is selected by the user is received, the intelligent control unit 300 changes the information indicating the set authentication mode from the normal authentication mode to the simple authentication mode (step S313). That is, the intelligent control unit 300 saves the information indicating that the simple authentication mode is set as the set authentication mode information 351 in the storage section 350.

[0196] Figure 16 is a flowchart indicating a processing flow (two) for performing the authentication processing based on the simple authentication mode. In the processing flow (two), the user terminal device 100 determines a display timing of a confirmation screen for confirming the change to the simple authentication mode.

[0197] First, the intelligent control unit 300 periodically transmits state information to the user terminal device 100 (step S331). The state information includes, for example, "the terminal connected to the USB charger 400 via the USB port is the user terminal device 100", the main switch on waiting state, the main switch 30 becomes the on state, the main switch 30 becomes the off state, the elapsed time of the main switch on waiting state, and the like.

[0198] The user terminal device 100 determines whether or not the state information is received from the intelligent control unit 300 (step S333). In a case where the state information is received, the user terminal device 100 updates the storage section 150 based on the received state information (step S335). Next, the user terminal device 100 determines whether or not the communication with the intelligent control unit 300 is cut off (step S337).

[0199] In a case where the communication with the smart control unit 300 is cut off, it is determined whether the change condition for the change to the simple authentication mode under the prescribed change timing is satisfied with reference to the storage section 150 (step S339). The change timing includes, for example, (2) a case where the main switch is in the on-waiting state and the user terminal device 100 is connected to the USB charger 400 in a wired manner and is in the charging state after the elapse of A seconds and before the elapse of B seconds from the elapse of the time in the on-waiting state of the main switch. Not limited thereto, the above-described change timings (1), (3) can also be included.

[0200] In a case where the change condition for the change to the simple authentication mode under the prescribed change timing is satisfied, the user terminal device 100 displays the above-described confirmation screen on the touch panel TP (step S341), and determines which selection by the user is made (step S343). In the confirmation screen, in a case where the change to the simple authentication mode is selected by the user (i.e., in a case where "Yes" is touched), the user terminal device 100 starts the communication with the smart control unit 300 (step S345), and transmits information indicating that the change to the simple authentication mode is selected by the user to the smart control unit 300 (step S347).

[0201] On the other hand, the smart control unit 300 determines whether the information indicating that the change to the simple authentication mode is selected by the user is received (step S349). In a case where the information indicating that the change to the simple authentication mode is selected by the user is received, the smart control unit 300 changes the information indicating the set authentication mode from the normal authentication mode to the simple authentication mode (step S351). That is, the smart control unit 300 saves the information indicating that the simple authentication mode is set as the set authentication mode information 351 in the storage section 350.

[0202] Figure 17 is a flowchart indicating a processing flow (No. 3) for performing the authentication processing based on the simple authentication mode. The present processing flow (No. 3) is another example of the processing flow (e.g., No. 2) in which the user terminal device 100 determines the display timing of the confirmation screen for the change to the simple authentication mode.

[0203] First, the intelligent control unit 300 periodically transmits the state information to the user terminal device 100 (step S361). The user terminal device 100 determines whether to start the power supply to the USB charger 400 based on the state information received from the intelligent control unit 300 (step S363). In the case of starting the power supply to the USB charger 400, the user terminal device 100 determines whether to connect with the USB charger 400 (step S365). For example, the user terminal device 100 displays an input screen by which the user inputs whether to connect with the USB charger 400, and in the case where the user selects to connect with the USB charger 400 via the input screen, the user terminal device 100 determines to connect with the USB charger 400. In the case of connecting with the USB charger 400, the user terminal device 100 determines whether the user terminal device 100 is in the charging state (step S367).

[0204] In the case where the user terminal device 100 is in the charging state, the user terminal device 100 displays the above-described confirmation screen on the touch panel TP in accordance with the instruction from the intelligent control unit 300 (step S369), and determines which selection the user makes (step S371). In the case where the user selects to change to the simple authentication mode in the confirmation screen (i.e., in the case of touching "Yes"), the user terminal device 100 transmits information indicating the intention to the intelligent control unit 300 (step S373).

[0205] Next, the intelligent control unit 300 determines whether to receive the information indicating that the user selects to change to the simple authentication mode (step S375). In the case of receiving the information indicating that the user selects to change to the simple authentication mode, the intelligent control unit 300 determines whether it is immediately before the process of becoming the target of the simple authentication mode (step S377). Note that the process of becoming the target of the simple authentication mode is determined in advance from the viewpoint of theft prevention.

[0206] In the case of being immediately before the process of becoming the target of the simple authentication mode, the intelligent control unit 300 performs the authentication process based on the simple authentication mode (step S379). Note that in step S379, the intelligent control unit 300 can also change the information indicating the set authentication mode from the normal authentication mode to the simple authentication mode.

[0207] According to the above-described embodiment, there are provided an antenna mounted on a vehicle and communicating with a user terminal device existing in a communication area around the vehicle, a processing section that executes authentication processing when an authentication execution condition that a signal intensity of a signal communicated with the user terminal device via the antenna is equal to or higher than a threshold value is satisfied, and an acquisition section that acquires information indicating a state of the user terminal device with respect to the vehicle, wherein the processing section executes the authentication processing regardless of whether or not the authentication execution condition is satisfied when it is determined based on the information acquired by the acquisition section that a change condition is satisfied, whereby it is possible to prevent an undesirable situation in which authentication processing based on the on-vehicle device is not executed.

[0208] The above-described embodiments are illustrative of the manner in which the present application is implemented, but the present application is not limited at all by such embodiments, and various modifications and substitutions can be made within the scope of the present application without departing from the spirit of the present application.

[0209] Note that the present application is not limited to the above-described embodiments, and for example, the system is not limited to being applied to a motorized two-wheeled vehicle, and can be widely applied to straddle-type vehicles. The straddle-type vehicles include all vehicles in which a driver straddles a vehicle body to ride the vehicle, and include not only motorized two-wheeled vehicles (including bicycles with a prime mover and small motorcycle-type vehicles), but also vehicles with three wheels (including vehicles with two front wheels and one rear wheel, in addition to vehicles with one front wheel and two rear wheels) or four wheels. In addition, vehicles including an electric motor in the prime mover are also included. In addition, the system can also be applied to a motor vehicle having a vehicle cabin. In addition, the system can also be applied to various devices that require communication, in addition to vehicles. For example, the system can be applied to devices such as a storage box, a bag, and the like, that have a communication function.

[0210] Note that the intelligent control section 300 can also change the set authentication mode from the simple authentication mode to the normal authentication mode in a case where it is detected that the connection of the user terminal device 100 to the USB charger 400 is released, in a case where it is detected that the charging of the user terminal device 100 is completed, or in a case where the user terminal device 100 selects not to change to the simple authentication mode in the confirmation screen. Note that the change to the simple authentication mode can also be limited to only once, without being limited thereto. For example, in a case where the change to the simple authentication mode is executed, the mode change can not be maintained, and it can be confirmed every time whether or not the change condition is satisfied, and in a case where the change condition is satisfied again, the simple authentication mode is executed.
