Description

[Technical field]

[0001] The present invention relates to a program, a saddle-type vehicle, and a system for detecting and reporting a rollover of a saddle-type vehicle. [Background technology]

[0002] There is a known technology for detecting a rollover of the vehicle body and automatically reporting it in a saddle-type vehicle. Patent Document 1 proposes a technology related to a cancel switch that can cancel the report when a rollover occurs and reporting is not necessary. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] International Publication No. 2018 / 225427 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above conventional technology, the fall of the body is detected by the sensor on the motorcycle and reported by the communication unit, but if a communication unit is incorporated in the motorcycle, the motorcycle itself needs to be equipped with a communication function that can report, which poses the issue of costs such as monthly fees for that communication.On the other hand, if the motorcycle is not equipped with a reporting function, the issue becomes how to more accurately detect the fall of the motorcycle in the external device that reports.

[0005] An object of the present invention is to preferably detect a fall of a saddle riding type vehicle by a portable terminal. Another object is to preferably detect a fall even if the communication connection between the portable terminal carried by the rider and the saddle riding type vehicle is cut off when the saddle riding type vehicle falls. [Means for solving the problem]

[0006] According to the present invention, there is provided a program for causing a computer to execute each step of a control method for a mobile terminal having a first communication means for performing short-range wireless communication with a saddle-riding vehicle, a second communication means for communicating with an external device, and an acceleration sensor, the control method including a receiving step of receiving information from the saddle-riding vehicle via the first communication means, a comparison step of comparing the acceleration of the saddle-riding vehicle included in the information from the saddle-riding vehicle with the acceleration acquired by the acceleration sensor of the mobile terminal to determine whether a significant difference has occurred when a significant difference has occurred in the comparison step, and a fall determination step of determining that the saddle-riding vehicle has fallen over.

[0007] According to the present invention, there is provided a saddle-type vehicle comprising: communication means for establishing short-range wireless communication with a portable terminal when the saddle-type vehicle is started; rollover detection means for detecting a rollover of the saddle-type vehicle in accordance with a degree of inclination of the vehicle and outputting a signal; vehicle speed detection means for detecting a vehicle speed of the saddle-type vehicle; and control means for notifying the portable terminal of a signal by the communication means in response to input of the signal from the rollover detection means and for periodically notifying the portable terminal of an output from the vehicle speed detection means by the communication means. In the mobile terminal, the acceleration of the saddle riding type vehicle included in the information notified from the saddle riding type vehicle is compared with the acceleration acquired by an acceleration sensor of the mobile terminal to determine whether or not a significant difference occurs, and if a significant difference occurs, it is determined that the saddle riding type vehicle has fallen over. It is characterized by:

[0008] According to the present invention, there is also provided a system including a saddle-riding type vehicle, a mobile terminal, and an external device, wherein the mobile terminal comprises first communication means for performing short-range wireless communication with the saddle-riding type vehicle, second communication means for communicating with the external device, an acceleration sensor, receiving means for receiving information from the saddle-riding type vehicle via the first communication means, comparison means for comparing an acceleration of the saddle-riding type vehicle included in the information from the saddle-riding type vehicle with an acceleration acquired by an acceleration sensor of the mobile terminal to determine whether a significant difference exists when a moving speed of the saddle-riding type vehicle included in the information about the saddle-riding type vehicle is equal to or higher than a predetermined value, and fall determination means for determining that the saddle-riding type vehicle has fallen over based on the determination by the comparison means that a significant difference exists, and the saddle-riding type vehicle comprises third communication means for establishing short-range wireless communication with the mobile terminal when the saddle-riding type vehicle is started, vehicle speed detection means for detecting a vehicle speed of the saddle-riding type vehicle, and control means for periodically notifying the mobile terminal of an output from the vehicle speed detection means by the third communication means. Effect of the Invention

[0009] According to the present invention, the mobile terminal can determine a fall and automatically send a notification to a preset contact. Furthermore, even if the communication connection between the mobile terminal carried by the rider and the saddle riding type vehicle is cut off when the saddle riding type vehicle falls, the notification can be sent appropriately.

[0011] Hereinafter, the embodiments will be described in detail with reference to the accompanying drawings. Note that the following embodiments do not limit the invention according to the claims, and not all combinations of features described in the embodiments are essential to the invention. Two or more features among the multiple features described in the embodiments may be arbitrarily combined. In addition, the same reference numbers are used for the same or similar configurations, and duplicated descriptions are omitted.

[0012] In each figure, arrows X, Y, and Z indicate directions perpendicular to each other, with the X direction indicating the front-to-rear direction of the saddle riding type vehicle, the Y direction indicating the width direction (left-to-right direction) of the saddle riding type vehicle, and the Z direction indicating the up-to-down direction. The left and right of the saddle riding type vehicle are the left and right when viewed in the forward direction. Hereinafter, the front or rear in the front-to-rear direction of the saddle riding type vehicle may be simply referred to as the front or rear. Also, the inside or outside of the vehicle width direction (left-to-right direction) of the saddle riding type vehicle may be simply referred to as the inside or outside.

[0013] <First embodiment> <Overall configuration of the reporting system> A first embodiment of the present invention will be described below. Fig. 1 is a diagram showing the overall configuration of a reporting system according to this embodiment. This system includes a saddle-type vehicle 100, a mobile terminal 200, external devices 300 and 400, and a wearable terminal 500. Note that this is not intended to limit the present invention, and other devices may also be included.

[0014] In this system, when the saddle riding vehicle 100 is detected to have fallen over, the mobile terminal 200 carried by the rider of the saddle riding vehicle 100 collects various information and reports the information to predetermined contacts, for example, emergency contacts (119), a mobile terminal of an acquaintance, an external device such as an information storage server, via broadband wireless communication such as mobile communication (4G, 5G). These predetermined contacts can be set in advance. The external device 300 indicates the mobile terminal of an acquaintance set as the predetermined contact, and the external device 400 indicates, for example, a terminal of a fire station or a terminal of a hospital connected by calling 119.

[0015] The mobile terminal 200 receives the detection result of the fall detection sensor 102 provided on the saddle riding type vehicle 100 by short-range wireless communication (here, Bluetooth communication) via the Bluetooth (registered trademark) unit 103, and judges the fall of the saddle riding type vehicle 100. Furthermore, the mobile terminal 200 periodically or irregularly receives information about the vehicle speed from the saddle riding type vehicle 100, as will be described in detail later. This information about the vehicle body is used to judge whether a significant difference has occurred compared with the vehicle speed judged by the sensor provided on the mobile terminal 200. For example, if the rider and the saddle riding type vehicle 100 are physically separated when a fall occurs, the short-range wireless communication between the mobile terminal 200 and the saddle riding type vehicle 100 may be cut off, and in that case, there is a risk that the detection result of the fall detection sensor 102 cannot be received by the mobile terminal 200. Even in such a scene, the detection of the fall is judged by judging the significant difference. When it is determined that a fall has occurred, the mobile terminal 200 acquires various information from the saddle riding vehicle 100, the wearable terminal 500, and the mobile terminal 200 itself, and notifies a predetermined contact of the fact that the rider has fallen and the acquired information. The wearable terminal 500 is a smart watch or the like worn by the rider of the saddle riding vehicle 100, and can detect biological information such as the rider's heart rate, blood pressure, electrocardiogram, and blood oxygen level, and transmits the detected biological information to the mobile terminal 200 by short-range wireless communication (for example, Bluetooth communication).

[0016] In this manner, in this system, the mobile terminal 200 collects various information, determines that the saddle riding vehicle 100 has fallen over, and reports the occurrence via wideband wireless communication. This makes it possible to preferably report the occurrence without the need to provide a separate unit for wideband wireless communication in the saddle riding vehicle 100. Furthermore, according to this embodiment, even if the rider is thrown away from the saddle riding vehicle 100 during a fall and becomes separated from it, causing short-range wireless communication between the mobile terminal 200 and the saddle riding vehicle 100 to be cut off, the mobile terminal 200 can preferably determine that the saddle riding vehicle has fallen over.

[0017] <Overview of saddle-type vehicles> FIG. 2 is a right side view of the saddle riding type vehicle 100 according to one embodiment of the present invention, and FIG.

[0018] The saddle-type vehicle 100 is a touring motorcycle suitable for long-distance travel, but the present invention is applicable to various saddle-type vehicles including other types of motorcycles, and is also applicable to electric vehicles using a motor as a drive source, in addition to vehicles using an internal combustion engine as a drive source. Hereinafter, the saddle-type vehicle 100 may be referred to as vehicle 100. Furthermore, in this embodiment, a two-wheeled saddle-type vehicle will be described as an example of a vehicle, but this is not intended to limit the present invention, and the present invention can be applied to various vehicles, such as four-wheel drive vehicles.

[0019] The vehicle 100 is equipped with a power unit 2 between the front wheels FW and the rear wheels RW. In this embodiment, the power unit 2 includes a horizontally opposed six-cylinder engine 21 and a transmission 22. The driving force of the transmission 22 is transmitted to the rear wheels RW via a drive shaft (not shown), thereby rotating the rear wheels RW.

[0020] The power unit 2 is supported by a body frame 3. The body frame 3 includes a pair of left and right main frames 31 extending in the X direction. A fuel tank 5 and an air cleaner box (not shown) are disposed above the main frames 31. A meter panel MP equipped with an electronic image display device and the like that displays various information to the rider is provided in front of the fuel tank 5.

[0021] A head pipe 32 is provided at the front end of the main frame 31, which rotatably supports a steering shaft (not shown) that is turned by the handlebars 8. A pair of left and right pivot plates 33 is provided at the rear end of the main frame 31. The lower ends of the pivot plates 33 and the front end of the main frame 31 are connected by a pair of left and right lower arms (not shown), and the power unit 2 is supported by the main frame 31 and the lower arms. A pair of left and right seat rails (not shown) extending rearward are also provided at the rear end of the main frame 31, and the seat rails support a seat 4a on which a rider sits, a seat 4b on which a passenger sits, a rear trunk 7b, etc.

[0022] A front end of a rear swing arm (not shown) extending in the front-rear direction is supported so as to be freely swingable by the pivot plate 33. The rear swing arm is capable of swinging in the vertical direction, and a rear wheel RW is supported at its rear end. An exhaust muffler 6 for silencing exhaust from the engine 21 is provided extending in the X direction on the side of the lower part of the rear wheel RW. Left and right saddlebags 7a are provided on the side of the upper part of the rear wheel RW.

[0023] A front suspension mechanism 9 that supports a front wheel FW is provided at the front end of the main frame 31. The front suspension mechanism 9 includes an upper link 91, a lower link 92, a fork support 93, a cushion unit 94, and a pair of left and right front forks 95.

[0024] The upper link 91 and the lower link 92 are disposed vertically at a distance from each other on the front end of the main frame 31. The rear ends of the upper link 91 and the lower link 92 are pivotally connected to supports 31a, 31b provided on the front end of the main frame 31. The front ends of the upper link 91 and the lower link 92 are pivotally connected to a fork support 93. The upper link 91 and the lower link 92 each extend in the fore-and-aft direction and are disposed substantially parallel to each other.

[0025] The cushion unit 94 has a structure in which a shock absorber is inserted into a coil spring, and its upper end is supported so as to be able to swing freely by the main frame 31. The cushion unit 94 has a lower end supported so as to be able to swing freely by the lower link 92.

[0026] The fork support 93 is cylindrical and inclined backward. A front end of an upper link 91 is rotatably connected to an upper front portion of the fork support 93. A front end of a lower link 92 is rotatably connected to a lower rear portion of the fork support 93.

[0027] A steering shaft 96 is supported by the fork support 93 so as to be rotatable about its axis. The steering shaft 96 has an axis (not shown) that passes through the fork support 93. A bridge (not shown) is provided at the lower end of the steering shaft 96, and a pair of left and right front forks 95 are supported by this bridge. The front wheel FW is rotatably supported by the front forks 95. The upper end of the steering shaft 96 is connected via a link 97 to a steering shaft (not shown) that is rotated by the handlebars 8. The steering shaft 96 rotates when the handlebars 8 is steered, and the front wheel FW is steered.

[0028] The vehicle 100 includes a braking device 19F for braking the front wheel FW and a braking device 19R for braking the rear wheel RW. The braking devices 19F and 19R are configured to be operable by the rider's operation of the brake lever 8a or the brake pedal 8b. The braking devices 19F and 19R are, for example, disc brakes. When there is no need to distinguish between the braking devices 19F and 19R, they are collectively referred to as the braking devices 19.

[0029] A headlight 11 that irradiates light ahead of the vehicle 100 is disposed at the front of the vehicle 100. The headlight 11 of this embodiment is a twin-lens type headlight unit that is provided with a right light irradiation section 11R and a left light irradiation section 11L in a symmetrical manner. However, a single-lens type or triple-lens type headlight unit, or an asymmetric twin-lens type headlight unit may also be used.

[0030] The front of the vehicle 100 is covered with a front cowl 12, and the front sides of the vehicle 100 are covered with a pair of left and right side cowls 14. A screen 13 is disposed above the front cowl 12. The screen 13 is a windshield that reduces the wind pressure experienced by the rider while riding, and is formed, for example, from a transparent resin member.

[0031] A pair of left and right side mirror units 15 are disposed on the sides of the front cowl 12. The side mirror units 15 support side mirrors (not shown) that enable the rider to view the rear.

[0032] In this embodiment, the front cowl 12 is made up of cowl members 121 to 123. The cowl member 121 extends in the Y direction and makes up the main body of the front cowl 12, and the cowl member 122 makes up an upper portion of the cowl member 121. The cowl member 123 is disposed spaced apart from the cowl member 121 in the downward direction.

[0033] An opening for exposing the headlight 11 is formed between the cowl member 121 and the cowl member 123 and between the pair of left and right side cowls 14, and the upper edge of this opening is defined by the cowl member 121, the lower edge is defined by the cowl member 123, and the left and right side edges are defined by the side cowls 14.

[0034] An imaging unit 16A and a radar unit 16B are disposed behind the front cowl 12 as detection devices for detecting the situation ahead of the vehicle 100. The radar unit 16B is, for example, a millimeter wave radar. The imaging unit 16A includes an imaging element such as a CCD image sensor or a CMOS image sensor, and an optical system such as a lens, and captures an image ahead of the vehicle 100. The imaging unit 16A is disposed behind a cowl member 122 that constitutes the upper part of the front cowl 12. The cowl member 122 is formed with an opening 122a penetrating therethrough, and the imaging unit 16A captures an image ahead of the vehicle 100 through the opening 122a.

[0035] The radar unit 16B is disposed behind the cowl member 121. The presence of the cowl member 121 makes the presence of the detection unit (external environment monitoring device) 16 less noticeable when viewed from the front of the vehicle 100, thereby preventing the deterioration of the appearance of the vehicle 100. The cowl member 121 is made of a material, such as resin, that allows electromagnetic waves to pass through.

[0036] The imaging unit 16A and the radar unit 16B are disposed in the center of the front cowl 12 in the Y direction when viewed from the front of the vehicle. By disposing the imaging unit 16A and the radar unit 16B in the center of the vehicle 100 in the Y direction, a wider imaging range and detection range can be obtained on the left and right sides of the front of the vehicle 100, and the situation ahead of the vehicle 100 can be detected more accurately. In addition, since the front of the vehicle 100 can be monitored evenly on the left and right sides with one imaging unit 16A and one radar unit 16B, it is particularly advantageous to provide one imaging unit 16A and one radar unit 16B instead of providing multiple imaging units 16A and one radar unit 16B.

[0037] <Control configuration of the reporting system> 4 is a block diagram showing the control configuration of the reporting system according to this embodiment, and only the configuration necessary in relation to the description that will be given later is shown. This system is configured to include a saddle-type vehicle 100, a mobile terminal 200, external devices 300, 400, 600, and a wearable terminal 500. Note that these configurations are merely examples and are not intended to limit the present invention. For example, the system may be configured to include only the saddle-type vehicle 100, the mobile terminal 200, and one external device, or may include more external devices.

[0038] The saddle riding type vehicle 100 includes a control unit (ECU) 101, a rollover detection sensor 102, a Bluetooth unit 103, a memory unit 104, a horn 105, a vehicle speed sensor 106, a GPS 107, and a meter panel MP. The control unit 101 includes a processor such as a CPU. The memory unit 104 stores programs executed by the processor and data used by the processor for processing. The memory unit 104 may be incorporated inside the control unit 101. The control unit 101 is connected to the other components 102 to 106 by signal lines such as a bus, can send and receive signals, and controls the entire saddle riding type vehicle 100.

[0039] The meter panel MP displays various parameters and warnings of the saddle riding type vehicle 100 to the rider. In this embodiment, at least an operation object (second operation object) for performing an operation to stop the notification is displayed on the meter panel MP. If a microphone and a speaker are built into the helmet, the operation to stop the notification may be guided by voice and may be controlled to be accepted by voice input.

[0040] The overturn detection sensor 102 incorporates a pendulum member that detects the inclination of the saddle riding type vehicle 100, and when the pendulum member is inclined at an angle of about 60 to 70 degrees, a switch is turned on and a signal is output. When these signals are input to the control unit 101, the control unit 101 determines that the saddle riding type vehicle 100 has overturned, and stops the engine. In addition, the control unit 101 notifies the mobile terminal 200 that the saddle riding type vehicle 100 has overturned via the Bluetooth unit 103. Note that it takes a certain amount of time for the overturn detection sensor 102 to detect the overturn, and during that time, there is a possibility that the short-range wireless communication with the mobile terminal 200 via the Bluetooth unit 103 will be cut off. This is because there is a possibility that the rider holding the mobile terminal 200 will be thrown out of the saddle riding type vehicle 100 when the rider overturns, and the mobile terminal 200 and the saddle riding type vehicle 100 will be separated beyond the range of the short-range wireless communication. There is no problem if the mobile terminal 200 can receive the detection result of the overturn detection sensor 102 before the short-range wireless communication is disconnected, but if the detection result cannot be received, the mobile terminal 200 cannot detect the overturn of the saddle riding type vehicle 100. Therefore, the notification according to this embodiment also includes a mechanism for periodically or irregularly transmitting information on the vehicle speed of the saddle riding type vehicle 100 to the mobile terminal 200 in advance and using that information to detect the overturn. Details will be described later.

[0041] The Bluetooth unit 103 is an example of a unit that performs short-distance wireless communication, and transmits and receives signals to and from the mobile terminal 200 via short-distance wireless communication (Bluetooth communication). The Bluetooth unit 103 is started when the saddle riding type vehicle 100 is started, and establishes a communication connection with the mobile terminal 200. The short-distance wireless communication may be a communication method that allows communication within a predetermined range, such as wireless LAN (Wi-Fi), Bluetooth, NFC, or infrared communication. The communication range is set, for example, as an area that includes a radius of 5 m to 20 m from the saddle riding type vehicle 100, and it is desirable to ensure communication with the mobile terminal 200 within the predetermined range even if the saddle riding type vehicle 100 falls over and the rider becomes separated from the saddle riding type vehicle 100.

[0042] In this embodiment, the horn 105 issues a warning by sounding it in response to an instruction from the mobile terminal 200. Note that, although an example of the warning being only a sound will be described, this is not intended to limit the present invention, and instead of or in addition to the warning by the horn 105, for example, the headlights 11 or blinkers may be turned on or off.

[0043] The vehicle speed sensor 106 detects the vehicle speed of the vehicle 100. The vehicle speed sensor 106 is supported by, for example, the front fork 95, and is a sensor that detects the amount of rotation of the front wheel FW. The vehicle speed detected by the vehicle speed sensor 106 is stored in the memory unit 104. The memory unit 104 has a ring buffer, and new vehicle speed information is overwritten over old vehicle speed information. The vehicle speed information stored in the memory unit 104 is transmitted to the mobile terminal 200 periodically or irregularly via short-range wireless communication. The vehicle speed sensor 106 may also have other speeds related to the saddle riding type vehicle 100, such as an acceleration sensor that detects acceleration in the front-rear, left-right, and up-down directions of the vehicle 100, and an angular velocity sensor that detects angular velocities in the roll, pitch, and yaw directions of the vehicle 100, and store various types of speed information in the memory unit 104. The speed, acceleration, and angular velocity of the saddle riding type vehicle 100 are collectively referred to as information related to the vehicle speed. The information about the vehicle speed is transmitted to the mobile terminal 200 periodically or irregularly via short-range wireless communication, as described above for the speeds.

[0044] The GPS 107 acquires the current position of the saddle riding type vehicle 100. Note that the GPS 107 is optional in the present invention, and if the GPS 107 is already provided in the saddle riding type vehicle 100, its position information is used to determine whether a significant difference has occurred between the information acquired by the mobile terminal 200 and the information regarding the vehicle speed, in addition to or instead of the information regarding the vehicle speed. The determination result is used to detect a rollover of the saddle riding type vehicle 100, as described above. Alternatively, if the mobile terminal 200 is not provided with a GPS function, the GPS 107 of the saddle riding type vehicle 100 may be used to acquire position information at the time of the rollover.

[0045] Next, the configuration of the mobile terminal 200 will be described. The mobile terminal 200 refers to a mobile device such as a smartphone owned by the rider of the saddle riding type vehicle 100. Here, the configuration necessary for carrying out the present invention will be mainly described. Therefore, in addition to the configuration described below, other configurations may be included. The mobile terminal 200 includes a control unit 201, a storage unit 202, an external communication device 203, a display operation unit 204, a speaker 208, and a speed sensor. The external communication device 203 includes a GPS 205, a short-range wireless device 206, and a reporting unit 207.

[0046] The control unit 201 includes a processor represented by a CPU. The storage unit 202 stores programs executed by the processor, data used by the processor for processing, and the like. The storage unit 202 may be incorporated inside the control unit 201. The control unit 201 is connected to other components 203, 204, and 208 via signal lines such as a bus, can transmit and receive signals, and controls the entire mobile terminal 200.

[0047] The control unit 201 uses the reporting unit 207 of the external communication device 203 to report to at least one of the external devices 300, 400, and 600 via a wide area network. The control unit 201 also acquires various information via the GPS 205 and the short-range wireless device 206. The GPS 205 acquires the current position of the mobile terminal 200. This makes it possible to provide position information when reporting, for example. The short-range wireless device 206 can transmit and receive signals to and from the saddle riding type vehicle 100 and the wearable terminal 500 via short-range wireless communication. The short-range wireless communication may be any communication method that allows communication within a predetermined range, such as wireless LAN (Wi-Fi), Bluetooth, NFC, or infrared communication. The communication range may be set as an area including a radius of 5 m to 20 m from the saddle riding type vehicle 100, for example. The communication connection with the saddle riding type vehicle 100 is established when the saddle riding type vehicle 100 is started.

[0048] The display operation unit 204 is, for example, a touch panel type liquid crystal display, and can perform various displays and accept user operations. An operation object (first operation object) for stopping the reporting when a fall is detected is displayed in a selectable manner on the display operation unit 204. The operation object may also be displayed on the meter panel MP of the saddle riding type vehicle 100 as described above, and stops the reporting when a fall occurs but the rider can move without any problems. Note that, instead of operating the operation object, the reporting may be stopped when the fall detection sensor 102 detects that the saddle riding type vehicle 100 has been raised from a fallen state. In addition, the period during which the operation for stopping the reporting may be dynamically changed according to the vehicle speed (travel speed) at the time of the fall. For example, if the vehicle speed is within 0 to 5 km, the rider is unlikely to be injured and the saddle riding type vehicle 100 is likely to be raised by the rider himself, so a longer period may be set as the period for performing the stop operation compared to the case of a fall during travel.

[0049] The speaker 208 outputs an alarm sound when a fall is detected. The alarm from the speaker 208 may be stopped by the rider's stop operation or by inputting an operation such as a separate stop button. When a notification stop screen described later is displayed on the display operation unit 204 in the event of a fall, it is desirable that the alarm sound be output simultaneously with the display to notify the rider of the fact, and moreover, it is desirable that the alarm sound be output at maximum volume. The volume may be configured to be able to be set in advance. In addition to the alarm sound, a message generated by voice synthesis may be played by the speaker (for example, "A fall has occurred on a motorcycle! Help please" after the alarm sound). Voice synthesis makes it possible to more clearly communicate to the surroundings what is happening.

[0050] The speed sensor 209 is an acceleration sensor that detects acceleration in the forward / backward, left / right, and up / down directions of the mobile terminal 200. An output value indicating the acceleration output from the speed sensor 209 is stored in a ring buffer of the storage unit 202, and the oldest record is overwritten. Note that the necessary data is data obtained while the saddle riding type vehicle 100 is running, and therefore it is desirable to start recording the data after the saddle riding type vehicle 100 is started and short-range wireless communication, which will be described later, is established. The recorded data is compared with the information on the vehicle speed received from the saddle riding type vehicle 100, and is used to determine whether a significant difference has occurred.

[0051] The external device 300 indicates a terminal of a report destination, which is a preset contact. The external device 300 is, for example, a mobile terminal such as a smartphone, and is a terminal owned by an acquaintance who is registered in advance by the rider. The control configuration is the same as that of the mobile terminal 200, so a detailed configuration will be omitted. The display operation unit 301 of the external device 300 displays the contents of the report by the mobile terminal 200. The details of the display contents will be described later.

[0052] The external device 400 is, for example, a terminal of an emergency contact (such as 119) that receives a report from the reporting unit 207. Here, the reporting unit 207 may output an automatic voice when the external device 400 responds to a voice call. This is because it is assumed that the rider at the time of the fall is unable to make a call for some reason. For example, the reporting unit 207 may make a call by automatic voice as a default setting, and display a switch button on the display operation unit 204 or the like for the rider to make a call from the automatic voice. When the switch button is operated, the automatic voice ends and switches to a normal voice call. The content of the automatic voice includes, for example, the occurrence of the fall accident, the place where it occurred, the time of the occurrence, and the rider's biological information.

[0053] The external device 600 is an example of a data server in this system, and is a device that accumulates various information transmitted from the mobile terminal 200. This information is used for accident investigations and the like. The communication method may be, for example, an email format, or a communication method capable of transmitting other information. The received information is stored in the data storage unit 601.

[0054] The wearable terminal 500 is a wearable terminal such as a smart watch worn by the rider, and detects the rider's biological information and transmits it to the mobile terminal 200. The wearable terminal 500 includes a biological information detection sensor 501 and a data transmission unit 502. The biological information detection sensor 501 detects biological information such as the heart rate, blood pressure, electrocardiogram, and blood oxygen of the rider wearing the wearable terminal 500. The biological information may be periodically transmitted to the mobile terminal 200 by the data transmission unit 502, or the latest data at the time of the tumble of the saddle riding type vehicle 100 may be transmitted in response to a request from the mobile terminal 200. Note that, when a request is received from the mobile terminal 200, it is desirable to detect and transmit biological information for a certain period thereafter in addition to the latest data at that time. This makes it possible to detect changes in the rider's physical condition at the time of the tumble.

[0055] <Communication connection of this system> 5 is a diagram showing the communication connection relationships of the devices in the reporting system according to this embodiment. As shown in FIG 5, the mobile terminal 200 plays a central role in this reporting system.

[0056] The mobile terminal 200 establishes short-range wireless communication (first communication) such as Bluetooth communication with the Bluetooth unit 103 of the saddle riding type vehicle 100. A connection is established for this communication when the saddle riding type vehicle 100 is started, and the communication is used for transmitting and receiving information regarding the vehicle speed while traveling, and when a fall is detected by the fall detection sensor 102, information indicating that a fall has occurred and various other information. The mobile terminal 200 also establishes short-range wireless communication (third communication) such as Bluetooth communication with the wearable terminal 500. A connection is established for this communication when the wearable terminal 500 is started, and biological information of the rider and the like are transmitted and received.

[0057] Furthermore, the mobile terminal 200 can communicate with each of the external devices 300, 400, and 600 via broadband wireless communication (second communication). The mobile terminal 200, for example, makes an emergency call to the external device 400, and notifies the external device 300 and the external device 600 of various information such as location information, biological information, and vehicle speed by email or the like.

[0058] <Mobile device processing procedure> 6 is a flowchart showing the basic flow of processing steps when the mobile terminal 200 according to this embodiment falls over. The processing described below is realized, for example, by the CPU of the control unit 201 reading a program stored in the ROM or storage unit 202 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process.

[0059] First, in S601, the control unit 201 of the mobile terminal 200 establishes a communication connection with the Bluetooth unit 103 of the saddle riding vehicle 100 via the short-range wireless device 206 when the saddle riding vehicle 100 is started. Next, in S602, the control unit 201 judges whether or not information has been received from the saddle riding vehicle 100 via the short-range wireless communication connection established in S601. If no information has been received, the judgment in S602 is repeated. If information has been received, the process proceeds to S603, where the control unit 201 judges whether or not the received information is information related to a rollover of the saddle riding vehicle 100. Here, the information related to a rollover refers to information received when a rollover is detected by the rollover detection sensor 102 of the saddle riding vehicle 100. If the information is related to a rollover, the process proceeds to S604, where the control unit 201 executes a process during a rollover and ends the process. Details of the process during a rollover will be described later with reference to FIG. 8A. On the other hand, if the information is not related to a rollover, the process proceeds to S605, where the control unit 201 executes a process for determining whether or not the information is related to a rollover. Details of the fall determination process will be described later with reference to Fig. 8B. Next, in S606, the control unit 201 determines whether or not a fall has been detected as a result of the fall determination process in S605. If a fall has been detected, the process proceeds to S604, and if not, the process proceeds to S607, where the control unit 201 executes other processes according to the received information and ends the process.

[0060] <Procedure for handling when a saddle-type vehicle falls over> 7 is a flowchart showing the processing procedure when the saddle riding type vehicle 100 according to this embodiment rolls over. The processing described below is realized, for example, by the CPU of the control unit 101 reading a program stored in the ROM or the storage unit 104 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process.

[0061] First, in S701, when the saddle riding type vehicle 100 is started, the control unit 101 of the saddle riding type vehicle 100 establishes a short-range wireless communication connection with the mobile terminal 200 via the Bluetooth unit 103. Next, in S702, the control unit 101 stores information about the vehicle speed acquired by the vehicle speed sensor 106, such as at least one of the travel speed, acceleration, and angular velocity, in the storage unit 104 and transmits the information to the mobile terminal 200 via short-range wireless communication. The transmission may be periodic or irregular.

[0062] Next, in S703, the control unit 101 determines whether or not there is a signal input from the overturn detection sensor 102. If there is no signal input, the process returns to S702. On the other hand, if there is a signal input from the overturn detection sensor 102, the process proceeds to S704, where the control unit 101 determines that a overturn of the saddle riding type vehicle 100 has been detected, transmits a notice that a overturn has occurred and various information to the mobile terminal 200 via the short-range wireless communication connection established in S701, and ends the process. The various information transmitted here is operation information when the saddle riding type vehicle 100 overturns, such as vehicle speed information and position information before the overturn that are stored in the storage unit 104. Of course, other operation information may be transmitted. For example, information detectable by a group of sensors provided in the saddle riding type vehicle 100, such as a faulty part and various other information, may be transmitted.

[0063] <Details on how to handle a mobile device when it falls over> 8A is a flowchart showing the detailed procedure of the above-mentioned S604 process at the time of falling in the mobile terminal 200 according to this embodiment. The process described below is realized, for example, by the CPU of the control unit 201 reading a program stored in the ROM or the storage unit 202 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process.

[0064] When it is determined in S603 that a fall has been detected, in S801, the control unit 201 instructs the saddle riding type vehicle 100 via the short-range wireless device 206 to output an alarm sound from the speaker 208 and sound the horn 105. In addition, in S802, the control unit 201 acquires information on a contact to be made in advance in the event of a fall from the storage unit 202. In addition, in S803, the control unit 201 instructs the display operation unit 204 to display a notification stop screen 1100 including a first operation object described later, and instructs the saddle riding type vehicle 100 via the short-range wireless device 206 to display a second operation object for stopping a notification on the meter panel MP. Details of the notification stop screen 1100 will be described later with reference to FIG. 11. The order of the processes from S801 to S803 is not particularly limited and may be any order. In addition, the alarm instruction and display instruction in S801 and S803, which are instructions given to the saddle riding type vehicle 100, may be given collectively.

[0065] Next, in S804, the control unit 201 judges whether or not a report stop operation has been received by operating the first operation object or the second operation object. If a stop operation has been received, the process proceeds to S805, and if not, the process proceeds to S808. For example, if a stop operation is not received within a predetermined time (e.g., 30 seconds) from the start of displaying the report stop screen 1100, the control unit 201 judges that the stop operation has not been received and proceeds to report processing. Also, as described above, the predetermined time may be changed according to the vehicle speed immediately before the fall. Note that, although the operation of the operation object for issuing a report stop instruction has been described here, the present invention is not limited to this, and the process of S808 may be executed assuming that a stop operation has been received even when, for example, the rider has repositioned the fallen saddle riding type vehicle 100. The fact that the saddle riding type vehicle 100 has been repositioned may be determined as a trigger, for example, by the stop of the signal input from the fall detection sensor 102. Also, the stop operation may be performed by, for example, pressing and holding a button provided on the saddle riding type vehicle 100. In S808, the control unit 201 instructs the saddle riding type vehicle 100 via the short-range wireless device 206 to stop outputting the alarm sound that has been being output, and to stop sounding the horn 105, and then ends the process.

[0066] On the other hand, in S805, the control unit 201 acquires the rider's biological information from the wearable terminal 500. Note that in this reporting system, the wearable terminal 500 is an optional and not a required component. In other words, if the rider is not wearing the wearable terminal 500, the process of S805 is skipped. Next, in S806, the control unit 201 acquires current position information via the GPS 205. After that, in S807, the control unit 201 reports the occurrence of a fall, and biological information, position information, vehicle speed information, and the like to a pre-set contact, as necessary, and ends the process. Note that, if multiple contacts are set, reports are made in sequence. These reports are made in priority order, for example, to the external device 400, which is an emergency contact, the external device 300, and the external device 600.

[0067] <Details of mobile device fall detection process> 8B is a flowchart showing the detailed procedure of the fall determination process of S605 in the mobile terminal 200 according to this embodiment. The process described below is realized, for example, by the CPU of the control unit 201 reading a program stored in the ROM or storage unit 202 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process.

[0068] If it is determined in S603 that a fall has not been detected, then in S811 the control unit 201 receives information about the vehicle speed from the saddle riding vehicle 100 via the short-range wireless device 206. Here, for example, this is information about the moving speed and acceleration measured by the saddle riding vehicle 100. Next, in S812, the control unit 201 determines whether the vehicle speed (for example, the moving speed) is equal to or greater than a predetermined value. The predetermined value here can be set to any speed value, but may be set to, for example, 10 km per hour so as to detect a fall that occurs while traveling. If it is equal to or greater than the predetermined value, the process proceeds to S813, and if it is not equal to or greater than the predetermined value, the process proceeds to S815. In S815, the control unit 201 determines that a fall has not been detected and ends the process.

[0069] In S813, the control unit 201 acquires from the storage unit 202 the latest acceleration of the mobile terminal 200 measured by the speed sensor 209 of the mobile terminal 200, and judges whether or not there is a significant difference between the acceleration acquired from the storage unit 202 and the acceleration received from the saddle riding type vehicle 100 in S811. More specifically, the control unit 201 compares the two accelerations, and judges that there is a significant difference if the difference is equal to or greater than a predetermined threshold. Here, the predetermined threshold is set to, for example, a speed of 5 km to 10 km per hour. If there is a difference equal to or greater than the threshold, it is judged that the saddle riding type vehicle 100 has fallen, the rider has fallen off, and a difference in the accelerations of the saddle riding type vehicle 100 and the mobile terminal 200 held by the rider has occurred. In other words, according to this embodiment, even if the detection result of the fall detection sensor 102 has not been received, and even if the vehicle speed (travel speed) is equal to or greater than a certain level, if there is a significant difference between the accelerations detected by the saddle riding type vehicle 100 and the mobile terminal 200 held by the rider, it is judged that there has been a fall.

[0070] If it is determined that a significant difference has occurred in the acceleration, the process proceeds to S814, where the control unit 201 determines that a fall has occurred and ends the process. On the other hand, if it is determined that no significant difference has occurred in the acceleration, the process proceeds to S815, where the control unit 201 determines that a fall has not occurred and ends the process. A fall may also be determined to have occurred when a sudden change in acceleration has occurred (assuming that the saddle-type vehicle has collided with another vehicle or an obstacle). In this case, the degree of injury may be further predicted from the acceleration immediately before the fall. Even if a primary determination has been made that a fall has occurred due to this sudden change in acceleration, if the vehicle speed is subsequently detected to be continuous for a certain period of time or more, it may be determined that the vehicle is continuing to travel and the primary determination of a fall may be withdrawn.

[0071] <Processing procedure when receiving an alarm instruction for a saddle-type vehicle> 9 is a flowchart showing the processing procedure when an alarm instruction is received in the saddle riding type vehicle 100 according to this embodiment. The processing described below is realized, for example, by the CPU of the control unit 101 reading a program stored in the ROM or the storage unit 104 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process.

[0072] First, in S901, the control unit 101 receives an instruction to issue an alarm from the mobile terminal 200 via the Bluetooth unit 103, and in S902, the control unit 101 causes the horn 105 to sound. Here, the control unit 101 may cause the horn 105 to sound after a predetermined time has elapsed since the first operation object is displayed on the mobile terminal 200. In this way, for example, when a stop operation is accepted via the first operation object, the sounding of the horn 105 is an unnecessary alarm, and such an alarm can be avoided. In addition, in S903, the control unit 101 receives a display instruction for a stop screen for stopping a report from the mobile terminal 200 via the Bluetooth unit 103, and in S904, displays a report stop screen including a second operation object on the meter panel MP. As described above, the alarm instruction and the display instruction in S901 and S903 may be received together.

[0073] Next, in S905, the control unit 101 determines whether a stop operation has been accepted via the meter panel MP, or whether a stop instruction has been received from the mobile terminal 200. If accepted, the process proceeds to S906, and if not, the determination of S905 is repeated. In S906, the control unit 101 stops sounding the horn 105, and ends the process.

[0074] <Settings screen> 10 shows an example of a contact setting screen 1000 displayed on the mobile terminal 200 according to the present embodiment. The setting screen 1000 is displayed on the display operation unit 204. Note that the setting screen 1000 described below may be displayed on the meter panel MP so as to be operable based on an instruction from the mobile terminal 200.

[0075] As shown in Fig. 10, the setting screen 1000 includes setting fields for emergency contact 1001, user-defined telephone communication contact setting 1002, and user-defined email destination setting 1004. Each setting field can be set by inputting the corresponding contact. In addition, "119" is preset as a default setting for the emergency contact 1001. The setting screen 1000 further includes add buttons 1003 and 1005 corresponding to the contact setting 1002 and destination setting 1004, respectively. When each of the add buttons 1003 and 1005 is selected, the setting fields for the contact and destination can be increased.

[0076] Furthermore, the setting screen 1000 includes an OK button 1006 and a cancel button 1007. When the OK button 1006 is selected, the contacts, etc., set on the setting screen 1000 are finalized and saved in the storage unit 202. On the other hand, when the cancel button 1007 is selected, the contacts, etc., set on the setting screen 1000 are cancelled and the setting information is not changed.

[0077] <Notification stop screen> 11 shows an example of a notification stop screen 1100 displayed on the mobile terminal 200 according to this embodiment. The notification stop screen 1100 is displayed on the display operation unit 204. Note that a screen equivalent to the notification stop screen 1100 described below is displayed on the meter panel MP in an operable manner based on an instruction from the mobile terminal 200, but a detailed description thereof will be omitted.

[0078] As shown in FIG. 11, the report stop screen 1100 includes a display indicating that a report will be sent to a contact 1101 and a destination 1102 after a predetermined time (30 seconds in this example) has elapsed since a fall of the motorcycle, which is the saddle riding type vehicle 100, has been detected, and a display prompting the user to select a stop button to stop the report if there is no problem. Furthermore, the report stop screen 1100 includes a stop button 1103 and a report button 1104. When the stop button 1103 is selected, the mobile terminal 200 determines that a report stop operation has been received, stops the alarm processing and the report processing, and notifies the saddle riding type vehicle 100 that the stop operation has been received. Furthermore, when the report button 1104 is selected, the mobile terminal 200 starts the report processing without waiting for the predetermined time to elapse. The stop button 1103 is an example of a first operation object. Furthermore, the second operation object displayed on the meter panel MP of the saddle riding type vehicle 100 is equivalent to the stop button 1103. Furthermore, the meter panel MP may display a button corresponding to the report button 1104. It is also preferable that the stop button 1103 continues to be displayed even after the above-mentioned predetermined time has elapsed. This is because the alarm can be stopped by operating the stop button when a rescuer arrives.

[0079] <Report screen> 12 shows an example of a notification screen 1200 displayed on the external device 300 according to this embodiment. The notification screen 1200 is displayed on the display operation unit 301. Note that the notification screen 1200 described below may be displayed on another external device.

[0080] The report screen 1200 is a screen displayed on the external device 300 after being notified to an address set in the destination setting 1004, which is set in advance in the user settings of the setting screen 1000. Various notification methods can be applied as a method of notifying the external device 300. For example, the screen information of the report screen 1200 may be transmitted to the external device 300, or only various information such as location information and biological information may be transmitted together with the fact that the user has fallen. In addition, if an application related to the present reporting system is installed in the external device 300, the report screen 1200 may be displayed on the application using the information, or may be displayed on an arbitrary browser screen. In addition, only the message or information may be received by email and displayed on a mailer application. Alternatively, the message or information may be displayed on an SNS application.

[0081] The notification screen 1200 includes a message 1201 notifying the rider of the saddle riding type vehicle 100 that the rider has fallen, a map 1202 indicating the position of the fall, biological information 1203 of the rider, and a voice transmission button 1204 to the rider. These components can be selected according to the application to be displayed.

[0082] The map 1202 displays a mark 1205 on the map indicating the position of the fall, the vehicle speed 1206 immediately before the fall, and detailed information 1207 on the position of the fall. The biological information 1203 displays, for example, an electrocardiogram, heart rate, blood pressure, and blood oxygen. When the voice transmission button 1204 is selected, the external device 300 transmits voice to the mobile terminal 200.

[0083] <Second embodiment> The second embodiment of the present invention will be described below. As described with reference to FIG. 8B in the first embodiment, even if the detection result of the fall detection sensor 102 has not been received, if a significant difference occurs between the accelerations acquired by the saddle riding type vehicle 100 and the mobile terminal 200 at a certain speed or higher, it is determined that a fall has occurred. However, in this embodiment, if a significant difference occurs in the accelerations, the range of short-distance wireless communication between the saddle riding type vehicle 100 and the mobile terminal 200 is expanded to receive information from the saddle riding type vehicle 100 again, and if the detection result of the fall detection sensor 102 has not been received, it is further determined whether a significant difference occurs between the two accelerations. After that, if the mobile terminal 200 does not receive the detection result of the fall detection sensor 102 even in the maximum communication range specified in advance and a significant difference occurs between the two accelerations, it is determined that a fall has occurred. In other words, according to this embodiment, even if a significant difference occurs between the two accelerations, a fall is not immediately determined, but the communication range of short-distance wireless communication is expanded to the maximum communication range, providing a grace period for receiving the detection result of the fall detection sensor 102. This is because judging a fall based on the detection result of the fall detection sensor 102 is more accurate than judging from a significant difference in acceleration. Note that the same reference numerals and steps are used for the same configurations and controls as those in the first embodiment, and the description thereof will be omitted.

[0084] <Details of mobile device fall detection process> Fig. 13 is a flowchart showing the detailed procedure of the fall determination process of S605 in the mobile terminal 200 according to this embodiment. The process described below is realized, for example, by the CPU of the control unit 201 reading a program stored in the ROM or storage unit 202 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process. Also, the same step numbers are used for processes similar to those in Fig. 8B, and descriptions thereof will be omitted.

[0085] If it is determined in S813 that a significant difference has occurred in the acceleration, then in S1301 the control unit 201 determines whether the communication range of the short-range wireless communication between the short-range wireless device 206 and the saddle riding vehicle 100 is maximum. If it is not maximum, the process proceeds to S1302, where the control unit 201 increases the antenna output of the short-range wireless device 206 and returns the process to S602 in Fig. 6, where the control unit 201 again receives information about the vehicle speed from the saddle riding vehicle 100. Alternatively, the antenna output may be increased to the maximum output all at once, or may be increased in stages.

[0086] On the other hand, if it is determined in S1301 that the communication range is maximum, the process proceeds to S814, where the control unit 201 determines that a fall has occurred, and ends the process. Also, once it is determined in S813 that a significant difference has occurred and the process returns to S602, it may be assumed that information from the saddle riding type vehicle 100 will subsequently be interrupted. In such a case, a fall may be determined to have occurred a predetermined time after it was first determined that a significant difference has occurred in acceleration.

[0087] <Modification> In the first and second embodiments, whether or not a significant difference occurs in the accelerations acquired by the saddle riding vehicle 100 and the mobile terminal 200 is used as a criterion for determining whether or not a rollover has occurred. The present invention is not limited to this, and other determination methods may be used. For example, a rollover of the saddle riding vehicle 100 may be detected based on whether or not a significant difference occurs between the position information acquired by the GPS 107 of the saddle riding vehicle 100 and the position information acquired by the GPS 205 of the mobile terminal 200. Alternatively, a rollover of the saddle riding vehicle 100 may be detected when a significant difference occurs in both the acceleration and the position information. A significant difference in the position information may be, for example, 5 m to 10 m.

[0088] <Summary of the embodiment> The above-described embodiment discloses at least the following program, saddle-type vehicle, and system.

[0089] 1. A program (202) for causing a computer to execute each step of a control method for a mobile terminal (200) including a first communication means (206) for performing short-range wireless communication with a saddle-type vehicle (100), a second communication means (207) for communicating with an external device, and an acceleration sensor (209), the control method comprising: a receiving step (S602) of receiving information from the saddle riding type vehicle via the first communication means; a comparison step (S813) of comparing an acceleration of the saddle riding type vehicle included in the information from the saddle riding type vehicle with an acceleration acquired by an acceleration sensor of the mobile terminal to determine whether or not there is a significant difference when the moving speed of the saddle riding type vehicle included in the information from the saddle riding type vehicle is equal to or greater than a predetermined value; a rollover determination step (S814) of determining that the saddle riding type vehicle has rolled over based on a determination that a significant difference has occurred in the comparison step; Includes. According to this embodiment, the information relating to the vehicle speed received from the saddle riding type vehicle 100 and the information relating to the acceleration acquired by the mobile terminal 200 are compared to detect a rollover of the saddle riding type vehicle 100 in the mobile terminal 200. In addition, since the rollover can be determined by the mobile terminal 200, a report can also be made by utilizing the communication function of the mobile terminal 200, such as a smartphone.

[0090] 2. In the above embodiment, The saddle riding type vehicle (100) is provided with a rollover detection means (102) for detecting a rollover of the saddle riding type vehicle, and a Bluetooth unit (103), In the overturn determination step, if the information from the saddle riding type vehicle includes the output of the overturn detection means, it is determined that the saddle riding type vehicle has overturned regardless of the determination result in the comparison step (S603).

[0091] According to this embodiment, a fall can be determined based on the output of the fall detection sensor 102 provided in the saddle riding type vehicle 100, so that a fall can be determined with higher accuracy. Also, the saddle riding type vehicle 100 is only provided with a Bluetooth unit 103, and the 4G / 5G communication itself can utilize a mobile terminal 200 such as a smartphone of the rider. Therefore, even when making a report, it is possible to unify the communication into the smartphone from the viewpoint of communication costs.

[0092] 3. In the above embodiment, In the falling determination step, in response to a determination that a significant difference has occurred in the comparison step, If the communication range of the first communication means with the saddle riding type vehicle is not the maximum communication range, the antenna output of the first communication means is increased (S1301, S1302); When the communication range with the saddle riding type vehicle by the first communication means is the maximum communication range, it is determined that the saddle riding type vehicle has fallen over (S1301, S814).

[0093] According to this embodiment, even if the saddle-type vehicle 100 and the mobile terminal 200 carried by the rider are physically separated when the saddle-type vehicle 100 falls over, a certain degree of communication can be ensured and the output of the fall detection sensor 102 can be received.

[0094] 4. In the above embodiment, The mobile terminal further comprises a location information acquisition means (205) for acquiring location information of the mobile terminal, In the comparison step, instead of or in addition to the significant difference regarding the acceleration, The position information (107) of the saddle riding type vehicle included in the information from the saddle riding type vehicle is compared with the position information acquired by the position information acquisition means of the mobile terminal to determine whether or not there is a significant difference (S813).
