The left and right of the saddle riding 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 vehicle may be simply referred to as the front or rear. Additionally, the inside or outside of the vehicle width direction (left-to-right direction) of the saddle riding vehicle may be simply referred to as the inside or outside.

<Overall configuration of the reporting system>
An 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 is configured to include 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 be included.

This system detects a fall of the saddle-type vehicle 100, and the mobile terminal 200 carried by the rider of the saddle-type vehicle 100 collects various information and sends a report via broadband wireless communication such as mobile communication (4G, 5G) to predetermined contacts, such as emergency contacts (119), a mobile terminal of an acquaintance, or an external device such as an information storage server. These predetermined contacts can be set in advance. The external device 300 refers to the mobile terminal of an acquaintance set as the predetermined contact, and the external device 400 refers to, for example, a fire station terminal connected by calling 119, or a terminal of a hospital, etc.

The mobile terminal 200 receives the detection result of the fall detection sensor 102 provided on the saddle riding vehicle 100 by short-range wireless communication (here, Bluetooth communication) via the Bluetooth (registered trademark) unit 103, and determines whether the saddle riding vehicle 100 has fallen. If it determines that the saddle riding vehicle 100 has fallen, 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 specified contact of the fact that the vehicle 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, and transmits the detected biological information to the mobile terminal 200 by short-range wireless communication (e.g., Bluetooth communication).

In this way, in this system, the mobile terminal 200 collects various information in the event of a fall and reports the information via broadband wireless communication. This eliminates the need to provide a separate unit for broadband wireless communication in the saddle-type vehicle 100, and allows for convenient reporting. Furthermore, according to this embodiment, even if the rider is thrown away from the saddle-type vehicle 100 in the event of a fall and becomes separated from it, the rider can operate the mobile terminal 200 in his/her hand to perform various operations, such as stopping reporting, which will be described later.

<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.

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. Also, 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.

The vehicle 100 is equipped with a power unit 2 between the front wheels FW and the rear wheels RW.

The rear swing arm is able to swing up and down, and the rear wheel RW is supported at its rear end. An exhaust muffler 6 that silences the exhaust of the engine 21 is provided extending in the X direction on the sides of the lower part of the rear wheel RW. Left and right saddlebags 7a are provided on the sides of the upper part of the rear wheel RW.

A front suspension mechanism 9 that supports the front wheel FW is configured 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.

The upper link 91 and the lower link 92 are arranged at a distance above and below the front end of the main frame 31. The rear ends of the upper link 91 and the lower link 92 are swingably connected to supports 31a and 31b provided at the front end of the main frame 31. The front ends of the upper link 91 and the lower link 92 are swingably 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 arranged substantially parallel to each other.

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 freely swingable by the main frame 31. The lower end of the cushion unit 94 is supported so as to be freely swingable by the lower link 92.

The fork support 93 is cylindrical and tilted backward. The front end of the upper link 91 is rotatably connected to the upper front part of the fork support 93. The front end of the lower link 92 is rotatably connected to the lower rear part of the fork support 93.

A steering shaft 96 is supported on the fork support 93 so as to be rotatable about its axis. The steering shaft 96 has an axle portion (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 on 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.

The vehicle 100 is equipped with a brake device 19F that brakes the front wheels FW and a brake device 19R that brakes the rear wheels RW. The brake 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 brake devices 19F and 19R are, for example, disc brakes. When there is no need to distinguish between the brake devices 19F and 19R, they are collectively referred to as brake devices 19.

A headlight 11 that irradiates light ahead of the vehicle 100 is disposed at the front of the vehicle 100. In this embodiment, the headlight 11 is a two-lens type headlight unit that has a right light irradiation section 11R and a left light irradiation section 11L arranged symmetrically. However, a one-lens type or three-lens type headlight unit, or an asymmetric two-lens type headlight unit can also be used.

The front of the vehicle 100 is covered by a front cowl 12, and the front sides of the vehicle 100 are covered by 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 traveling, and is formed, for example, from a transparent resin material.

A pair of left and right side mirror units 15 are arranged on the sides of the front cowl 12. The side mirror units 15 support side mirrors (not shown) that allow the rider to see behind the vehicle.

In this embodiment, the front cowl 12 is made up of cowl members 121 to 123. Cowl member 121 extends in the Y direction and forms the main body of the front cowl 12, while cowl member 122 forms the upper portion of cowl member 121. Cowl member 123 is disposed spaced downward from cowl member 121.

An opening exposing the headlight 11 is formed between the cowl members 121 and 123 and between the pair of left and right side cowls 14, with the upper edge of this opening being defined by the cowl members 121, the lower edge being defined by the cowl members 123, and the left and right side edges being defined by the side cowls 14.

An imaging unit 16A and a radar unit 16B are disposed behind the front cowl 12 as detection devices that detect 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 of the area 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. An opening 122a is formed through the cowl member 122, and the imaging unit 16A captures an image of the area ahead of the vehicle 100 through the opening 122a.

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 appearance of the vehicle 100 from being deteriorated. The cowl member 121 is made of a material that allows electromagnetic waves to pass through, such as resin.

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 in front 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 multiple imaging units 16A and multiple radar units 16B.

<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.

The saddle-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, 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-type vehicle 100.

The meter panel MP displays various parameters and warnings of the saddle riding 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. In addition, if the helmet has a built-in microphone and speaker, the operation to stop the notification may be guided by voice and controlled to be accepted by voice input.

The overturn detection sensor 102 incorporates a pendulum member that detects the inclination of the saddle riding vehicle 100, and when the pendulum member is tilted 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 vehicle 100 has overturned and stops the engine. The control unit 101 also notifies the mobile terminal 200 via the Bluetooth unit 103 that the saddle riding vehicle 100 has overturned.

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

In this embodiment, the horn 105 sounds an alarm in response to an instruction from the mobile terminal 200. Note that, although an example of an alarm in which only sound is sounded will be described, this is not intended to limit the present invention, and instead of or in addition to an alarm from the horn 105, for example, the headlights 11 or turn signals may be turned on or flashed.

The vehicle speed sensor 106 detects the vehicle speed of the vehicle 100. The vehicle speed sensor 106 is supported, for example, by 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 may be transmitted to the mobile terminal 200 when a fall is detected. The vehicle speed sensor 106 may also have other speeds related to the saddle-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 may store various types of speed information in the memory unit 104.

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-type vehicle 100. Here, the configuration necessary for implementing the present invention will be mainly described. Therefore, in addition to the configuration described below, other configurations may also be included. The mobile terminal 200 includes a control unit 201, a memory unit 202, an external communication device 203, a display operation unit 204, and a speaker 208. The external communication device 203 includes a GPS 205, a short-range wireless device 206, and a reporting unit 207.

The control unit 201 includes a processor such as a CPU. The memory unit 202 stores programs executed by the processor and data used by the processor for processing. The memory 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 send and receive signals, and controls the entire mobile terminal 200.

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 send and receive signals to and from the saddle-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, for example, as an area including a radius of 5 to 20 m from the saddle-type vehicle 100. The communication connection with the saddle-type vehicle 100 is established when the saddle-type vehicle 100 is started.

The display operation unit 204 is, for example, a touch panel type liquid crystal display, and can display various information and accept user operations. The display operation unit 204 displays an operation object (first operation object) for stopping the reporting when a fall is detected, in a selectable manner. The operation object may also be displayed on the meter panel MP of the saddle riding vehicle 100 as described above, and stops the reporting when a fall occurs but the rider can move without any problems. The reporting may be stopped when the fall detection sensor 102 detects that the saddle riding vehicle 100 has been raised from a fallen state, instead of operating the operation object. The period during which the reporting stop operation is allowed may be dynamically changed according to the vehicle 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 vehicle 100 is likely to be raised by the rider himself, so a longer period may be set as the period for the stop operation compared to when the vehicle falls while traveling.

The speaker 208 outputs an alarm sound when a fall is detected. The alarm from the speaker 208 may be stopped by the rider performing the above-mentioned stop operation, or by inputting an operation such as a separate stop button. When a notification stop screen described below is displayed on the display operation unit 204 in the event of a fall, it is desirable for the alarm sound to be output simultaneously with the display to notify the rider of the occurrence, and it is also desirable for the alarm sound to 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, after the alarm sound, "There has been a fall on my motorcycle! Help please."). Voice synthesis makes it possible to more clearly communicate to those around you what is happening.

The external device 300 indicates the terminal to which the report is to be sent, 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 has been registered in advance by the rider. The control configuration is similar to that of the mobile terminal 200, so a detailed description of the configuration is omitted. The display operation unit 301 of the external device 300 displays the contents of the report sent by the mobile terminal 200. Details of the display contents will be described later.

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 answers 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 using an automatic voice as a default setting, and display a switch button on the display operation unit 204 or the like that allows 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 location of the occurrence, the time of the occurrence, and the rider's biological information.

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, etc. The communication method may be, for example, email format, or a communication method capable of transmitting other information. The received information is stored in the data storage unit 601.

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. This 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 saddle-type vehicle 100 falling over may be transmitted in response to a request from the mobile terminal 200. Note that, when a request is made from the mobile terminal 200, it is desirable to detect and transmit biological information for a certain period of time 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 fall.

<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.

The mobile terminal 200 establishes short-range wireless communication (first communication) such as Bluetooth communication with the Bluetooth unit 103 of the saddle riding vehicle 100. This communication is established when the saddle riding vehicle 100 is started up, and is used to send and receive information about a fall detected by the fall detection sensor 102, as well as various other information. The mobile terminal 200 also establishes short-range wireless communication (third communication) such as Bluetooth communication with the wearable terminal 500. This communication is established when the wearable terminal 500 is started up, and is used to send and receive information such as the rider's biological information.

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, biometric information, and vehicle speed by e-mail or the like.

<Processing procedure of mobile terminal>
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.

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 determines 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 determination in S602 is repeated. If information has been received, the process proceeds to S603, where the control unit 201 determines whether or not the received information is information regarding a rollover of the saddle riding vehicle 100. If the received information is information regarding 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. 8. On the other hand, if the received information is not information regarding a rollover, the process proceeds to S605, where the control unit 201 executes other processes according to the received information and ends the process.

<Procedure for handling when a saddle-type vehicle rolls over>
7 is a flowchart showing a processing procedure when the saddle riding type vehicle 100 according to this embodiment falls 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 storage unit 104 into the RAM and executing it. Note that the numbers following S indicate the step numbers of each process.

First, in S701, the control unit 101 of the saddle riding vehicle 100 establishes a short-range wireless communication connection with the mobile terminal 200 via the Bluetooth unit 103 when the saddle riding vehicle 100 is started. Next, in S702, the control unit 101 determines whether there is a signal input from the fall detection sensor 102. If there is no signal input, the determination in S702 is repeated periodically. On the other hand, if there is a signal input from the fall detection sensor 102, the process proceeds to S703, and the control unit 101 determines that the saddle riding vehicle 100 has been detected as having fallen, transmits 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 at the time of the saddle riding vehicle 100 falling, such as vehicle speed information before the fall stored in the memory unit 104. Of course, other operation information may be transmitted. For example, location information, faulty part information, and various other information that can be detected by a group of sensors provided on the saddle riding vehicle 100 may be transmitted.

<Details of how the mobile device handles falls>
8 is a flowchart showing the detailed procedure of the above-mentioned fall-over process in S604 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.

When it is determined in S603 that a fall has been detected, in S801, the control unit 201 outputs an alarm sound from the speaker 208 and instructs the saddle riding type vehicle 100 via the short-range wireless device 206 to 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 the notification on the meter panel MP. Details of the notification stop screen 1100 will be described later using 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 together.

Next, in S804, the control unit 201 determines whether or not a notification 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. 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 notification stop screen 1100, the control unit 201 determines that the stop operation has not been received and proceeds to notification processing. In addition, the predetermined time may be changed according to the vehicle speed immediately before the fall, as described above. Note that, although the operation of the operation object for issuing a notification stop instruction is 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 the rider recovers the fallen saddle-type vehicle 100. The recovery of the saddle-type vehicle 100 may be determined as a trigger, for example, by the stop of the signal input from the fall detection sensor 102. In addition, the stop operation may be performed by pressing and holding a button provided on the saddle-type vehicle 100. In S808, the control unit 201 instructs the saddle-type vehicle 100 via the short-range wireless device 206 to stop outputting the alarm sound and to stop sounding the horn 105, and then ends the process.

Meanwhile, in S805, the control unit 201 acquires the rider's biometric 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 notifies the previously set contacts that a fall has occurred, and, as necessary, biometric information, position information, vehicle speed information, etc., 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.

<Processing procedure when a warning instruction is received from a saddle-type vehicle>
9 is a flowchart showing a 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 storage unit 104 into the RAM and executing the program. Note that the numbers following S indicate the step numbers of each process.

First, in S901, the control unit 101 receives an alarm instruction from the mobile terminal 200 via the Bluetooth unit 103, and in S902, the control unit 101 sounds the horn 105. Here, the control unit 101 may sound the horn 105 after a predetermined time has elapsed since the first operation object was 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 the report from the mobile terminal 200 via the Bluetooth unit 103, and in S904, displays a report stop screen including the second operation object on the meter panel MP. As described above, the alarm instruction and display instruction in S901 and S903 may be received together.

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 in S905 is repeated. In S906, the control unit 101 stops sounding the horn 105, and ends the process.

<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.

As shown in FIG. 10, the setting screen 1000 includes setting fields for emergency contact 1001, user-defined telephone 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 the default setting for emergency contact 1001. The setting screen 1000 further includes add buttons 1003 and 1005 corresponding to contact setting 1002 and destination setting 1004, respectively. When each of the add buttons 1003 and 1005 is selected, the number of setting fields for the contact and destination can be increased.

The setting screen 1000 also includes an OK button 1006 and a cancel button 1007. When the OK button 1006 is selected, the contacts and other information set on the setting screen 1000 are finalized and stored in the storage unit 202. On the other hand, when the cancel button 1007 is selected, the contacts and other information set on the setting screen 1000 are cancelled and the setting information is not changed.

<Report 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.

11, the report stop screen 1100 includes a display indicating that a report will be sent to the contact 1101 and the destination 1102 after a predetermined time (30 seconds in this case) 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 the 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 the report stop operation has been accepted, stops the alarm processing and the report processing, and notifies the saddle riding type vehicle 100 that the stop operation has been accepted. Also, 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. Also, 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, a button corresponding to the report button 1104 may be displayed on the meter panel MP. It is also preferable that the stop button 1103 continue to be displayed even after the above-mentioned predetermined time has elapsed. This is so that the alarm can be stopped by operating it when rescuers arrive.

<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.

The notification 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 notification screen 1200 may be sent to the external device 300, or only various information such as location information and biometric information may be sent along with the fact that the user has fallen. In addition, if an application related to this notification system is installed in the external device 300, the notification 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, it may be displayed on an SNS application.

The notification screen 1200 includes a message 1201 informing the user that the rider of the saddle riding vehicle 100 has fallen, a map 1202 showing the location of the fall, the rider's biometric information 1203, and a button 1204 to send a voice message to the rider. These components can be selected according to the application to be displayed.

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