Description

The present invention relates to a program, information processing method, and system that detects and reports the tipping over of a saddle-type vehicle.

In saddle-type vehicles, technology is known that detects a rollover of the vehicle body and automatically reports it. Patent Document 1 proposes technology related to a cancel switch that can cancel a report when a rollover occurs but a report is not necessary.

International Publication No. 2018/225427

In the above conventional technology, when the body of the vehicle falls, it is detected by sensors on the motorcycle and a report is made via the communication unit. However, if a communication unit is incorporated into the motorcycle, the motorcycle itself needs to be equipped with a communication function that can send reports, 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 when the motorcycle has fallen in the external device that sends the report.

The object of the present invention is to detect the toppling of a saddle-type vehicle using a mobile terminal. It is also to reduce communication costs by reporting the toppling using the communication unit of the mobile terminal.

According to the present invention,
A second portable terminal capable of wireless communication with the saddle riding type vehicle and the first portable terminal,
a receiving step of receiving information indicating a moving speed of the saddle riding type vehicle from the saddle riding type vehicle;
an acquisition step of acquiring information indicating a first communication state, which is a communication state between the saddle riding type vehicle and the first portable terminal , from the first portable terminal or the saddle riding type vehicle ;
a rollover determination step of determining that the saddle riding type vehicle has rolled over when the moving speed of the saddle riding type vehicle based on the information received in the receiving step is equal to or higher than a predetermined speed and the first communication state is interrupted;
A program that executes the following.
is provided.

According to the present invention, the mobile terminal can determine a fall and automatically send a report to a pre-set contact. In addition, there is no need to provide a wideband wireless communication unit for sending a report to the saddle-type vehicle, and the rider's smartphone or the like can be used, reducing communication costs.

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.

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 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.

In this system, the saddle-type vehicle 100, the mobile terminal 200, and the wearable terminal 500 communicate with each other by wireless communication (here, Bluetooth communication) via a Bluetooth (registered trademark) unit. The mobile terminal 200 determines that the saddle-type vehicle 100 has fallen over when wireless communication between the saddle-type vehicle 100 and the wearable terminal 500 is interrupted. Note that the mobile terminal 200 makes this determination while the saddle-type vehicle 100 is traveling, so it receives information indicating the moving speed of the saddle-type vehicle, and makes the above-mentioned determination when the received moving speed is equal to or greater than a predetermined speed. If it is determined that the vehicle has fallen over, the mobile terminal 200 acquires various information from the saddle-type vehicle 100, the wearable terminal 500, and its own device, and notifies a predetermined contact of the fact that the vehicle has fallen over 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, blood oxygen, and arm movements, and transmits the detected biological information to the mobile terminal 200 via wireless communication (e.g., Bluetooth communication). Information indicating that communication between the saddle riding vehicle 100 and the wearable terminal 500 has been interrupted is transmitted to the mobile terminal 200 from the one of the saddle riding vehicle 100 and the wearable terminal 500 that maintains communication with the mobile terminal 200.

In this way, in this system, the mobile terminal 200 collects various information, determines if the saddle-type vehicle 100 has rolled over, and reports the event via wideband wireless communication. This eliminates the need to provide a separate unit for wideband wireless communication in the saddle-type vehicle 100, and allows for convenient reporting.

<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 able to swing freely on the main frame 31. The lower end of the cushion unit 94 is supported so as to be able to swing freely on 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, the wearable terminal 500, 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 communication 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-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 communication unit 103 that the saddle riding vehicle 100 has overturned.

The communication unit 103 is a unit that performs wireless communication and transmits and receives signals with the mobile terminal 200 and the wearable terminal 500. The communication unit 103 is, for example, a Bluetooth unit that transmits and receives signals via short-range wireless communication (Bluetooth communication). The communication unit 103 is started when the saddle-riding vehicle 100 is started, and communicates with the mobile terminal 200 and the wearable terminal 500. The wireless communication may be, for example, a wireless LAN (Wi-Fi), Bluetooth, NFC, infrared communication, or any other 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.

When communication between the saddle riding vehicle 100 and the wearable terminal 500 (hereinafter referred to as the first communication or the first communication state) is interrupted, the communication unit 103 transmits information indicating that the first communication has been interrupted to the mobile terminal 200. In this embodiment, whether each communication state has been interrupted is determined based on the communication strength measured by the RSSI value, and when the measured RSSI value becomes equal to or lower than a predetermined threshold, the communication state is determined to have been interrupted. Here, the value of the threshold is not particularly limited, and may be, for example, -60 dBm, -80 dBm, or -90 dBm, and a desired value can be set. As described above, whether the communication state has been interrupted between the saddle riding vehicle 100, the mobile terminal 200, and the wearable terminal 500 is determined, but the criteria for each determination do not need to be unified. For example, the threshold used for the determination may be different for each communication, and the method of measuring the communication state is not limited as long as it is possible to detect a deterioration in the communication state.

In this embodiment, the horn 105 sounds an alarm in response to a loss of wireless communication between the saddle riding vehicle 100 and the wearable device 500 (i.e., detection of a fall of the saddle riding vehicle 100). Note that, although an example of an alarm using only sound will be described, this is not intended to limit the present invention, and instead of or in addition to an alarm using 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 is transmitted to the mobile terminal 200 periodically or irregularly via wireless communication. In addition, the vehicle speed sensor 106 may have other speeds related to the saddle-type vehicle 100, such as an acceleration sensor that detects acceleration in the forward/rearward, left/right, and up/down directions of the vehicle 100, or an angular velocity sensor that detects angular velocities in the roll, pitch, and yaw directions of the vehicle 100, and various speed information may be stored in the memory unit 104. The speed, acceleration, and angular velocity of the saddle riding vehicle 100 are collectively referred to as information relating to the vehicle speed, but in each process of this embodiment, information indicating the moving speed of the saddle riding vehicle 100 is basically used. As described above for the moving speed, the information indicating the speed of the saddle riding vehicle 100 is transmitted to the mobile terminal 200 periodically or irregularly via wireless communication, and is used as a criterion for determining whether or not to determine the communication state. Note that the mobile terminal 200 may be equipped with a speed sensor (not shown), and the moving speed measured by the speed sensor may be used as the moving speed of the saddle riding vehicle 100.

The GPS 107 acquires the current position of the saddle riding vehicle 100. In this embodiment, the GPS 205 included in the mobile terminal 200 acquires the current position of the mobile terminal 200, and the information indicating the acquired current position can be included in the report issued when a fall is determined. Here, the current position of the saddle riding vehicle 100 acquired by the GPS 107 may be used instead of the current position of the mobile terminal 200. In this case, in this system, when a fall is determined, communication between the mobile terminal 200 and the saddle riding vehicle 100 is cut off, so information indicating the current position of the saddle riding vehicle 100 is transmitted to the mobile terminal 200 periodically or irregularly, and the information received immediately before the fall is determined is used. Similarly, information indicating the current position acquired by the GPS (not shown) included in the wearable terminal 500 may be used as position information at the time of the fall.

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 vehicle 100. The mobile terminal 200 can be mounted and fixed to the saddle riding vehicle 100, for example, by a smartphone holder (not shown) provided on the saddle riding vehicle 100. If a fall occurs in this state, the distance between the mobile terminal 200 and the saddle riding vehicle 100 does not change significantly, but the distance between them and the wearable terminal 500 worn by the rider increases significantly, and the state of wireless communication between the terminals is considered to deteriorate. From this perspective, the mobile terminal 200 according to this embodiment determines that the saddle riding vehicle 100 has fallen over in response to receiving information from either the saddle riding vehicle 100 or the wearable terminal 500 indicating that communication between the saddle riding vehicle 100 and the wearable terminal 500 has been interrupted.

Here, the configuration necessary for implementing 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 memory 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 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 wireless device 206. The GPS 205 acquires the current position of the mobile terminal 200. This makes it possible to, for example, provide position information when reporting. The wireless device 206 can send and receive signals to and from the saddle-type vehicle 100 and the wearable terminal 500 via wireless communication. The 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 or the wearable terminal 500. The communication connection with the saddle-type vehicle 100 is established when the saddle-type vehicle 100 is started. For example, the mobile device 200 and the wearable device 500 are paired in advance, and a communication connection is established when the wearable device 500 is started up.

In this embodiment, the control unit 201 determines that the saddle riding vehicle 100 has fallen over when it acquires information indicating that communication between the saddle riding vehicle 100 and the wearable terminal 500 has been interrupted. For example, the control unit 201 may measure the communication strength (radio wave strength) of the signal from the saddle riding vehicle 100 by the wireless device 206 as an RSSI value as described above, and determine that communication has been interrupted when the measured RSSI value becomes equal to or less than a predetermined threshold value.

Here, the higher the antenna output of the wireless communication for detecting a fall, the less likely the communication is to be interrupted, and the lower the antenna output, the more likely the communication is to be interrupted. In view of this, the control unit 201 may adjust the antenna output according to the situation. For example, once communication (first communication) between the saddle riding vehicle 100 and the wearable terminal 500 has been established, the antenna output of the first communication may be lowered in order to more accurately detect any subsequent falls. Also, for example, the antenna output may vary according to the moving speed of the saddle riding vehicle 100. In this case, the antenna output of the first communication may be lowered the faster the moving speed of the saddle riding vehicle 100, from the viewpoint that the faster the moving speed, the more likely it is that a dangerous state will arise in the event of a fall. Further, for example, if it is determined that communication has been interrupted and the antenna output of the first communication is not maximum, the control unit 201 may instruct the saddle riding vehicle 100 or the wearable terminal 500 to increase the antenna output and then determine whether communication has been interrupted again, and if the antenna output is maximum, it may determine that the saddle riding vehicle 100 has fallen. According to such processing, it is possible to determine that a fall has occurred when communication is still interrupted after the antenna output of the first communication is increased to the maximum level that can be confirmed, without immediately determining that communication has been interrupted. These antenna output adjustment processes may be performed spontaneously by the communication unit 103 of the saddle riding vehicle 100 or the data communication unit 502 of the wearable terminal 500, or may be performed in response to an instruction from the control unit 201. Furthermore, these antenna output adjustment processes may be performed in the same manner in wireless communication between the saddle riding vehicle 100 and the mobile terminal 200, and in wireless communication between the wearable terminal 500 and the mobile terminal 200.

The display operation unit 204 is, for example, a touch panel type liquid crystal display, and can perform various displays and accept user operations. The display operation unit 204 displays selectable operation objects for stopping the reporting when a fall is detected. 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 has occurred but the rider can move without any problems. Note that the reception of user operations is not limited to via the operation object, and for example, instead of operating the operation object, the reporting may be stopped when the fall detection sensor 102 detects that the saddle riding vehicle 100, whose communication has been restored, has been raised from a fallen state. In addition, the period during which the reporting stop operation is permitted 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 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 when the vehicle falls while traveling. For example, the control unit 201 may receive an instruction to stop reporting by voice input via a microphone (not shown), or may receive an instruction to stop reporting in response to detecting an operation such as pressing a mechanical switch (e.g., a handlebar switch) provided on the saddle-type vehicle 100.

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 208 (for example, after the alarm sound, "A fall has occurred on the motorcycle! Help please"). Voice synthesis makes it possible to more clearly communicate to the surroundings what is happening.

The wearable terminal 500 is a mobile terminal worn by the rider, such as a smart watch worn by the rider. The wearable terminal 500 includes a biological information detection sensor 501 and a data transmission unit 502. When the first communication is interrupted, the data transmission unit 502 of the wearable terminal 500 transmits information indicating that the first communication has been interrupted to the mobile terminal 200. 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 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. When a fall is detected, the rider of the saddle-type vehicle 100 can choose to report or stop reporting via the wearable device 500, but a detailed explanation will be given later with reference to FIG. 11.

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 responds to a voice call. This is because it is assumed that the rider is unable to make a call due to some reason when the rider falls over. The automatic voice may be repeated multiple times to allow the other party to hear the call. For example, the reporting unit 207 may make a call using the 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 may include, for example, that the voice is an automatic voice, that a fall accident may occur, the address of the place where the accident occurred, the time of the accident, the vehicle speed and acceleration of the saddle-type vehicle 100 immediately before the accident, the rider's name, age, blood type, family contact information, biological information, etc.

Normal voice calls may be made via the mobile device 200 or the wearable device 500. In the event of a fall, there is a risk that the mobile device 200 may become separated from the rider, so a setting may be made such that a voice call is first attempted via the wearable device 500, and then a voice call is attempted via the mobile device 200.

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.

<Communication connection of this system>
5A and 5B are diagrams showing communication connection relationships among devices in the reporting system according to this embodiment. As shown in Fig. 5A, the mobile terminal 200 plays a central role in this reporting system.

The mobile terminal 200 establishes wireless communication such as Bluetooth communication with the communication unit 103 of the saddle riding vehicle 100 and the data communication unit 502 of the wearable terminal 500. Hereinafter, the communication (state) between the wireless device 206 and the communication unit 103 of the mobile terminal 200 will be referred to as the second communication (state), and the communication (state) between the wireless device 206 and the data communication unit 502 will be referred to as the third communication (state). The second communication is established when the saddle riding vehicle 100 is started up, and is used to send and receive information indicating the travel 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 third communication is established when the wearable terminal 500 is started up, and is used to send and receive biological information of the rider, etc.

Furthermore, the mobile terminal 200 can communicate with each of the external devices 300, 400, and 600 via broadband wireless communication (fourth 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.

As described above, in this system, when the first communication between the saddle-type vehicle 100 and the wearable terminal 500 is interrupted, information indicating that is transmitted to the mobile terminal 200 via the second communication or the third communication. The mobile terminal 200 can obtain information indicating that the first communication has been interrupted from either the second communication or the third communication, taking into account that in addition to the first communication, either the second communication or the third communication has been interrupted.

Figure 5B is a diagram showing the system when the first communication and the second communication are interrupted. In this example, for example, the mobile terminal 200 is fixed to the saddle riding vehicle 100, and the first communication and the second communication are interrupted as a result of the vehicle falling over. In this case, the mobile terminal 200 receives information indicating that the first communication has been interrupted from the saddle riding vehicle 100 via the third communication. Next, since the second communication has been interrupted, the mobile terminal 200 transmits information including the latest biological information of the rider previously received from the wearable terminal 500 to the external device via the fourth communication.

Figure 5C is a diagram showing the system when the first communication and the third communication are interrupted. In this example, for example, the rider of the saddle-type vehicle 100 is wearing the mobile device 200, and the first communication and the third communication are interrupted as a result of the rider falling over. In this case, the mobile device 200 receives information indicating that the first communication has been interrupted from the mobile device 200 via the second communication. Next, since the second communication has not been interrupted, the mobile device 200 receives the rider's biometric information at the current time from the wearable device 500, and transmits information including the biometric information to an external device via the fourth communication.

Whether the second communication or the third communication has been interrupted is determined by the control unit 201 in the same manner as the first communication. In this way, by determining that the vehicle has fallen over if the second communication or the third communication has been interrupted in addition to the first communication being interrupted, it is possible to more accurately detect the fall of the saddle riding vehicle 100 and transition to reporting processing.

<Processing procedure of mobile terminal>
6 is a flowchart showing the basic flow of processing steps in the mobile terminal 200 according to this embodiment when the mobile terminal 200 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 the storage unit 202 into the RAM and executing it. The mobile terminal 200 according to this embodiment periodically or irregularly acquires information indicating the traveling speed of the saddle riding type vehicle 100, and starts processing from S604 onwards by acquiring information indicating that the first communication has been interrupted. Note that the number following S indicates the step number of each process.

First, in S601, the control unit 201 of the mobile terminal 200 establishes a communication connection (second connection) with the communication unit 103 of the saddle riding vehicle 100 via the wireless device 206 when the saddle riding vehicle 100 is started. Also, the control unit 201 establishes a communication connection (third connection) with the data communication unit 502 of the wearable terminal 500 via the wireless device 206 when the wearable terminal 500 is started. In S601, either the second connection or the third connection may be established first. Next, in S602, the control unit 201 determines whether or not information has been received from the saddle riding vehicle 100 via the second communication established in S601. If no information has been received, the determination in S602 is repeated. Here, the control unit 201 receives information indicating the moving speed of the saddle riding vehicle 100 and proceeds to S603. In S603, the control unit 201 determines whether or not the moving speed of the saddle riding vehicle 100 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 10 km/h, for example, to detect a fall that occurs while driving. If the speed is equal to or greater than the predetermined value, the process proceeds to S604 to wait for detection of a fall, and if the speed is not equal to or greater than the predetermined value, the process returns to S602.

In S604, the control unit 201 acquires information indicating that the first communication has been interrupted in order to detect a fall of the saddle riding vehicle 100. In S605, the control unit 201 determines whether the antenna output in the first communication is at maximum. If the antenna output is at maximum, the process proceeds to S607, otherwise the process proceeds to S606. In S606, the control unit 201 issues an instruction to the saddle riding vehicle 100 or the wearable terminal 500 to increase the antenna output, and returns the process to S602 before waiting again for detection of a fall. In S607, the control unit 201 executes a process at the time of a fall, and ends the process. Details of the process at the time of a fall will be described later with reference to FIG. 8.

If it is determined that a fall has occurred when the second or third communication has been interrupted in addition to the first communication being interrupted, the control unit 201 detects that the second or third communication has been interrupted in addition to acquiring information indicating that the first communication has been interrupted in S604. That is, the process waits in S604 until the first communication and the second or third communication are interrupted. In this case, in S605, it is determined whether or not the antenna outputs of the interrupted communications are both maximum, and if both are maximum, the process proceeds to S607, and if not, the antenna output whose output is not maximum is increased in S606.

<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, when the saddle riding vehicle 100 is started, the control unit 101 of the saddle riding vehicle 100 establishes a wireless communication connection with the mobile terminal 200 and the wearable terminal 500 via the communication unit 103. Next, in S702, the control unit 101 stores the moving speed of the saddle riding vehicle 100 acquired by the vehicle speed sensor 106 in the memory unit 104 and transmits it to the mobile terminal 200 via wireless communication. The transmission may be periodic or irregular.

Next, in S703, the control unit 101 determines whether the first communication, which is a communication connection with the wearable terminal 500, has been interrupted. If the first communication has not been interrupted, the process returns to S702. On the other hand, if the first communication has been interrupted, the process proceeds to S704, where the control unit 101 performs processing for when the vehicle has rolled over, and ends the process. The processing for when the vehicle has rolled over is processing for notifying the surroundings that the saddle-riding vehicle 100 has rolled over, such as an alarm processing for sounding the horn 105. When the horn 105 is sounded, the control unit 101 may stop the sound in response to an operation of an operation object (similar to a stop button 1003 described later) displayed on the meter panel MP of the saddle-riding vehicle 100. In addition, when the communication with the wearable terminal 500 is restored after the detection of the fall, the control unit 101 may end the horn sounding processing by stopping the notification via a GUI as shown in FIG. 10 described later. In addition, in this system, a situation may occur in which the first communication is interrupted but the second communication is not interrupted. In that case, the process performed by the control unit 101 as shown in FIG. 7 may be performed by instructions from the control unit 201 of the mobile terminal 200.

<Details of how the mobile device handles falls>
8 is a flowchart showing the detailed procedure of the above-mentioned fall-time processing in S607 in the mobile terminal 200 according to this embodiment. 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.

When information indicating that the first communication has been interrupted is acquired in S604, the control unit 201 outputs an alarm sound from the speaker 208 in S801. Furthermore, in S802, the control unit 201 acquires information on a preset contact to be made in the event of a fall from the storage unit 202. Furthermore, in S803, the control unit 201 displays a report stop screen 1000 including an operation object described later on the display operation unit 204. Details of the report stop screen 1000 will be described later with reference to FIG. 10. Note that there is no intention to particularly limit the order of the processes from S801 to S803, and any order may be used.

Next, in S804, the control unit 201 determines whether or not a notification stop operation has been received by operating the above-mentioned 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 notification stop screen 1000, the control unit 201 determines that a stop operation has not been received and proceeds to notification processing. In addition, the above-mentioned 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 has repositioned the saddle-type vehicle 100 that has fallen. Regarding the repositioning of the saddle-type vehicle 100, for example, when communication with the saddle-type vehicle 100 is restored, the determination may be triggered by the stop of the signal input from the fall detection sensor 102. In S808, the control unit 201 stops outputting the alarm sound that was being output and ends the process.

On the other hand, in S805, the control unit 201 acquires the rider's biometric information from the wearable terminal 500. Here, if the third communication is interrupted, the control unit 201 may acquire the latest biometric information acquired through the third communication as the rider's biometric information, and if the third communication is not interrupted, may transmit a request to transmit the biometric information to the wearable terminal 500. Next, in S806, the control unit 201 acquires current position information via the GPS 205. Then, in S807, the control unit 201 notifies a previously set contact 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, the 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.

<Settings screen>
9 shows an example of a contact setting screen 900 displayed on the mobile terminal 200 according to this embodiment. The setting screen 900 is displayed on the display operation unit 204. Note that the setting screen 900 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. 9, the setting screen 900 includes setting fields for emergency contact 901, user-defined telephone contact setting 902, and user-defined email destination setting 904. Each setting field can be set by inputting the corresponding contact. In addition, "119" is preset as the default setting for emergency contact 901. The setting screen 900 further includes add buttons 903 and 905 corresponding to contact setting 902 and destination setting 904, respectively. When each of the add buttons 903 and 905 is selected, the number of setting fields for the contact and destination can be increased.

The setting screen 900 also includes an OK button 906 and a cancel button 907. When the OK button 906 is selected, the contacts and other information set on the setting screen 900 are finalized and stored in the storage unit 202. On the other hand, when the cancel button 907 is selected, the contacts and other information set on the setting screen 900 are cancelled and the setting information is not changed.

<Report stop screen (mobile device)>
10 shows an example of a notification stop screen 1000 displayed on the mobile terminal 200 according to this embodiment. The notification stop screen 1000 is displayed on the display operation unit 204. Note that a screen equivalent to the notification stop screen 1000 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.

10, the report stop screen 1000 includes a display indicating that a report will be sent to the contact 1001 and the destination 1002 after a predetermined time (30 seconds in this case) has elapsed since a fall of the motorcycle, which is the saddle-riding 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 1000 includes a stop button 1003 and a report button 1004. When the stop button 1003 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 vehicle 100 that the stop operation has been accepted. Also, when the report button 1004 is selected, the mobile terminal 200 starts the report processing without waiting for the predetermined time to elapse. The stop button 1003 is an example of a first operation object. Also, the second operation object displayed on the meter panel MP of the saddle-riding vehicle 100 is equivalent to the stop button 1003. Furthermore, a button corresponding to the report button 1004 may be displayed on the meter panel MP. It is also desirable for the stop button 1003 to 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 stop screen (wearable device)>
In addition, when the mobile terminal 200 is fixed to the saddle riding type vehicle 100, it is considered that the wearable terminal 500 is the only terminal in the rider's hand when a fall occurs. In consideration of such a situation, a notification stop instruction similar to that shown in Fig. 10 may be issued by the wearable terminal 500. Fig. 11 shows an example of a notification stop screen 1100 displayed on the wearable terminal 500.

11, a GUI is displayed on the report stop screen 1100 to select whether or not to report because the saddle riding vehicle 100 has been detected to have fallen over. Here, the wearable terminal 500 performs a report process when it receives a selection by the rider to report or when a predetermined time has elapsed without receiving a stop instruction. The configuration in which the wearable terminal 500 receives an operation from the rider is not particularly limited. For example, the wearable terminal 500 may receive an operation from the rider via, for example, a touch operation on the stop button 1101 or the report button 1102 on the report stop screen 1100, may receive the operation via a switch 1103 corresponding to the stop process or a switch 1104 corresponding to the report process, or may receive the operation as a selection operation of stop/report by rotating a dial switch. Note that the report stop screen 1100 displays only the stop button 1101 and the report button 1102 in consideration of visibility according to the size of the display, but may display all information similar to that of the report stop screen 1000 in FIG. 10.

<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 904, which is set in advance in the user settings of the setting screen 900. 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.

Second Embodiment
<Rider Physical Abnormality Detection Processing>
The second embodiment of the present invention will be described below. The information processing device according to the first embodiment was able to determine that a fall had occurred in response to the interruption of the first communication, and to notify the external device. In addition, the control unit 201 of the mobile terminal 200 according to this embodiment determines whether or not the rider has a physical abnormality based on the rider's biological information received from the wearable terminal 500. Next, when the control unit 201 determines that the rider has a physical abnormality, it notifies the external device by the same process (e.g., S807) as when a fall has occurred in the first embodiment. Furthermore, when the control unit 201 determines that the rider has a physical abnormality, it may reduce the output of the power source (engine) of the saddle riding type vehicle 100. That is, when an abnormality is observed in the rider's physical condition, the mobile terminal 200 according to this embodiment determines that the rider is in a dangerous state similar to a fall, and performs various response processes.

The control unit 201 according to the present embodiment judges whether or not the rider has a physical abnormality based on the biometric information. The biometric information used here is heart rate, blood pressure, electrocardiogram, blood oxygen, etc., but is not limited to these as long as it can determine the rider's health condition. The control unit 201 judges that a physical abnormality has occurred when the biometric information indicates an abnormal value. Here, the abnormal value in the biometric information may be set in advance, or may be set based on the measured values of the rider for a predetermined period obtained from the wearable terminal 500 (for example, a value that is different from the average of the measured values by a predetermined value or more may be set as an abnormal value). The heart rate that is determined to be an abnormal value by the control unit 201 may be, for example, 60 or less, 50 or less, 40 or less, 100 or more, 110 or more, or 120 or more. The systolic blood pressure that is determined to be an abnormal value by the control unit 201 may be 130 or more, 150 or more, 170 or more, 10 or less, 90 or less, or 80 or less. The diastolic blood pressure that is determined to be an abnormal value by the control unit 201 may be 90 or more, 100 or more, or 110 or more. Furthermore, the control unit 201 may determine that an abnormal value is present when the excitation wave indicated by the electrocardiogram shows an abnormal transition. This may be the case when an electrocardiogram change characteristic of a known disease such as arrhythmia or electrolyte abnormality is observed, or may be an abnormal value based on the rider's electrocardiogram for a predetermined period of time. The blood oxygen concentration that is determined to be an abnormal value by the control unit 201 may be, for example, less than 96%, less than 95%, less than 94%, or less than 93%. In this way, when the rider's biological information measured by the wearable terminal 500 is a value that is generally considered to be abnormal regardless of the type, the control unit 201 determines that a physical abnormality has occurred in the rider and notifies the rider by reducing the engine output.

The control unit 201 may determine whether a physical abnormality has occurred based on information acquired from the wearable terminal 500, or the wearable terminal 500 may determine whether a physical abnormality has occurred and acquire information indicating the determination result. When the wearable terminal 500 makes the determination, the same process as the determination performed by the control unit 201 described above is performed.

Figure 13 is a flowchart showing the procedure of the abnormality detection process 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. The process shown in Figure 13 is performed while waiting for detection of a fall in S604 according to the first embodiment.

In S1301, the control unit 201 acquires the rider's biometric information. Here, the control unit 201 may transmit a signal requesting the biometric information to the wearable terminal 500, or may refer to the most recent biometric information currently received from the wearable terminal 500. In S1302, the control unit 201 determines whether or not there is a physical abnormality in the rider of the saddle-type vehicle 100 based on the biometric information acquired in S1301. If there is a physical abnormality, the process proceeds to S1303, and if not, the process returns to S1301.

In S1303, the control unit 201 reduces the output of the engine 21 of the saddle riding type vehicle 100. Next, in S1304, the control unit 201 acquires current position information via the GPS 205 in the same manner as in S806. Then, in S1305, the control unit 201 notifies a pre-set contact of the occurrence of a physical abnormality in the rider, a value indicating the physical abnormality, and, as necessary, position information, vehicle speed information, and the like, and ends the process. The notification process in S1305 can be performed in the same manner as the notification process in S807 in the first embodiment, except that information regarding the physical abnormality is notified instead of the occurrence of a fall.

This type of processing makes it possible for the mobile device to handle any physical abnormality detected in the rider while the saddle-type vehicle is in motion.

Summary of the embodiment
The above embodiment discloses at least the following program, information processing method, and system.

1. The program of the above embodiment is
A saddle-type vehicle (e.g., 100) and a second portable terminal (e.g., 200) capable of wireless communication with a first portable terminal (e.g., 500),
a receiving step (e.g., S602) of receiving information indicating a traveling speed of the saddle riding type vehicle from the saddle riding type vehicle;
an acquisition step (e.g., S604) of acquiring information indicating a first communication state, which is a communication state between the saddle riding type vehicle and the first portable terminal;
a rollover determination step (e.g., S604) of determining that the saddle riding type vehicle has rolled over when the moving speed of the saddle riding type vehicle based on the information received in the receiving step is equal to or higher than a predetermined speed and the first communication state is interrupted;
Execute the command.
According to this embodiment, the mobile terminal 200 can detect a fall of the saddle riding type vehicle 100 depending on whether or not communication between the mobile terminal 200 and the wearable terminal 500 has been interrupted. In addition, since the mobile terminal 200 can determine the fall, a report can be sent by using a communication function of the mobile terminal 200 such as a smartphone.

2. In the above embodiment,
a first communication state determination step (e.g., S604) of determining a second communication state which is a communication state with the saddle riding type vehicle;
A second communication state determination step (e.g., S604) of determining a third communication state which is a communication state with the first portable terminal;
Further equipped with
In the falling determination step,
When the first communication state determination step determines that the second communication state has been interrupted and the first communication state is also interrupted, or when the second communication state determination step determines that the third communication state has been interrupted and the first communication state is also interrupted,
It is determined that the saddle type vehicle has fallen over.
According to this embodiment, a fall can be detected more accurately by determining that a fall has occurred not only when communication between the mobile terminal 200 and the wearable terminal 500 is lost, but also when communication from the mobile terminal 200 to the saddle-type vehicle 100 or the wearable terminal is lost.

3. In the above embodiment,
the first communication state determination step further includes a first lowering step of lowering an antenna output for wireless communication with the saddle riding type vehicle when it is determined that communication with the saddle riding type vehicle is being established,
the second communication state determination step further includes a second lowering step of lowering an antenna output of wireless communication with the first portable terminal when it is determined that communication with the first portable terminal is being established;
The method further includes a third lowering step of lowering the antenna output of the wireless communication between the saddle-type vehicle and the first portable terminal when it is determined that communication between the saddle-type vehicle and the first portable terminal is taking place in the acquisition step.
According to this embodiment, by lowering the antenna output after starting communication, it becomes possible to detect a fall more accurately.

4. In the above embodiment,
The antenna output for wireless communication with the saddle-type vehicle, the antenna output for wireless communication with the first portable terminal, or the antenna output for wireless communication between the saddle-type vehicle and the first portable terminal is varied depending on the moving speed of the saddle-type vehicle.
According to this embodiment, it is possible to vary the accuracy of the fall detection depending on the risk caused by the travel speed of the saddle riding type vehicle 100 .

5. In the above embodiment,
The antenna output for wireless communication with the saddle-type vehicle, the antenna output for wireless communication with the first portable terminal, or the antenna output for wireless communication between the saddle-type vehicle and the first portable terminal decreases as the moving speed of the saddle-type vehicle increases.
According to this embodiment, it is possible to improve the accuracy of the fall detection as the travel speed of the saddle riding type vehicle 100 increases, that is, as the risk of falling increases.

6. In the above embodiment,
