DETAILED DESCRIPTION

[0031] Hereinafter, the embodiments are described in detail with reference to the accompanying drawings. Moreover, the following embodiments are not intended to limit the scope of the claims to be protected, and the present invention does not require the combination of all the features described in the embodiments. It is also possible to arbitrarily combine two or more of the multiple features described in the embodiments. In addition, the same figure mark is added to the same or similar structure, and repeated descriptions are omitted.

[0032] In each figure, the arrow symbols X, Y, and Z indicate mutually orthogonal directions, the X direction indicates the front-to-back direction of the saddle-type vehicle, the Y direction indicates the vehicle width direction (left-right direction) of the saddle-type vehicle, and the Z direction indicates the up-down direction. The left and right of the saddle-type vehicle are the left and right when viewed along the forward direction. In the following, the front or rear of the saddle-type vehicle in the front-to-back direction is sometimes referred to as the front or rear. In addition, the inner side or outer side of the saddle-type vehicle in the vehicle width direction (left-right direction) is sometimes referred to as the inner side or outer side.

[0033] <First Embodiment>

[0034] <Overall structure of the notification system>

[0035] Hereinafter, a first embodiment of the present invention will be described. Figure 1 1 is a diagram showing the overall structure of the notification system according to the present embodiment. The system includes a saddle-type vehicle 100, a portable terminal 200, an external device 300, an external device 400, and a wearable terminal 500. The present invention is not limited thereto, and other devices may be included.

[0036] This system detects the fall of the riding vehicle 100, and the portable terminal 200 owned by the rider of the riding vehicle 100 collects various information and notifies the established contact information through broadband wireless communication such as mobile communication (4G, 5G), such as emergency contact information (119 phone), portable terminal of acquaintances, information storage server and other external devices. These established contact information can be set in advance. The external device 300 represents the portable terminal of an acquaintance set as the established contact information, and the external device 400 represents the terminal of the fire department, the terminal of the hospital, etc. connected by the 119 phone.

[0037] The portable terminal 200 receives the detection result of the fall detection sensor 102 provided on the riding vehicle 100 via the Bluetooth (Bluetooth: registered trademark) unit 103 through short-range wireless communication (here, Bluetooth communication) to determine the fall of the riding vehicle 100. In addition, as described in detail later, the portable terminal 200 receives information related to the vehicle speed from the riding vehicle 100 periodically or irregularly. The information related to the vehicle speed is used to determine whether a significant difference is generated compared with the vehicle speed determined by the sensor provided on the portable terminal 200. For example, when a fall occurs, when the rider is physically separated from the riding vehicle 100, there is a possibility that the short-range wireless communication between the portable terminal 200 and the riding vehicle 100 is cut off. In this case, there is a concern that the detection result of the fall detection sensor 102 mentioned above cannot be received in the portable terminal 200. Even in such a situation, the fall detection is determined by determining the above-mentioned significant difference. When a fall is determined, the portable terminal 200 obtains various information from the riding vehicle 100, the wearable terminal 500, and the device, and notifies the predetermined contact information of the fall and the acquired information. The wearable terminal 500 is a smart watch worn by the rider of the riding vehicle 100, and can detect the rider's heart rate, blood pressure, electrocardiogram, blood oxygen and other biological information, and sends the detected biological information to the portable terminal 200 via short-range wireless communication (e.g., Bluetooth communication).

[0038] Thus, in this system, the portable terminal 200 collects various information, determines the fall of the saddle-type vehicle 100, and notifies through broadband wireless communication. Thus, it is not necessary to separately provide a unit for broadband wireless communication in the saddle-type vehicle 100, and appropriate notification can be made. In addition, according to this embodiment, even if the rider is thrown away from the saddle-type vehicle 100 and separated when falling, and even if the short-range wireless communication between the portable terminal 200 and the saddle-type vehicle 100 is disconnected, the fall can be appropriately determined in the portable terminal 200.

[0039] <Overview of Saddle-type Vehicle>

[0040] Figure 2 FIG. 1 is a side view of the right side of the saddle-ride type vehicle 100 according to one embodiment of the present invention. Figure 3 It is a front view of the saddle-ride type vehicle 100 .

[0041] The riding vehicle 100 is a two-wheeled motor vehicle suitable for traveling over long distances, but the present invention can be applied to various riding vehicles including other forms of two-wheeled motor vehicles, and can also be applied to electric vehicles using a motor as a driving source in addition to vehicles using an internal combustion engine as a driving source. Hereinafter, the riding vehicle 100 is sometimes referred to as vehicle 100. In addition, in the present embodiment, a two-wheeled riding vehicle is used as an example of a vehicle for explanation, but the present invention is not limited thereto, and can be applied to various vehicles such as four-wheel drive vehicles.

[0042] The vehicle 100 includes a power unit 2 between the front wheels FW and the rear wheels RW. In the present embodiment, the power unit 2 includes a horizontally opposed six-cylinder engine 21 and a transmission 22. The driving force of the transmission 22 is transmitted to the rear wheels RW via a drive shaft (not shown) to rotate the rear wheels RW.

[0043] The power unit 2 is supported by a vehicle body frame 3. The vehicle body frame 3 includes a pair of left and right main frames 31 extending in the X direction.

[0044] A head pipe 32 is provided at the front end of the main frame 31, and a wheel shaft (not shown) rotated by the handlebar 8 is supported by the head pipe 32 in a rotatable manner. A pair of left and right pivot plates 33 are provided at the rear end of the main frame 31. The lower end of the pivot plate 33 is connected to the front end of the main frame 31 by a pair of left and right lower arms (not shown), and the power unit 2 is supported by the main frame 31 and the lower arms. In addition, a pair of left and right seat rails (not shown) extending backward are provided at the rear end of the main frame 31, and the seat rails support a seat 4a for a rider, a seat 4b for a fellow passenger, and a trunk 7b.

[0045] The front end of a rear swing arm (not shown) extending in the front-rear direction is supported by a pivot plate 33 in a swingable manner. The rear swing arm can swing in the up-down direction, and the rear end of the rear swing arm supports the rear wheel RW. An exhaust muffler 6 for muffler exhaust of the engine 21 is provided on the lower side of the rear wheel RW extending in the X direction. Left and right side bags 7a are provided on the upper side of the rear wheel RW.

[0046] A front suspension mechanism 9 that supports the front wheel FW is formed 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 body 93, a shock absorbing unit 94, and a pair of left and right front forks 95.

[0047] The upper link 91 and the lower link 92 are arranged at a distance from each other in the vertical direction at the front end of the main frame 31. The rear ends of the upper link 91 and the lower link 92 are connected to the support portion provided at the front end of the main frame 31 in a swingable manner. The front ends of the upper link 91 and the lower link 92 are connected to the fork support body 93 in a swingable manner. The upper link 91 and the lower link 92 extend in the front-rear direction and are arranged substantially in parallel.

[0048] The shock absorber 94 has a structure in which a shock absorber is inserted through a coil spring, and the upper end of the shock absorber 94 is swingably supported by the main frame 31. The lower end of the shock absorber 94 is swingably supported by the lower link 92.

[0049] The fork support body 93 is cylindrical and tilted rearward. The front end of the upper link 91 is rotatably connected to the upper front portion of the fork support body 93. The front end of the lower link 92 is rotatably connected to the lower rear portion of the fork support body 93.

[0050] The wheel shaft 96 is supported by the fork support body 93 in a manner that allows it to rotate freely around its axis. The wheel shaft 96 has a shaft portion (not shown) through which the fork support body 93 is inserted. A bridge portion (not shown) is provided at the lower end of the wheel shaft 96, and a pair of left and right front forks 95 are supported on the bridge portion. The front wheel FW is supported by the front fork 95 in a manner that allows it to rotate freely. The upper end of the wheel shaft 96 is connected to a steering shaft (not shown) that is rotated by the handlebar 8 via a connecting member 97. The wheel shaft 96 is rotated by the turning of the handlebar 8, so that the front wheel FW turns.

[0051] The vehicle 100 includes a brake device 19F for braking the front wheel FW and a brake device 19R for braking the rear wheel RW. The brake device 19F and the brake device 19R are configured to be actuated by the rider operating the brake handle 8a or the brake pedal 8b. The brake device 19F and the brake device 19R are, for example, disc brakes. When the brake device 19F and the brake device 19R are not distinguished, they are collectively referred to as the brake device 19.

[0052] A headlamp 11 is disposed at the front of the vehicle 100 to irradiate light toward the front of the vehicle 100. The headlamp 11 of the present embodiment is a dual-lamp headlamp unit having a right light irradiation portion 11R and a left light irradiation portion 11L symmetrically. However, a single-lamp or three-lamp headlamp unit or a dual-lamp headlamp unit that is asymmetrical may also be employed.

[0053] The front of the vehicle 100 is covered by a cowl 12, and the front side of the vehicle 100 is covered by a pair of left and right side cowls 14. A windshield 13 is arranged above the cowl 12. The windshield 13 is a windshield that reduces the wind pressure on the rider during driving, and is formed of, for example, a transparent resin member.

[0054] A pair of left and right side mirror units 15 are disposed on the sides of the cowl 12. The side mirror units 15 support side mirrors (not shown) for the rider to observe the rear.

[0055] In the present embodiment, the front cowl 12 is composed of enclosure members 121 to 123. The enclosure member 121 extends in the Y direction to form a main body of the front cowl 12, and the enclosure member 122 forms an upper portion of the enclosure member 121. The enclosure member 123 is disposed below and away from the enclosure member 121.

[0056] An opening for exposing the headlight 11 is formed between the enclosure member 121 and the enclosure member 123 and between the pair of left and right side enclosures 14 . The upper edge of the opening is defined by the enclosure member 121 , the lower edge of the opening is defined by the enclosure member 123 , and the left and right side edges of the opening are defined by the side enclosures 14 .

[0057] A camera unit 16A and a radar unit 16B are arranged behind the front enclosure 12 as detection equipment for detecting the situation in front of the vehicle 100. The radar unit 16B is, for example, a millimeter wave radar. The camera unit 16A includes: a camera element such as a CCD (Charge Coupled Device) image sensor, a CMOS (Complementary Metal Oxide Semiconductor) image sensor; and an optical device such as a lens, and captures an image in front of the vehicle 100. The camera unit 16A is arranged behind a surrounding member 122, and the surrounding member 122 constitutes the upper part of the front enclosure 12. An opening 122a is formed in the surrounding member 122 to penetrate the surrounding member 122, and the camera unit 16A captures an image in front of the vehicle 100 through the opening 122a.

[0058] The radar unit 16B is disposed behind the enclosure member 121. The enclosure member 121 makes the detection unit (external monitoring device) 16 less noticeable when the vehicle 100 is viewed from the front, thereby preventing the appearance of the vehicle 100 from being deteriorated. The enclosure member 121 is made of a material such as resin that can transmit electromagnetic waves.

[0059] When the vehicle is viewed from the front, the camera unit 16A and the radar unit 16B are arranged at the center of the front 12 in the Y direction. By arranging the camera unit 16A and the radar unit 16B at the center of the vehicle 100 in the Y direction, a larger camera range and detection range can be obtained on the left and right sides in front of the vehicle 100, so that 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 equally on the left and right sides by one camera unit 16A and one radar unit 16B, it is particularly advantageous in a structure in which a single unit is provided instead of a plurality of camera units 16A and radar units 16B.

[0060] <Control Structure of Notification System>

[0061] Figure 4 1 is a block diagram showing the control structure of the notification system involved in the present embodiment, and only the necessary structures related to the description described later are shown. The present system is configured to include a riding vehicle 100, a portable terminal 200, an external device 300, an external device 400, an external device 600, and a wearable terminal 500. Moreover, these structures are examples and do not limit the intention of the present invention. For example, it can also be composed of only a riding vehicle 100, a portable terminal 200 and an external device, or it can include more external devices.

[0062] The riding vehicle 100 includes a control unit (ECU) 101, a fall detection sensor 102, a Bluetooth unit 103, a storage unit 104, an electric horn 105, a vehicle speed sensor 106, a GPS 107, and a dashboard MP. The control unit 101 includes a processor represented by a CPU (Central Processing Unit). The storage unit 104 stores programs executed by the processor, data used by the processor in processing, etc. Moreover, the storage unit 104 can also be assembled inside the control unit 101. The control unit 101 can be connected to other components 102 to 106 through signal lines such as a bus and send and receive signals to control the entire riding vehicle 100.

[0063] The instrument panel MP displays various parameters and warnings of the riding vehicle 100 to the rider. In the present embodiment, at least the instrument panel MP displays an operation object (second operation object) for stopping the notification. In addition, if a microphone and a speaker are built into the helmet, the stop operation of the notification can also be guided by voice, and the control is performed in a manner that is accepted by voice input.

[0064] The fall detection sensor 102 has a built-in pendulum component for detecting the tilt of the riding vehicle 100. When the pendulum component tilts at an angle of 60 to 70 degrees, the 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 riding vehicle 100 has fallen and stops the engine. In addition, the control unit 101 notifies the portable terminal 200 of the fall of the riding vehicle 100 via the Bluetooth unit 103. In addition, there is a possibility that the fall detection sensor 102 needs a fixed time to detect the fall, during which the short-range wireless communication with the portable terminal 200 via the Bluetooth unit 103 is cut off. This is because there is a possibility that the rider holding the portable terminal 200 is thrown out of the riding vehicle 100 when falling, and the portable terminal 200 is separated from the riding vehicle 100 and exceeds the range of the short-range wireless communication. If the detection result of the fall detection sensor 102 is received by the portable terminal 200 before the short-range wireless communication is cut off, there is no problem, but if it cannot be received, the portable terminal 200 cannot detect the fall of the riding vehicle 100. Therefore, in the notification involved in this embodiment, the following structure is provided, and the information related to the speed of the riding vehicle 100 is sent to the portable terminal 200 periodically or irregularly in advance, and the fall is detected using this information. The details are described later.

[0065] The Bluetooth unit 103 is an example of a unit that performs short-range wireless communication, and sends and receives signals with the portable terminal 200 via short-range wireless communication (Bluetooth communication). The Bluetooth unit 103 is activated when the riding vehicle 100 is started, and is connected to the portable terminal 200 for communication. Short-range wireless communication can be, for example, a communication method that can communicate within a predetermined range, such as a wireless local area network LAN (Wi-Fi), Bluetooth, near field communication NFC (Near Field Communication), infrared communication, etc. It is desirable that the communication range is set to, for example, an area including a radius of 5m to 20m from the riding vehicle 100, so that even if the riding vehicle 100 falls and the rider is separated from the riding vehicle 100, communication with the portable terminal 200 is ensured within the predetermined range.

[0066] In the present embodiment, the electric horn 105 sounds and warns according to the instruction from the portable terminal 200. In addition, the example in which the alarm is only sound is described, but the present invention is not limited thereto, and the alarm of the electric horn 105 may be replaced or added, for example, by lighting or flashing the headlights 11, turn indicators, etc.

[0067] The vehicle speed sensor 106 detects the vehicle speed of the vehicle 100. The vehicle speed sensor 106 is, for example, a sensor supported by the front fork 95 and detecting the rotation amount of the front wheel FW. The vehicle speed detected by the vehicle speed sensor 106 is stored in the storage unit 104. The storage unit 104 is configured to have a circular buffer, and new vehicle speed information replaces old vehicle speed information. The vehicle speed information stored in the storage unit 104 is periodically or irregularly transmitted to the portable terminal 200 via short-range wireless communication. In addition, the vehicle speed sensor 106 may also include: an acceleration sensor that detects other speeds related to the saddle-type vehicle 100, such as the acceleration of the front-back direction, the left-right direction, and the up-down direction of the vehicle 100; and an angular velocity sensor that detects the angular velocity of the vehicle 100 in the roll direction, the pitch direction, and the yaw direction. The vehicle speed sensor 106 stores various speed information in the storage unit 104. The speed, acceleration, and angular velocity of the saddle-type vehicle 100 are collectively referred to as information related to the vehicle speed. As described above, the information on the vehicle speed is transmitted to the portable terminal 200 periodically or irregularly via short-range wireless communication.

[0068] The GPS 107 acquires the current position of the saddle-type vehicle 100. In addition, the GPS 107 is an option in the present invention. When the GPS 107 is already provided in the saddle-type vehicle 100, in addition to or instead of the information related to the vehicle speed, the position information is used to determine whether there is a significant difference between the position information and the information acquired by the portable terminal 200. As described above, the determination result is used to detect a fall of the saddle-type vehicle 100. Alternatively, when the portable terminal 200 is not provided with a GPS function, the GPS 107 of the saddle-type vehicle 100 is used to acquire the position information at the time of the fall.

[0069] Next, the structure of the portable terminal 200 will be described. The portable terminal 200 represents a portable device such as a smart phone owned by the rider of the riding vehicle 100. Here, the structure required for implementing the present invention will be mainly described. Therefore, in addition to the structure described below, other structures may be included. The portable terminal 200 includes a control unit 201, a storage unit 202, an external communication device 203, a display operation unit 204, a speaker 208, and a speed sensor. The external communication device 203 includes a GPS 205, a short-range wireless device 206, and a notification unit 207.

[0070] The control unit 201 includes a processor represented by a CPU. The storage unit 202 stores programs executed by the processor, data used by the processor in processing, etc. Moreover, the storage unit 202 can also be assembled inside the control unit 201. The control unit 201 can be connected to other components 203, components 204, and components 208 through signal lines such as buses and send and receive signals to control the entire portable terminal 200.

[0071] The control unit 201 uses the notification unit 207 of the external communication device 203 to notify at least one of the external device 300, the external device 400, and the external device 600 via the wide area network. In addition, the control unit 201 obtains various information via the GPS 205 and the short-range wireless device 206. The GPS 205 obtains the current position of the portable terminal 200. Thus, for example, position information can be added when making a notification. The short-range wireless device 206 can send and receive signals with the riding vehicle 100 and the wearable terminal 500 via short-range wireless communication. Short-range wireless communication can be, for example, a communication method that can communicate within a predetermined range, such as a wireless local area network LAN (Wi-Fi), Bluetooth, NFC, infrared communication, etc. As a communication range, for example, it can be set to include an area with a radius of 5m to 20m from the riding vehicle 100. In addition, when the riding vehicle 100 is started, communication connection is made with the riding vehicle 100.

[0072] The display operation unit 204 is, for example, a touch panel type liquid crystal display, which can perform various displays and accept user operations. The display operation unit 204 displays an operation object (first operation object) for stopping the notification when a fall is detected in an optional manner. The operation object can also be displayed on the instrument panel MP of the riding vehicle 100 as described above, and is used to stop the notification when the rider who has fallen is fine and can move. Moreover, the stop of the notification can also be, instead of operating the operation object, stopping the notification when the fall detection sensor 102 detects that the riding vehicle 100 is lifted up from the fallen state. In addition, the period during which the notification is allowed to be stopped can also be dynamically changed according to the vehicle speed (moving speed) at the time of the fall. For example, if the vehicle speed is within 0km~5km, the possibility of the rider being injured is low, and the possibility of the rider lifting the riding vehicle 100 by himself is high, so compared with the case of falling while driving, a longer period can be set as the period for stopping the operation.

[0073] The speaker 208 outputs an alarm sound when a fall is detected. The alarm of the speaker 208 can be stopped by the above-mentioned stop operation of the rider, and can also be stopped by an operation input to another stop button or the like. Furthermore, it is desirable that when a stop screen of a notification described later is displayed on the display operation unit 204 when a fall occurs, an alarm sound is output simultaneously with the display in order to notify the rider of its meaning, and it is also desirable to output the alarm sound at the maximum volume. It is also possible to have a structure that can set the volume in advance. In addition, not only an alarm sound, but also a sound-synthesized message can be played by the speaker (for example, "A motorcycle has fallen! Requesting help" is played after the alarm sound). If it is sound synthesis, what is happening can be conveyed more clearly to the surroundings.

[0074] The speed sensor 209 is an acceleration sensor that detects the acceleration of the portable terminal 200 in the front-back direction, the left-right direction, and the up-down direction. The output value representing the acceleration output from the speed sensor 209 is stored in the circular buffer of the storage unit 202, and the oldest record is replaced. In addition, the required data is the data of the riding vehicle 100 during startup, so it is expected that the riding vehicle 100 is started and the short-distance wireless communication described later is established to start recording the data. The recorded data is used to compare with the information related to the vehicle speed received from the riding vehicle 100 to determine whether a significant difference has occurred.

[0075] The external device 300 represents a pre-set contact method, that is, a terminal for notifying the destination. The external device 300 is, for example, a portable terminal such as a smartphone, and is a terminal owned by an acquaintance registered in advance by the rider. The control structure is the same as that of the portable terminal 200, so the detailed structure is omitted. The content notified by the portable terminal 200 is displayed on the display operation unit 301 of the external device 300. The detailed display content will be described later.

[0076] The external device 400 is a terminal that receives the notification call from the notification unit 207, such as an emergency contact method (119 phone call, etc.). Here, the notification unit 207 may output automatic voice when the external device 400 answers the voice call. This is because it is assumed that the rider cannot talk for some reason when falling. For example, the notification unit 207 may use automatic voice calls as the default setting, and display a switch button for switching from automatic voice to the rider himself talking on the display operation unit 204. When the switch button is operated, the automatic voice ends and switches to a normal voice call. The content of the automatic voice includes, for example, the occurrence of the fall accident, the place of occurrence, the time of occurrence, the biological information of the rider, etc.

[0077] The external device 600 is an example of a data server of the present system, and is a device for storing various information sent from the portable terminal 200. This information is used for accident investigation, etc. The communication method may be, for example, an e-mail, or a communication method capable of sending other information. The received information is stored in the data storage unit 601.

[0078] The wearable terminal 500 is a wearable terminal such as a smart watch worn by the rider, which detects the biological information of the rider and sends it to the portable terminal 200. The wearable terminal 500 has a biological information detection sensor 501 and a data transmission unit 502. The biological information detection sensor 501 detects biological information such as heart rate, blood pressure, electrocardiogram, and blood oxygen of the rider wearing the wearable terminal 500. These biological information can be sent to the portable terminal 200 regularly by the data transmission unit 502, or the latest data at that time can be sent according to the request from the portable terminal 200 when the riding vehicle 100 falls. Moreover, it is expected that, in addition to the latest data at that time, biological information is also detected and sent in a fixed period thereafter when there is a request from the portable terminal 200. In this way, changes in the physical condition of the rider when he falls can be detected.

[0079] <Communication connection of this system>

[0080] Figure 5 1 is a diagram showing the communication connection relationship between the various devices of the notification system involved in this embodiment. Figure 5 As shown, the portable terminal 200 plays the role of the center of this notification system.

[0081] The portable terminal 200 establishes short-range wireless communication (first communication) such as Bluetooth communication with the Bluetooth unit 103 of the riding vehicle 100. This communication is established when the riding vehicle 100 is started, and is used to send and receive information related to the vehicle speed during driving, the meaning of a fall detected by the fall detection sensor 102, and various information. In addition, the portable terminal 200 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, and sends and receives biological information of the rider, etc.

[0082] Furthermore, the portable terminal 200 can communicate with the external device 300, the external device 400, and the external device 600 via broadband wireless communication (second communication). For example, the portable terminal 200 sends an emergency notification to the external device 400 and notifies the external device 300 and the external device 600 of various information such as position information, biological information, and vehicle speed via e-mail or the like.

[0083] <Processing procedure of portable terminal>

[0084] Figure 6 This is a flowchart showing the basic flow of the portable terminal 200 involved in this embodiment when a fall occurs. For example, the CPU of the control unit 201 reads the program stored in the ROM (Read Only Memory) and the storage unit 202 into the RAM (Random Access Memory) and executes it, thereby realizing the processing described below. In addition, the number following S represents the step number of each processing.

[0085] First, in S601, the control unit 201 of the portable terminal 200 establishes a communication connection with the Bluetooth unit 103 of the riding vehicle 100 via the short-range wireless device 206 when the riding vehicle 100 is started. Then, in S602, the control unit 201 determines whether information is received from the riding vehicle 100 via the short-range wireless communication connection connected in S601. If no information is received, the determination of S602 is repeated. When information is received, the process proceeds to S603, and the control unit 201 determines whether the received information is information related to a fall of the riding vehicle 100. Here, information related to a fall means information received when a fall is detected by the fall detection sensor 102 of the riding vehicle 100. If it is information related to a fall, the process proceeds to S604, and the control unit 201 performs a fall processing and ends the processing. For later use Fig. 8A On the other hand, if the information is not related to a fall, the process proceeds to S605, and the control unit 201 performs a fall determination process. Figure 8B The detailed fall determination process is described. Then, in S606, the control unit 201 determines whether a fall is detected as a result of the fall determination process in S605. If a fall is detected, the process proceeds to S604, and if a fall is not detected, the process proceeds to S607, and the control unit 201 performs other processes according to the received information and ends the process.

[0086] <What to do if a riding vehicle falls>

[0087] Figure 7 1 is a flowchart showing the processing procedure when the riding vehicle 100 involved in this embodiment falls. For example, the CPU of the control unit 101 reads the program stored in the ROM and the storage unit 104 to the RAM and executes it, thereby realizing the processing described below. In addition, the number following S represents the step number of each processing.

[0088] First, in S701, the control unit 101 of the saddle-type vehicle 100 establishes a communication connection of short-range wireless communication with the portable terminal 200 via the Bluetooth unit 103 when the saddle-type vehicle 100 is started. Then, in S702, the control unit 101 stores the information related to the vehicle speed acquired by the vehicle speed sensor 106, such as at least one of the moving speed, acceleration, and angular velocity, in the storage unit 104, and transmits it to the portable terminal 200 via short-range wireless communication. This transmission may be periodic or irregular.

[0089] Then, in S703, the control unit 101 determines whether there is a signal input from the fall detection sensor 102. If there is no signal input, the process returns to S702. On the other hand, if there is a signal input from the fall detection sensor 102, it proceeds to S704, and the control unit 101 regards that the riding vehicle 100 has been detected to have fallen, and sends the meaning of the fall and various information to the portable terminal 200 via the short-range wireless communication connection established in S701, and ends the process. The various information sent here is the action information when the riding vehicle 100 falls, such as the vehicle speed information and position information before the fall stored in the storage unit 104. Of course, other action information can also be sent. For example, information that can be detected by a sensor group provided on the riding vehicle 100, such as the fault location and other various information, can also be sent.

[0090] <Details of the portable terminal's handling when a fall occurs>

[0091] Fig. 8A This is a flowchart showing the detailed steps of the fall processing of the above-mentioned S604 of the portable terminal 200 involved in this embodiment. For example, the CPU of the control unit 201 reads the program stored in the ROM and the storage unit 202 into the RAM and executes it, thereby realizing the processing described below. In addition, the number following S represents the step number of each processing.

[0092] When it is determined in S603 that a fall has been detected, in S801, the control unit 201 outputs an alarm sound through the speaker 208, and instructs the riding vehicle 100 to sound the electric horn 105 via the short-range wireless device 206. In addition, in S802, the control unit 201 obtains the pre-set contact information in the event of a fall from the storage unit 202. And in S803, the control unit 201 displays the notification stop screen 1100 including the first operation object described later on the display operation unit 204, and instructs the riding vehicle 100 to display the second operation object for stopping the notification on the instrument panel MP via the short-range wireless device 206. Fig.11The notification stop screen 1100 is described in detail. In addition, the processing order of S801 to S803 is not intended to be particularly limited, and can be in any order. In addition, the warning instructions and display instructions of S801 and S803 issued to the saddle-type vehicle 100 can also be issued together.

[0093] Then, in S804, the first operation object or the second operation object is operated, and the control unit 201 determines whether the stop operation of the notification is accepted. In the case of accepting the stop operation, proceed to S808, and in the case of not accepting the stop operation, proceed to S805. This judgment is, for example, if the stop operation is not accepted during the period from the start of displaying the notification stop screen 1100 to the predetermined time (for example, 30 seconds, etc.), it is judged that the stop operation is not accepted, and the notification processing is transferred. In addition, as described above, the predetermined time can be changed according to the speed of the vehicle just before the fall. Moreover, the situation of operating the operation object for indicating the stop of the notification is described here, but it is not limited to this. For example, it can also be a situation that the stop operation is accepted when the rider stands up the fallen riding vehicle 100 again, and the processing of S808 is performed. For example, the situation that the signal input of the fall detection sensor 102 stops can be used as a trigger to judge that the riding vehicle 100 is re-erected. In addition, it can also be that the stop operation is performed by pressing a button set on the riding vehicle 100 for a long time. In S808, the control unit 201 instructs the saddle-type vehicle 100 via the short-distance wireless device 206 to stop the output of the alarm sound and to stop the sounding of the electric horn 105, and then ends the process.

[0094] On the other hand, in S805, the control unit 201 obtains the biological information of the rider from the wearable terminal 500. Moreover, in this notification system, the wearable terminal 500 can be an option and is not a necessary structure. That is, if the rider is not wearing the wearable terminal 500, the processing of S805 is skipped. Then, in S806, the control unit 201 obtains the current location information via GPS 205. After that, in S807, the control unit 201 notifies the pre-set contact information of the meaning of the fall, and notifies the pre-set contact information of the biological information, location information, vehicle speed information, etc. as needed, and ends the processing. Moreover, when multiple contact methods are set, the notifications are made in sequence. For example, these notifications are made to the external device 400, the external device 300, and the external device 600 as emergency contact methods in sequence.

[0095] <Details of the fall determination process of the portable terminal>

[0096] Figure 8B1 is a flowchart showing the detailed steps of the fall determination process of the portable terminal 200 in the present embodiment. For example, the CPU of the control unit 201 reads the program stored in the ROM and the storage unit 202 to the RAM and executes it, thereby realizing the process described below. In addition, the number following S represents the step number of each process.

[0097] When it is determined in S603 that no fall is detected, the control unit 201 receives information related to the vehicle speed from the riding vehicle 100 via the short-range wireless device 206 in S811. Here, for example, it is information related to the moving speed and acceleration measured by the riding vehicle 100. Then, in S812, the control unit 201 determines whether the vehicle speed (for example, the moving speed) is above a predetermined value. The predetermined value here can be set to an arbitrary speed value. For example, in order to detect a fall that occurs during driving, it can be set to 10 km per hour. If it is above the predetermined value, proceed to S813. If it is not above the predetermined value, the processing proceeds to S815. In S815, the control unit 201 determines that there is no fall and ends the processing.

[0098] In S813, the control unit 201 obtains the latest acceleration of the portable terminal 200 measured by the speed sensor 209 of the portable terminal 200 from the storage unit 202, and determines whether there is a significant difference between the acceleration obtained from the storage unit 202 and the acceleration received from the saddle-type vehicle 100 in S811. In more detail, the control unit 201 compares the two accelerations, and determines that a significant difference has occurred if the difference is above a predetermined threshold. The predetermined threshold is set to 5km to 10km per hour, for example. In the case of a difference above the threshold, it is determined that the saddle-type vehicle 100 has fallen, the rider has fallen off the vehicle, and a difference above the threshold has occurred between the accelerations of each other. That is, according to this embodiment, even in the state where the detection result of the fall detection sensor 102 is not received, regardless of whether the vehicle speed (moving speed) is above a fixed speed, it is determined that a fall has occurred when there is a significant difference between the accelerations detected by the saddle-type vehicle 100 and the portable terminal 200 held by the rider.

[0099] When it is determined that there is a significant difference between the accelerations, the process proceeds to S814, and the control unit 201 determines that it is a fall, and ends the processing. On the other hand, when it is determined that there is no significant difference between the accelerations, the process proceeds to S815, and the control unit 201 determines that there is no fall, and ends the processing. Alternatively, it may be determined that it is a fall when there is a sudden change in acceleration (assuming that the riding vehicle collides with another vehicle or an obstacle). In this case, the extent of the injury can be further predicted based on the acceleration immediately before the fall. Alternatively, even if a fall is initially determined to have occurred due to the sudden change in acceleration, when it is detected that the vehicle speed has continued for more than a fixed time, it is determined that the vehicle is continuing to travel, and the initial judgment of the fall is withdrawn.

[0100] <Processing procedure when a riding vehicle receives an alarm indication>

[0101] Fig. 9 1 is a flowchart showing the processing procedure when the saddle-type vehicle 100 according to the present embodiment receives an alarm indication. For example, the CPU of the control unit 101 reads a program stored in the ROM or the storage unit 104 into the RAM and executes the program to implement the processing described below. In addition, the number following S indicates the step number of each processing.

[0102] First, in S901, the control unit 101 receives an alarm instruction from the portable terminal 200 via the Bluetooth unit 103, and in S902, the control unit 101 causes the electric horn 105 to sound. Here, it is also possible that when the electric horn 105 is sounded, the control unit 101 controls in such a manner that the electric horn 105 is sounded only after a predetermined time has passed since the first operation object is displayed on the portable terminal 200. Thus, for example, in the case where a stop operation is accepted by means of the first operation object, the sounding of the electric 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 of a stop screen for stopping notification from the portable terminal 200 via the Bluetooth unit 103, and in S904, the notification stop screen including the second operation object is displayed on the instrument panel MP. As described above, the alarm instruction and display instruction of S901 and S903 can also be received together.

[0103] Then, in S905, the control unit 101 determines whether a stop operation is accepted via the instrument panel MP or a stop instruction is received from the portable terminal 200. If a stop operation is accepted, the process proceeds to S906. Otherwise, the determination in S905 is repeated. In S906, the control unit 101 stops the electric horn 105 from sounding and ends the process.

[0104] <Settings screen>

[0105] Fig.101 is an example of a setting screen 1000 of contact information displayed on the portable terminal 200 according to the present embodiment. The setting screen 1000 is displayed on the display operation unit 204. The setting screen 1000 described below may be displayed on the instrument panel MP in a manner that can be operated based on an instruction from the portable terminal 200.

[0106] like Fig.10 As shown, the setting screen 1000 is configured to include the following setting columns: emergency contact information 1001, contact information setting 1002 for telephone communication set by the user, and email address setting 1004 set by the user. The contact information can be input and set in each setting column. In addition, "119" is pre-set as a default setting in the emergency contact information 1001. The setting screen 1000 is configured to also include an add button 1003 and an add button 1005 corresponding to the contact information setting 1002 and the email address setting 1004, respectively. When each of the add buttons 1003 and 1005 is selected, the setting columns for the contact information and the email address can be added.

[0107] In addition, the setting screen 1000 is configured to include a confirmation button 1006 and a cancel button 1007. When the confirmation button 1006 is selected, the contact information set on the setting screen 1000 is confirmed and stored in the storage unit 202. On the other hand, when the cancel button 1007 is selected, the contact information set on the setting screen 1000 is canceled, and the setting information is not changed.

[0108] <Notification stop screen>

[0109] Fig.11 1 is an example of a notification stop screen 1100 displayed in the portable terminal 200 according to the present embodiment. The notification stop screen 1100 is displayed on the display operation unit 204. In addition, a screen similar to the notification stop screen 1100 described below is displayed on the instrument panel MP in a manner that can be operated based on an instruction from the portable terminal 200, but a detailed description is omitted.

[0110] like Fig.11As shown, the notification stop screen 1100 is configured to include the following displays: a display indicating that a notification is made to the contact information 1101 and the recipient address 1102 after a predetermined time (here, 30 seconds) has passed due to detection of the fall of the saddle-type vehicle 100, i.e., the motorcycle; and a display reminding the user to select the stop button to stop the notification when there is no problem. In addition, the notification stop screen 1100 includes a stop button 1103 and a notification button 1104. When the stop button 1103 is selected, the portable terminal 200 determines that the stop operation for the notification has been accepted, stops the alarm processing and the notification processing, and notifies the saddle-type vehicle 100 that the stop operation has been accepted. In addition, when the notification button 1104 is selected, the portable terminal 200 starts the notification processing without waiting for the predetermined time to pass. Moreover, the stop button 1103 is an example of the first operation object. In addition, the display of the second operation object displayed on the instrument panel MP of the saddle-type vehicle 100 is the same as the stop button 1103. Furthermore, a button corresponding to the notification button 1104 may be displayed on the instrument panel MP. In addition, it is desirable that the stop button 1103 continues to be displayed even after the predetermined time has passed. This is to stop the alarm by operating it when a rescuer arrives.

[0111] <Notification screen>

[0112] Fig.12 1 is an example of the notification screen 1200 displayed on the external device 300 according to the present embodiment. The notification screen 1200 is displayed on the display operation unit 301. In addition, the notification screen 1200 described below may be displayed by another external device.

[0113] The notification screen 1200 is, for example, a screen that notifies the address set by the receiving address setting 1004 that has been set in advance in the user setting of the setting screen 1000, and displays it on the external device 300. Moreover, various notification methods can be applied as a notification method to the external device 300. For example, the screen information of the notification screen 1200 can be sent to the external device 300, or only various information such as location information and biological information can be sent together with the meaning of the fall. In addition, in the external device 300, if an application associated with the present notification system is installed, the notification screen 1200 can be displayed on the application using this information, or it can be displayed on any browser screen. In addition, it is also possible to use email to only receive messages and information, and display them on the mailbox application. Or it can also be displayed on an SNS application.

[0114] The notification screen 1200 includes a message 1201 indicating that the rider of the saddle-type vehicle 100 has fallen, a map 1202 showing the location of the fall, biological information 1203 of the rider, and a voice call button 1204 to the rider. These components can be selected or rejected according to the application displayed.

[0115] The map 1202 displays a mark 1205 indicating the fall location on the map, the vehicle speed 1206 immediately before the fall, and detailed information 1207 of the fall location. The biological information 1203 displays, for example, an electrocardiogram, heart rate, blood pressure, and blood oxygen. When the voice call button 1204 is selected, the external device 300 makes a voice call to the portable terminal 200.

[0116] <Second Embodiment>

[0117] The second embodiment of the present invention is described below. Figure 8B As described, even in the state where the detection result of the fall detection sensor 102 is not received, it is determined that the person has fallen down when the accelerations acquired by the saddle-type vehicle 100 and the portable terminal 200 are significantly different at a fixed speed or above. However, in this embodiment, when there is a significant difference between the accelerations, the range of the short-range wireless communication between the saddle-type vehicle 100 and the portable terminal 200 is expanded, and information is received again from the saddle-type vehicle 100. If the detection result of the fall detection sensor 102 is not received, it is further determined whether there is no significant difference between the two accelerations. After that, the portable terminal 200 does not receive the detection result of the fall detection sensor 102 in the pre-specified maximum communication range, and it is determined that the person has fallen down when there is a significant difference between the two accelerations. That is, according to this embodiment, even when there is a significant difference between the two accelerations, it is not immediately determined that the person has fallen down, but the communication range of the short-range wireless communication is expanded to the maximum communication range to set a grace period for receiving the detection result of the fall detection sensor 102. This is because judging a fall based on the detection result of the fall detection sensor 102 is more accurate than judging based on a significant difference in acceleration. In addition, the same reference numerals and step numbers are attached to the same structures and controls as those in the first embodiment, and the description thereof is omitted.

[0118] <Details of the fall determination process of the portable terminal>

[0119] Fig.131 is a flowchart showing the detailed steps of the fall determination process of the portable terminal 200 in the present embodiment. For example, the CPU of the control unit 201 reads the program stored in the ROM and the storage unit 202 to the RAM and executes it, thereby realizing the process described below. Moreover, the number following S indicates the step number of each process. Figure 8B The same processing is assigned the same step number and the description thereof is omitted.

[0120] If it is determined in S813 that there is a significant difference in acceleration, the control unit 201 determines in S1301 whether the communication range of the short-range wireless communication between the short-range wireless device 206 and the saddle-type vehicle 100 is the maximum. If it is not the maximum, the control unit 201 proceeds to S1302, where the antenna output of the short-range wireless device 206 is increased, and the process returns to Figure 6 In S602, the information related to the vehicle speed is received again from the saddle-type vehicle 100. Alternatively, the increase in the antenna output may be increased to the maximum output at once or in stages.

[0121] On the other hand, if it is determined in S1301 that the communication range is the maximum, the process proceeds to S814, where the control unit 201 determines that the person has fallen, and ends the process. In addition, if it is determined in S813 that a significant difference has occurred and the process returns to S602, it is also conceivable that the information from the saddle-type vehicle 100 will be interrupted. In this case, it is also possible that the person has fallen after a predetermined time has passed since the initial determination that a significant difference has occurred in the acceleration.

[0122] <Modification>

[0123] In the first and second embodiments described above, whether there is a significant difference between the accelerations obtained by the riding vehicle 100 and the portable terminal 200 is used as a basis for judging a fall. The present invention is not limited to this and other judgment methods may be used. For example, a fall of the riding vehicle 100 may be detected based on whether there is a significant difference between the position information obtained by the GPS 107 of the riding vehicle 100 and the position information obtained by the GPS 205 of the portable terminal 200. Alternatively, a fall of the riding vehicle 100 may be detected when there is a significant difference in both the acceleration and the position information. It is conceivable that the significant difference in the position information is, for example, 5m to 10m.

[0124] <Summary of Implementation Methods>

[0125] The above-mentioned embodiments disclose at least the following storage medium, saddle-type vehicle, and system.

[0126] 1. A storage medium 202 storing a program for causing a computer to execute each step in a control method of a portable terminal 200, wherein the portable terminal 200 comprises: a first communication component 206 for performing short-range wireless communication with a riding vehicle 100; a second communication component 207 for communicating with an external device; and an acceleration sensor 209, wherein the control method comprises:

[0127] a receiving step (S602), receiving information from the riding vehicle via the first communication component;

[0128] a comparison step (S813), in which, when the moving speed of the riding vehicle included in the information of the riding vehicle is greater than a predetermined value, the acceleration of the riding vehicle included in the information from the riding vehicle is compared with the acceleration acquired by the acceleration sensor of the portable terminal to determine whether a significant difference occurs; and

[0129] The fall determination step (S814) is to determine that the riding vehicle has fallen, based on the determination that a significant difference has occurred in the comparison step.

[0130] According to this embodiment, the information related to the vehicle speed received from the saddle-type vehicle 100 is compared with the information related to the acceleration acquired by the portable terminal 200, so that the fall of the saddle-type vehicle 100 can be detected in the portable terminal 200. In addition, since the fall can be determined by the portable terminal 200, the communication function of the portable terminal 200 such as a smartphone can be used for notification.

[0131] 2. In the above embodiment, the riding vehicle 100 is provided with a fall detection component 102 and a Bluetooth unit 103, and the fall detection component 102 detects the fall of the riding vehicle.

[0132] In the fall determination step, when the information from the riding vehicle includes the output of the fall detection component, it is determined that the riding vehicle has fallen regardless of the judgment result in the comparison step (S603).

[0133] According to this embodiment, a fall can be determined based on the output of the fall detection sensor 102 provided in the riding vehicle 100, so a fall determination with higher accuracy can be performed. In addition, only the Bluetooth unit 103 is provided in the riding vehicle 100, and the 4G / 5G communication subject can use the portable terminal 200 such as the smartphone of the rider. Therefore, even in the case of notification, the smartphone can be integrated from the viewpoint of communication fee, etc.

[0134] 3. In the above embodiment, in the fall determination step, according to the determination that a significant difference occurs in the comparison step,

[0135] When the communication range of the first communication module with the riding vehicle is not the maximum communication range, the antenna output of the first communication module is increased (S1301, S1302),

[0136] When the communication range of the first communication module with the saddle-type vehicle is the maximum communication range, it is determined that the saddle-type vehicle has fallen down (S1301, S814).

[0137] According to this embodiment, when the saddle-type vehicle 100 falls, even if the saddle-type vehicle 100 and the portable terminal 200 owned by the rider are physically separated, communication can be ensured to a certain extent to receive the output of the fall detection sensor 102.

[0138] 4. In the above embodiment, the portable terminal further comprises a location information acquisition component 205, and the location information acquisition component 205 acquires the location information of the portable terminal.

[0139] In the comparison step, instead of or in addition to determining the significant difference related to the acceleration,

[0140] The position information 107 of the riding vehicle included in the information from the riding vehicle is compared with the position information acquired by the position information acquisition component of the portable terminal to determine whether a significant difference occurs (S813).

[0141] According to this embodiment, instead of determining the significant difference in acceleration or in addition to determining the significant difference in acceleration, it is possible to determine whether there is a significant difference in position information between the GPS 107 of the saddle-type vehicle 100 and the GPS 205 of the portable terminal 200 to perform a fall determination.

[0142] 5. In the above embodiment, it also includes a notification step (S604, S807), in which the second communication component 207 notifies a predetermined receiving address based on the determination that the riding vehicle has fallen.

[0143] According to this embodiment, when the fall of the saddle-type vehicle 100 is detected by the portable terminal 200, notification can be made using the communication function of the portable terminal 200. Thus, the smartphone can be integrated from the viewpoint of communication charges and the like.

[0144] 6. In the above embodiment, the method further includes the following step (S803): displaying a first operation object on a display unit of the portable terminal, the first operation object being used to receive an operation of stopping the notification in the notification step.

[0145] According to this embodiment, since the operation target for stopping the notification is displayed on the operation display unit of the portable terminal 200, the notification can be canceled in the case of a fall that does not require notification.

[0146] 7. In the above embodiment, the following steps (S803, S904) are also included: notifying the riding vehicle of a display instruction via the first communication component, so that a second operation object is displayed on the display unit of the riding vehicle, and the second operation object is used to accept an operation to stop the notification of the notification step.

[0147] According to this embodiment, the operation object for stopping the notification is displayed on the instrument panel MP of the riding vehicle 100, so the notification can be canceled when a fall occurs and the notification is not required. For example, even if the portable terminal 200 is thrown away due to a fall or a malfunction occurs, the notification can be stopped if the rider himself is fine.

[0148] 8. In the above embodiment, the period during which the first operation object is displayed is changed according to the vehicle speed immediately before the ride-type vehicle falls.

[0149] According to this embodiment, for example, the slower the vehicle speed, the less necessary the notification is, so the time can be extended. On the other hand, the faster the vehicle speed, the more necessary the notification is, so the time can be shortened.

[0150] 9. In the above embodiment, the period during which the second operation target is displayed is set to be longer than the period during which the first operation target is displayed.

[0151] According to this embodiment, even if the motorcycle and the rider are separated from each other due to a fall, for example, the rider and the smartphone are still together in most cases, and when considering moving to the motorcycle, a longer time is set on the motorcycle side, thereby giving the rider a grace period to stop the operation.

[0152] 10. In the above embodiment, in the notification step, in addition to notifying that the riding vehicle has fallen, the position information acquired by the position information acquisition component 205 provided in the portable terminal is also notified (S807, S808).
