[0013] Hereinafter, a device use control system, an electric bicycle, a device use control method, and a program according to embodiments will be described.

[0014] (Embodiment) <Configuration> [Electric bicycle] First, an electric bicycle 2 using the equipment use control system 1 will be described. Fig. 1 is a block diagram illustrating an electric bicycle 2 equipped with the equipment use control system 1 according to an embodiment. Fig. 2 is a side view illustrating the electric bicycle 2 according to an embodiment.

[0015] 1 and 2, an electric bicycle 2 is a vehicle that can travel on a road surface using electrical power. In the embodiment, the electric bicycle 2 is used as an example of a vehicle, but the vehicle is not limited to the electric bicycle 2. A vehicle is a mobile object that has a body 10 that can travel on a road surface by rotating wheels, such as an automobile, a motorcycle, a human-powered vehicle, or a bicycle.

[0016] The electric bicycle 2 of the embodiment is an electrically assisted bicycle that supplements the user's pedaling force with the auxiliary driving force of the electric motor 45. That is, in the embodiment, the electric bicycle 2 is equipped with a usage equipment control system 1 and an electric motor 45 that applies auxiliary driving force to assist the running of the vehicle body 10. Note that the electric bicycle 2 may be configured such that the human-powered driving that powers the wheels using pedaling force and the auxiliary driving force that powers the wheels using the electric motor 45 are separate, or the bicycle may be capable of running (self-propelled) using only the electric motor 45.

[0017] For example, the electric bicycle 2 has an assist mode, a push-walking mode, and a self-propelled mode. The assist mode is a mode that assists the forward movement of the electric bicycle 2 based on the user's pedaling force on the pedals 16. The push-walking mode is a mode that assists the forward movement of the electric bicycle 2 based on the force applied by the user to push the body 10 forward when the user walks while pushing the electric bicycle 2. The self-propelled mode is a mode that assists the forward movement of the electric bicycle 2 when the user walks while supporting the electric bicycle 2.

[0018] The electric bicycle 2 is composed of a body 10 on which an equipment control system 1 is mounted.

[0019] The vehicle body 10 has a frame 11, a front wheel 12, a rear wheel 13, a saddle 14, handlebars 15, pedals 16, a crank 17, a chain 19, a transmission 51, a suspension 52, a sensor, a control device 40, a motor unit 44, a notification module 50, an operating unit 61, a manual switch 62, and a battery 63.

[0020] The frame 11 is the framework of the electric bicycle 2. The frame 11 is made of metal such as aluminum alloy, iron, chrome molybdenum steel, steel, or titanium. The frame 11 may also be made of carbon, synthetic resin, or the like.

[0021] The frame 11 has a front frame 11a and a rear frame 11b.

[0022] The front frame 11a forms the front portion of the frame 11. The front frame 11a has a head tube 11a1, a down tube 11a2, and a seat tube 11a3. The frame 11 may have a suspension.

[0023] The head tube 11a1 is connected to the front end of the front frame 11a. A front fork 11a4 and a handlebar 15 are attached to the head tube 11a1 so as to be rotatable about an axis along the longitudinal direction of the head tube 11a1. A front wheel 12 is rotatably attached to the front fork 11a4. By turning the handlebar 15 left and right, the orientation of the front wheel 12 supported by the front fork 11a4 can be rotated left and right. A headlight is attached to the front fork 11a4. A suspension 52 is attached to the front fork 11a4. In this embodiment, the suspension 52 is configured to have an adjustable damping force by being controlled by a usage equipment control system 1, which will be described later.

[0024] The down tube 11a2 connects the head tube 11a1 and the seat tube 11a3. The down tube 11a2 is provided with a battery 63, a motor unit 44, and a control device 40.

[0025] The seat tube 11a3 holds the saddle 14. The saddle 14 is attached to the seat tube 11a3 so as to be movable along the longitudinal direction of the seat tube 11a3. The lower end of the seat tube 11a3 is connected to the rear end of the down tube 11a2. The seat tube 11a3 is located between the front wheel 12 and the rear wheel 13 in the front-to-rear direction. A battery 63 is detachably attached to the seat tube 11a3.

[0026] The rear frame 11b is disposed rearward of the front frame 11a and constitutes the rear portion of the frame 11. The rear wheel 13, a rear sprocket 71 linked to the axle of the rear wheel 13, and a rear seat 80 are attached to the rear frame 11b. In this embodiment, the rear seat 80 functions as a carrier for carrying a child. Of course, the rear seat 80 may function as a carrier for carrying luggage instead of a child. A chain 19 is stretched between the rear sprocket 71 and the front sprocket 72. As a result, the rotational force of the front sprocket 72, which is rotated when the pedal 16 is depressed, is transmitted to the rear wheel 13 via the chain 19 and the rear sprocket 71. In this embodiment, the pedal 16, the front sprocket 72, the rear sprocket 71, and the chain 19 form a rear wheel drive mechanism that relies on human power.

[0027] The front wheel 12 has a tire 12a on which the vehicle body 10 travels. The front wheel 12 is the front wheel of two wheels aligned in the front-to-rear direction. The front wheel 12 is supported by a front fork 11a4 so that it can rotate around an axis that extends in the left-to-right direction. Note that the front wheel 12 may receive power from a motor unit 44, and for example, a motor may be provided that applies driving force to rotate the front wheel 12.

[0028] The rear wheel 13 has a tire 13a on which the vehicle body 10 travels. The rear wheel 13 is the rear wheel of two wheels aligned in the front-to-rear direction. The rear wheel 13 is supported by a rear fork so that it can rotate around an axis along the left-to-right direction. The rear wheel 13 may receive power from a motor unit 44, and for example, may be provided with a motor that applies driving force to rotate the rear wheel 13. The rear wheel 13 has a rear sprocket 71. The rear sprocket 71 is connected to a front sprocket 72 via a chain 19. In this embodiment, power output from the motor unit 44 is transmitted to the rear wheel 13.

[0029] The saddle 14 is a portion on which a user sits and is attached so as to be movable relative to the seat tube 11a3.

[0030] The handlebars 15 change the steering angle of the electric bicycle 2, for example, when the user steers the electric bicycle 2. A pair of grips and a pair of brake levers 81 are provided on both ends of the handlebars 15. The pair of grips are held by the user's hands when riding in an appropriate posture. The pair of grips are also held by the hands when pushing or supporting the electric bicycle 2, and receive a forward pushing force. One brake lever 81 applies a mechanical braking force to the front wheel 12 by actuating a front brake device (not shown). The other brake lever 81 applies a mechanical braking force to the rear wheel 13 by actuating a rear brake device (not shown).

[0031] At least one of the pair of grips may be provided with a grip sensor that detects the gripping force or pushing force. A steering angle sensor that measures the steering angle of the handlebars 15 may be provided on a rotation shaft provided at the center of the handlebars 15, and this steering angle sensor may detect the steering angle of the handlebars 15. A brake sensor may be provided on the brake lever 81, and this brake sensor may detect the operation of the brake lever 81.

[0032] For example, when the user rides the electric bicycle 2, the pedal 16 receives the user's pedaling force. The pedal 16 is attached to one of the longitudinal ends of each crank arm 17a, on the opposite side from the crank shaft 17b. The pedal 16 is rotatably attached to the crank arm 17a. The rotation axis of the pedal 16 is approximately parallel to the rotation axis of the crank shaft 17b of the crank 17.

[0033] The crank 17 has a crankshaft 17b, a pair of crank arms 17a, and a front sprocket 72. One crank arm 17a is provided on each side of the front frame 11a and is fixed to both ends of the crankshaft 17b extending in the left-right direction. One end of the crank arm 17a is rotatably fixed to the crankshaft 17b, and the pedal 16 is rotatably fixed to the other end of the crank arm 17a. When a pedal force is applied to the pedal 16, the crank arm 17a rotates about the crankshaft 17b, and the human driving force generated by this rotation is transmitted to the rear wheel 13 via the front sprocket 72 and the chain 19. When operating in the assist mode, the human driving force based on the pedal force and the auxiliary driving force generated by the electric motor 45 added to the human driving force are transmitted to the rear wheel 13. The front sprocket 72 is attached to the crankshaft 17b of the crank arm 17a. When a user steps on the pedal 16, the front sprocket 72 rotates via the crank arm 17a and the crank shaft 17b. The rotation of the front sprocket 72 rotates the rear sprocket 71 via the chain 19, and also rotates the rear wheel 13.

[0034] The chain 19 transmits the rotational force of the front sprocket 72, which is rotated when the pedal 16 is depressed, and the auxiliary driving force output from the motor unit 44 to the rear sprocket 71. The chain 19 is a power transmission body such as a belt, a shaft, a wire, or a gear.

[0035] The transmission 51 is configured with a well-known transmission mechanism such as a planetary gear or multi-speed gear having a plurality of driving force transmission paths with different gear ratios. The transmission 51 can change the driving force transmission path, for example, to a low gear, a medium gear, or a high gear, by switching the driving force transmission path. The transmission 51 may be configured to manually switch the driving force transmission path, or may be configured to electrically switch the driving force transmission path. In this embodiment, the transmission 51 is configured to electrically switch the gear ratio by being controlled by a control unit 43 of the device control system 1 described later.

[0036] The sensors detect information related to the traveling of the body 10. In this embodiment, multiple sensors are mounted on the electric bicycle 2. The multiple sensors mounted on the electric bicycle 2 include a first speed sensor 31, a second speed sensor 32, a torque sensor 33, and a gyro sensor 34.

[0037] The first speed sensor 31 and the second speed sensor 32 each detect the speed at which the electric bicycle 2 is traveling (the speed of the electric bicycle 2) when the assist mode, the pushing mode, or the self-propelled mode is in operation, and output information indicating the detected speed of the electric bicycle 2 to the control device 40. This information corresponds to speed information relating to the traveling speed of the body 10 (the speed of the electric bicycle 2).

[0038] The first speed sensor 31 is, for example, a wheel sensor that detects the speed of the electric bicycle 2 from the rotation of the front wheel 12 or the rear wheel 13. The second speed sensor 32 is, for example, a speed sensor that detects the speed of the electric bicycle 2 using a positioning system such as a GPS (Global Positioning System).

[0039] The first speed sensor 31 is provided, for example, at the lower end of the front fork 11a4, in a position where it is easy to measure the speed. When provided on the front fork 11a4, it can suitably detect the rotation speed of the front wheel 12. When the first speed sensor 31 is attached to the rear of the frame 11, it can suitably detect the rotation speed of the rear wheel 13. The detection target of the first speed sensor 31 can be at least one of the front wheel 12 and the rear wheel 13.

[0040] The torque sensor 33 detects a manual driving force based on a pedaling force on the pedal 16. That is, the torque sensor 33 detects a manual driving force generated by the rotation of the crankshaft 17b based on the pedaling force on the pedal 16. The torque sensor 33 is a magnetostrictive sensor having a coil and a magnetostriction generating portion. For example, when a pedaling force is applied to the pedal 16 to generate a manual driving force, distortion occurs in the magnetostriction generating portion. The magnetostriction generating portion has portions where the magnetic permeability increases and portions where it decreases. The torque sensor 33 detects the manual driving force by detecting the inductance difference of this coil. The torque sensor 33 outputs information indicating the detected manual driving force to the control device 40. The configuration of the torque sensor 33 is not particularly limited, and any configuration may be used as long as it can detect the manual driving force on the pedal 16. The torque sensor 33 is disposed, for example, near the crankshaft 17b.

[0041] The gyro sensor 34 is a six-axis sensor that detects the tilt speed (angular velocity) of the body 10 of the electric bicycle 2. The gyro sensor 34 detects acceleration in each of three axes perpendicular to the center of the electric bicycle 2 and angular velocity around the three axes. The gyro sensor 34 detects acceleration in each of the three axes and angular velocities (roll, yaw, and pitch) around the three axes. The gyro sensor 34 outputs information indicating the detected angular velocity and acceleration to the control device 40. The gyro sensor 34 is attached to, for example, the down tube 11a2. The three orthogonal axes may be represented, for example, by the X-axis direction, the Y-axis direction, and the Z-axis direction, with the front-to-back direction defined as the X-axis direction, the Y-axis direction defined as the left-to-right direction, and the Z-axis direction defined as the up-down direction.

[0042] In the embodiment, the first speed sensor 31, the second speed sensor 32, the torque sensor 33, and the gyro sensor 34 are given as examples of sensors that the electric bicycle 2 has, but the present invention is not limited to these.

[0043] For example, the electric bicycle 2 may further include an inclination sensor that detects the inclination of the electric bicycle 2 with respect to a horizontal plane. The inclination sensor may output information indicating the detected inclination angle to the control device 40.

[0044] Furthermore, for example, the electric bicycle 2 may further include a battery state detection sensor that detects the state of the battery 63, such as the charge rate, discharge performance, or remaining capacity of the battery 63. The battery state detection sensor may output information indicating the detected state of the battery 63 to the control device 40.

[0045] Furthermore, for example, the electric bicycle 2 may have a vibration sensor that detects vibrations of the body 10. The vibration sensor may output to the control device 40 information indicating the magnitude (frequency) of the vibrations.

[0046] Furthermore, for example, the electric bicycle 2 may have an acceleration sensor that detects the acceleration of the traveling body 10. The acceleration sensor may output information indicating the acceleration of the body 10 to the control device 40.

[0047] Furthermore, for example, the electric bicycle 2 may have a sound sensor that detects sounds generated from the body 10, the motor unit 44, etc. The sounds are, for example, sounds emitted from the front sprocket 72 and rear sprocket 71, the chain 19, the brake device, etc. If an abnormality occurs in the front sprocket 72 and rear sprocket 71, the chain 19, the brake device, the tires 12a, 13a, the transmission 51, etc., an abnormal sound that is different from a normal state will be generated. The sound sensor may output information indicating the sound quality, volume, etc. to the control device 40.

[0048] The electric bicycle 2 may also have a motor rotation sensor that detects the number of rotations per unit time of the electric motor 45. The motor rotation sensor may be a Hall IC sensor or the like, and may output information indicating the number of rotations per unit time of the electric motor 45 to the control device 40. The speed of the electric bicycle 2, the driving force of the electric motor 45, etc. may be calculated based on the information indicating the number of rotations per unit time of the electric motor 45.

[0049] The motor unit 44 outputs an auxiliary driving force, thereby adding the auxiliary driving force to the pedaling force, which is the human driving force, and transmits it to the rear wheel 13 via the chain 19.

[0050] The motor unit 44 has an electric motor 45. The motor unit 44 is a unit in which the electric motor 45 and the control device 40 are housed in a housing made of resin or metal. The torque sensor 33 and the like are provided inside the housing. The motor unit 44 is attached to the vehicle body 10.

[0051] The electric motor 45 applies an auxiliary driving force to assist the traveling of the vehicle body 10. The electric motor 45 receives power from the battery 63 and is driven under the control of the control device 40. The electric motor 45 transmits rotational torque as the auxiliary driving force to the rear sprocket 71 via the chain 19, thereby rotating the rear wheel 13. The rotational torque is the auxiliary driving force, which is a driving force by the electric motor 45 to be added to the human-powered driving force, and the auxiliary driving force, which is an auxiliary force imparted to the force of pushing or walking while supporting the electric bicycle 2. The electric motor 45 adds the auxiliary driving force to the human-powered driving force based on the force applied to the pedals 16 while operating in the assist mode. Furthermore, the electric motor 45 adds the auxiliary driving force to the force of pushing the electric bicycle 2 while operating in the push-walking mode. Furthermore, the electric motor 45 adds the auxiliary driving force to the force of pushing the electric bicycle 2 while operating in the self-propelled mode, allowing the electric bicycle 2 to self-propel while being supported by the user.

[0052] The control device 40 is realized by, for example, a microcomputer (microcontroller) or the like, and is composed of a non-volatile memory in which a program is stored, a volatile memory (storage unit) which is a temporary storage area for executing the program, an input / output port, a processor for executing the program, etc. The control device 40 may also be realized by a dedicated electronic circuit.

[0053] The electric motor 45, the first speed sensor 31, the second speed sensor 32, the torque sensor 33, the gyro sensor 34, the notification module 50, the transmission 51, the suspension 52, the operation unit 61, the manual switch 62, the battery 63, and the headlights are electrically connected to the control device 40. Operation signals from the operation unit 61 and the manual switch 62, as well as information indicating the detection results from each sensor, are input to the control device 40.

[0054] The control device 40 drives the electric motor 45 according to the operation mode of the electric bicycle 2. Specifically, the control device 40 switches between assist mode, pushing mode, and self-propelled mode, and executes each mode. Assist mode is executed when the user is riding the electric bicycle 2 after the manual switch 62 is pressed to turn on the power. When executing assist mode, the control device 40 determines the magnitude of the auxiliary driving force generated by the electric motor 45 based on factors such as the force applied to the pedals 16 and the speed of the electric bicycle 2. Pushing mode is executed when the user is not riding the electric bicycle 2, the manual switch 62 is pressed to turn on the power, and the user is pushing the body 10 of the electric bicycle 2. Self-propelled mode, like the pushing mode, is executed when the user is not riding the electric bicycle 2 and is walking while supporting the body 10 of the electric bicycle 2. In self-propelled mode, the user is not exerting any force to push the body 10 forward. Furthermore, when the pushing mode is executed, the control device 40 determines the magnitude of the auxiliary driving force to be generated by the electric motor 45 based on the pushing force applied to the electric bicycle 2 and the speed of the electric bicycle 2. Furthermore, when the self-propelling mode is executed, the control device 40 determines the magnitude of the predetermined auxiliary driving force to be generated by the electric motor 45.

[0055] The control device 40 also supplies the electric power from the battery 63 to the electric motor 45, the headlights, and the like.

[0056] In the embodiment, the control device 40 is housed inside the housing of the motor unit 44, but this is not limiting. The control device 40 may be provided separately from the motor unit 44.

[0057] The notification module 50 is a notification module capable of wireless or wired communication with the external device 9. Here, the external device 9 is a device that exists outside the usage equipment control system 1. The external device 9 may include, for example, an information terminal or a server device (see FIG. 3) described below. The information terminal is a device owned by the user riding the electric bicycle 2, such as a smartphone, tablet terminal, or personal computer. For example, if the information terminal is a smartphone, the user can check various information sent from the notification module 50 via the smartphone.

[0058] The operation unit 61 is provided, for example, near one of the pair of brake levers 81. The operation unit 61 is a terminal device such as a cycle computer that is equipped with a light switch (not shown) for turning on the headlights, etc. The operation unit 61 has buttons and the like for accepting operations by the user. The buttons are, for example, a touch panel display or mechanical buttons.

[0059] The operation unit 61 has an alarm module 61a for providing notifications to those around the vehicle body 10. For example, the alarm module 61a is a display unit that displays various types of information. The display unit is, for example, a liquid crystal display or an organic EL display. The alarm module 61a may also be an acoustic unit such as an electronic bell that notifies those around the vehicle body 10 of various types of information by sound. The acoustic unit may be a speaker that outputs sound. The alarm module 61a may also be a vibration unit that notifies the user of various types of information by vibration. The vibration unit may be a vibration generator having a vibration generating function (vibration function) that transmits vibration to the user by vibrating the operation unit 61. The vibration generator may be a vibration motor that generates vibrations, or the like. The alarm module 61a may also be a light source unit that notifies the user of various types of information by light. The light source unit may be an LED module that emits light of a single color or multiple colors, or the like.

[0060] Thus, the display unit, the sound unit, the vibration unit, and the light source unit are an example of the notification module 61a. The operation unit 61 has at least one of the display unit, the sound unit, the vibration unit, and the light source unit as the notification module 61a.

[0061] The manual switch 62 is a mechanical switch that accepts a push-walking operation or a self-propelled operation to execute the push-walking mode or the self-propelled mode. While the manual switch 62 is pressed by the user, the operation unit 61 continues to output a mode-on signal to the control device 40 to execute the push-walking mode or the self-propelled mode. On the other hand, while the manual switch 62 is not pressed, the operation unit 61 does not output a mode-on signal to the control device 40.

[0062] Note that when the manual switch 62 is pressed once, the pushed walking mode or the self-propelled mode may be executed without continuing to press the manual switch 62. When the manual switch 62 is pressed again while the pushed walking mode or the self-propelled mode is being executed, the pushed walking mode or the self-propelled mode may be stopped.

[0063] The battery 63 is a storage battery that stores power for driving the electric motor 45. The battery 63 is, for example, a secondary battery, but may also be a capacitor or the like. The battery 63 is electrically connected to the electric motor 45. Specifically, the battery 63 supplies power to the electric motor 45.

[0064] [Device control system used] Next, we will explain the usage device control system 1. The usage device control system 1 includes an acquisition unit 41, a detection unit 42, and a control unit 43. In the embodiment, the acquisition unit 41, the detection unit 42, and the control unit 43 are all realized as functions of the control device 40.

[0065] The acquisition unit 41 acquires speed information related to the traveling speed of the vehicle body 10. The speed information may include, for example, not only the traveling speed of the vehicle body 10 but also the acceleration of the vehicle body 10 while traveling. Furthermore, the speed information may include, for example, information related to the speed of a part of the vehicle body 10 (for example, a wheel) rather than the entire vehicle body 10. In the embodiment, the acquisition unit 41 acquires, as the speed information, a first detection result by a first speed sensor 31 that detects the speed of the wheels (front wheels 12 or rear wheels 13) of the vehicle body 10 and a second detection result by a second speed sensor 32 that detects the speed of the vehicle body 10 using a positioning system (here, GPS).

[0066] The detection unit 42 detects the air pressures of the tires 12a, 13a of the vehicle body 10 based on the speed information acquired by the acquisition unit 41. Here, the detection unit 42 may detect the air pressures of the tires 12a of the front wheels 12 and the tires 13a of the rear wheels 13 individually, or may detect the air pressure of only one of them. Furthermore, the detection unit 42 may use the detection result as a representative value of the air pressures of the tires 12a, 13a without distinguishing between the tires 12a of the front wheels 12 and the tires 13a of the rear wheels 13. Furthermore, "detecting the air pressures of the tires 12a, 13a" as used herein may include estimating the air pressures of the tires 12a, 13a.

[0067] In this embodiment, the detection unit 42 detects the air pressures of the tires 12a, 13a based on a comparison between a first detection result from the first speed sensor 31 and a second detection result from the second speed sensor 32. For example, the air pressures of the tires 12a, 13a when the difference between the speed of the vehicle body 10 based on the rotational speed of the wheels detected by the first speed sensor 31 and the speed of the vehicle body 10 detected by the second speed sensor 32 is zero is assumed to be the reference air pressure. In this case, if the speed of the vehicle body 10 detected by the first speed sensor 31 is higher than the speed of the vehicle body 10 detected by the second speed sensor 32, the detection unit 42 detects that the air pressures of the tires 12a, 13a are lower than the reference air pressure in accordance with the difference. On the other hand, if the speed of the vehicle body 10 detected by the first speed sensor 31 is lower than the speed of the vehicle body 10 detected by the second speed sensor 32, the detection unit 42 detects that the air pressure of the tires 12a, 13a is higher than the reference air pressure according to the difference.

[0068] The control unit 43 controls the equipment 5 used on the vehicle body 10 in accordance with the state of the tires 12a, 13a based on the air pressure of the tires 12a, 13a detected by the detection unit 42. The term "equipment" as used here may include not only equipment mounted on the vehicle body 10, but also equipment provided separately from the vehicle body 10 but used on the vehicle body 10. Examples of the equipment 5 mounted on the vehicle body 10 may include the electric motor 45, the notification module 50, the transmission 51, the suspension 52, or the alarm module 61a. Examples of the equipment 5 provided separately from the vehicle body 10 may include the air filling machine 3 (see FIG. 3).

[0069] Below are listed examples of control of the usage device 5 by the control unit 43. The control unit 43 does not need to control the usage device 5 according to all of the examples listed below, but only needs to control the usage device 5 according to at least one of the examples listed below.

[0070] In the first example, the equipment 5 is an electric motor 45 that applies auxiliary driving force to assist the vehicle body 10 in traveling. The control unit 43 controls the electric motor 45 to adjust the auxiliary driving force according to the air pressure of the tires 12a, 13a. That is, when the air pressure of the tires 12a, 13a decreases, the contact area between the tires 12a, 13a and the ground increases. Therefore, when the same auxiliary driving force is applied, the traveling speed of the vehicle body 10 is likely to be slower than when the air pressure of the tires 12a, 13a does not decrease. Therefore, in order to achieve the same traveling speed of the vehicle body 10 as when the air pressure of the tires 12a, 13a does not decrease, the user must apply more pedal force to the pedal 16, which tends to impose a burden on the user.

[0071] Therefore, in the first example, the control unit 43 controls the electric motor 45 to increase the auxiliary driving force as the air pressure of the tires 12a, 13a decreases, for example. As a result, even if the air pressure of the tires 12a, 13a decreases, by applying the same pedal force to the pedal 16 as when the air pressure of the tires 12a, 13a does not decrease, the vehicle body 10 can travel at the same speed as when the air pressure of the tires 12a, 13a does not decrease. As a result, the load on the user can be reduced.

[0072] In the first example, the control unit 43 may further refer to the types of the tires 12a, 13a and the circumferential lengths of the tires 12a, 13a based on the air pressures of the tires 12a, 13a to control the electric motor 45. The types of the tires 12a, 13a referred to here include, for example, the tread patterns of the tires 12a, 13a or the outer diameters of the tires 12a, 13a.

[0073] That is, when the air pressure of the tires 12a, 13a increases or decreases, the circumferential lengths of the tires 12a, 13a also increase or decrease. For example, when the air pressure of the tires 12a, 13a decreases, the circumferential lengths of the tires 12a, 13a decrease. The traveling speed of the vehicle body 10 is calculated based on the rotational speed of the wheels and the circumferential lengths of the tires 12a, 13a. Therefore, a change in the circumferential lengths of the tires 12a, 13a may reduce the accuracy of calculating the traveling speed of the vehicle body 10.

[0074] Therefore, the control unit 43 estimates the circumferential length of the tires 12a, 13a based on the type of the tires 12a, 13a and changes in the air pressure of the tires 12a, 13a, and calculates the traveling speed of the vehicle body 10 by referring to the estimated circumferential length of the tires 12a, 13a. This makes it easier to understand the effect that an increase or decrease in the air pressure of the tires 12a, 13a has on the traveling speed of the vehicle body 10, and makes it easier to adjust the auxiliary drive force more appropriately according to the air pressure of the tires 12a, 13a.

[0075] In the second example, the equipment 5 in use is a transmission 51. The control unit 43 controls the transmission 51 to adjust the gear ratio according to the air pressure of the tires 12a, 13a. For example, when the air pressure of the tires 12a, 13a decreases, the control unit 43 controls the transmission 51 to decrease the gear ratio as the tires 12a, 13a descend. This allows the user to easily feel the same riding comfort as when the air pressure of the tires 12a, 13a does not decrease, even when the air pressure of the tires 12a, 13a decreases.

[0076] In the third example, the equipment 5 in use is a suspension 52. The control unit 43 controls the suspension 52 to adjust the damping force according to the air pressure of the tires 12a and 13a. For example, when the air pressure of the tires 12a and 13a decreases, the control unit 43 controls the transmission 51 to reduce the damping force as the air pressure of the tires 12a and 13a decreases. This allows the user to easily feel the same riding comfort as when the air pressure of the tires 12a and 13a does not decrease, even when the air pressure of the tires 12a and 13a decreases.

[0077] In the fourth example, the equipment 5 to be used is an air filling machine 3. The control unit 43 controls the air filling machine 3 so that the amount of air to be replenished into the tires 12a, 13a is adjusted according to the air pressures of the tires 12a, 13a. Here, FIG. 3 is a schematic diagram illustrating the air filling machine 3 according to the embodiment. The air filling machine 3 is installed, for example, in a public facility or a commercial facility. The air filling machine 3 has a nozzle that can be inserted into the valve of the tire 12a, 13a, and supplies air to the tire 12a, 13a via the nozzle and the valve by receiving a predetermined operation (for example, pressing a switch provided on the air filling machine 3) with the nozzle inserted into the valve.

[0078] The control unit 43 indirectly controls the air filling machine 3, for example, by performing wired or wireless communication with the air filling machine 3. Then, for example, if the air pressure of the tires 12a, 13a is low, the control unit 43 controls the air filling machine 3 to replenish air into the tires 12a, 13a until the air pressure of the tires 12a, 13a reaches an appropriate air pressure. This allows the user to automatically adjust the air pressure of the tires 12a, 13a to an appropriate air pressure without having to manually operate the air filling machine 3 to increase or decrease the amount of air replenished into the tires 12a, 13a, thereby improving convenience.

[0079] In the fifth example, the equipment 5 in use is a notification module 50 for communicating with an external device 9. The control unit 43 controls the notification module 50 to transmit status information relating to the status of the tires 12a, 13a to the external device 9. Here, the status information may be information relating to the status of each of the tires 12a of the front wheels 12 and the tires 13a of the rear wheels 13, or may be information relating to the status of only one of them. Furthermore, the status information may be information that does not distinguish between the tires 12a of the front wheels 12 and the tires 13a of the rear wheels 13.

[0080] The status information may include, for example, information indicating a change in the air pressure of the tires 12a, 13a, or information indicating that the air pressure of the tires 12a, 13a is not appropriate, etc. Furthermore, if the air pressure of the tires 12a, 13a has dropped, the status information may include, for example, information indicating that loading people or luggage on a carrier such as the rear seat 80 is prohibited, or information indicating that it is recommended to walk while pushing the vehicle body 10, etc.

[0081] The control unit 43 transmits the status information to an information terminal serving as the external device 9, for example, by controlling the notification module 50. As a result, the user can check the status information via the information terminal and understand the status of the tires 12a, 13a, such as whether the air pressure of the tires 12a, 13a has dropped.

[0082] In the sixth example, the device 5 in use is a notification module 61a for issuing notifications to those around the vehicle body 10. The control unit 43 controls the notification module 61a to notify those around the vehicle body 10 of status information related to the status of the tires 12a, 13a. This allows a user who is around the vehicle body 10 to get on the vehicle body 10 to know the status of the tires 12a, 13a, such as whether the air pressure of the tires 12a, 13a has dropped.

[0083] [Vehicle sharing system] Next, a description will be given of the vehicle sharing system 100. Fig. 4 is a schematic diagram illustrating the vehicle sharing system 100 according to the embodiment.

[0084] As shown in Figure 4, vehicle sharing system 100 is a system in which a servicer that rents out vehicles rents out vehicles to users who wish to use the vehicles. Vehicle sharing system 100 manages the vehicle's condition, specifications, model, product number, etc. Furthermore, when renting out a vehicle to a user, vehicle sharing system 100 manages the start time of use, end time of use, start location of use, user identification information, etc. In this embodiment, vehicle sharing system 100 rents out electric bicycles 2, etc.

[0085] The vehicle sharing system 100 includes a server device as an external device 9. The server device is managed by a servicer that owns multiple electric bicycles 2, and is a device that exists outside the usage equipment control system 1. The server device manages the status of the tires 12a, 13a of the body 10 for each electric bicycle 2 by collecting status information sent from the usage equipment control system 1. The server device outputs the status of the tires 12a, 13a of the body 10 for each electric bicycle 2 to a notification device such as a monitor for the servicer. This allows the servicer to know when to perform maintenance such as repairs or adjustments on the electric bicycle 2, depending on the status of the tires 12a, 13a of the body 10 of the electric bicycle 2.

[0086] <Operation> An example of the operation of the appliance use control system 1 according to the embodiment will be described below with reference to Figs. 5 and 6. Fig. 5 is a flowchart illustrating an example of the basic operation of the appliance use control system 1 according to the embodiment. Fig. 6 is a flowchart illustrating an example of control of the electric motor 45 in the appliance use control system 1 according to the embodiment. This control example corresponds to the first example of the control unit 43 described above.

[0087] [Basic operation example] In an example of basic operation, the acquisition unit 41 of the equipment use control system 1 acquires speed information related to the traveling speed of the vehicle body 10 (S11). Here, the acquisition unit 41 periodically acquires the detection results of the first speed sensor 31 and the second speed sensor 32.

[0088] Next, the detection unit 42 of the usage equipment control system 1 detects the air pressures of the tires 12a, 13a based on the speed information acquired by the acquisition unit 41 (S12). Here, the detection unit 42 detects the air pressures of the tires 12a, 13a based on a comparison between the detection result of the first speed sensor 31 and the detection result of the second speed sensor 32.

[0089] Then, the control unit 43 of the equipment-in-use control system 1 controls the equipment 5 in accordance with the state of the tires 12a, 13a based on the air pressures of the tires 12a, 13a detected by the detection unit 42 (S13). Thereafter, the above steps S11 to S13 are repeated.

[0090] [Example of electric motor control] In the control example of the electric motor 45, similarly to the basic operation example, the acquisition unit 41 of the equipment control system 1 acquires speed information relating to the traveling speed of the vehicle body 10 (S21). Next, the detection unit 42 of the equipment control system 1 detects the air pressure of the tires 12a, 13a based on the speed information acquired by the acquisition unit 41 (S22).

[0091] In this control example, the control unit 43 of the equipment use control system 1 compares the air pressure of the tires 12a, 13a detected by the detection unit 42 with a threshold range (S23). The "threshold range" here refers to a threshold range having a certain width that includes the appropriate air pressure of the tires 12a, 13a.

[0092] If the air pressures of the tires 12a, 13a are below the threshold range (S23: Yes), the control unit 43 controls the electric motor 45 to increase the auxiliary driving force in accordance with the decrease in the air pressures of the tires 12a, 13a (S24). On the other hand, if the air pressures of the tires 12a, 13a are above the threshold range (S23: No, S25: Yes), the control unit 43 controls the electric motor 45 to decrease the auxiliary driving force in accordance with the increase in the air pressures of the tires 12a, 13a (S26). Also, if the air pressures of the tires 12a, 13a are within the threshold range (S25: No), the control unit 43 controls the electric motor 45 to maintain the current auxiliary driving force (S27). Thereafter, the above steps S21 to S27 are repeated while the user is riding on the vehicle body 10.

[0093] [Action and effect] The following describes the effects of the equipment use control system 1, the electric bicycle 2, the equipment use control method, and the program according to the embodiment.

[0094] As described above, the equipment use control system 1 according to the embodiment includes the acquisition unit 41, the detection unit 42, and the control unit 43. The acquisition unit 41 acquires speed information related to the traveling speed of the vehicle body 10. The detection unit 42 detects the air pressure of the tires 12a, 13a of the vehicle body 10 based on the speed information acquired by the acquisition unit 41. The control unit 43 controls the equipment use 5 used on the vehicle body 10 in accordance with the state of the tires 12a, 13a based on the air pressure of the tires 12a, 13a detected by the detection unit 42.

[0095] According to this, if the vehicle body 10 is equipped with a sensor capable of detecting speed information, the air pressures of the tires 12a, 13a can be detected in real time. Therefore, it is not necessary to use a device for detecting the air pressures of the tires 12a, 13a while the vehicle body 10 is stopped, or to mount a sensor on the vehicle body 10 for directly detecting the air pressures of the tires 12a, 13a. Furthermore, since the equipment 5 is controlled according to the state of the tires 12a, 13a based on the air pressures of the tires 12a, 13a, if there is an abnormality, such as a drop in the air pressure of the tires 12a, 13a, it is possible to suppress or eliminate the adverse effect of the abnormality on the vehicle body 10, or to notify the user of measures to eliminate the adverse effect. In this way, there is an advantage in that it is easy to improve the comfort of the user riding in the vehicle body 10.

[0096] The electric bicycle 2 according to the embodiment also includes a device control system 1 and an electric motor 45 that applies auxiliary driving force to assist the vehicle body 10 in traveling.

[0097] This electric bicycle 2 also provides the same effects as the equipment use control system 1 described above.

[0098] In addition, the method for controlling equipment used in the embodiment includes acquiring speed information regarding the traveling speed of the vehicle body 10, detecting the air pressure of tires 12a, 13a of the vehicle body 10 based on the acquired speed information, and controlling the equipment used 5 used in the vehicle body 10 in accordance with the state of tires 12a, 13a based on the detected air pressure of tires 12a, 13a.

[0099] This device use control method also provides the same effects as the device use control system 1 described above.

[0100] Furthermore, a program according to the embodiment causes one or more processors to execute the above-described method for controlling devices in use.

[0101] This program also provides the same effects as the above-described device use control system 1.

[0102] In the device usage control system 1 according to the embodiment, the acquisition unit 41 acquires, as speed information, a first detection result from the first speed sensor 31 that detects the speed of the wheels of the vehicle body 10 and a second detection result from the second speed sensor 32 that detects the speed of the vehicle body 10 using a positioning system. The detection unit 42 then detects the air pressures of the tires 12a, 13a based on a comparison between the first detection result and the second detection result.

[0103] This has the advantage that the air pressure of the tires 12a, 13a can be detected in real time while the vehicle body 10 is traveling.

[0104] In the equipment-used control system 1 according to the embodiment, the equipment-used 5 is an electric motor 45 that applies auxiliary driving force to assist the vehicle body 10 in traveling. The control unit 43 controls the electric motor 45 to adjust the auxiliary driving force according to the air pressure of the tires 12a, 13a.

[0105] According to this, even if the air pressure of the tires 12a, 13a has dropped, for example, by applying the same pedal force to the pedal 16 as when the air pressure of the tires 12a, 13a has not dropped, the vehicle body 10 can be driven at the same speed as when the air pressure of the tires 12a, 13a has not dropped. As a result, there is an advantage in that the load on the user can be reduced.

[0106] Furthermore, in the equipment use control system 1 according to the embodiment, the control unit 43 controls the electric motor 45 by further referring to the type of the tires 12a, 13a and the circumferential length of the tires 12a, 13a based on the air pressure of the tires 12a, 13a.

[0107] This has the advantage that it becomes easier to understand the effect that increases and decreases in air pressure of tires 12a, 13a have on the traveling speed of vehicle body 10, and it becomes easier to adjust the auxiliary driving force more appropriately according to the air pressure of tires 12a, 13a.

[0108] In the equipment-used control system 1 according to the embodiment, the equipment-used 5 is a transmission 51. The control unit 43 controls the transmission 51 to adjust the gear ratio according to the air pressure of the tires 12a and 13a.

[0109] This has the advantage that even when the air pressure in the tires 12a, 13a drops, the user can easily feel the same riding comfort as when the air pressure in the tires 12a, 13a does not drop.

[0110] In the equipment-used control system 1 according to the embodiment, the equipment 5 is a suspension 52. The control unit 43 controls the suspension 52 to adjust the damping force according to the air pressure of the tires 12a and 13a.

[0111] This has the advantage that even when the air pressure in the tires 12a, 13a drops, the user can easily feel the same riding comfort as when the air pressure in the tires 12a, 13a does not drop.

[0112] In the equipment-used control system 1 according to the embodiment, the equipment-used 5 is the air filling machine 3. The control unit 43 controls the air filling machine 3 so that the amount of air replenished into the tires 12a, 13a is adjusted according to the air pressures of the tires 12a, 13a.

[0113] This has the advantage of improving convenience, since the user can automatically adjust the air pressure of the tires 12a, 13a to an appropriate level without having to operate the air filling machine 3 to adjust the amount of air being refilled into the tires 12a, 13a.

[0114] In the usage equipment control system 1 according to the embodiment, the usage equipment 5 is a notification module 50 for communicating with the external device 9. The control unit 43 controls the notification module 50 to transmit status information relating to the status of the tires 12a, 13a to the external device 9.

[0115] This has the advantage that the external device 9 can acquire the status information, allowing the person handling the external device 9 (for example, a servicer) to know the status of the tires 12a, 13a of the vehicle body 10. Therefore, if an abnormality occurs in the tires 12a, 13a, for example, if the air pressure in the tires 12a, 13a is low, the servicer can take action such as performing maintenance such as repairing or adjusting the electric bicycle 2 in order to improve the status of the vehicle body 10. Furthermore, because the servicer can know when to perform such maintenance, he or she is no longer required to check the status of the vehicle body 10 every time.

[0116] In the equipment usage control system 1 according to the embodiment, the equipment usage 5 is a notification module 61a for notifying the surroundings of the vehicle body 10. The control unit 43 controls the notification module 61a so as to notify the surroundings of the vehicle body 10 of status information relating to the status of the tires 12a, 13a.

[0117] This has the advantage that the conditions of the tires 12a, 13a can be notified to the user riding in the vehicle body 10. Therefore, the user can know whether the conditions of the tires 12a, 13a are normal or abnormal. If the conditions of the tires 12a, 13a are abnormal, the user can easily perform maintenance, such as refilling the tires 12a, 13a with air or requesting a servicer to repair or adjust the vehicle body 10.

[0118] (Other variations, etc.) Although the present disclosure has been described above based on the embodiments, the present disclosure is not limited to these embodiments.

[0119] For example, in the above embodiment, the threshold value used for comparison with the air pressure of the tires 12a, 13a may differ depending on the type of vehicle body 10. For example, if the vehicle body 10 is a commuter bicycle, the threshold value may be set as the reference value, and if the vehicle body 10 is a mountain bike, the threshold value may be lower than the reference value. Also, if the vehicle body 10 is a road bike, the threshold value may be higher than the reference value. Furthermore, if the vehicle body 10 is a bicycle designed to carry relatively heavy luggage or children, the threshold value may be higher than the reference value.

[0120] Furthermore, the threshold value is not limited to a preset fixed value, but may be set as appropriate by, for example, a user. For example, the user may freely change the threshold value by executing an application for the device use control system 1 installed on an information terminal.

[0121] For example, in the above embodiment, the detection unit 42 detects the air pressure of the tires 12a, 13a based on a comparison between the first detection result of the first speed sensor 31 and the second detection result of the second speed sensor 32. However, this is not limiting. For example, the detection unit 42 may detect the air pressure of the tires 12a, 13a based on the acceleration of the wheels (front wheel 12 or rear wheel 13) in the Z-axis direction, in other words, the vibration in the up-down direction. That is, the vibration in the up-down direction of the wheels depends on the air pressure of the tires 12a, 13a and tends to increase as the air pressure of the tires 12a, 13a increases and decrease as the air pressure of the tires 12a, 13a decreases. Therefore, the detection unit 42 can detect the air pressure of the tires 12a, 13a based on the acceleration of the wheels in the Z-axis direction. In this case, the acquisition unit 41 may acquire the acceleration of the wheels in the Z-axis direction from, for example, a gyro sensor provided on the wheels.

[0122] For example, in the above embodiment, the acquisition unit 41, detection unit 42, and control unit 43 of the equipment usage control system 1 are mounted on the control device 40 of the electric bicycle 2, but this is not limited to this. For example, the acquisition unit 41, detection unit 42, and control unit 43 may be mounted on a location on the electric bicycle 2 other than the control device 40. Also, for example, the acquisition unit 41, detection unit 42, and control unit 43 may be mounted on an information terminal or server device. In this case, the information terminal or server device can also function as the notification module 50, and the notification module 50 is not necessary on the electric bicycle 2. In this case, the information terminal or server device can send and receive information to and from the electric bicycle 2 by wireless communication with the electric bicycle 2.

[0123] Furthermore, each processing unit used in the equipment control system 1 and the electric bicycle 2 according to each of the above-described embodiments is typically realized as an LSI, which is an integrated circuit. These may be individually implemented as single chips, or some or all of them may be integrated into a single chip.

[0124] Furthermore, the integration is not limited to LSI, but may be realized by dedicated circuits or general-purpose processors. FPGAs (Field Programmable Gate Arrays), which can be programmed after LSI fabrication, or reconfigurable processors, which allow the connections and settings of circuit cells within LSIs to be reconfigured, may also be used.

[0125] In each of the above embodiments, each component may be configured with dedicated hardware, or may be realized by executing a software program suitable for each component. Each component may also be realized by a program execution unit such as a CPU or processor reading and executing a software program recorded on a recording medium such as a hard disk or semiconductor memory.

[0126] Furthermore, all of the numbers used above are examples for specifically explaining the present disclosure, and the embodiments of the present disclosure are not limited to the numbers shown as examples.

[0127] The division of functional blocks in the block diagram is an example, and multiple functional blocks may be realized as a single functional block, one functional block may be divided into multiple blocks, or some functions may be moved to another functional block.Furthermore, the functions of multiple functional blocks having similar functions may be processed in parallel or in time-sharing by a single piece of hardware or software.

[0128] The order in which the steps in the flowchart are executed is merely an example for specifically explaining the present disclosure, and an order other than the above may be used. Also, some of the steps may be executed simultaneously (in parallel) with other steps.

[0129] In addition, this disclosure also includes forms obtained by making various modifications to the embodiments that a person skilled in the art would think of, and forms realized by arbitrarily combining the components and functions of the embodiments within the scope that does not deviate from the intent of this disclosure.
