[0051] The following description of each embodiment is merely an example of a possible form of the control device for a human-powered vehicle according to the present invention, and is not intended to limit the form. The control device for a human-powered vehicle according to the present invention may take forms different from those of each embodiment, such as a modified version of each embodiment, or a combination of at least two mutually compatible modified versions.

[0052] In the following description of each embodiment, terms expressing directions such as front, rear, forward, backward, left, right, lateral, up, and down are used based on the directions when a rider is seated in the saddle of the human-powered vehicle.

[0053] (First embodiment) Fig. 1 is a side view of a human-powered vehicle 1 to which a control device 100 in the first embodiment is applied. The human-powered vehicle 1 is a vehicle that uses human power at least in part as a driving force for traveling. Vehicles that use only an internal combustion engine or an electric motor as a driving force are excluded from the human-powered vehicle 1 of this embodiment. The human-powered vehicle 1 is, for example, a bicycle, including a mountain bike, road bike, cross bike, city cycle, and electrically assisted bike (e-bike).

[0054] The human-powered vehicle 1 includes a vehicle body 11, a handlebar 12, a front wheel 13, a rear wheel 14, and a seat 15. The human-powered vehicle 1 includes a drive mechanism 20, a device 30 (31 to 35), a battery 40, and sensors 50 (51 to 55).

[0055] The control unit 110 of the control device 100 controls the device 30 mounted on the human-powered vehicle 1. In one example, the control device 100 is mounted on the battery 40 of the human-powered vehicle 1, a cycle computer, a drive unit of an electrically assisted bicycle, or the like.

[0056] The control device 100 is connected to the device 30 and the battery 40. The connection state and the details of the control device 100 will be described later. (Note that in this specification, the objects to be controlled by the control device 100, including the device 30, may be simply referred to as "objects to be controlled.")

[0057] The vehicle body 11 includes a frame 11A and a front fork 11B. A front wheel 13 is rotatably supported by the front fork 11B. A rear wheel 14 is rotatably supported by the frame 11A. A handlebar 12 is supported by the frame 11A so that the traveling direction of the front wheel 13 can be changed.

[0058] The drive mechanism 20 transmits human-powered driving force to the rear wheel 14. The drive mechanism 20 includes a crank 21, a first sprocket assembly 22, a second sprocket assembly 23, a chain 24, and a pair of pedals 25.

[0059] The crank 21 includes a crankshaft 21A, a right crank 21B, and a left crank 21C. The crankshaft 21A is rotatably supported by the frame 11A. The right crank 21B and the left crank 21C are each connected to the crankshaft 21A. One of a pair of pedals 25 is rotatably supported by the right crank 21B. The other of the pair of pedals 25 is rotatably supported by the left crank 21C.

[0060] The first sprocket assembly 22 is connected to the crankshaft 21A so as to be rotatable together with the crankshaft 21A. The first sprocket assembly 22 includes one or more sprockets 22A. In one example, the first sprocket assembly 22 includes a plurality of sprockets 22A having different outer diameters.

[0061] The second sprocket assembly 23 is rotatably supported on the rear hub of the rear wheel 14. The second sprocket assembly 23 includes one or more sprockets 23A. In one example, the second sprocket assembly 23 includes multiple sprockets 23A with different outer diameters.

[0062] The chain 24 is wound around one of the sprockets 22A of the first sprocket assembly 22 and one of the sprockets 23A of the second sprocket assembly 23. When the crank 21 rotates forward due to a human driving force applied to the pedal 25, the first sprocket assembly 22 rotates forward together with the crank 21, and the rotation of the first sprocket assembly 22 is transmitted to the second sprocket assembly 23 via the chain 24, which rotates the rear wheel 14. Instead of the chain 24, a belt or a shaft may be used.

[0063] The human-powered vehicle 1 is operated by power supplied from a battery 40 and includes a device 30 whose operation is controlled by a control device 100. The device 30 includes at least a gear change device 32. The device 30 includes an assist mechanism 31 and a braking device 33. The device 30 may also include an electric suspension and an electric seat post, not shown. The device 30 includes a locking device 34. The locking device 34 is a device related to the security of the human-powered vehicle 1. The device 30 basically operates under the control of the control device 100 in accordance with the operation of an operating device 35.

[0064] The assist mechanism 31 is a component that assists in the propulsion of the human-powered vehicle 1. In one example, the assist mechanism 31 is interposed between the crankshaft 21A and the frame 11A, and transmits torque to the first sprocket assembly 22 to assist in the propulsion of the human-powered vehicle 1. The assist mechanism 31 runs a chain 24 that transmits driving force to the rear wheel 14 of the human-powered vehicle 1.

[0065] The transmission 32 is a device configured to be able to change the gear ratio in the drive mechanism 20 of the human-powered vehicle 1. The transmission 32 changes the ratio of the rotation speed of the rear wheel 14 to the rotation speed of the crank 21, i.e., the gear ratio. In a first example, the transmission 32 is an externally mounted transmission including a rear derailleur 32B that changes the connection state between the second sprocket assembly 23 and the chain 24. In a second example, the transmission 32 is an externally mounted transmission including a front derailleur 32A that changes the connection state between the first sprocket assembly 22 and the chain 24. In a third example, the transmission 32 is an externally mounted transmission including both the front derailleur 32A and the rear derailleur 32B.

[0066] 2 and 3 are enlarged views of the front derailleur 32A and the rear derailleur 32B, respectively. The front derailleur 32A includes a guide member 32C that contacts the chain 24 and a motor 32E. The rear derailleur 32B includes a guide member 32D that contacts the chain 24 and a motor 32F. The front derailleur 32A and the rear derailleur 32B guide the chain 24 (not shown) along the guide members 32C and 32D, respectively, and move the chain 24 between sprockets 22A or 23A that have different outer diameters. Specifically, the guide members 23C and 32D are driven in the left-right direction (the front-back direction on the paper in FIGS. 2 and 3) relative to the traveling direction of the human-powered vehicle 1, and move the chain 24 between the sprockets 22A or 23A.

[0067] Motors 32E and 32F are controlled by control device 100 to drive front derailleur 32A and rear derailleur 32B, respectively. In this embodiment, motors 32E and 32F drive guide members 32C and 32D, respectively. Motors 32E and 32F can be controlled by a PWM (Pulse Width Modulation) signal output from control device 100. The outputs of motors 32E and 32F vary according to the duty ratio of the pulse wave of the PWM signal, and decrease when the duty ratio decreases.

[0068] In a first example, the braking device 33 is a rim brake provided on the front wheel 13 and the rear wheel 14. In a second example, the braking device 33 is a disc brake. The braking device 33 can be connected to a brake lever (operating device 35) provided on the handlebar 12.

[0069] The locking device 34 is a device that switches the state of the human-powered vehicle 1 from one of a locked state and an unlocked state to the other. The locked state is a state in which at least one of the operation of the human-powered vehicle 1 and the operation of the device 30 mounted on the human-powered vehicle 1 is restricted. The unlocked state is a non-restricted state in which restrictions on the operation of the human-powered vehicle 1 and the device 30 are released.

[0070] As an example, the locking device 34 is provided for the rear wheel 14. The locking device 34 includes a drive circuit and an electric actuator (neither shown). The drive circuit drives the electric actuator in response to a locking operation by the rider, thereby physically restricting the rotation of the rear wheel 14. The locking device 34 releases the drive of the electric actuator in response to an unlocking operation by the rider, thereby allowing the rotation of the rear wheel 14. The locking and unlocking operations by the rider may be performed using a physical key, or may be performed by inputting an electronic key into the operation device 35.

[0071] The lock device 34 may have a function of notifying the information processing device 3 via the control device 100 that there is a risk of theft when it detects an operation other than a valid operation or an unlocking operation using a corresponding key or electronic key.

[0072] The operation device 35 is provided on the handlebar 12. The operation device 35 includes, for example, an operation unit 35A that is operated by the rider. One example of the operation unit 35A is one or more buttons. Another example of the operation unit 35A is a brake lever. Operation is possible by tilting the brake levers provided on the left and right handlebars to the left and right. The information terminal device 5 may be used as the operation unit 35A. Operation buttons are displayed on a display panel included in the information terminal device 5, and when the information terminal device 5 detects that an operation button has been selected, it notifies the control device 100.

[0073] The operation device 35 includes a gear shift indicator 35B. The gear shift indicator 35B is one of a plurality of buttons. The gear shift indicator 35B is a button-shaped device attached to the brake bar. Each time the rider presses the gear shift indicator 35B, the gear ratio can be increased or decreased.

[0074] The operation device 35 includes a notification unit 35C that notifies an operating state. The notification unit 35C uses an LED (Light Emitting Diode) to indicate whether it is on (lit) or off (unlit).

[0075] The operation device 35 is communicatively connected to the device 30 so as to transmit signals corresponding to operations of the operation unit 35A and the gear shift instruction device 35B to the device 30. In a first example, the operation device 35 communicates with the device 30 and the control device 100 via a communication line or an electric wire capable of PLC (Power Line Communication). In a second example, the operation device 35 communicates with the device 30 and the control device 100 via wireless communication.

[0076] The battery 40 includes a battery body 41 and a battery holder 42. The battery body 41 is a storage battery including one or more battery cells.

The battery 40 is electrically connected to the device 30 and the control device 100, and supplies power as required. The battery 40 preferably includes a control unit for communicating with the control device 100. The control unit preferably includes a processor using a CPU.

[0077] The human-powered vehicle 1 is provided with sensors 50 for detecting conditions at various locations. The sensors 50 include a speed sensor 51, an acceleration sensor 52, a torque sensor 53, a cadence sensor 54, a GPS (Global Positioning System) sensor 55, and the like.

[0078] The speed sensor 51 is provided on the front wheel 13, and calculates the speed from the number of rotations per unit time of the front wheel 13, and notifies the control device 100 and the device 30 of the calculated speed.

[0079] The acceleration sensor 52 is fixed to the frame 11A. The acceleration sensor 52 is a sensor that outputs vibrations of the human-powered vehicle 1. It is provided to detect the toppling over of the stopped human-powered vehicle 1 and vibrations caused by an impact to the human-powered vehicle 1. The acceleration sensor 52 notifies the control device 100 and the device 30 of a signal corresponding to the magnitude of the vibration.

[0080] The torque sensor 53 is provided to measure the torque applied to the right crank 21B and the left crank 21C, respectively. The torque sensor 53 notifies the control device 100 and the device 30 of a signal indicative of the torque measured at at least one of the right crank 21B and the left crank 21C.

[0081] The cadence sensor 54 is provided to measure the cadence of either the right crank 21 B or the left crank 21 C. The cadence sensor 54 notifies the control device 100 and the device 30 of a signal indicating the measured cadence.

[0082] The GPS sensor 55 is fixed to the frame 11A. The GPS sensor 55 is a sensor that calculates position data of the human-powered vehicle 1 based on a GPS signal. The GPS sensor 55 periodically calculates the position data and notifies the control device 100 and the device 30 of a signal indicating the position data.

[0089] The communication that control unit 110 performs with the controlled object is not limited to wired communication, but may be wireless communication such as ANT (registered trademark), ANT+ (registered trademark), Bluetooth (registered trademark), WiFi (registered trademark), ZigBee (registered trademark), or the like.

[0090] The control unit 110 is connected to the sensor 50 via a signal line. The control unit 110 obtains data relating to the status from a signal output by the sensor 50 via the signal line.

[0091] The control unit 110 may communicate with the information processing device 4 described later via a wireless communication device 60 having an antenna. The wireless communication device 60 may be built into the control device 100. The wireless communication device 60 is a device that realizes so-called communication via the Internet. The wireless communication device 60 may be a device for wireless communication such as ANT (registered trademark), ANT+ (registered trademark), Bluetooth (registered trademark), WiFi (registered trademark), ZigBee (registered trademark), LTE (Long Term Evolution), etc. The wireless communication device 60 may be compliant with a communication network such as 3G, 4G, 5G, LTE (Long Term Evolution), WAN (Wide Area Network), LAN (Local Area Network), Internet line, dedicated line, satellite line, etc. The control unit 110 may communicate with the information processing device 4 using a transmission / reception function of the information terminal device 5 of the rider.

[0092] When the human-powered vehicle 1 is in the first state, the control unit 110 of the control device 100 causes the transmission 32 to execute a first behavior that makes the driving of the human-powered vehicle 1 inefficient. The first state is a state in which the human-powered vehicle 1 is being used illegally or there is a risk of this happening, and more specifically, a state in which the human-powered vehicle 1 has been stolen. However, the first state is not necessarily limited to a stolen state, but also includes cases in which the rider does not have legitimate riding authority, such as when the expiration date of a rental cycle or a shared bike has passed, or when a legitimate user wants to restrict the use of the human-powered vehicle 1. Details of the first behavior will be described later.

[0093] The determination as to whether or not it is in the first state is made based on, for example, the following criteria. When the human-powered vehicle 1 is in a locked state and a predetermined vibration is applied to the acceleration sensor 52 When the human-powered vehicle 1 is in a locked state and a predetermined load is applied to the torque sensor 53 When the position data of the human-powered vehicle 1 acquired by the GPS sensor 55 indicates a location where the human-powered vehicle 1 should not be located When the human-powered vehicle 1 has exceeded the specified usage time. In the above case, it is presumed that the human-powered vehicle 1 has been unlocked, disassembled, moved, or the like by fraud, and it can be determined that the vehicle is in the first state.

[0094] The control unit 110 may determine by itself whether or not the human-powered vehicle 1 is in the first state, or may recognize whether or not the human-powered vehicle 1 is in the first state upon receiving a notification from an information processing device 4, which will be described later.

[0095] FIG. 5 is a diagram showing the control device 100 and the information processing device 4 of the first embodiment. As shown in FIG. 5, the control device 100 of the first embodiment can communicate with the information processing device 4 via a communication network N. The communication network N is composed of communication lines such as 3G, 4G, 5G, LTE, WAN, LAN, Internet lines, dedicated lines, satellite lines, and communication facilities such as base stations. The control device 100 may use an information terminal device 5 configured to be able to communicate with the information processing device 4 via the communication network N. The information terminal device 5 is, for example, a smartphone or cycle computer used by the rider of the human-powered vehicle 1, and can also function as a user interface for inputting instructions from the rider and outputting information to the rider.

[0096] The control device 100 outputs a control signal to the devices 30 based on the operation of the operation device 36 of the human-powered vehicle 1. When the control device 100 is started by the operation of the rider, it checks the status of the human-powered vehicle 1 with the information processing device 4. The control device 100 outputs a signal to at least one of the devices 30 according to the determination result of whether or not the status of the human-powered vehicle 1 obtained from the information processing device 4 is in the first state.

[0097] 6 is a block diagram showing the configuration of the information processing device 4. The information processing device 4 includes a control unit 400, a storage unit 402, and a communication unit 404.

[0098] The control unit 400 is a processor using a CPU. The control unit 400 may use a GPU (Graphics Processing Unit). The control unit 400 may use a CPU and a GPU. The control unit 400 uses built-in memories such as a ROM and a RAM to transmit and receive data to and from the control device 100 and executes a process of determining the status.

[0099] The control unit 400 may be one or more processing circuits including a field programmable gate array (FPGA), a digital signal processor (DSP), a quantum processor, a volatile or non-volatile memory, and the like.

[0100] The storage unit 402 is a large-capacity non-volatile memory such as a hard disk or SSD (Solid State Drive). The storage unit 402 stores management data for each of the multiple human-powered vehicles 1. The management data includes data for identifying a legitimate user in association with the identification data. The storage unit 402 may store the management data for each human-powered vehicle A in advance, or may obtain and store the data from the control device 100, or may obtain and store the data from an information terminal device 5 used by a legitimate user.

[0101] The communication unit 404 is a communication device that communicates with the control device 100 via the network N. The communication unit 404 complies with communication networks such as 3G, 4G, 5G, LTE, WAN, LAN, an Internet line, a dedicated line, and a satellite line. The control unit 400 transmits and receives data to and from the control device 100 via the communication unit 404.

[0102] The control device 100 and information processing device 4 configured as above determine the state of the human-powered vehicle 1. The state determination is executed by comparing data held by the control device 100 with data held by the information processing device 4.

[0103] 7 shows an example of the contents of management data stored in the storage unit 402 of the information processing device 4. The management data includes a user ID for identifying a legitimate user of the human-powered vehicle 1 and the device 30, in association with the identification data of the human-powered vehicle 1. The management data includes status data relating to the status of at least one of the human-powered vehicle 1 and the device 30, in association with the identification data.

[0104] The identification data stored in the information processing device 4 includes at least one of the manufacturer name, distributor name, product name, model number, production date, and serial number. The identification data can also be read from a two-dimensional code attached to at least one of the human-powered vehicle A and the component C.

[0105] At least one of user data of a legitimate user, including a name, a date of birth, a telephone number, an email address, a password, and biometric information, is associated with the user ID stored in the information processing device 4. The user data may include at least one of a legitimate user's name, a date of birth, a telephone number, an email address, a password, and biometric information.

[0106] The status data indicates, for example, a status such as "normal", "locked", or "stolen". "Normal" means that the human-powered vehicle 1 has not been stolen and is being used normally. "Locked" means that the operation of at least one of the human-powered vehicle 1 and the device 30 is physically or electronically restricted. "Locked" includes a state in which the front wheels 13 or the rear wheels 14 are locked. When the control device 100 sets the vehicle in a locked state using the lock device 34, it notifies the information processing device 4 of the "locked" state, and the information processing device 4 updates the status with the notified "locked" state. The status "stolen" means that the human-powered vehicle 1 has been stolen. The status data is stored as management data by the information processing device 4, for example, based on a notification to the information processing device 4 from a legitimate user.

[0107] If the control device 100 has a function for determining a theft state, the control device 100 may notify the information processing device 4 of a status of "theft in progress", and the information processing device 4 may update the status data. To release the status of "theft in progress", an authorized user needs to request the release from the information processing device 4 together with authentication data such as a password.

[0108] The example in FIG. 7 shows that for the human-powered vehicle 1 identified by the identification data "B001", the user data of the authorized user is "U001" and the status data indicates "normal".

[0109] 7, the status data associated with the identification data of “B003” indicates “being stolen.” The human-powered vehicle 1 identified by the identification data of “B003” is stored as being “being stolen” upon notification from a legitimate user or the control device 100.

[0110] 8 is a flow chart showing an example of the first behavior of the human-powered vehicle 1 in the first embodiment. When started up, the control unit 110 of the control device 100 executes the following processes based on a control program P1 stored in the storage unit 112.

[0111] The control unit 110 reads out the identification data of the human-powered vehicle 1 stored in the storage unit 112 (step S101), and transmits the identification data to the information processing device 4 (step S103).

[0112] When the information processing device 3 receives the identification data of the human-powered vehicle 1 from the control device 100, it responds to the control device 100 with status data associated with the identification data.

[0113] The control unit 110 of the control device 100 receives the status data returned from the information processing device 4 (step S105), and determines whether the status data is "theft in progress" (step S107).

[0114] If it is determined that the status data is not "Theft in progress" (S107: NO), the control unit 110 determines whether or not the lock device 34 is in an unlocked state (step S109).

[0115] If it is determined that the lock is not released (S109: NO), the control unit 110 determines whether there is a risk of theft (step S111).

[0116] If it is determined in step S111 that there is no risk of theft (S111: NO), the control unit 110 returns the process to step S109.

[0117] If it is determined in step S111 that there is a risk of theft (S111: YES), the control unit 110 advances the process to step S121, which will be described later.

[0118] If it is determined in step S109 that the vehicle is in the unlocked state (S109: YES), the control unit 110 accepts data for identifying the rider through an operation by the rider on the operation device 36 (or the information terminal device 5) (step S113). In step S113, the rider inputs, for example, a name, a PIN number, or biometric information into the operation device 36.

[0119] The control unit 110 transmits the received rider data for identifying the rider to the information processing device 4 in association with the identification data of the human-powered vehicle 1 (step S115).

[0120] The information processing device 4 receives the rider data and refers to the user ID stored in association with the identification data of the human-powered vehicle 1 in the management data of the storage unit 402. The control unit 400 of the information processing device 4 determines whether the user ID matches the data of a legitimate user associated with the user ID, and responds with the determination result to the control device 100.

[0121] The control unit 110 of the control device 100 determines whether the transmitted LIDAR data matches the authentic user data based on the response from the information processing device 4 (step S117).

[0122] If it is determined that there is a match (S117: YES), the control unit 110 determines that the rider is a legitimate rider, starts normal control over the device 30 (step S119), and ends the process.

[0123] If it is determined that they do not match (S117: NO), the control unit 110 determines that the rider is not a legitimate rider and is at risk of theft, and notifies the information processing device 4 of the status data "being stolen" in association with the identification data (step S121). If the control unit 110 determines in step S111 that there is a risk of theft, a notification is also given (S121).

[0124] The control unit 110 causes the transmission 32 to execute the first behavior (step S123), and ends the processing.

[0125] In the first behavior, the control unit 110 controls at least one of the rear derailleur 32B and the front derailleur 32A to limit movement of the chain 24 between the multiple sprockets 22A or 23A. For example, the control unit 110 does not drive the front derailleur 32A or the rear derailleur 32B. Specifically, the control unit 110 does not send a drive signal to the motor 32E or 32F.

[0126] In the first behavior, controller 110 may control front derailleur 32A or rear derailleur 32B to limit the drive of guide member 32C or 32D of front derailleur 32A or rear derailleur 32B. In this case, for example, a physical obstacle such as a stopper may be inserted in the path of force transmission from motor 32E or 32F to guide member 32C or 32D to inhibit the drive of guide member 32C or 32D regardless of the magnitude of the output of motor 32E or 32F.

[0127] In the first behavior, controller 110 may reduce the output of motor 32E or 32F that drives front derailleur 32A or rear derailleur 32B. In this case, for example, if motor 32E or 32F is controlled by PWM control, controller 110 may reduce the duty ratio of the pulse wave input to motor 32E or 32F. If the duty ratio of the pulse wave is sufficiently small, the drive amount of motor 32E or 32F becomes small, and derailleurs 32A, 32B cannot move chain 24 sufficiently, making it impossible to complete gear shifting. In this embodiment, an internal transmission may be used instead of the external transmission. In this case, the drive of the gears included in the internal transmission or the motor that drives the gears is prohibited, inhibited, or limited in the same manner as described above.

[0128] In the case of manual shifting, the control unit 110 normally performs a gear shift in response to a gear shift instruction to shift up or down transmitted from the gear shift instruction device 35B of the operation device 35. In the case of automatic gear shifting, a control program determined to perform a gear shift under a predetermined condition is regarded as the gear shift instruction device 35B. However, in the first state, the control unit 110 is configured to execute a different behavior even if it receives a gear shift instruction from the gear shift instruction device 35B. Alternatively, in the first state, the control unit 110 may be configured to ignore the gear shift instruction from the gear shift instruction device 35B and not perform a gear shift in the first place.

[0129] In this way, by restricting gear shifting operations against the rider's will, it becomes difficult for the rider to ride, which can discourage the rider from riding the bicycle.

[0130] Second embodiment In the second embodiment, another form of the first behavior of the human-powered vehicle 1 will be described. In the second embodiment, the first behavior is the execution of a gear shift against the rider's will. The configurations of the human-powered vehicle 1 and the control device 100 are similar to those of the first embodiment, except for the control content for the first behavior, which will be described later, and therefore detailed description will be omitted.

[0131] 9 is a flowchart showing an example of the first behavior of the human-powered vehicle 1 in the second embodiment. The processing procedure shown in the flowchart in FIG. 9 corresponds to details of the processing of step S123 in the flowchart in FIG.

[0132] The control unit 10 determines whether or not a gear ratio has been instructed by the gear shift indicator 35B (step S231). If it is determined that a gear ratio has not been instructed (S231: NO), the control unit 110 returns the process to step S231 and waits until it is determined that a gear ratio has been instructed.

[0133] If it is determined in step S231 that a gear ratio has been instructed by the gear change instruction device 35B (S231: YES), the control unit 110 identifies the first gear ratio instructed by the rider of the human-powered vehicle 1 (step S233). The control unit 10 controls the transmission C2 so that the gear ratio in the transmission C2 becomes a second gear ratio different from the first gear ratio identified in step S233 (step S235).

[0134] Specifically, in step S235, control unit 10 controls at least one of front derailleur 32A and rear derailleur 32B so that the gear ratio in transmission C2 becomes the second gear ratio. In this embodiment, an internal transmission can be used instead of the external transmission.

[0135] The control unit 10 returns the process to step S231, and controls the transmission 32 so that the second gear ratio becomes different from the instructed first gear ratio every time a gear ratio is instructed.

[0136] The control unit 10 repeats the processes from steps S231 to S235 until the power supply is turned off.

[0137] In the second embodiment, the human-powered vehicle 1 may execute the following first behavior in addition to the processing shown in the flowchart of FIG.

[0138] The control unit 110 may control the transmission 32 in the first behavior so that the gear ratio is fixed to a specific third gear ratio, regardless of an instruction by the rider of the human-powered vehicle 1 to the operating device 35. In other words, the control unit 110 of the control device 100 fixes the gear ratio, for example, to a third gear ratio that is greater than half the maximum gear ratio, regardless of whether an instruction to shift up or down is received. For example, in a human-powered vehicle 1 with 10 gears, the number of gears is fixed to 6 or more. The control unit 110 may fix the gear ratio, for example, to the third gear ratio, which is the maximum gear ratio. For example, in a human-powered vehicle 1 with 10 gears, the number of gears is fixed to 10.

[0139] 10 is a flowchart showing another example of the first behavior of the human-powered vehicle 1 in the second embodiment. The processing procedure shown in the flowchart in FIG. 10 corresponds to details of the processing of step S123 in the flowchart in FIG.

[0140] The control unit 110 determines the traveling speed of the human-powered vehicle 1 based on a signal from the speed sensor 51 (step S301).

[0141] The control unit 110 judges whether the determined traveling speed is included in a first speed range (step S303). The first speed range is, for example, a speed range from 0 km / h to 5 km / h that can be judged as the start of driving. The first speed range may be, for example, from 1 km / h to 6 km / h, or may be another range, and is stored in advance in the storage unit 112 according to each type of human-powered vehicle 1.

[0142] If it is determined in step S303 that the traveling speed is within the first speed range (S303: YES), the control unit 10 controls the transmission 32 to relatively increase the gear ratio in the drive mechanism 20 (step S305). The control unit 110 returns the process to step S301.

[0143] In step S305, for example, the control unit 110 increases the gear ratio by one to the maximum difference step, or increases it up to the maximum gear ratio, regardless of whether or not there is a gear ratio instruction for the transmission 32 from the gear shift instruction device 35B. In another example, when the speed is within the first speed range, the control unit 110 controls the transmission 32 so that the gear ratio is fixed to the maximum gear ratio in the drive mechanism 20. For example, in the case of a human-powered vehicle 1 with 10 gears, the number of gears is fixed to 10 while the speed is within a speed range that can be determined to be the start of driving.

[0144] If it is determined in step S303 that the traveling speed is not within the first speed range (S303: NO), the control unit 110 determines whether the determined traveling speed is within the second speed range (step S307). The second speed range is a speed range that is faster than the upper limit of the first speed range. The second speed range is, for example, greater than 5 km / h. In other examples, the second speed may be greater than 6 km / h or may be in another range. A range faster than the first speed range is pre-stored in the storage unit 112 for each type of human-powered vehicle 1.

[0145] If it is determined in step S307 that the traveling speed is included in the second speed range (S307: YES), the control unit 110 controls the transmission 32 to relatively reduce the gear ratio in the drive mechanism 20 (step S309). For example, when the speed reaches a range faster than when the driving started, the control unit 110 reduces the number of gears against the rider's will, although the number should normally be increased. The control unit 110 returns the process to step S301.

[0146] In step S309, for example, the control unit 110 reduces the gear ratio by one to the maximum difference step, or reduces it to the minimum gear ratio, regardless of whether or not there is a gear ratio instruction for the transmission 32 from the gear shift instruction device 35B. In another example, the control unit 10 controls the transmission C2 so that the gear ratio is fixed to the minimum gear ratio in the drive mechanism B when it is within the second speed range. For example, in the case of a human-powered vehicle 1 with 10 gears, when the speed reaches a range faster than when driving started, the number of gears is fixed to 1.

[0147] When it is determined in step S307 that the traveling speed is not included in the second speed range (S307: NO), the control unit 110 returns the process to step S301. The control unit 110 repeats the processes of steps S301 to S309 until the power is turned off.

[0148] Fig. 11 is a flowchart showing another example of the first behavior of the human-powered vehicle 1 in the second embodiment. The processing procedure shown in the flowchart of Fig. 11 corresponds to the details of the processing of step S123 in the flowchart of Fig. 8. Among the processing procedures shown in the flowchart of Fig. 11, those procedures common to the processing procedures shown in the flowchart of Fig. 9 are assigned the same step numbers and detailed descriptions thereof will be omitted.

[0149] In the modified example, when it is determined in step S231 that the gear ratio has been instructed by the gear shift instructing device 35B (S231: YES), the control unit 110 ignores the gear shift instruction transmitted from the gear shift instructing device 35B (step S237) and returns the process to step S231. The control unit 10 repeats the processes of steps S231 and S237 until the power is turned off.

[0150] In this way, even if an operation to indicate a gear ratio is performed with the gear shift indicator 35B, the control unit 110 does not perform a corresponding process. Even if a rider who has stolen the human-powered vehicle 1 starts driving and attempts to change gears with the transmission 32, the gears are not changed.

[0151] In this way, a gear change operation that goes against the rider's will makes it difficult for the rider to ride, which can discourage the rider from riding the bicycle.

[0152] Third embodiment In the third embodiment, another form of the first behavior of the human-powered vehicle 1 will be described. In the third embodiment, the first behavior is a movement of the chain 24 that impedes travel. The configurations of the human-powered vehicle 1 and the control device 100 are similar to those of the first embodiment, except for the control content for the first behavior, which will be described later, and therefore detailed description will be omitted.

[0153] In the third embodiment, in the first behavior, the control unit 110 controls the front derailleur 32A or rear derailleur C32B of the transmission 32 to move the chain 24 to its movable limit. The control unit 110 of the control device 100 moves the chain B4 to its movable limit in step S123 in the flowchart of Fig. 8. For example, when the chain 24 is hung on a predetermined sprocket 22A, 23A, the control unit 110 moves the chain 24 in one go to the outermost sprocket 22A, 23A or the innermost sprocket 22A, 23A.

[0154] The control unit 10 controls the front derailleur 32A or rear derailleur 32B to move the chain 24 until it reaches a predetermined first movement amount. For example, in the case of the rear derailleur 32B, the first movement amount is an amount of movement in which the chain 24 is moved between five or more sprockets 23A. In this case, unlike a multi-speed shift that shifts gears in stages, the chain 24 is moved all at once.

[0155] By moving chain 24 as described above, control unit 10 may control front derailleur 32A or rear derailleur 32B to move chain 24 until a jam occurs in chain 24. Control unit 110 may control at least one of front derailleur 32A and rear derailleur 32B to move chain 24 to a location where chain 24 disengages from at least one of sprockets 22A and 23A.

[0156] In this way, movement of the chain 24 against the rider's will makes it difficult for the rider to ride, and can discourage the rider from riding.

[0157] The embodiments disclosed herein are illustrative in all respects and should not be considered as limiting. The scope of the present invention is defined by the claims, not by the above meaning, and is intended to include all modifications within the scope and meaning equivalent to the claims.
