For example, the inverter circuit includes a configuration in which a plurality of inverter sections, each consisting of a pair of transistors connected in series, are connected in parallel. The inverter circuit may have a current sensor that detects the current flowing through the inverter circuit. For example, the current sensor is communicated with the control unit 72 by wire or wirelessly. For example, when the control unit 72 and the current sensor communicate by wire, the control unit 72 and the current sensor communicate by power line communication (PLC), CAN, or UART.

[0049] For example, the human-powered vehicle 10 further includes a human-powered force detection unit 54.

For example, if the human-powered driving force detection unit 54 is provided on the transmission member 38, the human-powered driving force detection unit 54 may include a sensor that detects the tension of the chain.

[0052] For example, the human-powered vehicle 10 further includes a crank rotation state detection unit 56.

[0053] For example, the crank rotation state detection unit 56 includes a magnetic sensor that outputs a signal corresponding to the strength of the magnetic field. For example, the magnetic sensor includes an annular magnet whose magnetic field strength changes in the circumferential direction. For example, the annular magnet whose magnetic field strength changes in the circumferential direction is provided between the crankshaft 20, a member that rotates in conjunction with the crankshaft 20, or a transmission path from the crankshaft 20 to the first rotating body 34.

[0054] For example, the crank rotation state detection unit 56 outputs a signal corresponding to the rotation speed C of the crankshaft 20. For example, the magnet may be provided on a member that rotates integrally with the crankshaft 20 in the transmission path of human-powered driving force from the crankshaft 20 to the first rotating body 34. For example, the crank rotation sensor may include an optical sensor, an acceleration sensor, a gyro sensor, or a torque sensor instead of a magnetic sensor.

[0055] For example, the crank rotation state detection unit 56 is configured to output a predetermined number of detection signals during one rotation of the crankshaft 20. For example, the predetermined number of signals is 2 or more. For example, the predetermined number of signals is 4 or more. For example, the predetermined number of signals is a multiple of 4.

[0058] For example, the vehicle speed detection unit 58 is configured to output a predetermined number of detection signals during one rotation of the wheel 12. For example, the predetermined number is 1. For example, the vehicle speed detection unit 58 outputs a signal corresponding to the rotational speed W of the wheel 12. For example, the control unit 72 can calculate the vehicle speed of the human-powered vehicle 10 based on the signal corresponding to the rotational speed W of the wheel 12 and information regarding the circumference of the wheel 12.

For example, the control unit 72 may determine whether or not the change in the gear ratio R is complete, based on the rotational speed C of the crank 18 and the rotational speed W of the wheel 12. If the human-powered driving force is above a predetermined threshold, the control unit 72 calculates the gear ratio R from the rotational speed C of the crank 18 and the rotational speed W of the wheel 12.

[0060] For example, if the gear shifting state detection unit 60 includes a derailleur, it outputs a signal corresponding to the position of the derailleur. The gear shifting state detection unit 60 may also output a signal corresponding to the operating position of an operating device that is configured to operate the gear shifting device 48.

For example, the gear shifting state detection unit 60 includes at least one of a magnetic sensor, an optical sensor, and a potentiometer. For example, the gear shifting state detection unit 60 is communicated with the control unit 72 by wire or wireless. For example, if the control unit 72 and the gear shifting state detection unit 60 communicate by wire, the control unit 72 and the gear shifting state detection unit 60 communicate by power line communication (PLC), CAN, or UART.

[0061] For example, the human-powered vehicle 10 includes a saddle load detection unit 62. The saddle load detection unit 62 is provided on the saddle 16A. The saddle load detection unit 62 is configured to detect the load applied to the saddle 16A. The saddle load detection unit 62 may be configured to detect information relating to at least one of the load on the front of the saddle 16A, the load on the rear of the saddle 16A, and the ratio of the load on the front of the saddle 16A to the load on the rear of the saddle 16A.

For example, at least one detection element may be positioned elsewhere than the surface of the saddle 16A, as long as it can detect information related to the distribution of the load applied to the saddle 16A.

[0063] For example, the saddle load detection unit 62 is connected to the control unit 72 via wired or wireless communication. For example, when the control unit 72 and the saddle load detection unit 62 communicate via wired communication, the control unit 72 and the saddle load detection unit 62 communicate via power line communication (PLC), CAN, or UART.

[0064] For example, the human-powered vehicle 10 includes a suspension operating state detection unit 64. For example, the suspension operating state detection unit 64 is configured to detect the operating state of the suspension 44. For example, the suspension operating state detection unit 64 is configured to detect a locked state and an unlocked state. For example, the suspension operating state detection unit 64 is configured to detect at least one of the internal pressure, spring load, and pressure state from the spring at the contact portion with the spring of the suspension 44.

[0065] For example, the suspension operation state detection unit 64 is connected to the control unit 72 via wired or wireless communication.

[0066] For example, the human-powered vehicle 10 includes a tilt angle detection unit 66. For example, the tilt angle detection unit 66 is configured to detect the pitch angle of the human-powered vehicle 10. For example, the tilt angle detection unit 66 is configured to output a signal corresponding to the pitch angle of the human-powered vehicle 10 to the control device 70. For example, the pitch angle of the human-powered vehicle 10 corresponds to the gradient of the road on which the human-powered vehicle 10 travels. For example, the control unit 72 calculates the gradient of the road on which the human-powered vehicle 10 travels according to the pitch angle of the human-powered vehicle 10.

[0067] For example, the tilt angle detection unit 66 includes at least one of a gyro sensor, an accelerometer, and a Global Navigation Satellite System (GNSS) receiver. For example, the Global Navigation Satellite System (GNSS) receiver includes a Global Positioning System (GPS) receiver. The Global Navigation Satellite System (GNSS) receiver may also include a receiver for a satellite positioning system other than GPS.

[0068] For example, the inclination angle detection unit 66 may detect the gradient of the road the human-powered vehicle 10 is traveling on at the current location as a pitch angle, based on GPS information acquired by the GPS receiver and map information including information about the gradient of the road the human-powered vehicle 10 is traveling on. For example, the control unit 72 may calculate the gradient of the road the human-powered vehicle 10 is traveling on, based on GPS information acquired by the GPS receiver and map information including information about the gradient of the road the human-powered vehicle 10 is traveling on. For example, the map information including information about the gradient of the road the human-powered vehicle 10 is traveling on is stored in the storage unit 74.

[0069] For example, the tilt angle detection unit 66 is connected to the control unit 72 via wired or wireless communication. For example, when the control unit 72 and the tilt angle detection unit 66 communicate via wired communication, the tilt angle detection unit 66 and the control unit 72 communicate via power line communication (PLC), CAN, or UART.

[0070] The control unit 72 is configured to control the notification unit 52. For example, the display unit 52A is configured to display first information relating to the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and at least one of the riders of the human-powered vehicle 10 on the display screen 52B.

[0071] For example, the control unit 72 is configured to display first information corresponding to at least one detection result from the human power driving force detection unit 54, the crank rotation state detection unit 56, the vehicle speed detection unit 58, the gear shift state detection unit 60, the saddle load detection unit 62, the suspension operation state detection unit 64, and the tilt angle detection unit 66 on the display unit 52A.

[0072] For example, the first information includes a numerical value N1 relating to at least one of the driving state of the human-powered vehicle 10 and the state of the rider. For example, the numerical value N1 relates to at least one of the vehicle speed of the human-powered vehicle 10, the acceleration of the human-powered vehicle 10, the human-powered driving force input to the human-powered vehicle 10, the output of the drive unit 46, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear shift stage of the transmission 48, the pitch angle of the human-powered vehicle 10, the rotational speed C of the crankshaft 20, the slope of the road the human-powered vehicle 10 is traveling on, the current time, the driving time of the human-powered vehicle 10, the total distance traveled by the human-powered vehicle 10, and the heart rate of the rider. The first information may also include, in place of or in addition to the numerical value N1, information relating to at least one of the lock state of the suspension 44, a plurality of control modes for the drive unit 46, the control state of the transmission 48, the remaining charge of the battery 40, and the illumination of the lamp 42.

[0073] For example, the control unit 72 is configured to select one of a plurality of control modes for the drive unit 46 depending on at least one of the driving state and driving environment of the human-powered vehicle 10. The plurality of control modes for the drive unit 46 relate, for example, to the ratio of the output of the motor 46A to the human-powered driving force.

[0074] For example, the display screen 52B is configured to display at least one image P. In this embodiment, at least one of the at least one image P corresponds to first information. For example, at least one image P includes at least one of characters, icons, and graphs. For example, at least one image P includes multiple images P. For example, the multiple images P include at least one of the following: image P1 relating to the current time, image P2 relating to the illumination status of the lamp 42, image P3 relating to the remaining battery level of the battery 40, image P4 relating to the rider's heart rate, image P5 relating to the vehicle speed of the human-powered vehicle 10, image P6 relating to the control mode and output of the drive unit 46, image P7 relating to the control state of the transmission 48, image P8 relating to the shifting stage of the transmission 48, and image P9 relating to the total distance traveled by the human-powered vehicle 10. In this embodiment, images P1, P2, P3, P4, P5, P6, P7, P8, and P9 each correspond to first information.

[0075] For example, as shown in Figure 3, display screen 52B displays images P1, P2, P3, P4, P5, P6, P7, P8, and P9. For example, the display state of display screen 52B shown in Figure 3 is the display state of display screen 52B in the reference state.

[0076] For example, the display screen 52B includes at least one part Q on which the first information is displayed. For example, the at least one part Q includes multiple parts Q. For example, the multiple parts Q include a first part Q1, a second part Q2, a third part Q3, a fourth part Q4, a fifth part Q5, a sixth part Q6, a seventh part Q7, an eighth part Q8, and a ninth part Q9. For example, the first part Q1 displays image P1. For example, the second part Q2 displays image P2. For example, the third part Q3 displays image P3. For example, the fourth part Q4 displays image P4.

[0077] For example, in section Q5, image P5 is displayed. For example, in section Q6, at least one image of P6 is displayed. For example, in section Q7, image P7 is displayed. For example, in section Q8, image P8 is displayed. For example, in section Q9, image P9 is displayed.

[0078] The control unit 72 is configured to cause the notification unit 52 to change the notification state in accordance with the amount of change per unit time of a first parameter relating to the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and at least one of the riders of the human-powered vehicle 10. For example, the control method for the notification device 50 for a human-powered vehicle includes the step of causing the notification device 50 to change the notification state in accordance with the amount of change per unit time of a first parameter relating to the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and at least one of the riders of the human-powered vehicle 10.

[0079] For example, the first parameter is detected by at least one of the following: the human-powered driving force detection unit 54, the crank rotation state detection unit 56, the vehicle speed detection unit 58, the gear shift state detection unit 60, the saddle load detection unit 62, the suspension operation state detection unit 64, and the tilt angle detection unit 66. For example, the control unit 72 is configured to control the notification unit 52 in accordance with the output of at least one of the human-powered driving force detection unit 54, the crank rotation state detection unit 56, the vehicle speed detection unit 58, the gear shift state detection unit 60, the saddle load detection unit 62, the suspension operation state detection unit 64, and the tilt angle detection unit 66.

[0080] For example, the notification state includes the display state of the display screen 52B of the display unit 52A. For example, the control unit 72 is configured to cause the display unit 52A to change the display state in accordance with the amount of change per unit time of a first parameter relating to the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and at least one of the riders of the human-powered vehicle 10.

[0081] For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B in which the first information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B in which the first information is displayed. The control unit 72 may also be configured to cause the notification unit 52 to change the notification state by hiding at least one of the first information displayed on the display screen 52B and displaying other information in the portion Q corresponding to the hidden first information.

[0082] For example, the unit time can be set arbitrarily. For example, the unit time includes at least one of the following: the first hour, the time it takes for the crankshaft 20 to rotate by the first rotation angle, and the time it takes for the wheel 12 to rotate by the second rotation angle. For example, the first hour is between 1 second and 6 seconds. For example, the first hour is between 3 seconds and 5 seconds. For example, the first rotation angle is between 360° and 3600°. For example, the second rotation angle is between 360° and 1800°.

[0083] For example, the first parameter includes at least one of the following: the vehicle speed of the human-powered vehicle 10, the acceleration of the human-powered vehicle 10, the human-powered driving force input to the human-powered vehicle 10, the output of the drive unit 46 that provides propulsion to the human-powered vehicle 10, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear shift stage of the transmission 48, the pitch angle of the human-powered vehicle 10, the rotational speed C of the crankshaft 20, the gradient of the road on which the human-powered vehicle 10 travels, and the rider's heart rate.

[0084] For example, the first parameter may include a numerical value relating to at least one of the following: the vehicle speed of the human-powered vehicle 10, the acceleration of the human-powered vehicle 10, the human-powered driving force input to the human-powered vehicle 10, the output of the drive unit 46 that provides propulsion to the human-powered vehicle 10, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear shift stage of the transmission 48, the pitch angle of the human-powered vehicle 10, the rotational speed C of the crankshaft 20, the gradient of the road on which the human-powered vehicle 10 travels, and the rider's heart rate.

[0085] For example, if the rate of change of the first parameter per unit time is greater than or equal to a first threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state. For example, if the rate of change of the first parameter per unit time is greater than or equal to a first threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B in which the first information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B in which the first information is displayed.

[0086] In this embodiment, if the amount of change of the first parameter per unit time is greater than or equal to a first threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q of the display screen 52B where the first information is displayed.

[0087] For example, the size of each of the images P1, P2, P3, P4, P5, P6, P7, P8, and P9 increases or decreases in conjunction with the increase or decrease in the area of ​​each of the first part Q1 to the ninth part Q9. For example, the display unit 52A increases or decreases the area of ​​one of the first part Q1 to the ninth part Q9 in response to an increase or decrease in the area of ​​one of the first part Q1 to the ninth part Q9. For example, the display unit 52A may prevent one of the first part Q1 to the ninth part Q9 from being displayed on the display screen 52B in response to an increase in the area of ​​one of the first part Q1 to the ninth part Q9.

[0088] For example, the control unit 72 is configured to control the notification unit 52 to return its notification state to the state it was in before the change once a predetermined condition is met, after the notification unit 52 has changed its notification state. For example, the predetermined condition is met after a predetermined period of time has elapsed.

[0089] For example, the predetermined period can be set arbitrarily. For example, the predetermined period includes at least one of the following: a second time, a period during which the crankshaft 20 rotates by a third rotation angle, and a period during which the wheel 12 rotates by a fourth rotation angle. For example, the second time is between 2 seconds and 10 seconds. For example, the second time is between 4 seconds and 8 seconds. For example, the third rotation angle is between 360° and 3600°. For example, the fourth rotation angle is between 360° and 1800°.

[0090] Referring to Figures 3 to 5, the process by which the control unit 72 changes the notification state of the notification unit 52 will be explained. For example, when power is supplied to the control unit 72, the control unit 72 starts processing and proceeds to step S11 of the flowchart shown in Figure 4. When the flowchart in Figure 4 is completed, the control unit 72 repeats the process from step S11 in Figure 4 at predetermined intervals, for example, until the power supply is stopped.

[0091] In step S11, the control unit 72 determines whether the rate of change of the first parameter per unit time is greater than or equal to a first threshold. If the rate of change of the first parameter per unit time is greater than or equal to the first threshold, the control unit 72 proceeds to step S12. For example, if the rate of change of the first parameter per unit time is greater than or equal to the first threshold, this includes cases where the motion state of the human-powered vehicle 10 changes significantly. For example, if the rate of change of the first parameter per unit time is less than the first threshold, the control unit 72 terminates the process.

[0092] In step S12, the control unit 72 controls the notification unit 52 to change its notification state. After controlling the notification unit 52 to change its notification state in step S12, the control unit 72 proceeds to step S13.

[0093] In step S13, the control unit 72 determines whether a predetermined condition is met. For example, the predetermined condition may be met when a second time has elapsed. The predetermined condition may also be met when a period of time has elapsed during which the crankshaft 20 has rotated by a third rotation angle. The predetermined condition may also be met when a period of time has elapsed during which the wheel 12 has rotated by a fourth rotation angle. If the predetermined condition is not met, the control unit 72 repeats the process in step S13. If the predetermined condition is met, the control unit 72 proceeds to step S14.

[0094] In step S14, the control unit 72 controls the notification unit 52 to return it to the notification state before the change in the notification state of the notification unit 52, and then terminates the process. For example, in step S14, the control unit 72 controls the notification unit 52 so that the display screen 52B becomes the display screen 52B of the reference state.

[0095] In step S12 of Figure 4, the control unit 72 controls the notification unit 52 to change the notification state of the notification unit 52 by increasing the area of ​​at least one portion Q of the display screen 52B on which the first information is displayed, and if the first information includes a gear shifting stage of the transmission 48, the area of ​​the eighth portion Q8 is larger than the reference state in Figure 3, as shown in Figure 5.

[0096] For example, the control unit 72 reduces the area of ​​at least one of the parts Q other than the eighth part Q8 by the process in step S12 of Figure 4. For example, in Figure 5, the area of ​​the fifth part Q5 is smaller than the area of ​​the fifth part Q5 in the reference state.

[0097] For example, a lidar can determine, by a change in the notification state, that the rate of change of the first parameter per unit time is greater than or equal to a first threshold. For example, when the rate of change of the first parameter per unit time is greater than or equal to a first threshold, the lidar can more easily grasp the first information corresponding to the portion Q whose area is increasing, and thus can perform lidar operations according to the first information.

[0098] For example, if the control unit 72 is configured to cause the notification unit 52 to change the notification state by reducing the area of ​​the portion Q on the display screen 52B where the first information is displayed, and the first information includes the gear shifting stage of the transmission 48, the area of ​​the eighth portion Q8 is reduced by the process in step S12 of Figure 4.

[0099] For example, if the control unit 72 is configured to cause the notification unit 52 to change the notification state by flashing at least a portion of the display screen 52B, and the first information includes a gear shift stage of the transmission 48, then the process in step S12 of Figure 4 causes at least a portion of the image P8 to flash.

[0100] For example, if the control unit 72 is configured to cause the notification unit 52 to change the notification state by changing the color of at least a portion of the display screen 52B, and the first information includes a gear shift stage of the transmission 48, then the processing in step S12 of Figure 4 changes the color of at least a portion of the eighth portion Q8.

[0101] For example, if the control unit 72 is configured to cause the notification unit 52 to change the notification state by changing the position of the portion Q on the display screen 52B in which the first information is displayed, and the first information includes a gear shift stage of the transmission 48, then the position of the eighth portion Q8 is swapped with the position of a portion Q other than the eighth portion Q8 by the process in step S12 of Figure 4.

[0102] <Second Embodiment> The control method for the control device 70 and notification device 50 of the second embodiment will be described with reference to Figures 2, 3, 5, and 6. The control method for the control device 70 and notification device 50 of the second embodiment includes the same configuration as the control method for the control device 70 and notification device 50 of the first embodiment, except that the process in Figure 6 is performed instead of the process in Figure 4. Therefore, for the components of the control method for the control device 70 and notification device 50 of the second embodiment that are common with the first embodiment, the same reference numerals are used as in the first embodiment, and redundant explanations are omitted.

[0103] For example, the control method for the notification device 50 for a human-powered vehicle of the second embodiment includes a step of causing the notification device 50 to change the notification state when a second parameter relating to at least one of the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10 changes from below a second threshold to above the second threshold, and changes from above a third threshold to below the third threshold, at least one of these cases.

[0104] In the second embodiment, the control unit 72 is configured to cause the notification unit 52 to change the notification state when a second parameter relating to at least one of the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10 changes from less than a second threshold to greater than or equal to the second threshold, and changes from greater than or equal to a third threshold to less than the third threshold. For example, the third threshold is less than or equal to the second threshold. For example, the third threshold may be greater than the second threshold.

[0105] For example, the control unit 72 is configured to cause the display unit 52A to change the display state of the display screen 52B in at least one of the following cases: when a second parameter relating to the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10 changes from below a second threshold to above the second threshold, and when it changes from above a third threshold to below the third threshold.

[0106] In the second embodiment, the second parameter includes at least one of the human-powered driving force input to the human-powered vehicle 10, the output of the drive unit 46 that imparts propulsion to the human-powered vehicle 10, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear shifting stage of the transmission 48, the pitch angle of the human-powered vehicle 10, the rotational speed C of the crankshaft 20, the gradient of the road on which the human-powered vehicle 10 travels, and the rider's heart rate.

[0107] For example, in at least one of the cases where the second parameter changes from below the second threshold to above the second threshold, and from above the third threshold to below the third threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing the area of ​​the portion Q of the display screen 52B where the first information is displayed. For example, at least one of the cases where the second parameter changes from below the second threshold to above the second threshold, and from above the third threshold to below the third threshold, includes cases where the motion state of the human-powered vehicle 10 changes significantly.

[0108] For example, in at least one of the cases where the second parameter changes from below the second threshold to above the second threshold, and from above the third threshold to below the third threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the first information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B where the first information is displayed.

[0109] For example, in at least one of the cases where the second parameter changes from below the second threshold to above the second threshold, and changes from above the third threshold to below the third threshold, the control unit 72 may be configured to cause the notification unit 52 to change the notification state by hiding at least one of the first pieces of information displayed on the display screen 52B and displaying other information in the part Q corresponding to the hidden first piece of information.

[0110] Referring to Figure 6, the process by which the control unit 72 changes the notification state of the notification unit 52 in the second embodiment will be described. For example, when power is supplied to the control unit 72, the control unit 72 starts processing and proceeds to step S21 of the flowchart shown in Figure 6. When the flowchart in Figure 6 is completed, the control unit 72 repeats the processing from step S21 of Figure 6 at predetermined intervals, for example, until the power supply is stopped.

[0111] In step S21, the control unit 72 determines whether the second parameter changes from below the second threshold to above the second threshold, or changes from above the third threshold to below the third threshold, or at least one of these two cases. For example, if the second parameter changes from below the second threshold to above the second threshold, the control unit 72 proceeds to step S22. For example, if the second parameter changes from above the third threshold to below the third threshold, the control unit 72 proceeds to step S22. For example, if the second parameter does not change from below the second threshold to above the second threshold, and does not change from above the third threshold to below the third threshold, the control unit 72 terminates the process.

[0112] In step S22, the control unit 72 controls the notification unit 52 to change its notification state and then proceeds to step S23. For example, in step S22, the control unit 72 controls the notification unit 52 to change its notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the first information is displayed.

[0113] In step S23, the control unit 72 determines whether a predetermined condition is met. For example, the predetermined condition may be met when a second time has elapsed. The predetermined condition may also be met when a period of time has elapsed during which the crankshaft 20 has rotated by a third rotation angle. The predetermined condition may also be met when a period of time has elapsed during which the wheel 12 has rotated by a fourth rotation angle. If the predetermined condition is not met, the control unit 72 repeats the process in step S23. If the predetermined condition is met, the control unit 72 proceeds to step S24.

[0114] In step S24, the control unit 72 controls the notification unit 52 to return it to the notification state before the change in the notification state of the notification unit 52, and then terminates the process. For example, in step S24, the control unit 72 controls the notification unit 52 so that the display screen 52B becomes the display screen 52B of the reference state.

[0115] The control unit 72 may, in step S21, determine only whether the second parameter changes from below the second threshold to above the second threshold. If the control unit 72 determines in step S21 only whether the second parameter changes from below the second threshold to above the second threshold, it proceeds to step S22 if the second parameter changes from below the second threshold to above the second threshold, and terminates the process if the second parameter does not change from below the second threshold to above the second threshold.

[0116] For example, in step S21, the control unit 72 may determine only whether the second parameter changes from above the third threshold to below the third threshold. If the control unit 72 determines only whether the second parameter changes from above the third threshold to below the third threshold in step S21, and the second parameter changes from above the third threshold to below the third threshold, the process proceeds to step S22. If the second parameter does not change from above the third threshold to below the third threshold, the process ends.

[0117] <Third Embodiment> The control method for the control device 70 and notification device 50 of the third embodiment will be described with reference to Figures 2, 3, 5, and 7. The control method for the control device 70 and notification device 50 of the third embodiment includes the same configuration as the control method for the control device 70 and notification device 50 of the first embodiment, except that the process in Figure 7 is performed instead of the process in Figure 4. Therefore, for the components of the control method for the control device 70 and notification device 50 of the third embodiment that are common with the first embodiment, the same reference numerals are used as in the first embodiment, and redundant explanations are omitted.

[0118] For example, the control method for the notification device 50 for a human-powered vehicle of the third embodiment includes the step of causing the notification unit 52 to change the notification state according to a control mode selected from a plurality of control modes relating to a drive unit 46 configured to impart propulsion to the human-powered vehicle 10.

[0119] In the third embodiment, the control unit 72 is configured to cause the notification unit 52 to change the notification state according to a control mode selected from a plurality of control modes relating to the drive unit 46 configured to impart propulsion to the human-powered vehicle 10. The notification unit 52 is configured to notify the rider of second information relating to the human-powered vehicle 10, the driving environment of the human-powered vehicle 10, and at least one of the rider of the human-powered vehicle 10, and which is not related to the control mode.

[0120] For example, the second information includes a numerical value N2 relating to at least one of the driving state of the human-powered vehicle 10 and the state of the rider. For example, the numerical value N2 relates to at least one of the following: the vehicle speed of the human-powered vehicle 10, the acceleration of the human-powered vehicle 10, the human-powered driving force input to the human-powered vehicle 10, the output of the drive unit 46, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear shift stage of the transmission 48, the pitch angle of the human-powered vehicle 10, the rotational speed C of the crankshaft 20, the gradient of the road the human-powered vehicle 10 is traveling on, the current time, the driving time of the human-powered vehicle 10, the total distance traveled by the human-powered vehicle 10, and the heart rate of the rider.

[0121] The second information may include, in place of or in addition to the numerical value N2, information regarding the lock state of the suspension 44, a plurality of control modes for the drive unit 46, the control state of the transmission 48, the remaining charge of the battery 40, and at least one of the illumination status of the lamp 42.

[0122] In the third embodiment, at least one image P of the first embodiment corresponds to second information instead of first information. For example, the at least one image P relating to the second information includes multiple images P. For example, the multiple images P relating to the second information include at least one of images P1, P2, P3, P4, P5, P7, P8, and P9.

[0123] For example, in the third embodiment, the display unit 52A is configured to display the second information on the display screen 52B. In the third embodiment, at least one portion Q of the display screen 52B displays the second information instead of the first information. For example, at least one portion Q includes multiple portions Q. For example, the multiple portions Q include a first portion Q1, a second portion Q2, a third portion Q3, a fourth portion Q4, a fifth portion Q5, a seventh portion Q7, an eighth portion Q8, and a ninth portion Q9.

[0124] For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the second information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B where the second information is displayed.

[0125] For example, when the control mode is changed, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the second information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B where the second information is displayed. For example, when the control mode is changed, the control unit 72 is configured to cause the notification unit 52 to change the notification state by hiding at least one of the second information displayed on the display screen 52B and displaying other information in the portion Q corresponding to the hidden second information.

[0126] In the third embodiment, the control unit 72 is configured to cause the notification unit 52 to change the notification state regarding the second information when the control mode is changed. For example, the control unit 72 is configured to cause the display unit 52A to change the display state of the display screen 52B when the control mode is changed. For example, the control unit 72 may be configured to cause the notification unit 52 to change the notification state regarding the second information when the control mode is changed from one of the multiple control modes to a specific control mode among the multiple control modes.

[0127] For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the second information is displayed. For example, when the control mode is changed, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the second information is displayed.

[0128] Referring to Figure 7, the process by which the control unit 72 changes the notification state of the notification unit 52 in the third embodiment will be described. For example, when power is supplied to the control unit 72, the control unit 72 starts processing and proceeds to step S31 of the flowchart shown in Figure 7. When the flowchart in Figure 7 is completed, the control unit 72 repeats the processing from step S31 in Figure 7 at predetermined intervals, for example, until the power supply is stopped.

[0129] In step S31, the control unit 72 determines whether the control mode has been changed. If the control mode has been changed, the control unit 72 proceeds to step S32. For example, if in step S31 the control mode is changed from one of the multiple control modes to a specific control mode among the multiple control modes, the control unit 72 may proceed to step S32. For example, if the control mode is not changed, the control unit 72 terminates the process.

[0130] In step S32, the control unit 72 controls the notification unit 52 to change its notification state and then proceeds to step S33. For example, in step S32, the control unit 72 controls the notification unit 52 to change its notification state by increasing or decreasing the area of ​​the portion Q of the display screen 52B where the second information is displayed.

[0131] In step S33, the control unit 72 determines whether a predetermined condition is met. For example, the predetermined condition may be met when a second time has elapsed. The predetermined condition may also be met when a period of time has elapsed during which the crankshaft 20 has rotated by a third rotation angle. The predetermined condition may also be met when a period of time has elapsed during which the wheel 12 has rotated by a fourth rotation angle. If the predetermined condition is not met, the control unit 72 repeats the process in step S33. If the predetermined condition is met, the control unit 72 proceeds to step S34.

[0132] In step S34, the control unit 72 controls the notification unit 52 to return it to the notification state before the change in the notification state of the notification unit 52, and then terminates the process. For example, in step S34, the control unit 72 controls the notification unit 52 so that the display screen 52B becomes the display screen 52B of the reference state.

[0133] <Fourth Embodiment> The control method for the control device 70 and notification device 50 of the fourth embodiment will be described with reference to Figures 2, 3, 5, and 8. The control method for the control device 70 and notification device 50 of the fourth embodiment includes the same configuration as the control method for the control device 70 and notification device 50 of the first embodiment, except that the process in Figure 8 is performed instead of the process in Figure 4. Therefore, for the components of the control method for the control device 70 and notification device 50 of the third embodiment that are common with the first embodiment, the same reference numerals are used as in the first embodiment, and redundant explanations are omitted.

[0134] For example, the control method for the notification device 50 for a human-powered vehicle of the fourth embodiment includes the step of causing the notification unit 52 to change the notification state according to the rider's state. The rider's state includes at least one of standing pedaling, sitting pedaling, and the rider's heart rate.

[0135] In the fourth embodiment, the notification unit 52 is configured to notify the rider of third information relating to the human-powered vehicle 10 and at least one of the driving environment of the human-powered vehicle 10, and which is not related to the rider's state. For example, the third information includes a numerical value N3 relating to the driving state of the human-powered vehicle 10.

[0136] For example, the numerical value N3 relates to at least one of the following: the vehicle speed of the human-powered vehicle 10, the acceleration of the human-powered vehicle 10, the human-powered driving force input to the human-powered vehicle 10, the output of the drive unit 46, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear shifting stage of the transmission 48, the pitch angle of the human-powered vehicle 10, the rotational speed C of the crankshaft 20, the gradient of the road the human-powered vehicle 10 is traveling on, the current time, the travel time of the human-powered vehicle 10, and the total distance traveled by the human-powered vehicle 10. The third information may include, in place of or in addition to the numerical value N3, information relating to at least one of the following: the lock state of the suspension 44, a plurality of control modes for the drive unit 46, the control state of the transmission 48, the remaining charge of the battery 40, and the illumination of the lamp 42.

[0137] In the fourth embodiment, at least one image P of the first embodiment corresponds to third information instead of first information. For example, the at least one image P relating to the third information includes multiple images P. For example, the multiple images P relating to the third information include at least one of images P1, P2, P3, P5, P6, P7, P8, and P9.

[0138] For example, the display unit 52A is configured to display the third information on the display screen 52B. In the fourth embodiment, at least one portion Q of the display screen 52B displays the third information instead of the first information. For example, at least one portion Q includes multiple portions Q. For example, the multiple portions Q include a first portion Q1, a second portion Q2, a third portion Q3, a fifth portion Q5, a sixth portion Q6, a seventh portion Q7, an eighth portion Q8, and a ninth portion Q9.

[0139] For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the third information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B where the third information is displayed.

[0140] For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state regarding the third information according to the state of the Writer. For example, the control unit 72 is configured to cause the display unit 52A to change the display state of the display screen 52B according to the state of the Writer. For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state according to the state of the Writer by increasing or decreasing the area of ​​the portion Q on the display screen 52B in which the third information is displayed, blinking at least a portion of the display screen 52B, changing the color of at least a portion of the display screen 52B, and changing the position of the portion Q on the display screen 52B in which the third information is displayed.

[0141] For example, the control unit 72 is configured to change the notification state regarding the third information to the notification unit 52 when the state of the rider changes. For example, the control unit 72 may be configured to change the notification state regarding the third information to the notification unit 52 in response to switching between standing and sitting pedaling.

[0142] For example, the control unit 72 may be configured to change the notification state for the third information to the notification unit 52 in response to a change in the rider's heart rate. For example, the control unit 72 may be configured to change the notification state for the third information to the notification unit 52 when the rider's heart rate is above the fourth threshold. For example, the control unit 72 may be configured to change the notification state for the third information to the notification unit 52 when the rider's heart rate changes from below the fifth threshold to above the fifth threshold. For example, the control unit 72 may be configured to change the notification state for the third information to the notification unit 52 when the rider's heart rate changes from above the sixth threshold to below the sixth threshold. For example, the fifth threshold may be above the sixth threshold or below the sixth threshold.

[0143] For example, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the third information is displayed. For example, depending on the state of the lighter, the control unit 72 is configured to cause the notification unit 52 to change the notification state by increasing or decreasing the area of ​​the portion Q on the display screen 52B where the third information is displayed.

[0144] Referring to Figure 8, the process by which the control unit 72 changes the notification state of the notification unit 52 in the fourth embodiment will be described. For example, when power is supplied to the control unit 72, the control unit 72 starts processing and proceeds to step S41 of the flowchart shown in Figure 8. When the flowchart in Figure 8 ends, the control unit 72 repeats the processing from step S41 in Figure 8 at predetermined intervals, for example, until the power supply is stopped.

[0145] In step S41, the control unit 72 determines whether the rider's state has changed. If the rider's state has changed, the control unit 72 proceeds to step S42. For example, the control unit 72 determines that the rider's state has changed if the rider switches between standing and sitting, if the rider's heart rate is above the fourth threshold, if the rider's heart rate changes from below the fifth threshold to above the fifth threshold, or if the rider's heart rate changes from above the sixth threshold to below the sixth threshold. If the rider's state has changed, the control unit 72 proceeds to step S42. For example, if the rider's state has not changed, the control unit 72 terminates the process.

[0146] In step S42, the control unit 72 controls the notification unit 52 to change its notification state and then proceeds to step S43. For example, in step S42, the control unit 72 controls the notification unit 52 to change its notification state by increasing or decreasing the area of ​​the portion Q of the display screen 52B where the third information is displayed.

[0147] In step S43, the control unit 72 determines whether a predetermined condition is met. For example, the predetermined condition may be met when a second time has elapsed. The predetermined condition may also be met when a period of time has elapsed during which the crankshaft 20 has rotated by a third rotation angle. The predetermined condition may also be met when a period of time has elapsed during which the wheel 12 has rotated by a fourth rotation angle. If the predetermined condition is not met, the control unit 72 repeats the process in step S43. If the predetermined condition is met, the control unit 72 proceeds to step S44.

[0148] In step S44, the control unit 72 controls the notification unit 52 to return it to the notification state before the change in the notification state of the notification unit 52, and then terminates the process. For example, in step S44, the control unit 72 controls the notification unit 52 so that the display screen 52B becomes the display screen 52B of the reference state.

[0149] <Example of changes> The descriptions of each embodiment are illustrative of possible forms of control methods for control devices and notification devices for human-powered vehicles according to this disclosure, and are not intended to limit their forms.

In the following modifications, parts common to each embodiment are denoted by the same reference numerals as in each embodiment, and their descriptions are omitted.

[0150] For example, the notification unit 52 may include a speaker in place of or in addition to the display unit 52A. For example, the speaker notifies at least one of the first information, the second information, and the third information by sound. The sound output from the speaker includes voice, melody, and beeps. For example, the control unit 72 causes the notification unit 52 to change the notification state by changing the sound output from the speaker.
