For example, the map information including information about the gradient of the road on which the human-powered vehicle 10 is traveling is stored in the memory unit 74.

[0069] For example, the tilt angle detection unit 66 is connected to the control unit 72 so that they can communicate with each other via wire or wirelessly.

[0072] For example, the first information includes a numerical value N1 related to at least one of the traveling 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 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 is traveling, the current time, the traveling time of the human-powered vehicle 10, the total traveling distance of the human-powered vehicle 10, and the heart rate of the rider.

[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 to, for example, 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 be able to display at least one image P. In this embodiment, at least one of the at least one image P corresponds to the first information. For example, the at least one image P includes at least one of text, an icon, and a graph. For example, the at least one image P includes a plurality of images P.

In this embodiment, the images P1, P2, P3, P4, P5, P6, P7, P8, and P9 each correspond to the first information.

[0075] For example, as shown in Fig. 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 Fig. 3 is the display state of display screen 52B in a reference state.

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

[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 related to at least one of the human-powered vehicle 10, the traveling environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10. For example, a control method for a 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 related to at least one of the human-powered vehicle 10, the traveling environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10.

[0079] For example, the first parameter is detected by at least one of the manual 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 lean 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 manual 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 lean 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 related to at least one of the human-powered vehicle 10, the traveling environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10.

[0081] For example, the control unit 72 is configured to cause the alarm unit 52 to change the alarm state by at least one of increasing or decreasing the area of ​​a portion Q of the display screen 52B where the first information is displayed, flashing 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 of the display screen 52B where the first information is displayed. The control unit 72 may also be configured to cause the alarm unit 52 to change the alarm state by hiding at least one piece of the first information displayed on the display screen 52B and displaying information other than the first 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 a first time, a time for the crankshaft 20 to rotate by a first rotation angle, and a time for the wheel 12 to rotate by a second rotation angle. For example, the first time is not less than 1 second and not more than 6 seconds. For example, the first time is not less than 3 seconds and not more than 5 seconds. For example, the first rotation angle is not less than 360° and not more than 3600°. For example, the second rotation angle is not less than 360° and not more than 1800°.

[0083] For example, the first parameter includes 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 that provides propulsion force to the human-powered vehicle 10, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear 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 is traveling, and the rider's heart rate.

[0084] For example, the first parameter may include numerical values ​​relating 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 that provides propulsion force to the human-powered vehicle 10, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear 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 is traveling, and the rider's heart rate.

[0085] For example, when the amount of change per unit time of the first parameter is equal to or greater than a first threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state. For example, when the amount of change per unit time of the first parameter is equal to or greater than the first threshold, the control unit 72 is configured to cause the notification unit 52 to change the notification state by at least one of increasing or decreasing the area of ​​a portion Q of 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 of the display screen 52B where the first information is displayed.

[0086] In this embodiment, when the change in the first parameter per unit time is equal to or greater than the first threshold value, 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 an increase or decrease in the area of ​​each of the first portion Q1 to the ninth portion Q9. For example, the display unit 52A increases or decreases the area of ​​another of the first portion Q1 to the ninth portion Q9 in response to an increase or decrease in the area of ​​one of the first portion Q1 to the ninth portion Q9. For example, the display unit 52A may prevent the other of the first portion Q1 to the ninth portion Q9 from being displayed on the display screen 52B in response to an increase in the area of ​​one of the first portion Q1 to the ninth portion Q9.

[0088] For example, the control unit 72 is configured to control the notification unit 52 so that, after changing the notification state of the notification unit 52, when a predetermined condition is satisfied, the notification state of the notification unit 52 is returned to the notification state before the change of the notification state. For example, the predetermined condition is satisfied when 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 second time, the period during which the crankshaft 20 rotates by a third rotation angle, and the period during which the wheel 12 rotates by a fourth rotation angle. For example, the second time is not less than 2 seconds and not more than 10 seconds. For example, the second time is not less than 4 seconds and not more than 8 seconds. For example, the third rotation angle is not less than 360° and not more than 3600°. For example, the fourth rotation angle is not less than 360° and not more than 1800°.

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

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

[0092] In step S12, the control unit 72 controls the notification unit 52 to change the notification state of the notification unit 52. After controlling the notification unit 52 to change the notification state of the notification unit 52 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 satisfied. For example, the predetermined condition is satisfied when a second time period has elapsed. The predetermined condition may also be satisfied when a period of time during which the crankshaft 20 rotates a third rotation angle has elapsed. The predetermined condition may also be satisfied when a period of time during which the wheel 12 rotates a fourth rotation angle has elapsed. If the predetermined condition is not satisfied, the control unit 72 repeats the process of step S13. If the predetermined condition is satisfied, the control unit 72 proceeds to step S14.

[0094] In step S14, the control unit 72 controls the notification unit 52 to return the notification state of the notification unit 52 to the notification state before the change, and ends 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 in the reference state.

[0095] In step S12 of FIG. 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 of the portions Q of the display screen 52B where the first information is displayed, and when the first information includes the shift stage of the transmission 48, as shown in FIG. 5, the area of ​​the eighth portion Q8 is larger than the reference state of FIG. 3.

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

[0097] For example, the change in the notification state allows the rider to know that the amount of change per unit time of the first parameter is equal to or greater than the first threshold. For example, when the amount of change per unit time of the first parameter is equal to or greater than the first threshold, the rider can easily understand the first information corresponding to the portion Q whose area increases, and can ride in accordance with the first information.

[0098] For example, when 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 of the display screen 52B where the first information is displayed, and when the first information includes the shift stage of the transmission 48, the control unit 72 reduces the area of ​​the eighth portion Q8 by processing step S12 in Figure 4.

[0099] For example, when 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 when the first information includes the shift stage of the transmission 48, the control unit 72 flashes at least a portion of the image P8 by processing step S12 in Figure 4.

[0100] For example, when 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 when the first information includes the shift stage of the transmission 48, the control unit 72 changes the color of at least a portion of the eighth portion Q8 by processing step S12 in Figure 4.

[0101] For example, when 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 where the first information is displayed, and when the first information includes the shift stage of the transmission 48, the control unit 72 processes step S12 in Figure 4 to swap the position of the eighth portion Q8 with the position of a portion Q other than the eighth portion Q8.

[0102] Second Embodiment A control method for the control device 70 and the alarm 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 the alarm device 50 of the second embodiment includes the same configuration as the control method for the control device 70 and the alarm device 50 of the first embodiment, except that the process of Figure 6 is executed instead of the process of Figure 4. Therefore, the configuration of the control device 70 and the control method for the alarm device 50 of the second embodiment that is common to the first embodiment is assigned the same reference numerals as in the first embodiment, and redundant description will be omitted.

[0103] For example, the control method of the alarm device 50 for a human-powered vehicle in the second embodiment includes a step of causing the alarm device 50 to change the alarm state in at least one of the cases where a second parameter related 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 the second threshold to greater than the second threshold, and where the second parameter changes from greater than the third threshold to less than the third threshold.

[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 related to at least one of the human-powered vehicle 10, the traveling environment of the human-powered vehicle 10, and the rider of the human-powered vehicle 10 changes from less than the second threshold to equal to or greater than the second threshold, or changes from equal to or greater than a third threshold to less than the third threshold. For example, the third threshold is equal to or less than 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 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 the second threshold to greater than the second threshold, and when the second parameter changes from greater than the third threshold to less than 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 provides propulsion force to the human-powered vehicle 10, the gear ratio R of the transmission 48 of the human-powered vehicle 10, the gear 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 is traveling, and the rider's heart rate.

[0107] For example, when the second parameter changes from less than the second threshold to equal to or greater than the second threshold, or when the second parameter changes from equal to or greater than the third threshold to less than the third threshold, the control unit 72 is configured to increase the area of ​​the portion Q of the display screen 52B where the first information is displayed, thereby causing the notification unit 52 to change the notification state. For example, when the second parameter changes from less than the second threshold to equal to or greater than the second threshold, or when the second parameter changes from equal to or greater than the third threshold to less than the third threshold, this includes a case where the motion state of the human-powered vehicle 10 changes significantly.

[0108] For example, when the second parameter changes from less than the second threshold to more than the second threshold, and when the second parameter changes from more than the third threshold to less than the third threshold, the control unit 72 is configured to cause the alarm unit 52 to change the alarm state by at least one of increasing or decreasing the area of ​​the portion Q of the display screen 52B where the first information is displayed, flashing 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 of the display screen 52B where the first information is displayed.

[0109] For example, when the second parameter changes from less than the second threshold to more than the second threshold, and at least when it changes from more than the third threshold to less than the third threshold, the control unit 72 may be configured to hide at least one of the first information displayed on the display screen 52B and to cause the alarm unit 52 to change the alarm state by displaying information other than the first information in the portion Q corresponding to the hidden first information.

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

[0111] In step S21, the control unit 72 determines whether the second parameter changes from less than the second threshold to equal to or greater than the second threshold, or from equal to or greater than the third threshold to less than the third threshold. For example, if the second parameter changes from less than the second threshold to equal to or greater than the second threshold, the control unit 72 proceeds to step S22. For example, if the second parameter changes from equal to or greater than the third threshold to less than the third threshold, the control unit 72 proceeds to step S22. For example, if the second parameter does not change from less than the second threshold to equal to or greater than the second threshold, or from equal to or greater than the third threshold to less than the third threshold, the control unit 72 ends the process.

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

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

[0114] In step S24, the control unit 72 controls the notification unit 52 to return the notification state of the notification unit 52 to the notification state before the change, and ends 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 in the reference state.

[0115] The control unit 72 may determine only whether the second parameter changes from less than the second threshold to equal to or greater than the second threshold in step S21. When the control unit 72 determines only whether the second parameter changes from less than the second threshold to equal to or greater than the second threshold in step S21, if the second parameter changes from less than the second threshold to equal to or greater than the second threshold, the control unit 72 proceeds to step S22, and if the second parameter does not change from less than the second threshold to equal to or greater than the second threshold, the control unit 72 ends the process.

[0116] For example, the control unit 72 may determine only whether the second parameter changes from equal to or greater than the third threshold to less than the third threshold in step S21. When the control unit 72 determines only whether the second parameter changes from equal to or greater than the third threshold to less than the third threshold in step S21, if the second parameter changes from equal to or greater than the third threshold to less than the third threshold, the control unit 72 proceeds to step S22, and if the second parameter does not change from equal to or greater than the third threshold to less than the third threshold, the control unit 72 ends the process.

[0117] <Third embodiment> A control method for the control device 70 and the alarm 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 the alarm device 50 of the third embodiment includes the same configuration as the control method for the control device 70 and the alarm device 50 of the first embodiment, except that the process of Figure 7 is executed instead of the process of Figure 4. Therefore, the configuration of the control device 70 and the control method for the alarm device 50 of the third embodiment that is common to the first embodiment is assigned the same reference numerals as in the first embodiment, and redundant description will be omitted.

[0118] For example, the control method of the alarm device 50 for a human-powered vehicle of the third embodiment includes a step of causing the alarm unit 52 to change the alarm state in accordance with a control mode selected from a plurality of control modes related to the drive unit 46 configured to provide propulsive force 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 in accordance with a control mode selected from a plurality of control modes related to the drive unit 46 configured to provide propulsive force to the human-powered vehicle 10. The notification unit 52 is configured to notify the rider of second information related to at least one of the human-powered vehicle 10, the traveling environment of the human-powered vehicle 10, and 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 and the state of the rider of the human-powered vehicle 10. For example, the numerical value N2 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 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 is traveling, the current time, the traveling 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, instead of or in addition to the numerical value N2, information regarding at least one of the lock status of the suspension 44, multiple control modes for the drive unit 46, the control status of the transmission 48, the remaining charge of the battery 40, and the illumination of the lamp 42.

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

[0123] For example, in the third embodiment, the display unit 52A is configured to display 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, the at least one portion Q includes a plurality of portions Q. For example, the plurality of 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 alarm unit 52 to change the alarm state by at least one of increasing or decreasing the area of ​​the portion Q of the display screen 52B where the second information is displayed, flashing 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 of the display screen 52B where the second information is displayed.

[0125] For example, when the control mode is changed, the control unit 72 ,table The control unit 72 is configured to cause the notification unit 52 to change the notification state by at least one of increasing or decreasing the area of ​​a portion Q of the display screen 52B where the second information is displayed, flashing 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 of 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 piece of the second information displayed on the display screen 52B and displaying information other than the second 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 plurality of control modes to a specific control mode among the plurality of 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 of 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 of the display screen 52B where the second information is displayed.

[0128] A process in which the control unit 72 changes the notification state of the notification unit 52 in the third embodiment will be described with reference to Fig. 7. For example, when power is supplied to the control unit 72, the control unit 72 starts the process and proceeds to step S31 of the flowchart shown in Fig. 7. When the flowchart in Fig. 7 ends, the control unit 72 repeats the process from step S31 in Fig. 7 at predetermined intervals, for example, until the supply of power 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 the control mode is changed from one of the multiple control modes to a specific control mode among the multiple control modes in step S31, the control unit 72 may proceed to step S32. For example, if the control mode is not changed, the control unit 72 ends the process.

[0130] In step S32, the control unit 72 controls the notification unit 52 to change the notification state of the notification unit 52, and then the process proceeds to step S33. For example, in step S32, the control unit 72 controls the notification unit 52 to change the notification state of the notification unit 52 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 satisfied. For example, the predetermined condition is satisfied when a second time period has elapsed. The predetermined condition may also be satisfied when a period of time during which the crankshaft 20 rotates a third rotation angle has elapsed. The predetermined condition may also be satisfied when a period of time during which the wheel 12 rotates a fourth rotation angle has elapsed. If the predetermined condition is not satisfied, the control unit 72 repeats the process of step S33. If the predetermined condition is satisfied, the control unit 72 proceeds to step S34.

[0132] In step S34, the control unit 72 controls the notification unit 52 to return the notification state of the notification unit 52 to the notification state before the change, and ends 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 in the reference state.

[0133] <Fourth embodiment> A control method for the control device 70 and the alarm 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 the alarm device 50 of the fourth embodiment includes the same configuration as the control method for the control device 70 and the alarm device 50 of the first embodiment, except that the process of Figure 8 is executed instead of the process of Figure 4. Therefore, the configuration of the control device 70 and the control method for the alarm device 50 of the third embodiment that is common to the first embodiment is assigned the same reference numerals as in the first embodiment, and redundant description will be omitted.

[0134] For example, the control method for the notification device 50 for a human-powered vehicle of the fourth embodiment includes a step of causing the notification unit 52 to change the notification state in accordance with the rider's state, which 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 that relates to at least one of the human-powered vehicle 10 and the traveling environment of the human-powered vehicle 10, and that is not related to the state of the rider of the human-powered vehicle 10. For example, the third information includes a numerical value N3 that relates to the traveling state of the human-powered vehicle 10.

[0136] For example, the numerical value N3 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 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 is traveling, the current time, the traveling time of the human-powered vehicle 10, and the total traveling distance of the human-powered vehicle 10. Instead of or in addition to the numerical value N3, the third information may include information relating to at least one of the lock state of the suspension 44, a plurality of control modes related to 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 in the first embodiment corresponds to third information instead of the first information. For example, the at least one image P related to the third information includes multiple images P. For example, the multiple images P related to the third information include at least one of image P1, image P2, image P3, image P5, image P6, image P7, image P8, and image P9.

[0138] For example, the display unit 52A is configured to display 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, the at least one portion Q includes a plurality of portions Q. For example, the plurality of 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 alarm unit 52 to change the alarm state by at least one of increasing or decreasing the area of ​​the portion Q of the display screen 52B where the third information is displayed, flashing 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 of the display screen 52B where the third information is displayed.

[0140] For example, the control unit 72 is configured to cause the notifying unit 52 to change the notification state regarding the third information in accordance with the rider's state. 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 accordance with the rider's state. For example, the control unit 72 is configured to cause the notifying unit 52 to change the notification state in accordance with the rider's state by at least one of increasing or decreasing the area of ​​a portion Q of the display screen 52B where the third information is displayed, flashing 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 of the display screen 52B where the third information is displayed.

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

[0142] For example, the control unit 72 may be configured to cause the alarm unit 52 to change the alert state regarding the third information in response to a change in the rider's heart rate. For example, the control unit 72 may be configured to cause the alarm unit 52 to change the alert state regarding the third information when the rider's heart rate is equal to or greater than a fourth threshold. For example, the control unit 72 may be configured to cause the alarm unit 52 to change the alert state regarding the third information when the rider's heart rate changes from less than a fifth threshold to equal to or greater than the fifth threshold. For example, the control unit 72 may be configured to cause the alarm unit 52 to change the alert state regarding the third information when the rider's heart rate changes from equal to or greater than a sixth threshold to less than the sixth threshold. For example, the fifth threshold may be equal to or greater than the sixth threshold or less than 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 of the display screen 52B where the third information is displayed. For example, depending on the rider's state, 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 third information is displayed.

[0144] Referring to Fig. 8, a process in 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 the process and proceeds to step S41 of the flowchart shown in Fig. 8. When the flowchart in Fig. 8 ends, the control unit 72 repeats the process from step S41 in Fig. 8 at predetermined intervals until, for example, the supply of power 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 pedaling, if the rider's heart rate is equal to or greater than the fourth threshold, if the rider's heart rate changes from less than the fifth threshold to equal to or greater than the fifth threshold, or if the rider's heart rate changes from equal to or greater than the sixth threshold to less than 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 ends the processing.

[0146] In step S42, the control unit 72 controls the notification unit 52 to change the notification state of the notification unit 52, and the process proceeds to step S43. For example, in step S42, the control unit 72 controls the notification unit 52 to change the notification state of the notification unit 52 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 satisfied. For example, the predetermined condition is satisfied when a second time period has elapsed. The predetermined condition may also be satisfied when a period of time during which the crankshaft 20 rotates a third rotation angle has elapsed. The predetermined condition may also be satisfied when a period of time during which the wheel 12 rotates a fourth rotation angle has elapsed. If the predetermined condition is not satisfied, the control unit 72 repeats the process of step S43. If the predetermined condition is satisfied, the control unit 72 proceeds to step S44.

[0148] In step S44, the control unit 72 controls the notification unit 52 to return the notification state of the notification unit 52 to the notification state before the change, and ends 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 in the reference state.
