[0055] When at least one of the running state of the human-powered vehicle 10 and the running environment of the human-powered vehicle 10 includes a gradient S of the road on which the human-powered vehicle 10 is running, the human-powered vehicle 10 preferably includes a gradient detection unit 58. The gradient detection unit 58 includes, for example, at least one of an inclination sensor and a GPS receiver.

[0056] The inclination sensor is configured to detect the gradient S of the road on which the human-powered vehicle 10 is traveling. The gradient S corresponds to the tilt angle in the traveling direction of the human-powered vehicle 10. The gradient S corresponds to the pitch angle of the human-powered vehicle 10. The inclination sensor includes, for example, at least one of a gyro sensor and an acceleration sensor. The inclination sensor is connected to the control unit 62 via a wireless communication device or an electric cable.

[0057] When the gradient detection unit 58 includes a GPS receiver, the control unit 62 may calculate the gradient S according to GPS information acquired by the GPS receiver and information on the road surface gradient included in map information pre-recorded in the storage unit 64. The inclination sensor may include a GPS receiver.

[0058] When the gradient detection unit 58 includes at least one of an inclination sensor and a GPS receiver, the control unit 62 calculates the amount of change in the gradient S according to the output of at least one of the inclination sensor and the GPS receiver. For example, the control unit 62 calculates the amount of change in the gradient S per unit time as the amount of change in the gradient S.

[0059] Preferably, the value related to information A is the cadence of the human-powered vehicle 10. Preferably, the control unit 62 calculates the cadence from the amount of rotation of the wheel 12 detected by the detection unit 54 and the gear ratio of the human-powered vehicle 10. The control unit 62 calculates the cadence by dividing the amount of rotation of the wheel 12 per predetermined period by the gear ratio. The predetermined period is, for example, the period in which the wheel 12 rotates 360 degrees.

[0060] The first value is calculated according to the information A in the first period. Preferably, the first period is a period during which the rotating body 52 rotates a first rotation amount. Preferably, the first period is a period until the signal SR is detected a first predetermined number of times. The first predetermined number of times is, for example, 1 time. The first period is, for example, a value obtained by dividing 1 by the number P of N poles or S poles of the power generation device 42. The first period is, for example, a period during which the rotating body 52 rotates 1 / P. The period during which the rotating body 52 rotates 1 / P is a period during which the rotating body 52 rotates 360 / P degrees. When the number P of N poles or S poles of the power generation device 42 is 16, for example, the first period is a period during which the rotating body 52 rotates 1 / 16. When the number P of N poles or S poles of the power generation device 42 is 16, for example, the first period is a period during which the rotating body 52 rotates 22.5 degrees.

[0061] Preferably, the first value is calculated according to the first rotation amount and the time required for the rotating body 52 to rotate through the first rotation amount. Preferably, the first value is the cadence of the human-powered vehicle 10. When the first value is the cadence, for example, the control unit 62 calculates the first value by multiplying the time required for the wheel 12 to rotate 1 / P by P, and dividing the reciprocal of the value by the gear ratio. The unit of the time required for the wheel 12 to rotate 1 / P is, for example, minutes. The first value is calculated, for example, by Equation 2. (Formula 2):C1=(1 / T1*P) / R C1 indicates a first value. The unit of the first value is rpm. T1 indicates the time it takes for the wheel 12 to rotate by 1 / P. P indicates the number of north or south poles of the power generating device 42. R indicates the gear ratio.

[0062] Preferably, the second period is a period during which the rotor 52 rotates a second amount of rotation that is greater than the first amount of rotation. Preferably, the second period is a period until the signal SR is detected a second predetermined number of times that is greater than the first predetermined number of times. Preferably, the second period is a period during which the rotor 52 rotates once. If the number of north poles or south poles of the power generating device 42 is 16, for example, the second period is a period during which the signal SR is detected 16 times. If the number P of north poles or south poles of the power generating device 42 is 16, for example, the first period is a period during which the rotor 52 rotates 360 degrees.

[0063] Preferably, the second value is calculated according to the information A in a second period longer than the first period. Preferably, the second value is calculated according to the second rotation amount and the time required for the rotating body 52 to rotate through the second rotation amount. Preferably, the second value is the cadence of the human-powered vehicle 10. When the second value is the cadence, for example, the control unit 62 calculates the second value by dividing the reciprocal of the time required for the wheel 12 to rotate once by the gear ratio. The unit of the time required for the wheel 12 to rotate once is, for example, minutes. The second value is calculated, for example, by Equation 3. (Formula 3):C2=(1 / T2) / R C2 indicates a second value. The unit of the second value is rpm. T2 indicates the time it takes for the wheel 12 to rotate once. R indicates the gear ratio.

[0064] Preferably, the control unit 62 controls the transmission 48 to change the gear ratio of the human-powered vehicle 10 when the value related to the information A is outside a predetermined range. For example, when the cadence of the human-powered vehicle 10 is outside a predetermined range, the control unit 62 controls the transmission 48 to change the gear ratio of the human-powered vehicle 10. Preferably, the control unit 62 controls the transmission 48 to increase the gear ratio when the cadence becomes larger than the predetermined range. Preferably, the control unit 62 controls the transmission 48 to decrease the gear ratio when the cadence becomes smaller than the predetermined range.

[0065] The process of controlling the transmission 48 executed by the control unit 62 will be described with reference to Fig. 3. When power is supplied to the control unit 62, the control unit 62 starts the process and proceeds to step S11 of the flowchart shown in Fig. 3. When the flowchart of Fig. 3 ends, the control unit 62 repeats the process from step S11 after a predetermined period until the supply of power is stopped.

[0066] In step S11, the control unit 62 determines whether or not at least one of the running state of the human-powered vehicle 10 and the running environment of the human-powered vehicle 10 is in a first state. If in step S11, at least one of the running state of the human-powered vehicle 10 and the running environment of the human-powered vehicle 10 is in the first state, the control unit 62 proceeds to step S12. If in step S11, at least one of the running state of the human-powered vehicle 10 and the running environment of the human-powered vehicle 10 is not in the first state, the control unit 62 proceeds to step S13.

[0067] In step S12, the control unit 62 calculates a first value in accordance with information A relating to the rotational speed of the rotating body 52 of the human-powered vehicle 10 detected by the detection unit 54, and then proceeds to step S14.

[0068] In step S14, the control unit 62 determines whether the first value is greater than a predetermined range. If the first value is equal to or less than the predetermined range in step S14, the control unit 62 proceeds to step S15. If the first value is greater than the predetermined range, the control unit 62 proceeds to step S16.

[0069] In step S16, the control unit 62 controls the transmission 48 so that the gear ratio of the human-powered vehicle 10 becomes large, and then ends the process.

[0070] In step S15, the control unit 62 determines whether the first value is smaller than a predetermined range. If the first value is within the predetermined range in step S15, the control unit 62 ends the process. If the first value is smaller than the predetermined range, the control unit 62 proceeds to step S17.

[0071] In step S17, the control unit 62 controls the transmission 48 so that the gear ratio of the human-powered vehicle 10 becomes smaller, and then ends the process.

[0072] In step S13, the control unit 62 calculates a second value in accordance with information A relating to the rotational speed of the rotating body 52 of the human-powered vehicle 10 detected by the detection unit 54, and then the process proceeds to step S18.

[0073] In step S18, the control unit 62 determines whether the second value is greater than a predetermined range. If the second value is equal to or less than the predetermined range in step S18, the control unit 62 proceeds to step S19. If the second value is greater than the predetermined range, the control unit 62 proceeds to step S20.

[0074] In step S20, the control unit 62 controls the transmission 48 so that the gear ratio of the human-powered vehicle 10 becomes large, and then ends the process.

[0075] In step S19, the control unit 62 determines whether the second value is smaller than a predetermined range. If the second value is within the predetermined range in step S19, the control unit 62 ends the process. If the second value is smaller than the predetermined range, the control unit 62 proceeds to step S21.

[0076] In step S21, the control unit 62 controls the transmission 48 so that the gear ratio of the human-powered vehicle 10 becomes small, and then ends the process.

[0077] For example, when the human-powered vehicle 10 starts to climb a slope, the deceleration of the human-powered vehicle 10 is likely to reach or exceed a predetermined deceleration. In the first state, the control unit 62 controls the transmission 48 to change the gear ratio by the first value, so that the gear ratio can be changed early when the human-powered vehicle 10 starts to climb a slope.

[0078] For example, when the human-powered vehicle 10 is cruising on a flat road, the deceleration of the human-powered vehicle 10 is likely to be less than the predetermined deceleration. In the second state, the control unit 62 controls the transmission 48 to change the gear ratio according to the second value, so when the human-powered vehicle 10 is cruising on a flat road, it becomes difficult to change the gear ratio in response to an instantaneous change in the parameter. This makes it possible to reduce the frequency with which the gear ratio is changed.
