[0037] The first control unit 52 is configured to control the motor 42 so that the assist level A provided by the motor 42 becomes a predetermined assist level AX. Preferably, the assist level A is for a human-powered vehicle. 10The system includes at least one of the following: the ratio of the motor 42's output to the human-powered driving force H input to the system, the maximum value MX of the motor 42's output, and the level L of suppression of the motor 42's output fluctuation when the motor 42's output decreases. The ratio of the assist force provided by the motor 42 to the human-powered driving force H may be referred to as the assist ratio.

[0038] The first control unit 52 is configured to control the motor 42 such that the assist force provided by the motor 42 is in a predetermined ratio to the human-powered driving force H. The human-powered driving force H corresponds to the propulsion force of the human-powered vehicle 10 generated by the user rotating the crank. The assist force corresponds to the propulsion force of the human-powered vehicle 10 generated by the rotation of the motor 42. The predetermined ratio is not constant and may change according to the human-powered driving force H, the rotational speed C of the crankshaft, the vehicle speed V, or any two or all of the human-powered driving force H, the rotational speed C of the crankshaft, and the vehicle speed V.

[0039] When the human-powered driving force H and the assist force are expressed in terms of torque, the human-powered driving force H is written as human-powered torque HT, and the assist force is written as assist torque MT. When the human-powered driving force H and the assist force are expressed in terms of power, the human-powered driving force H is written as human-powered power HW, and the assist force is written as assist power MW. The ratio may be the torque ratio of the assist torque MT to the human-powered torque HT of the human-powered vehicle 10, or it may be the ratio of the assist power MW from the motor 42 to the human-powered power HW.

[0040] In the drive unit 40 of this embodiment, the crank is connected to the first rotating body without a transmission, and the output of the motor 42 is input to the first rotating body. In this embodiment, the human-powered driving force H corresponds to the driving force input to the first rotating body by the user rotating the crank. In this embodiment, the assist force corresponds to the driving force input to the first rotating body by the rotation of the motor 42. If the output of the motor 42 is input to the first rotating body via a reduction gear, the assist force corresponds to the output of the reduction gear.

[0041] When a motor 42 is provided on the rear wheel, the human-powered driving force H corresponds to the output of the rear wheel driven solely by the user. When a motor 42 is provided on the rear wheel, the assist force corresponds to the output of the rear wheel driven solely by the motor 42. When a motor 42 is provided on the front wheel, the human-powered driving force H corresponds to the output of the rear wheel driven solely by the user. When a motor 42 is provided on the front wheel, the assist force corresponds to the output of the front wheel driven solely by the motor 42.

[0042] The first control unit 52 is configured to control the motor 42 so that the assist force is less than or equal to the maximum value MX.

[0043] Preferably, the first control unit 52 is configured to change the output fluctuation suppression level L of the motor 42. As the output fluctuation suppression level L of the motor 42 increases, the rate of change of the motor 42 output per unit time decreases in relation to the rate of change of the motor 42 control parameters per unit time. As the output fluctuation suppression level L of the motor 42 decreases, the rate of change of the motor 42 output per unit time increases in relation to the rate of change of the motor 42 control parameters per unit time. The control parameters of the motor 42 are the human driving force H or the rotational speed C of the crankshaft. The output fluctuation suppression level L of the motor 42 is inversely proportional to the response speed of the motor 42. The response speed of the motor 42 is represented by the rate of change of the motor 42 output per unit time in relation to the rate of change of the motor 42 control parameters per unit time. As the output fluctuation suppression level L of the motor 42 increases, the response speed of the motor 42 decreases.

[0044] The first control unit 52 changes the suppression level L by, for example, a filter circuit. The filter includes, for example, a low-pass filter having a time constant. The first control unit 52 changes the suppression level L by changing the time constant of the filter. The first control unit 52 may also change the suppression level L by changing the gain for calculating the output of the motor 42 from the human power driving force H. The filter circuit is configured, for example, by executing predetermined software in the arithmetic processing unit.
