Control device for human-powered vehicle

A control device for a human-powered vehicle, the control device comprising:

• an electronic controller configured to control a motor that applies a propulsion force to the human-powered vehicle,
• the human-powered vehicle including the motor and a transmission device for assisting a human driving force,
• the electronic controller being configured to assist in propulsion of the human-powered vehicle with the motor in a state in which the human-powered vehicle is propelled by the human driving force, and
• in response to determining that a transmission ratio of the transmission device is changed, the electronic controller being configured to decrease an assist level of the motor in accordance with the human driving force input to the human-powered vehicle, and being configured to control the motor so that the assist level is greater for a case where the human driving force is a first human driving force than the assist level for a case where the human driving force is a second human driving force that is less than the first human driving force, and
• the electronic controller being configured to increase the assist level in a case where a predetermined period elapses after the assist level has decreased,
• the predetermined period includes a period during which a rotation amount of a wheel of the human-powered vehicle becomes a predetermined rotation amount, and
• the predetermined rotation amount is greater than or equal to 30 degrees and less than 460 degrees.
