A human-powered vehicle control device includes an electronic controller that controls a motor. The motor assists in propulsion of a human-powered vehicle including a transmission configured to change, in steps, a first ratio of a rotational speed of a drive wheel to a rotational speed of a rotary body to which human drive force is input. The controller controls the motor in a first control state if the first ratio is changed by only one step during a predetermined period or a signal is received for changing the first ratio by one step during the predetermined period. The controller controls the motor in a second control state that differs from the first control state if the first ratio is changed by at least two steps during the predetermined period or a signal is received for changing the first ratio by at least two steps during the predetermined period.

A track estimation device includes: a reliability determination unit configured to determine the reliability of satellite positioning information; an update timing determination unit configured to determine the timing of updating a parameter to estimate track of cycling based on the reliability of satellite positioning information; and an update unit configured to update the parameter based on a result of the timing determination. When the reliability determination unit determines that reliability of the satellite positioning information is low, the track estimation unit estimates the track based on the parameter by autonomous navigation.
