Abstract
A human-powered vehicle control device includes a controller that is configured to control a motor assisting in propulsion of a human-powered vehicle. The controller is configured to control the motor in a first control state in a case where a first parameter increases. The first parameter includes at least one of rotational speed of a crank of the human-powered vehicle, power of human driving force input to the human-powered vehicle, acceleration of the human-powered vehicle, jerk of the human-powered vehicle, and inclination angle of the human-powered vehicle. The controller is configured to control the motor in a second control state that differs from the first control state in a case where the first parameter decreases.

A human-powered vehicle control device comprising:
- an electronic controller configured to control a motor assisting in propulsion of a human-powered vehicle, the electronic controller controlling the motor in accordance with a human driving force input to the human-powered vehicle,
- the electronic controller being configured to control the motor in a first control state in a case where a first parameter increases, the first parameter including an inclination angle of the human-powered vehicle,
- the electronic controller being configured to control the motor in a second control state that differs from the first control state in a case where the first parameter decreases,
- the electronic controller being further configured to control the motor so that a response speed of an output of the motor with respect to a change in the human driving force differs between the first control state and the second control state.
A human-powered vehicle control device comprising:
- an electronic controller configured to control a transmission in a human-powered vehicle including a crank and a drive wheel, the transmission changing a ratio of a rotational speed of the drive wheel to a rotational speed of the crank,
- the electronic controller being configured to control the transmission in a case where a first parameter increases, so as to switch the ratio between a predetermined first ratio and a predetermined second ratio in accordance with a second parameter related to a running state of the human-powered vehicle and a first transmission threshold value set for the second parameter, the first parameter including at least one of torque of human driving force input to the human-powered vehicle, power of the human driving force input to the human-powered vehicle, acceleration of the human-powered vehicle, jerk of the human-powered vehicle, and inclination angle of the human-powered vehicle, and
- the electronic controller being configured to control the transmission in a case where the first parameter decreases so as to switch the ratio between the predetermined first ratio and the predetermined second ratio in accordance with the second parameter and a second transmission threshold value that differs from the first transmission threshold value and is set for the second parameter.
A human-powered vehicle control device comprising:
- an electronic controller configured to control a motor assisting in propulsion of a human-powered vehicle, the electronic controller controlling the motor in accordance with a human driving force input to the human-powered vehicle,
- the electronic controller being configured to control the motor in a first control state in a case where a first parameter increases, the first parameter including at least one of rotational speed of a crank of the human-powered vehicle, power of human driving force input to the human-powered vehicle, acceleration of the human-powered vehicle, jerk of the human-powered vehicle, and inclination angle of the human-powered vehicle,
- the electronic controller being configured to control the motor in a second control state that differs from the first control state in a case where the first parameter decreases,
- the electronic controller being further configured to control the motor by changing a time constant so that a response speed of an output of the motor with respect to a change in the human driving force differs between the first control state and the second control state.
