Title:
人力駆動車用制御装置
Document Type and Number:
Japanese Patent JP6916140
Kind Code:
B2
Abstract:
A human-powered vehicle control device includes an electronic controller that controls a motor assisting in propulsion of a human-powered vehicle including a crank. The controller changes an assist force ratio generated by the motor to human drive force input to the crank accordingly to the human drive force and a crank rotational speed. The controller increases the ratio as the human drive force increases while the crank rotational speed is constant and the human drive force is in a first range. The controller controls the motor so that the ratio is larger for a case where the human drive force is a first predetermined value in a first range and the crank rotational speed is in a second range than for a case where the human drive force is the first predetermined value and the crank rotational speed is in a third range higher than the second range.
