Title:

MOTOR CONTROL DEVICE FOR ELECTRICALLY ASSISTED VEHICLE, AND ELECTRICALLY ASSISTED VEHICLE

Document Type and Number:

WIPO Patent Application WO/2023/281846

Kind Code:

A1

Abstract:

In order to automatically perform regeneration in a moderate range even on a gentle downhill or flat ground, this motor control device has: a driving unit that performs driving or regeneration for a motor; and a control unit that sets a vehicle speed as a reference speed during a transition to a predetermined traveling or pedal operation state, and controls the driving unit to generate regenerative torque while the vehicle speed is between the reference speed and a lower limit speed determined on the basis of the reference speed. Another motor control device has a driving unit that performs driving or regeneration for a motor; and a control unit that sets a vehicle speed as a reference speed during a transition to a predetermined traveling or pedal operation state, and controls the driving unit to generate regenerative torque within a certain period of time from a timing when the vehicle speed becomes less than the reference speed or within a certain length of the traveling distance from said timing.
