Title:
MOTOR CONTROL DEVICE FOR ELECTRICALLY ASSISTED VEHICLE, AND ELECTRICALLY ASSISTED VEHICLE
Document Type and Number:
WIPO Patent Application WO/2023/195276
Kind Code:
A1
Abstract:
In order to perform regenerative braking in a manner that complies more with the intent of an occupant, the motor control device according to an embodiment comprises: an inverter that causes a motor of an electrically assisted vehicle to perform power driving or regenerative braking; and a control unit that controls the inverter by determining, on the basis of a first condition or a second condition, the presence or absence of regenerative braking associated in advance with the first condition or the second condition, the first condition being about the crank angle that is the angle from a reference position of the crank in the case that the crank rotation speed which is the rotation speed of the crank in the electrically assisted vehicle is less than or equal to a first threshold, the second condition being about the cumulative crank rotation angle that is the cumulative rotation angle of the crank after the input torque caused by the rotation of the crank becomes less than or equal to a second threshold.
