To enable man power to be assisted more appropriately when a power-assisted vehicle is pushed or pulled with man power.SOLUTION: A motor control device of the present invention comprises: an inverter that causes a motor of a power-assisted vehicle to carry out power-running drive or regenerative brake; and a control unit that determines a control mode for the motor on the basis of the direction of man power or a rotating direction of the motor, which is obtained when a user pushes or pulls the power-assisted vehicle with hands, and controls the inverter such that torque based on man power in the determined control mode is caused by the motor. Examples of the control mode are as follows: when the direction of man power is positive and the rotating direction of the motor is positive, power running in a positive direction is determined; when the direction of the man power is positive and the rotating direction of the motor is negative, regeneration in a negative direction or power running in the positive direction is determined; when the direction of man power is negative and the rotating direction of the motor is positive, regeneration in the positive direction or power running in the negative direction is determined; and when the direction of man power is negative and the rotating direction of the motor is negative, power running in the negative direction is determined.SELECTED DRAWING: Figure 3

    【課題】電動アシスト車を人力にて押したり引いたりする際に、より適切に人力をアシストできるようにする。【解決手段】本発明のモータ制御装置は、電動アシスト車のモータを力行駆動又は回生制動させるインバータと、ユーザが電動アシスト車を手で押す又は手で引く状態における人力の方向及びモータの回転方向に基づきモータの制御モードを決定し、決定された制御モードにおいて人力に基づくトルクをモータに生じさせるようにインバータを制御する制御部とを有する。制御モードの例として、人力の方向が正で且つモータの回転方向が正である場合、正方向力行を決定し、人力の方向が正で且つモータの回転方向が負である場合、負方向回生又は正方向力行を決定し、人力の方向が負で且つモータの回転方向が正である場合、正方向回生又は負方向力行を決定し、人力の方向が負で且つモータの回転方向が負である場合、負方向力行を決定する。【選択図】図3
