To provide a wheelchair that allows operating force of the wheelchair to be reduced in spite of its simple configuration and control content while eliminating the need to detect force applied by a wheelchair rider and a care-giver, and is excellent in speed controllability.SOLUTION: When an inclined state of a travelling path is the upgrade, assisting force is determined so that the assisting force is constant in a predetermined gradient range, and the assisting force is less than the force with which a wheelchair in a resting state on a travelling path starts to move in an ascending direction. An electric motor 25 is controlled so as to generate the determined assisting force.SELECTED DRAWING: Figure 1
【課題】搭乗者や介助者が加える力の検出を不要して簡単な構成及び制御内容としながら車椅子の操作力を軽減し、かつ、速度のコントロール性の良好な車椅子を提供する。【解決手段】走行路の傾斜状態が登り勾配である場合に、所定の勾配範囲内で補助力が一定となるように、かつ、補助力が、走行路で静止状態にある車椅子が登り方向に動き出す力未満となるように決定する。決定された補助力を発生するように電動モータ25を制御する。【選択図】図1
