To improve an assisted feeling during traveling on a curve, in an electric assisted bicycle.SOLUTION: An electric assisted bicycle 10 includes: a vehicle body motion sensor 63 that detects a change in a posture of a vehicle body relative to a road surface; a torque sensor 62 that detects a pedaling force of a pedal; a motor 3 that generates an assisting force for assisting the pedaling force; a motor control unit 5 that controls the assisting force of the motor 3 according to the pedaling force; and a sharp curve travel detection unit 6 that, based on information obtained from the vehicle body motion sensor 63, detects the electric assisted bicycle 10 traveling on a sharp curve in a state where the vehicle body is leaned at a predetermined angle or more in a right and left direction from an upright state. The motor control unit 5 controls the assisting force according to a detection result of the sharp curve travel detection unit 6.SELECTED DRAWING: Figure 3

    【課題】電動補助自転車において、カーブ走行時におけるアシストフィーリングを改善する。【解決手段】電動補助自転車10は、車体の路面に対する姿勢の変化を検出する車体運動センサ63と、ペダルの踏力を検出するトルクセンサ62と、踏力を補助する補助力を発生させるモータ3と、踏力に応じてモータ3の補助力を制御するモータ制御部5と、車体運動センサ63から得られる情報により、電動補助自転車10が、車体を直立状態から左右方向に所定角度以上傾けた状態で急カーブを走行していることを検出する急カーブ走行検出部6と、を備える。モータ制御部5は、急カーブ走行検出部6の検出結果に応じて補助力を制御する。【選択図】図3
