PROBLEM TO BE SOLVED: To provide an electric power assisted bicycle capable of achieving more comfortable travelling when a rider pedals the bicycle while swinging a bicycle body right and left.SOLUTION: An electric power assisted bicycle includes a torque sensor for detecting tread force applied to a pedal, an inclination angle sensor for detecting the swing of the bicycle body in the right and left directions, an electric motor for assisting the drive of the drive wheel by a rider, and a control device for controlling the electric motor based on the tread force applied to the pedal. The control device includes, as control modes for the electric motor, a first mode for normal travelling, and a second mode for assisting the drive of the drive wheel by the control different from the first mode when it is determined that the rider is travelling while swinging the bicycle body in the right and left directions at least based on the output of the inclination angle sensor.SELECTED DRAWING: Figure 5

    【課題】運転者が車体を左右に揺らしながら自転車を漕ぐ場合に、より快適な走行を実現できる電動補助自転車を提供する。【解決手段】電動補助自転車は、ペダルに加えられる踏力を検知するためのトルクセンサと、車体の左右方向への揺れを検知するための傾斜角センサと、運転者による駆動輪の駆動を補助する電動モータと、前記ペダルに加えられる踏力に基づいて前記電動モータを制御する制御装置と、を有している。前記制御装置は、前記電動モータの制御モードとして、通常走行において行う第1モードと、少なくとも傾斜角センサの出力に基づいて運転者が車体を左右方向に揺らしながら走行していると判断する場合に、第1モードとは異なる制御で駆動輪の駆動を補助する第2モードとを有している。【選択図】 図5
