PROBLEM TO BE SOLVED: To prevent steering of handles from inappropriately interfering with auxiliary driving force control.SOLUTION: A bicycle with an electric motor includes: an auxiliary driving system for making a motor generate an auxiliary driving force with a magnitude corresponding to a tread force applied to a pedal, and driving a front wheel or a rear wheel by the auxiliary driving force; handles connected to the front wheel; and an auxiliary driving force control part for executing reduction processing of reducing the magnitude of the auxiliary driving force when a vehicle state becomes a predetermined state, and not executing the reduction processing when the vehicle state becomes the predetermined state by the steering of the handles.SELECTED DRAWING: Figure 4
【課題】ハンドルの操舵が補助駆動力制御に不適切に介入することを防止する【解決手段】電動機付自転車は、ペダルに加えられた踏力に応じた大きさの補助駆動力をモータによって発生させ、補助駆動力によって前輪または後輪を駆動する補助駆動系と、前輪に接続されたハンドルと、車両の状態が所定状態となった場合に補助駆動力の大きさを低減する低減処理を実施し、車両の状態がハンドルの操舵を伴って所定状態になった場合には低減処理を実施しない補助駆動力制御部と、を含む。【選択図】図4
