To provide an electric assist bicycle in which motor stop against a human intention rarely occurs and the responsivity of motor stop along with a human intention is easily improved, and a method of controlling the motor.SOLUTION: An automobile is equipped with a torque sensor 59 that detects human driving force applied to a crank 52, a crank rotation speed detecting portion 65 that detects the rotation speed of the crank 52, and a motor 54 that generates assist driving force for assisting power rotating wheels 3 and 4. The bicycle 1 is equipped with a control device 70 that stops the motor 54 if determining that a state in which human driving force is a threshold value or less has been continuously kept and the rotation speed decreases by a predetermined rotation speed or more.SELECTED DRAWING: Figure 2
【課題】人の意に反するモータ停止が生じにくく、人の意に沿うモータ停止の応答性を高くし易い電動アシスト自転車、及びそのモータの制御方法を提供すること。【解決手段】自転車が、クランク52に付与された人力駆動力を検出するトルクセンサ59と、クランク52の回転数を検出するクランク回転数検出部65と、車輪3,4を回転させる動力を補助する補助駆動力を生成するモータ54を備える。自転車1が、人力駆動力が閾値以下になっている状態が継続的に維持されており、かつ、上記回転数が、所定回転数以上減少したと判定すると、モータ54を停止させる制御装置70を備える。【選択図】図2
