The invention relates to the technical field of electric bicycle theft prevention, and particularly discloses a motor control method and device for electric bicycle theft prevention, and the method comprises the steps: obtaining a current Hall sector of a motor and a center angle of the current Hall sector, and determining the current Hall sector as a locking sector; when it is detected that the motor rotates from the first sector to the second sector, the voltage value of the motor is increased, and the voltage vector direction of the motor is set to be the direction corresponding to the center angle; the first sector is the next Hall sector of the locked sector, and the second sector is the next Hall sector of the first sector. According to the scheme, the electric vehicle can be prevented from being stolen, and motor shaking can be effectively avoided.

    本说明书涉及电动车防盗技术领域,具体地公开了一种用于电动自行车防盗的电机控制方法及装置,其中,该方法包括:获取电机的当前霍尔扇区以及当前霍尔扇区的中心角度,将所述当前霍尔扇区确定为锁定扇区;在检测到电机经由第一扇区转动到第二扇区的情况下,增加电机的电压值,并将电机的电压矢量方向设置为所述中心角度对应的方向;所述第一扇区为所述锁定扇区的下一个霍尔扇区,所述第二扇区为所述第一扇区的下一个霍尔扇区。上述方案可以实现电动车防盗,还可以有效避免电机抖动。
