The invention relates to the technical field of motor control, and provides a motor control method and device based on multi-motor driving. The method comprises the steps that at least one target motor capable of being in a non-working state is determined from all motors according to the current working condition of the new energy driving tool; and the target motor is controlled to be separated from a synchronizer on a driving shaft of the new energy driving tool, and an inertial energy storage device formed by the target motor and a gear connected with the target motor is obtained. According to the motor control method based on multi-motor driving, energy consumption can be reduced, electric power resources can be saved, the charging and discharging working conditions of the power battery can be dynamically adjusted, and the service life of the power battery can be prolonged.

    本申请涉及电机控制技术领域,提供一种基于多电机驱动的电机控制方法及装置。所述方法包括:根据新能源驾驶工具的当前工况,从各电机中确定可处于非工作状态的至少一个目标电机;控制所述目标电机,脱离所述新能源驾驶工具的驱动轴上的同步器,获取由所述目标电机以及连接所述目标电机的齿轮形成的惯性储能装置。本申请实施例提供的基于多电机驱动的电机控制方法能够减少能量消耗,节约电力资源,并能够动态调节动力电池的充放电工况,以延长动力电池的使用寿命。
