The invention provides a motor control method and system, a vehicle and a storage medium. And in the running process of the target vehicle, the power battery provides electric energy for a first motor in the target vehicle so as to enable the first motor to run. And when the power battery is about to be in the high-power output state, the target power (the notch power of the power battery) is determined, and the engine in the target vehicle is controlled to drive the second motor to generate power at the notch power so as to directly provide electric energy for the first motor, so that long-time high-power output of the power battery is avoided. Namely, when the power battery is about to be in the high-power output state, the second motor can participate in driving work of the target vehicle, and the situation that only the power battery provides all power needed by the target vehicle within a long time is avoided. According to the scheme, frequent impact damage to the power battery due to the fact that the power battery is in a high-power output state for a long time in the running process of the target vehicle can be avoided, the failure time of the power battery can be prolonged, and the purchase and maintenance cost of the target vehicle is saved.
本申请提供电机的控制方法、系统、车辆及存储介质。在目标车辆行驶的过程中,由动力电池向目标车辆中的第一电机提供电能以使第一电机运转。在动力电池将要处于大功率输出状态时,确定目标功率(动力电池的缺口功率),并控制目标车辆中的发动机带动第二电机以缺口功率发电,以直接向第一电机提供电能,进而避免动力电池长时间的大功率输出。即当动力电池将要处于大功率输出状态时,第二电机会参与到目标车辆的驱动工作,不会在长时间内仅由动力电池提供目标车辆所需的全部功率。该方案能够避免目标车辆在行驶过程中动力电池在长时间内处于大功率输出状态,对动力电池频繁性的冲击危害,可延长动力电池的失效时间,节省目标车辆的购置维护成本。
