The invention provides a motor rotating speed control method for a distributed driving automobile, and the method comprises the steps: determining a first rotating speed change threshold value of a distributed driving motor in a task period, and calculating a second rotating speed change threshold value of the distributed driving motor based on the automobile speed through an Ackerman steering model and an automobile speed change threshold value in the task period; calculating a theoretical rotating speed threshold value of the distributed driving motor; calculating a transient expected rotating speed of the distributed motor at the current moment based on the theoretical rotating speed threshold value; and the motor rotating speed of the distributed motor automobile is adjusted according to the transient expected rotating speed of the distributed motor at the current moment. According to the method, the transient expected rotating speed of the distributed motor at the current moment can be controlled to be equal to the expected rotating speed of the distributed motor, so that the time of reaching the expected rotating speed of the distributed motor is consistent, the consistency of the transient expected rotating speed change of the distributed motor at the current moment is ensured, and the safety of vehicle driving is improved.

    本发明提供了一种分布式驱动汽车的电机转速控制方法,该方法包括:确定分布式驱动电机在任务周期内的第一转速变化阈值,利用阿克曼转向模型和任务周期内车速的变化阈值计算所述分布式驱动电机基于车速的第二转速变化阈值;计算分布式驱动电机的理论转速阈值;基于理论转速阈值计算分布式电机当前时刻瞬态期望转速;根据分布式电机当前时刻瞬态期望转速调整所述分布式电机汽车的电机转速。本发明能够控制分布式电机当前时刻瞬态期望转速分别等于分布式电机的预期转速,使得分布式电机达到预期转速的时间一致,从而保证了分布式电机当前时刻瞬态期望转速变化的一致性,提高了车辆行驶的安全性。
