The invention relates to the technical field of hydrogen energy automobiles, and particularly relates to a motor rotating speed jitter elimination method of a hydrogen energy automobile driving motorsystem. The method mainly comprises the steps that S1, after a whole automobile is started, a vehicle control unit identifies the driving state of the whole automobile and judges whether the whole automobile enters a motor rotating speed jitter elimination preparation state or not; S2, if the whole automobile in the step S1 does not enter the motor rotating speed jitter elimination preparation state, the operation in the step S1 is repeated; and if the whole automobile enters the motor rotating speed jitter elimination preparation state in the step S1, a motor rotating speed jitter eliminationcommand is correspondingly executed according to the gear state information and the whole automobile driving state information. According to the motor rotating speed jitter elimination method of thehydrogen energy automobile driving motor system, the problem of driving motor system jitter can be weakened or eliminated by adopting different torque loading modes according to different driving modes of the whole automobile, and a mechanical gap between driving motor systems can be eliminated during driving of the driving motor systems, so that motor rotating speed jitter elimination control isenabled to be simpler, safer and more reliable.

    本发明涉及氢能汽车技术领域,尤其涉及一种氢能汽车驱动电机系统的电机转速消抖方法,主要包括S1、整车启动后,整车控制器识别整车的驱动状态,并判断整车是否进入电机转速消抖预备状态;S2、若S1中整车未进入电机转速消抖预备状态,则重复S1的操作;若S1中整车进入电机转速消抖预备状态,则根据档位状态信息和整车驱动状态信息,对应的执行电机转速消抖命令。本发明所述的一种氢能汽车驱动电机系统的电机转速消抖方法,其可根据整车处于不同的驱动模式下,采用不同的扭矩加载方式来实现削弱或者消除驱动电机系统抖动问题,该种方法在驱动电机系统驱动时可消除驱动电机系统之间的机械间隙,使得电机转速消抖控制更加简单、安全和可靠。
