The embodiment of the invention discloses an electric drive system control method and device, a vehicle and a storage medium. The method comprises the steps of: according to the current load of a motor in the electric drive system, determining a target discontinuous pulse width modulation DPWM mode in a preset modulation mode table, wherein the preset modulation mode table comprises the corresponding relation between the load and a preset number of DPWM modes; and based on the target DPWM mode, determining a DPWM waveform through a random zero vector modulation mode, and controlling the electric drive system through the DPWM waveform. According to the technical scheme provided by the embodiment of the invention, the efficiency of the electric driving system can be improved, and the noise,vibration and acoustic vibration roughness of the whole vehicle can be reduced.

    本发明实施例公开了一种电驱动系统控制方法、装置、车辆及存储介质。其中,该方法包括:根据电驱动系统中电机的当前负载,在预设调制方式表中确定目标不连续脉冲宽度调制DPWM方式,其中,所述预设调制方式表中包括负载和预设数量的DPWM方式的对应关系;基于所述目标DPWM方式,通过随机零矢量调制方式,确定DPWM波形,并通过所述DPWM波形对电驱动系统进行控制。本发明实施例提供的技术方案,可以提高电驱动系统效率以及降低整车的噪声、振动与声振粗糙度。
