The invention relates to the technical field of electric driving systems, and provides a control method and device of an electric driving system, electronic equipment and a storage medium. The control method of the electric drive system comprises the steps that in response to a target torque output requirement, an inverter is controlled to output target current to a motor, the target torque output requirement represents that a vehicle needs target torque higher than the peak torque of the motor, and the target current is larger than the peak current of the inverter; and when the inverter outputs the target current for a preset time, controlling the inverter to recover the working mode before outputting the target current. According to the method, when it is recognized that the vehicle has the target torque output requirement under the extreme working condition, the inverter is controlled to output larger current within a short time, the motor outputs the target torque higher than the peak torque within the short time, and therefore the vehicle obtains larger traction force. Hardware configuration of the electric driving system does not need to be changed, and energy consumption and efficiency of the electric driving system under the conventional use working condition are not affected.

    本发明涉及电驱动系统技术领域,提供电驱动系统的控制方法、控制装置、电子设备和存储介质。电驱动系统的控制方法包括:响应于目标扭矩输出需求,控制逆变器向电动机输出目标电流,其中,目标扭矩输出需求表征车辆需要高于电动机的峰值扭矩的目标扭矩,目标电流大于逆变器的峰值电流;当逆变器输出目标电流达预设时间,控制逆变器恢复输出目标电流之前的工作模式。本发明当识别到车辆在极端工况下存在目标扭矩输出需求,通过控制逆变器在短时间内输出更大的电流,使电动机在短时间内输出比峰值扭矩更高的目标扭矩,从而车辆获得更大的牵引力。本发明无需改变电驱动系统的硬件配置,不影响电驱动系统在常规使用工况下的能耗和效率。
