The invention relates to a carrier frequency control method and device for a motor controller, electronic equipment and a storage medium, and the method comprises the steps: obtaining the state information of a target vehicle; determining a carrier frequency control mode based on the driving mode of the target vehicle, and adjusting the carrier frequency of a motor controller of the target vehicle based on the carrier frequency control mode and the driving parameters of the target vehicle; and reducing the carrier frequency of the motor controller based on the driving parameters of the target vehicle, obtaining the corrected carrier frequency, and outputting the corrected carrier frequency. According to the invention, the carrier frequency of the motor controller can be adjusted and corrected to reduce the junction temperature of the motor controller, so that the continuous working capability of the motor controller is improved, and the cross-country trafficability of the vehicle is improved by improving the continuous working capability of the motor controller. Compared with the prior art, the method has the advantages that hardware is not changed, and cost is not increased.

    本申请涉及一种电机控制器的载频控制方法、装置、电子设备和存储介质,其中,电机控制器的载频控制方法包括:获取目标车辆的状态信息;基于目标车辆的驾驶模式确定载频控制模式,并基于载频控制模式和目标车辆的行车参数调整目标车辆的电机控制器的载频;基于目标车辆的行车参数降低电机控制器的载频并得到修正后的载频,并输出修正后的载频。本申请能够对电机控制器的载频进行调整修正,以降低电机控制器结温,进而提升电机控制器持续工作能力,从而通过提升电机控制器持续工作能力,提高车辆越野通过性。与现有技术相比,其具有不改变硬件不增加成本的优点。
