The invention belongs to the technical field of automobiles, and discloses a switching frequency control method and device, equipment and a storage medium. When a target working condition data set is obtained, multiple to-be-detected working conditions are determined according to the target working condition data set; performing noise value detection on each to-be-detected working condition, and determining a working condition noise value of each to-be-detected working condition; adjusting the initial switching frequency according to the working condition noise value of each to-be-tested working condition and a target noise threshold value, and determining a target switching frequency of each to-be-tested working condition; and formulating a switching frequency control strategy according to the generator rotating speed range of each to-be-tested working condition and the target switching frequency of each to-be-tested working condition. Through the above mode, the initial switching frequency is adjusted based on the target noise threshold and the working condition noise value of the to-be-tested working condition to obtain the target switching frequency, and the switching frequency control strategy is determined according to the generator rotating speed range and the target switching frequency, so that the vehicle NVH performance and the generator efficiency are taken into consideration; and a switching frequency control strategy is efficiently and accurately formulated.
