Automobile electric compressor control method, computer device and storage medium

Abstract

The present invention discloses a method for controlling an electric compressor for an automobile, a computer device, and a storage medium. The present invention sets an upper speed limit for the electric compressor based on noise source parameters and controls the speed of the electric compressor to be below the upper speed limit, thereby controlling the operating noise of the electric compressor to be within a range less than a threshold value. The noise source represented by the noise source parameters is thereby used to mask the operating noise of the electric compressor, thereby making the operating noise of the electric compressor less noticeable to the driver and passengers. Since the noise source represented by the noise source parameters is generally more predictable than the operating noise of the electric compressor, the method for controlling an electric compressor for an automobile in an embodiment can reduce the content of unpredictable noise components in the noise heard by the driver and passengers, thereby reducing the discomfort caused by the noise. The present invention is widely applicable to the field of automotive technology.
