Title:
ABNORMALITY DETECTION FOR ELECTRIC DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2024/088129
Kind Code:
A1
Abstract:
The present application relates to abnormality detection for an electric drive system. An abnormality detection method for an electric drive system comprises the following steps: collecting a vibration signal by means of a vibration sensor, wherein the vibration sensor is coupled onto an inner housing of an electric motor controller in the electric drive system by means of an acceleration plate; and generating diagnosis data according to the vibration signal, and sending the diagnosis data, such that a receiver determines, on the basis of the diagnosis data, whether an abnormality occurs in the electric drive system.
