Beschreibung
Zusammenfassung:	The present invention provides a method for monitoring and identifying sensor faults in an electric drive system, comprising the steps of: collecting corresponding data by means of various sensors in an electric drive system of a vehicle; inputting the collected data to an already-established sensor fault mode identification model; and determining whether a fault mode exists and a fault mode type on the basis of the collected data by means of the sensor fault mode identification model. According to the method of the present invention, it is possible to quickly determine a fault mode caused by a sensor in an electric drive system, and a fault mode type.
