The invention discloses an automobile grade permanent magnet synchronous motor controller suitable for an electric automobile. The automobile grade permanent magnet synchronous motor controller comprises a control unit arranged in a shell with a sealing cover. The power input end of the control unit is connected with an automobile 12 V direct current power source through a power isolation module. A signal interface of the control unit is arranged on the side wall of the shell, is used for being connected with a controller VCU through a can bus, a calibration upper computer with the parameter calibration function and the program downloading function through a calibration can bus, and the signal output end of a rotary transformer arranged on a permanent magnet synchronous motor shaft through a signal line. The automobile grade permanent magnet synchronous motor controller has the advantages that an automobile grade power module and an automobile grade control chip are adopted, electromagnetic compatibility is fully considered, the structure is simple and compact, assembly is easy, productization of design of all the parts is easy, and high safety, stability and reliability are achieved.
