The present invention relates to an integrated motor controller system for electric vehicles. The purpose of the present invention is to provide an integrated motor controller system for electric vehicles, which has a fault diagnosis module formed by integrating a vehicle control unit (VCU) and a control area network (CAN) packet, allows the fault diagnosis module to collect the input/output monitoring values of a low-voltage direct current converter (LDC) and an inverter by CAN communication by the CAN packet and to diagnose faults such as the overcurrent and overvoltage of the elements, allows the VCU to receive the diagnosed information as feedback information through CAN communication, and performs integrated control of power system elements by the received feedback information, thereby increasing efficiency, functionality, and manageability. Therefore, as the specific means of the present invention to achieve the purposes, the fault diagnosis module formed by integrating the VCU and the CAN packet, the LDC, and the inverter are integrally mounted on one package board.

    본 발명은 전기자동차용 통합 모터 컨트롤러 시스템에 관한 것으로, 그 기술구현의 목적은 비이클컨트롤유닛(VCU))과 컨트롤에어리어네트워크(CAN) 패킷을 통합하여 고장진단모듈을 형성하고, 고장진단모듈에 있어, 컨트롤에어리어네트워크(CAN)패킷에 의한 CAN통신에 의해 저전압직류변환장치(LDC)와 인버터(Inverter)의 입출력 모니터링 값을 취합하여 그들 소자의 과전류 및 과전압 등의 고장을 진단하고, 진단된 정보를 비이클컨트롤유닛(VCU)으로 하여금 CAN통신을 통해 피드백 정보로 입력받게 하여, 그 입력된 피드백 정보에 의해 전력계통소자를 통합 제어할 수 있게 함으로써, 효율성과 기능성 그리고 관리성을 극히 증대시킬 수 있도록 한 전기자동차용 통합 모터 컨트롤러 시스템을 제공함에 있다. 따라서, 상기 목적을 달성하기 위한 본 발명의 구체적 수단으로는; 비이클컨트롤유닛(VCU)과, 컨트롤에어리어네트워크(CAN)패킷을 통합하여 형성한 고장진단모듈과, 저전압직류변환장치(LDC)와, 인버터(Inverter)를 하나의 패키지보드에 통합 탑재하여 달성한다.
