摘要:
The present invention relates to a circuit and method for detecting a short and a disconnection of a resolver for a Hybrid Electric Vehicle (HEV), which can accurately analyze and detect the fault code of the resolver which detects the speed of a drive motor for an HEV and the angle of a rotator for an HEV.For this, the circuit of the present invention is configured such that resistors for detection of a short/disconnection are connected between output signal terminals of a resolver which are connected to input terminals of an RDC connected to a CPU, and the CPU measures certain voltages, obtained according to voltage division by the resistors for detection of a short/disconnection and pull-up resistors connected between a power source and the output signal terminals, with reference to differential signals which are output signals provided to the RDC through the output signal terminals.
