摘要： A motor driving device and method for a vehicle are provided to adjust and diagnose an air-conditioning motor by sensing an output signal and a current of a feedback sensor. The motor driving device includes a feedback sensor that configured to output a feedback voltage by detecting a rotation angle of a motor. In addition, a controller is configured to generate a substantially constant current that corresponds to an operation state of the motor and determine a driving state of the motor by combining the constant current with the feedback voltage.

摘要： A power control apparatus includes: a first power supply device that supplies main power, a second power supply device that supplies auxiliary power, a power divider that divides the main power input from the first power supplier, a first controller connected to a first output terminal of the power divider to control power supply to a first in-vehicle load by connecting or disconnecting the main power and the auxiliary power, and a second controller connected to a second output terminal of the power divider to control power supply to a second in-vehicle load using the main power. The first controller and the second controller diagnose a power failure in cooperation with each other and supply redundancy power using the main power or the auxiliary power based on a power failure diagnosis result.
