PURPOSE: An over current analysis apparatus for a vehicle motor is provided to accurately determine cover current of a motor regardless of temperatures. CONSTITUTION: A motor operating switch(4) is operated by a driver to drive a motor. A current detection sensor(6) senses the current of the motor. A battery voltage detection sensor(7) senses battery voltage. A motor driver(12) drives the motor. A switching unit(14) is controlled by control signals. A motor driving controller sets a reference value corresponding to the battery voltage and temperature, converts the sensed current of the motor through a transform equation, and compares the converted value with the reference value to determine over current. |
