摘要： A system and a method of controlling a drive motor for a vehicle is disclosed. The system of controlling a drive motor for a vehicle may include: an engine and the drive motor as power sources; a data detector detecting a state data for controlling the drive motor; and a vehicle controller setting a motor demand power and a gear stage based on the state data. In particular, the vehicle controller generates a motor demand torque based on the motor demand power and the gear stage, checks a motor temperature after driving the drive motor based on the motor demand torque, and changes the gear stage based on the motor temperature.
