Zusammenfassung:A control method and system are provided for preventing a motor from overheating when a TMED hybrid vehicle is driven to thus improve driving performance by operating an engine before limiting motor output based on a driving state while the vehicle is driven in an EV mode, and the current temperature of the motor. The method includes monitoring a motor temperature of a hybrid vehicle and operating an engine when the current motor temperature of the motor is a first motor temperature or greater when the vehicle is driven in an EV mode. In addition, motor output is limited when the current motor temperature is equal to or greater than a third motor temperature, which is greater than the first motor temperature, after the engine is operated.
