Abstract
An overheat prevention method includes an rpm comparison step of comparing an engine revolution per minute (rpm) speed with a preset rpm speed by a controller when requiring an engagement of an engine clutch, a temperature comparison step of comparing a temperature of a transmission clutch with a preset temperature by the controller when it is determined that the engine rpm speed is less than the preset rpm speed at the rpm comparison step, and a serial drive mode control step of releasing the engine clutch and engaging the transmission clutch, and controlling a hybrid starter generator (HSG) to charge a battery using engine power to provide driving power to a motor by the controller when it is determined that the temperature of the transmission clutch is higher than the preset temperature at the temperature comparison step.
