The present invention relates to a preheating system of a vehicle exhaust purification apparatus for reducing harmful gas generated during cold startup, which is the initial stage of engine startup. A pressure sensor for detecting a pressure, a coolant sensor connected to a thermostat of a radiator, a control unit for receiving and processing a signal of the coolant sensor while receiving a signal from the detection sensor, and powering the battery according to the instruction of the control unit. Since the preheater is configured to be applied to the preheater, the preheating system is operated only when the vehicle is driven, and the preheating system is ineffective even if the door is opened when the driving purpose is not.
