Abstract:
1. A freeze detecting device for an active shutter of a vehicle, the freeze detecting device comprising: an air temperature detector to detect external air temperature; a load determiner to determine whether the load state of a heat source provided in an engine compartment is high or not; a shutter to open and close an external air inlet that is open in the front portion of the engine compartment; a driving mechanism to drive the shutter; a controller to control the driving mechanism; and an action detector to detect an active state of the driving mechanism, wherein the controller comprises: a second controller to control a radiator fan provided in the engine compartment, wherein, in a case that the freezing state is determined by the freeze determiner, the second controller outputs a radiator fan ON signal to the radiator fan so as to inhibit a temperature in the engine compartment from rising.
