Abstract
A freeze detecting device for an active shutter of a vehicle includes an engine control unit that outputs an opening signal, opens an active shutter, takes in travelling wind to an engine compartment, and inhibits heat damage when an external air temperature is at or below a freezing determination temperature and also a load state is high. On the other hand, when an opening signal is output from the engine control unit but the active shutter does not perform an opening action, a determination of being frozen solid is made, a warning is displayed on the display to warn the vehicle driver.
