FREEZE DETECTING DEVICE FOR ACTIVE SHUTTER OF VEHICLE

摘要

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.

主权项

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:
an opening action instructing unit to output an opening signal to the driving mechanism, in the case that the external air temperature detected by the external air temperature detector is at or below a freezing determination temperature and the load determiner has determined that the load is high;a freeze determiner to estimate a freezing state, in the case that the action detector has not detected an action by the driving mechanism in the event that an opening signal from the opening action unit is output to the driving mechanism; anda warning display instructing unit to display a warning on a display, in the case that a freezing state is determined by the freeze determiner.
