Title:
GRILLE SHUTTER OPENING/CLOSING CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/138910
Kind Code:
A1
Abstract:
Provided is a grille shutter opening/closing control device capable of appropriately opening and closing a grille shutter according to the environment outside a vehicle and the operating state of an air conditioner while ensuring the operation of the air conditioner, thereby achieving sufficient improvement of the operation efficiency of the vehicle. An air conditioner operating time ratio (RA/CON) that is the ratio of the operating time of an air conditioner (32) to the overall time is calculated. When the calculated air conditioner operating time ratio (RA/CON) is larger than the sum of a threshold value (RREF) calculated according to an ambient temperature (TAM) and a hysteresis constant (ΔR), a grille shutter (47) is opened (steps 29, 31, 73, 77). As a result, the cooling of a refrigerant in the air conditioner (32) can be accelerated and power consumption of the air conditioner (32) can be reduced. Therefore, the grille shutter (47) can be appropriately opened and closed according to the ambient temperature (TAM) and the operating rate of the air conditioner (32) while the operation of the air conditioner (32) is ensured, thereby achieving the improvement of fuel cost.
