GRILLE SHUTTER CONTROL DEVICE
Document Type and Number:
Japanese Patent JP2020029119
Kind Code:
A
Abstract:
To provide a grille shutter control device which can inhibit accumulation of residual strain in an exhaust system component.SOLUTION: A control device 200 is mounted on a vehicle 100 including a grille shutter 47 which is disposed in an inflow passage 120, which guides travel window from a grille 130 to an interior of an engine compartment 110, and opens or closes the inflow passage 120. The control device 200 includes an opening/closing control part 220 which controls opening/closing of the grille shutter 47. The opening/closing control part 220 carries out warming facilitation control which keeps the grille shutter 47 in a closed state until warming of an engine 10 is completed. Further, the control device 200 includes a temperature acquisition part 210 which acquires a temperature of an exhaust manifold 15 which is an exhaust system component of the engine 10. The opening/closing control part 220 carries out temperature variation inhibition control, in which the grille shutter 47 is closed, when a temperature of the exhaust manifold 15 acquired by the temperature acquisition part 210 becomes a predetermined temperature or lower after completion of the warming facilitation control.SELECTED DRAWING: Figure 1
