Abstract:
The present invention provides a cooling device for an internal combustion engine of a vehicle. While the vehicle is in a decelerating state and while the internal combustion engine is in an idle reduction state, the cooling device increases the ratio of the cooling water circulation rate through a first path which extends through a heater core and a radiator while reducing the ratio of the cooling water circulation rate through a second path which bypasses the heater core and radiator. In addition, the cooling device increases the discharge flow rate of the electric water pump while the vehicle is in a decelerating state, and maintains the electric water pump in an operating state during idle reduction. Thus, the present invention allows accelerating the temperature decrease of the cylinder head during idle reduction, as well as improving fuel economy during acceleration when the vehicle is started.

Claim (Index 14):
A method for controlling a cooling device for an internal combustion engine of a vehicle, the cooling device including:\n a cooling water circulation passage including:\n a first cooling water line which extends through a cylinder head of the internal combustion engine and through a radiator, and bypasses a cylinder head of the internal combustion engine; \n a second cooling water line which extends through the cylinder block, and bypasses the cylinder head and the radiator; \n a third cooling water line which extends through the cylinder head and heater core, and bypasses the cylinder block and the radiator; and \n a fourth cooling water line which extends through the cylinder head and a heat exchanger for a powertrain of the internal combustion engine; \n an electric water pump for circulating cooling water through the cooling water circulation passage; and switching means for switching between a plurality of modes including: an all-path flow mode for opening all the first to fourth cooling water lines; and an automatic stop mode for reducing opening areas of the second and fourth cooling water lines as compared to in the all-path flow mode, the control method comprising the steps of: detecting a decelerating state of the vehicle; increasing a discharge flow rate of the electric water pump upon detecting the decelerating state of the vehicle; detecting an automatic stop state of the internal combustion engine which is assumed when the vehicle stops after the decelerating state; and maintaining the electric water pump in an operating state during the automatic stop state; causing the switching means to switch to the automatic stop mode upon detecting the decelerating state of the vehicle; and causing the switching means to switch to the automatic stop mode during the automatic stop state.
