  • Cooling control device
    Patent number: 10465594
    Abstract: A cooling control device includes a switching valve, coolant transporting units, an electric motor, a function determination unit, and a first controller. The switching valve has coolant outlets through which a coolant flows. The coolant transporting units are disposed in contact with the switching valve and connected to or shut off from the coolant outlets. The electric motor switches between connecting and shutting off the coolant outlets and the coolant transporting units by operation of the switching valve. The function determination unit detects decrease in an operating function of the switching valve. The first controller sets an amount of current applied to the electric motor to operate the switching valve after the operating function of the switching valve is determined to be decreased, to be larger than an amount of current applied to the electric motor to operate the switching valve when the switching valve operating function is not decreased.
