    Abstract: An engine cooling system including a refrigerant circulation flow channel passing through an engine, an electric refrigerant pump, an electromagnetic valve arranged in the refrigerant circulation flow channel, and a control unit. In the engine cooling system, when the electric refrigerant pump is stopped and the voltage application to the electromagnetic valve is shut off when the electromagnetic valve is closed and the electric refrigerant pump is in operation, the voltage application to the electromagnetic valve is shut off when a first predetermined time period has passed after the electric refrigerant pump is stopped. When the engine is intermittently stopped during warming up of the engine, current application to the electromagnetic valve is shut off while the closed state of the electromagnetic valve is maintained.

    Abstract: The pore clogging determination apparatus tentatively determines clogging of a pore (micropore) based on the rate of increase in a coolant temperature at an engine outlet. When the presence of pore clogging has been tentatively determined, the apparatus increases a rotation speed of a coolant pump to determine whether or not the coolant pump is idling. When it has been determined that the coolant pump is idling, the apparatus finalizes the determination of the clogging of the pore (micropore). This suppresses an erroneous determination of clogging of the pore that allows the coolant to flow In an engine cooling system.

    Abstract: In SOC estimation device, the first estimation unit 36 estimates a reference value of SOC of the battery based on the voltage of the chargeable/dischargeable battery (auxiliary battery). The second estimation unit 38 estimates the estimated value of SOC of the battery based on the estimated reference value and the integrated value of the current of the battery. When the first estimation unit is not performing the process of estimating the reference value, the voltage of the battery is controlled within the first range. When the first estimation unit is executing the process of estimating the reference value, the voltage of the battery is controlled within the second range, and the second range includes a specific range outside the first range. The first estimation unit estimates the reference value based on the voltage of the battery when the value falls within the specific range.
