Abstract
A control device for a cooling device that cools an internal combustion engine using cooling water includes circuitry configured to: determine boiling of the cooling water; and control a flow rate of the cooling water based on a result of the boiling determination. The circuitry determines the boiling of the cooling water based on a difference between a maximum value and a minimum value of a temperature of the cooling water during a predetermined time and a subcooling degree that is based on the temperature of the cooling water.
Claims8
A control device for a cooling device that cools an internal combustion engine using cooling water, the control device comprising:
- circuitry, wherein
- the circuitry is configured to:
- determine boiling of the cooling water;
- and
- control a flow rate of the cooling water based on a result of the boiling determination, and
- the circuitry determines the boiling of the cooling water based on a difference between a maximum value and a minimum value of a temperature of the cooling water during a predetermined time and a subcooling degree that is based on the temperature of the cooling water.
A control method performed by a processor to control a cooling device that cools an internal combustion engine using cooling water, the control method comprising:
- determining boiling of the cooling water based on a difference between a maximum value and a minimum value of a temperature of the cooling water during a predetermined time and a subcooling degree that is based on the temperature of the cooling water;
- and
- controlling a flow rate of the cooling water based a result of the determination of the boiling.
A non-transitory computer-readable medium storing a control program for causing a processor to execute a process to control a cooling device that cools an internal combustion engine using cooling water, the process comprising:
- determining boiling of the cooling water based on a difference between a maximum value and a minimum value of a temperature of the cooling water during a predetermined time and a subcooling degree that is based on the temperature of the cooling water;
- and
- controlling a flow rate of the cooling water based a result of the determination of the boiling.
