COOLING APPARATUS
First Claim
1. A cooling apparatus configured to cool a device mounted in a vehicle, the cooling apparatus comprising:
- a pump configured to circulate a refrigerant between the device and a radiator, anda controller configured to provide an output command value to the pump, and to monitor occurrence of abnormality of the pump,whereinthe controller is configured capable of executing;
vehicle-speed-based control including shifting the output command value when a vehicle speed falls below a predetermined vehicle speed threshold value; and
monitoring control including;
measuring an abnormality duration time during which a rotational speed of the pump is deviating from a predetermined allowable range; and
outputting a notification signal notifying the abnormality of the pump when the measured abnormality duration time exceeds a predetermined time threshold value, andwhile the controller is measuring the abnormality duration time in the monitoring control, the controller inhibits the vehicle-speed-based control.

Abstract
A cooling apparatus may be configured to cool a device mounted in a vehicle. The cooling apparatus may include: a pump configured to circulate a refrigerant between the device and a radiator, and a controller configured to provide an output command value to the pump, and to monitor occurrence of abnormality of the pump. The controller may be configured capable of executing: vehicle-speed-based control including shifting the output command value when a vehicle speed falls below a predetermined vehicle speed threshold value; and monitoring control including: measuring an abnormality duration time during which a rotational speed of the pump is deviating from a predetermined allowable range; and outputting a notification signal notifying the abnormality of the pump when the measured abnormality duration time exceeds a predetermined time threshold value. While the controller is measuring the abnormality duration time in the monitoring control, the controller may inhibit the vehicle-speed-based control.
