Abstract
A control device for an electric pump, the electric pump pumping a cooling medium, the control device includes a controller configured to determine a presence of an abnormality in the electric pump when a temperature of the cooling medium is higher than a threshold value and the electric pump is locked. The threshold value being predetermined as a temperature that is higher than a freezing point of the cooling medium.
Claims
exact text as granted — not AI-modifiedWhat is claimed is:
1 . A control device for an electric pump, the electric pump pumping a cooling medium, the control device comprising:
a controller configured to determine a presence of an abnormality in the electric pump when a temperature of the cooling medium is higher than a threshold value and the electric pump is locked, the threshold value being predetermined as a temperature that is higher than a freezing point of the cooling medium.
2 . The control device according to claim 1 , wherein the controller is configured to intermittently drive the electric pump when the temperature of the cooling medium is equal to or lower than the threshold value and the electric pump is locked.
3 . The control device according to claim 2 , wherein the controller is configured to stop the intermittent driving of the electric pump, when the electric pump rotates after the electric pump is locked in a condition in which the temperature of the cooling medium is equal to or lower than the threshold value.Join the waitlist — get patent alerts
