Abstract
A method for diagnosing an abnormality of a vehicle cooling system using circulation of cooling water stored in a reservoir tank includes generating a diagnostic mode operation command based on state information of a vehicle including a disturbance factor, calculating an RPM of a water pump in response to the diagnostic mode operation command, and determining an abnormal state of the cooling system based on the RPM of the water pump being equal to or greater than a predetermined threshold.
Claims18
A method for diagnosing an abnormality of a vehicle cooling system using circulation of cooling water stored in a reservoir tank, the method comprising:
- generating, by a processor, a diagnostic mode operation command based on state information of a vehicle including a disturbance factor received from a sensor;
- determining, by the processor, an RPM of a water pump in response to the diagnostic mode operation command;
- determining, by the processor, an abnormal state of the cooling system based on the RPM of the water pump being equal to or greater than a predetermined threshold;
- and
- notifying, by the processor, the abnormal state after determining the abnormal state of the cooling system through a display.
A vehicle cooling system comprising:
- a reservoir tank configured to store cooling water;
- a water pump configured to circulate the cooling water;
- a sensor configured to sense a physical quantity for determining the disturbance factor;
- a display configured to show information on the abnormal state of the cooling system;
- and
- a processor configured to:
- generate a diagnostic mode operation command based on state information of a vehicle including a disturbance factor;
- determine an RPM of the water pump in response to the diagnostic mode operation command;
- determine an abnormal state based on the RPM of the water pump being equal to or greater than a predetermined threshold;
- and
- control the display to show information on the abnormal state after determining the abnormal state of the cooling system.
