Abstract
Methods and systems for managing a monitoring of an engine cooling system. A transient condition associated with an engine system is identified. A determination is made as to whether the transient condition is a delay condition based on whether the transient condition exceeds a transient threshold. A determination is made, in response to a determination that the transient condition is not the delay condition, as to whether a period of time that has passed since a previously identified delay condition meets a time threshold. Monitoring of a health of the engine cooling system is enabled in response to a determination that the period of time meets the time threshold.
Claims20
A method for managing a monitoring of an engine cooling system, the method comprising:
- identifying a transient condition associated with an engine system;
- determining whether the transient condition is a delay condition based on whether the transient condition exceeds a transient threshold;
- determining, in response to a determination that the transient condition is not the delay condition, whether a period of time that has passed since a previously identified delay condition meets a time threshold;
- and
- resuming modeling of an expected coolant temperature of the engine cooling system by a processor in response to a determination that the period of time meets the time threshold to thereby resume monitoring of a health of the engine cooling system.
A system comprising:
- an engine system including an engine cooling system;
- a sensor system coupled to the engine system;
- and
- a health manager in communication with the sensor system, wherein the health manager identifies a transient condition associated with the engine system based on sensor data received from the sensor system;
- determines whether the transient condition is a delay condition based on whether the transient condition exceeds a transient threshold;
- determines, in response to a determination that the transient condition is not the delay condition, whether a period of time that has passed since a previously identified delay condition meets a time threshold;
- and resumes modeling of an expected coolant temperature of the engine cooling system in response to a determination that the period of time meets the time threshold to thereby resume monitoring of a health of the engine cooling system.
A method for managing a monitoring of an engine cooling system, the method comprising:
- identifying a transient condition for an engine system for a current point in time;
- computing a transient threshold and a time threshold for the current point in time;
- determining whether the transient condition is a delay condition based on whether the transient condition exceeds the transient threshold;
- determining, in response to a determination that the transient condition is not the delay condition, whether a period of time that has passed since a previously identified delay condition meets the time threshold;
- resuming modeling of an expected coolant temperature of the engine cooling system by a processor in response to a determination that the period of time meets the time threshold to thereby resume monitoring of a health of the engine cooling system;
- and
- delaying the modeling of the expected coolant temperature of the engine cooling system to thereby delay the monitoring of the health of the engine cooling system in response to either a determination that the transient condition is the delay condition or a determination that the period of time does not meet the time threshold.
