Coolant pump and valve prognostic strategy

A vehicle comprising:

• a refrigerant thermal management system that is configured to compress and expand refrigerant to heat and/or cool coolant utilizing one or more heat exchangers;
• a coolant distribution system including a plurality of pumps that are driven utilizing electrical power and valves that are configured to control coolant flow, whereby the coolant distribution system selectively heats and/or cools a vehicle cabin and/or vehicle components;
• wherein the vehicle is configured to:
• measure pump operating parameters associated with the pumps during operation of the coolant distribution system, wherein the pump operating parameters comprise the electricity consumption of each pump and a temperature of coolant flowing through a coolant loop associated with each pump;
• measure valve operating parameters associated with the valves during operation of the coolant distribution system, wherein the valve operating parameters comprise a valve response time, a valve position, and a temperature of coolant flowing through a coolant loop associated with each valve;
• utilize the measured pump operating parameters and the measured valve operating parameters to repeatedly update metrics that model the states of the pumps and valves;
• detect anomalies by comparing the updated metrics to the expected metrics, wherein the expected metrics correspond to pumps and valves having acceptable operation according to predefined degradation criteria;
• and
• provide an alert concerning impending operating issues based, at least in part, on detected anomalies and/or a predicted remaining useful life (RUL) of the pumps and valves wherein the predicted RUL is based, at least in part, on detected anomalies.
