Abstract
A method for controlling coolant flow and cooling of a heater core to be used as a cold storage device or “heater core cold storage” (HCCS) cooling of a vehicle to extend an engine auto-stop period includes determining if at least one predetermined condition is met for HCCS cooling, and charging a heater core for a predetermined charge period in preparation for HCCS cooling when the at least one predetermined condition is met. The charge is held in the heater core until a trigger event occurs and HCCS cooling is initiated. HCCS cooling is then performed until a predetermined use period expires.
