ABSTRACT:
A hot coolant type heat accumulating apparatus for a hybrid vehicle is provided that includes an internal combustion engine having first and second coolant circulation systems through which a coolant is circulated using power from the engine, a heat accumulation tank that recovers, via part of the second coolant circulation system, some of the coolant that has been heated by the internal combustion engine, and stores that heated coolant, and a controller. This controller automatically shuts off the internal combustion engine when a predetermined shutoff condition has been fulfilled, circulates the coolant through the second coolant circulation system while the internal combustion engine is shutoff, and inhibits recovery of the hot coolant while the internal combustion engine is shutoff by automatic shutoff.
