Beschreibung
Zusammenfassung:	A heat distribution device for hybrid vehicle is provided, including: an engine cooling circuit through which cooling water for cooling an internal combustion engine circulates; a MG cooling circuit through which a refrigerant for cooling a motor generator circulates; and a heat exchanger which performs heat exchange between the cooling water and the refrigerant. When it is determined based on a charging rate SOC of a battery that the battery can be charged, charging control is performed to charge the battery with electric power generated in a regenerative operation; when it is determined that the battery cannot be charged, heat dissipation control is performed to dissipate the heat generated by the regenerative operation to the engine cooling circuit side by the heat exchange between the refrigerant and the cooling water in the heat exchanger.
