Patent ID: 8612092

Claim:
A vehicle heat source control device configured to control heat supply from a plurality of heat sources equipped in a vehicle to a heat exchange part, the vehicle heat source control device comprising: a request heat power calculation unit configured to calculate a request heat power, which is requested to the plurality of heat sources to supply to the heat exchange part; a heat cost calculation unit configured to calculate a relationship between a heat power supplied from each of the plurality of heat sources and a heat cost being a fuel quantity consumed to supply a unit heat power; an abnormal heat source detection unit configured to detect an abnormal heat source, which is incapable of normally supplying a heat power, from the plurality of heat sources; an abnormal heat power calculation unit configured to calculate an abnormal heat power, which is a heat power supplied from the abnormal heat source; and a heat distribution determination unit configured to determine distribution of heat power supplied from the plurality of heat sources based on both: the relationship between the heat power supplied from each of the plurality of heat sources and the heat cost; and the abnormal heat power, such that: a sum total of the heat power supplied from the plurality of heat sources coincides with the request heat power; and the heat cost of all of the plurality of heat sources to supply the heat power is minimized.
