To adequately suppress heating performance degradation due to temperature drop of cooling water in a heater core.SOLUTION: A vehicle heating system comprises: a water-cooling type internal combustion engine; a cooling water path for circulating cooling water to be supplied to the internal combustion engine; a heater core which is provided on the cooling water path, performs heat exchange between cooling water, which flows out from the internal combustion engine, and air, and heats the interior of a cabin; a cooling water pump which is operated by reception of supply of a rotation driving force from the internal combustion engine, sucks and discharges cooling water which is circulated in the internal combustion engine, the cooling water path and the heater core; an electric motor which can rotationally drives the internal combustion engine; and a control part which, during a period in which operation of the internal combustion engine is stopped without combustion of a fuel, starts the electric motor according to a request for heating performance thereby rotationally driving the internal combustion engine, and operates the cooling water pump thereby flowing cooling water into the heater core from the internal combustion engine.SELECTED DRAWING: Figure 3

    【課題】ヒータコア内の冷却水の温度降下による暖房性能の低下を適切に抑制する。【解決手段】水冷式の内燃機関と、内燃機関に供給するべき冷却水を循環させる冷却水路と、冷却水路上に設けられ内燃機関から流出する冷却水と空気との間で熱交換を行い車室内を暖房するヒータコアと、内燃機関から回転駆動力の供給を受けて稼働し内燃機関、冷却水路及びヒータコアを流通する冷却水を吸引して吐出する冷却水ポンプと、内燃機関を回転駆動することのできる電動機と、燃料を燃焼させずに内燃機関の運転を停止している時期において、暖房性能の要求に応じて、電動機を起動して内燃機関を回転駆動し冷却水ポンプを稼働させて内燃機関からヒータコアに冷却水を流入させる制御部とを具備する車両の暖房システムを構成した。【選択図】図3
