PROBLEM TO BE SOLVED: To provide a cooling system of a motor-mounted automobile which can suppress power consumption by driving of a cooling pump as much as possible without giving a harmful effect to travel.SOLUTION: A drive start control part 21, in which a shift position is in a travel range at the time of stop of a cooling pump 7 and which starts drive of the cooling pump 7 when a sign of determined travel start is detected, is provided. Further, a stop control part 22, which stops drive of the cooling pump 7 when the shift position is in non-travel range or a sign of travel stop is detected at the time of driving of the cooling pump 7, is provided. In the case that the cooling pump 7 is variable in a flow rate, the cooling pump 7 may be driven for the time being at a low speed or a medium speed when the shift position is in the travel range at the time of stop of the cooling pump 7, and the pump may be driven at a high speed when the sign of travel start is detected.SELECTED DRAWING: Figure 1

    【課題】走行に悪影響を与えることなく、冷却ポンプの駆動による電力消費をできるだけ抑えることができるモータ搭載自動車の冷却システムを提供する。【解決手段】冷却ポンプ7の停止時に、シフトポジションが走行レンジであり、かつ定められた走行開始の予兆が検出されると前記冷却ポンプ7の駆動を開始させる駆動開始制御部21を設ける。また、冷却ポンプ7の駆動時に、シフトポジションが走行レンジ以外であるか、または走行停止の予兆が検出されると冷却ポンプ7の駆動を停止させる停止制御部22を設ける。冷却ポンプ7が流速可変の場合は、冷却ポンプ7の停止時にシフトポジションが走行レンジであると、取合えず低速または中速で冷却ポンプ7を駆動させ、走行開始の予兆が検出されると高速駆動を行うようにしても良い。【選択図】図1
