To provide a control arrangement of a cooler for vehicle capable of restraining increase in the oil surface height of oil in an oil reservoir section while the vehicle is running.SOLUTION: When an electric oil pump 36 is driven, an electromagnetic on-off valve 38 is switched to closed state, thereby the oil discharged from a mechanical oil pump 34 is supplied to a MOP oil passage 40, and the oil discharged from the electric oil pump 36 is supplied to a motor cooling oil passage 44 via an EOP oil passage 42. When the electric oil pump 36 is stopped, the electromagnetic on-off valve 38 is switched to open state, thereby the oil discharged from the mechanical oil pump 34 is supplied to the motor cooling oil passage 44 via the MOP oil passage 40 and the EOP oil passage 42. With such an arrangement, the MOP oil passage 40, the EOP oil passage 42 and the motor cooling oil passage 44 can be filled with oil even when the electric oil pump 36 is driven or stopped, and increase in the oil surface height of the oil reservoir section can be restrained while the vehicle is running.SELECTED DRAWING: Figure 1

    【課題】車両走行中にオイル貯留部のオイルの油面高さの上昇を抑制することができる車両用冷却装置の制御装置を提供する。【解決手段】電動オイルポンプ36が駆動される場合には、電磁開閉弁38が閉状態に切り替えられるので、機械式オイルポンプ34から吐出されるオイルがMOP油路40に供給されると共に、電動オイルポンプ36から吐出されるオイルがEOP油路42を介して電動機冷却油路44に供給される。電動オイルポンプ36が停止すると、電磁開閉弁38が開状態に切り替えられるので、機械式オイルポンプ34から吐出されるオイルがMOP油路40およびEOP油路42を介して電動機冷却油路44に供給される。このため、電動オイルポンプ36が駆動される場合または停止する場合であってもMOP油路40とEOP油路42と電動機冷却油路44とをオイルで満たすことができ車両走行中にオイル貯留部の油面高さの上昇を抑制できる。【選択図】図1
