To provide a vehicle motor cooling device capable of preventing a temperature of a motor from exceeding an allowable temperature even when the temperature of the motor rapidly increases.SOLUTION: A vehicle motor cooling device 10 which cools a motor 11 driving a vehicle comprises: a cooling circuit 12 which cools the motor 11 with cooling oil; a pump 13 which circulates the cooling oil in the cooling circuit 12; a motor temperature sensor 15 which detects a temperature of the motor 11; an accelerator pedal 14 which is operated by a driver of a vehicle; an accelerator opening sensor 16 which detects an accelerator opening of the accelerator pedal 14; and a pump control section 17 which controls output of the pump 13 in accordance with the temperature of the motor. The pump control section 17 increases the output of the pump 13 when the accelerator opening is equal to or larger than a predetermined value.SELECTED DRAWING: Figure 1

    【課題】モータ温度が急激に上昇した場合であってもモータ温度が許容温度を超えることを防止することができる車両用モータ冷却装置を提供する。【解決手段】車両を駆動するモータ11を冷却する車両用モータ冷却装置10であって、モータ11を冷却オイルによって冷却する冷却回路12と、冷却回路12の冷却オイルを循環させるポンプ13と、モータ11の温度を検出するモータ温度センサー15と、車両の運転者によって操作されるアクセルペダル14と、アクセルペダル14のアクセル開度を検出するアクセル開度センサー16と、モータ温度に応じてポンプ13の出力を制御するポンプ制御部17と、を備え、ポンプ制御部17は、アクセル開度が所定値以上の場合には、ポンプ13の出力を増加させる。【選択図】図1
