To control the amount of oil supplied to a catch tank.SOLUTION: A cooling device is mounted on a series hybrid vehicle including an engine, a motor for power generation, a gear pair for transmitting the power of the engine to the motor for power generation, a catch tank for storing oil scraped up by the gear pair, and a control device for controlling the engine, and cools the motor for power generation using oil stored in the catch tank, wherein the gear pair is arranged at a position where an input gear on an engine side is immersed in the oil in rotation stop, the input shaft rotated integrally with the input gear is arranged at a position lower than the rotary shaft of the motor, and when the amount of the oil stored in the catch tank is small, the control device changes the operation point of the engine so that the engine rotation number is increased on a power line where the engine rotation number in which the output of the engine becomes constant and an engine torque are regulated.SELECTED DRAWING: Figure 2

    【課題】キャッチタンクに供給するオイルの量を制御すること。【解決手段】エンジンと、発電用モータと、エンジンの動力を発電用モータに伝達するギヤ対と、ギヤ対によって掻き上げられたオイルを貯留するキャッチタンクと、エンジンを制御する制御装置と、を備えるシリーズハイブリッド車に搭載され、キャッチタンクに貯留されたオイルを用いて発電用モータを冷却する冷却装置であって、ギヤ対は、エンジン側の入力ギヤが回転停止時にオイルに浸かる位置に配置され、入力ギヤと一体回転する入力軸は、モータの回転軸よりも低い位置に配置され、制御装置は、キャッチタンクに貯留されたオイルの量が少ない場合、エンジンの出力が一定となるエンジン回転数とエンジントルクとを規定する等パワー線上において、エンジン回転数が上がるようにエンジンの動作点を変更する。【選択図】図2
