PROBLEM TO BE SOLVED: To make an occupant hardly feel incongruity by avoiding an abrupt change of a sound volume of an operation sound in a cabin when largely lowering a drive duty such as a stop of an EOP 19 of a vehicle Ve.SOLUTION: It is determined whether or not the supply of oil by an EOP 19 is necessary (step ST1: determination part), and when it is determined that the supply of the oil is necessary, a drive duty is controlled to a first value, and on the other hand, when it is determined that the supply of the oil is not necessary, the drive duty is controlled to a second value which is smaller than the first value (steps ST2, ST5: duty control part). When performing duty variable control (YES at step ST4), the drive duty is controlled to a third value which is an intermediate value between both the first value and the second value during a prescribed changeover transition period in the middle of the changeover of the drive duty to the second value from the first value (steps ST8, ST9).SELECTED DRAWING: Figure 6

    【課題】車両VeのEOP19を停止させるときなど、駆動デューティを大幅に低下させるときに、車室内において動作音の音量が急変しないようにして、乗員が違和感を覚え難くする。【解決手段】EOP19によるオイルの供給が必要か否か判断し(ステップST1:判断部)、オイル供給が必要と判断すれば、駆動デューティを第1の値に制御する一方、オイル供給が必要でないと判断すれば、第1の値よりも小さな第2の値に制御する(ステップST2,ST5:デューティ制御部)。デューティ可変制御を行うときには(ステップST4でYES)、駆動デューティを第1の値から第2の値に切り替える途中で所定の切替遷移期間、両者の中間の第3の値に制御する(ステップST8,ST9)。【選択図】図6
