PROBLEM TO BE SOLVED: To provide a drive unit which can suppress rise delay of a fluid transfer amount and a fluid pressure while suppressing erroneous control caused by noise, in a motor of a vehicle electric pump.SOLUTION: In a drive unit which sets a target value Ntr according to an instruction value Nin of a control amount, and controls a motor of a vehicle electric pump on the basis of the target value Ntr, when the instruction value Nin is higher than an actual value Nac of the control amount, the drive unit sets the instruction value Nin as the target value Ntr. When the instruction value Nin is lower than the actual value Nac, the drive unit sets the actual value Nac as the target value Ntr if the actual value Nac is smaller than a value smaller than the previous target value Ntr by a prescribed value &Dgr;&thetas;, and sets the value smaller than the previous target value Ntr by the prescribed value &Dgr;&thetas; as the target value Ntr if the actual value Nac is larger than the value smaller than the previous target value Ntr by the prescribed value &Dgr;&thetas;. |
