PROBLEM TO BE SOLVED: To make operating sound of an electric oil pump to be hardly recognized as noise by a driver and passengers while suppressing electric power consumption by the electric oil pump.SOLUTION: A control device for a vehicle comprises: a power transmission path connecting an engine 11 and a motor 12 for traveling to drive wheels 21; a mechanical pump 41 driven by drive systems 51, 69 which are connected to the power transmission path; an electric pump 72 driven by an electric motor 71; and a control unit 73 for varying rotation speed of the electric pump 72 according to a change of the vehicle speed. The control unit 73, when a change rate of the vehicle speed rises, raises a change rate of the rotation speed of the electric pump 72 and, when the change rate of the vehicle speed lowers, lowers the change rate of the rotation speed of the electric pump 72. |
