Control device for vehicle

A control device for a vehicle including an engine and a stepless gear shifting mechanism that is able to adjust a rotation speed of the engine, the control device controlling the engine and the stepless gear shifting mechanism such that an operating point of the engine reaches an operating point in a predetermined optimal fuel-efficiency operating line, the control device comprising:

• a prediction unit configured to predict a noise generation duration time in which the operating point of the engine will stay in a noise generation region in which noise is generated in the optimal fuel-efficiency operating line when the operating point of the engine reaches an operating point in the noise generation region at the time of controlling the engine and the stepless gear shifting mechanism such that the operating point of the engine reaches an operating point in the optimal fuel-efficiency operating line;
• and
• a control unit configured to control the engine and the stepless gear shifting mechanism such that the operating point of the engine reaches an operating point in the optimal fuel-efficiency operating line when the noise generation duration time predicted by the prediction unit is equal to or less than a predetermined time which is determined in advance and to control the engine and the stepless gear shifting mechanism such that the operating point of the engine reaches an operating point at which generation of noise is curbed and which is outside of an operating point in the optimal fuel-efficiency operating line when the noise generation duration time predicted by the prediction unit is greater than the predetermined time.
