Abstract
When a noise generation duration time predicted by a prediction unit is equal to or less than a predetermined time and it is predicted that generation of noise can be further curbed in comparison with a case in which the noise generation duration time in which noise is generated is relatively short and the noise generation duration time is greater than the predetermined time, an engine operating point control unit controls an engine and a differential unit such that an engine operating point reaches an engine operating point in an optimal fuel-efficiency operating line and thus it is possible to curb generation of noise and to curb a decrease in fuel efficiency.
