Claim:
1. A vehicle comprising: an internal combustion engine configured to generate power for rotating drive wheels; a differential mechanism provided between the internal combustion engine and the drive wheels, and the differential mechanism having at least three rotary elements including a first rotary element coupled to the internal combustion engine and a second rotary element coupled to the drive wheels; and a controller configured to control the internal combustion engine, the controller being configured to determine whether to perform correction to increase the power generated by the internal combustion engine or perform correction to reduce the power generated by the internal combustion engine, depending on a rotational speed of the second rotary element, when the controller changes a rotational speed of the internal combustion engine, wherein: there is a positive correlation between a rotational speed of the first rotary element and rotational energy of the differential mechanism, in a first region in which the rotational speed of the second rotary element is lower than a boundary value determined according to the rotational speed of the first rotary element; there is a negative correlation between the rotational speed of the first rotary element and rotational energy of the differential mechanism, in a second region in which the rotational speed of the second rotary element is higher than the boundary value; and the controller increases the rotational speed of the internal combustion engine by performing correction to increase the power generated when the rotational speed of the second rotary element is included in the first region, and the controller increases the rotational speed of the internal combustion engine by performing correction to reduce the power generated when the rotational speed of the second rotary element is included in the second region; and the controller reduces the rotational speed of the internal combustion engine by performing correction to reduce the power generated when the rotational speed of the second rotary element is included in the first region, and the controller reduces the rotational speed of the internal combustion engine by performing correction to increase the power generated when the rotational speed of the second rotary element is included in the second region.
