1. A control device for a vehicle, the vehicle including
an internal combustion engine, a driving wheel, a continuously variable transmission including a first input shaft and a first output shaft, the first input shaft being rotationally driven by the internal combustion engine, the continuously variable transmission being configured to continuously change a first gear ratio, and the first gear ratio being a ratio of a rotation speed of the first input shaft to a rotation speed of the first output shaft, and a stepped variable transmission including a second input shaft and a second output shaft, the second input shaft being connected to the first output shaft, the second output shaft being connected to the driving wheel, and the second output shaft being configured to transmit torque to the driving wheel, the stepped variable transmission being configured to change a second gear ratio in a stepwise manner, and the second gear ratio being a ratio of a rotation speed of the second input shaft to a rotation speed of the second output shaft, and the control device comprising: an electronic control unit configured to (i) control a rotation speed of the internal combustion engine in a period during which the vehicle is accelerated according to an acceleration request to the vehicle such that the rotation speed of the internal combustion engine is increased with an increase in a traveling speed of the vehicle, (ii) when the rotation speed of the internal combustion engine reaches a predetermined pseudo gear shift threshold value, execute a pseudo gear shift to control the rotation speed of the internal combustion engine such that the rotation speed of the internal combustion engine is decreased to a first rotation speed, (iii) execute a mechanical gear shift to change the second gear ratio according to a gear shift line determined by the traveling speed and a value according to the acceleration request, and (iv) execute adjustment control to adjust the rotation speed of the internal combustion engine in advance in a period before executing the mechanical gear shift such that the rotation speed of the internal combustion engine matches the pseudo gear shift threshold value when the mechanical gear shift is performed. |
