Abstract
A control device (100) for a vehicle (1): performs virtual gear-shifting control for controlling the engine speed to a first speed, which corresponds to the vehicle speed and a plurality of virtual gear-shifting lines, when clutches (CL1, CL2) are set to a disengaged state and the vehicle (1) travels under motor (MOT) power; and controls the engine speed to a second speed, which corresponds to the vehicle speed, when the clutches (CL1, CL2) are set to an engaged state and the vehicle 1 travels under engine (ENG) power. Each of the plurality of virtual gear-shifting lines defines the engine speed respectively corresponding to the vehicle speed, and the relationship between the vehicle speed and the engine speed when the clutches (CL1, CL2) are in an engaged state is located on the same speed line coinciding with the relationship between the vehicle speed and the engine speed in any of the virtual gear-shifting lines among the plurality of virtual gear-shifting lines.
