Vehicle control device

A vehicle control device that controls a vehicle, the vehicle comprising an internal combustion engine, a generator driven by the internal combustion engine, and an electric motor coupled to a drive wheel and capable of driving the drive wheel by being supplied with electric power from the generator, and the vehicle being capable of series traveling in which electric power generated by the generator is supplied to the electric motor and the electric motor drives the drive wheel to cause the vehicle to travel,

• wherein the vehicle control device is configured to:
• execute fuel cut control for stopping fuel supply to the internal combustion engine;
• when the vehicle is in the series traveling, perform control based on a traveling state of the vehicle such that a rotation speed of the internal combustion engine is a predetermined target rotation speed;
• when the vehicle is in the series traveling and is accelerating, perform pseudo-shift control in which the rotation speed of the internal combustion engine is increased to a first target rotation speed, and in a case where the first target rotation speed is reached, the rotation speed of the internal combustion engine is reduced to a second target rotation speed lower than the first target rotation speed;
• and
• when the vehicle is in the series traveling and there is a deceleration request during the pseudo-shift control, execute the fuel cut control in accordance with a rotation speed difference between the rotation speed of the internal combustion engine and the target rotation speed.
