Abstract
In a control method of a vehicle, an electric power consumption, which is an electric power consumed by the motoring, includes a friction electric power consumption, which is an electric power consumption of the motoring determined according to friction of the internal combustion engine, and an inertia electric power, which is an electric power consumed for an inertia torque for changing a rotation speed of the internal combustion engine.

A method for controlling a series hybrid vehicle having a first forward range and a second forward range, the method comprising:
- driving drive wheels by a traveling motor using an electric power generated by an electric power generation motor that is driven with a power of an internal combustion engine;
- performing motoring of the internal combustion engine by the electric power generation motor when a regenerative electric power exceeding an acceptable electric power of a battery is generated by the traveling motor;
- and
- performing regenerative deceleration with a total electric power of an electric power consumed by the motoring and the acceptable electric power of the battery as an upper limit, wherein
- the electric power consumed by the motoring includes an electric power consumption of the motoring determined according to friction of the internal combustion engine and an inertia electric power that is an electric power consumed for an inertia torque for changing a rotation speed of the internal combustion engine, and
- when a change in a target rotation speed of the motoring is larger than a predetermined value, the inertia electric power is not included in the electric power consumed by the motoring.
