Abstract
This is a control method for a vehicle, the vehicle including an electric generator, an engine coupled to the electric generator, a drive motor configured to drive the vehicle, and a battery electrically connected to the electric generator and the drive motor, electric power generated by the electric generator being configured to be supplied to at least one of the battery and the drive motor. The control method is including: calculating, when a temperature of the battery is equal to or lower than a predetermined temperature, a drive torque target value based on required electric power of the vehicle and a state of the battery, controlling a torque of the electric generator based on the drive torque target value, and controlling a rotation speed of the engine based on a predetermined reference low rotation speed, thereby performing a low electric power generation control for causing the electric generator to generate electric power.
