The control method for the hybrid vehicle includes a rotation speed control torque calculation step of, based on a rotation speed command value for the electric generator and a rotation speed detection value of the electric generator, calculating a torque command value for controlling the rotation speed of the electric generator, and an electric generator control step of controlling the electric generator according to the torque command value. The rotation speed control torque calculation step calculates, using the model matching compensator and based on a value obtained by filtering the rotation speed detection value through the low-pass filter and the rotation speed command value, a basic torque command value that makes a torque response of the electric generator coincide with a preset model response, calculates, using the disturbance observer including the transfer function composed of the inverse system of the control object model patterned after a power transmission system of the electric generator connected to the engine via the gears and a disturbance observer filter, and based on the rotation speed detection value, a disturbance torque that is input into the power transmission system, and calculates the torque command value based on the basic torque command value and the disturbance torque. The relative degree of the disturbance observer filter is set so that the relative degree of the transfer function becomes 1 or more.
