Abstract: When an estimated charging rate of an electric storage device is lower than a target rate, and a regenerative power generation controller performs power-generation control of an electric power generator when the speed of a vehicle is being reduced and fuel supply to an engine is stopped, a regenerative charging amount predictor predicts a regenerative charging rate in accordance with vehicle speed, as the vehicle speed is being reduced, and the target charging rate of the electric storage device is decreased as the regenerative predicted charging amount increases. The regenerative power generation controller limits a power-generation amount toward reduction in such a way that in the electric power generator, a difference between torque required for power generation when the electric storage device is charged and torque required for power generation when the electric storage device is not charged falls within a predetermined torque difference.
