  • Publication number: 20210024052
    Abstract: A control system includes a motor-generator, an electric power generation system, and a battery. An EV operation, in which the electric motor is operated while the electric power generation system is stopped, is performed, when an SOC of the battery is higher than a first value, and an HV operation, in which the electric motor is operated while the electric power generation system is operated, is performed, when the SOC is lower than the first value. At the time of the EV operation, in response to a predicted value of the SOC being equal to or higher than a second set value which is lower than the first set value, the EV operation is continued even if the SOC falls below the first value. The predicted value is a predicted value of the SOC assuming continuation of the EV operation from a current location to a destination.
