Control system for vehicle

A control system for a vehicle, comprising:

• an electric motor connected to a vehicle axle to be able to transmit power;
• an electric power generation system;
• a battery configured to supply electric power to the electric motor and to be able to be charged from the electric power generation system and from the outside of the vehicle;
• and
• an electronic control unit configured to perform an electric vehicle (EV) operation, in which the electric motor is operated while the electric power generation system is stopped, when a state of charge (SOC) of the battery is higher than a predetermined, first set value, and to perform a hybrid vehicle (HV) operation, in which the electric motor is operated while the electric power generation system is operated, when the SOC of the battery is lower than the first set value,
• wherein the electronic control unit is further configured to:
• continue the EV operation even if the SOC of the battery falls below the first set value when, at the time of the EV operation, it is judged that an electric vehicle state of charge (EVSOC) predicted value is maintained equal to or higher than a second set value which is lower than the first set value, the EVSOC predicted value being a predicted value of the SOC of the battery when assuming continuation of the EV operation from the current location to the destination,
• continue, when it is judged that the EVSOC predicted value will fall below the second set value, the EV operation until the vehicle passes a third position between a first position and a second position and to switch from the EV operation to the HV operation if the vehicle passes the third position, the first position being a position where the EVSOC predicted value falls below the first set value and the second position being a position where the EVSOC predicted value falls below the second set value;
• and
• set the third position so that a hybrid vehicle state of charge (HVSOC) predicted value is maintained equal to or higher than the second set value, the HVSOC predicted value being a predicted value of the SOC of the battery when assuming continuing the EV operation from the current location, then switching from the EV operation to the HV operation if the vehicle passes the third position, and then continuing the HV operation until the destination.
