Abstract:
1. A hybrid vehicle, comprising: an engine operating on fuel combustion; power generating means capable of generating electric power, receiving power generated by the operation of said engine; a power storage unit charged by the electric power from said power generating means; driving force generating means for generating driving force from the electric power from at least one of said power generating means and said power storage unit; external charging means electrically connected to an external power supply, for charging said power storage unit by said external power supply; and a control unit for controlling vehicle driving force to be generated in accordance with a driver's request, and for controlling electric power charged/discharged at said power storage unit; wherein said control unit controls in a first running mode until a value of state of charge of said power storage unit attains lower than a prescribed value, and makes a transition to a second running mode when said value of state of charge becomes lower than the prescribed value; in said first running mode, charging of said power storage unit by said power generating means is limited, and in said second running mode, charging of said power storage unit by said power generating means is allowed such that said value of state of charge is maintained in a prescribed range with a control center value being the center; and said control unit includes control center value changing means for changing said control center value in accordance with an external charge execution degree as a degree of executing charging of said power storage unit by said external charging means.
