Patent ID: 8583309

Claim:
A hybrid vehicle, comprising: an internal combustion engine; a generator that inputs and outputs power from and to an output shaft of the internal combustion engine, rotates at an rotation speed corresponding to an rotation speed of the internal combustion engine, and generates back electromotive force with rotation; a generator inverter circuit that drives the generator; a motor that inputs and outputs power from and to an axle; a motor inverter circuit that drives the motor; a secondary battery that transmits electric power to and from the generator and the motor via the generator inverter circuit and the motor inverter circuit; an accumulated charge ratio detecting module that detects an accumulated charge ratio as a ratio of an accumulated charge amount to whole capacity of the secondary battery; and a control module that, upon satisfaction of a predetermined condition that the detected accumulated charge ratio is less than or equal to a predetermined accumulated charge ratio in a state that a gearshift position is a neutral position and both of the generator inverter circuit and the motor inverter circuit are shut off, controls the internal combustion engine and the generator so that the internal combustion engine is cranked by the generator and started in a case that the vehicle stop is held, and controls the generator inverter circuit to be shut off and the internal combustion engine to be operated at a rotation speed that the back electromotive force generated with the rotation of the generator is more than a voltage applied to the generator inverter circuit after the internal combustion engine is started.
