Patent ID: 7610974

Claim:
A hybrid vehicle, comprising: an internal combustion engine that is rotatable independently of a driving state of said hybrid vehicle; a rotational resistance adjustment structure that adjusts a rotational resistance of the internal combustion engine; an engine-starting motor that is driven for motoring of the internal combustion engine; an accumulator unit that is chargeable and dischargeable; a driving motor that has power generation capability and inputs and outputs driving power through transmission of electric power to and from at least one of the engine-starting motor and the accumulator unit; and an accelerator-brake-released state control module that, when the accumulator unit is in an unchargeable state at a timing of a braking force demand by release of both an accelerator and a brake, controls the rotational resistance adjustment structure to adjust the rotational resistance of the internal combustion engine according to the braking force demand, controls the driving motor to drive said hybrid vehicle with a braking force equivalent to the braking force demand and to generate regenerative electric power, and controls the engine-starting motor to consume the regenerative electric power generated by the driving motor by having the engine-starting motor operate to motor the internal combustion engine.
