Patent ID: 8397850

Claim:
A driving system of a hybrid electric vehicle comprising: a generator to generate electric energy from rotating power input thereto; an electric motor to generate rotating power from electric energy supplied thereto; a power distributor to distribute the rotating power, so as to provide the generator with a part of the rotating power; a control unit to control distribution of the rotating power by controlling the supply of electric current to the power distributor; and an auxiliary drive wheel movably installed to be raised or lowered, the auxiliary drive wheel when lowered, being rotated in contact with a ground surface to provide the generator with rotating power generated upon rotation of the auxiliary drive wheel, wherein the generator transmits the rotating power, generated by the auxiliary drive wheel, to the power distributor, and wherein the power distributor combines the rotating power generated by the auxiliary drive wheel with the rotating power generated by the electric motor, to rotate a drive wheel using the combined rotating power.
