Patent ID: 6851502

Claim:
A differential mechanism for a vehicle comprising: a differential for transferring a rotational drive force of an input shaft to two output shafts so as to permit a difference in a rotating speed between the two output shafts, the input shaft being connected to a power source; an input generator motor for generating an electric power by using a rotational drive force of the input shaft and/or applying a rotational drive force to the input shaft by using the electric power supplied thereto; an output generator motor for generating the electric power by using the rotational drive force of one of the output shafts and applying the rotational drive force to the one of the output shafts by using electric power supplied thereto; connecting means for electrically connecting the input generator motor with the output generator motor; and, a switching control unit for switching between an output drive force control for supplying the electric power generated by the input generator motor to the output generator motor and an input drive force control for supplying the electric power generated by the output generator motor to the input generator motor.
