<P>PROBLEM TO BE SOLVED: To provide a vehicular motor driving apparatus that can reduce wasteful heat of an electric motor and rotate the electric motor even when travelling resistance torque exceeds generated torque of the electric motor. <P>SOLUTION: The vehicular motor driving apparatus can reduce the wasteful heat of the electric motor 22 by actuating a clutch function of a torque limitter device 56, interrupting a power transmission passage between the electric motor 22 and a rear wheel 26, and idling the electric motor 22, when a drive torque Tm of the electric motor 22 reaches a torque limitter value Tlim of the torque limitter device 56, and moreover, can collect energy by converging the idled electric motor 22 into rotation energy of a flywheel 68 and accumulating it. <P>COPYRIGHT: (C)2011,JPO&INPIT |
