  • Patent number: 9308830
    Abstract: An electric vehicle comprises: a battery installed under a floor panel; an electrical component unit installed above the floor panel and behind the battery; an electric power supply harness connecting the electrical component unit and the battery; and a motor driven by electric power from the battery. A mounting portion where the harness is mounted is provided on a bottom surface of the electrical component unit. The mounting portion faces an opening of the floor panel, and the mounting portion has a fixing portion on the front side thereof in the longitudinal direction of the vehicle, the fixing portion allowing the harness to be fixed thereto in such a manner as to be routed toward the front of the vehicle. An inclined surface inclined downwardly toward the front of the vehicle is provided on the back side of the mounting portion in the longitudinal direction of the vehicle.

  • Patent number: 9211810
    Abstract: A vehicle control apparatus includes a PHEV-ECU containing a measuring unit which measures the amount of torsional stress on the front drive shafts in a parking lock state and a control unit which controls the torque of the front motor. When the parking lock state is released, the torque acting as a load on the rotation of the first motor upon the release of the torsional stress on the drive shaft, is determined based on the torsional stress measured. Further, the front motor is controlled to output the determined torque.

  • Patent number: 9174551
    Abstract: A drive device for an electric vehicle includes: a parking lock mechanism that mechanically locks a rotation of a rotating shaft of drive wheels; a parking lock operating unit; an electric motor; a balancing torque estimating unit for applying rotational torque to the electric motor in the opposite direction of the direction of torsional torque applied to the rotating shaft, while locking via the parking lock mechanism is done, and for balancing torque in advance that balances out the torsional torque, based on a state of the rotational phase of the electric motor; and a torque applying unit for applying torque to the electric motor before the locking is released, the torque calculated based on the estimated balancing torque.

  • Patent number: 8448542
    Abstract: A front-and-rear-wheel-drive vehicle includes first and second electric drive motors which drive front and rear wheels, the second electric drive motor has a maximum torque greater than that of the first electric drive motor, a first speed reducer which reduces rotation of the first electric drive motor, a second speed reducer which reduces rotation of the second electric drive motor at a speed reduction ratio smaller than that of the first speed reducer, the speed reduction ratios of the first and second speed reducers are set in a manner that a maximum rate of rotation of one of the front and rear wheels corresponding to that of the second electric drive motor is greater than a maximum rate of rotation of the other wheel corresponding to that of the first electric drive motor.
