  • Patent number: 10994619
    Abstract: A control method for an electric vehicle includes controlling a torque of a motor based on a final torque command value by calculating the final torque command value such that a vibration damping control to reduce vibrations of a driving force transmission system of a vehicle is performed on a target torque command value set based on vehicle information, calculating the final torque command value based on the target torque command value and a value obtained by multiplying a drive-shaft torsional angular velocity by a feedback gain, estimating, by use of a vehicle model that models the driving force transmission system, a dead-zone period during which a motor torque output from the motor is not transmitted to a drive-shaft torque of the vehicle, and determining whether or not the vehicle is just before stop of the vehicle.

  • Patent number: 8087556
    Abstract: An electric driver includes a hook portion which is constituted by a deformable hook-like portion and a connecting portion for connecting the hook-like portion to the handle. The hook-like portion is constituted by a base portion connected to the connecting portion and a bent portion continuous to the base portion, and a front end portion continuous to the bent portion and arranged at a position substantially opposed to the base portion. The front end portion and the base portion can be proximate to and remote from each other. The connecting portion holds the hook-like portion in a direction substantially the same as a direction in which the handle extends. The hook-like portion is pivotably held on a first rotating axis center extending in substantially the same direction as the handle.

  • Patent number: 7431187
    Abstract: A wrenching portion provided in an adjuster and employed for assembling is formed at a gripping portion for rotation. The gripping portion is formed in a polygonal shape. In this configuration, the adjuster is decreased in size and weight and its operability of adjusting a driving depth is improved. An undercut portion is removed in a vertical direction and a non-slip rugged portion is provided in only a longitudinal direction so that it can be manufactured in a simple tow-part mold, thereby reducing the production cost.
