Abstract: An electrified vehicle system includes an electric motor coupled to a drive wheel via a plurality of power transmission components and a control device. The control device is configured to act as: a feedforward control section configured based on a transfer function simulating vibration transmission characteristics of a power transmission system, receiving as an input a required torque of the electric motor from a driver, and outputting a base command torque of the electric motor; a timing estimation section estimating, based on information on the power transmission system, a timing at which a backlash between the plurality of power transmission components is eliminated; and a torque correction section applying, to the base command torque, a correction torque for reducing a vibration generated in the power transmission system due to elimination of the backlash, in response to an arrival of the timing estimated by the timing estimation section.

Abstract: There is provided a vibration damper which is capable of damping torsional vibrations by pendulum movement of a plurality of inertial masses, and damping vibrations of plurality of order without letting the inertial masses to interfere.A distance between a center of curvature of an inner surface of a first through-hole and a center of curvature of an inner surface of a second through-hole formed in a rotary member is shorter than a distance between a center of curvature of an inner surface of a fifth through-hole and a center of curvature of an inner surface of a sixth through-hole formed in a first inertial mass. Moreover, a distance between a center of curvature of an inner surface of a third through-hole and a center of curvature of an inner surface of a fourth through-hole in a rotary member is longer than a distance between a center of curvature of an inner surface of a seventh through-hole and a center of curvature of an inner surface of an eighth through-hole formed in a second inertial mass.

Abstract: The battery includes a laminate including a battery cell and intermediate members disposed on both sides of the battery cell in the thickness direction. The battery cell includes an electrode lamination portion in which a plurality of electrodes is laminated in the thickness direction, and a seal portion disposed covering an outer edge of the electrode lamination portion. The intermediate members include a current collector plate portion and an elastic body portion. When the battery is viewed in plan from the thickness direction, the area of the current collector plate portion is smaller than the area of the battery cell, the current collector plate portion has a notch, and the elastic body portion is disposed in the notch, and the elastic body portion overlaps with the seal portion.

Abstract: A torsional vibration damper includes a planetary rotary unit and an elastic body that couples two rotary elements of three rotary elements so that the two rotary elements can rotate relatively to each other. The torsional vibration damper includes a shaft supporting member by which a rotation center axis of at least any one rotary element of the two rotary elements and a rotation center axis of the rotary element other than the planetary rotary unit and the two rotary elements are held on the same axis. The shaft supporting member has a holding section that is disposed in a position between fellow planetary rotary elements and not making contact with the planetary rotary elements and that fits with and thereby suppresses movement of the rotary element other than the planetary rotary unit and the two rotary elements in the axial direction.

Abstract: A torsional vibration damper in which a mass may be fitted easily into a chamber is provided. In the rotary disc, an insertion hole is formed integrally with the chamber. An opening diameter of the insertion hole is larger than an outer diameter of a flange plate of the mass, and an opening width at a boundary between the insertion hole and the chamber is larger than an outer diameter of a trunk of the mass. The retainer comprises a restricting portion that restricts an oscillating range of the mass in the chamber.
