摘要： Provided is a vibration damping device including guide surfaces that are concave surfaces formed in a support member so as to curve toward the outer periphery of the support member; mass bodies that, as the support member rotates, roll on the guide surfaces while being pressed against the guide surfaces by a centrifugal force; and inertia rings that are rotatably coupled to the mass bodies and swing about the center of rotation of the support member. When the vibration damping device is in equilibrium, the center of gravity of each mass body is located radially outward of the joint position between the mass body and the inertia rings. As the support member rotates, the inertia rings swing relative to the support member about the center of rotation of the support member, and the mass bodies roll on the guide surfaces.

摘要： A control device for performing start assist control for an internal combustion engine includes: a first start assist processing unit that executes a first start assist process that brings a first engagement device into slip engagement at a first engagement pressure while increasing a torque generated by a rotating electrical machine; and a second start assist processing unit that increases, when the first start assist process fails to start the internal combustion engine, an engagement pressure of the first engagement device to a second engagement pressure higher than the first engagement pressure while increasing the torque generated by the rotating electrical machine. The second start assist processing unit determines the second engagement pressure on the basis of a rotational speed of the internal combustion engine in the first start assist process.

摘要： A damper device includes first inner springs configured to transmit a torque between a drive member and an intermediate member, second inner springs configured to transmit a torque between the intermediate member and a driven member, and a rotary inertia mass damper including a sun gear serving as a mass body rotating with relative rotation of the drive member to the driven member. The rotary inertia mass damper is provided in parallel to a torque transmission path including the intermediate member, the first inner springs and the second inner springs. A damping ratio ζ of the intermediate member determined based on a moment of inertia J2 of the intermediate member and rigidities k1 and k2 of the first and the second inner springs and is less than a value.
