Control device, powertrain, method and program for reducing noise generation in powertrain and / or increasing mass inertia at idling speed

摘要

To improve the compromise between comfort, responsiveness and economic and ecological forms of a vehicle powertrain. A powertrain includes a drive prime mover, a starting element, and a clutch element. The starting element includes a mass damper torsion damper having a mass damper mass, and the starting element is disposed on a primary side thereof. 130 and the secondary side 150 are connected to the driving prime mover 110 and the mass damper shock absorber 160 in a relatively non-rotatable manner, respectively, and a clutch element 210 is formed to brake the secondary side by connection with the primary side 130 of the starting element 120. In the control device, the control device 200 is configured to operate the clutch element 210. Therefore, when the control device 200 receives an input signal indicating that the drive motor 110 is turned off, the clutch element 210 brakes the secondary side 150. To do.
