Abstract
A control device of a powertrain with a centrifugal pendulum damper is provided comprising a power transmission shaft which transmits power between a drive source and an automatic transmission, and a centrifugal pendulum damper which is coupled to the power transmission shaft and a connection/disconnection mechanism. The automatic transmission has a transmission mechanism of a hydraulic pressure control type, which includes a transmission control module which performs a control to supply transmission hydraulic pressure to the transmission mechanism. The transmission control module includes a transmission characteristic changing module which changes a control characteristic of transmission hydraulic pressure according to an engagement degree of the connection/disconnection mechanism.
